Prepared By: Barbara Lynch, City Engineer
Matt Horn, Assistant City Engineer
SUBJECT: 2014 STANDARD SPECIFICATIONS AND ENGINEERING STANDARDS
RECOMMENDATION
Adopt a resolution approving the following actions:
1. Adopt the 2014 City Standard Specifications and Engineering Standards and rescind the
previous resolution.
2. Authorize the release of projects currently in design under the 2010 City Standard
Specifications on a case by case basis.
DISCUSSION
Background
The Public Works Department maintains a set of Standard Specifications and a set of Engineering
Standards under the responsibilities of the City Engineer. These two documents set forth the general
guidelines and requirements for design and construction for City projects, including private
development work within existing or future right of way or City property. The purpose of these
standards is to set a level of quality and consistency in construction. These two things, combined
with active inspection, increase the longevity and function of public improvements and reduce long-
term maintenance costs. In addition, the specifications provide contractual language to guide the
behavior and relationship between contractors and the City during construction activities. Adoption
of these standards by the Council assists in protecting the City from litigation through laws relating
to design immunity.
The City Standard Specifications work in conjunction with the State of California Department of
Transportation Standard Specifications. The City references the State book with modifications
where appropriate to meet City needs. The State book covers many standard contract issues and
legal requirements such as labor laws, payment and liability. The City specifications focus on
construction specifications for work the State does not typically handle such as water, wastewater,
and park facilities. The Engineering Standards are pictorial construction details showing how
facilities are put together. These are largely specific to City construction with only a few references
to using typical State construction details.
The Capital Improvement Program Engineering section of Public Works updates the City Standard
Specifications and the Engineering Standards on a periodic basis to reflect changes in construction
practices, materials, and to add clarifications. During the year, design or construction activities

typically reveal areas that would benefit from modifications within the documents. Suggested
improvements are kept on file and the standard or specification is revised as appropriate during the
next update. These changes are generally intended to add clarification, close loopholes, or update
standards to be consistent with new technology, current construction practices, and City adopted
policies.
2014 Revisions
Unlike past updates, the revisions for the 2014 standards have been significant. This is not a result
of actual changed requirements as much as it is a result of the complete rewriting of the State
Standard Specifications on which the City Specifications are based. The second item which has
resulted in significant changes to the standards is the adoption by the Central Coast Regional Water
Quality Control Board (CCWB) of Post Construction Requirements (formerly referred to as
Hydromodification).
1. State Standard Rewrite
Typically the State makes revisions to its Standard Specifications and designates those in a “track”
mode, showing a vertical line in the margin to allow for ease of locating changes. From these cues,
the City then updates its own Standard Specifications to reflect the acceptance or deletion of those
changes, while adding revisions based on specific City needs. As part of the 2010 State Standard
Specification Caltrans took on the conversion of the text to “plain language” in response to
Government Code Section 6219, and Presidential Executive Order of 1998 requiring this.
The State took the opportunity of the rewriting to implement some restructuring, adding sections,
and completely reorganizing the sections. In response, the City “pulled apart” its specifications,
realigned them to the new sections and organization, used plain language wherever possible, and
reconstructed a new set of City Standard Specifications. The State is currently starting work on its
2015 Specifications, but indicates changes will be consistent with the 2010 book, and not a
reversion to the previous style and organization. Staff anticipates a simpler revision coming
forward to Council in 2016.
2. Post Construction Requirements
The City is mandated under federal regulations relating to clean water to have and enforce a
stormwater program. The City is enrolled under the state’s General Stormwater Permit through the
CCWB, the regional arm of the State Water Resources Control Board. The State Water Resources
Control Board is tasked with the enforcement of the Clean Water Act by the federal Environmental
Protection Agency.
Example – Plain Language:
Written numbers and notes on a
drawing govern over graphics.

