UNIFORM DESIGN CRITERIA
General
The purpose of establishing these Standards is to help provide guidance for design of public facilities to better
ensure health, safety, and enhance community quality of life. These standards are not intended to be a
substitute for engineering knowledge, experience, or judgment. It is incumbent on the users of these standards
to exercise good judgment, and where needed, seek guidance from the appropriate professional.
This document must be used for new or reconstruction of existing facilities. Where deviation from these
standards is necessary, the designer must follow the Design Exception process outlined in this document.
These standards are not retroactive, existing facilities constructed prior to these standards are not required to
comply with these standards. New construction and reconstruction must comply with these standards unless
a design exception has been approved by the City. The applicant is responsible to either ensure facilities are
designed in compliance with these standards, or to secure design exception approval.
This document is supported by various publications that comprise the standard references for Public Works
projects. In event of conflict, it is the applicant’s responsibility to notify the City of that conflict and request
clarification. Without that notification, these standards will take precedence.
Reference documents include:
1. City of San Luis Obispo Engineering Standards
2. City of San Luis Obispo Standard Specifications
3. City of San Luis Obispo Community Design Standards
4. City of San Luis Obispo Fire Development Guide
5. American Water Works Association (AWWA) Standards
6. Caltrans State Standard Plans
7. Caltrans State Standard Specifications
8. San Luis Obispo County Public Improvement Standards

14. Caltrans DIB 82-05 Pedestrian Accessibility Guidelines for Highway Projects
15. National Association of City Transportation Officials (NACTO)
The applicant is responsible for obtaining any other required regulatory permits prior to the start of
construction. The Regulatory Agencies that may have jurisdiction over the applicant’s project include, but are
not limited to:
1. California Regional Water Quality Control Board (RWQCB)
2. California Department of Fish and Wildlife
3. U.S. Army Corps of Engineers (ACOE)
4. Air Pollution Control District (APCD)

Approval of any improvements plans for construction by the City does not exempt the
applicant/owner/contractor from compliance with regulations from other agencies and obtaining authority to
construct improvements from all required agencies.
1. Improvement Plans
Complete plans and specifications for all proposed public improvements that are not initiated by City of San
Luis Obispo must conform to these Standards. All improvement plans must be prepared and signed by a
registered Civil Engineer. Plans and specifications must be submitted to the City for review and approval prior
to the beginning of construction of any such improvements. Each utility company whose facilities are involved
must sign the original plans indicating they have reviewed and approved the plans. Construction may not begin
until the plans are signed by the City, and all submittals required have been provided to the City.
1.1 Preparation of Plans
1.1.1 Plan Review Procedure
A. Plan Check Intake at First Submittal
The Project Engineer must schedule an “intake” appointment, at which time the City will determine whether
the application package is complete. Checklists for various types of submittals are available on the City’s web
site www.slocity.org. Incomplete application packages or plans not conforming to the normal standards of
quality and neatness will be rejected. Project approval may be subject to public utility review and approval. It
is the responsibility of the Applicant to submit directly to those companies.
B. Plan Revisions
The applicant shall address all plan check comments or redlines prior to resubmittal. The Applicant must
provide a plan check response memo outlining the response to the plan check comments. In addition, the
applicant shall bubble or delta and number any changes made to the plans not associated with the plan check
comments. Failure to supply the required plan check response memo or denote separate plan changes will
result in rejection of plans at resubmittal.
When all corrections have been made to the satisfaction of the City, the Applicant must submit original signed,
sealed and dated drawings for approval. Plans are not approved until the City signifies approval by signature
on the title sheet of the original drawings. Construction is not authorized until the plans are approved and a
construction permits have been issued by the City.
Plan revision must be approved by the City prior to being constructed. The Applicant must submit a plan
addendum that clearly shows the desired change, and if needed, a request for a variance from City Standards.
C. Phased Improvements
Where the submitted improvement plans cover only a portion of the ultimate development, the plans
submitted must be accompanied by the approved overall tentative plan. The tentative plan must demonstrate
that the phased improvements are compatible with future phases.

1.1.2 Plan and Profile Layout
All plans must be prepared on:
1. Mylar;
2. Vellum;
3. Bond; or
4. Approved equal
Measuring 24" x 36" (ARCH D). Plans prepared for minor projects that do not require design professionals may
be submitted on letter or tabloid size bond paper. Appropriate plan scales are:
Horizontal Vertical
1-inch=20-feet 1-inch=2-feet or 1-inch=4-feet
1-inch=30-feet 1-inch=3-feet or 1-inch=6-feet
1-inch=40-feet 1-inch=4-feet or 1-inch=8-feet
The scale may be varied in rough terrain upon approval of the City.
A. Earthwork
If any grading is proposed outside the roadway prism, a grading plan must be submitted with the other required
improvement plans. Finished grading must be depicted by contour lines, spot elevations, or by “top/toe”
indications, as determined appropriate by the City. The grading plan must include a reference to the project
soils report, including its title, date and author. In addition, the applicant shall provide the City with proof of
an easement or right of entry when grading occurs on private property. The City may request a slope easement
for the offsite improvement.
B. Retaining Walls
For any proposed retaining walls, a separate sheet must be provided which depicts the elevation view and
typical section for each wall. The applicant shall provide appropriate easements for walls located on private
property. Walls on private property for new improvements shall be maintained by the private landowner,
maintenance association or homeowner’s association.
C. Roadway Improvements
Roadway plan and profile sheets must be of appropriate scale to clearly show the proposed plan layout, along
with existing and proposed profiles of all roadways. The boundaries of lots fronting on the roadway, drainage
easements, utility easements, slope easements, section lines and corners, land grant lines and temporary
construction easements must be shown on all roadway improvement sheets, including proper dimensions.
Each roadway plan and profile sheet must include the typical roadway section. The computed curve data for
all centerline curves must be shown on the plans.

