Anholm Bikeway Plan Executive Summary 1 February 2018 Executive Summary As originally envisioned in the 2013 City of San Luis Obispo Bicycle Transportation Plan, the Anholm Bikeway Plan (the “Plan”) provides a blueprint to develop a low-stress, priority route for bicyclists and pedestrians between the City’s downtown core and Foothill Boulevard. These improvements will help create a vital multimodal link that not only accommodates bicyclists and pedestrians, but prioritizes safety and mobility for users of all ages and ability levels. This plan supports several key City programs, plans and policies, including the Multimodal Transportation Major City Goal, the General Plan objective to achieve 20 percent bicycle mode share citywide, the Climate Action Plan recommendation to increase use of active transportation modes, and Vision Zero initiative to eliminate traffic-related deaths and severe injuries for all the city’s road users by 2030. Project Description The Anholm Bikeway Plan provides recommended bicycle and pedestrian infrastructure improvements to improve the link between Downtown San Luis Obispo and Foothill Boulevard. The proposed route consists of the following features, starting from Monterey Street in the downtown: Chorro Street (Monterey to Palm): Class III shared lane markings and route signage Chorro Street (Palm to Lincoln): Buffered bike lanes on each side of the street with potential for future installation of physical separation between bicyclists and motor vehicle traffic Chorro Street (Lincoln to Mission): Traffic calming features to reduce vehicle speeds, Class III shared lane markings and route signage Mission Street (Chorro to Broad): Class III shared lane markings and route signage Broad Street (Mission to Ramona): Traffic calming features to reduce vehicle speeds, Class III shared lane markings and route signage Ramona Drive (Broad to Latter Day Saints property): A two-way protected bikeway to replace on-street parking on the north side of Ramona along frontage of the commercial shopping center Bike Path (Ramona to Foothill Boulevard): Class I bicycle/pedestrian path connecting the two-way protected bikeway on Ramona to the planned signalized crossing at Foothill Boulevard A summary map of the proposed project improvements is shown in Figure ES-1. Technical Analysis Technical analysis of the Plan included a traffic analysis, assessment of parking conditions, and review of potential benefits to the bicycling and pedestrian environments. Implementation of the Anholm Bikeway Plan will require removal of 17 on-street parking spaces along north side of Ramona to accommodate the two-way protected bikeway. While the Plan retains street parking along the remainder of the proposed route, and analysis of existing parking conditions finds that there is available street parking nearby to accommodate the proposed parking removal on Ramona, the City supports establishment of a residential parking district—if supported by residents—to address general concerns regarding high demand for parking within the neighborhood. Implementation of the project will create a more comfortable bicycling environment than currently exists and would make significant progress towards establishing a low-stress bicycling corridor with the potential to attract more “interested but concerned riders”. While the improvements proposed in this plan are expected to make significant progress towards increasing bicycle ridership along the corridor, portions of the bikeway route between Lincoln Street and Ramona Drive where cyclists and motorists continue to share travel lanes are likely to remain unattractive to some less confident riders. Project Development Development of this plan included an extensive community-based public engagement effort, focused on understanding the key needs and priorities of residents and stakeholders. Outreach components included public meetings, a project website, and two community surveys. Multiple iterations of the design components were considered before reaching the ultimate design for the Anholm Bikeway.

