INTRODUCTION
PURPOSE
The purpose of this Bicycle Plan is to improve bicycle transportation in Davis. This is an update
of the 2001 Draft Bikeway Plan in an effort to maintain a Bicycle Plan which is meaningful to
the city and which meets the requirements contained in Section 891.2 of the California Streets
and Highways Code.
SETTING
The City of Davis is located in the southern part of Yolo County, a predominantly agricultural
county in California's central valley. Davis is the largest urbanized area within Yolo County.
In 1906, The University of California, Berkeley established the State Agricultural Experiment
Station at Davis. The college became a general campus of the University of California System in
1959. Between 1950 and 1987, the average annual growth rate was 6.4 percent per year as the
urban population grew from under 5,000 to 48, 700. The 2005 in-city population of Davis is
approximately 64,259. Approximately 10,000 of the 30,000 UCD students reside within the city
limits and are included in the population figure.
Yolo County temperatures are generally mild in the winter and hot in the summer. October
through April is the rainy season, and accounts for approximately 90% of the area's annual
precipitation.
South Davis is separated from the rest of the City by Interstate Highway 80, which is the major
freeway serving the area. State Route 113 connects I-80 in Davis with the City of Woodland and
Interstate Highway 5 to the north.
Davis is known for bicycles, energy conservation, and a preference for slow, carefully managed
growth. Its notable physical characteristics are small scale in relation to UCD, innovative
neighborhood design, a traditional downtown, and an absence of large scale shopping centers.
BACKGROUND
The University has always had a significant impact on the City of Davis. Historically, the
population and geographic spread of the City has been driven by University enrollment. The
ratio of City population to UCD enrollment has been steady at about 2: 1 over the last twenty
years. There is, however, a dramatic shift in demographics now occurring within the City. As
the Interstate 80 corridor continues to grow between San Francisco and Sacramento, Davis is
becoming the new "suburb" or "bedroom community" to larger cities in northern California,
such as Sacramento. There also appears to be a growing number of city residents that commute
to the San Francisco Bay Area.
Significant use of bicycles in the vicinity of Colleges and Universities is not uncommon.
Bicycles serve the transportation needs of students, faculty, and staff in this setting perhaps better
than any other mode. As the university grew from about 2,200 students in 1958 to its current
enrollment of approximately 30,000, the demands for adequate bicycle facilities and
minimization of bicycle-motor vehicle conflicts have continued to increase. The boundary
between the University Core and the City has not appreciably changed during this period of
student growth. Traffic data suggest that the bicycle is probably the dominant transportation
mode for trips crossing the City-University boundary. By the mid-l 960's it became apparent that
the existing street network, designed and delineated only for motor vehicles, was inadequate to
provide for both bicycle and motor vehicle volumes in the vicinity of the University. A plan to
adequately provide for cyclists was needed.
The transportation system pressures described above were finally resolved within the system and
processes of municipal government. The primary issue of the April, 1966 City Council election
was the provision of bikeways for commuters on the public streets. The pro-bikeway candidates
were elected. A trial system of bike lanes was quickly installed and proved immensely popular.
Rapid expansion of the system followed. The City bikeway system has steadily and consistently
expanded and matured to its present state. The City of Davis has attained national preeminence
in bikeway planning and design through its experience and lessons learned during the evolution
of the system.
CURRENT CONDITIONS
Nearly four decades after the City began to actively promote bicycling for transportation Davis
was recognized as "America's Best Cycling City" by the Bicycle Federation of America in 1995.
The League of American Bicyclists designated the City of Davis as a "Bicycle Friendly
Community" in May, 2000 and in October, 2005 the League awarded the City of Davis "Bicycle
Friendly Community" status at the Platinum level -the highest level ever awarded to a city in
the U.S. Other communities were given Gold, Silver, or Bronze awards. With an area just under
ten square miles, Davis has approximately 50 miles of bike lanes and 52 miles of bike paths.
More than 90% of all the collectors and arterial streets within the City have bike lanes and/or
bike paths.
As a result of aggressively planning for bicycle transportation, ridership within the City is quite
high. Estimates from the last census (2002) indicate that approximately 17 percent of all
journey-to-work trips are made by bicycle. For most cities, 2% - 3% is considered significant.
Although it is recognized that the population of the City has increased, and that the
demographics have changed as well, there continues to be a dedicated population of cyclists that
utilize bicycles for their primary commute mode. For example, at UC Davis, where the majority
of students live off campus, approximately 15,000 students ride a bike or walk as their primary
mode of getting to class ( 48%). This is in addition to the 1,800 faculty and staff members that
also walk or ride their bikes to campus (20%). Many of the university based bike commuters
live in Davis, but others pedal from as far away as Sacramento or Woodland.
For the rest of Davis residents, the mode share is also quite high. There are no public school
busses used by the Davis Joint Unified School District, so most of the school aged children walk
or ride their bikes to school. For many of the younger children, parents that commute to work on
bikes will transport them in bike trailers, and drop them off on their way to work. Out of a
population of 64,000 residents, it is estimated there are over 60,000 bikes in the City of Davis.
Although a 17% mode share for bicycles is still quite high, the share has decreased from where it
was 10 -15 years ago. The 1990 census indicated that the percentage of all journey-to-work
trips being made by bicycles was hovering around 20 -25%. It is apparent that the City of Davis
2
must still continue to work hard, particularly by education and encouragement to increase the
level of bike ridership if it is to remain "America's Best Cycling City."
City of Davis Bicycle Advisory Commission
In February of 2005, the Davis City Council established the Bicycle Advisory Commission to
address bicycle issues related to education, enforcement, engineering and encouragement. In
order to expand public participation in addressing these issues, membership of the Task Force
includes representatives from the general public, the Davis Bike Club, UCD Administration, and
UCD students, among others.

GOALS AND OBJECTIVES
It is the goal of the city of Davis to create and maintain, through this plan, an integrated system
of bicycle facilities. These facilities provide safe, convenient travel for bicyclists throughout the
City. The City recognizes the need to encourage bicycle travel for both transportation and
recreation. Bicycle use conserves energy, contributes to cleaner air, reduces traffic, reduces the
need for automobile parking, and improves personal fitness.
The city's General Plan Update, last updated in 2001, refers to bicycles in various elements
contained in the plan. Chapter IV-2, the Mobility element, contains many of the goals and
policies relating to bicycle and pedestrian circulation.
GENERAL PLAN UPDATE BICYCLE POLICIES
Guiding Policies
-Assure safe and convenient bicycle access to all areas of the city.
-Promote use of bicycles as a viable and attractive alternative to cars.
Implementing Policies
-Provide bicycle lanes along all collector and arterial streets.
-Consider bicycle-operating characteristics in the design of intersections and traffic control
systems.
-Develop and implement bicycle parking standards.
-Maintain an education program to promote bicycle use and safety.
-Require compli ance with bikeway policies and standards for new development including
bikeways within greenbelts. Ensure interconnection of new facilities with the existing
bikeway system.