3.1 Design Standards
3.1.1 General
All roadway cross sections must generally conform with adopted Specific Plans and the Circulation Element of
the General Plan, as modified by City direction specific to the area, and circumstances of development.
The design of a subdivision street system must result from an evaluation of topographical conditions, the traffic
generated by the types and numbers of planned uses, and the purpose of each street. Street systems should
be built to naturally encourage walking, community, safety and environmental stewardship. The City supports
concepts such as Complete Streets, Green Streets, and Living Streets. Special approvals by the City Engineer will be
needed for alternative street widths and elements. Minimum clear and passable street widths will be as required
by the Fire Department.
A complete street is a street designed and built to accommodate all users of the roadway including:
1. Pedestrians
2. Bicyclists
3. transit riders
4. commercial vehicles
5. general motorists.
A complete street provides access for all users regardless of age or ability.
In sloping terrain, separate one-way travel lanes may be used to reduce cut and fill. Such one-way lanes must
have a minimum unobstructed width of twenty feet, a minimum paved width of fourteen feet, and a maximum
length of five hundred feet.

Commercial Collector Streets collect traffic from commercial areas and channel it to arterials.
Residential Collector Streets collect traffic from residential areas and channel it to arterials.
Residential Arterials are bordered by residential property where preservation of neighborhood character is as
important as providing for traffic flow and where speeds should be controlled.
Arterial Streets provide circulation between major activity centers and residential areas.
Parkway Arterials are arterial streets with landscaped medians and roadside areas, where the number of cross
streets is limited and direct access from fronting properties is discouraged.
Highway/Regional Routes connect the city with other parts of the county and are used by people traveling
throughout the county and state and are designated as primary traffic carriers. Segments of these routes
leading into San Luis Obispo should include landscaped medians and roadside areas to better define them as
community entryways.
Freeway is a regional route of significance where access is controlled.

1. Average Speed is the summation of the instantaneous or spot-measured speeds at a specific location
of vehicles divided by the number of vehicles observed.
2. Design Speed is used to determine the various geometric design features of a roadway. Design speed
is selected in accordance with these standards or as determined by the City.
3. 85th-Percentile Speed is based upon measured field data and is the speed at or below which 85 percent
of the motor vehicles travel.
4. Operating Speed is the speed at which a typical vehicle or the overall traffic operates. Operating speed
might be defined with speed values such as the average, pace, or 85th percentile speeds.
5. Pace is the 10-mph speed range representing the speeds of the largest percentage of vehicles in the
traffic stream.
6. Posted Speed is the speed determined following an engineering and traffic survey (CVC 627).
7. Prevailing Speed is the 85th percentile speed.
8. Running Speed is the average operating speed over a selected road segment. On a straight level road
segment, the running speed will typically equal the prevailing speed throughout the road segment. On
road segments with varying conditions such as a curving mountain road, the operating speed may vary
at different points along the segment. The running speed is typically determined by the measuring
average time to travel the full segment.
Roadway design speed for existing roadway must match existing 85th percentile vehicle speeds. Design speed
for new streets is shown below:

alternative controlled access to arterial and thoroughfare streets. Alley right-of-way and pavement width must
be a minimum of twenty feet. Where two alleys intersect, a paved area free of obstructions must be provided
for safe visibility and turning.
3.1.8 Access Management
Private access points shall be designed in accordance with the following principles:
1. Limit and consolidate direct access to streets when possible.
2. Address topographical and geometric limitations that may impact safety & operations
3. Minimize interference with through-traffic operations and accommodate adequate lane capacity for
on-site traffic conditions.
4. Promote uniformly and well-spaced full movement intersections to reduce travel delay and crash risk.
Secondary or more access points are provided based on necessity, where more than one access point
is required or indispensable to the property due to circumstances that cannot be sufficiently mitigated
by other means. There should be objective and factual evidence to justify and document necessity for
multiple access points.
A. Intersections & Driveways:
Intersections should be well spaced at uniform intervals to help support the smooth and safe flow of traffic.
New intersections should not be spaced where functional areas (Figure A-1) overlap. Intersections that would
otherwise require all-way stop control or signalization should be controlled by Roundabouts or Neighborhood
Traffic Circle. All-way stop or signal control may be used if a roundabout or traffic circle control is determined
to be not feasible or operate at unacceptable levels. One-half mile spacing is recommended for traffic signals
on major arterials.
New or modified driveways shall not be allowed within the functional area (Figure A-1) of adjacent signalized
intersections with approach speeds of 30 mph or higher. Driveways maybe placed within the functional area
when left turns are restricted or the intersection is controlled by a roundabout. New driveways on streets with
speeds of 30 mph or higher should be have minimum spacing per the table below. Where property frontage
length restricts attainment of minimum driveway spacing, driveways should be placed at the maximum spacing
feasible. Closely spaced driveways may require restriction of left turns or application of a shared driveway.

4.5 Off-Street Parking
4.5.1 General
Location and design must comply with the Community Design Guidelines.
A. Pavement Surfacing
Parking lots and driveways must be paved with an all-weather surface, such as asphaltic concrete (AC)
pavement or Portland cement concrete (PCC) pavement. The minimum thickness of pavement must be as
specified in these standards. Base material must be compacted to a minimum of 95 percent. Compaction test
reports must be submitted to the Community Development Department for verification of proper compaction.
All motorcycle spaces within parking lots must be PCC pavement. If surfacing is allowed within the dripline of
existing trees, porous pavement surfaces must be used if approved or required by the City Arborist.
Alternative Permanent Paving: The Community Development Director may approve alternatives to AC or PCC
paving surfaces on private property. The Director may approve such alternative paving to achieve aesthetic
and environmental objectives, such as:
1. improved appearance,
2. increased water percolation,
3. reduced erosion and runoff,
4. increased aeration and water for tree roots,
5. reduced glare,
6. increased area available for landscaping
upon finding that the alternative paving will provide public aesthetic or environmental benefits, and is equal
to or better than AC or PCC paving in terms of:
1. public safety,
2. performance,
3. strength,
4. quality
5. durability
Examples of permanent alternative paving surfaces include, but are not limited to:
1. interlocking pavers,
2. eco-block,
3. porous AC paving,
4. cobblestone,
5. or other equivalent material as determined by the Community Development Director.
Alternative paving materials, when installed per manufacturer's specifications, must provide a suitable, all-
weather, load-bearing surface to support passenger cars and light-duty trucks. Alternative paving surfaces for
driveways or parking lots serving large commercial vehicles or fire trucks must be designed to accommodate a
maximum vehicle weight of 45,000 lbs. Alternative paving materials over City utility easements will not be