In February 2008, while the City was still going through a process to enroll under the stormwater
permit, it was notified, along with all other local agencies, of the CCWB intent to implement
hydromodification management as part of the enrollment. This added new requirements to the
standards under which the City had been preparing its Stormwater Management Plan. An update of
this change was provided to the Council on December 2, 2008. There was considerable response
from agencies to the CCWB, and ultimately, the CCWB initiated the “Joint Effort” with agencies in
the region to cooperatively develop the language to address hydromodification. This saved
individual agencies from developing hydromodification management programs on their own, at an
estimated cost of $400,000 each. On January 19, 2010, the Council reviewed the hydromodification
proposal and concurred with the recommendation to have the City participate in the Joint Effort.
The results of the Joint Effort are the “Post Construction Stormwater Management Requirements for
Development Projects in the Central Coast Region” (PCR) adopted by the CCWB. A review of
these requirements was provided to the Council on August 7, 2012. The CCWB completed final
adoption of the new regulations in July 2013, including some revisions which reduce the severity of
the requirements. Implementation by the City is required by March 6, 2014. The Architectural
Review Commission received a presentation in August 2012 regarding hydromodification and
proposed minor revisions to the Community Design Guidelines maintained by the Community
Development Department. A presentation of the new requirements was also made to the Planning
Commission in May 2013.
The focus of the PCR is to maximize the infiltration of water back into the ground, minimizing
runoff and recharging ground water. This can be a challenge, particularly for high density
developments. The PCRs have some incentives to encourage dense development, but revisions
have also been made to the City’s Uniform Design Criteria for Streets, Drainage, Landscape, and
Subdivision Design Criteria and Improvement Standards, in the Engineering Standards, to allow
developers the maximum flexibility in meeting the PCRs. Some of these changes update the
Uniform Design Criteria to embrace more modern design concepts for complete streets, and
encouraging alternative transportation modes. The Uniform Design Criteria also requires the
compliance with the PCRs. These changes are the most significant of the changes made in this
update of the standards. Attachments 1 and 2 provide the draft changes and a final copy to better see
the changes. The work is the combined effort of the transportation, community development and
engineering staff.
3. Miscellaneous Other Changes
Of the miscellaneous other changes, the most significant are the switch to Light Emitting Diodes
(LED) as the standard for street light installations, and changes to pipeline replacement work. The
Utilities Department is requiring fused High Density Polyethylene pipe in order to provide a more
reliable system for the long term. Additional methods of pipe replacement that reduce surface
impacts, such as reaming and pipe bursting, have been included as well. Some projects have been
completed using these materials and methods under specific project Special Provisions, and they are
ready for inclusion in the standards.
Other minor revisions to the standards include revisions to sidewalk and cross-gutter slopes to
improve disabled access to the roadway. The new standards incorporate Caltrans’ revised curb
C4 - 3
2014 Standard Specifications and Engineering Standards Page 4
ramp design requirements. Additionally, sewer lateral requirements have been updated to require
glued joints in order to align with municipal code requirements.
Carryover Projects
A handful of projects are substantially complete with design using the City’s 2010 Engineering
Standards and Specifications (referenced to Caltrans 2006 standards). To minimize impacts to
project delivery, staff anticipates releasing these contracts for construction under the old standards
on a case-by-case basis. Wherever possible, those projects that are substantially complete will be
converted.
CONCURRENCES
The City Attorney provided review of key project closeout and claim handling language.
Modifications requested by the Utilities Department for water and wastewater facilities have been
incorporated.
FISCAL IMPACT
While the changes to Standard Specifications are significant, the impacts of those changes are
anticipated to have either minor or insignificant impact on the cost of construction or development.
This is because most of the change was format and presentation. Changes to pipe materials, light
fixtures and allowance of alternative construction methods is not anticipated to result in significant cost
impacts to construction or development.
The change to the Engineering Standard Uniform Design Criteria as it relates to Post Construction
Requirements is significant. The City and other agencies have worked with the CCWB to minimize
the impacts to the greatest extent possible, and the City is under obligation to adopt and enforce these
criteria. As reviewed with the Council and advisory bodies, there will be some challenges for larger
City and development projects.

UNIFORM DESIGN CRITERIA
For Development
Refer to the Community Design Standards and Fire Development Guide for additional information
and guidance.
A. STREETS
The design of a subdivision street system should result from an evaluation of topographical
conditions, the traffic likely to be generated by the types and numbers of planned uses, and the
purpose of each street. The street system must allow an acceptable pattern of lots (see Sections
17.36.150 through 17.36.230 of the City’s Municipal Code).
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.
Wet utilities should be placed within the roadway prism for maximum accessibility.
Geometrics:
All regional highways and arterial streets shall have cross sections generally conforming with
adopted Specific Plans and the Circulation Element, as modified by City direction specific to the area
and circumstances of development.
Minimum clear and passable street widths will be as required by the Fire Department.
All streets shall intersect other streets at right angles, and shall have at least 50 feet of centerline
tangent, as measured from the prolongation of the cross-street property line to the angle point or
beginning of curve. Roundabouts should be considered in lieu of traditional intersections where level of
service thresholds can be accomplished.
For cul-de-sacs and residential minors, “T” or three-way intersections are preferable to four-way
intersections. On these streets, intersections should be spaced at least one hundred fifty feet apart,
measured from centerline to centerline.
Block lengths for local and collector streets should be a minimum of 150 feet and a maximum of 600
feet. Block lengths for arterial streets should be a minimum of 600 feet. Street systems should be
networked to improve connectivity and reduce travel distances for alternative transportation.
The minimum outside corner radius is 10’ for local residential streets, with larger radii for commercial
or industrial areas where large vehicle use is frequent. Frequently used areas shall provide radii that
allow for a large vehicle to turn at an intersection without crossing the centerline into oncoming
traffic. Inside corners, such as on a street with a ninety degree turn, shall have a minimum radius of
20’ to allow for sweeping.
For collector and arterial streets, four-way intersections are preferable. On these streets,
intersections should be spaced at least six hundred feet apart.