Anholm Bikeway Plan I. Introduction 5 February 2018 I. Introduction About the Plan In early 2016, the City of San Luis Obispo Transportation Public Works Department began working with the community to develop plans for the Broad Street Bicycle Boulevard project. Identified as a “First Priority” project in the 2013 City of San Luis Obispo Bicycle Transportation Plan, the goal of the Broad Street Bicycle Boulevard was to provide a safe, convenient, low-stress through route for bicyclists and pedestrians connecting the City’s downtown core through the historic Anholm Neighborhood to Foothill Boulevard. The intent of this project is to take a major step towards achieving the City’s goal of 20% bicycle mode share by not only improving conditions for pedestrians and experienced bicyclists who are already comfortable frequenting the streets within this area, but to also provide high-quality facilities that can attract new users of all ages and ability levels—such as families with small children and less-experienced cyclists who are interested in using a bicycle for transportation, but are uncomfortable sharing the existing streets with busy motor vehicle traffic. After nearly two years of community outreach, detailed technical analysis and refinement of design alternatives, staff is pleased to present the end-product of these efforts—the Anholm Bikeway Plan. The Plan is organized into the following sections: Introduction – Page 5 What is the purpose of this project, why are improvements needed and how does this project relate to other city plans, programs and policies? Project Description – Page 10 This section describes the proposed project, including the proposed route alignment, example street layouts and design elements. Analysis of the Project – Page 23 How does the project support the goal and objectives of this planning effort, and what are the key benefits and trade-offs? This section summarizes the technical analysis conducted for the project, considering potential impacts to traffic and parking, benefits to the bicycling and pedestrian environment, influence on neighborhood quality, and overall ability to support the project goal and objectives. Project Development Process – Page 33 How did we get here? This section documents the community outreach activities conducted to develop this plan and summarizes the alternatives development process leading to refinement of the project. Cost Estimates, Phasing Plan and Performance Monitoring Strategies – Page 35 This section presents planning-level cost estimates and summarizes proposed project phasing and performance monitoring strategies. This plan provides a blueprint to guide transportation improvements to create the low-stress route originally envisioned in the Bicycle Transportation Plan and will help create a vital multimodal link that not only accommodates bicyclists and pedestrians, but prioritizes safety and mobility for users of all ages and ability levels. Figure 1: Project Study Area
Anholm Bikeway Plan I. Introduction 6 February 2018 Purpose and Need Broad and Chorro Street are key links to the northern area of the city, serving as primary routes for commuters, students, employees and visitors, connecting Foothill Boulevard to Highway 101 and Downtown San Luis Obispo. With few other north-south route options in this area, these streets carry a greater volume of vehicular through-traffic than typically desired for a residential collector street. Traffic volumes on Chorro currently exceed established maximum neighborhood traffic thresholds and traffic speeds along both Chorro and Broad Street exceed the posted 25 mph speed limit by 20 percent or more.1,2 Traffic conditions within this neighborhood have been an ongoing concern for residents, leading to one of the City’s first traffic calming projects in the 1990’s. While many of the traffic calming features installed along Broad and Chorro Streets in the 1990’s were ultimately rejected for various reasons, there remains strong interest for streets that better balance motor vehicle throughput with neighborhood safety and mobility of other street users. High traffic volumes and speeds on Broad and Chorro not only affect neighborhood quality within the Anholm District, but also limit the viability of these streets as attractive routes for bicyclists and pedestrians off all ages and ability levels. While these streets are designated bike routes in the City’s bicycle network and include shared lane markings (“sharrows”) and signage indicating a cyclist’s right to share the road, current traffic conditions create an intimidating environment for many users—particularly families with school-age children, seniors, and less-experienced cyclists who are not comfortable sharing the lane with autos. As Figure 2 shows, existing traffic volumes/speeds exceed the ranges recommended for streets where cyclists and motor vehicles share travel lanes.3 Similarly, the pedestrian infrastructure within this neighborhood requires improvements to meet the needs of users with disabilities and other mobility challenges. Sidewalks are incomplete in several locations, particularly along the west side of Broad Street, accessible curb ramps are missing at several intersections, street lighting is limited, and the desire for intersection crossing enhancements has been expressed by many residents. To meet the City’s goals for increased walk and bike mode share (as discussed later in this section), street modifications are needed to provide an environment that is safe and viable for users who are interested in walking or bicycling more frequently, but are intimidated by the current street environment. 