WHEREAS, after review of the information gathered by staff during public outreach and
public hearings, staff recommends the draft amendments to Tile 17 of the Municipal Code.
NOW, THEREFORE, BE IT RESOLVED by the Council of the City of San Luis
Obispo as follows:
SECTION 1. Findings. Based upon all the evidence, the Commission makes the
following finding:
1. The Zoning Regulations Update comprehensively implements many policies and
programs of the LUCE. As represented in the staff report, additional follow up actions
are needed in order to further implement LUCE policies and programs not addressed
by this Zoning Code Update.
2. The proposed amendments to Title 17 will not cause significant health, safety, or
welfare concerns, since the amendments are consistent with the General Plan and
directly implement City goals and polices.
SECTION 2. Environmental Review. Pursuant to CEQA, the City prepared an Initial
Study/Negative Declaration (IS/ND) to evaluate the potential environmental effects of the
proposed Zoning Regulations Update, as set forth in Exhibit A. This IS/ND addresses all
environmental issues listed in Appendix G of the State CEQA Guidelines. As the Zoning
Regulations Update is consistent with the 2014 LUCE, the IS/ND tiers with and incorporates, by
reference, the City’s previously certified Program Environmental Impact Report [EIR]
(September 2014) prepared for the LUCE pursuant to State CEQA Guidelines Sections 15150
(Incorporation by Reference),15152 (Tiering), and 15168 (Program EIR). The 30-day public
review period for the IS/ND ran from June 20, 2018 to July 19, 2018 and no public or agency
comments were received. Based on the analysis provided within the IS/ND, the City has
concluded that adoption of the Zoning Regulations Update would not result in new significant
impacts on the environment that have not been previously examined or adequately addressed in
the LUCE EIR. No new mitigation measures would be required, and mitigation measures that
were adopted for the LUCE EIR continue to remain applicable, as such measures were
incorporated into the General Plan following City Council’s adoption of the LUCE.
SECTION 3. Action. The City Council hereby repeals and replaces, in its entirety, Title
17 (Zoning) of the San Luis Obispo Municipal Code as set forth in Exhibit B attached hereto and
incorporated herein.
Ordinance No. 1650 (2018 Series) Page 3

of this Ordinance is, for any reason, held to be invalid or unenforceable by a court of
competent jurisdiction, such invalidity or unenforceability shall not affect the validity or
enforcement of the remaining portions of this Ordinance, or any other provisions of the city' s
rules and regulations. It is the city' s express intent that each remaining portion would have been
adopted irrespective of the fact that any one or more subdivisions, paragraphs, sentences,
clauses, or phrases be declared invalid or unenforceable
SECTION 5. A summary of this ordinance, together with the names of Council members
voting for and against, shall be published at least five (5) days prior to its final passage, in The
Tribune, a newspaper published and circulated in this City. This ordinance shall go into effect at
the expiration of thirty (30) days after its final passage.

ZONING REGULATIONS UPDATE
DRAFT INITIAL STUDY/NEGATIVE DECLARATION
(CITYWIDE; GENP-0327-2017)
JUNE 2018, Amended JULY 2018
INTRODUCTION
This document is an Initial Study to evaluate the potential environmental effects of the City of San Luis
Obispo’s proposed Zoning Regulations Update (also referenced as the “Project”). This document has
been prepared in accordance with the relevant provisions of the California Environmental Quality Act
(CEQA) of 1970 (as amended) and the State CEQA Guidelines as implemented by the City of San Luis
Obispo. This Initial Study/Negative Declaration (IS/ND) evaluates the potential direct, indirect, and
cumulative environmental effects associated with the Project, as proposed, and based on reasonable
assumptions outlined in this Initial Study. The proposed Zoning Regulations Update implements the
policies of the City’s Land Use and Circulation Element (LUCE) by classifying, defining, and regulating
the development and uses of land and structures within the City. The Project is described in detail below
(refer to Description of the Project).
BACKGROUND
In 2014, the City adopted a new General Plan Land Use and Circulation Element (LUCE) and certified
the associated Final Program Environmental Impact Report (EIR) (State Clearinghouse No.
2013121019; herein referred to as the “LUCE EIR”). The Land Use Element sets direction for the
orderly development of land within the City’s planning area, and the Circulation Element describes how
transportation will be provided in the community envisioned by the Land Use Element. Following
adoption of the LUCE, City Planning staff began the process of identifying which land use policies
would be most effectively implemented via changes to the City Zoning Regulations.
The Zoning Regulations are the key tool used to implement land use and circulation policies related to
parking management, transit, bicycling, and pedestrian accommodation. Zoning Regulations are
intended to guide the development of the city in an orderly manner, based on the adopted general plan,
to protect and enhance the quality of the natural and built environment, and to promote the public health,
safety and general welfare by regulating the use of land and buildings and the location and basic form of
structures. The Zoning Regulations Update is focused on implementation of the policies and programs in
the LUCE. The Update also provides an opportunity to incorporate best practices and to address
deficiencies identified by staff.
Additional background information regarding the Zoning Regulations Update is available on the City’s
website: http://www.slocity.org/government/department-directory/community-development/planning-
zoning/zoning/zoning-regulations-update
Ordinance No. 1650 (2018 Series)
EXHIBIT A
CITY OF SAN LUIS OBISPO INITIAL STUDY ENVIRONMENTAL CHECKLIST 2018 2
PURPOSE AND LEGAL AUTHORITY
In accordance with the California Environmental Quality Act (Public Resources Code Section 21000, et.
Seq.) and the 2018 State CEQA Guidelines, as lead agency, the City of San Luis Obispo is required to
undertake the preparation of an Initial Study to determine whether the Project would have a significant
environmental impact. If, as a result of the Initial Study, the lead agency finds that there is evidence that
any aspect of the Project may cause a significant environmental effect, the lead agency shall further find
that an EIR is warranted to analyze Project-related and cumulative environmental impacts.
Alternatively, if the lead agency finds that there is no evidence that the Project, either as proposed or as
modified to include the mitigation measures identified in the Initial Study, may cause a significant effect
on the environment, the lead agency shall find that the Project would not have a significant effect on the
environment and shall prepare a Negative Declaration or Mitigated Negative Declaration (ND or MND)
for the Project. Such determination can be made only if “there is no substantial evidence, in light of the
whole record before the lead agency” that such an effect may occur (Section 21080(c), Public Resources
Code). Additionally, Section 15152 of the State CEQA Guidelines allows an EIR or ND to tier from the
environmental analysis of an earlier EIR or ND as follows:
“Tiering refers to using the analysis of general matters contained in a broader EIR (such as one prepared
for a general plan or policy statement) with later EIRs and negative declarations on narrower projects;
incorporating by reference the general discussions from the broader EIR; and concentrating the later EIR
or negative declaration solely on the issues specific to the later project.” The State CEQA Guidelines
states that agencies “are encouraged to tier the environmental analyses which they prepare for separate
but related projects including general plans, zoning changes, and development projects. This approach
can eliminate repetitive discussions of the same issues and focus the later EIR or negative declaration on
the actual issues ripe for decision at each level of environmental review. Tiering is appropriate when the
sequence of analysis is from an EIR prepared for a general plan, policy, or program to an EIR or
negative declaration for another plan, policy, or program of lesser scope, or to a site-specific EIR or
negative declaration. Tiering does not excuse the lead agency from adequately analyzing reasonably
foreseeable significant environmental effects of the project and does not justify deferring such analysis
to a later tier EIR or negative declaration. However, the level of detail contained in a first tier EIR need
not be greater than that of the program, plan, policy, or ordinance being analyzed” (State CEQA
Guidelines Section 15152).
State CEQA Guidelines Section 15168 states that a Program EIR may be used with later activities as
follows:
“Use with Later Activities. Subsequent activities in the program must be examined in the light of the
program EIR to determine whether an additional environmental document must be prepared.
(1) If a later activity would have effects that were not examined in the program EIR, a new Initial Study
would need to be prepared leading to either an EIR or a Negative Declaration.
(2) If the agency finds that pursuant to Section 15162, no new effects could occur or no new mitigation
measures would be required, the agency can approve the activity as being within the scope of the project
covered by the program EIR, and no new environmental document would be required.
(3) An agency shall incorporate feasible mitigation measures and alternatives developed in the program
EIR into subsequent actions in the program.
Ordinance No. 1650 (2018 Series)
EXHIBIT A
CITY OF SAN LUIS OBISPO INITIAL STUDY ENVIRONMENTAL CHECKLIST 2018 3
(4) Where the subsequent activities involve site specific operations, the agency should use a written
checklist or similar device to document the evaluation of the site and the activity to determine whether
the environmental effects of the operation were covered in the program EIR.
(5) A program EIR will be most helpful in dealing with subsequent activities if it deals with the effects
of the program as specifically and comprehensively as possible. With a good and detailed analysis of the
program, many subsequent activities could be found to be within the scope of the project described in
the program EIR, and no further environmental documents would be required.”
The proposed Zoning Regulations Update would make revisions, additions, corrections and
clarifications to various sections of the Zoning Regulations to ensure consistency with and successful
implementation of the LUCE. Pursuant to CEQA, the City of San Luis Obispo has prepared this Initial
Study/Negative Declaration (IS/ND) to evaluate the potential environmental effects of the proposed
Zoning Regulations Update. This IS/ND addresses all environmental issues listed in Appendix G of the
State CEQA Guidelines. Since the Zoning Regulations update is consistent with the 2014 LUCE, this
IS/ND tiers with and incorporates, by reference, the City’s previously-certified Program EIR (September
2014) prepared for the LUCE pursuant to State CEQA Guidelines Sections 15150, 15152, and 15168.
This IS/ND, which is ultimately required to be adopted by the City Council in accordance with CEQA,
is intended as an informational document. Future land uses allowed pursuant to the Draft Zoning
Regulations would be subject to further entitlement review and project-specific use, development, and
design standards as required by the Zoning Regulations, as updated. Additionally, future land uses
would be subject to review on a project-specific basis, and if necessary, project-level CEQA review will
be required to determine project-specific impacts. Evaluation of future project-level impacts would be
too speculative to include in the IS/ND; State CEQA Guidelines Section 15145 (Speculation) states that
“if after thorough investigation, a Lead Agency finds that a particular impact is too speculative for
evaluation, the agency should note its conclusion and terminate discussion of the impact.” Based on the
analysis provided within this IS/ND, the City has concluded that adoption of the Draft Zoning
Regulations Update would not result in new significant impacts on the environment that have not been
previously examined or adequately addressed in the LUCE EIR. No new mitigation measures would be
required, and mitigation measures that were adopted for the LUCE EIR continue to remain applicable,
as such measures were incorporated into the General Plan following City Council’s adoption of the
LUCE.
PRIOR ENVIRONMENTAL DOCUMENTS
The LUCE Program EIR, from which this ND is tiered with, evaluated impacts associated with the
LUCE, including cumulative impacts associated with future development occurring under the LUCE.
The LUCE Program EIR is available for public review at the City of San Luis Obispo Community
Development Department, located at 919 Palm Street, San Luis Obispo, California, 93401. The certified
EIR for the LUCE Update is available on the City’s website:

AMENDMENTS TO THE INITIAL STUDY
Minor amendments to this Initial Study have been made in order to clarify the use of this document in
relation to the LUCE Program EIR, and to provide additional source information as directed by the City
Planning Commission. Such minor amendments are indicated by underlined and italicized text and these
clarifications do not include any substantial revisions and do not change the analysis or conclusions of
the publicly circulated Initial Study / Negative Declaration.
Pursuant to State CEQA Guidelines Section 15073.5 (Recirculation of a Negative Declaration Prior to
Adoption), these clarifications do not constitute a substantial revision of the negative declaration
because: (1) no new, avoidable significant effects are identified and no new mitigation measures or
project revisions are required in order to reduce the level of effect to insignificance; (2) the lead agency
has not determined that any mitigation measures or project revisions would not reduce potential effects
to less than significant, and as such, no new measures or revisions are required.
Pursuant to State CEQA Guidelines Section 15073.5(c), recirculation of the Initial Study / Negative
Declaration is not required because: (1) new project revisions are added in response to written and
verbal comments on the project’s effects identified in the proposed negative declaration which are not
new avoidable significant effects, and (2) new information is added to the negative declaration which
merely clarifies, amplifies, or makes insignificant modifications to the negative declaration.

8. Description of the Project:
In 2014, the City adopted a new General Plan Land Use and Circulation Element (LUCE) and
certified the associated Final Program Environmental Impact Report (EIR) (State Clearinghouse
No. 2013121019). The LUCE is the City’s guiding land use and circulation plan that
encompasses the City’s vision for the future through the year 2035. The land use component sets
direction for “the orderly development of land within the City’s planning area”, and the
circulation component describes “how transportation will be provided in the community
envisioned by the Land Use Element.”
The Zoning Regulations are the key tool used to implement land use and circulation policies
related to the use of land, buildings, location and form of structure, parking management, transit,
bicycling, and pedestrian accommodation. Zoning Regulations are intended to guide the
development of the city in an orderly manner, based on the adopted general plan, to protect and
enhance the quality of the natural and built environment, and to promote the public health, safety
and general welfare. The Zoning Regulations Update is focused on implementation of the
policies and programs in the LUCE. The update also provides an opportunity to incorporate best
practices and to address deficiencies identified by staff in working with the document daily.
Additional information regarding the proposed Zoning Regulations Updates is available online

on the City’s website at: http://www.slocity.org/government/department-directory/community-
development/planning-zoning/zoning/zoning-regulations-update
Key revisions made to the Zoning Regulations are as follows:
1) Restructured the document to improve ease of use
2) Land use tables simplified to consolidate similar uses (e.g., offices), reflect modern land use
practices, and create flexibility over time
3) Created more objective standards for the review of multi-unit residential development and
mixed-use developments consisting of at least two-thirds residential (in response to recent
State law)
4) New development standards for the R-1 and R-2 zones to address neighborhood
compatibility outlined in LUCE policies 2.12 and 2.13
5) Revised parking regulations for motor vehicles and bicycles to achieve the City’s 50 percent
mode shift objective and to provide more precise shared parking provisions
6) Codified conditions routinely applied to specific uses (e.g., alcohol establishments, bed and
breakfast establishments)
7) Clarified provisions for mixed-use developments and required usable and purposeful ground-
floor commercial space for mixed-use developments
8) On a target basis, included regulations to address the current City’s Climate Action Plan
(CAP), with the understanding that the CAP is being updated and subsequent follow-up will
be required (and that many CAP programs are implemented through avenues other than the
Zoning Regulations)
9) Responded to policy direction from the City Council provided at its April 10, 2018 workshop
regarding:
how density is calculated
regulation of rooftop uses
adequacy of alcohol outlet regulations
tiny homes on wheels
consolidating and streamlining the development review process
updating parking regulations
Additional ordinance amendments proposed in conjunction with updating the Zoning
Regulations include applying a Downtown Overlay on parcels zoned C-R (Retail Commercial)
within the and rezoning property on north Broad Street from R-1 to R-1-S.
The proposed Zoning Regulations Update is organized into nine articles that are further broken
up into chapters. Each article contains chapters covering specific topics. Some of the specific
chapters likely to be of high interest are identified below.
Article 1 – Enactment, Applicability, and Enforcement. This Article identifies the purpose and
applicability of the Zoning Regulations, and rules and procedures of interpretation. The updated
regulations now include the document’s relationship to other guidelines and regulations.
Article 2 – Zones, Allowable Uses, and Development and Design Standards. The purpose of this
Article is to identify those land uses that may be established in conjunction with any buildings,
Ordinance No. 1650 (2018 Series)
EXHIBIT A
CITY OF SAN LUIS OBISPO INITIAL STUDY ENVIRONMENTAL CHECKLIST 2018 7
improvements, lots, or premises within the zones established by Chapter 17.06 (Zones
Established and Zoning Map). This Article includes use regulations by zone, including the
purpose and application of each zone, and zone-specific development standards including
density, lot size and dimensions, setbacks, height, and impervious area. Consistent with the Land
Use Element, the Update recommends a minimum density of 20 units per acre in the R-3 zone.
Consistent with the intent of the Medium Density Residential, Medium-High Density
Residential, and High Density Residential land use categories identified in the Land Use
Element, the proposed Update clarifies that at least two units shall be allowed on each parcel in
the R-2 zone, at least three units shall be allowed on each parcel in the R-3 zone, and at least four
units shall be allowed on each parcel in the R-4 zone. In addition, the Update proposes that at
least two units shall be allowed on each parcel in the Office (O) zone. This Article also identifies
prohibited uses and specified requirements for certain uses within identified zones. This Article
includes procedures and standards for overlay zones and Special Focus areas.
Article 3 – Regulations and Standards Applicable to All Zones. This Article identifies site
development and general development standards, such as (and not limited to) permitted
projections into required setbacks, intersection sight distance, height measurement and
exceptions, accessory structures, coverage, density, provisions for fences and walls, night sky
preservation, performance standards related to air quality, energy conservation, water quality,
noise, property maintenance standards, and public art requirements.
Key updates include specifying density for units less than 600 square feet (including studios and
one-bedroom units) as 0.50 density units; providing clarifications and additional provisions for
edge conditions, that support a floor/area ratio (FAR) reduction, buffers between low-density
residential zones or open space area and zones that permit development of higher intensity, and
standards for windows, driveways, trash and recycling areas, and hours of operation that address
privacy, light and glare, and noise; providing provisions for rooftop open space that would
minimize potential noise impacts on residential (R-1) properties as consistent with the Municipal
Code; clarifying hillside development standards consistent with the goals of the Land Use and
Conservation and Open Space Elements; provision of additional limitations, design standards,
pedestrian access requirements for mixed-use developments to further land use and architectural
compatibility, public health, and safety; addition of a new section addressing no net loss of
residential units, which implements General Plan policies guiding land use and housing
preservation; modification of parking requirements to ensure provision of adequate off-street
vehicle and bicycle parking, minimize the negative environmental and urban design impacts that
can result from parking lots, driveways, and drive aisles, and accommodate and encourage
increased use of alternative fuel and zero-emission vehicles; and clarified performance standards
for development.
Article 4 – Regulations for Specific Land Uses and Activities. The purpose of Article 4 is to
establish standards for the location, site planning, development, and operations of certain land
uses that are allowed by within individual or multiple zones, and for activities that require
special standards to mitigate their potential adverse impacts. This Article includes regulations,
performance standards, and restrictions for specific land uses and activities, including accessory
dwelling units and guest quarters, adult entertainment businesses, alcoholic beverage sales, dog
boarding and kennels, bed and breakfast establishments, commercial recreation, convenience
Ordinance No. 1650 (2018 Series)

stores, electronic game amusement centers, family day care, food trucks, general markets and
retail, group housing, high occupancy residential use, home occupations, homeless shelters,
homestay rentals, manufacturing, offices uses, outdoor sales, parking as a principal use, pools
and pool equipment, recreational vehicles, recycling facilities, safe parking, satellite dish
antennas, schools, service and fueling stations, temporary and intermittent uses, utilities, vending
machines, wireless telecommunications facilities.
Article 5 – Noncomformities. This Article addresses nonconforming structures, uses, and lots,
including limits on reconstruction, provisions for exceptions, and associated regulations. This
Article is intended to provide for the correction or removal of nonconforming structures as soon
as practical, but not unduly encumber maintenance and continued use of otherwise sound
structures.
Article 6 – Permit Procedures. This Article 6 establishes the overall structure for the application,
review, and action on City-required permit applications, and identifies and describes those
discretionary permits and other approvals required by these Zoning Regulations in Table 6-1
(Review Authority).
Article 7 – Administration of Zoning Regulations. The purpose of this Article is to describe the
authority and responsibilities of the Director, Planning Commission, Architectural Review
Committee, and Council in the administration of the Zoning Regulations.
Article 8 – Housing-related Regulations. The purpose and intent of this Article are: 1) to promote
the public welfare by increasing the production and availability of affordable housing units and
2) to establish an inclusionary housing requirement which implements General Plan policies
guiding land use and housing development. This Section addresses inclusionary housing
requirements, establishment of the affordable housing fund, in-lieu fees and real property
dedication, incentives, application and program requirements and restrictions, affordable housing
agreements, and fees. This Article also includes Downtown housing conversion regulations,
residential growth-management regulations, and residential occupancy standards.
Article 9 – Definitions. This Article provides definitions of the technical and other terms and
phrases used in Title 17 (Zoning Regulations) as a means of providing consistency in its
interpretation.
9. Project Entitlements: Adoption of Zoning Regulations by the City Council, based on
recommendations from the Planning Commission, formal referral to the Airport Land Use
Commission

10. Surrounding Land Uses and Settings: Multiple (Citywide)
11. Have California Native American tribes traditionally and culturally affiliated with the
project area requested consultation pursuant to Public Resources Code Section 21080.3.1?
If so, has consultation begun?
On April 26, 2018, local Native American tribal groups were formally noticed that an Initial
Study of Environmental Impact was being completed for the proposed Zoning Regulations
Update and invited to provide consultation on the proposed project. No tribal representatives
requested a formal consultation; however, two representatives discussed the proposed Zoning
Regulations with City Staff and one requested specific policy language to be included in the
Zoning Regulation Update (refer to Initial Study Section 17 Tribal Cultural Resources).
12. Other public agencies whose approval is required: County of San Luis Obispo Airport Land
Use Commission (formal referral, determination of consistency with Airport Land Use Plan).
13. Use of this Initial Study as a tiered document.
The LUCE Program EIR evaluated all environmental impacts as required by CEQA and
included measures to mitigate certain impacts. The Zoning Regulations is an implementing
extension of the LUCE. All EIR mitigation measures relevant to Zoning Regulations have
already been added to other policy documents, such as the Land Use Element and Safety
Element. No EIR mitigation measures were specific to the Zoning Regulations Update. However,
as the Zoning Regulations is facilitating growth as directed from the LUCE, a major focus of this
Initial Study is to review for consistency with the LUCE EIR and determine if any of the changes
to the Zoning Regulations would result in new significant impacts not previously evaluated in the
LUCE EIR. As is identified in the following Environmental Factors summary table, no new
potentially significant impacts were identified. It is important to note that under each of the
environmental factors discussed that most of the analysis, proposed mitigation, and conclusions
are from the LUCE as it relates to the Zoning Regulations Update. It is provided in this Initial
Study intending to show the level of environmental review performed as well as used as a basis
to show consistency with the LUCE EIR.

EVALUATION OF ENVIRONMENTAL IMPACTS:
1. A brief explanation is required for all answers except “No Impact” answers that are adequately supported by the
information sources a lead agency cites in the parentheses following each question. A “No Impact” answer is
adequately supported if the referenced information sources show that the impact simply does not apply to projects
like the one involved (e.g. the project falls outside a fault rupture zone). A “No Impact” answer should be explained
where it is based on project-specific factors as well as general standards (e.g. the project will not expose sensitive
receptors to pollutants, based on a project-specific screening analysis).
2. All answers must take account of the whole action involved, including off-site as well as on-site, cumulative as well
as project-level, indirect as well as direct, and construction as well as operational impacts.
3. Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must
indicate whether the impact is potentially significant, less than significant with mitigation, or less than significant.
"Potentially Significant Impact' is appropriate if there is substantial evidence that an effect may be significant. If
there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required.
4. “Negative Declaration: Less Than Significant with Mitigation Incorporated” applies where the incorporation of
mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less than Significant Impact."
The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than
significant level (mitigation measures from Section 19, "Earlier Analysis," as described in (5) below, may be cross-
referenced).
5. Earlier analysis may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has
been adequately analyzed in an earlier EIR or negative declaration (Section 15063 (c) (3) (D)). In this case, a brief
discussion should identify the following:
a) Earlier Analysis Used. Identify and state where they are available for review.
b) Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and
adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects
were addressed by mitigation measures based on the earlier analysis.
c) Mitigation Measures. For effects that are “Less than Significant with Mitigation Measures Incorporated,”
describe the mitigation measures which were incorporated or refined from the earlier document and the extent to
which they addressed site-specific conditions for the project.
6.Lead agencies are encouraged to incorporate into the checklist references to information sources for potential
impacts (e.g. general plans, zoning ordinances). Reference to a previously prepared or outside document should,
where appropriate, include a reference to the page or pages where the statement is substantiated.
7.Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted
should be cited in the discussion.
8. The explanation of each issue should identify:
a) the significance criteria or threshold, if any, used to evaluate each question; and
b) the mitigation measure identified, if any, to reduce the impact to less than significance

Evaluation
The City is located eight miles from the Pacific Ocean and lies at the convergence of two main drainages: The Los Osos Valley
which drains westerly into Morro Bay via Los Osos Creek, and San Luis Valley which drains to the south-southwest into the
Pacific Ocean at Avila Beach via the San Luis Obispo Creek. The topography of the city and its surroundings is generally
defined by several low hills and ridges such as Bishop Peak and Cerro San Luis. These peaks are also known as Morros and
provide scenic focal points for much of the City. The Santa Lucia Mountains and Irish Hills are the visual limits of the area and
are considered the scenic backdrop for much of the City. The surrounding hills have created a hard, urban edge where
development has remained in the lower elevations.
a),b)The Circulation Element and Conservation and Open Space Element (COSE) identify scenic roadways and specific scenic
vistas (Circulation Element Figure 3 Scenic Roadways and COSE Figure 11: Scenic Roadways and Vistas). The LUCE
EIR identifies important scenic corridors, including roadways determined to have high and moderate scenic value (refer to
LUCE EIR Section 4.1 Aesthetics Table 4-1-1. Important Scenic Corridors). Roadways with high scenic value within the
City include: U.S. Highway 101 (from the southern city limit to Marsh Street); South Higuera Street (between Prado Road
and the southern city limit); Broad Street (between Perkins lane and the southern city limit); Tank Farm Road (between
Board and Higuera Street; and east of the UPRR tracks); Johnson Avenue (in the vicinity of Bishop Street); Los Osos
Valley Road (west of Laguna Lane to the city limit); and Santa Rosa Street (between Boysen Avenue and the northern city
limit). Identified scenic features in the City include: the Morros; Santa Lucia Mountains; Irish Hills; Laguna Lake; Open
Space and agricultural fields surrounding the city; historic buildings; Downtown Core streetscape; Mission Plaza; creeks;
particularly San Luis Obispo Creek in the Downtown Core; and Mill Street (between Johnson Avenue and Pepper Street)
(refer to LUCE EIR Section 4.1 Aesthetics, Table 4.1-2. Scenic Features in the City).
The Land Use Element (LUE), Circulation Element, and COSE include policies and programs for open space and hillside
protection, development limits and standards within hillside planning areas. The LUE includes goals, policies and programs
to protect degradation to the existing visual character and its surroundings from the increase of urbanization along the
viewing corridors and scenic roadways. The following policies and programs address potential degradation of existing
visual characteristics: 1.4 Urban Edges Character; 1.8.1 Open Space Protection; 2.3.10 Site Constraints; 4.10 Open Places
and Views; 4.17 New Buildings and Views; 4.20.4 Building Height; 4.26 Visual Resource Study; 6.2.1 Resource Mapping;
6.4 Hillside Policies; and 6.4.1 The City shall maintain comprehensive standards and policies for hillside development. In
addition, the Circulation Element and COSE contains numerous applicable policies and programs in Circulation Element
Section 15 Scenic Roadways and COSE Chapter 9 Views.
LUCE EIR Conclusion
The LUCE EIR concluded that “development under the LUCE Update would introduce new development along viewing
corridors and scenic roadways, including state scenic highways, in the San Luis Obispo area. This could have a substantial
adverse effect on scenic resources or an identified visual resource or scenic vista from a public viewing area. With the
incorporation of the proposed LUCE Update policies and existing City policies, potential impacts to such views are
considered Class III, less than significant” (LUCE EIR Section 4.1 Aesthetics, Impact AES-1).

Proposed Zoning Regulations Update Analysis and Conclusions
The proposed Project includes revisions, additions, corrections, and clarifications to various sections of the Zoning
Regulations in order to provide a regulatory structure to implement the LUCE. The proposed Project would not change the
property development standards (i.e. density, parcel size, setback, height, impervious area) identified for each zone except
for the following:
Residential R-3 zone (change from 18 to 20 units per net acre)
Allow a minimum of two density units on parcels within the R-2 (Medium Residential Density) zone
Allow a minimum of three density units on parcels within the R-3 (Medium-High Density) zone
Allow a minimum of four density units on parcels within the R-4 (High Density) zone
O (Office) zone (change maximum height from 25 to 35 feet).
Allow a minimum of two density units on parcels within the O (Office) zone
PF (Public Facilities) zone – maximum height may be increased up to 50 feet for City-owned facilities
Proposed overlay zone for Upper Monterey (Santa Rosa to Pepper Street) from C-R (Retail Commercial;
maximum height 45 feet) to C-R-D (Downtown overlay; maximum height 50 feet, can be increased up to 75 feet
with incentives)
New requirements for edge conditions would result in beneficial effects by facilitating improved neighborhood
compatibility and transitions between zones. The edge conditions regulations support a buffer between low-density
residential zones or open space areas and zones that permits development of higher intensity. Where multi-unit residential
zones or commercial zones are adjacent to lower intensity residential or open space zones, development shall incorporate
elements in the site design and building design to soften its impact and to result in a compatible transition to the sensitive
zone.
Similar to what was assessed in the LUCE EIR, potential impacts resulting from implementation of the Project may
include: blockage of views by construction equipment and staging areas; disruption of views by temporary signage;
exposure of slopes and removal of vegetation; structural development within identified scenic areas; and view blockages by
new structures, signs, and parking areas. The proposed Project does not include any updates or amendments that would be
inconsistent with existing General Plan policies and architectural guidelines in place to protect scenic vistas and other
scenic resources. The proposed changes to allow increases in residential density within the R-3 zone and establishing a
minimum number of dwelling units within the R-2, R-3, R-4, and O zones would be consistent with the analysis and
conclusions of the LUCE EIR, because: these changes are consistent with adopted LUCE maximum dwelling density for
the Medium-High Density Residential land use designation (20 units per acre, as shown in LUE Table 4. Residential
Population Assumptions), the changes would be consistent with the intention of the Medium, Medium-High and High
Density Residential and Office land use designations to provide multi-family and other residential opportunities (see LUE
Table 1. General Plan Land Use Designations and Development Standards within the LUCE Planning Sub-area),
development of housing projects pursuant to the proposed regulations would result in similar impacts and conclusions as
disclosed in the LUCE EIR, and future development would be subject to performance and design standards established for
these multi-family residential and office zones.
The proposed changes to allow 10 feet of increased height in the O zone (up to 35 feet) and allowance of two density units
on each parcel in the O zone would be consistent with the analysis and conclusions presented in the LUCE EIR because the
existing setting includes buildings in the O zone that exceed 25 feet in height (as currently allowed based on consideration
of an Administrative Use Permit), existing O zones in the City currently support a mix of residential and office uses, and
future development would be subject to site and project-specific analysis including consistency with General Plan policies
and Community Design Guidelines that require consideration of scenic resources during the architectural review and
entitlement process. The proposed changes to allow 15 feet of increased height in the PF zone (limited to City-owned
facilities), would not be inconsistent with the analysis and conclusions presented in the LUCE EIR because future
development would be subject to site and project-specific analysis including consistency with General Plan policies and
Community Design Guidelines that require consideration of scenic resources during the architectural review and
entitlement process.

The proposed overlay zone for Upper Monterey (from C-R to C-R-D) would allow for additional building height along this
corridor, resulting in an expected increase of 5 feet, with provisions for an additional 30 feet based on incorporation of
specific incentives identified in the Zoning Regulations Update. This would not be inconsistent with the analysis and
conclusions presented in the LUCE EIR because allowable density would not change, the potential impacts associated with
potential future structural development in compliance with the proposed regulations would not result in any new
significant impacts beyond what is identified in the LUCE EIR as identified in LUCE EIR Section 4.1 Aesthetics, Impact
AES-1), and future development would be subject to site and project-specific analysis including consistency with General
Plan policies and Community Design Guidelines that require preparation of visual resource studies and consideration of
scenic resources during the architectural review and entitlement process (refer to LUE Chapter 4 (Downtown) 4.17 New
Buildings and Views, 4.20 Design Principles, 4.20.4 Building Height: “New buildings shall fit within the context and scale
of existing development, shall respect views from, or sunlight to, publicly-owned gathering places…and should be stepped
back…to maintain a street façade that is consistent with the historic pattern of development” and Conservation and Open
Space Element Chapter 9 (Views) 9.1.2 Urban development: “Urban development should reflect its architectural context”,
9.1.5 View protection in new development, 9.2.1 Views to and from public places, and 9.3.5 Visual assessments: “Require
evaluations (accurate visual simulations) for projects affecting important scenic resources and views from public places”.
Furthermore, the proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future
land uses that occur pursuant to the proposed Project would be required to conform to all applicable regulations,
performance standards and design standards that address the preservation of scenic vistas and scenic resources, including
those set forth in the Zoning Regulations, as updated, and the General Plan. Pursuant to CEQA, future new land uses that
occur pursuant to the proposed Zoning Regulations update would be subject to their own environmental review on a
project-by-project basis to assess impacts on scenic vistas. Therefore, the proposed Project would not have a substantial
adverse effect on a scenic vista. Impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not allow new development in areas where such development is prohibited under the LUCE. The
proposed modifications to height development standards would result in potentially significant impacts to scenic views
consistent with LUCE EIR, Section 4.1 Aesthetics, Impact AES-1, and the resulting impact would be less than significant
based on compliance with the General Plan. Therefore, there would be no new scenic vista impacts that have not been
previously examined or adequately addressed in LUCE EIR Section 4.1 Aesthetics.
c) As described in LUCE EIR Section 4.1 Aesthetics, the City combines a compact urban form in a rural setting and does not
have one character, but several, transitioning from urban in its Downtown Core to more suburban along the edges. The city
has been successful in maintaining an urban or suburban character, while retaining a more rural character outside the city.
This is most clearly demonstrated in the Laguna Lake area where Los Osos Valley Road (LOVR) leaves the city, and the
relative dense housing stops abruptly, giving way to open space and agriculture in the county. A similar phenomenon is
visible in many other areas, notably as one travels west on Foothill Boulevard; south on Johnson Avenue and turns left on
Orcutt Road; or even as one leaves the city on Broad Street to the south. To a large extent, this is also true as a traveler
leaves the city to the north, on either Highway 1 or 101. LUCE EIR Section 4.1 Aesthetics includes descriptions of several
defined areas of the city, including: Downtown Core; Older Downtown Residential Neighborhoods; Foothill Boulevard
Neighborhoods; Johnson Avenue Neighborhoods; Neighborhoods South of Tank Farm Road; Laguna Lake Residential
Area; Laguna Lake Freeway Commercial and Auto Center Area; Mid‐ and South Higuera Street; and South Broad Street.
LUCE EIR Conclusion
The LUCE emphasizes both reuse of existing urbanized lands, infill development on vacant parcels, and new development
on vacant parcels near urban areas. The LUCE EIR concludes that “the development of such areas could degrade the
existing visual character and its surroundings. With the incorporation of the proposed LUCE Update and existing City
policies and programs, potential impacts related to existing visual character changes are considered Class III, less than
significant” (LUCE EIR Section 4.1 Aesthetics, Impact AES-2).

Proposed Zoning Regulations Update Analysis and Conclusions
Similar to what was assessed in the LUCE EIR, the intensification of land use anticipated to occur in certain areas of the
city may be considered degradation of the existing visual character and its surroundings to some viewers due to the
presence of larger buildings and the corresponding reduction in vacant land within the city’s framework. However, the
reuse and intensification of already developed areas would be expected to reduce the pressure for development at the city’s
periphery, thus minimizing the potential for the loss of open lands adjacent to the city, protected for their visual character.
The LUCE states that much of the intensification and reuse that would occur would also generally be expected to enhance
the visual character of the community. In particular, it is anticipated that future redevelopment in the South Broad Street
Special Planning Area would enhance visual quality by adding attractive infill development (LUCE EIR Section 4.1
Aesthetics).
As required by the existing and proposed Zoning Regulations, new development projects are subject to varying levels of
design review by the Community Development Director, Architectural Review Commission, Planning Commission, and
when required, the City Council to ensure consistency with the General Plan and Community Design Guidelines. The
proposed Project includes revisions, additions, corrections, and clarifications to various sections of the Zoning Regulations
in order to provide a regulatory structure to implement the LUCE. The proposed Project would not change the property
development standards (i.e. density, parcel size, setback, height, impervious area) identified for each zone except for the
standards noted above (refer to Initial Study Section 1 Aesthetics, discussion under a). The proposed Project would not
result in new development in areas where such development is prohibited under the LUCE.
The proposed Project does not include any updates or amendments that would be inconsistent with existing General Plan
policies and architectural guidelines in place to protect visual character. The proposed changes to increase density within
the R-3 zone and allow a minimum number of dwelling units within the R-2, R-3, R-4 and O zones would be consistent
with the analysis and conclusions of the LUCE EIR, because: these changes are consistent with adopted LUCE maximum
dwelling density for the Medium-High Density Residential land use designation (20 units per acre, as shown in LUE Table
4. Residential Population Assumptions), the changes would be consistent with the intention of the Medium, Medium-High
and High Density Residential and Office land use designations to provide multi-family and other residential opportunities
(see LUE Table 1. General Plan Land Use Designations and Development Standards within the LUCE Planning Sub-area),
development of housing projects pursuant to the proposed regulations would result in similar impacts and conclusions as
disclosed in the LUCE EIR, and future development would be subject to performance and design standards established for
these multi-family residential and office zones.
The proposed changes to allow 10 feet of increased height in the O zone (up to 35 feet) and allowance of two density units
on each parcel in the O zone would not be inconsistent with the analysis and conclusions presented in the LUCE EIR
because the existing setting includes buildings in the O zone that exceed 25 feet in height (as currently allowed based on
consideration of an Administrative Use Permit), existing O zones in the City currently support a mix of residential and
office uses, and future development would be subject to site and project-specific analysis including consistency with
General Plan policies and Community Design Guidelines that require consideration of scenic resources during the
architectural review process.
The proposed changes to allow 15 feet of increased height in the PF zone (limited to City-owned facilities), would not be
inconsistent with the analysis and conclusions presented in the LUCE EIR because future development would be subject to
site and project-specific analysis including consistency with General Plan policies and Community Design Guidelines that
require consideration of scenic resources during the architectural review process.
The proposed overlay zone for Upper Monterey (from C-R to C-R-D) would allow for additional building height along this
corridor, resulting in an expected increase of 5 feet, with provisions for an additional 30 feet based on incorporation of
specific incentives identified in the Zoning Regulations Update. This would be consistent with the analysis and conclusions
presented in the LUCE EIR because allowable density would not change, and future development would be subject to site

The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable regulations, performance standards
and design standards that address the visual character and edge conditions, including those set forth in the Zoning
Regulations, as updated, and the General Plan. Pursuant to CEQA, future new land uses that occur pursuant to the proposed
Zoning Regulations update would be subject to their own environmental review on a project-by-project basis to assess
impacts on scenic vistas. Therefore, the proposed Project would not have a substantial adverse effect on visual character.
Impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not allow new development in areas where such development is prohibited under the LUCE. The
proposed modifications to height development standards would result in potentially significant impacts to visual character
consistent with LUCE EIR, Section 4.1 Aesthetics, Impact AES-2, and the resulting impact would be less than significant
based on compliance with the General Plan. Therefore, there would be no new visual character impacts that have not been
previously examined or adequately addressed in LUCE EIR Section 4.1 Aesthetics.
d)Existing development in the City, including private development and associated exterior lighting, street lights within the
public right-of-way, and other lighting associated with parks and public facilities generate ambient light visible within the
City. Additional existing sources of light and glare include glass windows and facades and vehicle headlights. All
development in the City is subject to the City’s Night Sky Preservation Ordinance, which establishes “outdoor lighting
regulations that encourage lighting practices and systems that will: A. Permit reasonable uses of outdoor lighting for
nighttime safety, utility, security and enjoyment while preserving the ambience of night; B. Curtail and reverse any
degradation of the nighttime visual environment and the night sky; C. Minimize glare and obtrusive light by limiting
outdoor lighting that is misdirected, excessive, or unnecessary; D. Help protect the natural environment from the damaging
effects of night lighting; E. Meet the minimum requirements of the California Code of Regulations for Outdoor Lighting
and Signs (Title 24, Chapter 6)”.
LUCE EIR Conclusion
The LUCE EIR states that “proposed development in accordance with the LUCE Update would introduce new sources of
light and glare. However, adherence to policies included in the Zoning Ordinance and Community Design Guidelines
would reduce potential impacts to a Class III, less than significant, level” (LUCE EIR Section 4.1 Aesthetics, Impact AES-
3).
Proposed Zoning Regulations Update Analysis and Conclusions
Similar to the impact analysis for the LUCE, development in accordance with the proposed Project could increase the
ambient nighttime lighting throughout the city. Increased glare could potentially occur as a result of building materials,
roofing materials, and windows reflecting sunlight. Areas that would experience the greatest potential for increased lighting
are those areas likely to experience the greatest development potential. The proposed Project does not include any updates
or amendments that would be inconsistent with the Night Sky Preservation Ordinance. In addition, future development is
subject to proposed performance standard regulations for light and glare, which state that “Every existing or proposed
use, activity, or process or portion thereof producing glare shall be shielded in such a manner that the glare is not
perceptible at or beyond any property line” (proposed Zoning Regulations Section 17.74.080, Light and Glare).
The proposed Project, by itself, does not propose or authorize any development. Future land uses that occur pursuant to the
proposed Zoning Regulations update would be required to conform to all applicable regulations performance standards and
design standards that address lighting and glare, including those of the Night Sky Preservation Ordinance. Therefore, the
proposed Zoning Regulations Update would not have a substantial adverse effect related to light and glare. Impacts would

Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not allow new development in areas where such development is prohibited under the LUCE.
Therefore, there would be no physical changes related to increased light or glare that have not been previously examined or
adequately addressed in LUCE EIR Section 4.1 Aesthetics.
2. AGRICULTURE RESOURCES. Would the project:
a)Convert Prime Farmland, Unique Farmland, or Farmland of
Statewide Importance (Farmland), as shown on the maps
pursuant to the Farmland Mapping and Monitoring Program of
the California Resources Agency, to non-agricultural use?
1, 4 X
b)Conflict with existing zoning for agricultural use or a
Williamson Act contract?1, 4 X
c)Involve other changes in the existing environment which, due
to their location or nature, could result in conversion of
Farmland to non-agricultural use?
1, 4 X
Evaluation
The city is located in the heart of San Luis Obispo County and the Central Coast Region, both of which are important key
agricultural centers within the State of California. The region’s agricultural industry is an important part of the local economy.
It provides employment and income directly for those in agriculture, and it helps drive growth in the tourism industry, which in
turn generates further economic activity and consumer spending.
a), c) As shown on LUCE EIR Section 4.2 Agricultural Resources, Figure 4.2-2 City of SLO Planning Area Prime Soils in
Agriculture, Prime Farmland and Farmland of Statewide Importance is present within the City. The LUE includes several
policies specific to open space and agricultural protection, including but not limited to the following:
Policy 1.9.1. Agricultural Protection: The City shall support preservation of economically viable agricultural operations
and land within the urban reserve and city limits. The City should provide for the continuation of farming through steps
such as provision of appropriate general plan designations and zoning.
Policy 1.9.2. Prime Agricultural Land: The City may allow development on prime agricultural land if the development
contributes to the protection of agricultural land in the urban reserve or greenbelt by one or more of the following methods,
or an equally effective method: acting as a receiver site for transfer of development credit from prime agricultural land of
equal quantity; securing for the City or for a suitable land conservation organization open space or agricultural easements
or fee ownership with deed restrictions; helping to directly fund the acquisition of fee ownership or open space easements
by the City or a suitable land conservation organization. Development of small parcels which are essentially surrounded by
urbanization need not contribute to agricultural land protection.
LUCE EIR Conclusion
The LUCE EIR concluded that “future development in accordance with the LUCE Update could occur on prime farmland,
unique farmland, and/or farmland of statewide importance. Buildout within the City Limits would result in Class II,
significant but mitigable impacts to agricultural conversion” (LUCE EIR Section 4.2 Agricultural Resources, Impact AG-
2).
The LUCE EIR determined that Impact AG-2 would be mitigated to less than significant by implementation of the
following policy, which was incorporated in the adopted LUE: “LUE Policy 1.8.1. Open Space Protection: Within the

City's planning area and outside the urban reserve line, undeveloped land should be kept open. Prime agricultural land,
productive agricultural land, and potentially productive agricultural land shall be protected for farming. Scenic lands,
sensitive wildlife habitat, and undeveloped prime agricultural land shall be permanently protected as open space”.
Proposed Zoning Regulations Update Analysis and Conclusions
Similar to the analysis in the LUCE EIR, build-out pursuant to the Zoning Regulations update would facilitate the
development and redevelopment of lands within the City of San Luis Obispo, and future development in accordance with
the Project could occur on prime farmland, unique farmland, farmland of statewide importance, and other farmland within
the City. Adherence to the City’s standard of practice regarding agricultural soils and farmland for new development
projects and its enforcement of the General Plan policies regarding preservation of farmland will ensure that development
on prime farmland, unique farmland, and/or farmland of statewide importance is a less than significant impact. In addition,
individual development would be required to undergo separate environmental review, which may result in specific impacts
that require project specific mitigation consistent with these existing policies.
The proposed Project, by itself, does not propose or authorize any development. As future development is proposed, the
City will be required to ensure consistency with the General Plan. Therefore, the proposed Zoning Regulations Update
would not have a substantial adverse effect on agricultural resources. Impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project does not include any updates or amendments that would be inconsistent with General Plan policies in
place to ensure no net loss of Farmland, and there are no proposed changes to allowable lot coverage that would have the
potential to result in increased impacts to agricultural resources not already assessed in the LUCE EIR. The proposed
Project does not include any changes that would result in the conversion of Farmland beyond what was analyzed in the
LUCE EIR, because the proposed Project would not result in new development in areas where such development is
prohibited under the LUCE. Therefore, there would be no physical changes related to agricultural resource impacts that
have not been previously examined or adequately addressed in LUCE EIR Section 4.2 Agricultural Resources.
b) There are no large tracks of land within the city limits currently in commercial agricultural production, with the exception
of the San Luis Obispo City Farm located adjacent to Calle Joaquin Road and U.S. Highway 101. In addition, four
community gardens provide small plots of land to the public to grow small-scale agriculture, but these are within the urban
context of the developed city. The largest piece of land adjacent to the city in production is the San Luis Ranch area, an
identified Specific Plan Area that is currently pending annexation into the City. As shown on LUCE EIR Section 4.2
Agricultural Resources, Figure 4.2-3 City of SLO Planning Area Williamson Act Properties, there are no areas within the
City limits that are under Williamson Act contract.
LUCE EIR Conclusion
The LUCE EIR states that “the LUCE Update could alter the existing land use and zoning on sites throughout the city and
may result in incompatibilities with adjacent urban and agricultural uses. However, the General Plan reduces land use
conflicts through policies and plan review. Therefore, impacts that would occur from development would be Class III, less
than significant” (LUCE EIR Section 4.2 Agricultural Resources, Impact AG-1). The LUCE EIR states that adherence to
the City’s standard of practice regarding agricultural compatibility for new development projects and its enforcement of the
General Plan policies regarding preservation of agricultural operations will ensure that agricultural uses and compatibility
with urban development is a less than significant impact.
Proposed Zoning Regulations Update Analysis and Conclusions
Similar to the analysis in the LUCE EIR Section 4.2 Agricultural Resources, buildout of the City pursuant to the Zoning
Regulations Update would facilitate the development and redevelopment of residential uses in areas of the city near

agricultural areas. Residential development adjacent to farmland can result in impacts related to existing farm operations,
including direct impacts related to fencing, theft, soil compaction and crop damage due to trespass, and decreased air
quality and creation of fugitive dust (which can affect crop production). Placement of residences adjacent to cultivated
agriculture can also have economic impacts to growers. Based on compliance with the General Plan, including but not
limited to COSE Program 8.7.1 (Protect open space resources), potential impacts would be less than significant.
The proposed Project, by itself, does not propose or authorize any development. As future development is proposed, the
City will be required to ensure consistency with the General Plan. Therefore, the proposed Zoning Regulations Update
would not have a substantial adverse effect on agricultural resources. Impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project does not include any updates or amendments that would be inconsistent with General Plan policies in
place to minimize potential land use incompatibilities, and there are no proposed changes to allowable lot coverage that
would have the potential to result in increased impacts to agricultural resources not already assessed in the LUCE EIR. The
proposed Project does not include any changes that would result in any addition agricultural impacts beyond what was
analyzed in the LUCE EIR, because the proposed Project would not result in new development in areas where such
development is prohibited under the LUCE. Therefore, there would be no physical changes related to agricultural resource
impacts that have not been previously examined or adequately addressed in LUCE EIR Section 4.2 Agricultural Resources.