F. Parking Lot Maintenance
It is the duty of the property owner to maintain and repair the parking lot and related improvements in accordance
with the above standards and any other conditions imposed at the time of approval. If the Community
Development Department finds that the lot needs maintenance or repair, to ensure public safety and welfare, the
City may pursue enforcement under the authorities of the Municipal Code.
G. Loading Zones
Off-street loading zones must be a minimum of 12 feet wide and 25 feet long. Loading zones must be designed so
that trucks parking in them will not encroach onto the public right-of-way or into required parking spaces or
driveways. Loading spaces designed for large trucks must have appropriately larger access to allow maneuvering
without encroaching into landscape areas. Loading zones or areas may not encroach into fire lanes. Loading zones
(spaces) must be provided in accordance with the city's zoning regulations (refer to sections 17.46.020 and
17.48.010). Additional loading zones may be required by the Community Development Department or Fire
Department.

1. Side slope: 4:1 or 3:1 maximum with a minimum 12-inch-wide shoulder (2% slope toward facility)
adjacent to pedestrian use or curb.
2. Longitudinal slope: Maximum 6% longitudinal slope of bottom. Erosion and movement of soil and
mulch intensifies with increased longitudinal slope, minimize longitudinal slope. Stair stepping planters
on a slope to provide flat bottomed cells separated by check dam/weir overflows can provide more
storage and infiltration than a sloped facility.
3. Grades on opposite sides within a facility should be similar to optimize ponding across the entire
basin/cell.
C. Infrastructure
1. Inlet curb cut design selection should be based on application considerations:
a. Sloped sided or flat/planter facility
b. Curb and gutter adjacent to facility or separated by pedestrian sidewalk
2. Sidewalk edge type selection should be based on application considerations:
a. New or retrofit
b. Sloped sided or flat/planter
3. Sidewalk Curb: flat/planter requires 4” min. height curb adjacent to sidewalk for pedestrian safety.
Provide 4 to 6-inch-wide sidewalk curb notch when sidewalk drains to planter. Provide as many
notches as required to convey flow.
4. Energy dissipation: provide aggregate splash pads at inlets per inlet details. Provide 6” depth, 3" – 6"
rounded, washed cobble. For sloped sided facilities where inlet flow velocity is high, extend cobble
into facility, but avoid excessive or decorative use.
5. Overflow structure: Provide overflow structure or connect to approved discharge point.
D. Soil, Aggregate and Mulch
1. Aggregate layer: Where an aggregate layer is included in the design use Caltrans Class 2 Permeable.
Caltrans Class 2 Permeable does not require an aggregate filter course between the aggregate storage
layer and the bioretention soil media above. When Caltrans Class 2 Permeable is not available,
substitute Caltrans Class 3 Permeable. Class 3 Permeable requires an overlying 3” deep layer of ¾”
(No. 4) open graded aggregate (between Class 3 and bioretention soil media above). Use a minimum
depth of 12 inches.
2. Bioretention Soil Media (BSM): use Bay Area Stormwater Management Agencies Association (BASMAA)
Specification of Soils for Biotreatment or Bioretention Facilities (Attachment L). Provide pre-mixed
BSM, do not mix onsite. Provide a minimum of 24 inches of BSM depth. Where aggregate layer is used
and trees are specified, replace aggregate with increased BSM depth in tree planting locations.
3. Filter fabric - do not use fabric between BSM and aggregate layer
4. Provide mulch depth of 2 to 3 inches. Mulch use optional below ponding high water mark. Do not
apply mulch in ponding zone just prior to or during rainy season. Mulch non-floating mulch.

7. Wastewater
7.1 Design Standards
7.1.1 Quantity of Flow
Design flow criteria are summarized as follows (for newly constructed mains only – the Utilities Department will
provide data for older mains):
Domestic Sewage Generation Factors
Average dry-weather flow (ADWF):
Single Family Residential 150 gpd/EDU
Multi-Family Residential 105 gpd/EDU
Industrial / Manufacturing 54 gpd/k-sqft gross floor area
Business Park 54 gpd/k-sqft gross floor area
Commercial 60 gpd/k-sqft gross floor area
Motel / Hotel 70 gpd/room
Peak dry-weather flow (PDWF): ADWF x Peaking Factor
Reductions in peak flows occur because of storage in the system and diversification of development. The following
peaking factor must be used to obtain peak dry-weather flows:
Residential Peaking Factor = 2.6*(Q^-0.10)
Where Q is the cumulative average dry weather flow in the conveyance system calculated in million gallons per
day (MGD). Example: PF=2.6*(5.4MGD^-0.10) equals a peaking factor of 2.19.
Curves may be permitted if pipe deflection is limited to manufacturer's recommendations, with a minimum radius
of 100 feet, and the curves are only in one plane (either horizontal or vertical) between adjacent manholes. Sewer
mains and laterals must be located as shown in Engineering Standards 6010, 6110, 6140 and 6810.
Clearance between waterlines and other fluid pipelines must comply with California Code of Regulations Title 22,

normal operating conditions. Top of smaller pipe must be no lower than top of larger pipe(s).
7.1.3 Pipe
A. General
Sewer main size must be determined by designing for flowing half-full, considering the flow generated by the
development, the ultimate upstream development, and existing infiltration. New sewer systems shall be provided
with pipe materials that eliminate infiltration, and reduce the potential for root intrusion.
Minimum sewer main size is 8-inches diameter; except a 6-inch minimum size main may be allowed for the last
run which ends in a manhole and cannot be later extended to serve other properties. Laterals must be sized to be
adequate (4 inch minimum) for maximum allowable density on each specific lot.
Pipe material must be fused HDPE unless otherwise required for special conditions such as bridge crossings.
B. Laterals
Sanitary sewer laterals must be stubbed to the front property line of each lot. All facilities for the transmission
of sewage from each of the lots to the nearest adequate point of connection to the City’s sewer system must
be installed as acceptable to the City Engineer. Sewer services are not required for lots which will be in
perpetual open space use. The requirement for a sewer lateral may be waived upon a finding by the City that
an alternative waste disposal system, which will provide a level of protection for public health and natural
resources at least equivalent to public sewer, will be installed and maintained.