BICYCLE PLAN GOALS AND OBJECTIVES
The Ad Hoc Bicycle Task Force, which provided the last update to the City of Davis
Comprehensive Bicycle Plan in 2001, had previously developed the following Goals and
Objectives to provide greater detail than the General Plan Goals and Policies they support.
These Goals and Objectives provide specific guidance to the city for further development of
bicycle programs. The Bicycle Plan's guiding policy is to promote bicycle use as a viable,
attractive, healthy, non-polluting form of transportation and to assure safe and convenient access
to all areas of the city. The four "E's" (Education, Enforcement, Engineering and
Encouragement) contribute to enhanced bicycle use.
5
GOAL: Maintain a comprehensive and coordinated bicycle program.
Objectives:
1. Ensure adequate funding is available to continue the bicycle program
within the Public Works Department.
EDUCATION
The issues of bicycle safety cannot be fully addressed without mentioning the importance of
educational programs. Much of the bicycle crash data shows that the preponderance of bike
collisions involve improper actions on the part of bicyclists , motorists, or both. Therefore,
crash reduction efforts need to include educational programs to increase awareness of improper
motorist and cyclist actions that are known to contribute to crashes and to promote correct
actions for both. The education program must include components for bicyclists as well as
motorists. The city's on-going bicycle education programs have contributed greatly to the
excellent bicycle safety record in Davis, as have the enforcement activities of the police
department. In addition, the proposed goals and objectives developed by the Bicycle Task
Force have strong components of education and safety.
Formal education programs alone will not provide all the needed education on bicycle safety.
It is important that parents inform themselves of the proper safety considerations and pass these
on to their children. Parents must train their children and regularly monitor their actual
performance when riding a bicycle. Also, adult bicycle drivers must inform themselves of the
rules and regulations for safe operation of a bicycle just as they would for safe operation of a
motor vehicle.
GOAL: Enhance educational programs to teach children and adults safe
bicycle driving techniques.
Objectives:
1. Support and enhance existing programs that promote safe driving
techniques and make the information available through schools, work sites and
general publicity efforts.
2. Expand and support a citywide helmet promotion program.
3. Investigate other safety programs (e.g. the League of American Bicyclist's "Bike
Ed") that should be taught to school-aged children as well as adults.
4. Investigate development and promotion of a monthly "riding tips"
clinic aimed at new riders.
6
GOAL: Provide literature and current bicycle route maps for public use.
Objectives:
1. On a regular basis, update the UCD/City of Davis bicycle map for public use.
The map, free of charge, shall be distributed to employers, bike shops, public
buildings and schools.
2. Acquire or develop literature promoting appropriate bicycle laws, safety
tips, bike commuting, etc., for dissemination to the general public.
ENFORCEMENT
The city council should adopt more effective procedures for dealing with "abandoned" bicycles.
There is an ordinance already in existence that allows for the removal of some abandoned
bicycles that are blocking the public right-of-way, but the ordinance needs to be more
comprehensive. There should also be provisions for dealing with bicycles that are abandoned at
apartment complexes, bus stops and other locations where bike racks get so clogged with bikes
that other cyclists cannot use them. Once adopted, these provisions should be freely distributed
to business owners and apartment managers, and the general public should be thoroughly
educated so that abandoned bikes can be identified and removed in a timely fashion.
GOAL: Continue the enforcement of bicycle rules and regulations in order to
reduce violations and crashes.
Objective:
1. Study bicycle/auto crash records and develop a focused enforcement effort
with the goal of reducing crashes by 10 percent .
GOAL: Enhance educational programs with emphasis on bicycle safety and laws
relating to bicycle driving.
Objective:
1. Strengthen educational programs used for traffic violators.
GOAL: Promote programs that reduce incidents of theft and continue efforts to
recover stolen bicycles.
Objectives:
1. Develop informative material for use with schools, neighborhood groups,
DCN and Cable TV on incidents of bike theft from private property.
2. Promote bicycle-licensing system.
7
GOAL: Police Enforcement of Traffic Laws
Objective:
1. The Police Department should seek out effective training that will enable
it to become more sensitive to bicycle issues and laws related to
bicycle enforcement.
2. Seek changes in county court procedures to allow court appearance in
Davis for bicycle rider traffic law violations.
ENGINEERING
For decades, the city of Davis has led the nation in the design and construction of innovative
bicycle facilities. Most of the engineering guidelines resulting from these efforts have already
been adopted, and are contained in "Appendix 2: Engineering Standards and Guidelines," of this
document. However, there are still some aspects of the city's bicycle network that continue to
evolve, or they have remained on the forefront because they continue to be an issue with local
cyclists. One such issue is traffic calming. The primary purpose of traffic calming is to reduce
motor vehicle speeds, particularly in residential areas. Traffic calming projects are ostensibly
undertaken for the benefit of bicyclists and pedestrians. However, without careful planning and
design work, the traffic calming improvements may actually may have an adverse impact on
cycling and walking. An analysis should be conducted by staff to evaluate which type of traffic
calming measure is appropriate for a given location. Based on thi s evaluation and the subsequent
development of criteria, guidelines should be adopted by the city to ensure the appropriate siting
and design of traffic calming projects.
The city of Davis has been using a traffic control device for a number of years known as a
"bicycle signal head." These are similar to a standard traffic signal, except that it uses red,
yellow and green bike icons rather than red, yellow and green "balls." Bicycle signal heads are
commonly used around the world in such places as the Netherlands, England, Germany, and
China. The city of Davis began using this type of traffic signal to help expedite the safe
movement of bicycles through the city's more heavily used intersections (one intersection where
these are in use has had counts of more than 1,000 bicycles an hour). The city of Davis is the
first city in the country to utilize this innovative traffic control device, and the city was the
driving force in getting California traffic laws changed in order for its use to be allowed on
public streets. These new traffic signals have performed admirably since the city began using
them on a trial basis in 1990. Bicycle circulation was enhanced and safety has been improved at
locations where these have been installed. Staff should continue to evaluate additional locations,
as appropriate, for this type of signal.
8
GOAL: Placement of Yard Debris in Bike Lane
Objective:
1. When yard and garden waste is piled by the edge of the road and begins to
block the bike lane, it becomes a significant safety hazard. The hazard is that a
cyclist may actually collide with a pile of debris, or worse, cyclists may suddenly
veer out of the bike lane into the motor vehicle travel lane to avoid debris, and
collide with a motor vehicle. The city should reconsider the way in which yard
debris is picked up. At a minimum, there needs to be a concerted effort to better
educate residents as to proper procedures for putting the waste out for collection
in order to minimize hazards for bicycle drivers.
GOAL: Planning for Bicycles in New Developments
Objective:
1. Planning Department staff and the city's Planning Commission should become
more fam iliar with the guiding principles of a good bicycle and pedestrian
transportation system, and with the guidance of the Public Works Department,
ensure that these are used in the design of new developments.