1 The City of San Luis Obispo General Plan Circulation Element designates Broad and Chorro Streets north of Highway 101 as Residential Collector Streets. For the purposes of maintaining neighborhood quality along residential streets, the City establishes maximum Average Daily Traffic (ADT) threshold of 3,000 veh/day for most residential collector streets, with an increased threshold of 5,000 veh/day for Broad and Chorro Streets north of Highway 101. Existing traffic levels on Chorro exceed 6,000 veh/day. 2 Prevailing vehicular traffic speed refers to the 85th percentile speed, or the speed at which 85 percent of observed drivers are traveling at or below. Thus, 15 percent of observed drivers are traveling above the 85th percentile speed. In 2016, prevailing speeds on Broad Street north of Lincoln Street were measured at 26‐30 mph and at 31 mph along Chorro Street. 3 Source of Recommended Traffic Speed and Volume Thresholds: Federal Highway Administration (FHWA) and National Association of City Transportation Officials (NACTO). Figure 2: Recommended Traffic Speeds and Volumes for Mixed-Flow Street Cyclists on Broad and Chorro often ride within the narrow parking lane, increasing potential for “door zone” collisions
Anholm Bikeway Plan I. Introduction 7 February 2018 Project Goal and Objectives At the start of the planning process for this project, City staff worked with the community to clearly define the overarching project goal and design objectives required to support that goal. While the proposed project does not include development of a continuous bicycle boulevard, as originally envisioned, the initial goal and design objectives remain relevant to the final project. Relationship to Other Plans, Projects and Programs The Anholm Bikeway Plan supports several key City plans, programs and policies: General Plan Land Use and Circulation Elements (2014) – The City of San Luis Obispo General Plan (adopted 2014) provides the overarching vision, goals, policies, and programs for the city and is implemented through city ordinances, regulations, and guidance documents. The General Plan Land Use and Circulation Elements (LUCE) call for investment in a safe, multimodal transportation network that provides viable transportation alternatives to help reduce dependence on single-occupant use of motor vehicles. As summarized in Table 1, the Circulation Element establishes modal split objectives to increase the use of alternate forms of transportation, including a goal to achieve 20% mode share for bicycles and 18% mode share for walking, car pools, and other forms of non-single occupancy vehicular use. Project Goal: Develop a safe, low-stress through route serving bicyclists and pedestrians of all ages and skill levels connecting the City’s Downtown Core north to Foothill Boulevard. Design Objectives: Identity/Branding – Utilize signage, markings and other elements to provide a bicycle route with a look and feel that is unique from surrounding streets to communicate that bicycle travel has a priority on the roadway. These design features should encourage people to walk and bike along this route, while alerting drivers to expect to encounter people walking and bicycling. Traffic Calming – Incorporate design features that bring motor vehicle speeds closer to those of bicyclists, improving the safety and comfort of the bicycle and pedestrian environment, and livability of the neighborhood. Volume Management – Consider measures to separate bicyclists from motor vehicles, and/or explore strategies to reduce/discourage motor vehicle through traffic along a designated route by physically or operationally reconfiguring access along street segments and intersections. Such treatments should consider potential impacts to emergency vehicles and neighborhood access. Pedestrian Safety & Comfort – Incorporate design features along the boulevard that provide a continuous, accessible, low-stress environment for pedestrians of varying ability levels. Where feasible, identify opportunities for streetscape enhancements and green street features to enhance the existing beauty of the neighborhood and improve stormwater management. Crossing Enhancement – Improve accessibility, safety and comfort for bicyclists and pedestrians crossing at intersections. Table 1: General Plan Circulation Element Modal Split Objectives Type of Transportation % of City Resident Trips Motor Vehicles 50% Transit 12% Bicycles 20% Walking, Carpools, and other Forms 18%