B. Agency Permits
All needed regulatory permits must be obtained by the developer prior to starting any work covered by or
impacted by those permit(s). The developer must keep these permits current. Copies of the permit
documentation must be kept on site for review by the City. Issuance of an encroachment permit or other
permits by the City does not relieve the developer from obtaining these permits.
C. Encroachment Permit
After approval of the improvement plans and prior to starting any work within the City right-of-way, the
Developer must obtain an encroachment permit from the City. Copies of the encroachment permit must be
kept on site for review by the City or other agency representatives.
12.2 During Construction
12.2.1 Inspection by Engineer of Work
The Engineer of Work has is responsibility for inspection during the construction of all improvements that are
regulated by these Standards. The Engineer of Work, at a minimum, must inspect the following milestones
during construction, and provide a written inspection report to the City:
1. Concrete form work
2. Hot Mix Asphalt paving operations
3. Initiating the placement of the roadway base course
4. Substantial completion of roadway base placement and compaction
5. Substantial completion of roadway subgrade excavation/fill placement
6. Trench bedding and compaction
Other required inspections may be determined necessary by the City.
12.2.2 Workplace and Worksite Conduct
1. It is expected that developers and their contractors will promote a businesslike workplace (including
work sites) that assures courteous treatment for workers, fellow contractors, City employees, and the
public. Harassment or discrimination based on race, religion, national origin, marital status, disability,
age, sex or sexual orientation is not to be tolerated.
2. It is expected that the developer and contractors will promote good relations with the neighbors and
public affected by a project. This typically requires regulating construction activity to minimize impacts
to the neighborhood caused by noise, dust, construction debris, and traffic disruption. When access
or traffic will be delayed, advanced notification must be provided to the affected neighbors as well as
to local emergency responders.
3. It is incumbent on the contractor to control the work site and provide a safe working environment.
Contractor must require employees to wear appropriate personal protective equipment while on the
work site.
4. It is incumbent on the contractor to control the work site and ensure all erosion control measures,
traffic control devices are in place and properly maintained. The work site must also be kept in clean
and orderly.

monoform system, and the concrete collar shall be poured to provide the joint between the manhole frame and the grade ring stack.
Inside of rings shall be grouted with non-shrink grout to obtain a smooth surface free from gaps, holes and sharp edges. 2" clearance
applies to the low side of the frame. Clearance may be greater on the high side as dictated by the street grades and as directed by the
City Engineer. Use 6" concrete reducing rings in cases where existing manhole opening must be reduced to accommodate the new
frame and cover.
GENERAL NOTES:
A.Completely remove existing concrete collar prior to pouring new concrete collar. The diameter of the new collar shall be equal to the
existing collar or the minimum diameter specified in the above detail, whichever is larger.
B.Concrete shall be Class 2 concrete, troweled to street grade, and allowed to cure for 24 hours prior to any traffic use. Class 1 concrete
with 2% non-corrosive polar set may be required to allow expedited traffic use following 4 hour cure time.
C.Depth and radius dimensions shown apply to similar covers that are not shown.
D.When a roadway is overlaid with asphalt concrete, the contractor may use extension rings to adjust utility covers to the new surface
elevation. When extension rings are used to adjust grade, a preformed thermoplastic ring shall be applied around the perimeter of the
concrete. Extension ring shall be compatible with the existing cover. Thermoplastic ring width shall be a minimum of 6 inches.
E.Utility frame and cover shall be installed so that cover does not rock or rattle and is flush with adjacent surface.

Page 1
CRITERIA FOR THE SEPARATION OF WATER MAINS AND SANITARY SEWERS
NEW FACILITIES SEPARATION STANDARDS
New water mains and sewer lines must comply with most recent version of the California Code of Regulations
Section 64572 Title 22 Chapter 16.
1. Parallel Construction: The horizontal distance between pressure water mains and sewer must be at least
10 feet.
2. Perpendicular Construction (Crossing): Pressure water main must be at least 12 inches above sanitary
sewer lines where these lines cross.
3. Separation distance is measured from the nearest edge of the facilities.
4. Water mains and sewer lines must not be installed in the same trench.
EXCEPTIONS TO BASIC SEPARATION STANDARDS
When local conditions or existing facilities create a situation where there is no alternative but to install water
mains or sewer lines at a distance less than that required by the new facilities separation standards. In such
cases, alternative construction criteria must be followed as allowed in the Department of Health Services
Memorandum for Guidance Criteria for separation of water mains and non-potable pipelines.
ALTERNATIVE CRITERIA FOR CONSTRUCTION
The construction criteria for sewer lines or water mains where the Basic Separation Standards cannot be attained
are shown in Figures 1 and 2, Engineering Standard 6140. There are two situations encountered:
Case 1 -- New sewer line – new or existing water main.
Case 2 -- New water main -- existing sewer line.
For Case 1, the alternate construction criteria apply to the sewer line.
For Case 2, the alternate construction criteria may apply to either or both the water main and sewer line.
The construction criteria apply to the house laterals that cross above a pressure water main. House laterals
crossing below water main must have 4 inches of separation between water main and lateral.
CONSIDERATION OF RECYCLED WATER
Recycled water mains must be treated as sewer mains when considering their separation from potable water.
Recycled water mains must be treated as potable water mains when considering their separation from sewers.