GOAL: Provide bike lanes along all arterial and collector streets. Provide
separated bike paths adjacent to arterial and collector streets only where justified,
with full consideration of potential safety problems this type of facility can create.
Objective:
1. Develop standards to be used for planning decisions on where to place
pathways adjacent to arterials. Issues such as speed and volume of motor
vehicles, number of driveways and other curb cuts, and the age and skill level of
the bicycle driver shall be considered.
GOAL: Ensure that bicycle routing is an integral part of street design so that lanes
and pathways form an integrated network.
Objective:
1. Identi fy weak links and discontinuities in the existing network, and develop a
plan for prioritizing and funding solutions.
GOAL: Consider bicycle-operating characteristics in the design of bikeways,
intersections and traffic control systems.
Objective:
1. Develop standards for signal timing to faci litate movement of bicycles at
intersections.
9
GOAL: Coordinate and cooperate with surrounding jurisdictions such as UCD,
and Yolo and Solano counties, to create a continuous and interconnected
bikeway network.
Objectives:
1. Participate in regional bicycle and pedestrian planning activities such as
the SACOG Bicycle and Pedestrian Advisory Committee. The Yolo-
Solano Air Quality Management District's Bicycle Advisory Committee,
and the Woodland-Davis Bikeway Steering Committee.
2. Comment on Yolo County Bikeway Plan revisions and assist in identifying
improvements needed in the network.
GOAL: Improve the campus-to-core bikeway along Third Street.
Objective:
1. Continue efforts to improve surface quality and safety of the railroad
at-grade crossings at Fourth and Fifth Streets.
GOAL: Promote intermodal transportation.
Objectives:
1. Enhance and maintain a multi-modal transportation center in the Core
Area.
2. Where appropriate, promote the transport of bicycles on all public
transportation systems serving the city.
GOAL: Provide adequate bike parking.
Objectives:
1. Research the best bicycle parking fac ilities available, such as lockers and
secure racks, and provide guidance for appropriate installation in all new
developments, businesses and business expansion.
2. Develop a complete plan for bicycle parking in the Core Area and
integrate it with the revised Core Area Specific Plan.
3. Formali ze standards for bicycle parking requirements related to new
development and incorporate into the Bicycle Plan.
10
GOAL: Design bike routes as integral parts of new greenways, open space areas
(where appropriate) and "greenstreets" to complete and expand the.
existing bikeway system.
Objectives:
1. Develop criteria for bicycle access to open space areas preserved outside
the city limits. The criteria should be available for open space plan
consultants.
2. Adopt standards for the mixed use of off-street routes by bicyclists,
pedestrians, equestrians, skaters and persons with disabilities.
GOAL: Plan bikeways to provide attractive, shaded linkages between destinations.
Objective:
1. Explore alternative street cross-sections for collectors and minor arterials
that will result in more shaded bike lanes
GOAL: Freeway Interchange Safety Improvements
Objective:
1. Crossing freeway interchanges is potentially hazardous for bicyclists
because of the fast merges that automobiles make as they enter and exit the
freeway. The city should work with and encourage Caltrans to study
various ways to minimize this problem such as signalization, signage, or
modification of the intersection geometry (e.g. "T" intersections).
GOAL: Bicycle Circulation Enhancement
Objective:
1. The city should consider the development of a comprehensive bicycle
circulation plan. Elements should address the guidelines for installation of
bicycle signal heads, bicycle detection mechanisms at intersections
controlled by traffic lights, feasibility of separated signal phases for bikes
and motor vehicles, traffic calming, and the determination of where
separated bike paths are appropriate.
GOAL: Maintain roadways and bicycle related facilities so they provide safe and
comfortable conditions for the bike driver.
Objectives:
1. Complete efforts to establish a routine inspection program for all Class I
facilities.
11
2. Develop a list of priorities for pathway overlay and reconstruction to be
considered during budget preparation.
3. Develop a procedure for routine inspection and maintenance of bicycle parking
facilities.
GOAL: Design bicycle facilities to minimize maintenance costs by specifying
quality materials and standard products.
Objective:
1. The city's policy of building its bike paths out of concrete should reduce bike path
maintenance problems. Additional funds should be programmed each year to
maintain the asphalt bike paths that have already been developed. Additionally, a
program should be developed for the cleaning and repair of bike paths on a
regular basis, because these are sometimes covered with broken glass, mud and
encroaching vegetation. Maintenance problems on bike paths not only cause
mechanical difficulties for bikes (e.g. flat tires), but adverse conditions can also
be a deterrent to individuals just beginning to commute by bike.
GOAL: Bike Path Maintenance
Objectives:
1. The city already has an annual bike path resurfacing program, but there
are still problematic areas that need to be addressed. Rather than
continually spending limited funds on recurring maintenance problems, a
preferred approach would be to avoid practices that are major contributors
to accelerated bike path deterioration. Specifically, problem areas include
the following:
• Maintenance and construction vehicles driving on the bike paths are a major
contributor to deteriorating bike path conditions. The use of full-sized motor
vehicles, mainly trucks, that use bike paths as shortcuts when it is not always
necessary, should be minimized. Smaller sized vehicles such as electric "golf
cart" or "Cushman" type vehicles should be considered by the city and used
whenever possible. There are also many types of human powered vehicles that
may be appropriate. Additionally, policies should be developed that will only
allow emergency vehicles and other vehicles that specifically have to get to a
portion of the bike path for maintenance purposes. Indiscriminate use of the bike
path network by city vehicles should be prohibited.
• Bike path degradation due to over-watering is exacerbated by the problem
referenced above. Heavy vehicles driving over bike paths with a soaked and
unstable base causes them to deteriorate more quickly. The city should look at its
watering practices, particularly near bike paths.
12
ENCOURAGEMENT
GOAL: Establish a centralized program for interaction with and education of the
public.
Objectives:
1. Hold an annual fo rum in conjunction with major bicycle events to receive
input on the bicycle program, as well as to educate the public as to the benefits of
the program.
2. Publish an annual report summarizing bicycle program activities and
accomplishments.
GOAL: Increase local coverage of bicycle events and present accurate information
about bicycle safety and activities.
Objectives:
1. Include articles on bicycle issues in the city's newsletter, and distribute to
local newspapers.
2. Establi sh a "bicycle column" in the Davis Enterprise.
3. Place advertisements in the local newspapers to promote bicycling.
GOAL: Share information and resources with UCD regarding bicycle activities.
Objectives:
1. Continue liaison with UCD via Committee on Bicycle Programs.
2. Continue/expand annual events where the city and UCD join efforts to
promote bicycling.
3. Investigate joint sponsorship of special bicycling events.

Davis General Plan
APPENDIX 1
BICYCLE FACILITY GUIDELINES
The City of Davis has been developing bikeways for nearly 40 years. During this period, bicycle
use as a primary mode of transportation has steadily continued to increase. The most recent
census figures indicate that approximately 17 percent of all trips in Davis are made by bicycle.