Evaluation
Air quality in the San Luis Obispo region of the County is characteristically different than other regions of the County (i.e., the
Upper Salinas River Valley and the East County Plain), although the physical features that divide them provide only limited
barriers to transport pollutants between regions. The County is designated non-attainment for the one‐hour California Ambient
Air Quality Standards (CAAQS) for ozone and the CAAQS for respirable particulate matter (PM10). The County is designated
attainment for national ambient air quality standards (NAAQS).
a)The San Luis Obispo Air Pollution Control District (SLOAPCD) adopted the 2001 Clean Air Plan (CAP) in 2002, and the
CAP has not been updated following certification of the LUCE EIR. The 2001 CAP is a comprehensive planning document
intended to provide guidance to the SLOAPCD and other local agencies, including the City, on how to attain and maintain
the state standards for ozone and PM10. The CAP presents a detailed description of the sources and pollutants which
impact the jurisdiction, future air quality impacts to be expected under current growth trends, and an appropriate control
strategy for reducing ozone precursor emissions, thereby improving air quality.

LUCE EIR Conclusion
The LUCE EIR included a consistency analysis, which evaluated implementation of the LUCE against the land use goals,
policies, control measures, and population projections contained in the CAP (refer to LUCE EIR Section 4.3 Air Quality,
Impact AQ-2, Long-term). Based on this analysis, the LUCE EIR concluded that “implementation of the LUCE Update
would not be consistent with the assumptions contained in the most recent version of the APCD’s CAP even with the
incorporation of the proposed LUCE Update policies and existing City policies. Thus, long‐term air quality impacts are
considered Class I, significant and unavoidable” (LUCE EIR Section 4.3 Air Quality, Impact AQ-2, Long-term). Upon
certification of the LUCE EIR and approval of the LUCE Update, the City adopted a Statement of Overriding
Considerations for this significant and unavoidable impact.
Proposed Zoning Regulations Update Analysis and Conclusions
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable regulations and LUCE and COSE
policies and programs that relate to air quality (refer to COSE Section 2 Air) and CAP Control Measures (refer to LUCE
EIR, Section 4.3 Air Quality, Table 4.3-1 Clean Air Plan Control Measure Consistency with LUCE Update). Pursuant to
CEQA, future new land uses that occur pursuant to the proposed Zoning Regulations Update would be subject to their own
environmental review on a project-by-project basis to assess impacts on air quality. Therefore, the proposed Project would
not result in a significant air quality impact not examined or adequately addressed in the LUCE EIR.
Conclusion. The proposed Project would make revisions, additions, corrections and clarifications to various sections of the
Zoning Regulations to ensure consistency and successful implementation of the LUCE. The proposed Zoning Regulations
Update would not allow new development in areas where such development is prohibited under the LUCE. Therefore,
there would be no new air quality impacts that have not been previously disclosed and addressed in LUCE EIR Section 4.3
Air Quality.
b), c) Both the US Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) have established
ambient air quality standards for common pollutants. These ambient air quality standards are levels of contaminants
representing safe levels that avoid specific adverse health effects associated with each pollutant. The ambient air quality
standards cover what are called “criteria” pollutants because the health and other effects of each pollutant are described in
criteria documents. Areas that meet ambient air quality standards are classified as attainment areas, while areas that do not
meet these standards are classified as nonattainment areas. San Luis Obispo is currently designated as nonattainment for the
1-hour and 8-hour State standards for ozone and the 24-hour State standard for PM10.
LUCE EIR Conclusion
Construction-related (Short-term) Impacts
Construction emissions are described as “short‐term” or temporary in duration and have the potential to have an adverse
effect on air quality. Ozone precursor emissions (i.e., ROG and NOx) are primarily associated with gas and diesel
equipment exhaust and the application of architectural coatings. Fugitive dust emissions (i.e., PM10 and PM2.5) are
primarily associated with site preparation and vary as a function of such parameters as soil silt content, soil moisture, wind
speed, acreage of disturbance area, and vehicle miles traveled (VMT) by construction vehicles on‐ and off‐site. Typical
construction equipment associated with development and redevelopment projects includes dozers, graders, excavators,
loaders, and trucks.
The LUCE EIR concluded that “implementation of the LUCE Update would involve construction of development projects
that generate short‐term emissions of criteria air pollutants and ozone precursors. Emissions from individual construction
projects could exceed APCD’s project‐level significance thresholds. Thus, implementation of the LUCE Update could
result in construction‐generated emissions that violate or contribute substantially to an existing or projected air quality

violation, contribute a cumulatively considerable net increase of criteria air pollutants for which the region is designated as
non‐attainment, and/or expose sensitive receptors to substantial pollutant concentrations. Adherence to relevant policies
and implementation of APCD-recommended project‐specific mitigation measures would reduce potential short‐term
impacts to a less-than‐significant level. Thus, construction‐generated air quality impacts are considered Class II, significant
but mitigable” (LUCE EIR Section 4.3 Air Quality, Impact AQ-1, Short-term). The LUCE EIR determined that potential
air quality impacts would be minimized to less than significant through implementation of mitigation measures identified
by the APCD.
Proposed Zoning Regulations Update Analysis and Conclusions
Although it is not possible to speculate on the exact type, number, location, or timing of future development projects or on
the precise nature or degree of environmental impacts associated with such projects, implementation of the Zoning
Regulations Update would require construction activity resulting in the generations of criteria air pollutant and ozone
precursor emissions. The LUCE EIR provides estimates of construction emissions of ROG, NOX, PM10, and PM2.5 using
CalEEMod based on the description of land use changes (dwelling units and commercial square feet) associated with
buildout under the LUCE. The LUCE EIR notes that daily emissions could exceed APCD’s applicable thresholds of
significance for construction activities (e.g., 137 lb/day for ROG and NOX combined) (LUCE EIR Section 4.3 Air
Quality).
The APCD specifies construction mitigation measures designed to reduce emissions of ROG, NOx, PM10, and PM2.5
(both fugitive and exhaust) (refer to APCD 2012 CEQA Handbook). These include standard mitigation measures, best
available control technology (BACT), and construction activity management plan (CAMP) and off‐site mitigation for
construction equipment emissions; along with short and expanded lists for fugitive dust emissions. The City shall ensure
the implementation of the most current APCD‐recommended construction mitigation measures to reduce
construction‐generated emissions to less‐significant levels as defined by APCD. Individual development would be required
to undergo separate environmental review, which may result in specific impacts that require project specific mitigation
consistent with the most current APCD‐recommended construction mitigation measures. As stated in APCD’s CEQA Air
Quality Handbook, if estimated construction emissions are expected to exceed either of the APCD Quarterly Tier 2
thresholds of significance after the standard and BACT measures are accounted for, then an APCD approved CAMP and
off‐site mitigation would need to be implemented to reduce air quality impacts to a less‐than‐significant level. In addition,
all fugitive dust sources shall be managed to ensure adequate control below 20% opacity as identified by Rule 401, for
which compliance is required by law. In addition, future development will be subject to proposed performance standards,
which state that “No use or activity shall be conducted without first obtaining any required permit from the County Air
Pollution Control District” and “Uses shall be conducted to prevent dust or other airborne material from crossing
property lines” (proposed Zoning Regulations Section 17.74.030). Adherence to relevant policies and implementation of
APCD‐recommended project‐specific mitigation measures would reduce potential impacts associated with future
development under the proposed Zoning Regulations Update to a less‐than‐significant level. Thus, consistent with the
LUCE EIR, construction‐generated air quality impacts are considered significant but mitigable.
Existing Regulatory Requirements Related to Asbestos and Equipment Operation
In addition to construction-related emissions, naturally occurring asbestos (NOA) has been identified by the state Air
Resources Board as a toxic air contaminant. Serpentine and ultramafic rocks are very common throughout California and
may contain naturally occurring asbestos. The APCD has identified that NOA may be present throughout the City of San
Luis Obispo (APCD 2012 CEQA Handbook, Technical Appendix 4.4), and under the ARB Air Toxics Control Measure
(ATCM) for Construction, Grading, Quarrying, and Surface Mining Operations (93105) are therefore required to provide
geologic evaluation prior to any construction activities. As such, impacts related to future development pursuant to the
Zoning Regulations Update are considered significant but mitigable based on compliance with existing regulations.
Future development under the Zoning Regulations Update may require demolition of non-historic structures and grading,
which has the potential to disturb asbestos that is often found in older structures as well as underground utility pipes and
pipelines (i.e. transite pipes or insulation on pipes). Demolition can have potential negative air quality impacts, including

issues surrounding proper handling, demolition, and disposal of asbestos containing material (ACM). As such, future
projects may be subject to various regulatory jurisdictions, including the requirements stipulated in the National Emission
Standard for Hazardous Air Pollutants (40CFR61, Subpart M – asbestos NESHAP). Impacts related to the proposed
demolition of existing structures are considered to be significant but mitigable based on compliance with existing
regulations.
In addition, future projects may be subject to CARB or APCD permitting requirements. This includes portable equipment,
50 horsepower (hp) or greater or other equipment listed in the APCD’s 2012 CEQA Handbook, Technical Appendices,
page 4-4. Truck trips associated with the proposed excavated site material (i.e., soils) that will be cut from the site may also
be a source of emissions subject to SLO APCD permitting requirements, subject to a specifically selected truck route. The
specific requirements and exceptions in the regulations can be reviewed at the following web sites:
https://www.arb.ca.gov/msprog/truck-idling/factsheet.pdf and https://www.arb.ca.gov/regact/2007/ordiesl07/frooal.pdf.
Impacts related to vehicle and heavy equipment emissions are considered to be significant but mitigable based on
compliance with existing regulations.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Zoning Regulations Update would be required to conform to all applicable regulations,
performance standards, and design standards as required by the City’s Municipal Code, the APCD, and CARB. Therefore,
potentially significant impacts would be mitigated to less than significant through compliance with existing regulations and
guidelines.
Conclusion. The proposed Project would make revisions, additions, corrections and clarifications to various sections of the
Zoning Regulations to ensure consistency and successful implementation of the LUCE. The proposed Zoning Regulations
Update would not allow new urban development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new air quality impacts that have not been previously examined or adequately addressed in
LUCE EIR Section 4.3 Air Quality.
LUCE EIR Conclusion
Operational (Long-term) Impacts.
As described in the APCD 2012 CEQA Handbook, “operational impacts are focused primarily on the indirect emissions
(i.e., motor vehicles) associated with residential, commercial and industrial development. Air pollutant emissions from
urban development can result from a variety of sources, including motor vehicles, wood burning appliances, natural gas
and electric energy use, combustion-powered utility equipment, paints and solvents, equipment or operations used by
various commercial and industrial facilities, heavy-duty equipment and vehicles and various other sources”. A program
level environmental review of long-term impacts resulting from implementation of the LUCE is presented in the LUCE
EIR, and as directed by the APCD 2012 CEQA Handbook, consist of a qualitative analysis based upon criteria such as
prevention of urban sprawl and reduced dependence on automobiles, and by comparing consistency of the project with the
Transportation and Land Use Planning Strategies outlined in the APCD's Clean Air Plan (refer to a) above, and LUCE EIR,
Section 4.3 Air Quality, Table 4.3-1 Clean Air Plan Control Measure Consistency with LUCE Update).
The LUCE EIR concluded that “implementation of the LUCE Update would involve operation of development projects
that generate long-term emissions of criteria air pollutants and ozone precursors. Implementation of the LUCE Update
would not result in the exposure of sensitive receptors to substantial sources of local carbon monoxide concentrations,
odors, or TACs. However, with regards to criteria air pollutants and precursors implementation of the LUCE Update would
not be consistent with the assumptions contained in the most recent version of the APCD’s Clean Air Plan even with the
incorporation of the proposed LUCE Update policies and existing City policies. Thus, long‐term air quality impacts are
considered Class I, significant and unavoidable” (LUCE EIR Section 4.3 Air Quality, Impact AQ-2 Long-term). Upon
certification of the LUCE EIR and approval of the LUCE Update, the City adopted a Statement of Overriding
Considerations for this significant and unavoidable impact.

Proposed Zoning Regulations Update Analysis and Conclusions
Consistent with the LUCE EIR, overall, implementation of the Zoning Regulations Update, including proposed
modifications to minimum dwelling units on R-2, R-3, R-4, and O zoned lots, and the proposed change to increase
allowable density on R-3 lots (as consistent with the General Plan), and proposed development occurring within the Upper
Monterey Overlay zone, would involve operation of development projects that generate long‐term emissions of criteria air
pollutants and ozone precursors. With regards to criteria air pollutants and precursors, similar to the conclusion in the
LUCE EIR, implementation of the Project would not be consistent with the assumptions contained in the most recent
version of the APCD’s Clean Air Plan even with implementation of COSE policies and programs (refer to COSE Section 2
Air Quality) and compliance with the LUE. Consistent with the conclusions of the LUCE EIR, long‐term air quality
impacts resulting from future development constructed pursuant to the proposed Zoning Regulations Update are considered
significant and unavoidable.
The proposed Project, by itself, does not propose or authorize any development. Future land uses that occur pursuant to the
proposed Zoning Regulations Update would be required to conform to all applicable regulations performance standards
and design standards that address sustainability and air quality, including those of the Zoning Regulations, as updated, and
the LUCE. Pursuant to CEQA, future new land uses that occur pursuant to the proposed Zoning Regulations Update would
be subject to their own environmental review on a project-by-project basis to assess impacts on air quality. Therefore, the
proposed Project would not result in a significant air quality impact not examined or adequately addressed in the LUCE
EIR.
Conclusion. The proposed Project would make revisions, additions, corrections and clarifications to various sections of the
Zoning Regulations to ensure consistency and successful implementation of the LUCE. The proposed Zoning Regulations
Update would not allow new development in areas where such development is prohibited under the LUCE. Consistent with
the LUCE, the proposed Project may result in beneficial environmental impacts on air quality by developing incentives in
the Downtown area to reduce the use of cars, including provisions that would allow for corner stores in residential areas,
further allowing upper-story residential uses in commercial areas, providing for an enhanced pedestrian experience in the
Downtown, providing additional dwelling units within medium to high residentially-zoned areas, maintaining rural
character and protecting natural resource areas, incorporating further sustainability standards into land use regulations, and
adjusting parking requirement to achieve multi-modal objectives identified in the General Plan. Therefore, there would be
no new air quality impacts that have not been previously disclosed and addressed in LUCE EIR Section 4.3 Air Quality.
d) LUCE EIR Conclusion
The San Luis Obispo area is designated as an attainment area for carbon monoxide (CO) for both the CAAQS and
NAAQS. The analysis in the LUCE EIR states that if a project would not increase traffic volumes at affected intersections
to more than 44,000 vehicles per hour (or more than 24,000 vehicles per hour where vertical and/or horizontal mixing is
substantially limited (e.g., tunnel, parking garage, bridge underpass, natural or urban street canyon, below‐grade roadway)
then implementation would not result in or contribute to a CO violation. The LUCE EIR concluded that implementation of
the LUCE Update would not result in the addition of vehicles to affected intersections that exceed these recommended
levels.
With regards to the exposure of sensitive receptors to toxic air contaminant (TAC) sources, there are no freeways or urban
roadway segments with traffic volumes that exceed 100,000 vehicles per day and no rural roadways with volumes that
exceed 50,000 vehicles per day within the City (LUCE EIR Section 4.3 Air Quality, Impact AQ-2, Long-term). The other
types of TAC sources in the City (existing or proposed under implementation of the LUCE and Zoning Regulations
Update) would be required by law to comply with APCD’s permit process, which would ensure exposure to sensitive
receptors to TACS to be within acceptable levels.
The LUCE EIR determined that “Implementation of the LUCE Update would not result in the exposure of sensitive
receptors to substantial sources of local carbon monoxide concentrations, odors, or TACs” (LUCE EIR Section 4.3 Air
Quality, Impact AQ-2, Long-term).

Proposed Zoning Regulations Update Analysis and Conclusions
Overall, implementation of the Zoning Regulations Update would involve operation of development projects that generate
long‐term emissions of criteria air pollutants and ozone precursors, consistent with the LUCE (refer to LUCE EIR Section
4.3 Air Quality, Impact AQ-2, Long-term, under discussion b). Implementation of the Zoning Regulations Update would
not result in the exposure of sensitive receptors to substantial sources of local carbon monoxide concentrations or TACs, as
development would occur in the areas assessed in the LUCE EIR.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable regulations, performance standards,
and design standards as required by the City’s Municipal Code, the APCD, and CARB. Therefore, the proposed Project
would not result in a significant air quality impact not examined or adequately addressed in the LUCE EIR, and impacts
would be less than significant.
Conclusion. The proposed Project would make revisions, additions, corrections and clarifications to various sections of the
Zoning Regulations to ensure consistency and successful implementation of the LUCE. The proposed Zoning Regulations
Update would not allow new urban development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new air quality impacts that have not been previously examined or adequately addressed in
LUCE EIR Section 4.3 Air Quality.
e) LUCE EIR Conclusion
As noted in the LUCE EIR, City of San Luis Obispo General Plan Update Background Report (6.3), existing potential odor
sources in the city include a wastewater treatment plant (35 Prado Road San Luis Obispo, CA 93401, and several
automotive businesses. No other major odor sources are identified. Other minor sources of odor associated with typical
land uses located in commercial and industrial areas in urban communities are currently present in the city, such as
restaurants, auto repair facilities, gasoline stations, manufacturing plants, and other similar uses. The LUCE EIR
determined that “Implementation of the LUCE Update would not result in the exposure of sensitive receptors to substantial
sources of local carbon monoxide concentrations, odors, or TACs” (LUCE EIR Section 4.3 Air Quality, Impact AQ-2,
Long-term).
Proposed Zoning Regulations Update Analysis and Conclusions
There are no major new sources of odor that are proposed or designated in the LUCE or Zoning Regulations Update.
Various commercial and industrial land uses could be developed pursuant to the Zoning Regulations Update, but these are
not typically associated with major sources. In addition, implementation of the LUCE and Zoning Regulations Update
would not result in the placement of new sensitive receptors closer to existing sources in comparison to existing conditions,
including underlying land use designations and zoning for uses considered sensitive.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable regulations, performance standards,
and design standards as required by the City’s Municipal Code, the APCD, and CARB. Therefore, the proposed Project
would not result in a significant air quality impact not examined or adequately addressed in the LUCE EIR, and impacts
would be less than significant.
Conclusion. The proposed Project would make revisions, additions, corrections and clarifications to various sections of the
Zoning Regulations to ensure consistency and successful implementation of the LUCE. The proposed Zoning Regulations
Update would not allow new urban development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new air quality impacts that have not been previously examined or adequately addressed in
LUCE EIR Section 4.3 Air Quality.

Evaluation
The urbanized area of the City of San Luis Obispo lies at the convergence of two main geologic features: the Los Osos Valley
which drains westerly into Morro Bay via Los Osos Creek, and the San Luis Valley which drains to the south-southwest into
the Pacific Ocean at Avila Beach via San Luis Obispo Creek. San Luis Obispo, Stenner, Prefumo, and Brizzolara Creeks, and
numerous tributary channels pass through the city, providing important riparian habitat and migration corridors connecting
urbanized areas to less‐developed habitats in the larger LUCE Sphere of Influence (SOI) Planning Subarea surrounding the city.
Much of the LUCE SOI Planning Subarea outside the city limits consist of open rangeland grazed year-round, along with
agricultural lands dominated by annual crop rotations and vineyards. A variety of natural habitats and associated plant
communities are present within the LUCE SOI Planning Subarea and support a diverse array of native plants and resident,
migratory, and locally nomadic wildlife species, some of which are considered as rare, threatened, or endangered species.
Serpentine soils and serpentine rock outcrops present within the LUCE SOI Planning Subarea typically support a high
percentage of sensitive or special status plant species due to the unique chemical composition of this volcanic soil. The types
and locations of habitats present are shown on LUCE EIR Section 4.4 Biological Resources, Figure 4.4‐1a Planning Area
Habitat Map and Figure 4.4‐1b City of San Luis Obispo Habitat Map, and listed in LUCE EIR Section 4.4 Biological
Resources, Table 4.4‐1, Habitat Types within the LUCE SOI Planning Subarea. LUCE EIR Section 4.4 Biological Resources,
Table 4.4-1 Natural Habitat Constraints Summary identifies the special-status species associated with each habitat type within
the City. The largest concentrations of natural and native habitats are located in the larger LUCE SOI Planning Subarea outside
the city limits. LUCE EIR Section 4.4, Biological Resources, includes additional descriptions of habitats, vegetation types,
special status plants and animals, and common wildlife and associated wildlife corridors found within the City and the LUCE
SOI.

concern, and 20 special‐status wildlife species with recorded occurrences within a 10‐mile search radius of the LUCE SOI
Planning Subarea. Portions of the northern and eastern LUCE SOI Planning Subarea are located in California red‐legged
frog (CRLF) Critical Habitat Unit SLO‐3—Willow and Toro Creeks to San Luis Obispo. LUCE EIR Section 4.4 Biological
Resources, Figure 4.4‐2 CNDDB Botanical Occurrences within Planning Area and Figure 4.4‐3 CNDDB Wildlife
Occurrences within Planning Area show the CNDDB plant and wildlife special‐status species recorded occurrences within
the LUCE SOI Planning Subarea. LUCE EIR Section 4.4 Biological Resources, Table 4.4‐2 Special Status Plant Species
and Natural Communities of Special Concern in the LUCE SOI Planning Subarea and Figure 4.4‐3 Special Status Wildlife
Species in the LUCE SOI Planning Subarea show the scientific and common names and listing status for the special-status
species present or with potential to occur in the LUCE SOI Planning Subarea. Additional species information is presented
in the LUCE EIR Background Report. Focused biological surveys have not been conducted over the entire LUCE SOI
Planning Subarea, and therefore, additional, previously unidentified species or habitats could also occur. Site‐specific
surveys for any potentially sensitive species and habitats would be necessary to confirm presence/absence within a
particular area prior to any development under the LUCE and Zoning Regulations Update. In addition, development within
the City is subject to compliance with policies and programs that address special-status species and habitats, as identified in
COSE Section 7, Natural Communities.
LUCE EIR Conclusion
Special-status Plants. Development under the LUCE Update has potential to impact special‐status plant species (as defined
in LUCE EIR Section 4.4.1b) present within the LUCE SOI Planning Subarea. Although the majority of special-status
plant species occurrences are located outside the city limits, development within any natural habitat type within the city
limits could have potential to impact special‐status plant species.
As identified in the LUCE EIR, “development consistent with the LUCE Update has the potential to impact special‐status
plant species within the LUCE SOI Planning Subarea. With the incorporation of the proposed and existing City policies,
and the requirements of regulatory and oversight agencies, potential impacts to special‐status plant species are considered
Class III, less than significant” (LUCE EIR Section 4.4 Biological Resources, Impact BIO-3).
Proposed Zoning Regulations Update Analysis and Conclusions
Similar to the analysis of the LUCE, future development under the Zoning Regulations Update will be required to comply
with local, state, and federal laws and policies, and all applicable permitting requirements of the regulatory and oversight
agencies intended to address potential impacts to special‐status plant species. Future projects within or adjacent to known
occurrences of a listed species, or habitat types that have potential to contain special‐status plant species, will undergo
individual project environmental review to ensure protection of special‐status plant species populations. Focused biological
surveys to determine presence/absence and map locations of special‐status plant species occurrences would be required
prior to any ground disturbing activity. Impacts to special‐status plant species may require consultation with the California
Department of Fish and Wildlife (CDFW) and U.S. Fish and Wildlife Service (USFWS), and mitigation would be required
per city policy and state and federal regulations to offset any impacts associated with individual project development.
Development under the proposed Zoning Regulations Update has potential to impact special‐status plant species within the
LUCE SOI Planning Subarea. However, with adherence to the existing City policies and state and federal regulatory
requirements, impacts would be addressed through either avoidance of the resource based on detailed site‐specific
biological studies, or through the detailed mitigation requirements for the protection of plant species that occur on a given
site. Implementation of proposed and existing local policies, as well as compliance with State and Federal laws and policies
and the requirements of regulatory and oversight agencies as appropriate, and reliance on establishment of project‐specific
mitigation measures where appropriate would reduce potential impacts to a less than significant level.

wildlife species (as identified in LUCE EIR Section 4.4.1b). While the majority of special‐status wildlife species
occurrences are located outside the city limits, development within grasslands, wetland, riparian, and forest/grove habitats
within the city limits would have potential to impact special‐status wildlife. Projects within or adjacent to known
occurrences of listed species, or habitat types that have potential to contain one or more special‐status wildlife species,
would undergo individual project environmental review to ensure protection of those species. The existing General Plan
requires focused biological surveys to determine presence/absence and map locations of special‐status wildlife species
occurrences prior to any habitat disturbance. Impacts to special‐status wildlife species may require consultation with the
CDFW, USFWS, and National Oceanic and Atmospheric Administration (NOAA) Fisheries, and mitigation would be
required to offset specific project impacts. Implementation of LUE and COSE policies, as well as compliance with local,
State and Federal laws and policies and the requirements of regulatory and oversight agencies as appropriate, and reliance
on establishment of project‐specific mitigation measures where appropriate would reduce potential impacts to a less than
significant level.
As identified in the LUCE EIR, “development consistent with the LUCE Update has potential to impact special‐status
wildlife species within the LUCE SOI Planning Subarea. With the incorporation of the proposed and existing City policies,
and the requirements of regulatory and oversight agencies, potential impacts to special‐status wildlife species are
considered Class III, less than significant” (LUCE EIR Section 4.3 Biological Resources, Impact BIO‐4).
Proposed Zoning Regulations Update Analysis and Conclusions
Similar to the analysis of the LUCE, future development pursuant to the Zoning Regulations Update will be required to
comply with local, state, and federal laws and policies, and all applicable permitting requirements of the regulatory and
oversight agencies intended to address potential impacts to special‐status wildlife species. Based on compliance with the
LUCE and COSE, and adherence to the existing City regulations and state and federal regulatory requirements, future
development projects with the potential to impact special‐status wildlife will be required to fully study project site
resources, avoid disturbance of identified wildlife and their habitat and mitigate any impacts in accordance with qualified
professionals under the authority of the jurisdictional agencies. Implementation of proposed and existing local policies, as
well as compliance with state and federal laws and policies and the requirements of regulatory and oversight agencies as
appropriate, and reliance on establishment of project‐specific mitigation measures where appropriate would reduce
potential impacts to a less than significant level.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable policies, regulations, performance
standards, and design standards as required by the City’s Municipal Code, the General Plan, and CEQA. Therefore, the
proposed Project would not result in any significant impacts to special-status plants and wildlife not examined or
adequately addressed in the LUCE EIR, and impacts would be less than significant.
Conclusion. The proposed Project would make revisions, additions, corrections and clarifications to various sections of the
Zoning Regulations to ensure consistency and successful implementation of the LUCE. The proposed Zoning Regulations
Update would not allow new development in areas where such development is prohibited under the LUCE. Therefore,
there would be no new impacts to special-status plant and wildlife species that have not been previously examined or
adequately addressed in LUCE EIR Section 4.4 Biological Resources.
b), c) LUCE EIR Conclusion
Riparian and wetland habitats include streams, lakes, ponds, and associated natural vegetation adapted to increased soil
moisture, and have a high potential to contain special status plant and animal species. Major examples in the City include
San Luis Obispo, Stenner, Brizzolara, and Prefumo Creeks, Laguna Lake, and many smaller tributary drainages. These
features and habitats pass through and border all other habitat types present in the LUCE SOI Planning Subarea and could
be significantly impacted by implementation of the LUCE. All development in the City is subject to creek setback
requirements and performance standards identified in the Zoning Regulations. Development under the LUCE Update has
potential to impact four habitat types listed as Natural Communities of Special Concern by the CDFW, Serpentine

Bunchgrass, Northern Interior Cypress Stand, Central Maritime Chaparral, and Coastal and Valley Freshwater Marsh, that
have high potential to support special‐status plant and wildlife species (refer to LUCE EIR Section 4.4 Biological
Resources, Table 4.4‐2 Special Status Plant Species and Natural Communities of Special Concern in the LUCE SOI
Planning Subarea). In addition, riparian, vernal pool, oak woodland, and native perennial grassland habitats present within
the LUCE SOI Planning Subarea are considered sensitive by the CDFW and other regulatory agencies and could be
impacted by future development (also see LUCE EIR Section 4.4 Biological Resources, Table 4.4‐4 Natural Habitat
Constraints Summary).
The LUCE EIR concluded that “development consistent with the LUCE Update has potential to impact four Natural
Communities of Special Concern present within the LUCE SOI Planning Subarea including Serpentine Bunchgrass,
Northern Interior Cypress Stand, Central Maritime Chaparral, and Coastal and Valley Freshwater Marsh. With the
incorporation of the proposed and existing City policies, and the requirements of regulatory and oversight agencies,
potential impacts to sensitive habitats are considered Class III, less than significant” (LUCE EIR Section 4.4 Biological
Resources, Impact BIO‐2).
Proposed Zoning Regulations Update Analysis and Conclusions
Similar to the analysis in the LUCE EIR, potential near‐term and long‐term impacts resulting from implementation of the
Zoning Regulations Update, including development in or near sensitive or jurisdictional areas may include loss of habitat
and the introduction or increase of human presence. Specific impacts due to development include the disruption of patterns
of habitat use, displacement of individuals, disruption of breeding habits, disruption and barriers to wildlife movements,
increased mortality of wildlife species and in turn less prey, night lighting, and reduction of available habitat in general.
The level of intensity of impacts related to human presence would depend upon the habitat disturbed and level of build out
within these developable areas and adjacent habitat areas. COSE Policy 7.3 requires that projects within or adjacent to
known occurrences of Natural Communities of Special Concern, or in areas that have potential to contain one or more of
these habitats, would be expected to have a site-specific biology report prepared and undergo individual project
environmental review to determine the location, extent, and proposed impact to those habitats. These project‐level
biological surveys to map Special Concern or sensitive habitat boundaries, and to determine presence/absence of
special‐status wildlife and plant species would be required prior to any ground disturbing activity. Any impacts to these
habitats would require permits and/or authorization from local, state and federal regulatory agencies, including the City of
San Luis Obispo, CDFW, Regional Water Quality Control Board (RWQCB), USFWS, NOAA Fisheries, and U.S. Army
Corps of Engineers (USACE), and site‐specific mitigation would be required to offset impacts associated with project
development. Similar to the conclusions in the LUCE EIR, based on compliance with LUCE and COSE policies, and the
regulatory framework governing sensitive habitats and associated plant and wildlife species, potential impacts to Special
Concern or sensitive habitats within the LUCE SOI Planning Subarea are considered potentially significant but mitigable.
Future development consistent with the LUCE and Zoning Regulations Update will be required to comply with local, state,
and federal laws and policies, and all applicable permitting requirements of the regulatory and oversight agencies intended
to address potential impacts to natural communities of special concern. Individual development will be required to undergo
separate environmental review, which may result in specific impacts that require project specific mitigation consistent with
LUE and COSE policies. Potentially significant impacts that may occur as a result of implementation of the proposed
Project would be reduced through goals, policies and programs that require either the protection and avoidance of protected
resources prior to proposed development, or though the required mitigation of impacts to protected resources.
Implementation of existing General Plan policies, as well as compliance with State and Federal laws and policies and the
requirements of regulatory and oversight agencies as appropriate, and reliance on establishment of project‐specific
mitigation measures where appropriate would reduce potential impacts to a less than significant level.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable policies, regulations, performance
standards, and design standards as required by the City’s Municipal Code and General Plan. Therefore, the proposed
Project would not result in any significant impacts to riparian, wetland, and other sensitive communities and habitats not

examined or adequately addressed in the LUCE EIR, and impacts would be less than significant.
Conclusion. The proposed Project would make revisions, additions, corrections and clarifications to various sections of the
Zoning Regulations to ensure consistency and successful implementation of the LUCE. The proposed Zoning Regulations
Update would maintain and clarify required creek setback regulations and would not allow new development in areas
where such development is prohibited under the LUCE. Therefore, there would be no new impacts to riparian, wetland, and
other sensitive communities and habitats that have not been previously examined or adequately addressed in LUCE EIR
Section 4.4 Biological Resources.
e) LUCE EIR Conclusion
As identified in the LUCE EIR, future development has the potential to impact common natural habitat types, common
wildlife species, species of local concern, and associated wildlife corridors present within the LUCE SOI Planning Subarea.
The LUCE EIR determined that “development under the LUCE Update has potential to impact common habitat types
including non‐native annual grasslands and disturbed/ruderal areas that provide habitat for common wildlife and plant
species. With the incorporation of the proposed LUCE Update policies and existing governing policies, potential impacts to
these common habitats are considered Class III, less than significant” (LUCE EIR Section 4.4 Biological Resources,
Impact BIO‐1). The LUCE EIR also determined that “development consistent with the LUCE Update has potential to
impact common wildlife species and species of local concern within the LUCE SOI Planning Subarea. With the
incorporation of the proposed and existing City policies, and the requirements of regulatory and oversight agencies,
potential impacts to common and species of local concern are considered Class III, less than significant” (LUCE EIR
Section 4.4, Biological Resources, Impact BIO‐5).
Proposed Zoning Regulations Update Analysis and Conclusions
Similar to the analysis in the LUCE EIR, development under the Zoning Regulations Update has potential to impact
common wildlife species and species of local concern through habitat loss, migration corridor loss from the barrier effect of
new roads and developed areas, and increased noise, traffic, lighting, and human presence. Development within or adjacent
to any natural habitat type within the project area would have potential to impact these wildlife species. Projects within or
adjacent to habitat types that have potential to contain common wildlife species would undergo individual project
environmental review to ensure that avoidance and minimization measures are included in design, construction, and
ongoing uses. Project‐specific mitigation measures may be required to offset impacts to common wildlife species and
species of local concern associated with future project development consistent with the LUCE and Zoning Regulations
Update. Future development will also be required to comply with local, state, and federal laws and policies, and all
applicable permitting requirements of the regulatory and oversight agencies intended to address potential impacts to
common wildlife and species of local concern. Individual development will be required to undergo separate environmental
review, which may result in specific impacts that require project specific mitigation consistent with these policies.
Based on compliance with existing LUCE and COSE policies and programs, adherence to the existing City regulations and
state and federal regulatory requirements, future development projects with the potential to impact common and locally
important wildlife will be required to fully study project site resources, avoid disturbance of identified wildlife and their
habitat and mitigate any impacts in accordance with qualified professionals under the authority of the jurisdictional
agencies. Implementation of proposed and existing local policies, as well as compliance with state and federal laws and
policies and the requirements of regulatory and oversight agencies as appropriate, and reliance on establishment of
project‐specific mitigation measures where appropriate would reduce potential impacts to a less than significant level.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable policies, regulations, performance
standards, and design standards as required by the City’s Municipal Code and General Plan. Therefore, the proposed
Project would not result in any significant impacts to fish and wildlife, and associated habitats and habitat corridors, not
examined or adequately addressed in the LUCE EIR, and impacts would be less than significant.

Conclusion. The proposed Project would make revisions, additions, corrections and clarifications to various sections of the
Zoning Regulations to ensure consistency and successful implementation of the LUCE. The proposed Zoning Regulations
Update would maintain and clarify required creek setback regulations and would not allow new development in areas
where such development is prohibited under the LUCE. Therefore, there would be no new impacts to fish and wildlife, and
associated habitats and habitat corridors that have not been previously examined or adequately addressed in LUCE EIR
Section 4.4 Biological Resources.
e), f) Development within the City is subject to existing policies and programs identified in the General Plan, including the LUE
and COSE, and the City’s Municipal Code, including Chapter 12.24, Tree Regulations. The proposed Project would not
modify or conflict with these existing policies or regulations, and include clarifications to regulations specific to hillside
development and development on slopes exceeding 16 percent, which would further protect natural resources found on
hillside locations by implementing the goals of the COSE, including:
1. To protect and preserve scenic hillside areas and natural features such as the volcanic Morros, ridge lines, plant
communities, rock outcroppings and steep slope areas that function as landscape backdrops for the community;
2. To avoid encroachment into sensitive habitats or unique resources as defined in the Conservation and Open Space
Element;
3. To protect the health, safety and welfare of community residents by directing development away from areas with
hazards such as landslides, wildland fires, flooding and erosion; and
4. To protect the City’s scenic setting.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land use that
occur pursuant to the proposed Project would be required to conform to all applicable regulations, performance standards
and design standards of the Zoning Regulations as updated, the Tree Regulations, the LUCE, and the COSE that address
natural resources. Pursuant to CEQA, future new land uses that occur pursuant to the proposed Zoning Regulations Update
would be subject to their own environmental review on a project-by-project basis to assess impacts on natural resources.
Therefore, the proposed project would not conflict with any local policies or ordinances protecting biological resources.
Impacts would be less than significant.
Conclusion. The proposed Project would make revisions, additions, corrections and clarifications to various sections of the
Zoning Regulations to ensure consistency and successful implementation of the LUCE and other elements of the General
Plan, including the COSE. Therefore, there would be no new impacts that have not been previously examined or
adequately addressed in LUCE EIR Section 4.4 Biological Resources.

The City of San Luis Obispo is located within the area historically occupied by the Obispeño Chumash, the northernmost of the
Chumash people of California. The San Luis Obispo area became colonialized by the Spanish Incursion initially in 1542, with

the first official settlement on Chumash Territory occurring in 1772, when the Mission San Luis Obispo de Tolosa was
established. Since this period, a timeline of San Luis Obispo modern occupation has been broken down into multiple smaller
eras, the first of which being the Spanish Incursion—the Mission Era lasted from 1772‐1850. In 1822 California became a
Mexican Territory, and the mission lands gradually became private ranchos via new Mexican land grants. In 1834, the
proclamation for secularization was issued, and the Mission was effectively disbanded. By that time, “missionization,” disease,
and destruction of the native subsistence base had decimated the Chumash and their culture. Immigrants began coming to the
state in the 1850’s, during the Early Settlement Era (lasting from 1850‐1875), and by the 1870’s (after the earliest arrivals of
Chinese immigrants in 1969), a Chinatown district had been established in the downtown area near Palm and Morro Street. By
1875, 2,500 residents were documented in a 4‐square mile area around what is not the City of San Luis Obispo. Population
growth and advancements in technology continued to occur during this Industrial Era (1875‐1900). The period from
1900‐1945, is said to commence exponential rates of population growth for the area. The last era of growth is said to have
lasted from 1945 to the present. Many of the residential subdivisions in the Foothill and Laguna Lake area were developed
between 1945 and 1970 and the city’s population increased by 53% during this time. As new projects are proposed, the City
continues to make strong efforts in conserving the natural and historical resources and character that lie within the community
so as to maintain a connection to the past.
Regarding paleontological resources, the only fossil resources likely to occur in the City are of Quaternary (Pleistocene) age.
The Quaternary is the most recent of the three Periods of the Cenozoic Era in the geologic time scale. It follows the Tertiary
Period, spanning from about 2,588,000 years ago to the present. The LUCE EIR notes three reported vertebrate localities along
the coast within nine miles of the city, which include assemblages of the mammals Equus sp. and E. occidentalis (horse);
Camelops sp. and C. hesternus (camel); Bison antiquus and B. latifrons (bison), and Mammut americanum (mammoth).
This information, and additional background is provided in LUCE EIR Section 4.5 Cultural Resources.
a) A historical resource is defined in Section 15064.5(a) of the CEQA Guidelines as a resource listed in or eligible for listing
in the California Register of Historical Resources; a resource included in a local register of historical resources; or any
object, building, structure, site, area, place, record or manuscript determined to be historically significant or significant in
the architectural, engineering, scientific, economic, agricultural, educational, social, political, military or cultural annals of
California. Generally, a resource is considered to be “historically significant” if it meets one of the following criteria:
Is associated with events that have made a significant contribution to the broad patterns of California’s history and
cultural heritage;
Is associated with the lives of persons important in our past;
Embodies the distinctive characteristics of a type, period, region or method of construction, or represents the work of
an important creative individual, or possesses high artistic values; or
Has yielded, or may be likely to yield, information important in prehistory or history.
Resources listed in or determined eligible for the California Register, included in a local register, or identified as
significant in a historic resource survey are also considered historical resources under CEQA.
Historic resources in the City are subject to the policies and regulations contained in the General Plan, Historic
Preservation Ordinance, Historic Preservation Program Guidelines. These policies and regulations also identify the review
process for actions proposed within historical districts (see LUCE EIR Section 4.5, Cultural Resources Figure 4.5-1 City of
San Luis Obispo Historical Districts) and on properties that contain Master List and Contributing Historic Resources.
LUCE EIR Conclusion
The LUCE EIR concludes that “development allowed by the LUCE update could cause a substantial adverse change in the
significance of a historical resource which is either listed or eligible for listing on the National Register of Historic Places,
the California Register of Historic Resources, or a local register of historic resources. This impact is considered to be Class
II, significant but mitigable” (LUCE EIR Section 4.5, Cultural Resources Impact CR‐1).