GENERAL NOTES:
A.Total thickness of cover depends on R-value of basement soil as well as the Traffic Index assigned to the street.
All street sections shall be designed according to the Cal Trans method which is outlined in Chapter 600 of the Cal
Trans Highway Design Manual.
B.Pavement design shall be based on the traffic indexes shown below, which are based on a 20-year design life for
reconstruction or resurfaced streets, and a 50-year design life for new streets.
C.For paving in new subdivisions that is placed prior to construction of buildings, the pavement will be subjected to
traffic and wear associated with the on-site construction. In order to accommodate this additional usage, the A.C.
thickness shall be increased from that which is derived from Cal Trans method by either:
a.12" if total section is placed prior to building construction (unphased).
b.1" if pavement construction is phased.
The pavement section for street widening shall be based on the T.I. of a reconstructed street, and the thickness of the new
A.C. shall at a minimum match the thickness of the existing A.C.
New streets and road widening where asphalt surface is increased 10 feet or more shall be fog sealed no more than 60
days prior to request for final acceptance by the City. New streets shall be fog sealed the entire length and width of asphalt
surface. Road widening shall be fog sealed to the centerline of the widened roadway for the entire widened length, at a
minimum.
Variation of these design standards may be approved by the City Engineer to meet individual circumstances.
A street shall be designed as a new street when existing utilities have been constructed within the past 5 years.

PLAN DEVELOPMENT STANDARDS
REQUIRED USE OF STANDARD
Use of this standard is required for use on: All projects, including mapping, that are City funded All projects which will be turned over to the City for adoption or maintenance All Final (Tract) and Parcel Maps (this standard supplements provisions of the
Subdivision Map Act)
DATUM
Drawings and maps shall be set into real world coordinates and elevations using the City’s horizontal and vertical control networks. The Datum used shall be referenced on the cover
sheet.
Plans based on information furnished by the City, from old plans or survey data, shall include references to the City Plan number, file number, field book number, etc.
Any new bench marks and monuments should be shown on the plans with the associated
coordinates and / or elevation.
Horizontal Control
The City has established a horizontal control network relative to the California Coordinate System Zone Five, which is defined in Section 8801 through 8819 of the California Public
Resources Code. For all projects and maps, two different exterior points or corners shall be
tied to at least two different points of the City's horizontal control network for direct import into the Geographic Information System (GIS) database and AutoCAD. The Horizontal Control Network is available from the Public Works Department.
Vertical Control
The City has established a vertical control network. All projects shall be tied to the nearest bench mark elevation. The Bench Mark System is available from the Public Works Department.
Grading Plans
Finish and existing grades shall be shown by use of contours on grading plans. Where grades are too flat for contours to be meaningful, grades shall be called out showing existing and final elevations for a number of points reasonable to represent critical grades and drainage. All contours and elevations shall reflect current City Datum.
UNITS OF MEASUREMENT
All project plans and maps shall be prepared in English units unless written permission has been obtained from the Director of Public Works
Appendix F
DRAWINGS
Software
Drawings are to be produced using AutoCAD or Civil 3D compatible with the current version in use by the City. Other programs which produce an AutoCAD drawing may be acceptable; however, if there are incompatibility problems, the project will be rejected until compatible files are produced.
Drawing Sheets
Drawing sheet borders shall be fully contained on a 22” x 34” sheet. The border should reduce 50% to fit completely on an 11” x 17” sheet. Drawings shall be plotted on sheets no larger than 24” x 36”. The City recommends use of the electronic files available from the City. These files have already been sized for ease of reduction, contain blocks, typical
layers, line types and color assignments.
In lieu of the profile sheet, grids generated by design software may be substituted. Improvement Plans submitted to the City shall have the standard title block shown in the
plan and cover sheets available electronically from the City for privately funded projects.
Map Sheets
Map sheet shall be 18” x 26” with a border 1 inch inside the edge of the sheet in accordance with the Map Act.
Naming Conventions
The following naming convention shall be used to identify the drawings:
For projects developed in ACAD 2000 or higher version: Complete the drawing in model space and use the layout tabs for sheet layout in paper space:
City Specification No. (Tract No.,MS No., Parcel Map No.)_01.dwg Cover Sheet Drawing City Specification No. (Tract No.,MS No., Parcel Map No.)_00.dwg Model and Layout Drawing Ex: Tract 452_01.dwg
If desired, the cover sheet may be incorporated in the main drawing using the _00 extension for the entire project. For projects developed in earlier versions (without layout tabs): City Specification No. (Tract No., MS No., Parcel Map No.)_00.dwg for model space drawing
City Specification No. (Tract No., MS No., Parcel Map No.)_01.dwg for Cover Sheet City Specification No. (Tract No., MS No., Parcel Map No.)_02.dwg for Sheet 2 (XXXX_00.dwg is to be bound to the sheet drawing.) Continue numbering (xxxx_xx.dwg) for required number of sheets
If drawing sheets are modified during construction and new sheets are printed, they shall use the sheet number and a letter following to designate the change. Ex. Tract 400_05A.dwg
Appendix F
The preferred practice is for page numbers to be sequential for the entire plan set. Where
the project contains multiple disciplines, landscaping, electrical, etc., the City will accept multiple drawings named as shown above. Ex: Tract 452_E00 for the electrical drawing
Tract 452_M00 for the mechanical drawing
Tract 452_L00 for the landscape plan, etc.
Model Space and Paper Space
Drawings are to be generated in model space and then plotted with borders in paper space. Refer to the software manual for additional information.
Drawings shall be done in full scale (one drawing unit = 1 foot,) actual dimensions in model space. All borders and titles shall be done in paper space. Scaling of model space drawing to fit paper size shall be done using viewports and model view scaling.
General Drawing Content
Drawings shall contain the following minimum elements: Title Block North Arrow Creek & Street Names Vicinity Map Bar Scale Centerline Monuments Dimensions Date Lot lines & numbers
Stationing Legends Tract Name & number