As the cycling population continued to grow, the bicycle transportation network continued to
grow and evolve as well. The development of the city's bicycle transportation system over the
years, and the lessons learned during that time, have helped to evolve a set of bicycle facility
planning principles that have served the city well. Additionally, the standards that have been
developed have benefited other jurisdictions within the state as well as other parts of the country.
In order to ensure these systems are functioning as safely and as efficiently as possible,
procedures to effectively resolve bicycle circulation and safety issues have been institutionalized
so that these issues are dealt with routinely.
CYCLIST POPULATION
The bicycling population in Davis is comprised of wide and diverse segments with differing
skills and abilities, as well as differing motivations for cycling in the first place. The type,
location, and characteristics of bicycle facilities must necessarily take into account these
segments of drivers if they are to be served adequately. A given set of bicycle facilities and
routes wi ll not be suitable for the entire cycling population. The following li st is one attempt to
classify this population into identifiable categories:
1. Avid cyclists. Considers the bicycle as the primary transportation mode for most
trips. The availability of direct, high speed routes that are relatively unfettered by traffic
lights and stop signs is important. The avid cyclist will often choose to ride in the motor
vehicle travel lane, and along major routes without separate bicycle facilities. This group
of experienced cyclists will typically shun separated bike paths, particularly in
neighborhood greenbelts. Avid cyclists are highly attuned to bicycle safety, so they are
sensitized to potential hazards, and they continually anticipate and avoids compromising
situations while riding. This group, although typically the most visible and vocal
component of the bicycling community, is actually a relatively small segment of the
cycling population.
2. Regular bicycle riders. This group of cyclists will typically utilize a bicycle as a
preferred transportation mode, provided that the destination is reasonably close and a
good bicycle route exists. The individuals in this group are usually working adults, UCD
students, or mature high school students. This group also includes parents with child
seats/carts. They appreciate the relative speed and convenience of the bicycle as
compared to the car. These cyclists desire safe and efficient bicycle facilities and routes.
They are willing to accept some out of direction travel to avoid perceived hazardous
locations. Some cyclists in this group feel uncomfortable riding along high speed arterial
streets even when bike lanes are provided. They are usually attuned to potential hazards
14
such as opening car doors, and cars exiting or entering driveways. The regular bicycle
rider wants to maintain momentum but usually obeys traffic controls. This type of cyclist
comprises a large segment of the cycling population in Davis
3. Young regular bicycle riders. This is usually a child of junior high or high school age
who routinely rides to and from school. Other trip purposes include riding to visit
friends, to the park, to shop, and for other after school activities. This group of cyclists
tends to have less experience negotiating traffic, so they are not always aware of potential
hazards. They may choose routes unsuitable to their ability, and they often disobey
traffic laws and traffic control devices. This group of cyclists tends to prefer the shortest
route possible, because minimal pedaling effort seems more important than speed, and
they tend to prefer bike lanes and bike paths. In Davis, this is a large segment of the
cycling population.
4. Beginning bicycle rider. These are school age children up to about the fourth grade
level. They ride bikes to and from school only if a route exists consisting of bike paths
and bike lanes on streets with relatively low traffic volumes. Beginning bike riders will
typically only pedal to destinations in their neighborhood, and they seldom ride bikes
across town. They are not "little adults" as some people seem to think, but individuals
within the bicycling community that have very real experiential and physiological
limitations. Cycling skills are not fully developed in this age group, and most of them
have relatively limited experience riding a bike in traffic. Developmentally, this age
group has physical limitations as well. Up to about age nine or ten, most children do not
have well developed peripheral vision, and they have difficulty with concepts such as
closure speed (e.g. approaching motor vehicles). Younger bicycle riders typically have
difficulty following a straight track, and they frequently weave from side to side when
riding. Beginning bike riders are a relatively smaller segment of the cycling population.
There are other ways that cyclists can be categorized, such as by trip purpose. The descriptions
detailed above only serve to represent the major categories of cyclists in Davis, but they do not
imply that the categories are exclusive, or the descriptions absolute.
ROUTE SELECTION
Route selection factors commonly used by bicycle facility planners include factors such as:
Rider Safety -Routes are chosen considering various safety factors, including traffic
volumes, motor vehicle speeds, shoulder width, and the presence of parked cars.
Rider Convenience -Convenience factors usually considered include most destination
points, fewest stop signs, most side streets with stop signs, and least debris on shoulders.
Rider Volume -Emphasis placed on limiting the number ofbikeways designated in order
to concentrate on bikeways with the highest bicycle volumes.
15
Selection criteria such as the above would result in too limited a bikeway system to adequately
provide for the cycling population in Davis. In order to increase the already high use of bicycles,
it is necessary to provide adequate routes for all segments of the cycling population. These routes
must serve all combinations of origins and destinations across the city. This cannot be done by
designating and developing a skeleton of high priority bike routes.
The existing and future street and bicycle networks are planned to safely and adequately provide
for bicycle circulation. Bike lanes exist or are planned along all arterial and collector streets. In
addition, Class I bicycle facilities are provided in neighborhood greenbelts and along high
demand bicycle corridors. A more austere circulation system would not meet the goal of
providing safe and convenient bicycle access to all areas of the city.
ROUTES SELECTED
The bikeway system is shown on the City Bikeway Map (please see Appendix 7). Both existing
and planned facilities are shown. The planned facilities serve to augment the existing system,
correct specific deficiencies, and extend the network to newly developing areas. Several features
of the System are worthy of note:
-Bike lanes are shown along all arterial and collector streets. (with the exception of Fifth
Street west of Pole Line Road)
-Grade separated facilities are provided to facilitate crossing of busy streets and
highways.
-Class I facilities (bike paths) are provided within neighborhood greenbelts.
-Class I facilities are shown to provide alternative facilities to using on street bike lanes
along high traffic routes.
-Continuity of the system is important and wherever possible, all facilities are joined in
a network providing continuous service for cyclists.
Since this bikeway system extends throughout the City, it accommodates the commuting needs
of employees, shoppers, faculty and students regardless of the trip origin or destination. These
facilities are included as part of the normal street design and construction process. Land use
adjacent to bikeways includes all the land uses within the city. Since the policies contained in
this plan require integrated bikeways throughout the city, all land uses and combinations of
bicycle trips are accommodated. Land use designations in the City of Davis are contained within
the General Plan and the various other plans and maps maintained for that purpose. See Figure 1
for a general picture of land uses. For specific land use designations adjacent to bikeways,
reference is made to those documents.

APPENDIX 2
ENGINEERING STANDARDS & GUIDELINES
STATE DESIGN STANDARDS
Chapter 1000 of the CAL TRANS Highway Design Manual is the guiding reference for planning
and design of bikeways. The cases where City of Davis guidelines are more stringent are
identified below. It must be emphasized that a careful evaluation of conditions for a specific
bikeway may justify an easing of some requirement or necessitate a more stringent requirement,
as the case may be, for the appropriate reasons. Therefore, these guidelines are not absolute
standards but rather a guide to be used as a point of beginning when planning new facilities or
improving performance of existing facilities.