Proposed Zoning Regulations Update Analysis and Conclusions
Similar to the analysis in the LUCE EIR, intensification of land uses anticipated to occur in certain areas of the city under
the Zoning Regulations Update could have an adverse effect on historic structures by damaging or destroying historical
buildings or structures, diminishing the integrity of the context and setting of individual properties, or diminishing the
integrity of the historical district. The loss of historic buildings or new developments within the existing historic districts
that could impact historical resources is considered potentially significant. However, the policies and programs identified in
the LUCE and COSE, the City’s Historic Preservation Ordinance, Historic Preservation Program Guidelines, Historic
Context Statement, Archaeological Resource Preservation Program Guidelines, the City‐designated Cultural Heritage
Committee (CHC) policies and guidelines, and compliance with CEQA directly address this impact.
Development facilitated under the Zoning Regulations Update will have the potential to result in impacts to historical
resources. These changes are subject to the policies and regulations identified above, which target historical resource
protection. Compliance with existing regulations, standards, and guidelines, in addition to project review by the Cultural
Heritage Committee, will help govern development and redevelopment that may occur during the lifetime of the LUCE and
proposed Zoning Regulations. All of these plans and documents work together to protect San Luis Obispo’s historical
resources and are a means to retain the community character and history, while providing enhancements in certain areas of
the city. Impacts will be less than significant with implementation of applicable policies and regulations. Individual
development pursuant to the Zoning Regulations Update will be required to undergo separate environmental review, which
may result in specific impacts that require project specific mitigation consistent with these policies. Based on compliance
with existing City policies, programs, and regulations related to historic resources, impacts can be avoided through the
protection of known historic structures and through the study of potentially historic resources prior to construction and
through measures required to preserve significant resources, which will reduce impacts to less than significant levels.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development, and would continue to
provide for the protection of the City’s historic resources. The proposed Zoning Regulations Update would not make any
changes to the Historic Preservation Ordinance and would not allow new development in areas where such development is
prohibited under the LUCE. Therefore, impacts would be less than significant.
Conclusion. The proposed Project would make revisions, additions, corrections and clarifications to various sections of the
Zoning Regulations to ensure consistency and successful implementation of the LUCE. Future land use that occur pursuant
to the proposed Project would be required to conform to all applicable regulations of the Zoning Regulations, as updated,
the LUCE and COSE, the Historic Preservation Ordinance, and Historic Preservation Program Guidelines, all of which
address historical resources. Notwithstanding existing provisions that aim to protect existing historic resources, demolition
or alteration of a historical resource on a parcel in the City could conceivably occur as a result of individual development
projects. Pursuant to CEQA, future new land uses that occur pursuant to the proposed Zoning Regulations Update would
be subject to their own environmental review on a project-by-project basis to assess impacts on historical resources.
Therefore, the proposed Project would not result in a significant impact on historical resources not examined or adequately
addressed in LUCE EIR Section 4.5, Cultural Resources.
b), c), d) LUCE EIR Conclusion
As documented in the LUCE EIR, proposed development under the policies proposed under the LUCE could impact areas
that contain previously identified and previously unidentified archaeological and paleontological resources such as sites
containing Native American artifacts, burial sites/human remains, buildings or structures dating from the identified Mission
era, or early urbanization periods. The degree of such impacts is dependent upon the proximity of new construction or
development to previously identified archaeological and paleontological sites, and also dependent upon the level of
development near previously unidentified resources. The LUCE encourages infill development in areas already within the
city, which would be facilitated by the updates proposed for the Zoning Regulations. Infill development typically reduces
the pressure to develop on the edges of the city, which could have impacts on previously unidentified archaeological and
paleontological resources. However, due to the nature of new developments, some future structures may interfere or
coincide with previously unidentified archaeological and paleontological resources. If archaeological and paleontological

resources are discovered, existing codes and policies stipulate treatment methods for evaluation and treatment of the
resources. Implementation of these policies on a project‐by‐project basis would require the preparation of site‐specific
archaeological and paleontological studies in areas of potential sensitivity as well as mitigation of impacts to any identified
resources. In addition, implementation of the City’s Archaeological Preservation Program Guidelines is intended to
incorporate archaeological resource preservation during the early stages of project planning and design. Property owners,
developers, builders, design professionals and others involved in public or private development can use these guidelines to
anticipate City concerns, protect important cultural resources, and to design their projects so as to avoid delays during
development review and construction.
The LUCE EIR concluded that “development facilitated by Land Use and Circulation Element Update could adversely
affect identified and previously unidentified archaeological and paleontological resources. This includes potential
disturbance of human remains. General Plan policies would ensure that such impacts are addressed on a case‐by‐case basis.
Impacts would be considered Class III, less than significant” (LUCE EIR Section 4.5, Cultural Resources, Impact CR-2).
In addition, the LUCE EIR determined that “development facilitated by the LUCE Update could…result in the loss of a
unique geologic feature. However, compliance of future development projects with…adopted General Plan policies would
ensure that resulting impacts are Class III, less than significant” (LUCE EIR, Section 4.6 Geology and Soils, Impact GEO-
3).
Proposed Zoning Regulations Update Analysis and Conclusions
Similar to the analysis in the LUCE EIR, development facilitated under the Zoning Regulations Update will result in
impacts to archaeological and paleontological resources and undiscovered human remains. These changes are subject to the
policies and regulations included in the existing and proposed policies that target historical resource protection. The City
Historic Preservation Ordinance, Historic Preservation Program Guidelines, Historic Context Statement, Archaeological
Resource Preservation Program Guidelines and review by the Cultural Heritage Committee will govern development and
redevelopment that may occur during the lifetime of the LUCE and Zoning Regulations Update. All of these plans and
documents work together to protect San Luis Obispo’s archaeological and paleontological resources and are a means to
retain the community character and history, while providing enhancements in certain areas of the city. Impacts will be less
than significant with implementation of Applicable policies and regulations. Individual development will be required to
undergo separate environmental review, which may result in specific impacts that require project specific mitigation
consistent with existing policies and regulations.
Excavation of land, or development on previously undisturbed lands, may affect paleontological resources. COSE Policy
3.5.1 (Archaeological resource protection) requires protection of both archaeological and paleontological resources through
compliance with the City’s Archeological Resource Preservation Guidelines. This linkage through policy ensures that other
COSE policies such as 3.5.3 that prohibits non‐development related destruction of resources; and, 3.5.12 that protects
resources with open space designations; and, 3.6.5 through 3.6.7 regarding the treatment and curation of resources, would
apply to paleontological resources. The existence of resources would be determined during the exploration of a
development site at the time of a development proposal as required by COSE Policy 3.5.1. With implementation of the
existing COSE policies and compliance with state law, the impact to paleontological resources is considered less than
significant.
Development facilitated by the Zoning Regulations Update could adversely affect identified and previously unidentified
archaeological and paleontological resources, including the potential disturbance of human remains. However, adherence
to existing Federal, State and City policies and programs discussed above will address these impacts by requiring the study
of site-specific resources, identification of significant resources present within a given project site, requirements to avoid
significant resources and requirements to mitigate any impacts to these resources through project design, monitoring and
Native American consultation. As such, impacts are considered less than significant.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land use that
occur pursuant to the proposed Project would be required to conform to federal, State, and local guidelines and

requirements that address the discovery of archaeological and paleontological resources. Pursuant to CEQA, future new
land uses that occur pursuant to the proposed Zoning Regulations Update would be subject to their own environmental
review on a project-by-project basis to assess impacts on archaeological resources. Therefore, the proposed Project would
not significantly disturb archaeological or paleontological resources. Impacts would be less than significant.
Conclusion. The proposed Project would make revisions, additions, corrections and clarifications to various sections of the
Zoning Regulations to ensure consistency and successful implementation of the LUCE. The proposed Zoning Regulations
Update would not allow new development in areas where such development is prohibited under the LUCE. Future
development that occurs pursuant to the proposed Project would be required to conform to all applicable regulations of the
Zoning Regulations, as updated, the LUCE and COSE, the Historic Preservation Ordinance, Historic Preservation Program
Guidelines, and Archaeological Resource Preservation Program Guidelines, which address historical, archaeological, and
paleontological resources. In addition, future actions are subject to State CEQA Guidelines Section 15064.5 relating to the
discovery of human remains Therefore, there would be no new impacts that have not been previously examined or
adequately addressed in LUCE EIR Section 4.5, Cultural Resources.

Evaluation
San Luis Obispo County lies within the southern Coast Range Geomorphic Province, which lies between the Central Valley of
California and the Pacific Ocean and extends from Oregon to northern Santa Barbara County. The Coast Range province is
structurally complex and is comprised of sub‐parallel northwest‐southeast trending faults, folds, and mountain ranges. The most
distinctive geomorphological feature of the San Luis Obispo area is the series of Tertiary aged volcanic plugs (remnants of
volcanoes) which extend from the City of San Luis Obispo northwesterly to Morro Bay. Hollister Peak, Bishop Peak, Cerro San
Luis Obispo, Islay Hill, and Morro Rock are all comprised of these volcanic plugs. There are over 21 major and minor peaks in
the Morros, but there are nine major peaks, hence the name commonly used, “The Nine Sisters”. The nine major peaks are:
Morro Rock, Black Hill, Cabrillo Peak, Hollister Peak, Cerro Romauldo, Chumash Peak, Bishop Peak, Cerro San Luis Obispo,
and Islay Hill. The Nine Sisters form a divider between the Los Osos Valley and Chorro Valley, covering approximately 40
square miles.

Seismicity and Ground Shaking. Faults produce ground shaking and/or surface rupture. Seismically induced ground shaking
covers a wide area and is greatly influenced by the distance of the site to the seismic source, soil conditions, and depth to
groundwater. Surface rupture is limited to very near the fault. Other hazards associated with seismically induced ground
shaking include earthquake‐triggered landslides, liquefaction, and tsunamis. The predominant northwest‐southeast trending
structures of the Coast Range Province are related to the San Andreas Fault Transform Boundary. Other faults in the San Luis
Obispo area that are considered active or potentially active include the San Juan Fault, the East and West Huasna Faults, the
Nacimiento Fault Zone, the Oceano Fault, the Oceanic Fault, Cambria Fault, the Edna Fault, the Hosgri Fault, and the Los Osos
Fault. The East and West Huasna Faults, the Nacimiento Fault Zone, the Cambria Fault, and the Edna Fault have not yet been
officially classified by the California Division of Mines and Geology (LUCE EIR Section 4.6, Geology and Soils). As depicted
in LUCE EIR Section 4.6 Geology and Soils, Figure 4.6‐1 Earthquake Faults – Regional Area and Figure 4.6.2 Earthquake
Faults – Local Area, the City is located in a seismically active area. Local active and potentially active faults are shown on
these figures, and represent seismic hazards related to surface displacement and seismically induced ground acceleration. These
faults are described in detail in LUCE EIR Section 4.6 Geology and Soils.
Liquefaction Hazards. Liquefaction is defined as the transformation of a granular material from a solid state to a liquefied state
as a consequence of increased pore water pressure. As a result, structures built on this material can sink into the alluvium,
buried structures may rise to the surface or materials on sloped surfaces may run downhill. Other effects of liquefaction include
lateral spread, flow failures, ground oscillations, and loss of bearing strength. The soils in the San Luis Obispo area that are
most susceptible to ground shaking, and which contain shallow ground water, are the ones most likely to have a potential for
settlement and or liquefaction (refer to LUCE EIR Section 4.6 Geology and Soils, Figure 4.6‐3 Seismic and Landslide
Hazards). The actual risk of settlement or liquefaction is identified by investigation of specific sites, including subsurface
sampling, by qualified professionals. Previous investigations have found that the risk of settlement for new construction can be
reduced to an acceptable level through careful site preparation and proper foundation design, and that the actual risk of
liquefaction is low.
Landslide Hazards. Landslides occur when the underlying support can no longer maintain the load of material above it, causing
a slope failure. Ground shaking and landslide hazards are mapped by the City and are shown in LUCE EIR Section 4.6 Geology
and Soils, Figure 4.6‐3 Seismic and Landslide Hazards. Much of the development in San Luis Obispo is in valleys, where there
is low potential for slope instability; however, the city contains extensive hillsides. Several are underlain by the rocks of the
Franciscan group, which is a source of significant slope instability. The actual risk of slope instability is identified by
investigation of specific sites, including subsurface sampling, by qualified professionals. The California Building Code (CBC)
and City Municipal Code require site‐specific investigations and design proposals by qualified professionals in areas that are
susceptible to slope instability and landslides.
Other Hazards. Differential settlement is the downward movement of the land surface resulting from the compression of void
space in underlying soils. Portions of the city have been identified as possibly being underlain by soft organic soils, resulting in
a high potential for settlement. Other potential geologic hazards in the City include expansive soils, and subsidence, which
occurs where underlying geologic materials (typically loosely consolidated surficial silt, sand, and gravel) undergo a change
from looser to tighter compaction, and as a result, the ground surface subsides (lowers) (refer to LUCE EIR Section 4.6
Geology and Soils, Table 4.6-1 City of San Luis Obispo Soil Properties).
a) The City is located in Seismic Zone 4, the highest level of potential earthquake threat in the State of California. City
General Plan Safety Element Figure 3, Earthquake Faults – Local Area shows mapped and inferred faults in the San Luis
Obispo area, including the Los Osos Fault, which is identified under the California Alquist Priolo Fault Hazards Act.
LUCE EIR Conclusion
The LUCE EIR concluded that “new development under the LUCE Update could be susceptible to impacts from future
seismic events, creating the potential for structural damage or health and safety risks. However, compliance with required
building codes and implementation of General Plan polices would result in a Class III, less than significant impact” (LUCE

EIR, Section 4.6 Geology and Soils, Impact GEO-1).
Proposed Zoning Regulations Update Analysis and Conclusions
Consistent with the analysis in the LUCE EIR, no hazards related to fault rupture area are expected to occur as a result of
implementation of the proposed Zoning Regulations Update because no historically active, active or potentially active
faults are located within or in the immediate vicinity of the city. However, regional faults that could result in strong
groundshaking including the San Andreas, San Juan Fault, the East and West Huasna Faults, the Nacimiento Fault Zone,
the Oceano Fault, the Oceanic Fault, Cambria Fault, the Edna Fault, the Hosgri Fault, and the Los Osos Fault. The range of
maximum probable magnitudes for earthquakes emanating from these faults ranges from 6.5 to 7.8, which would affect
existing and future development. Based on compliance with required building codes and the City’s General Plan, impacts
would be less than significant.
LUCE EIR Conclusion
Regarding liquefaction, the LUCE EIR concluded that “future seismic events could result in liquefaction of soils near San
Luis Obispo Creek, Prefumo Creek and other low‐lying areas. Development in these areas could be subject to liquefaction
hazards. The compliance of future development projects with the California Building Code (CBC) and General Plan
policies would result in Class III, less than significant impacts” (LUCE EIR, Section 4.6, Geology and Soils Impact
GEO‐2).
Proposed Zoning Regulations Update Analysis and Conclusions
Implementation of the proposed Zoning Regulations Update would facilitate the development and redevelopment of lands
within the City. Areas near San Luis Obispo Creek, Prefumo Creek, and other low-lying areas are susceptible to high
groundwater occurrences and most of the existing City has high liquefaction potential (refer to LUCE EIR Section 4.6
Geology and Soils, Figure 5 Groundshaking & Landslide Hazards). Based on compliance with required building codes and
the City’s General Plan, impacts would be less than significant.
LUCE EIR Conclusion
The LUCE EIR notes that build-out in areas that exhibit landslide hazards would have the potential to result in significant
impacts related to slope instability. The City requires the completion of detailed soils reports and ensures that the project
design follows the recommendation in the report. The LUCE EIR concluded that “steep slopes outside of the existing city
limits present potential on‐ or off‐site landslide hazards. In addition to human safety impacts, a landslide has the potential
to damage or destroy structures, roadways and other improvements as well as to deflect and block drainage channels,
causing further damage and erosion, including loss of topsoil. The compliance of future development projects with the
California Building Code (CBC) and General Plan policies would result in Class III, less than significant impacts” (LUCE
EIR Section 4.6 Geology and Soils, Impact GEO-4).
Proposed Zoning Regulations Update Analysis and Conclusions
Implementation of the proposed Zoning Regulations Update would facilitate the development and redevelopment of lands
within the City, and hillside areas identified for future annexation. Consistent with the LUCE EIR, future development may
be subject to direct and indirect impacts related to landslide hazards. Based on compliance with required building codes
and the City’s General Plan, impacts would be less than significant.
The existing General Plan includes several policies that are intended to minimize potential impacts due to seismicity
including: LUE Policy 6.4 Hillside Policies; and Safety Element Policies 4.5 Avoiding Faults, 4.6 Avoiding Slope
Instability, and 4.7 Avoiding Liquefaction Hazards. In addition, the proposed Project includes updated hillside
development standards, which are proposed to implement goals of the COSE, including protection of the “health, safety

and welfare of community residents by directing development away from areas with hazards such as landslides, wildland
fires, flooding and erosion” (refer to Article 3, Hillside Development Standards). The proposed Hillside Development
Standards chapter includes standards requiring that “each structure shall be located in the most accessible, least visually
prominent, most geologically stable portion or portions of the site, at the lowest feasible elevation” and identifies standards
specific to density, proximity to ridgelines, protection of natural slopes 26 percent and greater, and maximum 20 land
disturbance area.
Consistent with the LUCE, implementation of proposed Zoning Regulations Update would facilitate the development and
redevelopment of lands within the City, including areas with potential geologic hazards and soil types conducive to
liquefaction and other stability risks. The potential human health and safety impacts from seismic events would be
mitigated by existing regulations including the CBC. The City periodically updates the version of the CBC in use to keep
current with changes in technology and research regarding building construction and safety. The City’s adoption of the
CBC includes standards for new construction affecting plumbing, electrical, construction unreinforced masonry, wells,
property maintenance. Proper engineering, including compliance with the CBC, the City of San Luis Obispo Municipal
Code, existing policies identified in the LUE and Safety Element, and updated Hillside Development Standards included in
the proposed Project would minimize the risk to life and property and would reduce impacts to less than significant levels.
The proposed Project, by itself, does not propose or authorize any development. Future land uses that occur pursuant to the
proposed Zoning Regulations Update would be required to conform to all General Plan policies, and applicable regulations,
standards and design standards of the CBC, Municipal Code, and Zoning Regulations (Hillside Development Standards)
that address seismic hazards. In addition, the City Municipal Code identifies building requirements to ensure the safety of
life and property through the regulation of development under Title 15 Building and Construction, Section 15.04 –
Construction and Fire Prevention Regulations. This would include the Unreinforced Masonry Hazard Mitigation Program.
Therefore, the proposed Zoning Regulations Update would not expose people or structures to substantial adverse effects
due to seismicity. Impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Zoning Regulations Update would not make changes to the City’s Municipal Code that addresses geologic risks
and building safety. Proposed Hillside Development Standards would further minimize potential seismic risks.
Additionally, the proposed Project would not allow new development in areas where such development is prohibited under
the LUCE. Therefore, there would be no new seismic-related impacts that have not been previously examined or
adequately addressed in LUCE EIR Section 4.6 Geology and Soils).
b) As shown in LUCE EIR Section 4.6 Geology and Soils, Table 4.6-1 City of San Luis Obispo Soil Properties, soils
throughout the City of San Luis Obispo have high to very high erosion potential. Structures and facilities constructed on
highly erosive soils, as well as occupants of the structures, would have the potential to be exposed to hazards related to
erosion. The CBC includes requirements to address soil related hazards. Typical measures included in the CBC
requirements intended to treat hazardous soil conditions involve removal, proper fill selection, and compaction. The City’s
Municipal Code requires implementation of erosion control measures, as approved through the grading and building permit
process (refer to related Municipal Code sections including but not limited to Chapter 15.04 Construction and Fire
Prevention Regulations, Chapter 12.08 Urban Storm Water Quality Management and Discharge Control, Chapter 16.18
General Subdivision Standards, Chapter 16.20 Physical Improvement Standards and Procedures, and Chapter 17.84
Floodplain Management Regulations).
LUCE EIR Conclusion
The LUCE EIR determined that erosion would not be a substantial constraint to development of individual sites provided
that adequate soil and foundation studies are performed prior to construction in accordance with the CBC and existing
General Plan policies. The City requires submittal of erosion control plans and the completion of detailed soils reports and
ensures that the project design follows the recommendation in the report and plan. The LUCE EIR concluded that

“development facilitated by the LUCE Update could occur on soils that have the potential to present natural hazards
(expansive soils, erosive soils, and differential settlement) to structures and roadways. Development could also result in the
loss of a unique geologic feature. However, compliance of future development projects with the California Building Code
and adopted General Plan policies would ensure that resulting impacts are Class III, less than significant” (LUCE EIR
Section 4.6 Geology and Soils, Impact GEO-3).
Proposed Zoning Regulations Update Analysis and Conclusions
Development facilitated by the Zoning Regulations Update could occur on soils that have the potential to present hazards,
including erosive soils, to structures and roadways. Consistent with the LUCE EIR, adherence to the existing City’s
General Plan, the proposed updated Hillside Development Standards, the City of San Luis Obispo Municipal Code, and
implementing proper engineering, including compliance with the California Building Standards, will ensure that potential
impacts related to erosive soils remain less than significant. Individual development will be required to undergo separate
environmental review, which may result in specific impacts that require project specific mitigation consistent with these
policies.
The proposed Project, by itself, does not propose or authorize any development. Future land uses that occur pursuant to the
proposed Zoning Regulations Update would be required to conform to all General Plan policies, and applicable regulations,
standards and design standards of the Municipal Code and Zoning Regulations (Hillside Development Standards) that
address erosion hazards. Therefore, the proposed Zoning Regulations Update would not expose people or structures to
substantial adverse effects due to erosion or loss of topsoil. Impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Zoning Regulations Update would not make changes to the City’s Municipal Code that address erosion and loss
of topsoil. Proposed Hillside Development Standards would further minimize potential erosion risks. Additionally, the
proposed Project would not allow new development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new erosion-related impacts that have not been previously examined or adequately addressed
in LUCE EIR Section 4.6 Geology and Soils.
c) LUCE EIR Conclusion
The LUCE EIR notes that build-out in areas that exhibit landslide and other geologic hazards would have the potential to
result in significant impacts related to slope instability (refer to discussion a, above for additional information regarding
potential seismic hazards). A landslide and other geologic hazards that destabilize slopes have the potential to damage or
destroy structures, roadways and other improvements as well as to deflect and block drainage channels, causing further
damage and erosion, including loss of topsoil. The City requires the completion of detailed soils reports and ensures that
the project design follows the recommendation in the report, to ensure slope stability, pursuant to the City’s Municipal
Code and the CBC.
The LUCE EIR concluded that “steep slopes outside of the existing city limits present potential on‐ or off‐site landslide
hazards. In addition to human safety impacts, a landslide has the potential to damage or destroy structures, roadways and
other improvements as well as to deflect and block drainage channels, causing further damage and erosion, including loss
of topsoil. The compliance of future development projects with the California Building Code (CBC) and General Plan
policies would result in Class III, less than significant impacts” (LUCE EIR Section 4.6 Geology and Soils, Impact GEO-
4).
The General Plan includes several policies that are intended to minimize potential impacts due to slope instability
including: LUE Policy 6.4 Hillside Policies and Safety Element Policies 4.6 Avoiding Slope Instability and 4.7 Avoiding
Liquefaction Hazards. In addition, the proposed Project includes an updated Hillside Development Standards chapter (refer
to proposed Zoning Regulations Update Article 3). In addition, the City Municipal Code identifies building requirements to
ensure the safety of life and property through the regulation of development under Title 15 Building and Construction,

Section 15.04 – Construction and Fire Prevention Regulations. These regulations require detailed soils analysis be prepared
to support the proposed building or subdivision activity. As a result of the analysis, larger footings, soil amendment or
changes in construction methods and/or materials may be required. While design features and engineering solutions cannot
be known until a specific development is proposed for a given site, compliance with the CBC, the City Municipal Code and
General Plan policies will reduce impacts from landslides to less than significant. Individual development will be required
to undergo separate environmental review, which may result in specific impacts that require project specific mitigation
consistent with these policies.
Proposed Zoning Regulations Update Analysis and Conclusions
Similar to the analysis in the LUCE EIR, implementation of the proposed Zoning Regulations Update would facilitate the
development and redevelopment of lands within the city, including areas with potential geologic hazards and soil types
conducive to liquefaction and other stability risks. The potential human health and safety impacts from landslide,
liquefaction, and other slope stability risks would be considered significant; however, new development would conform to
the CBC. Proper engineering, including compliance with the CBC, the City Municipal Code, existing policies identified in
the LUE and Safety Element, and updated Hillside Development Standards included in the proposed Project would
minimize the risk to life and property.
The proposed Project, by itself, does not propose or authorize any development. Future land uses that occur pursuant to the
proposed Zoning Regulations Update would be required to conform to all General Plan policies, and applicable regulations,
standards and design standards of the CBC, Municipal Code, and Zoning Regulations (Hillside Development Standards)
that address slope stability. Based on compliance with existing regulations, potential impacts related to slope instability
would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Zoning Regulations Update would not make changes to the City’s Municipal Code that addresses geologic risks
and building safety. Proposed Hillside Development Standards would further minimize potential seismic risks.
Additionally, the proposed Project would not allow new development in areas where such development is prohibited under
the LUCE. Therefore, there would be no new seismic-related impacts that have not been previously examined or
adequately addressed in LUCE EIR Section 4.6, Geology and Soils.
d) As shown in LUCE EIR Section 4.6 Geology and Soils, Table 4.6‐1 City of San Luis Obispo Soil Properties, several soils
within the City have moderate shrink‐swell potential, and the potential for soil settlement could result in significant impacts
to new development in these areas. The shrink‐swell characteristics of soils can vary widely within short distances,
depending on the relative amount and type of clay.
LUCE EIR Conclusion
The LUCE concluded that “development facilitated by the LUCE Update could occur on soils that have the potential to
present natural hazards (expansive soils, erosive soils, and differential settlement) to structures and roadways. Development
could also result in the loss of a unique geologic feature. However, compliance of future development projects with the
California Building Code and adopted General Plan policies would ensure that resulting impacts are Class III, less than
significant” (LUCE EIR Section 4.6 Geology and Soils, Impact GEO‐3).
Proposed Zoning Regulations Update Analysis and Conclusions
Similar to the analysis in the LUCE EIR, implementation of the proposed Zoning Regulations Update would facilitate the
development and redevelopment of lands within the city, including areas with expansive soils. The CBC includes
requirements to address soil related hazards. Typical measures included in the CBC requirements intended to treat
hazardous soil conditions involve removal, proper fill selection, and compaction. Expansion or large‐scale settlement

problems would not be a substantial constraint to development of individual sites provided that adequate soil and
foundation studies are performed prior to construction in accordance with existing General Plan policies and CBC
regulations. The City requires the completion of detailed soils reports and ensures that the project design follows the
recommendation in the report. In addition, the Municipal Code identifies building requirements to ensure the safety of life
and property through the regulation of development under Title 15 Building and Construction, Section 15.04 –
Construction and Fire Prevention Regulations. Adherence to the City’s General Plan and the City’s Municipal Code, and
implementing proper engineering, including compliance with the CBC, will ensure that potential expansive soils and
differential settlement impacts remain less than significant. Individual development will be required to undergo separate
environmental review, which may result in specific impacts that require project specific mitigation consistent with these
policies. Adherence to the existing City’s General Plan, the City Municipal Code, and implementing proper engineering,
including compliance with the CBC, will ensure that potential impacts related to expansive soils remain less than
significant.
The proposed Project, by itself, does not propose or authorize any development. Future land uses that occur pursuant to the
proposed Zoning Regulations Update would be required to conform to all General Plan policies, and applicable regulations,
standards and design standards of the Municipal Code and CBC that address geologic hazards, including expansive soils.
Therefore, potential impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Zoning Regulations Update would not make changes to the Municipal Code that addresses expansive soils.
Additionally, the proposed Project would not allow new development in areas where such development is prohibited under
the LUCE. Therefore, there would be no new impacts related to expansive soils that have not been previously examined or
adequately addressed in LUCE EIR, Section 4.6 Geology and Soils.
e) The entirety of the City is served by established wastewater conveyance and treatment services, and new development
would connect to the municipal system. Therefore, the proposed Zoning Regulations Update would not result in impacts
associated with soils supporting the use of septic systems. No impacts would occur.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Zoning Regulations Update would not result in the construction of new septic systems within the City, as new
development would connect to the existing municipal system. Therefore, no impact would occur.

As outlined in LUCE EIR Section 4.7 Global Climate Change, prominent GHG emissions contributing to the greenhouse effect
are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and
sulfur hexafluoride (SF6). Anthropogenic (human‐caused) GHG emissions in excess of natural ambient concentrations are
responsible for intensifying the greenhouse effect and have led to a trend of unnatural warming of the earth’s climate, known as

global climate change or global warming. Global sources of GHG emissions include fossil fuel combustion in both stationary
and mobile sources, fugitive emissions from landfills, wastewater treatment, agricultural sources, deforestation, high global
warming potential (GWP) gases from industrial and chemical sources, and other activities. The major sources GHG emissions
in the City are transportation‐related emissions from cars and trucks, followed by energy consumption in buildings. These local
sources constitute the majority of GHG emissions from community‐wide activities in the city, and combine with regional,
statewide, national, and global GHG emissions that result in the cumulative effect of global warming, which is causing global
climate change. A minimum level of climate change is expected to occur despite local, statewide, or other global efforts to
mitigate GHG emissions. The increase in average global temperatures will result in a number of locally‐important adverse
effects, including sea‐level rise, changes to precipitation patterns, and increased frequency of extreme weather events such as
heat waves, drought, and severe storms.
Statewide legislation, rules and regulations that apply to GHG emissions include the Global Warming Solutions Act of 2006
(Assembly Bill [AB] 32), Climate Pollution Reduction Beyond 2020 Healthier Communities and a Stronger Economy (Senate
Bill [SB] 32), the Sustainable Communities and Climate Protection Act of 2008 (Senate Bill [SB] 375), Advanced Clean Cars
Rule, Low Carbon Fuel Standard, Renewable Portfolio Standard, California’s Green Building Standards Code (CALGreen),
and recent amendments to the California Environmental Quality Act (CEQA) pursuant to SB 97 with respect to analysis of
GHG emissions and climate change impacts. Plans, policies and guidelines have also been adopted at the regional and local
level that address GHG emissions and climate change effects in the City. The San Luis Obispo County Air Pollution Control
District (APCD) adopted a CEQA Air Quality Handbook, as well as guidance on GHG emission thresholds and supporting
evidence, that may be applied by lead agencies within San Luis Obispo County (APCD April 2012, APCD March 2012). The
City also adopted a Climate Action Plan (CAP) that includes a GHG emissions inventory, identifies GHG emission reduction
targets, and includes specific measures and implementing actions to both reduce community‐wide GHG emissions and help the
city build resiliency and adapt to the effects of climate change.
a, b) LUCE EIR Section 4.7 Global Climate Change addresses the potential impacts resulting from implementation of the
LUCE, including short-term and long-term GHG emissions. As discussed in the LUCE EIR, the City conducted a GHG
emissions inventory of annual emissions for the baseline year 2005. This 2009 inventory includes estimated
community‐wide emissions for the transportation, residential and commercial/industrial energy usage (electricity and
natural gas), and solid waste sectors. The City’s CAP also includes forecasted business‐as‐usual (BAU) emissions for 2010,
2020 and 2035, consistent with population, housing and employment data for 2010 and projections for 2020 and 2035.
Forecasted 2020 and 2035 emissions were estimated based on growth rates provided by the San Luis Obispo Council of
Governments (SLOCOG). The CAP BAU forecast supersedes forecasted emissions included in the original inventory,
conducted in 2009. The baseline inventory and BAU forecasts are summarized in LUCE EIR Section 4.7 Global Climate
Change, Table 4.7‐1 Baseline and Forecasted GHG Emissions. As shown in this table, communitywide BAU emissions
were estimated to increase by approximately 9 percent in 2020 compared to 2005 levels and would further increase by
approximately 21 percent in 2035 compared to 2005 levels.
LUCE EIR Conclusion
Projected growth in housing and employment assumed under the LUCE was determined to be equal to or slightly less than
the growth projections used to estimate worst case, “business‐as‐usual” (BAU) future GHG emissions in the CAP.
Therefore, expected long‐term operational GHG emissions generated by new development consistent with the LUCE
would be consistent with forecasted BAU communitywide emissions in the CAP. The CAP includes a communitywide
GHG emissions reduction target of 15 percent below 2005 levels by 2020. This target can also be expressed as a 22 percent
reduction below the projected BAU forecast by 2020, which takes into account anticipated growth in population, housing
and employment and associated changes in the built environment. The CAP includes specific GHG reduction measures in
the CAP that are designed to achieve this target, in combination with state and federal legislative reductions. As shown in
LUCE EIR Section 4.7 Global Climate Change, Table 4.7‐2 CAP Community-wide GHG Emissions Reductions in 2020
and 2035, which includes expected emissions reductions from CAP GHG reduction measures along with State legislative
reductions and the resulting net emissions expected in 2020 and 2035 as a result of implementation of all CAP measures,
community-wide emissions would be reduced to 16 percent below 2005 levels by the year 2020, exceeding the 15 percent

target. LUCE EIR Section 4.7 Global Climate Change, Table 4.7‐3 Consistency of Proposed LUCE Update Policies and
Program with Climate Action Plan Measures and Actions summarizes the LUCE policies that would support or directly
result in the reduction of GHG emissions or serve as climate adaptation strategies, and provides a reference to
corresponding CAP strategies and implementing actions, where applicable, to demonstrate consistency with the adopted
CAP. The LUCE EIR concluded that because the LUCE update included policies and programs that are consistent with
GHG reduction policies and measures that are in the CAP, communitywide GHG emissions reductions assumed in the CAP
were applicable to the proposed LUCE update. Therefore, the LUCE EIR determined that the incremental contribution of
GHG emissions associated with implementation of the LUCE would not be cumulatively considerable, and implementation
of proposed and existing policies would reduce potential impacts to a less‐than‐significant level.
The LUCE EIR concluded that “implementation of the proposed LUCE Update could result in an increase in GHG
emissions due to short-term construction and long‐term operational activities associated with new housing and commercial
development, resulting in a cumulatively considerable contribution to the impact of global climate change. However,
because the proposed LUCE Update would be consistent with the City’s CAP and incorporates applicable CAP policies
and programs that would reduce GHG emissions, this impact would be considered Class III, less than significant” (LUCE
EIR Section 4.7 Global Climate Change, Impact GCC-1).
Proposed Zoning Regulations Update Analysis and Conclusions
The proposed Zoning Regulations Update is one of the principal tools for implementing the LUCE and will advance
greenhouse gas reduction goals as mandated by the State (AB32, SB375) and the City’s CAP. The proposed Project
facilitates the development of a sustainable, multi-modal community to reduce per capita VMT and GHG emissions
through increased design standards, new design guidelines, and the imposition of general site regulations. The adopted
CAP will be undergoing a substantive revision, and the policy directives in the updated CAP will guide City action on
GHG reduction strategies in all City regulatory documents. However, the current CAP includes several policy directives
that can be implemented now via the Zoning Regulations Update. The Planning Commission has reviewed a white paper
outlining possible implementation strategies, and at the May 3, 2018 community workshop, participants suggested
additional strategies that might be addressed in the Zoning Regulations Update. It should be noted that the City is already
forward thinking in its climate adaption strategies and has adopted measures to reduce the City’s carbon footprint, such as
requiring extensive tree canopy in parking lots (which reduces heat island effects and improves carbon sequestration),
requiring wiring for electric vehicle charging in garages in new subdivisions, and requiring LEED Silver or equivalent
development as an incentive in the C-D zone. Also, the State is moving forward with climate change initiatives, such as
requiring solar installations on new development beginning in 2020, which will be applied to new developments. New
strategies in the updated Zoning Regulations include:
As an incentive for increased height in the C-D zone and a community benefit for a PD overlay, having a developer
provide net-zero energy construction features
Reducing the allowable pervious surface coverage in front yards of R-1 zones from 50 percent to 40 percent
As an incentive for increased height in the C-D zone and a community benefit for a PD overlay, requiring a
Transportation Demand Management (TDM) program that achieves measurable 20 percent mode shift and that is
covenanted for long-term implementation
Allowing shared car services (e.g., ZipCar) spaces to be located in developments without increased parking
requirements
Parking requirements for alternative clean fuel vehicles
Requirements for showers, lockers and changing rooms for large developments
Reducing car parking requirements and increasing bike parking
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Buildout pursuant to
the LUCE and the proposed Project would increase development intensity within the city limits, as well as undeveloped
areas to a more built environment, thereby resulting in the generation of GHGs. As noted above, the General Plan, CAP,
and policies adopted in the LUCE protect air quality and facilitate GHG reductions through policies and plan review. In

addition, proposed regulated performance standards applicable to future development require that “The use of
conventional energy sources for space heating and cooling, water heating, and illumination shall be minimized by means
of proper design and orientation, including provision and protection of solar exposure” (proposed Zoning Regulations
Section 17.74.050, Energy Conservation). Adherence to these requirements would reduce any impacts from buildout
occurring under the proposed Zoning Regulations Update, to less than significant. Therefore, the proposed Project would
be consistent with the CAP and impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project includes updates that would facilitate implementation of the goals identified in the City’s CAP, which
would facilitate GHG reductions consistent with local and state regulations. Additionally, the proposed Project would not
allow new development in areas where such development is prohibited under the LUCE. Therefore, there would be no new
impacts related to GHGs and global climate change that have not been previously examined or adequately addressed in
LUCE EIR Section 4.7 Global Climate Change.

Hazardous Materials. Hazardous materials are defined as substances with physical and chemical properties of ignitability,
corrosivity, reactivity, or toxicity which may pose a threat to human health or the environment. This includes, for example,
chemical materials such as petroleum products, solvents, pesticides, herbicides, paints, metals, asbestos, and other regulated

chemical materials. Additionally, hazards include known historical spills, leaks, illegal dumping, or other methods of release of
hazardous materials to soil, sediment, groundwater, or surface water. If a historical release exists, then there is a risk associated
with disturbing the historical release area. Examples of these are gas stations and areas that historically included oil production.
The potential for risks associated with hazardous materials are varied regionally. The primary risk concerns identified by the
city, as stipulated in the City’s Safety Element, include radiation hazards and the transportation of hazardous materials in and
around the city.
Because of the widespread use of hazardous materials in our communities, minor and major hazardous materials spills and
incidents occur. Most of these incidents are related to the increasing frequency of transport of chemicals over roadways,
railways or through industrial accidents. US 101 and a rail corridor are major transportation corridors through the San Luis
Obispo area. Trains and trucks commonly carry a variety of hazardous materials, including gasoline and various crude oil
derivatives, and other chemicals known to cause human health problems. When properly contained, these materials present no
hazard to the community. But in the event of an accident or derailment, such materials may be released, either in liquid or gas
form. In the case of some chemicals (such as chlorine), highly toxic fumes may be carried far from the accident site.
Transporters of hazardous waste in California are subject to many federal and state regulations. They must register with the
California Department of Health Services (DHS) and ensure that vehicle and waste container operators have been trained in the
proper handling of hazardous waste. Vehicles used for the transportation of hazardous waste must pass an annual inspection by
the California Highway Patrol. Transporters must allow the Highway Patrol and/or the DHS to inspect its vehicles and must
make certain required inspection records available to both agencies. The transport of hazardous materials that are not wastes is
regulated by the U.S. Department of Transportation through national safety standards.
Other risks resulting from hazardous materials include the use of these materials in local industry, businesses and agricultural
production. The owner or operator of any business or entity that handles a hazardous material above threshold quantities is
required, by State and Federal laws, to submit a Business Plan to the local Certified Unified Program Agency (CUPA). San
Luis Obispo County Environmental Health Services Division is the CUPA and the City of San Luis Obispo Fire Department
administers the program within the city.
In order to address the risks to health and property associated with hazardous material releases, the City of San Luis Obispo Fire
Department maintains several active programs designed to address emergency situations, including the release of hazardous
materials. Other potential hazards described in further detail in LUCE EIR Section 4.8 Hazards and Hazardous Materials
include radiation, electromagnetic fields, and hazardous trees.
Airport Hazards. The San Luis Obispo County Airport provides commuter, charter, and private aviation service to the area. The
primary hazard associated with land uses near the airport is the risk of aircraft incidents on approach and take‐off. The San Luis
Obispo County Airport Land Use Commission (ALUC) is an independent body of seven members that was created in response
to the mandates of The State Aeronautics Act, first enacted in 1967. As the means of fulfilling these basic obligations, the
ALUC must prepare and adopt Airport Land Use Plans (ALUPs) for each airport within their jurisdiction. In addition to
formulating ALUPs, the ALUC is required to review certain types of action by local counties and cities, which affect the land
use in the vicinity of airports for consistency with the ALUP. Although the ALUC is not part of any local governmental
structure, the City must refer certain local actions to the ALUC. Those local actions include: general plans and general plan
amendments; specific plans and specific plan amendments; zoning ordinances and zoning ordinance amendments; and, building
regulations and modifications thereof.
The policies in the ALUP are intended to minimize the public’s exposure to excessive noise and safety hazards while providing
for the orderly expansion of airports (Public Utility Code Section 21670(a)(2) (refer to LUCE EIR Section 4.8 Hazards and
Hazardous Materials, Figure 4.8‐3 Airport Hazards). The ALUC has developed an ALUP for the San Luis Obispo County
Regional Airport that was first adopted in 1973, was updated in May 2005, and is currently being updated. The ALUP has
identified safety zones with associated land use density and intensity restrictions. The ALUP defines these as: Runway
Protection Zones, Safety Areas S‐1 a through c, and Safety Area S‐2 (refer to LUCE EIR Section 4.8 Hazards and Hazardous
Materials and the ALUP for additional information regarding safety zones).

Fire Risk. Fires have the potential to cause significant losses to life, property, and the environment. Urban fire hazards result
from the materials that make up the built environment, the size and organization of structures, and spacing of buildings.
Additional factors that can accelerate fire hazards are availability of emergency access, available water volume and pressure for
fire suppression, and response time for fire fighters. Fire hazard severity in rural areas, including areas on the edge between
urban and rural land (commonly called the wildland interface), are highly influenced by the slope of the landscape and site
vegetation and climate. Wildland fire hazards exist in at the city’s edges. Refer to LUCE EIR Section 4.8 Hazards and
Hazardous Materials, Figure 4.8‐1 Fire Hazard Severity Zones, for a detailed depiction of the wildland fire risk assessment for
the city’s outlying areas.
Government Code Sections 51175 through 51189 require identification of land within very high fire hazard severity zones to
identify measures that will mitigate uncontrolled fires that threaten to destroy resources, life, or property, and to require that
those measures be taken (refer to LUCE EIR Section 4.8 Hazards and Hazardous Materials, Figure 4.8‐1 Fire Hazard Severity
Zones). Properties within these zones are required to utilize Wildland‐Urban Interface Fire Area Building Standards to
minimize the threat of property damage in the event a wildfire occurs in close proximity to these properties. The objective of
the Wildland‐Urban Interface Fire Area Building Standards is to establish minimum standards for materials and construction to
provide a reasonable level of exterior wildfire exposure protection for buildings in Very High Fire Hazard Severity Zones and
other areas designated by the City Council after a public hearing. The City has not identified a separate Wildland‐Urban
Interface Fire Zone but rather has determined it to be coterminous with the state‐identified Very High Fire Hazard Severity
Zone. However, local building code has been adopted to address the idea that the City is within an area that may put the
community at risk of impacts from wildland fires and has increased construction requirements to address fire hazard. For
additional information regarding factors that contribute to wildfire risk, refer to LUCE EIR Section 4.8 Hazards and Hazardous
Materials.
a), b), c), d), g) LUCE EIR Conclusion
Exposure to Hazardous Materials. Implementation of the LUCE would facilitate new development (including residences)
within several areas in and around the city where hazardous materials could be stored or used, or where previous use has
resulted in contamination of the site. Residential development proximate to commercial or industrial facilities using or
storing hazardous materials has the potential to increase the risk of exposure to harmful health effects. Areas where users of
hazardous materials are located are confined primarily to commercial and industrial areas of the city. Construction
activities may require the use of hazardous materials, which could be a threat if they were to have an adverse impact on the
public or environment. This includes the generation of hazardous waste, potential release or explosion of substances, and
construction taking place within a quarter mile of an established or planned school or construction within a site which is
included on a list of hazardous material sites compiled pursuant to Government Code §65962.5 resulting in the creation of
a significant hazard to the public or the environment. The LUCE EIR notes that by allowing for residential or mixed-use
development in commercial and industrial areas where there may have been past use or there may be current use of
hazardous materials, the potential for exposure may increase due to: (1) potential soil/groundwater contamination resulting
from past practices; and (2) the proximity of new residential development to ongoing activity involving the use of
hazardous materials. Development or redevelopment in these areas would have the potential for exposure of hazardous
materials to the public. The magnitude of exposure to hazards for individual projects would depend upon the location, type,
and size of development and the specific hazards associated with individual sites.
Older structures throughout the city could potentially have asbestos containing materials (ACM) and/or lead‐based paint
(LBP). If demolition of these structures occurred, ACM or LBP could be released, resulting in adverse health effects. To
prevent health risks to occupants or construction workers, proper ACM and LBP abatement and disposal procedures are
required to be undertaken whenever the demolition is considered for structures that were built prior to 1979.
The presence of soil or groundwater contamination would depend upon the location of the construction site and its
proximity to sources of contamination. Depending on the previous land uses, new development could present potential risk
of exposure to contamination associated with agricultural pesticide use, leaking underground storage tanks (LUSTs),
undocumented abandoned oil and gas wells, and/or various industrial contaminants. Hence, development of vacant and
underutilized sites under buildout would increase the potential for exposure to soil and groundwater contamination hazards.

However, any necessary assessment and remediation of the properties would be completed in accordance with applicable
regulatory requirements prior to development. In addition to compliance with General Plan policies and regulatory
requirements, mitigation would be required to reduce potential impacts to a less than significant level. The City of San Luis
Obispo Fire Department will continue to maintain programs designed to address emergency situations, including the
release of hazardous materials.
The LUE includes policies and programs for development near known hazardous material users, or construction in areas
with existing hazardous materials, that could expose individuals to health risks due to soil/groundwater contamination or
emission of hazardous materials into the air. These policies include: 2.3.11 Residential Project Objectives (provide buffers
from hazardous materials transport routes, as recommended by the City Fire Department); 6.4.6 Homesites Outside the
Limit Lines (have effective emergency-vehicle access from a City street or County road); and 12.9 Environmental Review.
The Safety Element lists policies for development near known hazardous material users, or construction in areas with
existing hazardous materials or general hazardous conditions, that could expose individuals to health risks due to
soil/groundwater contamination or emission of hazardous materials into the air which include: Safety Element Policies 6.1
(Other Hazardous Materials), 6.2 (Minimizing Hazardous Materials Exposure), 6.3 (Hazardous Materials in City
Operations). In addition, the Safety Element includes a comprehensive set of policies and programs intended to address
avoiding and preparing for emergencies in general. This includes programs and requirements intended to avoid several
kinds of emergencies and to respond to those that occur (refer to Safety Element Policies 10.0 through 10.23).
The City Demolition and Moving of Buildings Section 115 Public Safety Requirements include general requirements for
building demolition activities, permitting for such activities, hauling operations, and routes of moving materials in order to
address hazardous materials issues. In addition, there are subsections included for dust and debris, fire safety, and removal
and disposal of demolition materials. In addition, adherence to the Federal Asbestos NESHAP regulations and State and
Federal regulations pertaining to the abatement of lead-based paints will reduce expose of these materials. In addition, the
City of San Luis Obispo Fire Department Hazardous Waste Generator Permit ensures that the City Fire Department permits
hazardous waste generators in San Luis Obispo County.
The LUCE EIR states that based on compliance with the General Plan and existing regulations summarized above, future
development implemented pursuant to the LUCE would not impair implementation of or physically interfere with an
adopted emergency response plan or emergency evacuation plan (LUCE EIR Section 4.8, Hazards and Hazardous
Materials).
The LUCE EIR determined that “development facilitated by the LUCE Update could occur near known hazardous material
users or result in construction in areas with existing hazardous materials. Implementation of the LUCE Update could
expose individuals to health risks due to soil/groundwater contamination or emission of hazardous materials into the air and
could impact an adopted emergency response/evacuation plan. With the incorporation of the proposed LUCE Update
policies and existing City policies, potential impacts are considered Class III, less than significant” (LUCE EIR Section
4.8, Impact HAZ‐1).
Proposed Zoning Regulations Update Analysis and Conclusions
Similar to the analysis identified in the LUCE EIR and summarized above, implementation of the proposed Zoning
Regulations Update has the potential to result in significant impacts related to the introduction of new development near
known hazardous material users, or construction in areas with existing hazardous materials, that could expose individuals
to health risks due to soil/groundwater/materials contamination or emission of hazardous materials into the air. Upon
review of specific projects and development proposals, where required, further review including completion of phased
Environmental Site Assessments to determine the potential for hazardous materials, soil and groundwater sampling, and
documented recommendations for remediation under the appropriate oversight agency would reduce the risk of possible
contamination. In addition, compliance with General Plan policies and current federal and state requirements would reduce
impacts to less than significant levels.