Blocks on minor and collector streets should not be longer than one thousand two hundred feet,
unless topography and lower density of development make longer blocks desirable.
Collector, arterial and thoroughfare streets shall intersect at right angles and shall be straight at least
fifty feet from the intersection, measured from the cross-street property line, unless the City Engineer
approves an alternate design.
Streets with a regular cross section and no special provision for turn- around shall be provided at
the edges of a subdivision when the City determines they may be extended in the future.
Space for turning vehicles shall be provided at the ends of access courts (cul-de-sac)streets with no
outlet. A cul-de-sac The turning circle may include landscaping or parking within a central island so
long as space for turning and backing from driveways is provided. Design of terminus streets, such
as cul-de-sacs, shall be to the satisfaction of the City Fire Department and City Engineer . If the court
serves seven or more dwellings, a turning circle shall be provided with dimension equal to or greater
than those in the Engineering Standard 7020.
If the court serves six or fewer dwellings, a hammerhead or other arrangement may be approved by
the City Engineer and Fire Marshal.
Alleys may be required in industrial, commercial and multifamily residential subdivisions where
necessary to provide alternative, controlled access to arterial and thoroughfare streets. Alley right-of-
way and pavement width shall be a minimum of twenty feet. Where two alleys intersect, a paved
area free of obstructions shall be provided for safe visibility and turning.
Parkway areas which include trees shall be a minimum of 5 feet wide. Parkways created in existing
integral sidewalk areas will be handled on a case-by-case basis.
Grades and Cross Slope:
Street grades on other than arterials and thoroughfares, shall not exceed fifteen percent. Grades on
arterial streets and thoroughfares shall not exceed ten percent, unless the City Engineer approves a
steeper grade, which shall not exceed fifteen percent. The grade on switchbacks or curbs of less
than fifty-feet centerline radius shall not exceed five percent.
The minimum street grade shall be one percent, except that where topographical conditions do not
allow any feasible alternative, and with the approval of the City Engineer, grades not less than 0.3
percent may be allowed.
Design of street grades at intersections shall follow the principles indicated in the most current
edition of AASHTO manual "A Policy on Geometric Design of Highways and Streets."
In sloping terrain, separate one-way travel lanes may be used in order to reduce cut and fill. Such
one-way lanes shall have a minimum unobstructed width of twenty feet, a minimum paved width of
fourteen feet, and a maximum length of five hundred feet.
Where excavation or fill slopes extend beyond the street right-of-way, easements for the slopes may
be required by the City.