Bench Marks Easements Bearings, radii, etc. Topography Elevations Existing Utilites Datum Reference Trees & Driplines Engineering Standard with numbers referenced
Tree diameter shall be accurately represented. Drip lines shall be shown for any tree not permitted for removal. Grading, utility and landscape plans shall not be combined on the same sheet. Curves shall
show radius, delta, curve length and control for BC and EC to allow construction.
External References (xrefs)
Xrefs shall be bound to or inserted in the drawing in which they are needed for printing. Xrefs used during design, but not displayed for printing shall be detached.
User Coordinate System (UCS)
When rotation is necessary for plotting, a UCS shall be used in lieu of rotating the drawing out of the original orientation.
Stationing
Stationing shall be north to south or west to east running left to right on the paper. Beginning stationing shall be tied to an existing centerline intersection. Coordinates for the beginning
station and ending station shall be shown on the plans. Alignments and stationing should be on a street centerline when work will occur within a street. Profiles can be generated either on the centerline or offset, as long as their location is clearly defined on the profile.
Appendix F
On City funded projects (Capital Improvement Program) stationing for different streets in the
same project shall not have duplicate stationing numbers. Ex: A Street Waterline – Sta 1+00 to Sta 3+58, B Street Paving – Sta 4+00 to Sta 6+97
North Arrows and Bar Scales
North arrows and bar scales shall be inserted in model space such that a north arrow and
bar scale appear in each plan view when plotted. Blocks shall not be so ornate as to obscure their content.
Scales
Plotting scale shall be appropriate to the type of project allowing adequate detail clarity. Bar
scales shall be inserted in model space such that a bar scale appears in each plan view
when plotted. Scale should appear in the lower right hand corner whenever possible. For sheets containing both plan and profile information, a ratio of the Horizontal to the Vertical scale shall be shown in the title block.
Example of typical scales:
Utility, Grading and Street Improvements Plan 1” = 20’ Paving and Traffic Control Plan 1” = 100’ Signal Plan 1” = 10’ or 1” = 20’
Blocks
Blocks shall be created on layer 0 at scale 1:1 with line type and color by layer.
Layering
Drawings shall provide separate layers for the various items shown in the drawings using appropriate layer prefixes to group related layers. See Appendix B for additional information. Where allowed by the program, layer “state” or settings for printing shall be saved and
named print_sheet#. Civil 3D defaults may be used for layer naming. Alignment names should be selected to mimic the layering conventions set forth in the appendix to the degree possible, and layer names shall be generated using the alignment prefix option such that all layers related to the
alignment begin with the alignment name.
Color and Line Types
All colors and line types shall be By Layer. Layer colors and line pen designations shall be those shown in the City prototype drawings. See Appendix C for additional information.
Pen weights shall be those designated in the plot file for those colors associated with standard layers. Polylines shall not have an assigned width, but rather be given weight through pen designation. Generally, abandoned and existing facilities are shown with a fine line weight or at half tone,
with abandoned facilities using hidden or dashed line types, in lieu of the standard
Appendix F
continuous line type. New facilities are shown in bolder line types. Line scale shall be set so
that line types, other than continuous, repeat frequently enough to be clearly differentiated.
Dimensions
Dimensions shall have characteristics by layer. The dimensions shall appear on the text layer or a new layer specifically for dimensions. Dimensioning text shall be per this standard.
Text
Accepted fonts are limited to those native to the Windows operating system or furnished
with AutoCAD or Civil 3D. Where new text styles are created, they should have the same name as the font used for that style. The use of AutoCAD’s predefined “Standard” text style, which defaults to the txt font type, is not encouraged.
Text shall always be on a separate layer. Line labels shall be above the line and not cut into
the line.
Plotting
Whenever possible, use the plot file furnished by the City. If this is not possible, save a plot file for the project and submit it with the drawing files. Plot file shall be named using the
same naming convention as for drawings, with the default file name extension.
RECORD DRAWINGS
When construction is complete, a record drawing of the project shall be completed as set forth below. Record drawing layers may be added as need to provide proper printing for
each sheet. Save the file using the naming convention as for drawings followed by R.
Ex: Tract 452_E00R Record drawing for electrical sheets
Create a new layer and name it Record_Drawing
Set color to 200 and line type to continuous. Colors 201 & 202 may also be used as needed to address different line weights.
Record all record drawing information on the Record Drawing layer
Each sheet is to be “stamped” to note record drawings have been completed for that sheet. If no changes were made, a note to that effect is to be included adjacent to the stamp.
Each sheet is to be numbered with an “R” after the sheet number. Ex. 2R of 13
Set all pen colors but pen 200, 201, and 202 to color 253 or use the City standard plot file for record drawings.
Complete plotting of record drawing set
SUBMITTALS
Drawing files must be completely compatible with the current City AutoCAD standard program. Bond used for submittals shall be a minimum of 20lb.
City funded projects
All electronic files shall be submitted to the City. For projects developed using design software, the entire project folder shall be submitted, including all the sub folders with
Appendix F
drawings and supporting data. The electronic folder shall be submitted in the configuration
generated by the software. Drawing file shall be purged of all unused layers, text, etc.
Written specifications shall also be submitted in electronic format. Submit one original, stamped and signed, ink on bond, set of plans and one original
stamped and signed set of specifications along with the electronic files prior to the start of
construction. Submittal shall also include a complete Acrobat Adobe file bid package (Specifications and Plans.) Record drawings are to be submitted within 4 weeks of completion of construction and shall
include a signed scan (.tif) or adobe file in addition to the drawing files.
Files shall be submitted to the designated Project Manager for Capital Improvement projects.
Privately funded projects
Submit the electronic drawing files (.dwg) and any associated plot files along with one
original, stamped and signed, ink on bond, set of plans prior to the start of construction or Map recording. Record drawings are to be submitted within 4 weeks of completion of construction and prior