LUCE EIR Conclusion
Regarding potential exposure to hazardous materials transported by rail and highway, development along the railroad
tracks would be most susceptible to hazardous materials impacts associated with railway accidents, and development along
Highway 101 would be most susceptible to hazardous materials impacts associated with highway accidents. Applicable
policies and programs that address this impact include: Safety Element Policies 9.1 Hazardous Materials; Policy 6.2
Minimizing Hazardous Materials Exposure; Policy 6.3 Hazardous Materials in City Operations.
The LUCE EIR determined that “development under the proposed LUCE Update could potentially introduce sensitive
receptors to areas in direct proximity to hazardous materials transportation corridors including the Union Pacific Railroad
and Highway 101 and could potentially create a public safety hazard. This is a Class III, less than significant impact”
(LUCE EIR, Section 4.8 Hazards and Hazardous Materials, Impact HAZ-5).
Proposed Zoning Regulations Update Analysis and Conclusions
Consistent with the conclusions of the LUCE EIR, impacts to new development implemented pursuant to the Zoning
Regulations Update are considered potentially significant; however, based on compliance with existing General Plan
policies and programs, impacts related to hazards from rail and highway accidents and the transportation of hazardous
materials within the city would be reduced to a less than significant level.
LUCE EIR Conclusion
Other Hazards. The LUCE EIR also identified other potential hazards including radiation, electromagnetic fields, and
hazardous trees. The Diablo Canyon Nuclear Power Plant, which is pending closure estimated in 2024-2025, is the primary
hazard for ionizing radiation in the San Luis Obispo area. Emergency planning at the Diablo Canyon facility is coordinated
with the Emergency Services Director from the Office of the County Administer and the state Department of Health
Services (DHS) provides oversight and guidance on many health-related issues. Applicable response plans for an
emergency at the Diablo Canyon Nuclear Power Plant include the State of California Emergency Plan the San Luis Obispo
County/Cities Nuclear Power Plant Emergency Response Plan. Implementation of the LUCE would have the potential to
introduce residents to regional hazards associated with a radiation leak at Diablo Canyon Nuclear Power Plant.
Incorporation of the existing state and federal regulations and compliance with local response plan implemented by the
County and City of San Luis Obispo will reduce impacts related to radiation hazards to less than significant levels.
Regarding electromagnetic fields, which have the potential to affect biological systems, the LUCE EIR determined that
implementation of Safety Element Policies 7.0 Exposure to Electromagnetic Fields and 7.1 Notification to Buyers Near
Electromagnetic Fields would reduce impacts related to exposure to electromagnetic fields are reduced to less than
significant levels.
The City Municipal Code, Ordinance 1544 Tree Ordinance, outlines the regulatory procedures and authority for the
trimming or removal of hazardous trees. Safety Element policies and programs to minimize danger to people and property
from trees that are weakened and susceptible to falling or limb loss during storms include: Policy 9.0 Hazardous Trees and
Program 9.1 Hazardous Trees. The LUCE EIR determined that implementation of the City’s policies and programs and
Tree Ordinance will reduce safety impacts to less than significant levels. In addition to the policies and programs listed
above, the Safety Element includes a comprehensive set of policies and programs intended to address avoiding and
preparing for emergencies in general. Safety Element Policies and Programs 10.0 through 10.9 are intended to avoid
several kinds of emergencies and to respond to those that occur.
The LUCE EIR concluded that “development facilitated by the LUCE Update could introduce sensitive receptors to
additional hazards related to exposure to radiation, electromagnetic fields and hazardous trees. With the incorporation of
the proposed LUCE Update policies and existing City policies, potential impacts are considered Class III, less than
significant” (LUCE EIR, Section 4.8 Hazards and Hazardous Materials, Impact HAZ-4).

Proposed Zoning Regulations Update Analysis and Conclusions
Implementation of the Zoning Regulations Update would result in the same impacts identified for the LUCE Update, as
summarized above. Consistent with the analysis and determinations in the LUCE EIR, development facilitated by the
proposed Zoning Regulations Update could occur near known hazardous material users and hazardous materials
transportation corridors, result in construction in areas with existing hazardous materials, could expose individuals to health
risks due to soil/groundwater contamination or emission of hazardous materials into the air, could impact an adopted
emergency response/evacuation plan. Additionally, future development could introduce sensitive receptors to hazards
associated with radiation, electromagnetic fields and hazardous trees. Adherence to the General Plan, Municipal Code,
CBC, existing and proposed Zoning Regulations, and federal and state regulations, and avoidance and remediation of
hazardous sites and conditions, will ensure that potential impacts related to hazards and hazardous materials will remain a
less than significant impact. Individual development would be required to undergo separate environmental review, which
may result in specific impacts that require project specific mitigation consistent with existing regulations, policies, and
programs.
In addition to existing plans, policies, and programs summarized above, the Zoning Regulations Update includes several
proposed modifications to further reduce potential impacts, consistent with the LUCE. Proposed Article 3 of the Zoning
Regulations Update includes clarifications regarding hazards and hazardous materials, which would provide further
protections for the public, including:
Limitations on use for mixed-use projects, which clarify that major vehicle/equipment repair, uses that required storage
of hazardous materials beyond what is normally associated with residential uses, manufacturing or industrial activities,
and any other activity or use incompatible with residential activities and/or having the possibility of affecting the
health or safety of mixed-use development residents);
Clarified performance standards stating that “land or buildings shall not be used or occupied in a manner creating any
dangerous, injurious, or noxious fire, explosive, or other hazard that would adversely affect the surrounding area”;
A new section stating that “The use, handling, storage and transportation of hazardous and extremely hazardous

New trash enclosure standards to avoid health and safety hazards.
In addition, revisions to Article 4 propose restrictions for locating schools within 1,000 feet of any business posing
significant health risk to the school due to the presence of hazardous materials or conditions, and Article 6 states that
required findings for a Minor Use Permit or Conditional Use Permit include the following: “The type, density, and intensity
of use being proposed will not endanger, jeopardize, or otherwise constitute a hazard to the public convenience, health,
interest, safety, or general welfare, or be materially detrimental or injurious to the improvements, persons, property, or uses
in the vicinity and zone in which the property is located.”
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. The proposed changes
do not conflict with existing General Plan policies nor state and federal regulations applicable to public safety and exposure
to hazards and hazardous materials. Future land uses that occur pursuant to the proposed Zoning Regulations Update would
be required to conform to all General Plan policies, and applicable regulations, standards and design standards of the CBC,
Municipal Code, and state and federal regulations address hazardous and hazardous materials. Based on compliance with
existing policies and regulations, and proposed regulations identified in the Zoning Regulations Update, potential impacts
related to hazards and hazardous materials would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE and to
further reduce potential impacts related to hazards and hazardous materials. The proposed Project would not allow new

development in areas where such development is prohibited under the LUCE. Therefore, there would be no new impacts
related to hazards and hazardous materials that have not been previously examined or adequately addressed in LUCE EIR,
Section 4.8 Hazards and Hazardous Materials.
e), f) The policy and programs presented in LUE Chapter 7 Airport Area reflect airport safety, noise, height and overflight
considerations consistent with the purposes of the State Aeronautics Act. Policies, programs, and Zoning Regulations
implementation were previously incorporated into the Airport Overlay Zone (AOZ) to codify airport compatibility criteria
for areas subject to airport influence consistent with the requirements of Cal. Pub. Utilities Code Section 21670, et. seq, the
California Airport Land Use Planning Handbook, and other related federal and state requirements relating to airport land
use compatibility planning. These include allowable uses and development standards such as density and intensity
limitations, identification of prohibited uses, infill development, height limitations, and other hazards to flight, noise
insulation, buyer awareness measures, airspace protection, nonconforming uses and reconstruction, and the process for
airport compatibility criteria reviews by the City.
LUCE EIR Conclusion
The LUCE EIR states that “adherence to the existing City’s General Plan, and coordination with the ALUC, will ensure
that future development under the LUCE will not result in significant airport‐related safety hazards. Individual
development would be required to undergo separate environmental review, which may result in specific impacts that
require project specific mitigation consistent with these policies”.
The LUCE EIR concluded that “development consistent with the proposed LUCE Update could introduce incompatible
residential and commercial land uses into safety zones established through the Airport Land Use Plan and may result in a
safety hazard for people residing or working in these areas. Impacts would be Class III, less than significant” (LUCE EIR
Section 4.8 Hazards and Hazardous Materials, Impact HAZ-2).
Proposed Zoning Regulations Update Analysis and Conclusions
Consistent with the LUCE EIR, implementation of the Zoning Regulations Update would facilitate development within the
boundary of the ALUP and City AOZ. In association with adoption of the LUCE and associated Airport Land Use
Compatibility Report, the City Council approved an overrule of the ALUP, which allowed for development to occur
pursuant to adopted Specific Plans or existing Zoning Regulations Chapter 17.57 Airport Overlay Zone and associated
Table 10 – Airport Overlay Zone (AOZ) – Maximum Allowed Persons. The Draft Zoning Regulations Update restructured
this section of the Zoning Regulations as Chapter 17.64 and includes clarifications to how density is to be calculated
(consistent with the California Airport Land Use Planning Handbook) and includes updates specific to the names of land
uses, consistent with the remainder of the proposed Update (refer to Article 2 of the proposed Project). The proposed
Zoning Regulations Update would not modify the allowable density (persons per acre) for each use within identified Safety
Zones.
Development consistent with the LUCE and Zoning Regulations Update could introduce incompatible residential and
commercial land uses into safety zones identified in the ALUP and may result in a safety hazard for people residing or
working in these areas. However, the proposed and existing City policies and programs and compliance with the Municipal
Code directly address future development with the potential to airport‐related safety hazards. As future development
pursuant to the Zoning Regulations Update is proposed, the City will be required to ensure consistency with the General
Plan and Municipal Code. Implementation of proposed and existing policies and reliance on establishment of
project‐specific mitigation measures where appropriate would reduce potential impacts to a less than significant level.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. The proposed changes
do not conflict with existing General Plan policies nor state and federal regulations applicable to public safety and airport
hazards. Future land uses that occur pursuant to the proposed Zoning Regulations Update would be required to conform to
all General Plan policies, and applicable regulations, standards and design standards of the General Plan, Municipal Code,

and state and federal regulations that address airport safety. Based on compliance with existing policies regulations,
potential impacts related to airport hazards would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not allow new development in areas where such development is prohibited under the LUCE and
Table 10 – Airport Overlay Zone (AOZ) – Maximum Allowed Persons. Therefore, there would be no new impacts related to
airport safety that have not been previously examined or adequately addressed in LUCE EIR, Section 4.8 Hazards and
Hazardous Materials.
h) LUCE EIR Conclusion
Buildout of the LUCE would facilitate the development of residential uses in areas of the City that are at risk of damage
from wildland fires. As shown on LUCE EIR Section 4.8 Hazards and Hazardous Materials, Figure 4.8‐1 City of SLO
Planning Area Fire Hazard Severity Zones, the northern portion of the city, consisting of the land surrounding Via Carta
and Poly Canyon Road and along the north‐eastern edge behind Cal Poly State University is a High to Very High Fire
Hazard area. The southeast quadrant of the intersection of Highway 1 and Highway 101 directly east of the French Hospital
Medical Center is also designated as a High Fire Hazard area. In addition, Moderate Fire Hazard Areas are located along
the southern portion of the city between Highway 101 and Highway 227. Development of vacant and/or underutilized
parcels in these areas has the potential to result in an increased risk of exposure to wildland fires. The Uniform Fire Code
(UFC) and CBC set construction requirements for residences and structures in wildland fire hazard areas. Compliance with
these requirements would minimize risks associated with development in these areas. Compliance with General Plan
policies would further reduce the risks in these areas. The remainder of the urbanized city has a low/moderate potential for
wildland fires. However, seep hills covered with brush and grasslands surround San Luis Obispo, and during fire season
areas within the city limits are susceptible to wildfire damage if these fires cannot be prevented or controlled. The City has
adopted fire safety standards relating to road standards for fire equipment access, standards for signs identifying streets,
roads, and buildings, minimum private water supply reserves for emergency fire use, and fuel breaks and greenbelts as
outlined in the California Public Resources Code Section 4290 and Section 4291. These standards apply to all development
outside of the incorporated city and would help to reduce the risk of wildfires spreading and impacting the city.
The Safety Element lists policies to protect areas designated as Moderate or High Wildland Fire Hazard which include
Policies 3.0 Adequate Fire Services and 3.1: Wildland Fire Safety. In addition, the Safety Element includes a
comprehensive set of policies and programs intended to address wildland fire hazards. This includes the following
programs and requirements intended to avoid several kinds of emergencies and to respond to those that occur: Policy 10.1
Emergency Preparedness and Response; Program 10.3 Response Performance Standards; Program 10.5 Specific
Emergency‐Response Information; Program 10.6 Coordinated Emergency Planning; Program 10.7 Emergency Operations
Center; Program 10.9 City Emergency Plan; Program 10.10 Mutual and Automatic Aid; Policy 10.13 Emergency Access
and Evacuation; Policy 10.18 Safety of Structures and Facilities; Program 10.19 Reducing Structural Hazards; Program
10.22 Building and Fire Regulations; and Program 10.23 Required Inspections.
The LUCE EIR determined that “development consistent with the proposed LUCE Update would introduce residential land
uses into areas designated as having a Moderate or High Wildland Fire Hazard, introducing the potential to expose people
or structures to a significant risk of loss and/or injury. However, compliance with existing policies and state and local
regulations would reduce impacts to a Class III, less than significant level” (LUCE EIR Section 4.8 Hazards and Hazardous
Materials, Impact HAZ‐3).
Proposed Zoning Regulations Update Analysis and Conclusions
Consistent with the analysis in the LUCE EIR, development pursuant to the Zoning Regulations Update would introduce
residential land uses into areas designated as Moderate or High Wildland Fire Hazard, introducing the potential to expose
people or structures to a significant risk of loss and/or injury. However, the existing City policies and programs and

proposed regulations discussed above directly address future development in areas designated as Moderate or High
Wildland Fire Hazard. As future development under the Zoning Regulations Update is proposed, the City will be required
to ensure consistency with the General Plan. In addition to existing regulations that refer to fire safety and compliance with
the UFC, the proposed Zoning Regulations Update includes additional protective regulations related to fire risk, including
clarified Hillside Development Standards in Article 3, which are provided to “protect the health, safety and welfare of
community residents by directing development away from areas with hazards such as landslides, wildland fires, flooding
and erosion.” Therefore, implementation of proposed and existing policies and reliance on establishment of project‐specific
mitigation measures where appropriate would reduce potential impacts to a less than significant level.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. The proposed changes
do not conflict with existing General Plan policies nor state and federal regulations applicable to fire risk. Future land uses
that occur pursuant to the proposed Zoning Regulations Update would be required to conform to all General Plan policies,
and applicable regulations, standards and design standards of the General Plan, Municipal Code, UFC, and CBC
regulations that address fire safety. Based on compliance with existing policies regulations, potential impacts related to fire
hazards would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not allow new development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new impacts related to fire hazards that have not been previously examined or adequately
addressed in LUCE EIR, Section 4.8 Hazards and Hazardous Materials.

Drainage and Flooding. The City is located within the San Luis Obispo Creek Hydrologic Subarea of the Estero Bay
Hydrologic Unit, which stretches roughly 80 miles between the Santa Maria River and the Monterey County line and includes
numerous individual stream systems. According to the Safety Element of the City of San Luis Obispo General Plan, average
seasonal precipitation in the City of San Luis Obispo is 22 inches and average seasonal precipitation throughout the county
varies from 8.5 inches (at Simmler) to 25.6 inches (at San Simeon). The watershed generally drains to the south‐southwest via
San Luis Obispo Creek where it meets the Pacific Ocean at Avila Beach. San Luis Obispo Creek originates in the Cuesta Grade
area north of San Luis Obispo at an elevation of 2,200 feet above mean sea level, in the western slopes of the Santa Lucia
Range. The creek flows south through the City of San Luis Obispo adjacent to U.S. Highway 101 until it reaches the southern
extent of the Irish Hills where it veers west to the ocean.
The City is generally located within a low‐lying valley centered on San Luis Obispo Creek. San Luis Obispo Creek is one of
four major drainage features that create flood hazards in the city, with the others being Stenner Creek, Prefumo Creek, and Old
Garden Creek. In addition, many minor waterways drain into these creeks, and these can also present flood hazards. Because of
the high surrounding hills and mountains in the area, the drainage sheds of these creeks are relatively small, but the steep slopes
and high gradient can lead to intense, fast moving flood events in the city. Key areas within the 100‐Year Flood Zone include:
Downtown (especially bounded by Santa Rosa, Monterey, Broad, and Pismo Streets); Mid‐Higuera Area; and Margins of
Laguna Lake and Prefumo Creek (refer to LUCE EIR Section 4.9 Hydrology and Water Quality, Figure 4.9‐1 100-year Flood
Zones). San Luis Obispo is not subject to inundation from dam failure, beach erosion, or coastal or lakefront flooding due to
earthquake‐induced waves (tsunami or seiche).
Water Quality. The City’s Public Works, Utilities, and Community Development Departments are responsible for coordinating
the implementation of the City’s Storm Water Management Program (SWMP). This program is required under the Phase II
Storm Water Regulations regulated by the SWRCB, San Luis Obispo Region. The primary goal of the program is to minimize
urban runoff that enters the municipal storm drain system, and carries bacteria and other pollutants into local creeks, our
watershed and to the ocean. As part of these new requirements, the City of San Luis Obispo has been mandated to establish a
set of minimum-designated Best Management Practices (BMPs) and Pollution Prevention Methods (PPMs). BMPs are steps
taken to minimize or control the amount of pollutants and runoff. PPMs are strategies to eliminate the use of polluting materials,
and/or not exposing potential pollutants to rainwater or other runoff.
San Luis Obispo Creek has been designated by the Central Coast Regional Water Quality Control Board (RWQCB) as having
present and potential beneficial uses for municipal supply; agricultural supply; groundwater recharge; recreation; wildlife
habitat; warm and cold fresh water habitat; migration of aquatic organisms; spawning, reproduction, and/or early development
of fish; and commercial and sport fishing. As documented in LUCE EIR Section 4.9 Hydrology and Water Quality, water
quality in the San Luis Obispo Creek drainage system is generally considered to be good; however, the water quality fluctuates
along with seasonal changes in flow rates. In summer months, when the flows decrease and dilution is reduced, water quality
decreases. According to the RWQCB Total Maximum Daily Load (TMDL) Project for San Luis Obispo Creek, the creek has
been reported to exceed nutrient and pathogen levels. Nitrate sources contributing to the nutrients identified in TMDL Project
are, in decreasing order of contribution: City of San Luis Obispo Water Resource Recovery Facility (WRRF), croplands,
background, reservoirs, and residential areas. The fecal coliform sources identified by the RWQCB TMDL Project are, in
decreasing order of contribution: urban, human, birds and bats roosting in the tunnel, livestock, and background.

Groundwater Quality. Groundwater within the San Luis Obispo Valley Sub‐basin flows toward the south‐southwest, following
the general gradient of surface topography. Groundwater occurs within the alluvial sediments and the underlying weathered and
fractured bedrock. Depth to groundwater in the San Luis Obispo Valley Sub‐basin is estimated to be 15 to 25 feet below ground
surface. Groundwater within the San Luis Obispo area is considered suitable for agricultural water supply, municipal and
domestic supply, and industrial use. For additional information, refer to LUCE EIR Section 4.9 Hydrology and Water Quality.
a), f) LUCE EIR Conclusion
The LUCE EIR notes that potential development in accordance with the LUCE could increase the amount of point and
non‐point sources of contamination, which could affect water quality and groundwater in the City. An increase in point
source and non‐point source pollution could result from increases in development intensity and construction activities
which may directly impact water quality specific to site drainage patterns. Discharge of pollutants from any point source is
prohibited unless the discharge is in compliance with a National Pollutant Discharge Elimination System (NPDES) Permit
issued by the Regional Water Quality Control Board. Generally, pollutants of greatest concern in regulation of point
sources include nutrients (ammonia and nitrate), heavy metals, toxic chemicals, chlorine, and salts.
The LUE includes policies and programs for point and non‐point sources of contamination that has the potential to affect
water quality, including 3.7.3 Air & Water Quality. Industries locating or expanding in San Luis Obispo are required to
comply with all applicable air‐quality and water‐quality regulations. The COSE lists policies for point and non‐point
sources of contamination (10.3.2 Maintain water quality). In addition to the City’s General Plan, the RWQCB has
developed a Basin Plan (2011) designed to preserve and enhance water quality and protect the beneficial uses of all
regional waters. Water quality objectives for the Central Coastal Basin satisfy state and federal requirements established to
protect waters for beneficial uses and are consistent with existing statewide plans and policies. This would ensure that
impacts from point and non‐point sources of contamination will not affect water quality in San Luis Obispo Creek and
groundwater in the City of San Luis Obispo and remain less than significant.
The LUCE EIR concluded that “point and non‐point sources of contamination could affect water quality in San Luis
Obispo Creek, Prefumo Creek as well as other surface waters and groundwater in the city. However, compliance with
existing regulations and implementation of General Plan policies and the City’s Stormwater Management Plan (SWMP)
would result in Class III, less than significant impacts” (LUCE EIR Section 4.9 Hydrology and Water Quality, Impact
HWQ-3).
Proposed Zoning Regulations Update Analysis and Conclusions
Consistent with the analysis and conclusions of the LUCE EIR, construction activities associated with development under
the proposed Zoning Regulations Update could result in the pollution of natural watercourses or underground aquifers. The
types of pollutant discharges that could occur as a result of construction include accidental spillage of fuel and lubricants,
discharge of excess concrete, and an increase in sediment runoff. Regulations under the federal Clean Water Act and the
State require construction activity that disturbs greater than one acre, or that disturbs less than one acre but is part of a
larger common plan of development, to comply with the NPDES State General Construction Permit. The Permit requires
the preparation of a Storm Water Pollution Prevention Plan (SWPPP) that contains specific actions, termed Best
Management Practices (BMPs), to control the discharge of pollutants, including sediment, into local surface water
drainages. A Notice of Intent (NOI) to perform work under the Permit must be filed with the State. In the State of
California, Regional Water Quality Control Boards administer the NPDES permit process for construction sites, with
implementation coordinated with the local agencies under their Phase I and Phase II NPDES Municipal Permits (SWMP).
Increases in development intensity that could occur under the Zoning Regulations Update may incrementally increase
pollutants in surface runoff. New development would be required to comply with current federal, state, and local
requirements, which are more stringent than what was required at the time most existing development within the city was
built. As such, redevelopment of these areas with new projects that incorporate current BMP requirements has the potential
to improve water quality in area drainages. Overall, impacts are anticipated to be less than significant.

Point and non‐point sources of contamination could affect water quality in San Luis Obispo Creek, Prefumo Creek, and
other surface waters and groundwater in the city. In addition to the General Plan and Basin Plan policies, the City’s
Stormwater Quality Ordinance helps maintain the health, safety, and general welfare of citizens, and protects and enhances
the quality of watercourses and water bodies in a manner pursuant to and consistent with the Clean Water Act by reducing
pollutants in storm water discharges to the maximum extent practicable by prohibiting non‐storm water discharges to the
storm drain system and improving storm water management. Compliance with the General Plan and stormwater regulations
summarized above directly address future development with the potential impact from point and non‐point source
contamination. As future development under the Zoning Regulations Update is proposed, the City will be required to
ensure consistency with the General Plan and the policies/programs listed above. Implementation of proposed and existing
policies and reliance on establishment of project‐specific mitigation measures where appropriate would reduce potential
impacts to a less than significant level.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable regulations summarized above that
address stormwater and water quality. Impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. the
proposed Project would not allow new development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new impacts related to stormwater discharge and water quality that have not been previously
examined or adequately addressed in LUCE EIR Section 4.9 Hydrology and Water Quality.
b), c) LUCE EIR Conclusion
The LUCE EIR states that development pursuant to the LUCE could cause an increase in the amount of impervious
surfaces within the city which could lead to the lack of percolation of water to the groundwater basin and could alter
drainage patterns resulting in erosion and/or sedimentation. Potential development may also increase the volume of surface
runoff due to lack of percolation. Future development and redevelopment projects within the City are required to comply
with the Central Coast Regional Water Quality Control Board Post Construction Requirements. Future development could
result in additional runoff from the impervious area constructed. This additional impervious area has the potential result in
an increase in the amount of runoff within the watershed, as well as a marginal decrease in percolation to the groundwater
basin. However, upon compliance with the terms of the City’s SWMP, the LUCE EIR determined that impacts would be
less than significant.
The LUE includes goals, policies and programs to address impacts related to groundwater percolation and recharge and the
altering of existing drainage patterns to less than significant levels, including: 6.6.5 Runoff Reduction and Groundwater
Recharge; 6.6.6 Development Requirements; and 6.7.1 Previously Developed Areas. The Safety Element lists the
following policies that address potential impacts related to groundwater percolation and recharge and the altering of
existing drainage patterns: 2.1 Flood Hazard Avoidance and Reduction and 10.12 Critical Facilities Locations. The COSE
lists goals, policies and programs related to groundwater percolation and recharge and the altering of existing drainage
patterns, including 8.3.3 Open space for safety; 10.2.2 Awhahnee Water Principles; 10.1.3 Goal Water Quality; and, 10.2.1
Water Quality.
The LUCE EIR concluded that “development facilitated by the LUCE Update has the potential to increase the amount of
impervious surfaces within the city. This could result in a decrease in percolation to the Groundwater Basin, the alteration
of drainage patterns and increases in the volume of surface runoff. Compliance with the City’s Stormwater Management
Plan (SWMP) would reduce impacts to a Class III, less than significant level” (LUCE EIR, Section 4.9 Hydrology and
Water Quality, Impact HWQ‐2).

increase the amount of impervious surface within the City. This could result in a decrease in percolation to the
Groundwater Basin, the alteration of drainage patterns and increases in the volume of surface runoff. Adherence to the
existing City’s General Plan, and compliance with the City’s SWMP and Drainage Design Manual (DDM) will ensure that
the creation of additional impervious areas will not increase the amount of runoff within the watershed and will not affect
percolation to the groundwater basin or adversely alter drainage patterns. As such, impacts would be less than significant.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable regulations that address drainage and
storm water runoff, including the City’s SWMP and DDM. Therefore, the proposed Project would not violate any drainage
or stormwater standards. Additionally, the proposed Zoning Regulations Update would not substantially interfere with
groundwater recharge, or substantially alter existing drainage patterns in a manner that would result in substantial erosion
or siltation off-site. Impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. the
proposed Project would not allow new development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new impacts related to groundwater recharge and drainage that have not been previously
examined or adequately addressed in LUCE EIR Section 4.9 Hydrology and Water Quality.
d), g), h) Flooding can cause widespread damage to affected areas and endanger human safety. When urban areas encroach on
floodplains, buildings and vehicles can be damaged or destroyed, while smaller objects can be buried in flood‐deposited
sediments. Floodwaters can break utility lines, interrupting services and potentially affecting health and safety. Floods may
also create health and safety hazards and disrupt vital public services. The secondary effects of flooding are due to standing
water, which can result in crop damage, septic tank failure, and water well contamination. Standing water can also damage
roads, foundations, and electrical circuits. The extent of damage caused by any flood depends on the topography of the area
flooded; depth, duration, and velocity of floodwaters; the extent of development in the floodplain; and the effectiveness of
forecasting, warnings, and emergency operations. Encroachment onto floodplains, such as artificial fills and structures,
reduces the capacity of the floodplain and increases the height of floodwater upstream of the obstructions.
LUE Section 6 Resource Protection includes several policies related to flooding and flood management, including: 6.6
Creeks, Wetlands, and Flooding Policies; 6.6.1 Creek and Wetlands Management Objectives; and 6.6.6 Development
Requirements (project designs shall minimize drainage concentrations and impervious coverage and floodplain areas
should be avoided and, where feasible, any channelization shall be designed to provide the appearance of a natural water
course). LUE 6.7 Creeks and Flooding Programs include: 6.7.1. Previously Developed Areas (to limit the potential for
increased flood damage in urbanized areas, the City shall ensure new development complies with the City’s flood plain
ordinance, setbacks, specific plans, and design standards to minimize flood damage and flood plain encroachment), 6.7.2.
National Flood Program (the City shall administer the National Flood Insurance Program standards); 6.7.3. Creekside Care
and Notification (in maintaining creek channels to accommodate flood waters, the City shall notify owners of creeks and
adjacent properties in advance of work and use care in any needed removal of vegetation), and 6.7.4. Evaluate Use of
Financing Districts. The COSE also includes policies and programs related to floodplain management including 7.7.9
Creek Setbacks, 8.3.3 Open Space for safety, and 10.2.2 Ahwahnee Water Principles. The Safety Element lists goals and
policies aimed to protect from flooding which include 2.1 Flood Hazard Avoidance and Reduction and 10.12 Critical
Facilities Locations.
LUCE EIR Conclusion
The LUCE EIR concluded that “future implementation of the following proposed development area projects and street
network changes would have the potential to result in significant impacts related to flooding or impede or redirect flood
flows. New development under the LUCE Update within the 100‐year flood plain could be subject to flooding and have the
potential to impede or redirect flood flows. However, with implementation of General Plan policies and adherence to the
City’s Floodplain Management Regulation impacts related to flooding would be Class III, less than significant” (LUCE
EIR Section 4.9 Hydrology and Water Quality, Impact HWQ‐1).

Proposed Zoning Regulations Update Analysis and Conclusions
Consistent with the LUCE EIR, development pursuant to the Zoning Regulations Update could result in new development
within the 100‐year floodplain and could introduce structures in areas that could impede or redirect flood flows. Under the
General Plan, any property within the Flood Insurance Rate Program (FIRM) defined 100‐year flood zone is considered as
having a hazard potential requiring specified controls or protective measures. Anticipated development under the proposed
Project could subject new development to flooding impacts. In addition to the General Plan policies listed above, adherence
to the City of San Luis Obispo’s Floodplain Management Zone Regulations, the Waterway Management Program (WMP),
the Drainage Design Manual (DDM), and the Stream Management and Maintenance Program will ensure that impacts from
flooding remain less than significant.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable regulations that address drainage,
storm water runoff, and flooding, including the City’s Floodplain Management Zone Regulations, the WMP, the DDM, and
the Stream Management and Maintenance Program. Therefore, the proposed Project would not violate any drainage or
flooding standards and would not substantially increase the potential for additional flood risk. Additionally, the proposed
Zoning Regulations Update would not substantially alter the existing drainage patterns such that erosion or flooding would
occur. Impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. the
proposed Project would not allow new development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new impacts related to stormwater runoff, drainage, or flooding that have not been previously
examined or adequately addressed in LUCE EIR Section 4.9 Hydrology and Water Quality.
e) LUCE EIR Conclusion
The LUCE EIR states that development facilitated by the LUCE has the potential to incrementally increase the amount of
impervious surface area and place additional demand on existing stormwater conveyance infrastructure, such that new or
expanded infrastructure may be needed. Based on the current regulations of the RWQCB reflected in the City’s Stormwater
Management Plan (SWMP), development and redevelopment projects within the City are required to comply with the
Central Coast Regional Water Quality Control Board Post Construction Requirements. In accordance with these
requirements, future development could result in additional runoff from the impervious area, thereby placing limited
demand on existing or planned stormwater infrastructure. As development occurs, site‐specific stormwater infrastructure
needs would be determined on a project‐specific basis. The LUCE EIR determined that upon compliance with the City’s
SWMP and State regulatory requirements, impacts related to the need for additional stormwater infrastructure would be
less than significant.
The LUCE EIR concluded that “development facilitated by the LUCE Update has the potential to create or contribute
runoff water which would exceed the capacity of existing or planned stormwater drainage systems, resulting in increased
stormwater runoff and has the potential to result in the need for additional stormwater infrastructure. Compliance with the
City’s Stormwater Management Plan (SWMP), and State regulatory requirements, would reduce impacts to a Class III, less
than significant” (LUCE EIR Section 4.9 Hydrology and Water Quality, Impact HWQ-4).
Proposed Zoning Regulations Update Analysis and Conclusions
Consistent with the analysis and conclusions of the LUCE EIR, development facilitated by the Zoning Regulations Update
has the potential to create or contribute runoff water which would exceed the capacity of existing or planned stormwater
drainage systems, resulting in increased stormwater runoff and has the potential to result in the need for additional
stormwater infrastructure. Existing City policies and programs discussed above directly address future development with
the potential impact to exceed the stormwater drainage system. As future development under the Project is proposed, the
City will be required to ensure consistency with the General Plan and the policies/programs listed above. Adherence to the

existing City’s General Plan and compliance with the City’s SWMP and state requirements will ensure that the additional
impervious areas will not result in impacts related to the need for increases in stormwater infrastructure. Individual
development will be required to undergo separate environmental review, which may result in specific impacts that require
project specific mitigation consistent with these policies. Implementation of proposed and existing policies and reliance on
establishment of project‐specific mitigation measures where appropriate would reduce potential impacts to a less than
significant level.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable regulations that address stormwater
runoff. Therefore, the proposed Project would not violate any stormwater standards and impacts would be less than
significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not allow new development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new impacts related to stormwater runoff and impacts to the City’s stormwater conveyance
infrastructure that have not been previously examined or adequately addressed in LUCE EIR Section 4.9 Hydrology and
Water Quality.
i), j) Existing and future development within the City is not subject to inundation from dam failure, beach erosion, or coastal or
lakefront flooding due to earthquake‐induced waves (tsunami or seiche); therefore, no impacts would occur. Refer to Initial
Study Section 6, Geology and Soils, for a discussion of potential impacts due to landslide (mudflow).

Evaluation
The City of San Luis Obispo includes a variety of land use types including residential, mixed-use, commercial, office,
industrial, public/quasi-public, parks and recreation, agriculture, and open space. The City's General Plan guides the use and
protection of various resources to meet community purposes. It reflects consensus and compromise among a wide diversity of
citizens' preferences, within a framework set by State law. The General Plan is published in separately adopted sections, called
elements, which address various topics. The LUE represents a generalized blueprint for the future of the City of San Luis
Obispo. Required by State law, it is the core of the General Plan. Starting with conditions at the time of adoption, the LUE sets
forth a pattern for the orderly development of land within the City's planning area. This pattern should be based on residents'
preference and on protection of natural assets unique to the planning area. The LUE describes the expected level of population
growth resulting from construction of the kinds of housing units included in the plan, as well as the kinds of new commercial
and industrial development that are responsive to the City's economic needs.
The City’s Zoning Regulations are “intended to guide the development of the City in an orderly manner, implement the policies
of the General Plan, to protect and enhance the quality of the natural and built environment, promote the public health, safety,
and general welfare by regulating the use of land and building and the location and basic form of structures, and provide the
physical, environmental, economic, and social advantages that result from the orderly planned use of land resources” (Zoning
Regulations Section 17.02.020, Purpose and Authority).

a) The proposed Project is limited to an update to the City’s Zoning Regulations, pursuant to the City’s General Plan. The
proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that occur
pursuant to the proposed Project would be required to conform to all applicable regulations and standards of the updated
Zoning Regulations and the LUCE. The update does not include any actions that would result in the division of an
established community or neighborhood in the City, but rather provides the regulations that guide how future development
would be developed. Therefore, impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not allow new development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new impacts that have not been previously examined or adequately addressed in the LUCE
EIR Section 4.10 Land Use.
b) The proposed Zoning Regulations Update is specifically intended to achieve consistency with local and regional plans,
including the City’s General Plan. The proposed Zoning Regulations Update is one of the principal tools for implementing
the LUCE, and this specific comprehensive update does not go beyond providing the regulations necessary to implement
the policies and programs identified in the LUCE.
LUCE EIR Conclusion
As documented in the LUCE EIR, the ALUC found the LUCE update inconsistent with the ALUP. The City followed the
process called out in Public Utilities Code (PUC) Section 21676 et seq. by referring the LUCE update and implementation
to the ALUC for a determination of consistency with the ALUP. Following the ALUC’s determination of inconsistency
with the ALUP, the City complied with the requirements identified in the California State Aeronautics Act (SSA) (see, e.g.,
SAA 21676, 21676.5 and 21677), which provide the process for the City to overrule the ALUC decision. In association
with adoption of the LUCE and associated Airport Land Use Compatibility Report, and in compliance with the SAA, the
City Council approved an overrule of the ALUP, which allowed for development to occur pursuant to the General Plan and
adopted Specific Plans or existing Zoning Regulations Chapter 17.57 Airport Overlay Zone and associated Table 10 –
Airport Overlay Zone (AOZ) – Maximum Allowed Persons. The LUCE EIR determined that based on substantial evidence
in the record, that the overrule will not have a significant impact relative to safety, noise, airport land use compatibility or
any other component of the environment; therefore, the LUCE EIR characterizes the policy conflict between the LUCE
update and the ALUP as Class 3, less than significant. The LUCE EIR concluded that “the proposed LUCE Update would
conflict with the airport land use plan (ALUP). However, with the implementation of proposed LUCE Update policies and
implementing zoning regulations, potential land use conflicts are less than significant” (LUE EIR, Section 4.10 Land Use
[refer to Final EIR], Impact LU-1).
Proposed Zoning Regulations Update Analysis and Conclusions
Consistent with the analysis and conclusions of the LUCE EIR, implementation of the proposed Zoning Regulations
Update would facilitate development within the boundary of the ALUP and City Zoning Regulations AOZ. The proposed
Zoning Regulations Update has tentatively restructured this section of the Zoning Regulations as Chapter 17.64 and
includes clarifications to how density is to be calculated (consistent with the California Airport Land Use Planning
Handbook) and includes updates specific to the names of land uses, consistent with the remainder of the proposed Update
(refer to Article 2 of the proposed Project). The proposed Zoning Regulations Update would not modify the allowable
density for each use within identified Safety Zones (refer to Table 10 – Airport Overlay Zone (AOZ) – Maximum Allowed
Persons).
Table 1 below shows how the proposed Zoning Regulations Update would implement specific policies identified in the
LUCE:

Regulations
2.10. Updating & Enforcing Standards
2.10.1. Enforcing Standards. The City shall review, revise if
deemed necessary, and actively enforce noise, parking,
and property development and property-maintenance
standards.
This relates largely to enforcement.
Enforcement provisions are contained in
Chapter 1.24 of the SLO Municipal Code.
2.10.2. Property Maintenance Standards. The City shall
implement, and regularly review and update property-
maintenance regulations focused on proper enclosure of
trash, appearance of yards and buildings from the street,
and storage of vehicles.
Property maintenance standards have been
modified slightly to address concerns.
2.11. Multifamily Preferences and Standards
2.11.1. Preferences. The City shall evaluate student housing
preferences and consider revising development standards
to better meet them in multifamily housing near campus.
Mixed use regulations have been amended.
No other changes proposed at this time.
2.12. Downtown Residential Development. The City shall
adopt special development standards to guide addition of
dwellings within Downtown residential areas to
implement Policy 2.8. The following should be included
when evaluating new standards for this area:
A. Requirements that new dwellings on lots with existing
houses be above or behind the existing houses, and that
the added building area be modestly sized and of similar
architecture in comparison with the principal residences
on the site and in the surrounding area;
B. Requiring new buildings to reflect the mass and
spacing of existing, nearby buildings;
C. Requiring special parking and coverage standards;
D. Requiring minimum amounts of usable open space.
A and B. New setback and other standards
have been established for the R-1 and R-2
zones to address compatibility concerns.
C. Parking regulations have been revised to
reduce auto parking requirements generally
and encourage additional bike parking.
D. Standards included in Article 2.
2.13. Neighborhood Compatibility. The City will consider
new regulations, for Low-Density and Medium-Density
Residential areas, to require special review for (1)
incompatibly large houses, (2) replacement or infill
homes in existing neighborhoods, and (3) accessory
buildings with plumbing facilities allowing easy
conversion to illegal second dwellings. The City will
periodically update Community Design Guidelines for
larger homes, infill housing and accessory single-story
buildings.
New setback and other standards have been
established for the R-1 and R-2 zones to
address compatibility concerns. Also, edge
condition standards have been prepared to
address transitions between higher density
and lower density developments.
2.15. Residential Densities. The City will evaluate
alternatives to the current maximum number of dwelling
units per acre (based on bedroom count) and height,
parking, and setback standards, to regulate residential
building intensity, and bulk and mass. Floor area limits
will be considered.
Alternatives have been evaluated for
Downtown, with direction to have FAR
dictate for developments with units smaller
than 600 sf. Staff will implement this
direction as part of a subsequent amendment
once appropriate CEQA review has been
completed.
2.16. Use of Downtown Parking by Residents. The City
shall evaluate the potential to use portions of City-owned
This issue will be addressed as part of a

3.9. Zoning Regulations. The City shall amend its Zoning
Regulations to implement the changes included in the
2014 General Plan update program.
This update process and planned follow-up
amendments address this policy.
3.10. Noise Control. Zoning Regulations and Community
Design Guidelines will include measures such as the
following to prevent unacceptable noise exposure for
residential areas or other noise-sensitive uses: location
and shielding of mechanical equipment; location of truck
loading, trash collection areas, and loudspeakers; noise
attenuation measures along property lines.
New standards have been included to address
mechanical equipment noise along property
lines and location of loading and trash
collection areas.
3.13. Zoning Update for Visitor Services Uses. The City
shall review zoning regulations to consider allowing
visitor-service uses in office zones adjacent to
community commercial zones in the Downtown and
adjacent to Monterey Street between Johnson and Santa
Rosa.
Proposed overlay zone for Upper Monterey
from C-R to C-R-D (Downtown overlay)
3.14. Zoning Update for Emerging Technologies. The City
will investigate emerging technologies and trends to
evaluate whether updates to zoning regulations are
needed.
The use regulations have been simplified to
provide flexibility over time.
4.28. Allowing Efficiency Units and Variable Density in
Downtown. The City shall modify zoning regulations to
allow efficiency units and variable density in the
Downtown Core.
Alternatives have been evaluated for
Downtown, with direction to have FAR
dictate for developments with units smaller
than 600 sf. Staff will implement this
direction as part of a subsequent amendment
once appropriate CEQA review has been
completed.
4.32. Use Permit Requirements. The City shall incorporate
into its zoning regulations specific criteria for evaluating
use permits for bars/taverns, night clubs and late night
drinking establishments.
Standard conditions and findings have been
included for such uses (in Article 4).
7.16. Airport Overlay Zone. The City shall create an Airport
Overlay Zone to reflect the boundaries of the San Luis
Obispo County Regional Airport Land Use Plan within
the City limits. The purpose of the Airport Overlay Zone
is to codify airport compatibility criteria in areas for
which the City may override the Airport Land Use
Commission determination to ensure compliance with the
requirements of the California State Aeronautics Act
(Cal. Pub. Utilities Code, Section 21670, et. seq.) which
establishes statewide requirements for airport land use
compatibility planning, guidance from the California
Airport Land Use Planning Handbook, which is
published by the California Department of Transportation
Division of Aeronautics to support and amplify the State
Aeronautics Act requirements, and other related federal
and state requirements relating to airport land use
compatibility planning. Implementation of the
compatibility policies will be accomplished through the
Zoning Code.
This zone and accompanying regulation are
now in the Zoning Regulations.