Cross slope shall be considered during street construction and rehabilitation design. Cross slope is
typically 2 percent but may range from 1.5 percent to 3 percent to accommodate terrain.
For streets where curbs roadway pavement edges are at different heights, a quarter crown point is
typical with the crown no more than 10 feet from the high side curb face.
The grade break at the gutter should not exceed 20 percent at a driveway to prevent vehicles from
dragging on the ground or sidewalk.
Streets designed with super elevation shall be designed in accordance with current California
Department of Transportation Highway Design Manual guidelines.
Slopes for crossings and access points shall meet accessibility requirements.
Pavement:
Pavement design shall follow the California Department of Transportation Highway Design Manual,
be based on a 20-year design life and the "R-value" of the subgrade material. New local streets
shall be designed for a 50-year life.
Pavement thickness shall be based on Traffic Indices shown in City Engineering Standard 7110.
Variations of the design standards and pavement materials may be approved by the City Engineer
to meet individual circumstances.
See also Section B and Engineering Standard 7110 for other requirements affecting street design.
Sidewalks and Bicycle Lanes:
Sidewalks are required on both sides and shall be designed and constructed per Engineering
Standards. Alternative surface materials may be approved on a case-by-case basis by the City
Engineer to facilitate infiltration; however, ADA access requirements must be met. Sidewalks must
slope to drainage facilities, either planting areas or gutters.
Standard minimum sidewalk width is 6 feet5 feet detached, 6 feet integral. Commercial sS idewalk
widths are 8, 10 and 12 feet for commercial development may be required up to 7 feet detached,
12 feet integral, depending on the location of the commercial development and anticipated
pedestrian traffic . In areas where these widths cannot be maintained, sidewalk shall have a
minimum of 5 feet clear width, including the curb top.
All sidewalks shall have a minimum thickness of 4 inches, and driveways shall have a minimum
thickness of 6 inches.
Integral curb, gutter and sidewalk shall be constructed without a cold joint between the curb and
the sidewalk.
Curb returns shall be designed to minimize overly steep grades of curbs through the returns, to the
satisfaction of the City Engineer. Generally, the grades of curb returns should not exceed the
grades of the adjacent streets, and should accommodate state standards forinclude accessible

curb ramps. Additional landing area may be needed at corners, outside the planned right-of-way, to
accommodate ramps.
Curb extensions may be required to restrict parking at intersections for visibility and to reduce
pedestrian crossing distances.
Provisions for bike facilities shall be in accordance with the adopted Bicycle Transportation Plan.
The City may approve alternatives to sidewalks or bicycle lanes immediately adjacentincorporated
into the roadway section. Such alternate routes shall be within a public right-of-way or public
easement and shall provide a level of access and pedestrian/cyclist safety equivalent to or better
than provided by conventional locations. Where alternative pedestrian paths or bicycle paths are
provided to the satisfaction of the City, the conventional sidewalks or bicycle lanes may be
eliminated. Where curbside parking is provided, there must be safe pedestrian access to it.
The alternative pedestrian path or bicycle paths shall be logically related to conventional sidewalks
or bike lanes in order to safely divert pedestrian/bicycle travel from roadway sections lacking
roadside walks or bike lanes.
The City may require improved walkways, in addition to sidewalks, through blocks more than nine
hundred feet long to provide access to parks or public facilities.
Any existing feature in the sidewalk that is of a special, unique, unusual, or historic nature, as
determined by the City, shall not be replaced, removed, or altered without specific approval of the
City Engineer.
Curb Ramps:
Curb ramps shall be installed at all intersections where sidewalks exist or are to be built at some
future date.
Curb ramps should be located in the most logical place to accommodate pedestrians crossings in
the crosswalk.
Curb ramps shall comply with the provisions and standards required by the City, State, and Federal
Government. Any deviation from standards requires a finding of unreasonable hardship by the City
Engineer signed design exception, approved by the City Engineer .
Mission Style Sidewalk District:
The following requirements apply to construction in the Mission Style Sidewalk District, which is
defined in Resolution No. 9114 (2000 Series). See map in appendix.
a. Mission Style Sidewalk, curb and gutter shall be constructed per City Engineering Standard

g.f. Any existing feature in the sidewalk that is of a special, unique, unusual, or historic nature,
as determined by the City, shall not be replaced, removed, or altered without specific
approval of the City Engineer.
Street Parking:
Parking is not allowed on regional highways and arterial streets. Parking on one or both sides is
allowed on all other street types. Where the proposed design allows parking in only certain areas,
parking pockets, extended gutter construction, or other methods of clearly defining legal parking, are
required.
Parking areas may be used for infiltration of stormwater where suited to the site conditions. Design
shall be such as to prevent damage to adjacent roadway sections from infiltration, to the satisfaction
of the City Engineer.
The City may approve alternatives to the provision of curbside parking along cul-de-sacs, residential
minors, residential collectors and commercial/industrial minors. Alternate parking may be allowed for
any subdivision where the City determines the resulting street design is adequate for the type and
extent of planned uses. Curbside parking reductions are It is encouraged in hillside developments to
reduce where the amount of grading , may be reduced in comparison with conventional street
sections and in all other areas to reduce run-off volumes and pavement maintenance costs.
If curbside parking is not provided, alternate parking equivalent to one space for each twenty-five
feet of frontage shall be provided. Such alternate parking shall be provided within a public right-of-
way, or on lots adjacent to the street, with convenient access to the street on-site may be required
depending on the development type and anticipated parking demand.
Access Restrictions:
Reserve strips of land to control access from adjoining property to public streets may be required by
the City. Such reserve strips shall be at least one foot wide and shall be deeded in fee to the City.
They shall be shown and clearly labeled on the final map. Access restrictions may also be
incorporated by note on the map.