Guideline Specifications for Nursery Tree Quality
Selecting Quality Nursery Stock
A committee comprised of municipal arborists, urban foresters, nurserymen, U.C. Coopera-
tive Extension horticultural advisors, landscape architects, non–profit tree groups, horticul-
tural consultants, etc., developed the attached specifications to ensure high quality landscape
trees. After more than a year of work, they succeeded in drafting a document entitled Specifi-
cation Guidelines for Container–grown Trees for California. This document will be published
and the guidelines promoted throughout the nursery and landscape industry. Its intent is to
help landscape professionals develop their own comprehensive and detailed specifications to
ensure that they obtain high quality container–grown nursery trees. The document is also
intended to help nursery professionals in their efforts to improve the quality of trees grown in
California. These specifications can be modified for specific simulations.
The following people worked on the Guideline Specifications for Nursery Tree Quality:

Appendix I
Guideline Specifications for Nursery Tree Quality
I. PROPER IDENTIFICATION
All trees shall be true to name as ordered or shown on the planting
plans and shall be labeled individually or in groups by species and
cultivar (where appropriate).
II. COMPLIANCE
All trees shall comply with federal and state laws and regulations
requiring inspection for plant disease, pests and weeds. Inspection
certificates required by law shall accompany each shipment of plants.
Clearance from the County Agricultural Commissioner, if required,
shall be obtained before planting trees originating outside the county
in which they are to be planted. Even though trees may conform to
county, state, and federal laws, the buyer may impose additional
requirements.Illustration by Edward F. Gilman, Professor,Environmental Horticulture Department, IFAS,
University of Florida.
III. TREE CHARACTERISTICS AT THE TIME OF SALE OR DELIVERY
A. TREE HEALTH
As typical for the species/cultivar, trees shall be healthy and vigorous, as indicated by an
inspection for the following:
1. Trees shall be relatively free of pests (insects, pathogens, nematodes or other injurious
organisms).
2. An inspection of the crown, trunk, and roots shall find the following characteristics:
a. Crown Form: The form or shape of the crown is typical for a young specimen of the spe-
cies/cultivar. The crown is not significantly deformed by wind, pruning practices, pests or
other factors.
b. Leaves: The size, color and appearance of leaves are typical for the time of year and stage
of growth of the species/cultivar. Leaves are not stunted, misshapen, tattered, discolored
(chlorotic or necrotic) or otherwise atypical.
c. Branches: Shoot growth (length and diameter) throughout the crown is typical for the age/
size of the species/cultivar. Trees do not have dead, diseased, broken, distorted or other
serious branch injuries.
d. Trunk: The tree trunk should be fairly straight, vertical and free of wounds (except prop-
erly–made pruning cuts), sunburned areas, conks (fungal fruiting bodies), wood cracks,
bleeding areas, signs of boring insects, galls, cankers/lesions and girdling ties.
e. Tree height and trunk diameter are typical for the age, species/cultivar and container size.
f. Roots: The root system is free of injury from biotic (insects, pathogens, etc.) and abiotic
agents (herbicide toxicity, salt injury, excess irrigation, etc.). Root distribution is uniform
throughout the soil mix or growth media and growth is typical for the species/cultivar.
Appendix I
B. CROWN
1. Central Leader: Trees shall have a single, relatively straight central leader and tapered
trunk, free of codominant stems and vigorous, upright branches that compete with the central
leader. If the original leader has been headed, a new leader at least ½ (one–half) the diameter
of the original leader shall be present.
Maintaining a single, centeral leader is preferable.
Heading and retaining a leader is acceptable.
Heading without retaining a leader is unacceptable.
Appendix I
2. Main Branches (scaffolds): Branches should be distributed radially around and vertically
along the trunk, forming a generally symmetrical crown typical for the species.
a) Main branches, for the most part, shall be well spaced.
preferable unacceptable preferable unacceptable
b) Branch diameter shall be no greater than 2/3 (two thirds) the diameter of the trunk,
measured 1" (one inch) above the branch.
preferable unacceptablepreferable unacceptable
c) The attachment of scaffold branches shall be free of included bark.
preferable unacceptable preferable unacceptable
Appendix I
3. Temporary branches: Temporary branches should be present along the lower trunk,
particularly for trees less than 1–1/2" (one and one–half inches) in trunk diameter. They
should be no greater than 3/8" (three–eighths inch) in diameter. Heading of temporary
branches is often necessary to limit their growth.
Good Not as Good
C. TRUNK
1. Trunk diameter and taper shall be sufficient so that the tree will remain vertical without
the support of a nursery stake.
2. The trunk shall be free of wounds (except properly–made pruning cuts), sunburned areas,
conks (fungal fruiting–bodies), wood cracks, bleeding areas, signs of boring insects, galls,
cankers and/or lesions.
3. Trunk diameter at 6" (six inches) above the soil surface shall be within the diameter range
shown for each container size below:
Container Size Trunk Diameter (inches)
# 5 (gallon) ....................... 0.5" to 0.75"
# 15 (gallon) .................... 0.75" to 1.5"
24 inch box ....................... 1.5" to 2.5"
# 15 (gallon) ............0.75" to 1.5"
24 inch box .............1.5" to 2.5"
36 inch box .............2.5" to 3.5"
48 inch box .............3.5" to 4.5"
Appendix I
D. ROOTS
1. The trunk, root collar (root crown) and large roots shall be free of circling and/or kinked
roots. Soil removal near the root collar may be necessary to inspect for circling and/or kinked
roots.
2. The tree shall be well rooted in the soil mix. When the container is removed, the rootball
shall remain intact. When the trunk is carefully lifted both the trunk and root system shall move
as one.
preferable
preferable unacceptable
3. The upper–most roots or root collar shall be within 1" (one inch) above or below
the soil surface.
preferable unacceptable
unacceptable
Appendix I
4. The rootball periphery should be free of large circling and bottom–matted roots. The
acceptable diameter of circling peripheral roots depends on species and size of rootball. The
maximum acceptable size should be indicated for the species (if necessary).
preferable unacceptable
E. MOISTURE STATUS
At time of inspection and delivery, the rootball shall be moist throughout. The crown shall
show no signs of moisture stress as indicated by wilted, shriveled or dead leaves or branch
dieback. The roots shall show no signs of excess soil moisture conditions as indicated by poor
root growth, root discoloration, distortion, death or foul odor.
V. INSPECTION
The buyer reserves the right to reject trees that do not meet specifications as set forth
in these guidelines or as specified by the buyer. If a particular defect or substandard
element or characteristic can be easily corrected, appropriate remedies shall be re-
quired. If destructive inspection of a rootball(s) is to be done, the buyer and seller
should have a prior agreement as to the time and place of inspection, minimum num-
ber of trees or percentage of a species or cultivar to be inspected and financial respon-
sibility for the inspected trees.
DELIVERY
The buyer should stipulate how many days prior to delivery that notification is needed.
Appendix I
GLOSSARY:
Codominant – Two or more vigorous and upright branches of relatively equal
size that originate from a common point, usually where the leader has been lost
or removed.
Crown – The aboveground part of the tree including the trunk.
Cultivar – A named plant selection from which identical or nearly identical
plants can be produced, usually by vegetative propagation or cloning.
Girdling root – A root that partially or entirely encircles the trunk and/or
buttress roots, which could restrict growth and downward movement of photo-
synthate and/or water and nutrients up.
Included bark – Bark embedded within the crotch between a branch and the
trunk or between two or more stems that prevents the formation of a normal
branch bark ridge. This often occurs in branches with narrow-angled attach-
ments or branches resulting from the loss of the leader. Such attachments are
weakly attached and subject to splitting out.
Kinked root – A primary root(s), which is sharply bent, causing a restriction
to water, nutrient, and photosynthate movement. Kinked roots may compro-
mise the structural stability of root systems.
Leader – The dominant stem which usually develops into the main trunk.
Photosynthate – Pertains to sugar and other carbohydrates that are produced
by the foliage during photosynthesis, an energy trapping process.
Root collar – The flared area at the base of a tree where the roots and trunk
merge. Also referred to as the "root crown" or "root flare".
Shall – Used to denote a practice that is mandatory.
Should – Used to denote a practice that is recommended.
Scaffold branches – Large, main branches that form the main structure of the
tree.
Temporary branch – A small branch that is retained temporarily along the
lower trunk of young trees. Temporary branches provide photosynthate to
increase trunk caliper and taper and help protect it from sunburn damage and
mechanical injury. Such branches should be kept small and gradually removed
as the trunk develops.
Trunk – The main stem or axis of a tree that is supported and nourished by the roots
and to which branches are attached.