7.17. Airport Land Use and Zoning Code. The City shall
update its Zoning Regulations to address allowable uses
and development standards for areas in which the City
may override a determination of inconsistency. Zoning
regulations shall be consistent with the requirements of
the State Aeronautics Act, use guidance from the
Caltrans Airport Land Use Planning Handbook and
comply with related state and federal requirements
relating to airport land use compatibility. These
development standards will include, but not limited to,
intensity and density limitations, identification of
prohibited uses, infill development, height limitations,
obstructions, and other hazards to flight, noise insulation
requirements, buyer awareness measures, nonconforming
uses and reconstruction and the process for airport
compatibility criteria reviews by the City consistent these
development standards.
The City is working with the County to
address consistency requirements.
7.18. Review of Local General Plan and implementing
Development Standards. Unless previously referred
and acted upon by the City, review of General and
Specific Plans and Amendments, Zoning ordinance or
amendments, or Building code changes within the San
Luis Obispo County Regional Airport Land Use Plan
boundary (Figure 9) shall include referral to the Airport
Land Use Commission as specified in Section 21676(b)
of the Public Utilities Code for a determination of
consistency with the San Luis Obispo County Airport
Land Use Plan.
Per State law, this provision is in the
regulations.
12.1. Zoning Regulations. Zoning Regulations consist of the
zoning map, lists of uses allowed in certain zones,
property-development standards such as maximum
building height and minimum parking, and procedures
intended to give the interests of development applicants
and other citizens fair consideration.
The updated Zoning Regulations achieve all
of these policy directives.
The proposed Project is limited to an update to the City’s Zoning Regulations, pursuant to the City’s General Plan. The
proposed Project, by itself, does not propose or authorize any development. Future land uses that occur pursuant to the
proposed Project would be required to conform to all applicable regulations and standards of the updated Zoning
Regulations and the General Plan. The update does not include any actions that would result in an incompatibility with an
adopted plan. Therefore, impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not allow new development in areas where such development is prohibited under the LUCE.
Therefore, consistent with the LUCE and Community Goals identified in the LUE, the proposed Zoning Regulations
includes standards and requirements that: facilitate protection of the environment, including hillsides, creeks, surface and
groundwater, soils, and air quality; include development and redevelopment standards that support a well-balanced
community; and maintain and where appropriate adapt the City form to preserve open space, create compact, mixed-use
neighborhoods that locate housing, jobs, recreation, and other daily needs in close proximity to one another, protect the
quality of life in established neighborhoods through compliance with proposed edge conditions regulations, and
encouraging multi-modal transportation. Therefore, there would be no new impacts that have not been previously examined

c) The City has eight Open Space Conservation Plans that guide protection, access, and restoration efforts within these areas
of the City’s Greenbelt: Agricultural Master Plan for Calle Joaquin Reserve; Bishop Peak Natural Reserve; Cerro San Luis
Conservation Plan; Irish Hills Conservation Plan; Johnson Ranch Conservation Plan; South Hills Conservation Plan;
Stenner Springs Natural Reserve Draft Conservation Plan; and Reservoir Canyon Natural Reserve Conservation Plan.
Riparian and wildlife corridors, wetlands, habitat, and other natural communities are addressed through policies in the
General Plan. Applicable COSE plans and policies include: 8.3.2 Open space buffers; 8.5.1 Public access; and 8.6.3
Required mitigation). Applicable LUE policies and programs include 6.1.1 Resource Planning; 6.3.2 Open Space Uses;
6.4.2 Development Limits; and 6.6.1 Creek and Wetlands Management Objectives.
LUCE EIR Conclusion
The LUCE EIR concluded that “the proposed Land Use Element Update would result in conflicts with applicable habitat
conservation plans or natural community conservation plans. With the implementation of proposed LUCE Update policies,
potential plan and policy conflict impacts are considered Class III, less than significant” (LUCE EIR, Section 4.10 Land
Use, Impact LU-3).
Proposed Zoning Regulations Update Analysis and Conclusions
The proposed Project is limited to an update to the City’s Zoning Regulations, pursuant to the City’s General Plan. The
proposed Project, by itself, does not propose or authorize any development. Future land uses that occur pursuant to the
proposed Project would be required to conform to all applicable regulations and standards of the updated Zoning
Regulations and the General Plan. The proposed Project supplements existing Zoning Regulations requirements applicable
to the preservation of natural resources by including additional and clarified regulations and mandatory findings related to
hillside development (see proposed Article 3, Hillside Development Standards) and allowing density reductions in the
Conservation and Open Space (C/OS) zone as necessary based on the extend of environmental resources. The Project does
not include any actions that would result in an incompatibility with an adopted plan. Based on compliance with the General
Plan and City Conservation Plans, potential impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not allow new development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new impacts that have not been previously examined or adequately addressed in LUCE EIR
Section 4.10 Land Use.
11. MINERAL RESOURCES. Would the project:
a) Result in the loss of availability of a known mineral resource
that would be of value to the region and the residents of the
state?

b) Result in the loss of availability of a locally-important mineral
resource recovery site delineated on a local general plan,

Evaluation
Native minerals are those occurring in the San Luis Obispo area that have, or are expected to have, economic value. Sand,
gravel and stone used in construction, and metal ores, are examples of economically valuable minerals. In the past, quarries and
mines in the San Luis Obispo area produced basaltic stone for masonry, “red rock” for road base and surfacing, and cinnabar,
an ore of mercury. State guidelines and rules aim for continued accessibility to native minerals, while avoiding significant harm
to the environment or human health from their extraction. In the 1980s, a petroleum company asked to explore City-owned land
in the Lopez Lake area. The request was denied based on the environmental qualities of the area. Since that time, no other such

requests have been received, and the City’s policy on mineral extraction within City limits has remained unchanged.
a), b) There are no mineral resource recovery sites in the City; therefore, the proposed Zoning Regulations Update would not
result in the loss of availability of a known mineral resource or mineral resource recovery site. Any future request would
be subject to the policies and programs of the General Plan and Municipal Code regulations. No impact would occur.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not allow new development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new impacts that have not been previously examined or adequately addressed in LUCE EIR

Evaluation
A number of noise‐sensitive land uses are present within the city, including various types of residential, schools, hospitals and
care facilities, parks and recreation areas, hotels and transient lodging, and place of worship and libraries. Based on ambient
noise level measurements conducted throughout the City during preparation of the LUCE EIR, major sources of noise include
traffic noise on major roadways, passing trains, and aircraft overflights. Roadway traffic from highways and major arterials is
the most significant source of noise affecting sensitive land uses in the City. LUCE EIR Section 4.11 Noise, Table 4.11‐1
Summary of Modeled Existing Roadway Traffic Noise Levels (refer to LUCE Final EIR) includes a summary of existing traffic
noise levels. As shown in the LUCE EIR, residential uses located within the 60 dBA (average decibel level) contour on several
road segments within the City are potentially exposed to noise levels above the 60 dBA Community Noise Equivalent Level
(CNEL) standard for residential land uses. In addition to traffic noise on roadways, freight and passenger trains passing through
the City contribute to community noise levels. Based on railroad noise modeling conducted for the LUCE EIR, noise levels
from the railroad would result in 69 dBA CNEL at 50 feet from the center of the track. Stationary sources in the community
include industrial facilities, as well as large institutions such as California Polytechnic State University. Aircraft overflights
from San Luis Obispo County Regional Airport also contribute to the noise environment. The Airport Land Use Compatibility
Report prepared in association with the LUCE EIR and adoption of the LUCE shows the location of the noise contours
associated with the forecasted operations from the Airport Master Plan EIR, with the appropriate fleet mix, and time of day
noise weighting (refer to Figure 6‐5 in the Johnson Aviation Airport Compatibility Report, November 2013). The LUCE EIR

states that no new residential uses are proposed within the 60 dB CNEL noise contours associated with forecasted airport
operations.
The City Noise Element contains a number of noise policies and standards, which are summarized in LUCE EIR, Section 4.11
Noise, including Table 4.11-2 Community Noise Exposure Levels and Table 4.11-3 Maximum Noise Exposure for Noise-
Sensitive Uses Due to Transportation Noise Sources. LUCE EIR Appendix J: Noise Modeling and LUCE Update Background
Report 6.10 Noise provide recent and future noise levels and associated noise contours based on updated noise modeling
conducted as part of the LUCE EIR. This updated information is currently used in place of the outdated noise levels and
contours presented in the City Noise Element. New development of noise‐sensitive land uses may be permitted only where
location or design allow the development to meet the standards identified for existing stationary noise sources (refer to the
Noise Element and LUCE EIR Section 4.11 Noise, Table 4.11‐4 Maximum Noise Exposure for Noise-Sensitive Uses Due to
Stationary Noise Sources). This policy does not apply to noise levels associated with agricultural operations. The Noise
Element also contains a number of policies that address procedures for noise mitigation, including specific treatments for sound
walls.
Chapter 9.12 of the City’s Municipal Code (Noise Control Ordinance) stipulates that construction or demolition activities that
create a noise disturbance across a residential or commercial property line are prohibited between the hours of 7:00 p.m. and
7:00 a.m., Monday through Saturday, and any time on Sundays or holidays (refer to Municipal Code Section 9.12.050). The
ordinance further states that, where technically and economically feasible, construction activities shall not exceed the standards
identified in LUCE EIR Section 4.11 Noise, Table 4.11‐5 Maximum Noise Levels for Properties Affected by Construction and
Demolition Noise. Municipal Code Section 9.12.050 prohibits operating or permitting the operation of any device that creates a
vibration which is above the vibration perception threshold of an individual at or beyond the property boundary of the source if
on private property or at 150 feet from the source if on a public space or public right‐of‐way.
Municipal Code Section 9.12.060 identifies exterior noise limits for noise generated by existing residential and nonresidential
properties (refer to LUCE EIR Section 4.11 Noise, Table 4.11‐6 Maximum Exterior Noise Limits). These noise level standards
are not to be exceeded more than 30 minutes in any one hour. The noise levels in LUCE EIR Table 4.11‐6 do not apply to
construction activities, which are covered under the noise levels summarized in LUCE EIR Table 4.11‐5. Based on the
Municipal Code, the maximum interior noise standard for multi‐family residential uses is 40 dBA from 10:00 p.m. to 7:00 a.m.
and 45 dBA from 7:00 a.m. to 10:00 p.m. These noise levels shall not be exceeded for a cumulative period of more than five
minutes in any hour or, the noise standard plus 5 dB for a cumulative period of more than one minute in any hour, or the noise
standard plus 10 db for any period of time. Municipal Code Section 9.12.080.A prohibits refuse collection between the hours of
7:00 p.m. and 6:30 a.m. within or adjacent to a residential area. In addition to the Municipal Code, the City uses the City of San
Luis Obispo Noise Guidebook as part of their regulatory program and to implement the Noise Element.
a) This analysis section addresses potential noise impacts, as compared to the compatibility and noise exposure standards in
the Noise Element, including: short-term noise generation, long-term noise generation due to transportation-related sources,
and long-term noise generation due to stationary sources.
LUCE EIR Conclusion
Short-term (Construction-related) Noise
The LUCE EIR states that construction activities associated with future development projects consistent with the LUCE
could include site preparation (e.g., excavation, grading), laying of concrete foundations, paving, equipment installation,
finishing, and cleanup. These activities typically involve the use of noise‐generating equipment such as cranes, excavators,
dozers, graders, dump trucks, generators, backhoes, compactors, and loaders. LUCE EIR Section 4.11 Noise, Table 4.11‐7
Typical Construction Equipment Noise Levels shows the maximum noise levels generated by the types of equipment and
activities that could be used during construction activities. During land development projects, the site preparation phase of
construction results in the most noise generation from the use of heavy‐duty equipment such as excavators, graders, dozers,
loaders, and trucks. Pile driving and blasting activities are unlikely to be used in most land development projects; however,
they are shown in the LUCE EIR Table 4.11 for reference. Based on the information provided in LUCE EIR Table 4.11‐7

and accounting for usage factors of individual pieces of equipment associated with a site preparation phase of construction,
construction levels of up to 85 dBA Lmax could occur as measured 50 feet from a construction site. These levels could
exceed the maximum construction noise levels permitted by the City’s Municipal Code adjacent to existing residential or
mixed residential/commercial land uses (see LUCE EIR, Section 4.11 Noise, Table 4.11‐5 Maximum Noise Levels for
Properties Affected by Construction and Demolition Noise).
The Noise Element establishes operational standards for siting of new land uses; however, it contains no policies or
programs that address the identification and mitigation of temporary construction noise generated by land development
projects on existing sensitive receptors. Municipal Code Chapter 9.12 (Noise Control Ordinance) sets forth maximum noise
levels that apply to existing properties that may be affected by construction and demolition activities. However, many
construction projects could still exceed the maximum levels permitted by the City’s ordinance, as noted above, particularly
in infill areas where adjacent land uses could be affected. Enforcement of the Noise Element and Noise Control Ordinance
would reduce impacts to the extent feasible; however, with the implementation of feasible construction noise reduction
measures and exemptions, construction activities could still exceed applicable standards especially if activities are near
existing receptors and/or occur during the nighttime. Thus, the LUCE EIR determined that short‐term construction noise
levels are considered Class I, significant and unavoidable.
The LUCE EIR concluded that “implementation of development projects under the proposed LUCE Update would involve
construction that could generate noise levels that exceed applicable standards for mobile construction equipment in the
City’s Noise Control Ordinance and result in temporary substantial increases in noise levels primarily from the use of
heavy‐duty construction equipment. Even with the incorporation of the proposed LUCE Update policies and existing City
policies, short‐term construction noise levels are considered Class I, significant and unavoidable” (LUCE EIR Section 4.11
Noise, Impact N-1: Short-Term Construction Noise Levels). Upon certification of the LUCE EIR and approval of the
LUCE Update, the City adopted a Statement of Overriding Considerations for this significant and unavoidable impact.
Proposed Zoning Regulations Update Analysis and Conclusions
Consistent with the analysis and conclusions in the LUCE EIR, implementation of the Zoning Regulations Update would
result in construction activity that generates noise levels exceeding applicable standards for mobile construction equipment
and would result in temporary substantial increases in noise levels during the use of heavy-duty construction equipment.
Future development is required to comply with the City Noise Element and Noise Control Ordinance; however, similar to
the conclusion of the LUCE EIR, potential short-term impacts related to construction activity would be significant and
unavoidable.
LUCE EIR Conclusion
Long-term Noise Exposure Due to Transportation-Related Noise Sources
The LUCE EIR states that implementation of the LUCE and associated development projects could result in exposure of
new sensitive receptors to existing transportation noise sources. Implementation of the LUCE would also generate
increases in traffic on local roadways, due to planned increases in population, housing, and employment; which would
increase overall traffic noise levels affecting both existing and new sensitive receptors. Single‐family residential
development, schools, libraries, hospitals, convalescent homes, and places of worship are considered the most
noise‐sensitive land uses. High‐density and mixed‐use residential, commercial, and industrial development is less
noise‐sensitive because activities are primarily indoors, and typically noise exposure can be reduced through design and
material choice (e.g., outdoor activity areas are located in courtyards surrounded by structures, materials with greater
insulation are used).
Roadway Traffic Noise. Existing and future traffic noise levels throughout the city were modeled during preparation of the
LUCE EIR to determine the anticipated traffic noise levels along major roadways. A complete list of roadway segments
and the modeled distances from the roadway centerline to the 55, 60, 65, and the 70 dBA Community Noise Equivalent
Level (CNEL)/Day‐night noise level (Ldn) contour and the noise level at 50 feet from the roadway centerline is provided in

LUCE EIR Technical Appendix J: Noise Modeling.
LUCE EIR Section 4.11 Noise, Table 4.11‐8 Modeled Changes in Traffic Noise Levels (2012 to 2035) shows the existing
(baseline) traffic noise levels on modeled roadways, projected 2035 traffic noise levels, and the change in noise levels at 50
feet from the modeled roadways. Based on the modeling conducted, future projected traffic volumes on modeled roadways
would result in traffic noise increases ranging from 1 to 10 dBA. The LUCE EIR determined that a noticeable increase in
noise (i.e., 3 dB or greater) would be considered a substantial increase in noise.
Railroad Traffic Noise. One existing railroad line owned by Union Pacific Railroad passes through the City and is used for
both freight and passenger rail service. Noise from railroads is generated primarily by diesel locomotive engines, warning
horns, and gate bells at railroad crossings. Other components of noise include diesel exhaust, cooling fans, and railroad car
wheel/rail interaction. Railroad noise modeling is shown in LUCE EIR Section 4.11 Noise, Table 4.11‐9 Summary of
Modeled Existing Railroad Noise Levels. The modeling summarizes the existing railroad noise levels at 50 feet from the
railroad centerline, along with approximate distances from the railroad centerlines to the 70 dB, 65 dB, 60 dB, and 55 dB
CNEL/Ldn noise contours. Pursuant to the LUCE, changes in land use could result in additional residential and mixed‐use
development along major corridors, within the downtown area, or in various areas near or adjacent to the railroad line.
Placement of new residential or other sensitive land uses in close proximity to this active railroad line could potentially
expose people to excessive noise levels.
The LUCE EIR concluded that “implementation of the proposed LUCE Update would increase traffic volumes and
associated noise levels along major transportation routes. In some instances, traffic‐related noise increases could be more
than 3 dB, the level typically audible to the human ear and; therefore, considered a substantial increase in noise. New
development associated with the proposed LUCE Update could also result in the siting of new sensitive receptors in close
proximity to transportation noise sources such as the railroad, with potential to exceed the land use compatibility and
transportation noise exposure standards in the existing Noise Element. However, because the City’s Noise Element
contains policies and programs that would address and mitigate potential site‐specific impacts for individual projects in the
future, this impact would be considered Class III, less than significant” (LUCE EIR Section 4.11 Noise, Impact N‐2
Long‐Term Roadway and Railroad Traffic Noise Levels).
Proposed Zoning Regulations Update Analysis and Conclusions
Consistent with the analysis and conclusions in the LUCE EIR, implementation of the Zoning Regulations Update would
result in increased traffic volumes and associated noise levels along major transportation routes. New development
associated with the proposed Project could also result in the siting of new sensitive receptors in close proximity to
transportation noise sources such as major roadways and the railroad, with potential to exceed the land use compatibility
and transportation noise exposure standards in the existing Noise Element. Future development is required to comply with
the City Noise Element and Noise Control Ordinance; therefore, potential impacts would be less than significant.
LUCE EIR Conclusion
Long-term Noise Exposure Due to Stationary Sources
Stationary (and area) sources include landscape and building maintenance activities, stationary mechanical equipment (e.g.,
pumps, generators, HVAC units), garbage collection activities, commercial and industrial activities, and other stationary
and area sources such as people’s voices, amplified music, and public address systems.
The LUCE EIR concluded that “implementation of the proposed LUCE Update could increase stationary source noise
levels from new development. New development associated with the proposed LUCE Update could also result in the siting
of new sensitive receptors in close proximity to these source types, with potential to exceed the land use compatibility and
stationary noise exposure standards in the existing Noise Element. However, because the City’s Noise Element contains
policies and programs that would address and mitigate potential site‐specific impacts for individual projects in the future,
this impact would be considered Class III, less than significant” (LUCE EIR Section 4.11 Noise, Impact N-3 Exposure of

Noise Sensitive Receptors to Stationary Sources).
Proposed Zoning Regulations Update Analysis and Conclusions
Consistent with the analysis and conclusions of the LUCE EIR, implementation of development pursuant to the proposed
Zoning Regulations Update could increase stationary source noise levels from new development. New development could
also result in the siting of new sensitive receptors in close proximity to these source types, with the potential to exceed the
land use compatibility and stationary noise exposure standards in the Noise Element. However, the City’s Noise Element
contains policies that apply to new stationary sources, and, similarly, LUCE policies would serve to mitigate potential
increases in stationary noise that could occur as a result of overall development through 2035.
Implementation of the proposed Project could also introduce new sensitive land uses in close proximity to existing
stationary noise sources that could exceed applicable thresholds contained in the City’s Noise Element, similar to the
analysis and conclusions identified in the LUCE EIR. Noise Element policies and standards require all new development to
comply with the City’s adopted noise standards, noise mitigation procedures, and sensitive land use siting policies.
Site‐specific noise studies would require mitigation measures, if necessary, to ensure that development meets noise
standards. Therefore, implementation of the Zoning Regulations Update would not expose people to excessive noise levels
from stationary sources.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable regulations and standards of the
Municipal Code and Noise Element, which would ensure that future new land uses are designed to minimize construction-
related, operational, and stationary noise levels. Similar to the determination in the LUCE EIR and associated Statement of
Overriding Considerations, short-term impacts resulting from construction-related noise pursuant to the proposed Zoning
Regulations Update would be significant and unavoidable. Long-term impacts associated with increases in transportation-
related noise, development of noise-sensitive uses near transportation corridors, and increases in stationary noise sources
would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not make changes to the City’s existing Noise Ordinance. Additionally, the proposed Project
would not allow new development in areas where such development is prohibited under the LUCE. Therefore, there would
be no new impacts that have not been previously examined or adequately addressed in LUCE EIR Section 4.11 Noise.
b) Ground vibration may result from short‐term construction activities as well as long‐term exposure from transportation noise
sources (i.e., passenger trains, freight trains, buses). Construction activities have the potential to result in varying degrees of
temporary ground vibration, depending on the specific construction equipment used and activities involved. Vibration
generated by construction equipment spreads through the ground and diminishes with increases in distance.
Construction‐related ground vibration is normally associated with impact equipment such as pile drivers, jackhammers, and
the operation of some heavy‐duty construction equipment, such as dozers and trucks. Blasting activities also generate
relatively high levels of ground vibration. LUCE EIR Section 4.11 Noise, Table 4.11‐10 Representative Ground Vibration
and Ground Noise Levels for Construction Equipment displays ground vibration levels for typical construction equipment.
The effects of ground vibration may be imperceptible at the lowest levels, result in low rumbling sounds and detectable
vibrations at moderate levels, and high levels of vibration can cause sleep disturbance in places where people normally
sleep or annoyance in buildings that are primarily used for daytime functions and sleeping. Ground vibration can also
potentially damage the foundations and exteriors of existing structures even if it does not result in a negative human
response. Pile driving and blasting activities produce the highest levels of ground vibration, as shown in LUCE EIR Table
4.11‐10 and can result in structural damage to existing buildings.

The LUCE EIR concluded that “implementation of the proposed LUCE Update could increase exposure to vibration levels.
However, because the City’s ordinance contains and that these sources (existing and proposed) would be anticipated to be
minor, this impact would be considered Class III, less than significant” (LUCE EIR Section 4.11 Noise, Impact N-5
Exposure to Excessive Vibration Levels).
Proposed Zoning Regulations Update Analysis and Conclusions
Consistent with the analysis and conclusions of the LUCE EIR, future development pursuant to the Zoning Regulations
Update would occur in primarily urban settings where land is already disturbed and; therefore, would not be anticipated to
require blasting, which is typically used to remove unwanted rock or earth. However, it is possible that pile driving could
occur during building construction. The Zoning Regulations Update could facilitate the construction of sensitive land uses
within portions of the City where known vibration sources exist, primarily in areas located along the existing active
railroad corridors (a primary ground vibration source within the city). With regards to vibration impacts on new
development near railroads, human disturbance is the primary concern. Vibration levels from trains passing would not
result in structural damage to new development. As documented in the LUCE EIR, Section 4.11 Noise, proposed
development within 80 feet of an existing railroad centerline could exceed the recommended threshold for human
disturbance of 80 VdB for sensitive receptors that are exposed to an infrequent amount of vibration events.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable regulations and standards that
address vibration, including requirements in the City’s Noise Ordinance that address construction-related vibration. Future
development shall also comply with existing performance standards identified in the Zoning Regulations, which state that
“no activity shall be conducted which causes ground vibrations perceptible at the property line” (current Zoning
Regulations Section 17.18.020, proposed Zoning Regulations Section 17.74.110, Vibration). In addition, pursuant to
CEQA, future new land uses that occur pursuant to the proposed Zoning Regulations Update would be subject to their own
environmental review on a project-by-project basis to assess impacts related to groundborne vibration. Therefore, potential
impacts related to vibration would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not allow new development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new vibration impacts that have not been previously examined or adequately addressed in
LUCE EIR Section 4.11 Noise.
c), d) LUCE EIR Conclusion and Proposed Zoning Regulations Update Analysis and Conclusion
Overall, development under the LUCE and Zoning Regulations Update would increase development intensity within the
city limits, as well as undeveloped areas to a more built environment, thereby resulting in the generation of noise impacts
as experienced by sensitive receptors. As noted above, the General Plan and Municipal Code protect sensitive receptors
from noise impacts through policies and plan review. Adherence to these requirements would reduce any long-term
impacts from buildout, including potential increases in overall ambient noise levels. With the implementation of feasible
construction noise reduction measures and exemptions, short term construction activities could still exceed applicable
standards especially if activities are near existing receptors and/or occur during the nighttime. Thus, consistent with the
LUCE EIR, cumulative short‐term construction noise levels remain Class I, significant and unavoidable (LUCE EIR
Section 4.11, Cumulative Impacts).
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable regulations and standards of the
Municipal Code and Noise Element, which would ensure that future new land uses are designed to minimize construction-
related and operational noise levels. Similar to the determination in the LUCE EIR and associated Statement of Overriding
Considerations, cumulative noise-related impacts pursuant to the proposed Zoning Regulations Update would be
significant and unavoidable.

Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not make changes to the City’s existing Noise Ordinance. Additionally, the proposed Project
would not allow new development in areas where such development is prohibited under the LUCE. Therefore, there would
be no new impacts that have not been previously examined or adequately addressed in LUCE EIR Section 4.11 Noise.
e), f) The ALUP establishes noise compatibility policies for sensitive land uses within the projected 55 and 60 dBA CNEL
airport noise contours associated with the hypothetical maximum use of both runways. The ALUP restricts extremely noise
sensitive land uses within the 60 dBA CNEL airport noise contour and requires mitigation measures for moderately
sensitive land uses within the 60 dBA CNEL airport noise contour. As summarized in this Initial Study (see Section 10
Land Use and Planning) and as described in detail in the LUCE EIR, the City approved an overrule of the ALUC’s
determination of consistency with the ALUP. The LUCE EIR determined that based on substantial evidence in the record,
that the overrule will not have a significant impact relative to safety, noise, airport land use compatibility or any other
component of the environment. In addition, two Specific Plan areas are located proximate to the airport. The Margarita
Area Specific Plan area is located directly north of the Airport Area Specific Plan area and northwest of the Airport, while
the Airport Area lies immediately adjacent to and north of the Airport. Development within these areas are subject to the
policies, standards, and requirements identified in these Specific Plans.
LUCE EIR Conclusion
The LUCE EIR concluded that “implementation of the proposed LUCE Update would result in the designation of
noise‐sensitive land uses located within or near the 55 dBA and 60 dBA noise contours of the San Luis Obispo County
Regional Airport Land Use Plan. This could result in exposure of people to excessive noise levels. However, with the
incorporation of the proposed LUCE Update policies that address airport noise compatibility and consistency with the
adopted ALUP, this impact would be considered Class III, less than significant” (LUCE EIR Section 4.11, Impact N-4
Airport Noise Exposure).
Proposed Zoning Regulations Update Analysis and Conclusions
Implementation of the proposed Zoning Regulations Update would result in development occurring within the boundaries
of the ALUP and City AOZ. Consistent with the analysis and conclusions of the LUCE EIR, based on compliance with the
General Plan and proposed clarifications to the Airport Overly Zone section of the Zoning Regulations, potential impacts
would be less than significant.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable regulations and standards of the
Municipal Code, General Plan, and Specific Plans (as applicable). Therefore, the proposed Zoning Regulations Update
would not expose people to significant levels of airport noise. Impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not allow new development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new impacts related to noise generated by airport operations that have not been previously
examined or adequately addressed in the LUCE EIR (Section 4.11 Noise).

Evaluation
As documented in the LUCE EIR, as of January 2013, the City has a population of 45,541, and is expected to have a population
increase of 4,613 people by 2035. Over the past 30 years, the population of the City has grown at an average rate of about one
percent per year, with periods of faster or slower growth reflecting national and statewide economic cycles. At the beginning of
2013, the City had 20,697 housing units. According to the City’s General Plan Annual Report 2017, the total population in
2017 was 46,724 and the total housing units was 21,286. LUE Policy 1.11.2 Residential Growth Rate, states that the City shall
manage the growth of the city's housing supply so that it does not exceed one percent per year, on average, based on thresholds
established by Land Use Element Table 3 [One Percent City Population Growth Projection]. This rate of growth may continue
so long as the City's basic service capacity is assured. Based on the Community Development Department’s running total of
residential construction permits, as shown in General Plan Annual Report 2017 Table 6, the annual growth rate in 2017 was
0.53 percent, which includes new single-family and multi-family residential construction. This is well within the limit of the
one percent annual residential growth rate identified in the Land Use Element. The five-year average growth rate also remained
below one percent at 0.46 percent.
a) LUCE EIR Conclusion
The LUCE EIR concluded that “the LUCE Update would not result in residential unit development or associated
population growth that exceeds an adopted average annual growth rate threshold. Potential population and housing impacts
are considered Class III, less than significant” (LUCE EIR, Section 4.12 Population and Housing, Impact PH‐1).
Proposed Zoning Regulations Update Analysis and Conclusions
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable standards (such as maximum
density) of the Zoning Regulations, as updated, and the LUCE, including identified growth rates. Therefore, the proposed
Zoning Regulations Update would not induce substantial population growth. Impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not allow new development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new impacts that have not been previously examined or adequately addressed in LUCE EIR,
Section 4.12 Population and Housing.
b), c) The City’s Housing Element includes several goals, policies, and programs specific to the retention of existing housing
within the City. Development pursuant to the Zoning Regulations Update is required to be consistent with City Housing
Element Goal 3 Housing Conservation: “Conserve existing housing and prevent the loss of safe housing and the
displacement of current occupants”. Housing Element Program 3.10 states that “continue to encourage the creation of
dwellings in the Downtown Core (C-D Zone) and the Downtown Planning Area by continuing the "no net housing loss"
program, consistent with Chapter 17.86 (Downtown Housing Conversion Regulations) of the Zoning Regulations”. The
proposed Zoning Regulations retain the statement that “development projects within the Downtown Planning Area shall
not result in a net housing loss.” The proposed Zoning Regulations Update, by itself, does not propose or authorize any
development. Future land uses that occur pursuant to the proposed Project would be required to conform to all applicable
federal, state, and local regulations that restrict housing loss and address tenant displacement. Based on compliance with
the Housing Element, and implementation of the Zoning Regulations, impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The

The San Luis Obispo Fire Department (SLOFD) provides fire and emergency services to the City of San Luis Obispo. The Fire
Department is organized into five divisions: Emergency Operations, Fire Prevention and Life Safety, Training and Equipment,
Administrative, and Support Services. In addition to providing fire and emergency services to the city, SLOFD maintains an
Emergency Services Contract with Cal Poly. Under the current contract, SLOFD provides fire and emergency services to the
university in return for a set annual fee. SLOFD operates out of four fire stations located throughout the City.
The San Luis Obispo Police Department (SLOPD) provides police protection services within the city limits. SLOPD is
responsible for responding to calls for service, investigating crimes and arresting offenders, enforcing traffic and other laws,
and promoting community safety through crime prevention and school‐safety patrols. The Police Department consists of two
bureaus, Administration and Operations, each of which has four divisions. The Police Department operates out of one main
facility located at 1042 Walnut Street and a small additional office at 1016 Walnut Street. In July 2010, a new Emergency
Communications Center opened at Fire Station One. The Emergency Communications Center provides dispatch for the Police
Department and Fire Department. Program 9.3C of the Safety Element establishes a 30% available time objective for patrol
response. “Available time” is the fraction of total time that a patrol unit is not previously assigned and is intended for use to
conduct proactive enforcement, community policing or to assist with neighborhood wellness initiatives. The San Luis Obispo
County Sheriff’s Department provides law enforcement services to areas outside the city but within the LUCE Planning
Subarea. The Cal Poly Police Department provides police protection on campus. The California Highway Patrol (CHP) also
provides law enforcement services within the LUCE Planning Subarea, primarily along state highways.
The San Luis Coastal Unified School District (SLCUSD) serves an area between the coast and the Los Padres National Forest,
and from Morro Bay to the north and Arroyo Grande to the south. In total, the District operates ten elementary schools, two
middle schools, two high schools, one continuation high school, and an adult education facility. In addition to the K‐12
educational program, the SLCUSD offers a variety of additional educational programs, including: cooperative preschool,
preschool early education, and parent participation. Within the San Luis Obispo LUCE Planning Subarea, the District operates
six elementary schools, one middle school, one high school, and one continuation high school. There are six private schools
located within the LUCE SOI Planning Subarea that provide preschool, primary, secondary, and high school educational
services to residents based on individually set criteria (e.g., academic performance, religious affiliation). California Polytechnic
State University San Luis Obispo and Cuesta College provide college education services.
There are 26 parks in the city, consisting of eight community parks, ten neighborhood parks, and eight mini-parks. There are
also six joint use facilities, and several recreation centers and special facilities (e.g., Damon Garcia Sports Fields and the SLO
Swim Center). There is currently approximately 151.65 acres of parkland in the city, of which 33.53 acres are neighborhood
parks. In addition to developed parks, the City owns or manages over 6,970 acres of open space within and adjacent to San Luis
Obispo, some of which provide trails that accommodate hiking and mountain biking. LUCE EIR Section 4.14 Recreation

facilities in San Luis Obispo.
a) LUCE EIR Conclusion
As determined in the LUCE EIR, new residential and non‐residential development facilitated by the LUE would place
additional service demands on the SLOFD. Increased service demands would have the potential to result in a significant
environmental impact if new or physically altered fire service facilities would be required to ensure that the City’s four-
minute response standard was achieved.
The LUCE EIR concluded that “buildout of the proposed Land Use Element would increase the demand for fire protection
services by increasing population and the number of structures in the city. This is a Class II, potentially significant but
mitigable impact” (LUCE EIR, Section 4.13 Public Services, Impact PS-1). The recommended mitigation identified in the
LUCE EIR was incorporated into the Safety Element, which includes the following policy as required pursuant to
certification of the LUCE EIR: “Development shall be approved only when adequate fire suppression services and facilities
are available or will be made available concurrent with development, considering the setting, type, intensity, and form of
the proposed development”.
Proposed Zoning Regulations Update Analysis and Conclusions
Consistent with the LUCE EIR, implementation of development pursuant to the proposed Zoning Regulations would result
in additional residential and non-residential development that would be served by SLOFD. As future development would
be subject to General Plan policies, including the modified measure from the LUCE EIR that was incorporated into the
Safety Element, implementation of the proposed Zoning Regulations Update would result in less than significant adverse
physical impacts associated with the provision of new or altered facilities needed to achieve consistency with the City’s fire
response standard.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be evaluated by the City as part of the planning and development review
process to determine the level of and demand for fire protection services that would be generated by each project.
Additionally, all new land uses would be required to conform to all applicable federal, state, and local regulations that
address fire safety, including the City Municipal Code, CBC, and Fire Code. Therefore, the proposed Zoning Regulations
Update would not result in substantial adverse impacts on fire services. Impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Zoning Regulations Update would not allow new development in areas where such development is prohibited
under the LUCE. Therefore, there would be no new impacts that have not been previously examined or adequately
addressed in LUCE EIR Section 4.13 Public Services.
b) LUCE EIR Conclusion
The LUCE EIR states that new residential and non‐residential development facilitated by the LUE would place additional
service demands on the SLOPD. Increased service demands would have the potential to result in a significant
environmental impact if new or physically altered law enforcement service facilities would be required. Based on the
population estimates identified in the LUCE EIR, and if additional officers were hired commensurate with future
population growth facilitated by the LUE, a total of 74 officers, an increase of seventeen officers compared to baseline
conditions identified in the LUCE EIR, would be required to retain the existing officer to population ratio of 1.27. Space to
house police personnel and equipment is currently fully subscribed. Should a substantial number of officers be hired in the
future, reconfiguration, reconstruction or new construction of facilities may be needed to accommodate them. If a new or
additional facility is constructed in a new location, changes to response time could result. Adverse physical impacts
associated with the provision of new or altered facilities needed to maintain the existing ratio of officers to the population

served are unlikely as any new or reconstructed facility would be required to meet community design guidelines, and its
location would need to meet the response time needs of the community. As of June 2018, the City is evaluating the possible
construction of a new Police Department in the City. The LUCE EIR states that “the proposed LUCE Update would not
result in substantial adverse physical impacts associated with the provision of new or altered facilities related to law
enforcement services” (LUCE EIR, Section 4.13 Public Services).
The LUCE EIR concluded that “buildout of the proposed Land Use Element Update would increase the demand for police
protection services by increasing population and development in the city. This is a Class III, less than significant impact.
The proposed LUCE Update would result in less than significant environmental impacts related to law enforcement
services and no mitigation measures are required” (LUCE EIR, Section 4.13 Public Services Impact PS‐2).
Proposed Zoning Regulations Update Analysis and Conclusions
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be evaluated by the City as part of the planning and development review
process to determine the level of and demand for police protection services that would be generated by each project.
Additionally, all new land uses would be required to conform to all applicable federal, state, and local regulations that
address public safety, including the City Municipal Code and CBC. Therefore, the proposed Zoning Regulations Update
would not result in substantial adverse impacts on police services. Impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Zoning Regulations Update would not allow new development in areas where such development is prohibited
under the LUCE. Therefore, there would be no new impacts that have not been previously examined or adequately
addressed in LUCE EIR Section 4.13 Public Services.
c) LUCE EIR Conclusion
The LUCE EIR determined that providing new residential units would increase the population of the City, which would
result in additional school‐age children attending the City’s public schools. New student generation rates for single‐ and
multi‐family residential units are depicted on LUCE EIR Section 4.13 Public Services, Table 4.13‐3 Student Generation
Rates. LUCE EIR Chapter 2, Project Description, Table 2.4‐3 Total Future Development Capacity within the Planning
Subarea indicates that buildout of the LUE could result in the development of approximately 4,904 new dwelling units in
the city, consisting of 2,420 single‐family dwellings and 2,484 multi‐family units. Projected new student generation that
would result from buildout of the proposed LUE is provided on LUCE EIR Section 4.13 Public Services, Table 4.13‐4
Proposed Land Use Element Buildout Student Generation. Based on student generation rates provided by SLCUSD, the
LUE would have the potential to generate approximately 911 additional students by the year 2035, which is anticipated to
be the buildout year of the LUE. The additional students generated by buildout of the proposed LUE could result in
over‐capacity conditions at certain schools located in the LUCE Planning Area. The additional students could result in the
need for the expansion of existing schools and/or the installation of portable classrooms at existing school sites; however, it
is unlikely that providing additional classrooms at existing school sites would result in significant environmental impacts.
The LUCE EIR concluded that “buildout of the proposed Land Use Element Update would increase enrollment in public
schools by increasing the population of the city. This is a Class III, less than significant impact” (LUCE EIR, Section 4.13
Public Services, Impact PS‐3).
Proposed Zoning Regulations Update Analysis and Conclusions
Consistent with the conclusions of the LUCE EIR, should new school facilities be required to accommodate additional
student populations resulting from build-out of the LUCE pursuant to the proposed Zoning Regulations Update, short-term
impacts associated with construction are generally reduced to a less than significant level with the implementation of site

design measures and compliance with applicable regulations. Site‐specific evaluations of any proposed new or expanded
schools would be required, however, it is expected that potential physical impacts associated with the provision of new or
altered school facilities needed to serve additional school‐age children residing in the additional 4,904 residential units that
could be developed under the proposed LUE and Zoning Regulations Update would not be significant.
In addition, Senate Bill 50 (Government Code Section 65970) implemented school impact fee reforms in 1998 by
amending the laws governing developer fees and school mitigation. Pursuant to SB 50, future development projects would
be required to pay school impact fees established to offset potential impacts on school facilities. Therefore, although
implementation of the Zoning Regulations Update would result in additional students and could result in or contribute to
over‐capacity at individual schools, payment of the fees mandated under SB 50 is the mitigation measure prescribed by the
statute, and payment of the fees is deemed full and complete mitigation.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Zoning Regulations Update would be required to pay developer fees per SB50 to mitigate
impacts on schools. Therefore, the proposed Project would not result in substantial adverse impacts on schools. Impacts
would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not allow new development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new impacts that have not been previously examined or adequately addressed in LUCE EIR
Section 4.13 Public Services.
d), e) The City Parks and Recreation Element and Master Plan includes a park standard that requires the City to develop and
maintain 10 acres of parkland per 1,000 residents, with at least five of each 10 acres developed as neighborhood parks. The
LUCE EIR determined that based on existing population and parks acreage conditions, the city needs an additional 303
acres of park land, of which 195 acres should be neighborhood parks, to meet its per capita parkland standard.
LUCE EIR Conclusion
The LUCE EIR determined that based on a potential buildout population of 58,626 and a total of 204 acres of parkland, the
amount of per capita parkland in the city would be 3.44 acres per 1,000 residents, which is more per capita parkland than
the existing 3.32 acres of parkland for each 1,000 residents currently provided. As such, implementation of the LUCE
would result in a slightly improved parkland per capita ratio when compared to existing conditions. To achieve the City’s
parkland standard of 10 acres per 1,000 residents under proposed LUCE buildout conditions, approximately 586 acres of
parkland would be required in the city. The increase in per capita parkland proposed by the LUCE would incrementally
improve the existing condition in which the City’s per capita parkland standard is not achieved. In addition, the increase in
per capita parkland would minimize the potential for an adverse increase in the use of existing parks or other recreational
facilities such that substantial physical deterioration of the existing facilities would occur or be accelerated.
The LUCE EIR concluded that “buildout of the proposed LUCE Update would increase the population of the city and
would facilitate the development of additional parkland. Buildout of the proposed LUCE Update would result in a small
increase in total per capita parkland in the city when compared to existing conditions. Although the LUCE Update would
not comply with the City’s per capita parkland standard, this would not result in a physical effect. Therefore the LUCE
Update would result in a Class III, less than significant environmental impact related to the increased use of existing park
and recreation facilities” (LUCE EIR Section 4.14 Recreation, Impact REC-1).
Proposed Zoning Regulations Update Analysis and Conclusions
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Zoning Regulations Update may be subject to the payment of park fees, if such fees are

adopted by the City. In addition, the Quimby Act (1975) gives cities and counties the authority, by ordinance, to require the
dedication of land or payment of in‐lieu fees, or a combination of both, for park and recreation purposes as a condition of
approval of a tract map or parcel map. The Quimby Act allows fees to be collected for up to five acres of parkland per
1,000 residents. The Orcutt Area and Margarita Area Specific Plans have associated parkland impact fees to ensure
dedication and development of parkland occurs. However, development in other areas of the City is not subject to park fees
other than through Quimby Act fees collected with subdivisions. Furthermore, as part of the planning and development
review process, all new residential development projects would be evaluated on a case-by-case basis to determine the level
of and demand for parks and common open space that would be generated by a specific project. Therefore, the proposed
Zoning Regulations Update would not result in substantial adverse impacts on parks. Impacts would be less than
significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not allow new development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new impacts that have not been previously examined or adequately addressed in LUCE EIR

Special Facilities and Figure 4.14‐1 Parks Locations describe the type, location, and amenities provided by parks and special
facilities in San Luis Obispo.
a), b) LUCE EIR Conclusion
The construction and use of park facilities adjacent to residential areas has the potential to result in significant
environmental impacts related to issues such as traffic, noise, dust generation and emissions, night lighting and land use
compatibility. Future development under the LUCE will be required to comply with local, State, and Federal laws and
policies, and all applicable permitting requirements of the regulatory and oversight agencies intended to address potential
impacts resulting from future development of parks facilities. Applicable LUE policies include 2.3.2 Separation and
Buffering, which states that “the City shall seek to protect Residential areas from incompatible and detrimental non-
residential activities and facilities” and Policy 12.9 Environmental Review.
The LUCE EIR concluded that “buildout of the proposed Land Use Element would potentially provide up to 52.4 acres of
new park facilities in the city. The construction and use of the proposed parks would have the potential to result in
significant environmental impacts. This is considered a Class III impact, less than significant” (LUCE EIR, Section 4.14
Recreation, Impact REC‐2).