B. DRAINAGE AND EROSION CONTROL
General:
All new development or redevelopment shall comply with the criteria and standards set forth in the
Waterways Management Plan – Drainage Design Manual, applicable area specific plans, and the
Post-Construction Stormwater Management Requirements for Development Projects in the Central
Coast Region, adopted by the Central Coast Regional Water Quality Control Board, and included
in the appendices. Where requirements conflict, the stricter shall apply.
Stormwater Control Plan and Operation and Maintenance Plan are required prior to final approvals.
Streets:
Cross gutters are only allowed at intersections. Cross gutters are not allowed to cross
highway/regional routes ,or arterial streets or bus routes. Cross gutters will only be allowed to
cross a collector street at intersections where the collector street traffic is required to stop or yield.
Stormwater management facilities may be built into the right-of-way, including medians, traffic
circles, and parkways, subject to approval by the City Engineer. Where stormwater management
features are built into the right-of-way, water must be managed to prevent damage to the roadway
structural integrity.
Water Quality:
Where a new development project results in the installation of 5,000 ft2 or more of impervious drive
surfaces or when a redevelopment project results in the addition of impervious drive surfaces
resulting in 5,000 ft2 or more of drive surfaces; all stormwater runoff from drive surfaces shall be
treated in accordance with the Best Management Practices (BMP) published in the most current
addition of the California Stormwater Quality Association’s Best Management Practice Handbook.
Drive surfaces is defined as the parking stalls, loading bays, trash areas and drive aisles.

UNIFORM DESIGN CRITERIA
For New and Redevelopment
Refer to the Community Design Standards and Fire Development Guide for additional information
and guidance.
A. STREETS
The design of a subdivision street system should result from an evaluation of topographical
conditions, the traffic likely to be generated by the types and numbers of planned uses, and the
purpose of each street. The street system must allow an acceptable pattern of lots (see Sections
17.36.150 through 17.36.230 of the City’s Municipal Code).
Street systems should be built to naturally encourage walkability, 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.
Wet utilities should be placed within the roadway prism for maximum accessibility.
Geometrics:
All regional highways and arterial streets shall have cross sections generally conforming with
adopted Specific Plans and the Circulation Element, as modified by City direction specific to the area
and circumstances of development.
Minimum clear and passable street widths will be as required by the Fire Department.
All streets shall intersect other streets at right angles, and shall have at least 50 feet of centerline
tangent, as measured from the prolongation of the cross-street property line to the angle point or
beginning of curve. Roundabouts should be considered in lieu of traditional intersections where level of
service thresholds can be accomplished.
Block lengths for local and collector streets should be a minimum of 150 feet and a maximum of 600
feet. Block lengths for arterial streets should be a minimum of 600 feet. Street systems should be
networked to improve connectivity and reduce travel distances for alternative transportation.
The minimum outside corner radii is 10’ for local residential streets, with larger radii for commercial
or industrial areas where large vehicle use is frequent. Frequently used areas shall provide radii that
allow for a large vehicle to turn at an intersection without crossing the centerline into oncoming
traffic. Inside corners, such as on a street with a ninety degree turn, shall have a minimum radius of
20’ to allow for sweeping.
Streets with a regular cross section and no special provision for turn-around shall be provided at
the edges of a subdivision when the City determines they may be extended in the future.
Space for turning vehicles shall be provided at the ends of access streets with no outlet. A cul-de-
sac may include landscaping or parking within a central island so long as space for turning and