QUALITY ASSURANCE PROGRAM
City of San Luis Obispo
Quality Assurance Program for Construction
1. GENERAL
The City of San Luis Obispo’s (City) Quality Assurance Program (QAP) has been developed by the
City to provide guidelines for testing of construction materials and assurance that the materials
incorporated into the construction projects are in conformance with the contract specifications. The
City’s QAP is updated approximately every five years to address changes to project specifications,
materials, and updates to the testing methods.
The City’s QAP will be used on all City projects off of the National Highway System including those
projects which receive federal funds. Regardless of project funding, City projects on the National
Highway System will use the QAP developed by the California Department of Transportation
(Caltrans).
2. ACCEPTANCE TESTING PROGRAM
City staff will typically perform inspection duties on a project. Those duties include verification of
compliance with the project’s plans, special provisions, City Standard Specifications and Engineering
Standards, and State Standard Specifications and Standard Plans. When testing of construction materials
is required, a materials testing consultant is typically used to perform acceptance testing on City projects.
2.1 Materials Laboratory
The consultant’s materials laboratory is required to be under the responsibility of a California-registered
Civil Engineer with experience in sampling, inspection and testing of construction materials. The
laboratory shall certify the results of all tests performed by its personnel under the Engineer’s
supervision. The laboratory is required to contain certified test equipment capable of performing the tests
conforming to the provisions of this Quality Assurance Program (QAP).
The materials laboratory is required to provide documentation that it complies with the following
procedures:
• Correlation Testing Program – The materials laboratory shall be a participant in one or
more of the following testing programs:
a. AASHTO Materials Reference Laboratory
b. Cement and Concrete Reference Laboratory
c. Caltrans’ Reference Samples Program
• Certification of Personnel – The materials laboratory shall employ personnel who are certified
by one or more of the following:
a. Caltrans District Materials Engineer and/or Caltrans METS IA Representative
b. Nationally recognized non-Caltrans organizations such as the American Concrete Institute,
National Institute of Certification of Engineering Technologies, etc.
c. Other recognized organizations approved by the State of California and/or Recognized by
local governments or private associations.
Appendix J
• Laboratory and Testing Equipment – The materials laboratory shall only use laboratory and
testing equipment that is in good working order. All such equipment shall be calibrated at least
once each year. All testing equipment must be calibrated by impartial means using devices of
accuracy traceable to the National Institute of Standards and Technology. A decal shall be
firmly affixed to each piece of equipment showing the date of the last calibration. Testing
equipment calibration decals shall be checked as part of the Independent Assurance Program
(IAP).
2.2 Acceptance Testing
Acceptance Testing will be performed by certified materials testing personnel utilizing an accredited
materials laboratory. The certifications and accreditations shall be specific to the tests being performed.
The test results will be used to ensure that all materials incorporated into the project are in compliance
with the contract specifications.
The City requires compliance with its Standard Specifications on all projects located within the City
right-of-way, or on City-owned property.
Testing must be in accordance with the Caltrans test methods whenever applicable. When Caltrans test
methods are not feasible for a certain test, a national recognized standard (i.e., AASHTO, ASTM, etc.)
test method may be utilized. Testing frequencies are to be in accordance with the contract specifications.
If not specified in the contract specifications, samples shall be taken at the frequencies specified in the
following table:
Material Test for:Sample Frequency

Note: All tests must be performed at a minimum of one test per project, unless otherwise addressed in the
in the “Acceptance of Minor Quantities of Materials” sections of this QAP.
The following are time periods for reporting material test results to the Resident Engineer:
• When the aggregate is sampled at material plants, test results for Sieve Analysis, Sand Equivalent and
Cleanness Value should be submitted to the Resident Engineer within 24 hours after sampling.
• When materials are sampled at the job site, test results for compaction and maximum density should
be submitted to the Resident Engineer within 24 hours after sampling.
• When soils and aggregates are sampled at the job site:
Appendix J
1. Test results for Sieve Analysis, Sand Equivalent and Cleanness Value should be submitted to the
Resident Engineer within 72 hours after sampling.
2. Test results for “R” Value and asphalt concrete extraction should be submitted to the Resident
Engineer within 96 hours after sampling.
When sampling products such as Portland Cement Concrete (PCC), cement-treated base (CTB), hot mix
asphalt (HMA), and other such materials; the time of such sampling will be varied with respect to the
time of the day insofar as possible, in order to avoid a predictable sampling routine. The reporting of
Acceptance Testing results, if not performed by the Resident Engineer’s staff, shall be done on an
expedited basis such as by email or telephone.