Proposed Zoning Regulations Update Analysis and Conclusions
Consistent with the analysis and conclusions of the LUCE EIR, existing General Plan policies applicable to future park
project design would substantially reduce the potential for park‐related environmental impacts as a result of development
occurring pursuant to the proposed Zoning Regulations Update. In addition, subsequent CEQA review would identify
project‐specific impacts and provide measures to reduce potential impacts to the extent possible. Furthermore, pending
preparation of a Parks and Recreation Master Plan and General Plan Element Update (recently authorized by the City
Council), most of the future parkland to be provided in the city would be constructed as part of the buildout of previously
approved (Margarita and Orcutt) or proposed (San Luis Ranch, Avila Ranch, Madonna) Specific Plans, which would
facilitate park planning and design opportunities to minimize environmental impacts and land use conflicts. Therefore,
potential adverse physical effects on the environment resulting from future park development and use would be reduced to
a less than significant level through the implementation of proposed policy and project‐specific CEQA requirements.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Zoning Regulations Update may be subject to the payment of park fees, if such fees are
adopted by the City. Furthermore, as part of the planning and development review process, all new residential development
projects would be evaluated on a case-by-case basis to determine the level of and demand for parks and common open
space that would be generated by the project, in addition to potential impacts resulting from the development and operation
of additional parkland. Therefore, the proposed Zoning Regulations Update would not result in substantial adverse impacts
on parks. Impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Project would not allow new development in areas where such development is prohibited under the LUCE.
Therefore, there would be no new impacts that have not been previously examined or adequately addressed in LUCE EIR

The City is accessed primarily by roadways including US 101, State Route (SR) 1 and SR 227. Routes of regional
significance providing access include Los Osos Valley Road, Foothill Road, Broad Street, O’Connor Way, Prefumo
Canyon Road, South Higuera Street and Orcutt Road. The city is accessed by air via the San Luis Obispo County Regional
Airport or by rail via Amtrak’s Pacific Surfliner and Coast Starlight routes. Additional modes of transportation include City
bikepaths and bikelanes and SLO Transit (refer to LUCE EIR Section 4.15 Transportation and Circulation, Figure 4.15‐1
City of San Luis Obispo Roads, Airport and Rail, Figure 4.15‐2 City of San Luis Obispo Roads, Transit, and Figure 4.15‐3
City of San Luis Obispo Bicycle System). LUCE EIR Section 4.15 Transportation and Circulation, Table 4.15-2 Local
Roadway LOS (Per ADT Threshold) shows the properties of local roadways and the baseline level of service (LOS) as
determined by the transportation analysis conducted for the LUCE EIR. LUCE EIR Section 4.15 Transportation and
Circulation also discusses neighborhood traffic management and roadway operations.
a), b) LUCE EIR Conclusion
Roadways and Intersections. Based on the LUCE EIR, future implementation of the LUCE would have the potential to
result in significant impacts related to roadway and intersection operations. LUCE EIR Section 4.15 Transportation and
Circulation, Table 4.15‐6 US‐101 Proposed Project AM Peak‐Hour LOS (Post Miles from South to North), Table 4.15-7
US‐101 Proposed Project PM Peak‐Hour LOS (Post Miles from South to North), and Table 4.15-8 Cumulative Local
Roadway LOS (Using FDOT Procedures) show the potential changes to LOS. As documented in the LUCE EIR, the
following eight roadway segments would experience significant impacts due to increases in volumes: Broad (S/South,
South – Orcutt, Orcutt – Tank Farm Road and Buckley – South City Limit); Chorro (Foothill – Lincoln; Los Osos Valley
Road (just west of the City Limits); and Prado (US 101 – Higuera and Higuera – Broad). As shown in LUCE EIR Section
4.15 Transportation and Circulation, Table 4.15-9 2035 Intersection LOS Summary – LOS E/F, a total of eleven
intersections would operate at unacceptable conditions during the AM and/or PM peak hours, including: Grand and Slack;
California and Taft; Grand and US 101 SB on‐ramp/Loomis; San Luis and California; Higuera & Tank Farm; Broad and
High; Broad and Rockview; Broad and Capitolio; Johnson and Orcutt; Broad and Tank Farm; and Broad and Airport.
The LUCE EIR concluded that “development and street network changes under the LUCE Update will cause roadways
currently operating at LOS D or better to deteriorate to LOS E or F, in downtown San Luis Obispo, roadways operating at
LOS E or better will deteriorate to LOS F, or will add additional traffic to roadways operating at LOS E (outside of
downtown) or F (in downtown). Impact is considered to be Class I, significant and unavoidable” (LUCE EIR Section 4.15
Transportation and Circulation, Impact CIR‐1). Upon certification of the LUCE EIR and approval of the LUCE Update, the
City adopted a Statement of Overriding Considerations for this significant and unavoidable impact.
The LUCE EIR also concluded that “development and street network changes under the LUCE Update will cause
intersections currently operating at LOS D or better to deteriorate to LOS E or F, in downtown San Luis Obispo,
intersections operating at LOS E or better will deteriorate to LOS F, or will add additional traffic to intersections operating
at LOS E (outside of downtown) or F (in downtown). Impact is considered to be Class I, significant and unavoidable”
(LUCE EIR Section 4.15 Transportation and Circulation, Impact CIR‐2). Upon certification of the LUCE EIR and approval
of the LUCE Update, the City adopted a Statement of Overriding Considerations for this significant and unavoidable
impact.
Proposed Zoning Regulations Update Analysis and Conclusions
Implementation of development pursuant to the proposed Zoning Regulations Update, including proposed modifications to
allowable density in the R-3 zone, future development within the Upper Monterey Downtown Overlay zone, and
establishment of minimum dwelling units on multi-family residential (R-2, R-3, and R-4) and office zoned lots, would have
the potential to result in significant impacts related to operations of City roadways and key intersections, as identified in the
LUCE EIR. Future development shall be consistent with the Circulation Element, which includes multiple policies
addressing issues including, but not limited to, congestion, multi-modal and alternative transportation, growth management
and roadway expansions, peak hour and daily traffic, and transportation funding. The Circulation Element also includes

policies that support and encourage use of alternative modes, which would result in a shift in mode of travel, and reduction
in the traffic volumes on city streets. While the potential addition of traffic related to City build-out pursuant the General
Plan and Zoning Regulations would be considered significant, compliance with Circulation Element policies could reduce
volumes; however, further reduction of volumes would be necessary to reduce impacts to less than significant levels (as
stated in the LUCE EIR). Therefore, this impact remains significant and unavoidable, as determined in the LUCE EIR.
LUCE EIR Conclusion
Freeway Operations. Consistent with the determinations of the LUCE EIR, future implementation of the LUCE pursuant to
the proposed Zoning Regulations Update has the potential to result in significant impacts on freeway facilities. The LUCE
EIR concluded that “development under the LUCE Update will increase traffic on freeway facilities. Impact is considered
to be Class I, significant and unavoidable” (LUCE EIR Section 4.15 Transportation and Circulation, Impact CIR‐3). Upon
certification of the LUCE EIR and approval of the LUCE Update, the City adopted a Statement of Overriding
Considerations for this significant and unavoidable impact.
Proposed Zoning Regulations Update Analysis and Conclusions
The LUCE EIR states that one segment north of Madonna Road (post mile 28.088) is projected to experience unstable flow
conditions (LOS F) in northbound direction during the AM peak hour, and all other segments are projected to operate at
LOS D or better during the AM peak hour in 2035. During the PM peak hour in the southbound direction, all US 101
segments (4.074 centerline miles of freeway) are projected to experience unstable flow conditions (LOS F). All segments
in the northbound direction are projected to operate at LOS D. Despite compliance with LUCE policies and programs,
freeway impacts would not be reduced to less than significant levels. Therefore, this impact is considered to be significant
and unavoidable, consistent with the determination in the LUCE EIR.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Implementation of the
proposed amendments to the Zoning Regulations to allow a minimum number of dwelling units on multi-family zoned lots
would result in an average increase in density of 0.53, 0.84, and 1.22 density units on R-2, R-3, and R-4 lots, respectively.
This may reasonably translate into: one additional bedroom on R-2 lots; one additional bedroom on R-3 lots, and two
additional bedrooms on R-4 lots. Implementation of the proposed amendment to the Zoning Regulations to allow a
minimum number of dwelling units on office zoned lots would result in an average increase in density of 0.49 density unit.
This may reasonably translate into one additional bedroom on O lots. The proposed changes to allowable density in the R-3
zone and proposed minimum dwelling unit standards in the R-2, R-3, R-4, and O zones would be consistent with the
analysis and conclusions of the LUCE EIR, because: these changes are consistent with adopted LUCE maximum dwelling
density for the Medium-High Density Residential land use designation (20 units per acre, as shown in LUE Table 4.
Residential Population Assumptions), the changes would be consistent with the intention of the Medium, Medium-High
and High Density Residential and Office land use designations to provide multi-family and other residential opportunities,
development of housing projects pursuant to the proposed regulations would generate additional multi-modal traffic and
result in similar impacts and conclusions as disclosed in the LUCE EIR, future development would be subject to
performance and design standards established for these residential and office zones, future development would be subject
to consistency with the Circulation Element, and potential build-out pursuant to the proposed Project remains subject to the
one percent growth limitation.
As development under the LUCE and Zoning Regulations Update is proposed, the City will be required to ensure
consistency with the General Plan. While the Zoning Regulations Update does not include any regulations that are
inconsistent with the Circulation Element, the anticipated traffic that would be generated upon build-out of the City
pursuant to the LUCE and implementation of existing and proposed Zoning Regulations would result in the degradation of
LOS, as identified in LUCE EIR Section 4.15 Transportation and Circulation. Compliance with Circulation Element
policies and programs that contribute to reducing volumes along roadways would partially mitigate this significant impact.
In addition, pursuant to CEQA, future new land uses that occur pursuant to the proposed Project would be subject to their
own environmental review on a project-by-project basis to assess traffic impacts; however, consistent with the LUCE EIR,

the impact would remain significant and unavoidable. Therefore, the proposed Project would not result in a significant
transportation impact not examined or adequately addressed in the LUCE EIR.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Zoning Regulations Update would not allow new development in areas where such development is prohibited
under the LUCE. Therefore, the proposed Zoning Regulations Update would not result in a significant transportation and
circulation impact not examined or adequately addressed in the LUCE EIR Section 4.15 Transportation and Circulation.
c) Implementation of the General Plan and proposed Zoning Regulations Update would not result in any changes in air traffic
patterns. Potential impacts due to increased traffic associated with the San Luis Obispo County Airport are discussed below
(refer to the discussion under d).
d) LUCE EIR Conclusion
Roadways improved consistent with the Circulation Element would be designed in compliance with City Engineering
Standards; however, implementation of future development pursuant to the LUCE has the potential to increase traffic
volumes and speeds in neighborhoods. Compliance with Circulation Element policies including the following would
address neighborhood traffic: 8.1.1 Through Traffic; 8.1.2 Residential Streets; 8.1.3 Neighborhood Traffic Speeds; 8.1.4
Neighborhood Traffic Management; 8.1.5 Neighborhood Traffic Management Guidelines; 8.1.6 Non‐Infill Development;
and 8.1.7 New Project Evaluation. The LUCE EIR concluded that “development under the LUCE Update may increase
traffic volumes or traffic speed in designated neighborhood traffic management areas. Impact is considered to be Class III,
less than significant” (LUCE EIR, Section 4.16 Transportation and Circulation, Impact CIR-4).
Implementation of the LUCE may encourage increased truck traffic on non‐designated truck routes. The Circulation
Element includes the following policy to address increased truck traffic: 10.1.1 Truck Routes. The LUCE EIR concluded
that “development under the LUCE Update may encourage increased heavy vehicle traffic on non‐designated truck routes.
Impact is considered to be Class III, less than significant” (LUCE EIR, Section 4.16 Transportation and Circulation, Impact
CIR‐5).
The LUCE EIR states that implementation of the LUCE may lead to changes in traffic volumes of traffic patterns that result
in deteriorated safety conditions. Future development will comply with Circulation Element policies including: 11.1.1
Interstate Air Service; 11.1.2 County Aircraft Operations; and 11.1.3 Public Transit Service. The LUCE EIR concludes that
“development under the LUCE Update will cause increased activity at San Luis Obispo County Regional Airport that may
lead to changes in traffic volumes or traffic patterns that result in deteriorated safety conditions. Impact is considered to be
Class III, less than significant” (LUCE EIR Section 4.16 Transportation and Circulation, Impact CIR‐6).
Proposed Zoning Regulations Update Analysis and Conclusions
Future land uses that occur pursuant to the proposed Zoning Regulations Update would be required to conform to all
applicable regulations performance standards and design standards that address safety, including those of the Zoning
Regulations, as updated, the Circulation Element, and City Engineering Standards. Future development proposals would be
reviewed on a case-by-case basis as they arise to determine if project layouts, driveway locations, land use types, or actual
intensities would result in hazardous conditions. Therefore, the proposed Zoning Regulations Update would not
substantially increase hazards due to a design feature. Impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. The
proposed Project would make revisions, additions, corrections and clarifications to various sections of the Zoning
Regulations to ensure consistency and successful implementation of the LUCE. The proposed Project would not allow new
development in areas where such development is prohibited under the LUCE. Therefore, there would be no new impacts
that have not been previously examined or adequately addressed in the LUCE EIR Section 4.16 Transportation and
Circulation.

e) Emergency access requirements are established in the Fire Code and are reviewed and approved by the City Fire Marshal.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable regulations that address emergency
access, including Fire Code requirements. Future development proposals would be reviewed on a case-by-case basis by the
City Fire Department as they arise to determine if adequate emergency access is provided. Therefore, the proposed Zoning
Regulations Update would not result in inadequate emergency access. Impacts would be less than significant. Refer to
Initial Study Section 8 Hazards and Hazardous Materials for additional discussion regarding emergency access.
f) The Circulation Element provides policies that encourage the use of active transportation modes within the City, including:
4.1.1 Bicycle Use; 4.1.2 Campus and School Site Trips; 4.1.3 Continuous Network; 4.1.4 New Development; 4.1.5
Bikeway Design and Maintenance; 4.1.6 Bikeway Development with Road Improvements; 4.1.7 Education and Safety;
4.1.8 Bicycle Transportation Coordinator; 4.1.9 Traffic Law Compliance; 4.1.10 Right‐of‐way Acquisition; 4.1.11 Bicycle

Development 5.1.4 Pedestrian Access; 5.1.5 Pedestrian Crossings; 5.1.6 Downtown Commercial Core; and 5.1.7
Sidewalks.
LUCE EIR Conclusion
The LUCE EIR concluded that “development and street network changes and adoption of the policies and programs under
the LUCE Update would not conflict with adopted policies that are supportive of increased active transportation. Impact is
considered to be Class III, less than significant” (LUCE EIR Section 4.15, Transportation and Circulation Impact CIR-7).
The LUCE EIR also concluded that “development and adoption of the policies and programs under the LUCE Update
would not conflict with adopted policies that are supportive of increased transit ridership and provision of services. Impact
is considered to be Class III, less than significant” (LUCE EIR Section 4.15, Transportation and Circulation Impact CIR-8).
Proposed Zoning Regulations Update Analysis and Conclusions
Adoption of the Zoning Regulations Update will not impose new barriers on bicycle and pedestrian traffic or use of transit
within the City, nor will in conflict with existing policies that are supportive of these alternative modes of transportation as
identified in the Circulation Element. The proposed Zoning Regulations Update implements the goals and policies of the
LUCE, including updating parking requirements to “encourage bicycling, transit use, walking, carpooling, and other modes
of transportation (other than motor vehicle) that can move the City toward achieving modal split goals in the General Plan
Circulation Element” (proposed Zoning Regulations, Article 3). The proposed Project clarifies standards addressing short-
term and long-term bicycle parking and storage, simplifies parking requirements consistent with trip demands (revised
Table 9), and requires showers, lockers, and changing rooms in non-residential projects over 20,000 square feet. Future
land uses that occur pursuant to the proposed Zoning Regulations Update would be required to conform to all applicable
regulations performance standards and design standards, including those of the Zoning Regulations, as updated, the
Circulation Element, and City Engineering Standards. Therefore, impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would not allow new development in areas where such development
is prohibited under the LUCE. Pursuant to CEQA, future new land uses that occur pursuant to the proposed Zoning
Regulations Update would be subject to their own environmental review on a project-by-project basis to assess consistency
with the Circulation Element. Therefore, the proposed Zoning Regulations Update would not result in a significant impact
not examined or adequately addressed in LUCE EIR Section 4.15 Transportation and Circulation.
17. TRIBAL CULTURAL RESOURCES. Would the project cause a substantial adverse change in the significance of a
tribal cultural resource, defined in Public Resources Code Section 21074 as either a site, feature, place, cultural
landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with
cultural value to a California Native American tribe, and that is:

Evaluation
On April 26, 2018, local Native American tribal groups were formally noticed that an Initial Study of Environmental Impact
was being completed for the proposed Zoning Regulations Update and invited to provide consultation on the proposed project.
No tribal representatives requested a formal consultation; however, two representatives discussed the proposed Zoning
Regulations with City Staff and one requested additional policy language to be included in the Zoning Regulation Update. No
specific tribal cultural resources were identified by the tribal representatives.
a) The City contains multiple resources that are listed or eligible for listing in the California Register of Historical Resources,
and/or in the City’s list of historical resources. Development facilitated by the LUCE and Zoning Regulations Update could
adversely affect identified and previously unidentified historical and archaeological resources. However, adherence to
existing Federal, State and City policies and programs, will address these impacts by requiring the study of site-specific
resources, identification of significant resources present within a given project site, requirements to avoid significant
resources and requirements to mitigate any impacts to these resources through project design, tribal consultation,
monitoring and Native American consultation. As such, impacts are considered less than significant.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land use that
occur pursuant to the proposed Project would be required to conform to federal, State, and local guidelines and
requirements that address historical, archaeological, and tribal cultural resources. Pursuant to CEQA, future new land uses
that occur pursuant to the proposed Zoning Regulations Update would be subject to their own environmental review and
associated tribal consultations on a project-by-project basis to assess potential impacts. Therefore, impacts would be less
than significant.
Conclusion. The proposed Project would make revisions, additions, corrections and clarifications to various sections of the
Zoning Regulations to ensure consistency and successful implementation of the LUCE. The proposed Zoning Regulations
Update would not allow new development in areas where such development is prohibited under the LUCE. Future
development that occurs pursuant to the proposed Project would be required to conform to all applicable regulations of the
Zoning Regulations, as updated, the LUCE and COSE, the Historic Preservation Ordinance, Historic Preservation Program
Guidelines, and Archaeological Resource Preservation Program Guidelines, which address historical and archaeological
resources. In addition, pursuant to State CEQA Guidelines Section 21080.3.1, the City will continue to conduct tribal
consultations on all projects are required by CEQA. Therefore, there would be no new impacts that have not been
previously examined or adequately addressed in LUCE EIR Section 4.5, Cultural Resources.
b) Based on the unique nature of the proposed Project, which does not by itself propose or authorize any development,
consultation with tribal representatives resulted in the following recommendation by a tribal representative: Request to
modify Zoning Regulations language specific to the S zone as follows (additional language is underlined): The S zone has
two purposes: A. In combination with any zone, to require approval of an administrative use permit before any use may be
established. The use permit requirement is intended to assure compatibility of the use with its surroundings or
conformance with the general plan, or to determine if a proposed development solves problems such as noise exposure,
flood hazard, airport hazard, or slope instability which are particularly severe on a given site. Such development review
may also be used to protect areas of scenic, or ecological sensitivity, historic resources, indigenous cultural resources,

wildlife habitat, or wildland fire hazard”.
The tribal representative also requested expanded creek setbacks (from 20 to 50 feet) throughout the City, as these places
can contain cultural resources, and the change would help protect culturally important and sensitive places well before any
construction activity has begun. The City does not recommend expanding the creek setback to 50 feet in all locations of
the City, as this may present an infeasible limitation on development within the urban core of the City. In addition, the
City’s Archaeological Resource Preservation Program Guidelines defines areas within 200 feet of identified creeks as
sensitive, and thus requires a Phase I Archaeological Investigation including a records search and field survey. Therefore, it
is City Staff’s recommendation to retain the 20-foot setback where indicated in the Zoning Regulations and maintain
compliance with the City’s adopted Archaeological Resource Preservation Program Guidelines.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land use that
occur pursuant to the proposed Project would be required to conform to federal, State, and local guidelines and
requirements that address tribal cultural resources. Pursuant to CEQA, future new land uses that occur pursuant to the
proposed Zoning Regulations Update would be subject to their own environmental review and associated tribal
consultations on a project-by-project basis to assess potential impacts. In addition, the language identified by the tribal
representative has been incorporated into the proposed Zoning Regulations Update. Therefore, impacts would be less than
significant.
Conclusion. The proposed Project would make revisions, additions, corrections and clarifications to various sections of the
Zoning Regulations to ensure consistency and successful implementation of the LUCE. The proposed Zoning Regulations
Update would not allow new development in areas where such development is prohibited under the LUCE. The language
identified by the tribal representative regarding the S Overlay has been incorporated into the proposed Zoning Regulations
Update. In addition, future development would be subject to tribal consultation, when required by CEQA. Therefore, no
significant impacts to tribal cultural resources would occur as a result of the proposed Project.

Water. As discussed in the City’s LUCE Update EIR, the City of San Luis Obispo Utilities Department provides potable and
recycled water to the community and is responsible for water supply, treatment, distribution, and resource planning. The City is
the sole water provider within the city limits and most of the City’s water is supplied from multiple surface water sources.
However, the City also uses groundwater to supplement surface water supplies and recycled water is used to supplement
irrigation demand. With the update of the City’s Water and Wastewater Element in 2018, the City Council reaffirmed the policy
for a multi‐source water supply. Consistent with the multi‐source water supply concept, the City obtains water from five
sources:
Salinas Reservoir (Santa Margarita Lake) and Whale Rock Reservoir: Combined Safe Annual Yield 4,910 AF/year
Nacimiento Reservoir: 5,482 AF/year dependable yield/ contractual limit
Recycled water from the City’s Water Resource Recovery Facility (WRRF): 238 AF/year
Wastewater: The wastewater system for the City includes facilities for wastewater collection and treatment. The City’s
collection system serves residential, commercial, and industrial customers. Sewer service is provided only to properties within
the city limits, with the exception of a few residential properties located just outside of the city limits, Cal Poly San Luis
Obispo, and the County of San Luis Obispo Airport. There are approximately 12,000 service connections.
The City’s Water Resource Recovery Facility (WRRF) processes wastewater in accordance with the standards set by the State’s
RWQCB. The WRRF removes solids, reduces the amount of nutrients, and eliminates bacteria in the treated wastewater, which
is then discharged to San Luis Obispo Creek. The WRRF is designed for an average dry weather flow capacity of 5.4 million
gallons per day (MGD) and a peak wet weather flow capacity of 19 MGD. In 2017, annual average flows to the WRRF were
approximately 3.30 MGD.
Solid Waste: The City’s Utilities Department is responsible for administering an exclusive franchise agreement with San Luis
Garbage Company to collect and dispose solid waste generated by residential, commercial, and industrial customers in San Luis
Obispo. This agreement also includes curbside recycling, and green waste service. There are three solid waste disposal facilities
within San Luis Obispo County. Most solid waste collected in the city is disposed of at the Cold Canyon Landfill. Cold Canyon
Landfill is currently (2016) permitted to receive up to 1,650 tons of solid waste per day, with an estimated remaining capacity
of 14,500,000 cubic yards (60.1 percent remaining capacity). In 2015, the Cold Canyon Landfill operator estimated the landfill
is expected to reach capacity in 2040.
a), e) LUCE EIR Conclusion
Potential future wastewater flows resulting from land use changes implemented under the LUE are shown on LUCE EIR
Section 4.16 Utilities and Service Systems, Table 4.16‐7 Proposed Land Use Element Development Wastewater
Generation. Buildout of the LUE would result in wastewater flows of approximately 0.97 MGD, which when added to
existing wastewater flows would result in LUE buildout wastewater flows of approximately 5.36 MGD. Future wastewater
flows that could result from the buildout of the proposed LUE would exceed the existing WRRF treatment capacity by
approximately 0.26 MGD.
The LUCE EIR concluded that “new development that could occur as a result of the LUCE Update would generate
wastewater flows that exceed the existing capacity of the City’s Water Resource Recovery Facility. This is a Class III, less
than significant impact” (LUCE EIR, Section 4.16 Utilities and Service Systems, Impact USS-2).
Proposed Zoning Regulations Update Analysis and Conclusions
In 2018, the City approved a proposed upgrade to the WRRF, including certification of an EIR for the Water Resource

Recovery Facility Project. The WRRF project entails upgrading the City’s wastewater treatment facility to comply with
updated discharge requirements outlined in the National Pollutant Discharge Elimination System (NPDES) permit adopted
by the Regional Water Quality Control Board (RWQCB) and State Water Resources Control Board (SWRCB) in
September 2014. The NPDES permit went into effect December 1, 2014, and compliance is required by November 30,
2019. At the same time, the WRRF would be upgraded to provide a nominal increase in average dry weather flow (ADWF)
capacity to serve the needs of the City, as projected in the LUE.
In addition, the 2018 Water and Wastewater Element includes extensive policies and programs intended to minimize and
mitigate for potential impacts related to wastewater collection and treatment for buildout of the LUE. In compliance with
the 2018 Water and Wastewater Element, development identified by the LUE could not occur unless it was demonstrated
that adequate treatment capacity at the WRRF existed prior to approval of future development projects. Therefore,
implementation of the future development pursuant to the LUE would not result in new development and associated
increases in wastewater flows that would exceed the capacity of the WRRF. Future development projects pursuant to the
proposed Zoning Regulations Update would be required to demonstrate that adequate treatment capacity exists prior to the
approval of those projects. Implementation of the approved WRRF expansion and existing Water and Wastewater Element
policies would reduce potential wastewater treatment impacts resulting from implementation of the LUCE pursuant to the
proposed Zoning Regulations Update to a less than significant level.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Implementation of the
proposed amendments to the Zoning Regulations to allow a minimum number of dwelling units on multi-family zoned lots
would result in an average increase in density of 0.53, 0.84, and 1.22 density units on R-2, R-3, and R-4 lots, respectively.
This may reasonably translate into: one additional bedroom on R-2 lots; one additional bedroom on R-3 lots, and two
additional bedrooms on R-4 lots. Implementation of the proposed amendment to the Zoning Regulations to allow a
minimum number of dwelling units on office zoned lots would result in an average increase in density of 0.49 density unit.
This may reasonably translate into one additional bedroom on O lots. The proposed changes to allowable density in the R-3
zone and proposed minimum dwelling unit standards in the R-2, R-3, R-4, and O zones would be consistent with the
analysis and conclusions of the LUCE EIR, because: these changes are consistent with adopted LUCE maximum dwelling
density for the Medium-High Density Residential land use designation (20 units per acre, as shown in LUE Table 4.
Residential Population Assumptions), the changes would be consistent with the intention of the Medium, Medium-High
and High Density Residential, and Office land use designations to provide multi-family and other residential opportunities,
development of housing projects pursuant to the proposed regulations would result in similar impacts and conclusions as
disclosed in the LUCE EIR, future development would be subject to performance and design standards established for
these residential and office zones, and potential build-out pursuant to the proposed Project remains subject to the one
percent growth limitation.
Future land uses that occur pursuant to the proposed Project would be required to conform to all applicable regulations that
address wastewater collection and treatment, including those set forth in the City’s General Plan and state and federal water
quality regulations. Additionally, future development proposals would be reviewed on a case-by-case basis as they arise to
confirm available capacity at the WRRF, consistent with the General Plan. Therefore, the proposed Zoning Regulations
Update would not require or result in new wastewater facilities, and impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Zoning Regulations Update would not allow new development in areas where such development is prohibited
under the LUCE. Therefore, the proposed Zoning Regulations Update would not result in a significant wastewater impact
not examined or adequately addressed in the LUCE EIR (LUCE Section 4.16 Utilities and Service Systems).
b) LUCE EIR Conclusion
As documented in LUCE EIR Section 4.16 Utilities and Service Systems, parts of the city’s water distribution and
wastewater collection systems are approaching or are past their estimated lifespan. In addition, new development proposed
by the LUE could require the installation of new or upgraded water transmission and distribution mains, and the installation

of new water tanks. The City’s Water Master Plan identifies needed improvements to the water distribution system,
including water tanks that are undersized. Wastewater collection to serve new development may also require the
installation of new or upgraded gravity sewer lines, force mains and pump stations. The Infrastructure Renewal Strategy
identifies capacity issues for the wastewater collection system and a prioritized list of replacements. Environmental impacts
that may result from the construction of new or upgraded infrastructure pipelines, water tanks, lift stations and other
facilities generally include the potential for short‐term impacts such as construction‐related increases in noise and air
emissions, temporary roadway lane closures and other circulation‐related impacts, water quality impacts from increased
erosion or an accidental release of construction materials. Impacts to sensitive biologic or cultural resources may also result
if resources are present within or adjacent to proposed construction corridors. The construction of above‐ground facilities,
such as water tanks, may have the potential to result in long‐term aesthetic impacts.
Short‐term construction impacts that may be result from infrastructure improvement projects are usually minimized by
standard construction site and operation measures such as: designing projects to avoid or minimize construction activities
in or adjacent to sensitive areas; implementing appropriate resource protection/restoration measures; implementing
standard safety precautions; conducting construction activities in a manner that minimizes equipment use and other
construction activities within and adjacent to construction corridors; and compliance with applicable regulatory
requirements and City policies. For example, LUE Policy 12.9 Environmental Review requires project-specific reviews to
identify potential on‐ and off‐site environmental impacts that may result from future infrastructure improvements.
The LUCE EIR concluded that “new development that could be facilitated by the LUCE Update would require the
construction of new water and wastewater infrastructure or the replacement of existing infrastructure. The construction or
replacement of infrastructure has the potential to result in significant environmental effects. This is a Class III, less than
significant impact” (LUCE EIR Section 4.16 Utilities and Service Systems, Impact USS-3).
Proposed Zoning Regulations Update Analysis and Conclusions
With adherence to existing policy and development review requirements, potential infrastructure construction impacts
associated with the proposed Zoning Regulations Update would be less than significant. Implementation of the LUCE
pursuant to the proposed Zoning Regulations would reduce potential infrastructure construction impacts to a less than
significant level. Subsequent development projects would be required to demonstrate compliance with the applicable
policies and regulatory requirements, and if required, may be subject to the implementation of additional mitigation
measures.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Implementation of the
proposed amendments to the Zoning Regulations to allow a minimum number of dwelling units on multi-family zoned lots
would result in an average increase in density of 0.53, 0.84, and 1.22 density units on R-2, R-3, and R-4 lots, respectively.
This may reasonably translate into: one additional bedroom on R-2 lots; one additional bedroom on R-3 lots, and two
additional bedrooms on R-4 lots. Implementation of the proposed amendment to the Zoning Regulations to allow a
minimum number of dwelling units on office zoned lots would result in an average increase in density of 0.49 density unit.
This may reasonably translate into one additional bedroom on O lots. The proposed changes to allowable density in the R-3

Future land uses that occur pursuant to the proposed Project would be required to conform to all applicable regulations that
address water and wastewater infrastructure. Additionally, future development proposals would be reviewed on a case-by-
case basis as they arise to confirm sufficient infrastructure. Therefore, the proposed Zoning Regulations Update would not
require or result in new or expanded water or wastewater infrastructure, and impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Zoning Regulations Update would not allow new development in areas where such development is prohibited
under the LUCE. Therefore, the proposed Zoning Regulations Update would not result in a significant infrastructure
impact not examined or adequately addressed in LUCE EIR Section 4.16 Utilities and Service Systems.
c) LUCE EIR Conclusion and Proposed Zoning Regulations Update Analysis and Conclusion
As documented in the LUCE EIR, development pursuant to the LUCE could cause an increase in the amount of impervious
surfaces within the city which may increase the volume of surface runoff into City stormwater systems. Future
development and redevelopment projects within the City are required to comply with the Central Coast Regional Water
Quality Control Board Post Construction Requirements. As discussed in more detail in Initial Study Section 9 Hydrology
and Water Quality, based on compliance with the terms of the City’s SWMP, impacts would be less than significant.
Similar to the construction of water and wastewater infrastructure (see discussion in Section 4.16 Utilities and Service
Systems, section b), potential short-term construction impacts can be minimized to less than significant.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable regulations that address drainage and
stormwater infrastructure. Additionally, future development proposals would be reviewed on a case-by-case basis as they
arise to confirm sufficient infrastructure. Therefore, the proposed Zoning Regulations Update would not require or result in
new or expanded drainage or stormwater infrastructure, and impacts would be less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Zoning Regulations Update would not allow new development in areas where such development is prohibited
under the LUCE. Therefore, the proposed Zoning Regulations Update would not result in a significant infrastructure
impact not examined or adequately addressed in LUCE EIR Section 4.16 Utilities and Service Systems and LUCE EIR
Section 4.9 Hydrology and Water Quality.
d) LUCE EIR Conclusion
The LUCE EIR states that buildout of the proposed LUE could result in approximately 4,904 additional residential units in
the City, potentially resulting in approximately 25,601 dwelling units located in the City by 2035. Using a dwelling unit
occupancy rate of 2.29 persons per dwelling unit, buildout of the LUE could support a General Plan buildout population of
approximately 58,626. As documented in the LUCE EIR, the primary water supply required for estimated buildout demand
resulting from the LUE would be 7,815 AF/year (LUCE EIR Section 4.16 Utilities and Service Systems). LUCE EIR
Section 4.16 Utilities and Service Systems, Table 4.16‐5 Proposed Land Use Element Buildout Water Supply summarizes
water supply and demand conditions associated with the buildout of the LUCE. Future water supply estimates have been
updated based on the recent adoption of the 2018 Water and Wastewater General Plan Element. As noted above, the City
obtains water from five sources, totaling 10,630 AF/year, which is greater than the identified demand for build-out. The
LUCE EIR concluded that “new development that could occur as a result of the proposed LUCE Update would increase
existing water demand. This is a Class III, less than significant impact” (LUCE EIR, Section 4.16 Utilities and Service
Systems, Impact USS-1).
Proposed Zoning Regulations Update Analysis and Conclusions
Adherence to the existing City’s Water and Wastewater Element and the 2010 Urban Water Management Plan will ensure

that impacts related to water demand for new development construction and operated pursuant to the proposed Zoning
Regulations Update would remain less than significant. Individual development will be required to undergo separate
environmental review, which may include preparation of a Water Supply Assessment and other impact analysis, which may
result in requirements for project specific mitigation.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Implementation of the
proposed amendments to the Zoning Regulations to allow a minimum number of dwelling units on multi-family zoned lots
would result in an average increase in density of 0.53, 0.84, and 1.22 density units on R-2, R-3, and R-4 lots, respectively.
This may reasonably translate into: one additional bedroom on R-2 lots; one additional bedroom on R-3 lots, and two
additional bedrooms on R-4 lots. Implementation of the proposed amendment to the Zoning Regulations to allow a
minimum number of dwelling units on office zoned lots would result in an average increase in density of 0.49 density unit.
This may reasonably translate into one additional bedroom on O lots. The proposed changes to allowable density in the R-3
zone and proposed minimum dwelling unit standards in the R-2, R-3, R-4, and O zones would be consistent with the
analysis and conclusions of the LUCE EIR, because: these changes are consistent with adopted LUCE maximum dwelling
density for the Medium-High Density Residential land use designation (20 units per acre, as shown in LUE Table 4.
Residential Population Assumptions), the changes would be consistent with the intention of the Medium, Medium-High
and High Density Residential, and Office land use designations to provide multi-family and other residential opportunities,
development of housing projects pursuant to the proposed regulations would result in similar impacts and conclusions as
disclosed in the LUCE EIR, future development would be subject to performance, design, landscaping, and water
conservation standards established for these residential and office zones, and potential build-out pursuant to the proposed
Project remains subject to the one percent growth limitation.
Future land uses that occur pursuant to the proposed Project would be required to conform to all applicable regulations that
address water use and water conservation, including those set forth in the City’s General Plan, CBC, and CALGreen, and
drought-related water conservation laws. Additionally, future development proposals would be reviewed on a case-by-case
basis as they arise to confirm available water supply and sufficient infrastructure. Therefore, the proposed Zoning
Regulations Update would not require or result in new or expanded water entitlements, and impacts would be less than
significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Zoning Regulations Update would not allow new development in areas where such development is prohibited
under the LUCE. Therefore, the proposed Zoning Regulations Update would not result in a significant water supply impact
not examined or adequately addressed in LUCE Section 4.16 Utilities and Service Systems.
f), g) The Integrated Waste Management Act of 1989 (AB 939) requires each city and county in California to reduce the flow of
materials to landfills by 50% (from 1989 levels) by 2000. The proposed project is required to reduce the waste stream
generated by development consistent with the City’s Conservation and Open Space Element policies to coordinate waste
reduction and recycling efforts (COSE 5.5.3), and Development Standards for Solid Waste Services (available at
http://www.slocity.org/home/showdocument?id=4384). A solid waste reduction plan for recycling discarded construction
materials is a submittal requirement with the building permit application.
LUCE EIR Conclusion
The LUCE EIR determined that potentially significant solid waste disposal impacts that could result from inadequate
disposal capacity would be minimized by LUE Policy 1.13.10 Solid Waste Capacity, which requires that adequate solid
waste disposal capacity be available to serve new development. The policy states: “In addition to other requirements for
adequate resources and services prior to development, the City must shall determine require that adequate solid waste
disposal capacity will be available exists before granting any discretionary land use approval which would increase solid
waste generation. San Luis Obispo City and County are focusing on waste diversion and recycling efforts to minimize
future waste disposal impacts. For example, new development projects are required to minimize short‐term waste disposal

impacts by recycling construction and demolition waste. Long‐term waste disposal impacts are minimized by including
facilities for the collection and storage of recyclables in new development projects. These efforts will enhance the ability of
the City to achieve a 75 percent diversion rate by the year 2020 and to ultimately be as close to zero waste as possible”.
The LUCE EIR concludes that “new development that could be facilitated by the LUCE Update would increase the
demand for solid waste disposal at county landfills. Potential new development would also comply with applicable
regulations related to the management of solid waste. As such, solid waste disposal impacts of the LUCE Update are Class
III, less than significant impact” (LUCE EIR Section 4.16, Utilities and Service Systems Impact USS-4).
Proposed Zoning Regulations Update Analysis and Conclusions
With adherence to the policy requirements identified above, potential solid waste disposal impacts would be less than
significant and new development facilitated by the proposed Zoning Regulations Update would not interfere with the
City’s ability to comply with regulations related to solid waste management or increased solid waste diversion rates.
Therefore, compliance with the LUE would reduce potential solid waste disposal and diversion impacts to a less than
significant level. Subsequent development projects would be required to demonstrate compliance with the applicable
policies and regulatory requirements, and if required, may be subject to the implementation of additional mitigation
measures.
The proposed Zoning Regulations Update, by itself, does not propose or authorize any development. Future land uses that
occur pursuant to the proposed Project would be required to conform to all applicable regulations that address waste
storage and disposal, including those set forth in the City’s General Plan. Therefore, the development that would occur
under the proposed Zoning Regulations Update would be served by landfills with adequate capacity, and impacts would be
less than significant.
Conclusion. The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to
various sections of the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The
proposed Zoning Regulations Update would not allow new development in areas where such development is prohibited
under the LUCE. Therefore, the proposed Zoning Regulations Update would not result in a significant waste impact not
examined or adequately addressed in LUCE EIR Section 4.16 Utilities and Service Systems.
19. MANDATORY FINDINGS OF SIGNIFICANCE.
a) Does the project have the potential to degrade the quality of the
environment, substantially reduce the habitat of a fish or
wildlife species, cause a fish or wildlife population to drop
below self-sustaining levels, threaten to eliminate a plant or
animal community, reduce the number or restrict the range of a
rare or endangered plant or animal or eliminate important
examples of the major periods of California history or
prehistory?
X
The proposed Zoning Regulations Update would make revisions, additions, corrections and clarifications to various sections of
the Zoning Regulations to ensure consistency and successful implementation of the LUCE. The proposed Zoning Regulations
Update does not authorize any development. Therefore, its adoption would not significantly degrade the quality of the
environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-
sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or
endangered plant or animal, or eliminate important examples of the major periods of California history or prehistory. Therefore,
as discussed in Section 4 (Biological Resources) of this Initial Study, no new significant impacts beyond what is identified in
the LUCE EIR would occur.
b) Does the project have impacts that are individually limited, but
cumulatively considerable? ("Cumulatively considerable"

means that the incremental effects of a project are considerable
when viewed in connection with the effects of the past
projects, the effects of other current projects, and the effects of
probable future projects)?
The proposed project involves the adoption of the City’s Zoning Regulations Update, which guides future development. No
specific development projects would occur as a result of the proposed Zoning Regulations Update and therefore, the project, in
itself, would not result in cumulative impacts. Furthermore, cumulative impacts associated with future development have been
evaluated at a program level in the LUCE EIR. Since the proposed Zoning Regulations Update would not allow new
development in areas where such development is prohibited under the LUCE, adopting the proposed Zoning Regulations
Update would not create new cumulative impacts or increase the significance of cumulative impacts identified in the LUCE
EIR.
c) Does the project have environmental effects which will cause
substantial adverse effects on human beings, either directly or
indirectly?
X
As identified throughout the analysis herein, the proposed Zoning Regulations Update would not have an environmental effect
that would cause substantial adverse effects on human beings either directly or indirectly. Impacts would be less than
significant.

use shall not be allowed, except as provided below.
B. Director’s Determination. Based on the authority granted in Section 17.04.020 (Procedures for Interpretation),
the Director may determine that a land use that is not listed in Chapter 17.10 (Use Regulations) may be allowed.
In making this determination, the Director shall first make all of the following findings:
1. The characteristics of, and activities associated with, the use are equivalent to those of one or more of the
uses listed in the zone as allowable, and will not involve a greater level of activity, population density, intensity,
traffic generation, parking, dust, odor, noise, emissions, or similar impacts than the uses listed in the zone;
2. The use will meet the purpose/intent of the zone that is applied to the location of the use; and
3. The use will be consistent with the goals, objectives, and policies of the General Plan and/or any applicable
specific plan or planned development.
C. Applicable Standards and Permit Requirements. When the Director determines that an unlisted land use is
equivalent to a listed use, the unlisted use will be treated in the same manner as the listed use in determining
where the use is allowed, what permits are required, and what other standards and requirements of the Zoning
Regulations apply.

All areas within the City shall be designated within a zone. The boundaries, designations, map symbols and locations
of the zones established by the Zoning Regulations shall be shown upon the map(s) entitled "City of San Luis Obispo
Zoning Map" and referred to in the Zoning Regulations as the Zoning Map. The official Zoning Map, which shall depict
all duly adopted zones, is as much a part of these regulations as if it were fully contained in this document. The official
Zoning Map shall be maintained by and in the Community Development Department, and for convenience in more
easily identifying zone boundaries may be divided into parts.
17.06.040 – Uncertainty of Boundaries
A.General. Boundaries between zones generally follow lot lines or their extensions, physical features, or contour
lines, as noted on the official Zoning Map. Boundaries adjoining streets shall be assumed to follow the centerlines
of streets if such location becomes an issue in the use of private property, as when a street is abandoned. Zones
which meet a street centerline shall not be considered “adjacent.”
B.Split Zoning. A split-zoned parcel is a parcel to which two or more base zones apply (which does not include
overlay zones). All applicable Zoning Regulations for each particular zone shall be applied separately for each
portion of a parcel that is split-zoned. This includes the front, rear and side setback regulations, regardless of the
standard setback definition provided in Chapter 17.158 (General Definitions), as well as any applicable lot
coverage regulations.
C.Determination. The location of boundaries which are not readily determined by inspection of the official Zoning
Map shall be determined by the Director.

A. General Application. The C/OS zone generally will be applied to areas which are most suitable for open space
uses because of topography, geology, vegetation, soils, wildlife habitat, scenic prominence, agricultural value, or
flood hazards. Land and water areas in the C/OS zone remain in a predominantly natural or undeveloped state
generally free of structures.
B. Natural Hazards. The C/OS zone is intended to prevent exposure of urban development to unacceptable risks
posed by natural hazards and to protect natural resources from disruptive alterations. To these ends, it is further
intended to prevent the subdivision of such lands.
C. Natural and Historic Resources. The C/OS zone provides for the protection and preservation of the community’s
natural and historic resources, defines the urban boundary, and provides visual and physical relief from urban
development.
17.14.020 – Development Standards
The general property development standards for the C/OS zone shall be as set forth in Table 2-3: C/OS Zone

The C-D zone is intended to accommodate a wide range of retail sales, service, and entertainment uses that respond
to community-wide and regional market demands, and to provide opportunities for a variety of housing types, including
affordable workforce housing. The C-D zone applies to the City’s pedestrian-oriented central business district, where
the historical pattern of development creates limitations on building form and the ability for individual businesses to
provide onsite parking. Ground-floor, street-fronting uses generally will be limited to those that attract frequent pedestrian
traffic. The C-D zone is intended to maintain, enhance, and extend the desirable characteristics of the downtown, and
to accommodate carefully integrated new development.
17.32.020 – Development Standards
The general property development standards for the C-D zone shall be as set forth in Table 2-18: C-D Zone

17.32.030 – Additional Regulations
A. Maximum Retail Sales Building Size in the C-D Zone.
1. No retail sales establishment (commercial building) shall exceed 60,000 square feet of gross floor area, unless
excepted by subsection (C.2) of this Section or for nonconforming structures per Chapter 17.92
(Nonconforming Structures).
2. An applicant may request a retail sales building larger than 60,000 square feet, but in no case larger than
140,000 square feet through the Conditional Use Permit process. In granting a request for a retail
establishment of up 140,000 square feet of gross floor area, the Planning Commission shall make all of the
following findings:
a. The proposed use will serve the community, in whole or in significant part, and the nature of the use
requires a larger size in order to function;
b. The building in which the use is to be located is designed in discrete elements that respect the scale of
development in the surrounding area; and
c. The new building is designed in compliance with the City’s Design Guidelines for large-scale retail projects.
B. Limitations on New Driveways. Although residential uses are encouraged in the C-D zone, it is not the intent of
the City to ensure that parking is provided onsite for residential uses. Therefore, there is no guarantee of parking
availability, either onsite or off site, for downtown residential projects. Onsite parking may be considered
inappropriate at certain downtown locations where the pedestrian experience would be harmed by vehicle ingress
and egress across the sidewalk. In order to maintain pedestrian orientation and the continuity of sidewalks within
the C-D zone, the installation of new driveway approaches is subject to the Director’s Action. When new driveway
approaches are proposed in conjunction with an application for review by the Architectural Review Commission, a
separate planning application shall not be required. In order to approve the new driveway approach, the review
authority shall make at least one of the following findings:
1. The proposed driveway approach will not harm the general health, safety, and welfare of people living or
working in the vicinity of the project site because the number of vehicles expected to use the driveway is limited
(fewer than 10 spaces) and there are no other alternatives, such as service alleys, to provide vehicle access
to the site.
2. The proposed driveway approach is located along a nonarterial street and will not significantly alter the
character of the street or pedestrian circulation in the area in consideration of the characteristics of pedestrian
flow to and from the project site and surrounding uses.
3. The proposed driveway approach is a shared facility and provides efficient access to more than a single project
in a way that eliminates the need for additional driveways.
4. The proposed driveway approach provides access to public parking.
C. Residential Required. All new commercial developments in the C-D Zone shall include housing, unless the City
makes one of the following findings:
1. Housing is likely to jeopardize the health, safety, or welfare of residents or employees; or
2. All of the findings listed for Variances in Section 17.114.040 (Required Findings).
Ordinance No. 1650 (2018 Series)
EXHIBIT B
Article 2: Zones
2-30 September 2018
D. C-D Zone – Required Findings for Ground-floor Offices. These regulations recognize the City’s objective to
encourage a pedestrian-oriented and lively street front along all properties in the C-D zone, and that office uses
on the ground-floor do not contribute to achieving this objective, given that office uses typically have more limited
hours of operation than retail or dining establishments. Thus, no ground-floor office use in the C-D zone shall be
permitted unless the review authority can make the following findings:
1. As conditioned, the proposed use will not be detrimental to the health, safety, or welfare of persons living or
working at the site or in the vicinity because the proposed use will provide both retail sales and services
consistent with surrounding uses.
2. The proposed use is consistent with the General Plan Policy 4.20.1 because the nature of the business
includes an office that has frequent client visits which accommodate “walk-in” service for the community, and
also provides visible retail merchandise, thereby benefiting from and contributing to pedestrian traffic.
E. Maximum Building Height in the C-D Zone.
1. Intent of Allowing Height Increases in the C-D Zone. These regulations are established to allow for buildings
higher than 50 feet in the C-D zone to encourage creative building design, mixed-use developments, and
accommodation of additional residential units in the Downtown Core, provided that such taller buildings,
through discretionary review processes, contribute defined community benefits and further the goals of the
Downtown Core as stated in the Land use Element of the General Plan.
2. Requirements for All Buildings Higher Than 50 Feet. All buildings in the C-D zone proposed to be higher
than 50 feet shall comply with all of the following performance standards:
a. The project shall include housing at a minimum residential density unit value of 24 units per acre. The
average floor area of dwellings within the project shall be 1,000 square feet or less. Group housing projects
shall demonstrate that the proposed building meets or exceeds the population density that would otherwise
be achieved by this standard.
b. The applicant shall demonstrate that:
(1) The project is designed to achieve at least a Silver rating on the LEED-CS or NC checklist (or
equivalent measure) (LEED certification is not required but is encouraged); or (2) The project is designed to achieve a minimum value of 50 points on the SLO green build multi-unit
residential greenpoint checklist.
c. No more than 33 percent of the site area at the storefront level may be used for private parking facilities.
d. Lots shall conform to the minimum size and dimension requirements provided in Title 16, Subdivisions.
e. To approve an increase in height above 50 feet, the Planning Commission shall make the following finding:
The public benefits associated with the project significantly outweigh any detrimental impacts from the
additional height. In weighing potential public benefits, the Planning Commission shall consider objectives
related to affordable and workforce housing, mode split, historic preservation, and open space
preservation to be especially important.
f. The Planning Commission may grant minor exceptions to the specific requirements listed in this Section,
and provided a finding is made that, despite the exception, the project is consistent with the intent of this
Chapter and Land Use Element Policy 4.20 (Design Principles).