backing from driveways is provided. Design of terminus streets, such as cul-de-sacs, shall be to the
satisfaction of the City Fire Department and City Engineer.
Alleys may be required in industrial, commercial and residential subdivisions where necessary to
provide alternative, controlled access to arterial and thoroughfare streets. Alley right-of-way and
pavement width shall be a minimum of twenty feet. Where two alleys intersect, a paved area free of
obstructions shall be provided for safe visibility and turning.
Parkway areas which include trees shall be a minimum of 5 feet wide. Parkways created in existing
integral sidewalk areas will be handled on a case-by-case basis.
Grades and Cross Slope:
Street grades on other than arterials and thoroughfares, shall not exceed fifteen percent. Grades on
arterial streets and thoroughfares shall not exceed ten percent, unless the City Engineer approves a
steeper grade, which shall not exceed fifteen percent. The grade on switchbacks or curbs of less
than fifty-feet centerline radius shall not exceed five percent.
The minimum street grade shall be one percent, except that where topographical conditions do not
allow any feasible alternative, and with the approval of the City Engineer, grades not less than 0.3
percent may be allowed.
Design of street grades at intersections shall follow the principles indicated in the most current
edition of AASHTO manual "A Policy on Geometric Design of Highways and Streets."
In sloping terrain, separate one-way travel lanes may be used in order to reduce cut and fill. Such
one-way lanes shall have a minimum unobstructed width of twenty feet, a minimum paved width of
fourteen feet, and a maximum length of five hundred feet.
Where excavation or fill slopes extend beyond the street right-of-way, easements for the slopes may
be required by the City.
Cross slope shall be considered during street construction and rehabilitation design. Cross slope is
typically 2 percent but may range from 1.5 percent to 3 percent to accommodate terrain.
For streets where roadway pavement edges are at different heights, a quarter crown point is typical.
The grade break at the gutter should not exceed 20 percent at a driveway to prevent vehicles from
dragging on the ground or sidewalk.
Streets designed with super elevation shall be designed in accordance with current California
Department of Transportation Highway Design Manual guidelines.
Slopes for crossings and access points shall meet accessibility requirements.
Pavement:

Pavement design shall follow the California Department of Transportation Highway Design Manual,
be based on a 20-year design life and the "R-value" of the subgrade material. New local streets
shall be designed for a 50-year life.
Pavement thickness shall be based on Traffic Indices shown in City Engineering Standard 7110.
Variations of the design standards and pavement materials may be approved by the City Engineer
to meet individual circumstances.
See also Section B and Engineering Standard 7110 for other requirements affecting street design.
Sidewalks and Bicycle Lanes:
Sidewalks are required on both sides and shall be designed and constructed per Engineering
Standards. Alternative surface materials may be approved on a case-by-case basis by the City
Engineer to facilitate infiltration; however, ADA access requirements must be met. Sidewalks must
slope to drainage facilities, either planting areas or gutters.
Standard minimum sidewalk width is 5 feet detached, 6 feet integral. Sidewalk widths for
commercial development may be required up to 7 feet detached, 12 feet integral, depending on the
location of the commercial development and anticipated pedestrian traffic. In areas where these
widths cannot be maintained, sidewalk shall have a minimum of 5 feet clear width.
Integral curb, gutter and sidewalk shall be constructed without a cold joint between the curb and
the sidewalk.
Curb returns shall be designed to minimize overly steep grades of curbs through the returns, to the
satisfaction of the City Engineer. Generally, the grades of curb returns should not exceed the
grades of the adjacent streets, and include accessible curb ramps. Additional landing area may be
needed at corners, outside the planned right-of-way, to accommodate ramps.
Curb extensions may be required to restrict parking at intersections for visibility and to reduce
pedestrian crossing distances.
Provisions for bike facilities shall be in accordance with the adopted Bicycle Transportation Plan.
The City may approve alternatives to sidewalks or bicycle lanes incorporated into the roadway
section. Such alternate routes shall be within a public right-of-way or public easement and shall
provide a level of access and pedestrian/cyclist safety equivalent to or better than provided by
conventional locations. Where alternative pedestrian paths or bicycle paths are provided to the
satisfaction of the City, the conventional sidewalks or bicycle lanes may be eliminated. Where
curbside parking is provided, there must be safe pedestrian access to it.
The alternative pedestrian path or bicycle paths shall be logically related to conventional sidewalks
or bike lanes in order to safely divert pedestrian/bicycle travel from roadway sections lacking
roadside walks or bike lanes.
The City may require improved walkways, in addition to sidewalks, through blocks more than nine
hundred feet long to provide access to parks or public facilities.

Lot lines.
A. Lot lines should be at the top of slope banks.
B. Side lot lines should be perpendicular to the street on straight streets, or radial to the street on
curved streets, unless another angle would provide better building orientation as documented in the
submittal.
C. On corner lots, the lot lines adjacent to streets shall be rounded with a radius adequate to provide
for street improvements.
Flag lots (deep lot subdivision).
Flag lots may be approved for subdividing deep lots where development would not be feasible with
the installation of a standard street, either alone or in conjunction with neighboring properties, or
where justified by topographical conditions. Such subdivision shall conform to Subdivision
Regulations, Section 16.18.060 of the Municipal Code.