BICYCLE FACILITIES DESIGN
A. Design speed
The selected design speed of a bikeway faci lity is the single criterion that dictates facility
geometry to result in safe bikeways. Therefore, the selected design speed for a bikeway segment
should be the uppermost speed expected for the bulk of riders using the facility. The design
speed for bikeways within the City of Davis is 20 MPH. For downhill grades exceeding 4
percent, the design speed is increased to 30 MPH.
B. Grades
For most facilities, sustained grades should not exceed two percent if a wide range of riders is to
be accommodated. However, undercrossings and overcrossings cannot be limited to this grade
criterion however, due to the vertical rise that such structures typically require. Fortunately, the
city landscape is nearly flat in most areas, thereby eliminating grade limits as a significant design
parameter except for grade-separated crossings. The safety of a given grade is based on criteria
for stopping sight distance, which, in tum, is dependent upon grade and design speed.
Much of the literature suggests that grades should be kept to 5 percent or less where possible.
The reasons for this are that cyclists may avoid facilities with steeper grades, or that some
cyclists may be unable to negotiate the grade due to physical limitations. Aside from the
practical aspects of minimizing grades whenever possible, the Americans with Disabilities Act
(ADA) prohibits the construction of facilities steeper than 5 percent to ensure access to
individuals with disabilities.
There are two primary safety issues with steep grades. If overcrossing grades are too steep,
cyclists may seek an alternative at-grade crossing at an unsafe location to avoid the effort of
using the overcrossing. For undercrossings or bike tunnels, if the grades are too steep, cyclists
may choose to attain unsafe speeds while descending in order to gain momentum to negotiate the
ascending grade. Other than these two situations, steeper grades do not create safety problems
while ascending or descending, provided adequate stopping sight distance is maintained. Of
course, factors such as debris on the roadway, weather, and the mechanical condition of the bike
also have an effect on stopping distance.
Another factor to consider about grades is the distance that a given grade persists. The
acceptability of a relatively steep grade depends on the length of the grade. Steep grades are
17
tolerable for relatively short distances and are preferable as an alternative to much lesser grades
that last long distances.
C. Grade Separated Crossings
This plan provides for some grade separations where separated bike paths cross arterial streets
and highways. Such crossings are planned to provide for relatively unimpeded bicycle routes
interconnecting all areas of the city and the University. Additionally, grade separated crossings
afford continuity along neighborhood greenbelt bike paths by eliminating the need to cross
arterial streets at grade.
1. Undercrossings
The preferred grade separation is the undercrossing because it allows shorter and flatter
approaches than an overcrossing. However, close attention to the design is needed because of
the bicyclist's tendency towards excessive speed in an effort to contend with the adverse
ascending grade. Therefore, approaches should be kept to no more than 5 percent grade. In
addition, the roadway should be raised so that the upper portion of the bicycle tunnel is above the
elevation of the surrounding terrain. This design approach usually allows relatively short
approaches of modest grade thus moderating the tendency to excessive speed in the tunnel. In
addition, this design feature may allow drainage to be accomplished by gravity. Undercrossings
shall be fully lighted for safety. Finally, visibility into and through a raised tunnel enhances the
sense of safety compared to a deeper structure with less visibility.
2. Overcrossings
Overcrossings are generally needed where roadway curb-to-curb width exceeds about 90 feet due
to concerns of personal safety. Steep grades should be moderated as much as possible so that
ridership is not unduly discouraged. Grades exceeding 4 percent for downhill travel do not, by
themselves, create a safety problem, provided that safety criteria derived from the 30 MPH
design speed are followed. For ascending cyclists, a combination of length and grade should be
selected that carefully balances the two as necessitated by the total climb required. Short, steep
grades are preferable to modest grades of 2-4 percent, if those modest grades must persist for
distances significantly in excess of 500 feet.
D. Typical Cross Sections
The bicycle facility cross sections depicted in Figure 2 are the desired minimum widths for these
facilities within the City of Davis. Lesser widths may be considered for low volume
streets/paths, existing roadways narrower than city standards, or where other circumstances
warrant. State bikeway standards shall be considered the absolute minimum when considering
deviations from these guidelines.
18
E. Intersection Considerations
Intersections are the problematic locations where many bicycle/auto conflicts occur. Skilled
cyclists usually have little problem making the appropriate transitions when using on-street
lanes. Lesser skilled bike riders may have difficulty performing weaving maneuvers near
intersections safely. These bicycle drivers need alternate, less demanding routes as an alternative
to using the on-street bike lanes. When using such alternate routes, the cyclist will still need to
cross busy arterial streets, usually at signalized intersections. Special loop detectors, which can
detect bicycles, as well as bicycle oriented signal call buttons can all facilitate the crossing.
Bicycle routes typically used by younger children need to provide protected signalization for
crossing major streets, both at intersections and at other locations where crossings are needed.
Grade separated crossings are an alternative to protected at-grade crossings. Such crossings tend
to be very expensive, which limits where they can be considered to only a few high priority
locations. Neither bike overpasses nor underpasses work well near intersections. The crossing
length is longer and there is not the opportunity to adjust the road grade to shorten the slopes of
the crossing. Also, the transitions between on-street lanes and the separate crossing path create
the possibility of unsafe movements. Underpasses can prompt personal safety concerns if their
required length is too great and/or visibility through the underpass is limited.
Research has shown that the majority of bicycle/motor vehicle crashes occur at intersections.
Therefore, special consideration must be given to bicycle and vehicle movements at
intersections. Bicycle lanes enhance visibility between bicycles and motor vehicles and provide
the best opportunity for a safe interaction between vehicles. Typical treatment of these lanes is
shown in Figures 3, 4 and 5. Note that a weaving section of sufficient length, considering
prevailing vehicle speeds, is essential for the left tum and through bicycle lanes to be effective.
Figure 5 shows typical intersection treatment where a Class I facility interacts with an
intersection. The bike path may or may not continue beyond the intersection. The advantage of
this intersection design is that it places the bicyclist in a predictable location and minimizes the
distance to cross opposing vehicle lanes during the prescribed signal phase.
Figure 6 displays a plan view of a street segment constructed with a continuous center left tum
lane. This lane, combined with on-street bike lanes creates a bicycle friendly route by making it
easier and safer to cross the street compared to a four-lane road. Figure 7 provides some
additional information about the traffic islands for bicycles at arterial intersections. These
islands make it easier for bicyclists to approach the intersection, make a convenient and safe
crossing, and then continue along on available routes in any direction.