5. Community Benefits Policy Objectives. The intent of the following policy objectives is to ensure that
buildings taller than 50 feet proposed in the C-D zone include features that meet the specific policy objectives
outlined for tall buildings in the General Plan (including, but not limited to, Land Use Element Chapter 4.0). A
variety of objectives are listed to ensure that proposed project features are appropriate for the site and
surroundings, and to allow for a wide range of possible project types. Regardless of the number of objectives
proposed, the Planning Commission shall determine that the overall project is consistent with the General Plan,
including goals and policies for view preservation, historical resource preservation, solar access, and
architectural character.
a. Affordable and Workforce Housing.
(1) The project provides affordable housing, in compliance with City standards, at the rate of five percent
for low-income households, or 10 percent for moderate-income households, as a percentage of the
total number of housing units built (no in-lieu fee option).
(2) The project qualifies for, and utilizes, a density bonus in compliance with the City’s affordable housing
incentives (Chapter 17.140).
(3) The project includes residential density greater than or equal to 36 units per acre and the average
floor area of units is 1,000 square feet or less. Group housing projects shall show that the proposed
building meets or exceeds the population density that would otherwise be achieved by this objective.
b. Pedestrian Amenities.
(1) The project provides a major pedestrian connection between Higuera Street and the Creekwalk,
Monterey Street and the Creekwalk, Higuera Street and Marsh Street, or at another acceptable mid-
block location.
(2) The project provides open space in the form of a significant public plaza, where:
(a) The minimum area of any public plaza shall be 7,500 square feet; and
(b) The public plaza is owned, operated, and maintained by the developer or property manager in
accordance with an approved maintenance plan to be reviewed and approved by the Director;
and
(c) Each part of the public plaza shall be accessible from other parts of the open space without
leaving the open space area; and
(d) The public plaza shall be on the ground level and directly accessible from the sidewalk, and be
accessible to persons with disabilities; and

(e)The public plaza shall be open to the public, without charge, each day of the year, except for
temporary closures for necessary maintenance or public safety; and
(f)At a minimum, the following elements shall be included within the open space: trees and
landscaping, seating, bicycle racks, trash and recycling receptacles, and signage that include
hours of operation; and
(g)The public art requirement is met by providing the art onsite (no in-lieu fee option).
c.View Access and Preservation.
(1)The project provides a public viewing deck or decks, or similar feature, to provide significant free
public access to views of surrounding natural features such as, but not limited to, Cerro San Luis.
(2)The project improves and dedicates land within the downtown core for publicly owned open space
with street-level views of hillside resources, consistent with Land Use Element Policies 4.10 (Open
Places and Views) and 4.20.4 (Building Height).
d.Historic Preservation (Off Site). Where there are no historic resources on the project site, the project
provides for the permanent preservation of a building off site within the downtown historic district or
Chinatown historic district that is listed in the City’s inventory of historical resources through the recordation
of a historic preservation agreement.
e.Mode Split. The project provides for the permanent mode shift towards alternative transportation for
building occupants through a Transportation Demand Management Program that achieves modal split
objectives of Circulation Element Policy 1.7.1 (Encourage Better Transportation Habits). Prior to the
issuance of building permits, a covenant agreement shall be recorded that discloses the required
Transportation Demand Management provisions. This agreement shall be recorded in the office of the
County Recorder to provide constructive notice to all future owners of the property of any ongoing
programmatic requirements.
f.Open Space Preservation. The project provides for the permanent preservation of open space land in
the City’s greenbelt through land dedication, the recordation of a conservation easement, or other
recognized preservation method, to the approval of the City.
g.Zero Net Energy. The project provides 100 percent of total building energy load measured as kilowatt per
square foot through solar panels, wind turbines, or other renewable sources.
h.Common Garbage Facility. The project provides a common garbage storage and compacting facility of

17.48.010 – Purpose and Application
A. Purpose. The PD overlay zone is intended to provide for flexibility in the application of zoning standards for
proposed development. The purpose is to allow consideration of innovation in site planning and other aspects of
project design—and more effective design responses to site features, land uses on adjoining properties, and
environmental impacts—than the development standards of the underlying zone would produce without adjustment.
The City expects each planned development project to be of significantly higher design quality, including more
effective and attractive pedestrian orientation, environmental sensitivity, affordable housing, and the more efficient
use of resources, than would be achieved through conventional design practices and standards. Planned
Development (PD) zoning shall be approved only in conjunction with derived long-term community benefits and
where the project can help achieve the vision, goals, and policies of the General Plan.
B. Application. The requirements of this Chapter shall apply to all projects within the PD overlay zone.
17.48.020 – Allowed Uses
Any use or combination of uses allowed by Section 17.10.020 (Use Regulations By Zone) within the underlying zone
may be established within the PD overlay zone, subject to any additional limitations on specific land uses provided by
the overlay as adopted. No PD overlay zone shall allow a land use that is not allowed in the underlying zone, or by the
General Plan, or any applicable specific plan.
17.48.030 – Development Standards
A. Minimum Lot Area Required. The minimum lot area of a PD overlay zone shall be one-half of a contiguous acre.
B. General Plan Compliance. The preparation, review, and approval of a PD overlay zone shall require strict
compliance with the General Plan and any applicable specific plan.
C. Relationship of PD Overlay Zone to Underlying Zone.
1. Planning Permit Requirements. Development and new uses within the PD overlay zone shall obtain the
permits required by Section 17.10.020 (Use Regulations By Zone) for the underlying zone.

2. Site Planning and Project Development Standards. Development and new land uses within the PD overlay
zone shall comply with all applicable development standards of the underlying zone, except as specifically
modified, waived, or augmented by the PD overlay zone.
D. Deviation from Development Standards. The application of the PD overlay zone to property may include the
adjustment or modification, where necessary and justifiable, of any applicable development standard of this Title
17 (e.g., building height, floor area ratio, parcel size, parking, setbacks, etc.) or of the City’s subdivision regulations.
The maximum density as allowed by cross-slope percent may be adjusted but shall not exceed the maximum
density allowed in the average cross-slope category zero through 15 percent for the applicable zone.
E. Qualifying Community Benefits. Each proposed project shall comply with Section 17.48.080 (Mandatory Project
Features).
17.48.040 – Phasing
A. Timing of Rezoning. Application of the PD overlay zone shall occur simultaneously with the approval of a specific
project through the planned development process as set forth in Section 17.48.070 (Process for Approval).
B. Phasing. If the construction of the planned development is to occur in phases, the open space and common
facilities shall be developed and made available in proportion to the number of dwelling units or nonresidential floor
area occupied during any given stage. At no time during construction of the project shall the density of developed
land exceed the overall density established in the final development plan.
17.48.050 – Preliminary Development Plan Required
In addition to any application requirements set forth in Chapter 17.04 (Permit Application Filing and Processing), an
application for planned development shall be made to the Community Development Department and shall consist of a
preliminary development plan, to include:
A. A legal description of the total site involved;
B. A statement of the objectives to be achieved by the planned development through the particular approach to be
used by the applicant;
C. A schedule indicating the approximate dates when construction of the development or stages of the development
are to be started and completed;
D. A quantified description of the total number and type of dwelling units, parcel sizes, coverage, modified and natural
open space, grading, residential densities, and areas devoted to nonresidential uses;
E. Identification of portions of the development which would otherwise require a Variance, and reason for the deviation
from normal standards;
F. A site plan and supporting maps, drawn to a suitable scale and clearly labeled, showing if applicable:

A. Purpose. The Mixed Use (MU) overlay zone, in combination with any other zone, requires a mix of residential and
nonresidential uses on the same site where mixed-use development would otherwise be at the discretion of the
property owner. The primary purpose of the MU overlay zone is to provide a means for the City to identify areas
where the public health, safety, and welfare will be enhanced by requiring that all allowed development be in the
form of mixed-use projects, where ground-floor street frontages are occupied by retail, business, or personal
services uses and residential uses are located above or to the rear of a site. The MU overlay zone is intended to
promote a compact city, to provide additional housing opportunities—including affordable housing opportunities—
which is the first priority, and to reduce vehicle travel by providing services, jobs, and housing in proximity. The City
desires the safety provided by having residential components in commercial areas.
B. Application.
1. General. The requirements of this Chapter shall apply to all new development projects, but shall not apply to
additions to existing buildings, expansion of an existing use, or change of use.
2. Initiation. Application of the MU overlay zone may be initiated by the Council or Planning Commission to
ensure that mixed residential and commercial uses will be included when certain parcels are developed or
redeveloped, or by a property owner.
17.58.020 – Allowed Uses
Each land use proposed on a site subject to the MU overlay zone shall be authorized in compliance with the permit
requirements of Section 17.10.020 (Use Regulations By Zone) that apply to the underlying zone, except that new mixed-
use projects that the Director determines are consistent with the standards of this Section shall not require a Minor or
Conditional Use permit for mixed uses.
17.58.030 – Development and Design Standards
Property development standards shall be those of the underlying zone, except that the application of the MU overlay
zone to a property may include establishing a higher height limit than the underlying zone to more effectively
accommodate the residential component of a mixed-use project. Any such request for a higher height limit shall be set
forth in the subject application and shall be reviewed by the applicable review authority as part of the overall application.
Proposed development and new land uses shall also comply with all applicable provisions of Section 17.70.130 (Mixed-

uses is permitted. Nonconforming uses shall comply with Zoning Regulations Chapters 17.92 (Nonconforming
Structures) and 17.94 (Nonconforming Uses) provisions for expiration of nonconforming status and proposed
changes in land use which do not conform to the AOZ.
Development or land uses shall be considered “existing” if one of the following conditions is met:
1. A vesting tentative map has been approved and has not expired or all discretionary approvals have been
obtained and have not expired.
2. Building permits have been issued and have not expired.
3. The structures and site development have been legally established and physically exist. (Ord. 1610 § 5
(part), 2014)
17.64.030 – Procedures
A. Approval. All ministerial and discretionary actions within the airport overlay zone shall be reviewed for consistency
with this Chapter prior to approval.
B. Mandatory Findings for Approval. When a project or activity is subject to discretionary actions requiring a public
hearing or notice, the applicable review authority shall make all of the following findings, as applicable:
1. The project or use complies with the noise compatibility policies of the airport overlay zone (AOZ).
2. The project or use complies with residential and nonresidential density standards in Table 2-24: Airport
Overlay Zone [AOZ] – Maximum Allowed Persons.
3. The project or use complies with Table 2-24 of the applicable airport overlay zone.
4. The project or use complies with the airspace protection policies of the airport overlay zone.
5. The project or use complies with the overflight policies of the airport overlay zone.
C. Amendments. Other than general plan, specific plan, or Zoning Regulations changes addressed through a
previous referral to the San Luis Obispo County regional airport land use commission (ALUC), or any action to
overrule any determination of the ALUC, proposed general plan land use amendments, zoning amendments, and
specific plan amendments that impact density or intensity of development within the airport overlay zone (AOZ)
shall be referred to the airport land use commission for a determination of compatibility with the adopted airport
land use plan.
D. Overrule Provisions. Should the San Luis Obispo County airport land use commission (ALUC) update the San
Luis Obispo County regional airport land use plan (ALUP), the City Council of the City of San Luis Obispo shall
Ordinance No. 1650 (2018 Series)

review the updated ALUP and either make changes to applicable general plan sections, zoning, and implementing
ordinances, or the Council may, pursuant to Public Utilities Code Section 21676(b), overrule the ALUC.(Ord. 1610
§ 5 (part), 2014)
17.64.040 – Development Standards and Uses
Land use compatibility standards are intended to minimize the risk to people and property on the ground as well as to
people in an aircraft in the event of an accident or emergency landing occurring outside the airport boundary.
A. Allowable Uses and Nonresidential Density. Table 2-24 lists the uses that are appropriate in the airport land
use plan safety zones S-1b, S-1c and S-2. Table 2-24 includes maximum density standards for the safety zones
listed above which shall be calculated in accordance with the following method:
1. Nonresidential Density Calculation. Calculations of nonresidential density shall be based on requirements
of Section 17.72.030 (Required Parking Spaces), with the assumption of 1.3 occupants per space and gross
parcel size including adjacent roads to centerline of right-of-way. Nonresidential density shall be calculated
prior to reductions for shared use, trip reduction, bicycle, etc. In determining allowed persons per acre, all
fractions shall be rounded to the nearest whole number.
Example—Proposed Development: Two office buildings, each two stories and containing twenty thousand
square feet of floor area per building. Site size is three net acres. Counting the adjacent road to centerline of
the right-of-way, three and one-half acres gross. The number of people on the property is assumed to equal
1.3 times the number of parking spaces.
The average usage intensity would therefore be calculated as follows:
(1) 40,000 sq. ft. floor area x 1.0 parking space per 300 sq. ft. = 134.
(2) 134 parking spaces x 1.3 persons per space = 174 persons per acre.
(3) 174 persons/3.5 acres gross site size = 50 persons per acre average for the site.
2. Exceptions. Subject to approval of an administrative use permit, the Director may determine another method
of density calculation is appropriate based on the particular characteristics of the proposed use and/or
development. The method of calculation shall remain consistent with recommended methodologies of
Appendix “G” of the California Airport Land Use Planning Handbook.
B. Airport Land Use Plan and Airport Overlay Zone (AOZ). Development and uses within airport land use plan
safety zones S-1b, S-1c, and S-2 are subject to requirements of Chapter 17.64: Airport Overlay Zone (AOZ).
Development and uses within the runway protection zone (RPZ) and ALUP area S-1a shall be consistent with
provisions of the ALUP. Most areas within the airport overlay zone (AOZ) are located within specific plan areas.
Areas within the AOZ which are located in specific plans designated with SP zoning shall follow regulations within
their respective specific plans.
C. Interpretation of Use Listing. The Director, subject to the appeal procedures of Chapter 17.126 (Appeals), shall
determine whether uses which are not listed shall be deemed allowed or allowed subject to use permit approval in
a certain zone that are consistent with the State Aeronautics Act with guidance from the California Airport Land
Use Planning Handbook. This interpretation procedure shall not be used as a substitute for the amendment
procedure as a means of adding new types of uses to Table 2-24.

The safety zone boundaries described within the airport overlay zone are consistent with the adopted San Luis Obispo
County regional airport land use plan. (Ord. 1610 § 5 (part), 2014)
17.64.060 – Airspace Protection
A. Airspace Protection. Airspace protection standards are intended to reduce the risk of harm to people and
property resulting from an aircraft accident by preventing the creation of land use features and prohibition of any
activities that can pose hazards to the airspace used by aircraft in flight. Airspace protection standards regarding
obstruction and hazards to air navigation are defined in the airport land use plan and apply to land uses and
development within the airport overlay zone as summarized below:
1. Objects Affecting Navigable Airspace. Federal Aviation Regulation (FAR Part 77) and Public Utility Code
(PUC) Section 21659 require that structures not penetrate the airspace protection surfaces of the airport
without a permit from the California Department of Transportation or a determination by the Federal Aviation
Administration (FAA) that the object does not constitute a hazard to air navigation or would not create an
unsafe condition for air navigation. The airspace surrounding an airport is divided into segments called
Ordinance No. 1650 (2018 Series)
EXHIBIT B
CITY OF SAN LUIS OBISPO
Title 17 – ZONING REGULATIONS
2-69 September 2018
“imaginary surfaces,” which identify height limits for objects that require further study by the FAA to avoid
creating hazards to air navigation. Structures that have the potential to be considered an obstruction by the
FAA shall be subject to the provisions listed in subsections (A)(1)(a) through (c) of this Section:
a. Proponents of a project shall file a notice of construction or alteration (Form 7460-1) with the Federal
Aviation Administration (FAA) if a proposed structure is more than 200 feet above ground level or may
exceed one foot in height for every 100 feet from the edge of the nearest point on the runway for a distance
up to 20,000 feet. Filing Form 7460-1 with the FAA will initiate an aeronautical study that will ensure a
proposed structure does not constitute a hazard to air navigation or would not create an unsafe condition
for air navigation, including impeding any en route or terminal (airport) instrument procedures as per the
United States Standard for Terminal Instrument Procedures (TERPS) described in FAA Order 8260.3B
(Code of Federal Regulations Section 77.29, Evaluating Aeronautical Effect).
b. Approvals for such projects may include the requirement for an avigation easement, marking or lighting of
the structure, or modifications to the structure. The avigation easement shall be consistent with the form
and content of Exhibit H1 in Appendix H of the California Airport Land Use Planning Handbook.
c. Building permits shall not be issued for a project until a determination of no hazard has been issued by the
FAA and any conditions in that determination are met.
2. Other Flight Hazards Prohibited. Any activities within the airport overlay zone (AOZ) which could pose a
hazard to flight operations, including but not limited to the following:
a. Glare or distracting lights that could be mistaken for airport lights;
b. Sources of dust, heat, steam, or smoke that may impair pilot vision, or light shows, or laser shows or
spotlights;
c. Any emissions that may cause thermal plumes or other forms of unstable air that generate turbulence
within the flight path;
d. Sources of electrical interference with aircraft communications or navigation;
e. Features that create an increased attraction for wildlife that may be hazardous to airport operations such
as attraction of birds to the extent of creating a significant hazard of bird strikes (examples are outdoor
storage or disposal of food or grain, or large, artificial water features; this provision is not intended to
prevent enhancement or protection of existing wetlands or the mitigation of wetlands impacts). Features
which may pose these risks shall be reviewed for consistency with the FAA’s Advisory Circular 150/5200-
33B, Hazardous Wildlife Attractants on or Near Airports; and
f. Entails installation, construction, or enlargement of a structure that constitutes an obstruction to air
navigation through penetration of FAA Part 77 surfaces except as may be approved by the Federal
Aviation Administration (FAA). (Ord. 1610 § 5 (part), 2014)
17.64.070 – Noise
A. Airport Related Noise. Noise compatibility standards are intended to prevent the establishment of noise-
sensitive land uses in portions of the airport environ that are exposed to significant levels of aircraft noise. Where
permitted within the airport overlay zone (AOZ), the following noise-sensitive land uses shall comply with
applicable noise exposure criteria:
Ordinance No. 1650 (2018 Series)
EXHIBIT B
Article 2: Zones
2-70 September 2018
1. Noise analysis from the Airport Master Plan Environmental Impact Report (2006), or subsequent noise analysis
used to update the airport master plan, shall be used for mapping of the long-term noise impact of the airport’s
aviation activity, which includes future planned facilities development depicted in the FAA-approved airport
layout plan. These noise contours are shown in Figure 2-9 (Airport Noise Contours).
a. New Residential Development. New residential uses within the 60 dB CNEL contour as depicted in
Figure 2-9 (Airport Noise Contours) shall demonstrate consistency with maximum noise levels by providing
noise analysis, construction details, or other information deemed necessary by the Director to verify
conformance with maximum interior noise levels.
2. Interior Noise Levels Not to Exceed 45 dB CNEL. For the following noise-sensitive land uses, aircraft-related
interior noise levels shall not exceed 45 dB CNEL (with windows closed):
a. Living or sleeping areas of single or multi-unit residences;
b. Hotels and motels;
c. Hospitals and nursing homes;
d. Places of worship, meeting halls, and mortuaries; and
e. Schools, libraries and museums.
3. Interior Noise Levels Not to Exceed 50 dB CNEL. For the following noise-sensitive land uses, aircraft-
related interior noise levels shall not exceed 50 dB CNEL (with windows closed):
a. Office environments;
b. Eating and drinking establishments; and
c. Other miscellaneous commercial facilities. (Ord. 1610 § 5 (part), 2014)
17.64.080 – Overflight Notice
Aircraft overflight standards are intended to provide overflight notification for land uses near the San Luis Obispo
County regional airport. It shall be the responsibility of all owners of property offered for sale or for lease within the
airport overlay zone (AOZ) to provide a disclosure prior to selling or leasing property in San Luis Obispo as specified
in the airport land use plan.
All discretionary actions shall include a condition of approval requiring all owners of property offered for sale or for
lease within the airport overlay zone to provide the aforementioned disclosure prior to selling or leasing property. For
new residential land uses, the overflight notification shall be recorded and appear with the property deed. (Ord. 1610 §

17.64.090 – Open Land
A. Open Land. Open land areas are intended to increase the chances of a pilot successfully landing an aircraft in an
emergency situation where they are unable to reach the runway. The City has identified properties to contain open
land areas as follows:
1. Airport Area Specific Plan: 250 acres on the Chevron property with two areas specifically improved to meet
ALUC standards; and a 300-foot-wide strip adjacent to Buckley Road (24 acres) on the Avila Ranch site.
2. Margarita Area Specific Plan: two open land areas amid clustered development.
3. Laguna Lake public park open area: outside of AOZ but within the approach surface.
4. Brughelli property easement south of Buckley Road.
5. San Luis Ranch Specific Plan area, west of Highway 101 and south of Dalidio Drive.
6. City open space areas within the airport overlay zone.
Where open space or conservation easements have been obtained and the topography supports it, the City shall not
allow uses to be established that conflict with their availability to be used as a landing option in the event of an
emergency. Where easements have yet to be obtained, the City shall explore opportunities to incorporate the
requirement for open land as part of the discretionary approval process. Open land areas shall be consistent with
ALUP direction for size, orientation, and topography.

A. Purpose.
1. Regulations on accessory structures are established to provide a distinction between nonhabitable accessory
structures (e.g., garage, storage shed, shop building) and accessory living spaces (e.g., secondary dwelling
units, guest quarters, office, pool house, etc.). These regulations establish standards which prevent the
conversion of accessory structures into unpermitted living space to ensure that such structures are not used
as separate dwelling units.
2. Unpermitted conversion of accessory structures is detrimental to the public health, safety, and welfare of the
community.

EXHIBIT B
Article 3: Regulations Applicable to All Zones
3-2 September 2018
B. Applicability. 1. Application. This Section shall apply to:
a. New Structures. All new structures, as defined in the Building Code, located on the same site as the
primary structure or use to which it is accessory, including, but not limited to, garages, carports, porte-
cocheres, sheds, workshops, gazebos, greenhouses, cabanas, trellises, play structures, aviaries,
covered patios, etc.
b. Decks and Patios. Decks and patios that are 30 inches above the ground elevation, excluding
aboveground pools.
2. Exclusion. This Section shall not apply to legally established dwellings, accessory dwelling units as defined
in Section 17.156.004 (A Definitions), and guest quarters as defined in Section 17.158.018 (G Definitions).
Accessory structures that include habitable space, as defined by the California Building Code, shall be
regulated by Section 17.86.020 (Accessory Dwelling Units and Guest Quarters).
C. Development Standards.
1. General Development Standards. Accessory structures shall conform to all applicable Zoning Regulations
such as height, yards, parking, building coverage, etc.
2. Incidental Use. The use of an accessory structure is incidental, and subordinate to the use of the principle
structure, or to the principle land use of the site.
3. Form. Accessory structures may consist of detached structures or additions to primary structures.
4. No Bathing Facilities. No bathing facilities (e.g., shower, bathtub) may be installed. Plans submitted for a
building permit may not include spaces within a bathroom designed for the later addition of bathing facilities.
5. Limit on Total Number in Residential Zones. In residential zones, no more than three accessory structures
shall be permitted per lot, only one of which may include a habitable accessory structure such as an accessory
dwelling unit or guest quarters.
D. Process Requirements.
1. Building Permit. Development of an accessory structure shall require approval of a building permit from the
City’s Building Division.
2. Design Review. Plans submitted for a building permit shall be reviewed for consistency with the City’s
Community Design Guidelines and general development requirements of the Zoning Regulations.
3. Owners Agreement with the City. Prior to the issuance of construction permits, a covenant agreement shall
be recorded that discloses the structure’s approved floor plan and status as an “accessory structure” which
cannot contain living space, including bathing facilities or a kitchen. This agreement shall be recorded in the
office of the County Recorder to provide constructive notice to all future owners of the property. The covenant
agreement also may contain authorization for annual inspections, and to allow the City upon reasonable time
and notice to inspect the premises for compliance with the agreement and to verify continued compliance with
requirements of this Section and Health and Safety Codes.

17.70.030 – Creek Setbacks
A. Purpose. Creek setbacks are intended to:
1. Protect scenic resources, water quality, and natural creekside habitat, including opportunities for wildlife
habitation, rest, and movement;
2. Further the restoration of damaged or degraded habitat, especially where a continuous riparian habitat
corridor can be established;
3. Allow for natural changes that may occur within the creek corridor;
4. Help avoid damage to development from erosion and flooding; and
5. Enable implementation of adopted City plans.
B. Waterways Subject to Setbacks. Creek setback requirements shall apply to all creeks as defined in the General
Plan Open Space Element and shown on that element’s creek map, and only to those creeks.
C. Measurement of Creek Setbacks. Creek setbacks shall be measured from the existing top of bank (or the future
top of bank resulting from a creek alteration reflected in a plan approved by the City), or from the edge of the
predominant pattern of riparian vegetation, whichever is farther from the creek flow line (Figure 3-1: Creek
Setbacks). Top of bank determination shall be consistent with California Department of Fish and Wildlife where
State or Federal jurisdictional areas apply. The Director or Natural Resources Manager may determine the
predominant pattern of riparian vegetation, where the edge of the vegetation varies greatly in a short length along
the creek, in a way unrelated to topography (e.g., the Director will not base the setback line on individual trees or
branches extending out from the channel or on small gaps in vegetation extending toward the channel). Where
riparian vegetation extends over a public street, no creek setback is required on property which is on the side of
the street away from the creek.
D. Plan Information. The location of top of bank and of riparian vegetation shall be shown on all project plans subject
to City approval. The location of these features is subject to confirmation by the Director, based on observation of
actual conditions and, as needed, the conclusions of persons with expertise in hydrology, biology, or geology.
E. Creek Setback Dimensions. Different setback dimensions are established in recognition of different lot sizes and
locations of existing structures for areas within the City in comparison with areas that may be annexed, and in
response to different sizes of the creek channels and tributary drainage areas.
1. Creeks within the 1996 City Limits. Along all creeks within the City limits as of July 1, 1996, the setback
shall be 20 feet, except as provided in subsections E.3, E.4, and G of this Section. Where the City limit follows
a creek, the setback on the side within the 1996 City limits shall be 20 feet, and the setback on the annexed
side shall be as provided in subsection E.2 of this Section.
2. Creeks in Areas Annexed After 1996. Along any creek in an area annexed to the City after July 1, 1996, the
following setbacks shall be provided, unless a specific plan or development plan approved by the Council
provides a larger or smaller setback, consistent with the purpose of these Zoning Regulations and with
General Plan policies:
a. 50-Foot Setbacks. The setback along the following shall be 50 feet: San Luis Obispo Creek (all of main
branch); San Luis Obispo Creek East Fork, from San Luis Obispo Creek (main branch) to the confluence
with Acacia Creek; and Stenner Creek.
Ordinance No. 1650 (2018 Series)
EXHIBIT B
Article 3: Regulations Applicable to All Zones
3-4 September 2018
b. 35-Foot Setbacks. The setback along the following shall be 35 feet: Prefumo Creek; Froom Creek;
Brizziolari Creek; San Luis Obispo Creek East Fork tributary, from the confluence with Acacia Creek to
Broad Street (Highway 227); Acacia Creek and its tributaries west of Broad Street (Highway 227); and
the segment of the tributary of Acacia Creek which flows generally parallel to and on the easterly side of
Broad Street (Highway 227), from Broad Street to Fuller Road.
c. 20-Foot Setbacks. The setback along all creeks except those listed in subsections E.2.a and E.2.b of
this Section shall be 20 feet. (Informational map is available in the Community Development Department.)
3. Additional Upper Story Setbacks. Where the zone allows more than two stories, an additional 10-foot step
back (upper story building setback) shall be provided beginning at the third story level. The upper story step
back shall be provided along all building elevations with creek-facing frontage.
4. Larger Setbacks. To mitigate potentially significant environmental impacts in compliance with the California
Environmental Quality Act, or to implement adopted City plans, when approving a discretionary application
the City may require setbacks larger than required by subsections E.1 and E.2 of this Section, or further
limitations on the items which may be placed within setbacks. Also, other City regulations may restrict or
prevent development in a floodway or floodplain.
5. Prior Approvals. Where the City has explicitly approved a creek setback smaller than required by this Section
prior to adoption of these regulations, that smaller setback shall remain in effect so long as the approval is in
effect.
F. Improvements Prohibited within Setbacks. The following shall not be placed or constructed within a creek
setback, except as provided in subsection G of this Section:
1. Structures larger than 120 square feet
2. Paving
3. Parking lots
4. Fire pits, barbeques, and other open flames
5. Mechanical equipment
6. In nonresidential zones, areas used for storing or working on vehicles, equipment, or materials
G. Exceptions to Creek Setbacks.
1. Replacement Structures. Where a structure lawfully existed on or before October 3, 1996 within a creek
setback required by this Section, the provisions of this Section shall apply. This part is not intended to allow
replacement of paving that existed on or before October 3, 1996 with new paving or a building, unless a
discretionary approval is obtained in compliance with subsection G.4 of this Section.
a. Any structure built in replacement of such a structure may occupy the same footprint, within the creek
setback, as the previous structure, without obtaining a discretionary exception. See also Section
17.70.170.D.1.b (Reduced Front or Street Side Setback for New Structure Providing Additional Creek
Setback).
b. Additional floor area shall not be added to the encroaching part of the structure (e.g., by adding stories).

c. The part of a structure that is nonconforming due solely to the creek setback encroachment may be
remodeled without regard to the limits of Section 17.92.020 (Limits on Reconstruction – Exceptions) of
these Zoning Regulations.
2. Accessory Structures and Uses. The following items may be located within the required creek setback
without obtaining a discretionary exception unless otherwise noted, provided, that they do not extend beyond
the top of bank into the creek channel; will not cause the removal of native riparian vegetation; will not reduce
any flooding capacity in compliance with the City’s flood damage prevention regulations; in total occupy not
more than one-half of the total required creek setback area; and are consistent with other property
development standards of the Zoning Regulations.
a. Walls or fences, provided that in combination with buildings they enclose not more than one-half of the
setback area on any development site.
b. For a single-unit dwelling: uncovered parking spaces.
c. Patios and pervious walkways. However, impervious pedestrian walkways and bicycle paths shall require
a Director’s Hearing as provided in subsection G.4. of this Section.
d. Decks, stairs, and landings that are no more than 30 inches in height, as measured from adjacent existing
grade.
e. One-story, detached buildings used as tool and storage sheds, play houses, and similar uses, provided
the projected roof area does not exceed 120 square feet. No more than one such building is allowed per
parcel.
f. Garden structures such as trellises, arbors, and gazebos, provided they are constructed using an open
lattice design and light-weight materials.
g. Picnic tables and benches.
h. Natural flood control and stormwater improvements, including vegetated buffers, bioswales, and rain
gardens.
3. Architectural Features. The following architectural features may extend into the setback up to thirty inches:
cornices, canopies, eaves, buttresses, chimneys, solar collectors, shading louvers, water heaters and related
enclosures, and bay or other projecting windows that do not include usable floor space.
4. Director’s Hearing for Exceptions.
a. Intent. The Director, through a Director’s Hearing, may act to approve an exception to the creek setback
requirements of this Section only where the applicant can provide clear and substantiated evidence that
there is no practical way to comply with the provisions and that no other feasible alternatives will result in
better implementation of other Zoning Regulations or General Plan policies while allowing reasonable
use of sites subject to creek setbacks.
b. Application Type. A creek setback smaller than required by this Section may be approved by City action
on a plan for public facilities approved by the Council or on a specific plan, development plan under
planned development zoning, or land division, use permit, or architectural review. Where one of these
types of applications is not otherwise required for the proposed feature, an exception request shall be in
the form of a Director’s Hearing.
Ordinance No. 1650 (2018 Series)
EXHIBIT B
Article 3: Regulations Applicable to All Zones
3-6 September 2018
c. Findings. Each Director’s Hearing or other discretionary application to grant an exception to a required
creek setback shall be subject to each of the following findings, in addition to any other required findings
associated with the project application under which the request is considered:
(1) The location and design of the feature receiving the exception will minimize impacts to scenic
resources, water quality, and riparian habitat, including opportunities for wildlife habitation, rest, and
movement; and
(2) The exception will not limit the City’s design options for providing flood control measures that are
needed to achieve adopted City flood policies; and
(3) The exception will not prevent the implementation of City-adopted plans, nor increase the adverse
environmental effects of implementing such plans; and
(4) There are circumstances applying to the site, such as size, shape, or topography, which do not apply
generally to land in the vicinity with the same zoning, that would deprive the property of privileges
enjoyed by other property in the vicinity with the same zoning; and
(5) The exception will not constitute a grant of special privilege—an entitlement inconsistent with the
limitations upon other properties in the vicinity with the same zoning; and
(6) The exception will not be detrimental to the public welfare or injurious to other property in the area
of the project or downstream; and
(7) Site development cannot be feasibly accomplished with a redesign of the project; and
(8) Redesign of the project would deny the property owner reasonable use of the property. “Reasonable
use of the property” in the case of new development may include less development than indicated
by zoning. In the case of additional development on an already developed site, “reasonable
development” may mean no additional development considering site constraints and the existing
development’s scale, design, or density.
d. Biological Survey. A biological survey by a qualified, independent person shall be required for each
creek setback exception request to provide the basis for making the required findings above, unless
waived by the Director upon determining that no purpose would be served by such a survey because no
biological resources could be affected by the exception.

A. Determination of Allowed Development.
1. Density Calculation – General. In the AG, C/OS, R-1 zones, each single-unit dwelling counts as one density
unit. In the other zones, different size dwellings have density unit values as follows:
a. Studio and one-bedroom dwellings less than 600 square feet = 0.50 unit;
b. One-bedroom dwellings between 601 and 1,000 square feet = 0.66 unit;
c. Two-bedroom dwelling = 1.00 unit;
d. Three-bedroom dwelling = 1.50 units;
e. Dwelling with four or more bedrooms = 2.00 units.

2. Maximum Development Density – Sloped Sites.
a. General. In all zones, unless otherwise specified, the maximum development density allowed on a given
lot or land area shall be based on the average cross-slope of the site (see Section 17.70.090.B: Average
Cross-Slope Calculation) and as follows:
Table 3-1: Maximum Residential Density for Cross-Slope Categories
Average Cross-Slope in % Maximum Density Allowed (units per net acre)

Regulations for that zone.
21 – 25 2 4 6 8 As allowed in the Zoning
Regulations for that zone.
26+ 1 2 3 4 As allowed in the Zoning
Regulations for that zone.
b. Exceptions. The Director, through a Director’s Action, may act to approve an exception to the reduction
of density with slope where the parcel in question is essentially enclosed on all sides by development at
least as dense and within the same cross-slope category as the proposed development. The exception
shall not authorize density greater than that allowed for the category of less than 15 percent slope for the
appropriate zone. (See also Section 17.96.020.D, Nonconforming Lots – Regulations.)
3. Maximum Residential Development Potential. Maximum residential development potential shall be the net
lot area (in whole and fractional acres), multiplied by the maximum density allowed (in density units per acre)
according to Subsections A.1 through A.2, above. The resulting number (in density units, carried out to the
nearest one hundredth unit) will be the maximum residential development potential. Any combination of
dwelling types and numbers may be developed, so long as their combined density unit values do not exceed
the maximum potential.
B. Density Transfer.
1. PD Overlay Zone. Development potential may be transferred within the area covered by a planned
development (PD) overlay zone, in conformance with the requirements of Chapter 17.48: Planned
Development (PD) Overlay Zone.
2. C/OS Zone. Where a portion of a lot is within a zone or zones that allow residential use and the rest of the lot
is in a C/OS zone, and the portion within the C/OS zone is not large enough to allow one dwelling, the fractional
dwelling unit potential from the C/OS zone may be transferred to the other portion of the lot, without planned
development rezoning.
C. Density Averaging. Where portions of a lot are within two or more different zones that allow different maximum
densities, and any portion is not of the size required for a lot in that zone, density may be averaged over the whole
lot, with each portion contributing to the overall maximum development potential in proportion to its area and
maximum allowed density.

affordable to households with very low, low, or moderate income, as defined in the Government Code, and as
stipulated in Chapter 17.140: Affordable Housing Incentives of these regulations.
E. Density in Hotels. For hotels and motels, maximum density includes dwelling units located in hotels and motels,
but does not include other hotel or motel units/rooms.
17.70.050 – Edge Conditions
A. Purpose. The edge conditions regulations support a buffer between low-density residential zones or open space
areas and zones that permits development of higher intensity. Where multi-unit residential zones or commercial
zones are adjacent to lower intensity residential or open space zones, development shall incorporate elements in
the site design and building design to soften its impact and to result in a compatible transition to the sensitive zone.
B. Applicability. The standards below apply to any portion of property located within any zone designated in Table
3-2: Edge Condition Zones as “Zones Providing Transition” that are adjacent to a parcel designated in Table 3-2:
Edge Conditions Zones as “Zones Receiving Transition”. For the purposes of this Section, the term “adjacent”
shall not include any properties separated by a street, alley, or other right-of-way, whether public or private.

transition. When located in proximity to residential uses in zones receiving transition, techniques such as block
walls, enhanced setbacks, or enclosed loading or equipment shall be used to minimize adverse impacts from
vehicular noise and noise from mechanical equipment.
17.70.060 – FAR Measurement and Exceptions
A. Measurement – Generally. Floor area ratio (FAR) maximums are applied to buildings in the R-1 zone and all
nonresidential zones. The floor area of a building consists of the sum of the gross horizontal areas of all floors of
a building or other enclosed structure, measured from the outside perimeter of the exterior walls and/or the
centerline of interior walls. In a mixed-use building, floor area ratio maximums apply to both the residential and the
nonresidential components of the development.
B. Single-Unit Residential Floor Area. The floor area for single-unit dwellings shall be measured as the total
horizontal floor area of all the floors of a building from the outside walls. The total horizontal floor area shall include
the residential floor area of any building(s) located on the lot including the main dwelling, detached accessory
structures, all garage area except as exempted below, and enclosed patios. The following shall be excluded from
floor area for the purposes of calculating floor area ratio:
1. Floor area shall exclude required parking spaces in a garage (with each required parking space not exceeding
250 square feet) but shall include any additional enclosed parking spaces provided in addition to the minimum
requirements.
2. Floor area shall exclude fully subterranean basements.
3. Floor area shall exclude non-enclosed covered structures such as decks, patios, porches, and balconies
enclosed on three or fewer sides.
4. Floor area shall exclude legally allowed accessory dwelling units.
C. Non-Residential Floor Area. The floor area shall include the total horizontal floor area of all the floors of a building
measured from the outside walls, exclusive of vents, shafts, courts, elevators, stairways, mechanical, electrical,
and communications equipment, and similar facilities. Floor area shall include mezzanine and lofts. The following
shall be excluded from floor area for the purposes of calculating floor area ratio.
1. Floor area shall exclude required parking areas in a garage (with each required parking space not exceeding
200 square feet) but shall include any additional enclosed parking spaces provided in addition to the minimum
requirements.

17.70.070 – Fences, Walls, and Hedges
A. Purpose. The purpose of these regulations is to achieve a balance between concerns for privacy and public
concerns for enhancement of the community appearance, visual image of the streetscape, overall character of
neighborhoods, and to ensure the provision of adequate light, air, and public safety.
B. Application. These regulations apply to any type of visible or tangible obstruction that has the effect of forming a
physical or visual barrier between properties or between property lines and the public right-of-way, including but
not limited to: any type of artificially constructed barriers of wood, metal, or concrete posts connected by boards,
rails, panels, wire or mesh, and any type of natural growth such as hedges and screen plantings.
C. Standards for Fences Located within Required Setbacks. Fences, walls or hedges may be placed within
required setbacks, provided they do not exceed maximum height limitations and comply with the following
standards:
1. Fence Height within Front Setback. The maximum height of a fence, wall, or hedge shall not exceed six
feet; except within any front setback, the maximum fence, wall, or hedge height shall be as shown in Figure

or rear setback shall be six feet.
5. Arbors, Trellises, and Ornamental Features.
a. General. Arbors, trellises, and other similar ornamental features are allowed within a required setback
subject to the same height limits that apply to fences, walls, and hedges, except as provided in subsection
C.5.b of this Section, below.
b. Street Side and Front Setback. Up to one arbor, trellis, or other similar ornamental feature per street
frontage is allowed with a maximum height of nine feet, and an area of not more than forty square feet
as measured by the perimeter formed by the vertical projection to the ground of the outermost elements
of the feature, and no horizontal dimension shall exceed eight feet in length. Any portion of such a feature
wider than 18 inches and that exceeds the usual fence height requirements of this Section shall be of an
open design such that a person standing on the adjacent public right-of-way can see completely through
at least 50 percent of the structure to the depth of the required street yard (see Figure 3-5: Arbors in Front
and Street Side Setbacks.) Such features within required setbacks shall not be connected to another
structure or building. For the purposes of this Section, the term “connected” shall include structures that
are rigidly joined by structural components. Such features within required setbacks shall not be
constructed of heavy materials such as masonry or metal. Such features within required setbacks comply
with Section 17.70.210 (Vision Clearance Triangle at Intersections).

incorporated into the design of conforming fences or walls may exceed the required height limit up to 18
inches, provided that the decorative element is not wider than 18 inches and that such elements are used to
define a gateway or other entryway or are otherwise at least four feet apart.
D. Standards for Fences Located Outside of Required Setback Areas. Fences, walls, and arbors may be placed
outside required setbacks, provided:
1. The maximum fence, wall, arbor or hedge height is eight feet.
2. Where the fence, wall, or arbor is connected to and a part of a building, it may be any height allowed in the
underlying zone.
E. Fence Height with Difference in Grade. Fence height is measured from the adjacent grade along the lower side
of the wall, fence, or hedge, directly at the base of the wall or fence.
F. Measurement of Height Where Fences or Walls Are Located on Retaining Walls.
1. Where fences or walls are located on retaining walls, the height of the retaining wall shall be considered as
part of the overall height of the fence or wall. Walls or fences must have a minimum spacing of five feet
between each other to be considered separate structures for purposes of measuring overall height
2. Where fences are located on a berm or mound, the height of the fence shall include the berm or mound
directly beneath the fence and above natural grade in the overall height measurement.
3. Where fences are located on retaining walls within interior side or rear setbacks, fences shall not exceed six
feet as measured from the uphill side if erected or replaced on top of the retaining walls, and the combined
fence and retaining wall height shall not exceed nine feet from the lower side, provided no modification of
grade has occurred from the original subdivision improvements and/or design approvals. A building permit is
required for the combined fence and retaining wall height that exceed six feet. If there is evidence that a
modification to the grade has occurred from the original subdivision/design approvals, the height must be
authorized through a fence height exception pursuant to Chapter 17.108 (Director’s Action). For retaining
walls in hillside areas, see also Section 17.70.090.C.3 (Retaining Walls).
G. Intersection and Driveway Visibility. Notwithstanding other provisions of this Section, fences, walls, and hedges

not limited to, issues related to topography and privacy.
17.70.080 – Height Measurement and Exceptions
A. Residential and Nonresidential Building Height on Flat Lots. For flat lots and lots with an average (cross-
parcel) slope of less than 16 percent, the height of a building or structure shall be measured as the vertical distance
from the average level of highest and lowest existing grade of that portion of the site covered by the building to the
topmost point of the roof, including parapets but excluding features outlined in subsection C of this Section. The
average level of the ground is determined by adding the elevation of the lowest point of the part of the lot covered
by the building to the elevation of the highest point of the part of the lot covered by the building and dividing by
two. Height measurements shall be based on existing topography of the site, before grading for proposed onsite
improvements. (See Figure 3-6: Measurement of Structure Height: Flat Ground and Slopes of Less than 15
Percent.)
Figure 3-6: Measurement of Structure Height: Flat Ground and Slopes of Less than 15 Percent
B. Building Height on Slopes with 16 Percent Grade or Greater. For lots with an average (cross-parcel) slope of
16 percent or greater, the height of a building or structure shall be measured as the vertical distance from the
adjacent existing grade to the topmost point of the roof, including parapets but excluding features outlined in
subsection C of this Section. The maximum allowable height shall be measured as the vertical distance from the
existing grade of the site to an imaginary plane located at the allowed height above and parallel to the grade.
Height measurements shall be based on existing topography of the site, before grading for proposed onsite
improvements. (See Figure 3-7 Measurement of Structure Height: Slopes of 16 Percent of Greater.)

17.70.090 – Hillside Development Standards
A. Purpose and Application.
1. Purpose. The purpose of this Section is to implement goals of the Conservation and Open Space and Land
Use Elements of the General Plan:
Ordinance No. 1650 (2018 Series)
EXHIBIT B
CITY OF SAN LUIS OBISPO
Title 17 – ZONING REGULATIONS
3-17 September 2018
a. To protect and preserve scenic hillside areas and natural features such as the volcanic morros, ridge
lines, plant communities, rock outcroppings and steep slope areas that function as landscape backdrops
for the community;
b. To avoid encroachment into sensitive habitats or unique resources as defined in the Conservation and
Open Space Element;
c. To protect the health, safety and welfare of community residents by directing development away from
areas with hazards such as landslides, wildland fires, flooding and erosion; and
d. To protect the City’s scenic setting.
2. Application. The provisions of this Section shall apply to all lots and sites that have an average cross slope
of 16 percent or more (see Section 17.70.090.B: Average Slope Calculation). The Director may require a
survey and slope analysis to determine whether the provisions of this Section apply to a specific property or
development. Notwithstanding the requirements of this Section, a lot created pursuant to the Subdivision Map
Act and Title 16 (Subdivisions) of the San Luis Obispo Municipal Code prior to the effective date of this division
may be developed with a single unit structure in compliance with other applicable requirements of these
Zoning Regulations.
B. Average Cross-Slope Calculation. Average cross-slope is the ratio, expressed as a percentage of the difference
in elevation to the horizontal distance between two points on the perimeter of the area for which slope is being
determined. The line along which the slope is measured shall run essentially perpendicular to the contours.
1. Where a site does not slope uniformly, average cross-slope is to be determined by proportional weighting of
the cross-slopes of uniformly sloping subareas, as determined by the Director.
2. Cross-slope determinations shall be based on the existing topography of the net site area after subtracting
the area for any future onsite grading necessary to accommodate proposed right-of-way improvements and
other onsite improvements.
3. Cross-slope shall be calculated only for the net area as defined in Section 17.70.110 (Lot Area).
C. Hillside Development Standards.
1. General Site Planning Standards. To assist in maintaining a natural appearance for hillsides and ridgelines,
each structure shall be located in the most accessible, least visually prominent, most geologically stable
portion or portions of the site, at the lowest feasible elevation, and shall, at a minimum, meet the following
requirements:
a. See Section 17.70.040.A.2 (Maximum Development Density – Sloped Sites) for maximum density in
hillside areas.
b. See Section 17.70.090.B (Building Height on Slopes with 16 Percent Grade or Greater) for maximum
height in hillside areas.
2. Site Access and Driveways. Each driveway shall not have a grade steeper than five percent within 10 feet
of a garage or carport entry. Driveway finished grade shall not exceed an average of 15 percent, or 20 percent
at any point.