F. Roundabout Design and Operation
Within recent years, the City of Davis has begun using roundabouts as traffic control devices,
where appropriate. Roundabouts also tend to provide a measure of "traffic calming". Although
the use of roundabouts has been common in a number of countries for many years, particularly in
Europe and Australia, their potential for reducing conflicts between motor vehicles, bicycle
riders and pedestrians has contributed to their design and construction in Davis. Roundabouts
improve safety for all road users by simplifying conflicts, reducing motor vehicle speeds, and
providing a clearer indication of right-of-way relative to other types of intersection controls.
Figure 8 illustrates a generalized design standard for what is currently being used in Davis.
19
Although navigation through a roundabout may appear daunting for cyclists and pedestrians the
first time one is encountered, their operation is actually quite simple. For cyclists, the first thing
to remember is that the bike lane is dropped prior to entering the roundabout, just as it is at more
conventional intersections. This is done so that a through cyclist is not "cut off' by a right
turning motorist. The cyclist merely "takes the lane", which is made easier by the fact that
motorist's speed is reduced by the design of the roundabout due to "deflection". Within the
circulating roadway, the speed of motorists and bicyclists speed are more closely matched, which
makes the process of merging into the circulating roadway easier. As the cyclist approaches the
roundabout, they must yield to any other bicycles or motor vehicles already in the roundabout,
and proceed through in a counter clock-wise direction, and then turning right as they approach
their intended direction.
The design concepts of roundabouts also makes it safer for pedestrians. Crosswalks run through
the middle of the "splitter islands" that create the deflection for bicyclists and motor vehicles.
These islands provide a refuge for pedestrians between traffic lanes, so that they only need to be
concerned with one conflicting movement of traffic as they cross the street.
G. Bike Lanes
Bike lanes provide a significant benefit to safe and efficient bicycle circulation. Conflicts
between bikes and autos are dramatically reduced when on-street lanes are installed. Having
separate identifiable areas on the street for bikes and autos places the travelers in predictable
locations.
Generally, bicycle lanes are provided or planned for all collector and arterial streets. The city's
guideline width for on-street bike lanes is 8 feet when adjacent to the curb where no parking is
permitted and 7 feet where parking is allowed. Where parking is allowed, the total width from
the curb to the bike lane line is 15 feet. There is a consensus among bicycle planning and safety
experts that bike lanes constructed to the Davis guidelines are appropriate.
Bike lanes may be unsuitable for bicycle riders that lack the necessary skills to safely use them
when traffic volumes are heavy and/or vehicle speeds are high. These individuals should
consider the use of alternate routes. There are cyclists who have the desire and skill to use on-
street lanes, such as bike commuters, so these facilities are still very much needed.
Width criteria for bike lanes takes into account that occasional obstructions, such as leaf piles
and yard debris, may exist in the bike lanes that would require bicyclists to steer around them.
While automobiles do sometimes stray into the bike lane and cyclists sometimes stray into the
vehicle lane, these incursions seldom result in crashes. Mid-block crashes between bikes and
cars are rare where bike lanes exist. More common are bike/bike accidents and bikes running
into fixed objects such as parked cars. The majority of bike/car crashes occur at intersections
rather than at mid-block locations.
20
H. Bike Paths
Bike paths, when properly designed and constructed, provide good routes for bicycle circulation
separated from vehicles. Separate bike paths are not always a good choice to replace on-street
lanes when they are along high volume, relatively high-speed arterials. In these circumstances,
retrofitting within the existing right of way to add paths can prove difficult or impractical. In
addition, the presence of numerous driveways, which for the cyclist, function as unsignalized
intersections, can be problematic. Paths within neighborhood greenbelts provide a good
alternative to on-street facilities for large numbers of young and beginning bicycle drivers.
These are being provided throughout newly developing areas.
I. Alternative Routes
Good bicycle circulation can best be achieved with the appropriate mix of bicycle facilities for
the respective segments of the cycling population. Such facilities will provide reasonably direct
and convenient bicycle access throughout the city. Because the cycling population is segmented,
the infrastructure must provide alternative routes and types of facilities for the respective
segments. While on-street bike lanes along a high-demand route may serve large numbers of
cyclists well, alternatives to bike lanes may be necessary for less skilled drivers.
As an example, the design of the Pole Line Road Overcrossing took into account the varying
needs of cyclists. The route includes on-street lanes because these lanes are needed for a large
segment of the cycling population. A separate path is included on the west side of the structure
to serve those cyclists that feel uncomfortable using the bike lanes or do not have the skills
necessary to use them safely.
BICYCLE PARKING GUIDELINES
The requirement to provide adequate bicycle parking for the various land uses within the city is
contained in the city's zoning ordinance. It is the function of the Design Review Process to
assess the bicycle parking plan of developers and project applicants to ensure that adequate
facilities are provided. The following features shall be considered.
1. The quantity of parking shall adequately consider the nature of the land use, its proximity to
bike routes, and other factors that may affect bicycle parking.
2. Bicycle parking shall be located on the project to promote its use. Bike racks should be
visible and as close as possible to the main entrance or doorway of the cyclist's destination.
3. The bicycle circulation within the project shall be adequately considered to minimize
conflicts and hazards with motor vehicles.
4. Bicycle racks must be conducive for use with the most common locking devices:
"u-locks."
5. Bicycle parking must be illuminated at night.
6. Bicycle parking should be sheltered, if possible.
7. Bicycle parking shall be at least as convenient as the planned motor vehicle parking.
21
8. In order to prevent damage to bicycles, racks must support them with at least two contact
points (e.g. inverted "U" racks). Therefore, some rack types formerly used by the city (e.g.
"ribbon racks") are no longer considered acceptable. Examples of acceptable rack types are
included in Appendix 6.
The amount of bicycle parking needed for a particular project depends upon a variety of factors
such as the type of occupancy, the location and proximity to streets with heavy bicycle traffic,
and the relationship of the project to adjacent and nearby businesses, etc. The following are
suggested amounts of bicycle parking for several types of land use. These amounts can be
adjusted up or down for a particular project as circumstances suggest.
1. For multi-family residential, two bicycle parking spaces per dwelling unit.
2. Commercial, all zones, bicycle spaces numbering 30 percent of motor vehicle spaces
otherwise required.
3. Provide one bicycle space for every two employees during the heaviest work shift in addition
to bicycle parking otherwise required for visitors/patrons. This parking may be located
separately from the public parking but shall be at least as convenient as employee motor
vehicle parking.
4. For public facilities (such as municipal offices, parks, swimming pools, museums, parks,
auditoriums, churches and similar uses), provide bicycle spaces numbering 30 percent of the
motor vehicle parking normally required or immediately available to the facility.
5. Public and private schools K-12, provide bicycle spaces numbering 85 percent of peak
enrollment. For post-secondary, provide spaces at least 50 percent of peak enrollment.
Experience has shown that modest amounts of bicycle parking at many dispersed locations is
preferable to a few high capacity facilities. Cyclists tend to avoid bike parking facilities unless
they are very close to their destination. The best way to determine the need and amount of
bicycle parking is to identify those locations where parked bikes exceed the available parking,
and to find those locations where bikes are parked and no parking is provided. In this manner,
parking can be provided to meet the need. The relocation of unused parking facilities to higher
demand locations can help make available resources go farther.
REST FACILITIES
The city's bike map shows rest facilities (generally day use areas with rest room facilities) that
may be used by bicyclists. Also shown are bike shops and a few points of interest. Since Davis
is an urban area, commercial establishments that provide air, water, shopping, food, telephones,
etc. are readily available either along the bicycle routes or in close proximity to them.
COORDINATION WITH OTHER TRANSPORTATION MODES
Uni trans, Yolo bus, City link and Bay Link provide bus service in Davis. The bus routes used by
these systems are directly served by bicycle facilities. The city's intermodal rail facility brings
together rail, bus, bicycle, and motor vehicle modes at one location. The city provides for the
installation of bicycle parking at bus stops to facilitate bus/bike trips. Additionally, Yolobus and
Citylink have both added bike racks to their buses, and the Amtrak "Capitol Corridor" train has
installed bike racks on their passenger cars as well.

SUMMARY OF ISSUES AFFECTING BICYCLING IN DA VIS
AS IDENTIFIED BY THE AD HOC BICYCLE TASK FORCE
Since the mid-1960's, the city of Davis has led the nation in the design and construction of
bicycle facilities. As a result, this exemplary bicycle network provides the opportunity for
cyclists to travel to all comers of the city with few impediments and even fewer hazards.
However, there are still some issues and conflicts the bicycling community feels the need to
resolve in order to encourage more bicycle use.
These issues are presented in the bike plan more for infom1ational purposes, since some of the
more difficult issues will require much work or long-term solutions with a multi-faceted
approach. As mentioned previously, task force members felt strongly that a permanent bicycle
advisory committee is necessary and appropriate if Davis is to retain its prominence as a
premiere bicycling community. As such, many of these issues should and could be addressed by
the Bicycle Advisory Commission with coordination through existing entities such as the Safety
Advisory Commission.
1. Overriding Theme
Bicycle travel should be considered on an equal level of importance with motorized vehicle
travel in the planning and design of all transportation projects. Bicycles are a legally recognized
mode of transportation, and not just recreational in nature. This implies that bicycle facilities
should be as direct, convenient and safe as the facilities designed for motor vehicles. Davis
should not "rest on its laurels" as "America's Best Cycling City," but should continue to develop
innovative bicycle facilities and policies. There are many good models to follow.
The Dutch bikeway system has often been cited as a good example to follow, but this perspective
is controversial, even among bicycle professionals. It has been pointed out that what will work
in one community, may not necessarily work in another. Also, like Davis, many Dutch cities
have been accommodating bicycle transportation for decades. As a result, many bicycle
facilities were built prior to the development and adoption of standardized guidelines.
Consequently, some of these facilities have proven to be outdated, inefficient, or potentially
hazardous. Also, certain facilities that work well in the Netherlands may not work in the U.S. for
a variety of reasons. These include cultural differences, unique attitudes towards bicycles and
motor vehicles, dissimilar urban design, etc. There are, however, examples from Holland, China,
and other locations abroad and within the United States that could provide examples of favorable
projects from which we could learn.
2. Conflicts with Other Users
As the city of Davis continues to grow and the population increases, potential conflicts with
other transportation modes will be inevitable. Aside from "traditional" conflicts with motor
vehicles, there are growing numbers of electric-assist bikes, golf carts, pedestrians, joggers,
people with baby carriages and dogs, and more recently, a growing number of in-line skaters.
While many of these diverse user groups represent "one less car" (which is a good thing), they
also represent additional challenges to managing the non-motorized transportation network.
23
Bicyclists using bike lanes and bike paths are reporting increased levels of congestion
(particularly from in-line skaters) that will eventually necessitate appropriate action. The Davis
City Council should take appropriate actions to educate bicycle facility users about sections of
the existing California Vehicle Code that already regulate the use of these facilities (e.g. bike
lanes). Additionally, they should consider adopting supplemental guidelines where there are
"gray areas" to supplant existing laws.
3. Bicycle Parking
The city should ensure adequate bicycle parking in public locations. This is a particular problem
in downtown Davis and at transit stops. More definitive guidelines need to be developed that
specifically address bike rack types, quantity and location. Other parameters include minimum
space requirements for the cement pad or sidewalks, including clearance requirements mandated
by the Americans with Disabilities Act (ADA).
4. Traffic Signal Activation
Standards should be developed to ensure that all signalized intersections with signal triggering
devices (e.g. loop or video detectors) are equipped with mechanisms sensitive enough to detect
bicycles. Signal activating push buttons for cyclists' through movements should not be placed
where the only access is to the right of the "right tum only" lane. This configuration puts a
cyclist at risk when they are going straight ahead because of the increased likelihood of being
cut-off by a right turning motorist.
5. Re-establish the City Bike Auction
For many years, the city conducted biannual bicycle auctions through the Davis Police
Department. Abandoned or unclaimed bicycles made available to the general public through
these sales provided revenue to the city and a source of inexpensive bicycles for the community
and the region. Recently the Police Department decided to engage the services of a commercial
auctioneering firm that regularly removes the impounded bicycles to the Bay Area for public
sale. This procedural change, apparently a result of cost and staffing concerns, has raised
questions among some in the community who believe that local residents should have the first
opportunity to bid on these bicycles. The Bicycle Task Force requests the City Council to look
into this issue and explore alternative fiscal strategies that could lead to a reinstatement of the
city bike auctions.
24
APPENDIX4
IMPLEMENTATION AND FUNDING
BIKE PROGRAM FINANCING
Bikeways in Davis may be funded from the full range of financial resources available to the city.
These resources include the General Fund, Construction Tax, development impact fees,
redevelopment monies, Mello-Roos Bonds, and cost participation by other entities. The
appropriate funding is applied to the specific project according to the program or programs to
which the project belongs.
Additionally, bikeway projects may be eligible for State or Federal funding when a bikeway
project meets the appropriate program criteria. These funding sources include the newly enacted
"Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users", or
SAFTEA-LU for short, a Federal program that makes funding available for bicycle projects.
The State of California has also established dedicated funding for bicycle projects as well. For
many years, the California Bicycle Lane Account (BLA) had provided only about $360,000 per
year, statewide~ for bike projects. As a direct result of lobbying by the California Bicycle
Coalition (CBC), this amount was increased to approximately $1,000,000 per year in FY
1999/2000, with a sliding scale that brought it up to $5,000,000 per year by 2004, and annually
thereafter. It was actually up to 7.2 million last fiscal year, but despite aggressive lobbying by
CBC to keep it at this amount, it appears that it will be going back down to 5 million for the
2006/2007 fiscal year. To be eligible for BTA funds, a local agency must have a current bike
plan (as defined in the schedule for each annual application cycle). These plans must address
the elements described in Section 891.2 of the Streets and Highways Code. The account is
administered by Caltrans and a local match is required.