3. Retaining Walls. Retaining walls that are 20 feet in length shall be limited to six feet in height (above
ground/visible portion). Retaining walls longer than 20 feet shall be limited to four feet in height (above
ground/visible portion). A minimum five-foot horizontal separation is required between retaining walls. For
exceptions, see subsection D of this Section.
4. Downhill Building Walls. No single building wall on the downhill side of a house shall exceed 15 feet in
height above grade. Additional building height on a downhill side are allowed in 15-foot increments, where
each increment is stepped-back from the lower wall a minimum of 10 feet.
5. Height of Lowest Floor Level, Decks, and Support Structures. See Figure 3-8: Height Limit for Lowest
Floor, Decks, and Support Structures.
a. Lowest Floor Level. The vertical distance between the lowest point where the foundation meets grade
and the lowest floor line of the structure shall not exceed six feet.
b. Decks. No portion of the walking surface of a deck with visible underpinnings shall exceed a height of six
feet above grade.
c. Support Structures. Support structures (e.g., columns, pilings, etc.) below the lowest floor on the
downhill side of a house shall be enclosed unless visible structural members are an integral feature of
the architectural design. Support structure wall surfaces shall not exceed six feet in height.
Figure 3-8: Height Limit for Lowest Floor, Decks, and Support Structures
6. Exterior Wall Surfaces.
a. Single-story and small-scale elements, setbacks, overhangs, roof pitches, and/or other means of
horizontal and vertical articulation shall be used to create shade and shadow and break up otherwise
massive forms to minimize the apparent size of exterior wall surfaces visible from public rights-of-way.
b. Large flat building planes are prohibited; the spatial arrangement of the building, including roof overhangs,
shall be used to achieve alternating light and dark building surfaces that will blend with similar contrasts
found in the surrounding natural vegetation.

7. Mechanical Equipment. Mechanical equipment may be placed on rooftops or below a deck only if the
equipment is not visible from the public right-of-way or adjacent properties, except for solar collectors that are
compatible with the roof line and architecturally integrated with the structure.
8. Fencing. Hillside area perimeter fencing that is visible from off-site vantages, except on side and rear yards
that are directly adjacent to living areas on adjacent lots, shall be of a semitransparent, rather than solid
design. Semitransparent material includes, but is not limited to, wrought iron, split rail, and four-inch square
welded wire. In side and rear yards between living areas on adjacent lots, solid, opaque fencing is allowed.
However, the preference is for a more naturalistic approach to screening in the side yards, with semi-
transparent fencing combined with landscaping, or landscaping alone.
D. Director’s Action. The Director may grant exceptions to standards of this Section as set forth in Chapter 17.108
(Director’s Action), subject the following additional findings:
1. Intent. The Director, through a Director’s Action, may act to approve an exception to the hillside requirements
of this Section only where the applicant can provide clear and substantiated evidence that there is no practical
way to comply with the provisions and that no other feasible alternatives will result in better implementation of
other Zoning Regulations or General Plan policies while allowing reasonable use of sites subject to hillside
regulations.
2. Application Type. A hillside regulation less than required by this Section may be approved by City action on
a plan for public facilities approved by the Council or on a specific plan, development plan under planned
development zoning, land division, use permit, or architectural review. Where one of these types of
applications is not otherwise required for the proposed feature, an exception request shall be in the form of a
Director’s Action.
3. Findings. Each Director’s Action to grant an exception to a required hillside regulation shall be subject to
each of the following findings, regardless of the type of project application under which the request is
considered:
a. The proposed alternative complies with and furthers the intent of this Section; and
b. The proposed alternative provides a design solution that is equivalent to or better than the standards
prescribed in this Section for quality, effectiveness, durability, and safety; and
c. The location and design of the feature receiving the exception will minimize impacts to scenic resources
and will not hinder opportunities for wildlife habitation, rest, and movement; and
d. The exception will not prevent the implementation of City-adopted plans, nor increase the adverse
environmental effects of implementing such plans; and
e. There are circumstances applying to the site, such as size, shape, or topography, which do not apply
generally to land in the vicinity with the same zoning, that would deprive the property of privileges enjoyed
by other property in the vicinity with the same zoning; and
f. The exception will not constitute a grant of special privilege—an entitlement inconsistent with the
limitations upon other properties in the vicinity with the same zoning; and
g. The exception will not be detrimental to the public welfare or injurious to other property in the area of the
project; and
Ordinance No. 1650 (2018 Series)
EXHIBIT B
Article 3: Regulations Applicable to All Zones

h. Site development cannot be feasibly accomplished with a redesign of the project or redesign of the project
would deny the property owner reasonable use of the property. “Reasonable use of the property” in the
case of new development may include less development than indicated by zoning. In the case of
additional development on an already developed site, “reasonable development” may mean no additional
development considering site constraints and the existing development’s scale, design, or density.

17.70.170 – Setbacks
A. Purpose. This Section establishes standards for the measurement of setbacks and required setback areas. These
provisions, in conjunction with other applicable provisions of the Zoning Regulations, are intended to help
determine the pattern of building masses and open areas within neighborhoods. They also provide separation
between combustible materials in neighboring buildings. Setback areas are further intended to help provide
landscape beauty, air circulation, views, and exposure to sunlight for both natural illumination and use of solar
energy.
B. Measurement of Setbacks.
1. General. All setback distances shall be measured at right angles from the designated property line to the
building or structure, and the setback line shall be drawn parallel to and at the specified distance from the
corresponding front, side, or rear property line. Exception: Where the front property line is located beyond the
curb (i.e., within a street or common driveway), the front setback is defined as the minimum distance between
a structure and the edge of curb.
2. Building Height and Setbacks. The height of a building in relation to setback standards is the vertical
distance from the ground to the top of the roof, measured at a point that is a specific distance (the setback
distance) from the property line. Height measurements shall be based on the existing topography of the site
Ordinance No. 1650 (2018 Series)
EXHIBIT B
CITY OF SAN LUIS OBISPO
Title 17 – ZONING REGULATIONS

to maintain at least 10 feet of separation between buildings on adjacent parcels and the development
will comply with solar access standards of General Plan Conservation and Open Space Element
Policy 4.5.1; or
(2) When the reduction is for either a minor addition to an existing legal structure that is nonconforming
with regard to side and rear setback requirements or for a detached single-story accessory structure,
provided that all such minor additions and new accessory structures shall comply with applicable
provisions of Title 15, Building and Construction (see also Chapter 17.92, Nonconforming Structures)
and the Director makes the following findings:
(a) In the case of a minor addition, that the minor addition is a logical extension of the existing
nonconforming structure;
(b) In the case of a detached single-story accessory structure (either new or replacing a previously
approved nonconforming structure), that the accessory structure is consistent with the traditional
development pattern of the neighborhood and will have a greater front and/or street side setback
than the main structure;
(c) That adjacent affected properties will not be deprived of reasonable solar exposure, and the
development will comply with solar access standards of General Plan Conservation and Open
Space Element Policy 4.5.1;
(d) That no useful purpose would be realized by requiring the full setback;
(e) That no significant fire protection, emergency access, privacy, or security impacts are likely from
the addition; and

of this subsection, above.
e. Side and Rear Setback Building Height Exceptions. Upon approval of a Director’s Action, the Director
may allow exceptions to the side and rear setback standards provided in Article 2 for each zone. Such
exceptions may be granted in any of the following and similar circumstances, but in no case shall
exceptions be granted for less than the minimum setback required:
(1) When the property that will be shaded by the excepted development will not be developed or will not
be deprived of reasonable solar exposure, considering its topography and zoning;
(2) When the exception is of a minor nature, involving an insignificant portion of total available solar
exposure;
(3) When the properties at issue are within an area where use of solar energy is generally infeasible
because of landform shading;
(4) When adequate recorded agreement running with the land exists to protect established solar
collectors and probable collector locations;
(5) When the property to be shaded is a street;
(6) Where no significant fire protection, emergency access, privacy or security impacts are likely to result
from the exception.
(7) The development will comply with solar access standards of General Plan Conservation and Open
Space Element Policy 4.5.1.

A. Purpose. The purposes of this Chapter are to:
1. Ensure that adequate off-street parking is provided for new land uses and major alterations to existing uses,
considering the demands likely to result from various uses, combinations of uses, and settings, and to avoid
the negative impacts associated with spillover parking into adjacent neighborhoods and districts;
2. Minimize the negative environmental and urban design impacts that can result from parking lots, driveways,
and drive aisles within parking lots;
3. Offer flexible means of minimizing the amount of area devoted to vehicle parking by allowing reductions in the
number of required spaces in transit-served locations, shared parking facilities, and other situations expected
to have lower vehicle parking demand;
4. Where possible, consolidate parking and minimize the area devoted exclusively to parking and driveways
when typical demands may be satisfied more efficiently by shared facilities;
5. Ensure that parking and loading areas are designed to operate efficiently and effectively and in a manner
compatible with onsite and surrounding land uses; Ensure that adequate off-street bicycle parking facilities
are provided;
6. Promote parking lot designs that offer safe and attractive pedestrian routes;
7. Encourage bicycling, transit use, walking, carpooling, and other modes of transportation (other than by motor
vehicle) that can move the City toward achieving modal split goals in the General Plan Circulation Element;
and
8. Accommodate and encourage increased use of alternative fuel and zero-emissions vehicles.
B. Applicability. The minimum off-street parking spaces established in this Section shall be provided for new
construction or intensification of use, and for the enlargement or increased capacity and use of land.

Article 3: Regulations Applicable to All Zones
3-46 September 2018
17.72.020 – General Provisions
A. Requirements by Type of Use. Except as otherwise provided in these Zoning Regulations, for every structure
erected or enlarged and for any land or structure devoted to a new use requiring more spaces according to the
schedule set out in this Chapter, the indicated minimum number of off-street parking spaces located on the site of
the use shall be provided. The right to occupy and use any premises shall be contingent on preserving the required
parking and maintaining its availability to the intended users, including residents, staff, and/or customers. In no
case shall required parking spaces for a use be rented or leased to off-site uses or used for other purposes, unless
allowed by subsection D (Unbundling Parking) of this Section.
Additional parking or alternative parking development standards, may be required as a condition of use permit
approval.
B. Uses Not Listed. The Director shall determine the parking requirement for uses that are not listed in Table 3-4:
Parking Requirements by Use. The Director’s determination shall be based on similarity to listed uses; that decision
may be appealed to the Planning Commission.
C. Parking Calculations.
1. Floor Area. The parking requirement calculation shall be based on the gross floor area of the entire use,
unless stated otherwise.
2. Sites with Multiple Uses. If more than one use is located on a site (including a mix of uses or a mixed-use
development), the number of required onsite parking spaces and loading spaces shall be equal to the sum of
the requirements calculated separately for each use unless a reduction is approved pursuant to Section
17.72.050 (Parking Reductions).
D. Unbundling Parking. This section authorizes the separating, or “unbundling”, of parking areas from the use or
uses the parking is intended to serve by leasing those spaces separately from such residential unit or
nonresidential use. The purpose of allowing for unbundled parking is to move toward the City’s goal of encouraging
travel mode shift away from single-user private motor vehicles.
1. Residential Uses. Residential projects may unbundle the parking from the residential uses with approval of
a Director’s Action (Chapter 108: Director’s Action), and the following rules shall apply to the sale or rental of
onsite parking spaces unless waived by the Director as infeasible:
a. All off-street parking spaces shall be leased or sold separately from the rental or purchase fees for
dwelling units for the life of the dwelling units, such that potential renters or buyers have the option of
renting or buying a residential unit at a price lower than would be the case if there were a single price for
both the residential unit and the parking space.
b. Renters or buyers of onsite inclusionary affordable units shall have an equal opportunity to rent or buy a
parking space on the same terms and conditions as offered to renters or buyers of other dwelling units.
2. Nonresidential Uses. Nonresidential projects may unbundle the parking from nonresidential use with
approval of a Director’s Action (Chapter 17.108: Director’s Action), and the following rule shall apply to the
sale or rental of onsite parking spaces unless waived by the Director as infeasible: All off-street parking
spaces shall be leased or sold separately from the rental or purchase fees for each nonresidential space for
the life of the space, such that potential tenants or buyers have the option of renting or buying the
nonresidential square footage at a price lower than would be the case if there were a single price for both
the floor area and the parking space.

17.72.050 – Parking Reductions
A. Affordable Housing Developments. See Chapter 17.140: Affordable Housing Incentives.
B. Shared Parking Reduction. Where a shared parking facility serving more than one use will be provided, the total
number of required parking spaces may be reduced by up to 20 percent with Director approval via Director’s Action
(Chapter 17.108), if the Director finds that:
1. The peak hours of use will not overlap or coincide to the degree that peak demand for parking spaces from
all uses or projects will be greater than the total supply of spaces;
2. The proposed shared parking provided will be adequate to serve each use and/or project;
3. A parking demand study conducted and prepared under procedures set forth by the Director supports the
proposed reduction; and
4. In the case of a shared parking facility that serves more than one property, a parking agreement has been
prepared and recorded with the Office of the County Recorder, requiring the parking to be operated on a
nonexclusive basis, to be open and available to the public for shared use, short-term parking during normal
business hours.
C. Other Parking Reductions. Required parking for any use may be reduced by up to 10 percent through Director
approval of a Director’s Action. Required parking may be reduced by more than 10 percent through Planning
Commission approval. However, no reduction shall be made in addition to any reductions for shared parking
permitted through subsection B (Shared Parking Reduction) of this Section, above.
1. Criteria for Approval. The review authority may only approve a request reduced parking if it finds that:
a. Special conditions, including but not limited to, the nature of the proposed operation; proximity to frequent
transit service; proximity to a general market, transportation characteristics of persons residing, working,
or visiting the site; or because the applicant has undertaken a transportation demand management
program that provides justification of innovative design components and strategies to reduce single-
occupant vehicle travel to and from the site and will reduce parking demand at the site
b. The use will adequately be served by the proposed onsite parking; and
c. Parking demand generated by the project will not exceed the capacity of or have a detrimental impact on
the supply of on-street parking in the surrounding area.
2. Parking Demand Study. In order to evaluate a proposed project’s compliance with the above criteria, a
parking demand study shall be conducted and prepared under procedures set forth by the Director that
substantiates the basis for granting a reduced number of spaces.
3. Reduction Rates. The review authority may consider the following rates for parking reductions associated
with a parking demand study:
a. One car space for each five motorcycle spaces provided in excess of required parking.
b. One car space for each five bicycle spaces provided in excess of required parking. All bicycle parking
that exceeds the required number of spaces shall be apportioned between short-term and long-term
bicycle spaces as stipulated by Table 3-6: Required Bicycle Parking. Any additional bicycle parking
provided for residential uses shall be covered.
Ordinance No. 1650 (2018 Series)
EXHIBIT B
Article 3: Regulations Applicable to All Zones
3-54 September 2018
4. Vehicle Trip Reduction Plan. Based on the parking study, the Director may require implementation of a
vehicle trip reduction plan and such other conditions deemed necessary to reduce parking demand.
D. Reductions and Common Parking. Where there has been a reduction in required parking, all resulting spaces
must be available for common use and not exclusively assigned to any individual use. In residential and mixed-
use projects, required residential parking may be reserved, but commercial parking must be made available for
guests or overflow from residences.
E. Off-Site Parking. The Director may, by approving a Director’s Action (Chapter 17.108), allow some or all of the
required parking to be located on a site different from the use. Such off-site parking shall be within a zone where
the use is allowed or conditionally allowed, or within an office, commercial or manufacturing zone. It shall be within
300 hundred feet of the use and shall not be separated from the use by any feature that would make pedestrian
access inconvenient or hazardous. The site on which the parking is located shall be owned, leased, or otherwise
controlled by the party controlling the use.
17.72.060 – Nonconforming Parking.
For additions or changes in use for existing uses or structures that do not meet current parking standards, the following
standards shall apply.
A. Nonresidential Additions and Reconstruction. When expansion of floor area creates an increase of 10 percent
or more in the number of required onsite parking spaces in an existing nonresidential building, additional onsite
parking shall be provided for such addition and not for the entire building or site. Additional parking spaces are not
required for the reconstruction of an existing building when there is no increase in floor area.
B. Residential Additions. At least one legally conforming space shall be provided for each existing unit, in addition
to all parking required for the addition itself, unless otherwise exempted for an approved Accessory Dwelling Unit
or through an approved parking reduction, as authorized by Section 17.72.050 (Parking Reductions).
C. Use Changes. Changes in use that increase the total parking demand from existing legal uses that are
nonconforming because they do not meet current parking requirements may be allowed so long as the number
of spaces equal to the difference between the number required by the previous use and the number required by
the new use is provided, in addition to all spaces already provided for the previous use. The existing parking shall
be maintained. If the number of existing parking spaces is greater than the requirements for such use, the number
of spaces in excess of the prescribed minimum may be counted toward meeting the parking requirements for the
addition, enlargement, or change in use. A change in occupancy is not considered a change in use unless the new
occupant is in a different use classification than the former occupant.
17.72.070 – Bicycle Parking Standards.
A. Applicability.
1. The provisions of this Section shall apply to:
a. New multi-unit residential developments, non-residential developments, and community and institutional
facilities.
b. Existing nonresidential developments that involve a change in use. A change in occupancy is not
considered a change in use unless the new occupant is in a different use classification than the former
occupant.

The provisions of this Chapter apply to all zones in the City, except as otherwise specified.
17.76.030 – Front Yard Paving
No more than 40 percent of any residential front yard (see definition of “front yard” in Section 17.158.016 – F
Definitions), not to exceed 26 feet in width, may be covered by concrete or other impervious material, including
driveways, patio areas, walkways, and other landscape features.
17.76.040 – Front Yard Parking
A. Purpose and Application.
1. The purpose of these regulations is to preserve the residential character of streetscapes in the City’s
neighborhoods. The expansion of parking in front yard (see definition of “front yard” in Article 9) areas off
driveways interferes with the pattern of building masses and open areas within neighborhoods, creates vehicle
clutter, and results in excessive vehicle parking, which has the effect of creating small parking lots in front
yard areas that are intended to remain as open areas within neighborhoods.
2. These regulations apply to vehicle parking within the front yard areas as defined in in Section 17.158.016 – F
Definitions and shown in Figure 3-15: Front Yard, including the street side yard on corner lots. No person shall
stop, park, or leave standing any vehicle, whether attended or unattended, unless consistent with the

Chapter 17.78 Flood Damage Prevention
Sections:
17.78.010 – Statutory Authorization, Findings of Fact, Purpose, and Methods
17.78.020 – Definitions
17.78.030 – General Provisions
17.78.040 – Administration
17.78.050 – Provisions for Flood Hazard Reduction
17.78.060 – Variance Procedure for Floodplains
17.78.010 – Statutory Authorization, Findings of Fact, Purpose, and Methods
A. Statutory Authorization. The Legislature of the State has in Government Code Sections 65302, 65560, and
65800 conferred upon local governments the authority to adopt regulations designed to promote the public health,
safety, and general welfare of its citizenry. Therefore, the Council does hereby adopt these floodplain management
regulations.
B. Findings of Fact.
1. The flood hazard areas of the City are subject to periodic inundation, which results in loss of life and property,
health and safety hazards, disruption of commerce and governmental services, extraordinary public
expenditures for flood protection and relief, and impairment of the tax base, all of which adversely affect the
public health, safety, and general welfare.
2. These flood losses are caused by uses that are inadequately elevated, floodproofed, or protected from flood
damage. The cumulative effect of obstructions in areas of special flood hazards that increase flood heights
and velocities also contributes to flood losses.
C. Statement of Purpose. It is the purpose of this Chapter to promote the public health, safety, and general welfare,
and to minimize public and private losses due to flood conditions in specific areas by legally enforceable
regulations applied uniformly throughout the community to all publicly and privately-owned land within flood-prone,
mudslide (i.e., mudflow), and/or flood-related erosion areas. These regulations are designed to:
1. Protect human life and health;
2. Minimize expenditure of public money for costly flood control projects;
3. Minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the
expense of the general public;
4. Minimize prolonged business interruptions;
5. Minimize damage to public facilities and utilities such as water and gas mains; electric, telephone and sewer
lines; and streets and bridges located in areas of special flood hazard;
6. Help maintain a stable tax base by providing for the sound use and development of areas of special flood
hazard so as to minimize future blighted areas caused by flood damage;
7. Ensure that potential buyers are notified that property is in an area of special flood hazard; and
Ordinance No. 1650 (2018 Series)
EXHIBIT B
Article 3: Regulations Applicable to All Zones
3-74 September 2018
8. Ensure that those who occupy the areas of special flood hazard assume responsibility for their actions.
D. Methods of Reducing Flood Losses. To accomplish its purposes, this Chapter includes regulations to:
1. Restrict or prohibit uses that are dangerous to health, safety, and property due to water or erosion hazards,
or that result in damaging increases in erosion or flood heights or velocities;
2. Require that uses vulnerable to floods, including facilities that serve such uses, be protected against flood
damage at the time of initial construction;
3. Control the alteration of natural floodplains, stream channels, and natural protective barriers which help
accommodate or channel floodwaters;
4. Control filling, grading, dredging, and other development that may increase flood damage;
5. Prevent or regulate the construction of flood barriers that will unnaturally divert floodwaters or that may
increase flood hazards in other areas; and
6. These regulations take precedence over any less restrictive conflicting local laws, ordinances, and codes.
17.78.020 – Definitions
Words or phrases used in this Chapter shall be interpreted so as to give them the meaning they have in common usage
and to give this Chapter its most reasonable application, and as defined in Chapter 17.158 (General Definitions) under
“Floodplain Management Regulations.”
17.78.030 – General Provisions
A. Lands to Which This Chapter Applies. This Chapter shall apply to all areas of special flood hazards and where
specifically identified, XB zones, within the jurisdiction of the City.
B. Basis for Establishing the Areas of Special Flood Hazard. The areas of special flood hazard identified by the
Federal Emergency Management Agency (FEMA) in the “Flood Insurance Study (FIS) for the City of San Luis
Obispo, California in San Luis Obispo County” dated October 1978, with accompanying flood insurance rate maps
(FIRMs) and flood boundary and floodway maps (FBFMs), dated April 1979, and all subsequent amendments
and/or revisions, are hereby adopted by reference and declared to be a part of this Chapter. This FIS and attendant
mapping are the minimum areas of applicability of this Chapter and may be supplemented by studies for other
areas, including local experience and historical data which allow implementation of this Chapter and which are
recommended to the Council by the floodplain administrator to be included in the regulated area. The study,
FIRMs, and FBFMs are on file at the Department of Public Works, 919 Palm Street.
C. Compliance. No structure or land shall hereafter be constructed, located, extended, converted, or altered without
full compliance with the terms of this Chapter and other applicable regulations. Violation of the requirements
(including violations of conditions and safeguards) shall constitute a misdemeanor. Nothing here shall prevent the
Council from taking such lawful action as is necessary to prevent or remedy any violation.
D. Abrogation and Greater Restrictions. This Chapter is not intended to repeal, abrogate, or impair any existing
easements, covenants, or deed restrictions. However, where this Chapter and another ordinance, easement,
covenant, or deed restriction conflict or overlap, whichever imposes the more stringent restrictions shall prevail.
E. Interpretation. In the interpretation and application of this Chapter, all provisions shall be:
Ordinance No. 1650 (2018 Series)
EXHIBIT B
CITY OF SAN LUIS OBISPO
Title 17 – ZONING REGULATIONS
3-75 September 2018
1. Considered as minimum requirements;
2. Liberally construed in favor of the governing body; and
3. Deemed neither to limit nor repeal any other powers granted under State statutes.
F. Warning and Disclaimer of Liability. The degree of flood protection required by this Chapter is considered
reasonable for regulatory purposes and is based on scientific and engineering considerations. Larger floods can
and will occur on rare occasions. Flood heights may be increased by human-made or natural causes. This Chapter
does not imply that land outside the areas of special flood hazards or uses allowed within such areas will be free
from flooding or flood damages. This Chapter shall not create liability on the part of the Council, any officer or
employee thereof, the State, or the Federal Emergency Management Agency, for any flood damages that result
from reliance on this Chapter or any administrative decision lawfully made hereunder.
17.78.040 – Administration
A. Designation of the Floodplain Administrator. The Public Works Director or his/her designee is hereby appointed
to administer, implement, and enforce this Chapter by granting or denying development permits in accord with its
provisions.
B. Duties and Responsibilities of the Floodplain Administrator. The duties and responsibilities of the floodplain
administrator shall include but not be limited to the following:
1. Permit Review. Review all development permits to determine:
a. Permit requirements of this Chapter have been satisfied, including determination of substantial
improvement and substantial damage of existing structures;
b. The applicant was advised other local, State or Federal permits may be required;
c. The site is reasonably safe from flooding;
d. The proposed development does not adversely affect the carrying capacity of areas where base flood
elevations have been determined but a floodway has not been designated. This means that the
cumulative effect of the proposed development when combined with all other existing and anticipated
development will not increase the water surface elevation of the base flood more than one foot at any
point within the City;
e. If the proposed development is within a designated infill area, special floodplain management zone, or
the Mid-Higuera Specific Plan Area as defined by the Drainage Design Manual, that the more stringent
requirements of the manual have been met; and
f. All letters of map revision (LOMRs) for flood control projects are approved prior to the issuance of Building
permits. Building permits must not be issued based on conditional letters of map revision (CLOMRs).
Approved CLOMRs allow construction of the proposed flood control project and land preparation as
specified in the “start of construction” definition.
Ordinance No. 1650 (2018 Series)
EXHIBIT B
Article 3: Regulations Applicable to All Zones
3-76 September 2018
2. Development of Substantial Improvement and Substantial Damage Procedures.
a. Using FEMA publication FEMA 213, “Answers to Questions About Substantially Damaged Buildings,”
develop detailed procedures for identifying and administering requirements for substantial improvement
and substantial damage, to include defining “market value.”
b. Ensure procedures are coordinated with other departments/divisions and implemented by Community
Development Department staff.
3. Review, Use, and Development of Other Base Flood Data. When base flood elevation data has not been
provided in compliance with Section 17.78.030.B (Basis for Establishing the Areas of Special Flood Hazard),
the floodplain administrator shall obtain, review, and reasonably utilize any base flood elevation and floodway
data available from a Federal or State agency, or other source, in order to administer Section 17.78.050
(Provisions for Flood Hazard Reduction).
NOTE: A base flood elevation may be obtained using one of two methods from the FEMA publication, FEMA
265, “Managing Floodplain Development in Approximate Zone A Areas – A Guide for Obtaining and
Developing Base (100-Year) Flood Elevations” dated July 1995.
4. Notification of Other Agencies.
a. Alteration or Relocation of a Watercourse.
(1) Notify adjacent communities and the California Department of Water Resources prior to alteration or
relocation;
(2) Submit evidence of such notification to the Federal Emergency Management Agency; and
(3) Ensure that the flood carrying capacity within the altered or relocated portion of the watercourse is
maintained.
b. Base Flood Elevation Changes Due to Physical Alterations.
(1) Within six months of information becoming available or project completion, whichever comes first,
the floodplain administrator shall submit or ensure that the permit applicant submits technical or
scientific data to FEMA for a letter of map revision (LOMR).
(2) All LOMRs for flood control projects are approved prior to the issuance of building permits. Building
permits must not be issued based on conditional letters of map revision (CLOMRs). Approved
CLOMRs allow construction of the proposed flood control project and land preparation as specified
in the “start of construction” definition.
Such submissions are necessary so that upon confirmation of those physical changes affecting flooding
conditions, risk premium rates and floodplain management requirements are based on current data.
c. Changes in Corporate Boundaries. Notify FEMA in writing whenever the corporate boundaries have
been modified by annexation or other means and include a copy of a map of the community clearly
delineating the new corporate limits.
5. Documentation of Floodplain Development. Obtain and maintain for public inspection and make available
as needed the following:

F. Floodways. Since floodways are extremely hazardous areas due to the velocity of floodwaters that carry debris,
potential projectiles, and erosion potential, the following provisions apply:
1. Until a regulatory floodway is adopted, no new construction, substantial development, or other development,
including fill, shall be allowed within zones A1-30 and AE unless it is demonstrated that the cumulative effect
of the proposed development, when combined with all other development, will not increase the water surface
elevation of the base flood more than one foot at any point within the City.
2. If the proposed development is within a designated infill area, special floodplain management zone, or the
Mid-Higuera Specific Plan Area as defined by the Drainage Design Manual, the more stringent requirements
of the manual apply.
3. Within an adopted regulatory floodway, the City shall prohibit encroachments, including fill, new construction,
substantial improvements, and other development, unless certification by a registered civil engineer is
provided demonstrating that the proposed encroachment shall not result in any increase in flood levels during
the occurrence of the base flood discharge.

17.78.060 – Variance Procedure for Floodplains
A. Nature of Floodplain Variances. The issuance of a Variance is for floodplain management purposes only.
Insurance premium rates are determined by statute according to actuarial risk and will not be modified by the
granting of a Variance.
The Variance criteria contained in this Section of the Chapter are based on the general principle of zoning law that
Variances pertain to a piece of property and are not personal in nature. A Variance may be granted for a parcel of
property with physical characteristics so unusual that complying with the requirements of this Chapter would create
an exceptional hardship to the applicant or the surrounding property owners. The characteristics must be unique
to the property and not be shared by adjacent parcels. The unique characteristic must pertain to the land itself, not
to the structure, its inhabitants, or the property owners.
It is the duty of the Council to help protect its citizens from flooding. This need is so compelling and the implications
of the cost of insuring a structure built below flood level are so serious that variances from the flood elevation or
from other requirements in this Chapter are quite rare. The long-term goal of preventing and reducing flood loss
and damage can only be met if Variances are strictly limited. Therefore, the Variance guidelines provided in this
Chapter are more detailed and contain multiple provisions that must be met before a Variance can be properly
granted. The criteria are designed to screen out those situations in which alternatives other than a Variance are
more appropriate.
B. Conditions for Variances.
1. Generally, Variances may be issued for new construction, substantial improvement, and other proposed new
development to be erected on a lot of one-half acre or less in size contiguous to and surrounded by lots with
existing structures constructed below the base flood level, provided that the procedures of Sections 17.78.040
(Administration) and 17.78.050 (Provisions for Flood Hazard Reduction) of this Chapter have been fully
considered. As the lot size increases beyond one-half acre, the technical justification required for issuing the
Variance increases.
Ordinance No. 1650 (2018 Series)
EXHIBIT B
Article 3: Regulations Applicable to All Zones
3-84 September 2018
2. Variances may be issued for the repair or rehabilitation of “historic structures” (as defined in Chapter 158:
General Definitions, under Floodplain Management Regulations) upon a determination that the proposed
repair or rehabilitation will not preclude the structure’s continued designation as a historic structure and the
variance is the minimum necessary to preserve the historic character and design of the structure.
3. Variances shall not be issued within any mapped regulatory floodway if any increase in flood levels during the
base flood discharge would result.
4. Variances shall only be issued upon a de termination that the Variance is the “minimum necessary,”
considering the flood hazard, to afford relief. “Minimum necessary” means to afford relief with a minimum of
deviation from the requirements of this Chapter. For example, in the case of variances to an elevation
requirement, this means the Council need not grant permission for the applicant to build at grade, or even to
whatever elevation the applicant proposes, but only to that elevation which the Council believes will both
provide relief and preserve the integrity of this Chapter.
5. Any applicant to whom a Variance is granted shall be given written notice over the signature of the floodplain
administrator that:
a. The issuance of a Variance to construct a structure below the base flood level will result in increased
premium rates for flood insurance up to amounts as high as 25 dollars for 100 dollars of insurance
coverage; and
b. Such construction below the base flood level increases risks to life and property. It is recommended that
a copy of the notice shall be recorded by the floodplain administrator in the Office of the County of San
Luis Obispo recorder and shall be recorded in a manner so that it appears in the chain of title of the
affected parcel of land.
6. The floodplain administrator shall maintain a record of all Variance actions, including justification for his/her
issuance, and report such variances issued in its biennial report submitted to the Federal Emergency
Management Agency.
C. Authority to Grant Variances. Notwithstanding the provisions of Chapter 17.114 (Variances) of these Zoning
Regulations, the Council shall be responsible for conducting public hearings on Variances pertaining to the
provisions of this Chapter and for acting upon such Variance applications.
1. In acting upon requests for Variances, the Council shall consider all technical evaluations, all relevant factors
and standards specified in other Sections of this Chapter, and the:
a. Danger that materials may be swept onto other lands to the injury of others;
b. Danger of life and property due to flooding or erosion damage;
c. Susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on
the existing individual owner and future owners of the property;
d. Importance of the services provided by the proposed facility to the community;
e. Necessity to the facility of a waterfront location, where applicable;
f. Availability of alternative locations for the proposed use which are not subject to flooding or erosion
damage;
Ordinance No. 1650 (2018 Series)
EXHIBIT B

Title 17 – ZONING REGULATIONS

g. Compatibility of the proposed use with existing and anticipated development;
h. Relationship of the proposed use to the General Plan and floodplain management program for that area;
i. Safety of access to the property in time of flood for ordinary and emergency vehicles;
j. Expected heights, velocity, duration, rate of rise, and sediment transport of the floodwaters expected at
the site; and
k. Costs of providing governmental services during and after flood conditions, including maintenance and
repair of public utilities and facilities such as sewer, gas, electrical, and water system, and streets and
bridges.
2. Variances shall only be issued upon a:
a. Showing of good and sufficient cause;
b. Determination that failure to grant the variance would result in exceptional hardship to the applicant; and
c. Determination that the granting of a variance will not result in increased flood heights, additional threats
to public safety, or extraordinary public expense, create a public nuisance, cause fraud and victimization
of the public, or conflict with existing local laws or ordinances.
3. Variances may be issued for new construction, substantial improvement, and other proposed new
development necessary for the conduct of a functionally dependent use, provided that the provisions of
subsections C.1 through C.4 of this Section are satisfied and that the structure or other development is
protected by methods that minimize flood damages during the base flood and does not result in additional
threats to public safety and does not create a public nuisance.
4. Upon consideration of the factors of subsection B of this Section and the purposes of this Chapter, the Council
may attach such conditions to the granting of Variances as it deems necessary to further the purposes of this
Chapter.

administrative hearing officer, unless it is determined in the sole discretion of the administrative
hearing officer that a delay is in the public’s interest.

before the officer. The decision of the administrative hearing officer shall be based upon information

owner if not the same, and all other interested parties. New conditions of approval shall be made a part

The purpose of this Section is to provide two distinct procedures for reviewing land uses that may be appropriate in the
applicable zone, but whose effects on a site and its surroundings cannot be determined without discretionary review
and consideration of the site context. Use permits allow flexibility in providing for, regulating, or preventing particular
uses so they will be compatible with existing or desired conditions in their neighborhoods or zones. Use permit approval
is required for certain uses so that their detrimental effects can be reduced or avoided and potential conflicts in land
use can be prevented.
Where the term Use Permit is used in this Chapter, it shall mean and encompass Minor Use Permit and Conditional
Use Permit.
17.110.020 – Application Requirements
An application for a Minor Use Permit or Conditional Use Permit shall be filed and processed in compliance with Chapter
17.104 (Permit Application Filing and Processing). It is the responsibility of the applicant to provide evidence in support

The Reasonable Accommodation provisions allow for flexibility in the application of regulations and procedures to
ensure equal access to housing. The provisions set forth in this Chapter provide a procedure under which a disabled
person may request a reasonable accommodation in the application of zoning requirements. This Chapter is based on
requirements of the Federal and State fair housing laws and is designed to eliminate barriers to housing opportunities.
17.112.020 – Requests for Reasonable Accommodation

be made by a disabled person, his or her representative, or a developer or provider of housing for individuals with
disabilities. A request for Reasonable Accommodation may include a modification or exception to the siting,
development, and use of housing or housing related facilities that would eliminate regulatory barriers. A
Reasonable Accommodation cannot waive a requirement for a Minor Use Permit or Conditional Use Permit when
otherwise required or result in approval of uses otherwise prohibited by the City’s land use and Zoning Regulations.
B. Assistance. If an applicant needs assistance in making the request, the Planning Division will endeavor to provide
the assistance necessary to ensure that the process is available to the applicant.
C. Balancing Rights and Requirements. The City will attempt to balance the privacy rights and reasonable request
of an applicant for confidentiality with the land use requirements for notice and public hearing, factual findings, and
rights to appeal in the City’s request for information, considering an application, preparing written findings, and
maintaining records for a request for reasonable accommodation.
17.112.030 – Application Requirements
Whenever a request for Reasonable Accommodation is submitted for consideration, as a part of the application,
sufficient information shall be submitted to the Community Development Department to determine whether the
Reasonable Accommodation request complies with the provisions of this Chapter. In addition to the required Director’s
Action application checklist items, the application shall include the following:

shall comply with one or more of the following methods:
1. Construct the required number of affordable dwelling units, as specified in Table 2 of the Housing Element,
as adjusted by Table 2A of the Housing Element; or
2. Pay an in-lieu fee as described in Table 2, as adjusted by Table 2A. For development projects in which the
adjustment factor under Table 2A equals zero (“0”), the minimum adjustment factor shall be 0.25 (resulting in
a minimum in-lieu fee of 1.25 percent of the building valuation for development projects and commercial
developments in expansion areas, and 3.75 percent of building valuation for residential developments in
expansion areas); or
3. Dedicate real property for affordable housing; or
4. Provide for the rehabilitation of existing housing units that are vacant and in poor physical condition or are
otherwise uninhabitable; or

2. Multiply the total base Inclusionary Housing Requirement (either housing or in-lieu percentage) by the adjustment factor to
determine requirement. At least one enforceably restricted affordable unit is required per development of five or more units.
B. Affordable Housing Standards. Affordable dwelling units constructed must meet City affordable housing
standards and must be consistent with affordability policies in the General Plan Housing Element.
C. Concurrent Development. The required inclusionary units shall be constructed concurrently with market value
units unless the developer and the Director agree within an affordable housing agreement to an alternative
development schedule.
17.138.050 – Procedures
A. Fractional Numbers. In determining the number of dwellings that are required to be built pursuant to Table 2,
fractional units shall be rounded up to the next higher whole number unit.
B. Determining Adjustment Factor Using Project Density and Average Unit Size. To determine the adjustment
factor in Table 2A, project density shall be calculated by dividing the total number of density units proposed
(including density bonus where applicable) by the development project site’s net area. Average floor area shall be
calculated by dividing the total gross floor area of all dwellings (excluding garages) within the development project
by the total number of dwellings. Dedicated open space shall not be included in a site’s net area.
C. Mixed-Use Development Projects. For mixed-use development projects with five or more dwellings, the
inclusionary housing requirement is determined by: (1) using Table 2 to calculate the base inclusionary
requirement for the commercial use, and (2) using Table 2A to adjust the base requirement based on project
density and average unit size, as described in subsection (B) of this Section. For mixed-use development projects
with fewer than five dwellings, the base inclusionary housing requirement for the commercial use shall apply.
D. Timing. The inclusionary housing requirement shall be met prior to issuance of a certificate of occupancy for the
first unit in a building, or the first building in a complex to be constructed or remodeled; or for subdivisions, prior to
Final Map approval; or prior to building permit issuance, for projects for which a certificate of occupancy is not
issued; or as otherwise agreed to by the Director as part of tentative map, rezoning, Minor Use Permit, Conditional
Use Permit, or other development approval.
E. Affordable Housing Agreement. To meet the requirement, the developer may enter into an agreement with the
City, the Housing Authority of San Luis Obispo (HASLO), nonprofit housing provider, or other qualified housing
provider approved by the Director to construct, refurbish, convert, operate, and maintain the required affordable
housing. Such affordable housing agreements shall be to the approval of the Director and shall be in a form
approved by the City Attorney.

A. Payment of In-Lieu Fee. The developer may, at his or her discretion, choose to pay a fee to the City in lieu of
constructing affordable dwellings to meet this requirement.
B. Amount and Method of Payment. The dollar amount and method of payment of the in-lieu fee shall be as
described in Table 2 of Appendix N of the General Plan Housing Element, and where applicable, as adjusted by
Table 2A in Appendix N of the General Plan Housing Element, to the approval of the Director. For subdivisions in
which the construction valuation is not known, the Director shall estimate the average construction valuation based
on lot area, land value, and applicable City development standards. The developer shall use the estimated average
construction valuation to determine the amount of in-lieu fees.
C. Timing. In-lieu fees shall be paid prior to release of occupancy of the first dwelling within a residential development;
or for residential subdivisions to be built out by others, prior to final subdivision map approval; or prior to occupancy
for new commercial buildings or remodels; or prior to building permit issuance, for projects for which a certificate
of occupancy is not issued; or as otherwise provided by written agreement between the developer and City, to the
approval of the Director. For mixed-use developments, these regulations shall apply to whichever occupancy
release is first issued.
17.138.070 – Affordable Housing Fund Established
The City hereby establishes an Affordable Housing Fund. The fund shall be administered by the Finance Director and
shall be used exclusively to provide funding for the provision of affordable housing and for reasonable costs associated
with the development of affordable housing, at the discretion of the Council. In-lieu fees collected shall be deposited
into the Affordable Housing Fund, to the satisfaction of the Director of Finance.
17.138.080 – Real Property Dedication
A. Irrevocable Offer to Dedicate Real Property. At the discretion of the Council, an irrevocable offer to dedicate
real property equal or greater in value to the in-lieu fee which would otherwise be required may be offered to the
City, or to an affordable housing provider designated by the City, instead of providing the required number of
affordable dwellings or paying in-lieu fees. The City shall have the option of negotiating with the applicant regarding
dedications of properties with greater value that the in-lieu fee to achieve an equitable dedication. In considering
an offer to dedicate real property, the Council must find that the dedication of real property will provide equal or
greater public benefit than constructing affordable units or paying in-lieu fees, based on the following criteria and
additional criteria set forth in Government Code Section 65915(g)(2)(A-H):
1. Valuation of the land and/or improvements to be dedicated relative to other methods of meeting the
requirement;
2. Suitability of the land and/or improvements for housing, including General Plan conformity, size, shape,
topography, and location; and
3. Feasibility of developing affordable housing, including General Plan consistency, and availability of
infrastructure.
B. Real Property Valuation. The valuation of real property offered in lieu shall be determined by the Director, based
upon an appraisal made by a qualified appraiser mutually agreed to by the developer and the City. Costs
associated with the appraisal, title insurance and transfer, recordation, and related costs shall be borne by the
developer.

A. Eligibility for Incentives. The developer may be eligible to receive or to request development incentives in return
for constructing affordable housing in connection with a development project, pursuant to Chapter 17.140
(Affordable Housing Incentives), as part of a City planning application. Incentives or other forms of financial
assistance may be offered by the City to the extent that resources are available for this purpose and to the degree
that such incentives or assistance will help achieve the City’s housing goals.
B. Affordable Housing Agreement. Any incentives provided by the City, beyond those incentives to which a
developer may be automatically entitled to under Chapter 17.140 (Affordable Housing Incentives) shall require
Council approval and shall be set out in an affordable housing agreement. The form and content of such agreement
shall be to the approval of the City Attorney and the Director. Developers are further encouraged to utilize other
local, State or Federal assistance, when available, to meet the affordable housing standards.
17.138.100 – Project Application
A. Method of Application. An applicant/developer proposing a project for which affordable housing is required shall
submit a statement with the standard planning application, describing the inclusionary housing proposal. The

A. Submittal of an Affordable Housing Agreement. Applicants and developers for development projects subject
to this Chapter shall, as a condition of development approval, submit an affordable housing agreement on forms
provided by the City. The draft agreement shall be reviewed by the Director and City Attorney for compliance with
project approvals, City policies and standards, and applicable codes. Following approval and signing of the
agreement by the parties, the final agreement shall be recorded, and relevant terms and conditions shall be

Chapter 17.144: Residential Growth Management Regulations
Sections:
17.144.010 – Purpose and Justification
17.144.020 – Allocations
17.144.030 – Periodic City Council Review and Consideration of Revisions
17.144.010 – Purpose and Justification
A. The regulations codified in this Chapter are intended to assure that the rate of population growth will not exceed
the City’s ability to accommodate new residents and to provide municipal services consistent with the maximum
growth rates established in the General Plan. Also, these regulations are to assure that those projects which best
meet the City’s objectives for affordable housing, infill development, open space protection, and provision of public
facilities will be allowed to proceed with minimum delay.
B. San Luis Obispo is a charter city, empowered to make and enforce all laws concerning municipal affairs, subject
only to the limitations of the City charter and the constitution and laws of the State. Regulation of the rate of
residential development is a reasonable extension of municipal authority to plan overall development in furtherance
of the public health, safety, and general welfare.
C. According to the General Plan Land Use Element, the City should achieve a maximum annual average population
growth rate of one percent. The reserve of developable land within the City and the capacity of proposed
annexations could sustain growth rates which would exceed the objectives of the General Plan.
D. The growth rate policies of the General Plan reflect the City’s responsibility to accommodate a reasonable share
of expected State and regional growth.
E. To avoid further imbalance between the availability of jobs and of housing within the City, the General Plan also
manages expansion of growth-inducing activities. The burdens of growth management are not being placed solely
on the residential sector since it largely responds to demands caused by other sectors.
F. Considering the likely levels of housing demand and construction throughout the housing market area, nearly
coinciding with San Luis Obispo County, these regulations are not expected to affect the overall balance between
housing supply and demand in the market area. These regulations will not impede and may help meet the needs
of very low-, low-, and moderate-income households.
17.144.020 – Allocations
A. Each Specific Plan that authorizes residential development shall adopt a phasing schedule that allocates timing of
potential residential construction, including phasing of required improvements, consistent with the General Plan
and with these regulations.
B. The limitations on residential development established by these regulations apply to new residential construction
within certain areas that have been annexed to the City or that will be annexed to the City. Development in such
areas is subject to development plans or Specific Plans which shall contain provisions consistent with these
regulations.
C. Allocations shall be implemented by the timing of issuance of building permits.

Article 8: Housing-Related Regulations
8-24 September 2018
D. Dwellings affordable and enforceably restricted to residents with extremely low, very low, low, or moderate
incomes, as defined in the City’s General Plan Housing Element, new dwellings in the downtown core (C-D zone
as shown on the official zoning map), and legally established accessory dwelling units shall be exempt from these
regulations. Enforceably restricted shall mean dwellings that are subject to deed restrictions, development
agreements, or other legal mechanisms acceptable to the City to ensure long-term affordability, consistent with
City affordable housing standards. In expansion areas, the overall number of units built must conform to the City-
approved phasing plan.
E. It shall not be necessary to have dwellings allocated for a particular time interval or location to process and approve
applications for General Plan Amendment, Zoning Regulations Amendment, or other zoning action, Subdivision
application, or Architectural Review.
17.144.030 – Periodic City Council Review and Consideration of Revisions
The Community Development Department shall provide status updates to the Council concerning implementation of
these regulations, coordinated with the annual report on the General Plan. The status update will describe actual
construction levels and suggest if revisions are necessary to maintain the City’s one percent growth rate.