In addition to BT A Funds, another significant funding source for bicycle and pedestrian projects
is the "Safe Route to School," (SRTS) program, which is administered by Caltrans with funding
from state and federal sources.
VARIABLES IN PROJECT FINANCING AND SCHEDULING
Prioritizing bikeway projects in the City of Davis involves a number of variables that include,
but are not limited to the following:
1. Bikeway projects are accomplished from a variety of funding sources and combinations
of funding sources. Every bikeway project does not compete for funding with all other
bikeway projects.
2. Many bikeway projects are undertaken concurrent with a larger project such as a street
reconstruction or widening. The priority of the more significant project often determines
when a bikeway project will be accomplished.
25
3. Many identified bikeway projects are closely linked to, or a result of development. These
projects are often not needed until development actually occurs, and construction of such
projects is dependent upon funding provided by the new development. It is difficult to
predict accurately the timing for these projects due to the many uncertainties inherent to
the development process.
4. Occasionally, the identification, and subsequent accomplishment of a project occurs so
quickly (e.g. due to safety concerns, etc), that programming the project is impractical.
Historically, the greatest deficiency for the city and the university has been the lack of a good bicycle
route connecting south Davis to the university and other destinations north of Interstate 80. The
Mace Boulevard and Richards Boulevard interchanges have been highly congested for years, and to
cross these structures, cyclists must cross freeway on-and off-ramps. For these reasons, projects that
facilitate the safe movement of bicycles across the freeway have had the highest priority.
Improvements to the Richards Boulevard interchange were completed in 1994, and the Mace
Boulevard interchanges improvements have been completed as well. The Putah Creek bicycle
undercrossing, in the planning stages for almost a decade, was finally completed in 2003. This latter
project had a cost of approximately 7 .2 million dollars. Additionally , a bicycle overcrossing of
Interstate 80, immediately west of Mace Boulevard, was completed in 2002. This was named the
"Dave Pelz Bicycle Overcrossing" after the long-time Davis Public Works Director of the same
name.
PROJECT PRIORITIES
Aside from the factors referenced above, the following section details the priorities that are
considered when making project approval and funding decisions on bike projects:
1. Bicycle facility projects with significant safety concerns are accomplished expeditiously, and
placed ahead of system expansion. Projects of this nature are typically submitted to the
Safety Advisory Commission and Bicycle Advisory Commission for review.
2. Projects that will close gaps or improve the operation of the existing bikeway system are
given high priority.
3. Projects that expand the bicycle facilities network, including connections to the existing
system, are analyzed annually as part of the normal budget process. Projects needed to
integrate bicycle facilities provided by development are scheduled and funded during this
annual review process.
4. Bikeway projects that enhance the existing system or bring substandard facilities up to
standard are balanced according to their importance against other competing projects. The
city has an annual program for maintenance and repair of existing bicycle faci lities. These
efforts are not sacrificed by diverting resources to construct new faci lities.

APPENDIXS
ADVISORY GROUPS
The city currently addresses safety issues, including bicycle safety, on a continuing basis. This
function was formerly performed primarily by the Safety Advisory Commission (SAC), with
technical support and guidance from engineering staff. When safety concerns arise, they are
often directed to the SAC for staff investigation and resolution. The on-going "Suggested
Routes to School" initiative is an example of the manner in which potential safety issues are
addressed. The SAC process involves a report prepared by engineering staff (Public Works)
which is then placed on the SAC agenda for action. If a roadway improvement project is
planned near a specific school, bicycle and pedestrian safety and circulation considerations are
included as part of the project development process. These issues are then reviewed by the
Safety Advisory Commission as necessary.
In 2005, the Davis City Council created the Bicycle Advisory Commission, in part to address the
concern among Bicycle Task Force members and other cyclists in the community that adequate
consideration was not being given to bicycle transportation issues other than safety. Although
the Safety Advisory Commission performs an admirable job in responding to safety concerns
across a broad spectrum of issue areas (predominantly transportation related), that commission is
not intended to promote bicycle transportation. The Bicycle Advisory Commission was created
to expand opportunities to improve the bicycle program in Davis.
City and county bicycle advisory commissions, or committees, are standard components of most
successful bike programs nationwide, and they allow for a more comprehensive pursuit of
activities necessary to improve conditions for bicycling. These activities include what bicycle
advocates refer to as the "Four E's" (in relative order of priority):
• Education
• Enforcement
• Engineering
• Encouragement
Whereas the Safety Advisory Commission is primarily charged with addressing the engineering
component of this four tiered approach, the Bicycle Advisory Commission (BAC) is well suited
to pursue the other emphasis areas. A well-informed BAC will help facilitate educating cyclists
and motorists, and work with law enforcement to help reduce avoidable bicycle crashes and the
incidence of bike theft. Finally, the Bicycle Advisory Commission can be instrumental in
helping to develop and implement encouragement programs such as "Bike Commute Day" and
"Cyclebration." Cyclebration is a month-long celebration of the bicycle, which includes
activities such as the "Cyclebration Classic," a day-long festival including antique high-wheeler
races, unicycle races, bike history, music, food and entertainment.
27
Although some cyclists, and parents of younger cyclists, believe that all bicycle safety issues can
be solved through engineering (e.g. bike lanes and bike paths), this is actually just one
component of many that is necessary to make our transportation networks safer for all road users
In the same way that the existing Safety Advisory Commission addresses engineering issues, the
Bicycle Advisory commission is well placed to complement the work of the SAC by pursuing
the remaining emphasis areas necessary to maintain a safe and effective bicycle transportation
system.
An important issue with local bicyclists is the perception that bicycling for transportation is not
as prominent in Davis as it once was. Although bicycle ridership is still quite high, the
percentages are not as high as they were during the l 970's and 80's. A primary goal of the
proposed bicycle advisory committee will be to ensure that cycling increases as a viable mode of
transportation, and to encourage all residents to use bikes more frequently for as many purposes
as possible. This includes commuting, running errands, shopping and recreation.

APPENDIX6
BICYCLE FACILITY CLASSIFICATIONS
Bikeway means all facilities that provide primarily for bicycle travel. Topic 1003 of Chapter
l 000 of the Cal trans Highway Design Manual categorizes bikeways as follows:
Class I
Class I bikeways (bike paths) are facil ities with exclusive right of way, with cross flows by
motorists minimized. Chapter 1000 of the California Highway Design Manual defines Class I
bikeways as serving the exclusive use of bicycles and pedestrians.
Class II
Class II bikeways (bike lanes) provide a restricted right of way designated for the exclusive or
semi-exclusive use of bicycles with through travel by motor vehicles or pedestrians is prohibited,
but with vehicle parking and cross flows by pedestrians and motorists permitted.
Class III
Class III bikeways (bike routes) provide a right of way designated by signs or pern1anent
markings and shared with pedestrians or motorists. It is the policy of the City of Davis that this
class of bikeway not be used.