Anholm Bikeway Plan I. Introduction 8 February 2018 Bicycle Transportation Plan (2013) – The City of San Luis Obispo Bicycle Transportation Plan (BTP) provides for the planning, development, and maintenance of facilities and activities within the city that are safe and convenient for bicyclists of all ability levels, laying out a network of proposed bikeways to connect the city for travel by bike with special emphasis on travel to schools. The BTP includes the Broad Street Bicycle Boulevard as a “First Priority” project, and identifies this as the City Bicycle Advisory Committee’s highest ranked bicycle route project in the plan. The BTP includes the overall project in two components: Broad Street Bicycle Boulevard – Ramona to Highway 101 & Highway 101 to Monterey: Create a bicycle boulevard to serve as the primary low traffic impact north/south through route for bicyclists and pedestrians connecting the downtown core to neighborhoods north of the downtown core. The alignment follows Broad Street throughout, from Monterey Street north to Ramona and the plan notes that traffic calming may be required. Broad Street Bicycle Boulevard – Grade-Separated Crossing at Highway 101: Provide a lower traffic route bypassing downtown core congestion with the addition of a pedestrian/bicycle grade-separated crossing of Highway 101 connecting north and south segments of Broad Street. Implementation of the grade-separated crossing will require removal of the Highway 101 ramps at Broad Street by Caltrans. The BTP proposes several other bicycle facility improvements within the vicinity of the Broad Street Bicycle Boulevard, including another planned bicycle boulevard on Cerro Romauldo from Patricia to Ferrini, bike lanes on Highland, and intersection enhancements on Foothill at Patricia, La Entrada, and Ferrini. City of San Luis Obispo Major City Goals (2017-19) – As part of each two-year financial plan, the City Council identifies Major City Goals. These represent the most important, highest priority goals for the City to accomplish over the next two years, and as such, the resources to accomplish them are prioritized in the financial plan components. One of the four Major City Goals established in conjunction with the 2017-19 Financial Plan focuses on improving Multi-modal Transportation—specifically, to prioritize implementation of the Bicycle Transportation Plan, pedestrian safety improvements, and the Short-Range Transit Plan. Vision Zero – The message of Vision Zero—adopted as policy by the San Luis Obispo City Council in 2016—is simple: one death on our city streets is too many. Rather than accepting traffic-related deaths as “accidents” and singularly faulting road users, the Vision Zero initiative places the core responsibility for traffic safety on proper street system design, enforcement and public education. The premise is that humans are fallible and will make mistakes—properly designed transportation systems can help minimize the consequences and severity of these mistakes when they do occur. Through data-driven analysis, innovative street improvements, strategic traffic enforcement and education, the City of San Luis Obispo is committed towards a goal of zero traffic-related deaths or severe injuries by 2030. A key focus of the City’s Vision Zero initiative is to prioritize safety improvements for locations with higher potential for collisions involving vulnerable road users, such as bicyclists, pedestrians, small children, the elderly and those with disabilities. WHAT IS A BICYCLE BOULEVARD? A “bicycle boulevard” is shared roadway that creates an attractive, convenient, and comfortable bicycling environment that is welcoming to cyclists of all ages and skill levels. The low-speed/traffic environment created by bicycle boulevards is not only attractive to bicyclists, but also to pedestrians. Bicycle boulevards are designated and designed to shift priority from vehicles to bicycles. Bicycle boulevards can be designed at different levels depending on the context of the street, and the effects desired by the community. The levels range from basic treatments, such as simple striping and signage, to more significant design elements, such as diverters and closures to reduce vehicle speeds/volumes and improve the safety and comfort of the bicycling environment. Many of the treatments associated with bicycle boulevards not only benefit people on bicycles, but also help create and maintain “quiet” streets that benefit residents and improve safety for all road users.
Anholm Bikeway Plan I. Introduction 9 February 2018 Safe Routes to School Plan for Bishop’s Peak & Pacheco Elementary Schools – In August of 2017, City Council adopted a Safe Routes to School (SRTS) Improvements Plan for Bishop’s Peak and Pacheco Elementary, two schools located in the northern portion of the City. The purpose of the SRTS Plan was to identify specific transportation improvements, education, outreach and enforcement strategies to make walking and bicycling to Bishop’s Peak and Pacheco Elementary Schools safe, accessible, and attractive options for children and their families. While the SRTS Plan is separate from this effort, what it envisions is complementary to this plan to improve conditions for pedestrians and cyclists of all ages and ability levels from the downtown to the Anholm District and other neighborhoods to the north. Two of the highest priority projects included in the SRTS Plan provide significant benefits to pedestrian and bicycle mobility by continuing the connection between the route developed in this plan (Anholm Bikeway Plan) and the neighborhoods north of Foothill Boulevard: Foothill Boulevard & Ferrini Road Crossing Enhancement – Addition of a controlled pedestrian/bicycle crossing on Foothill Boulevard at Ferrini. Improvements feature addition of a high visibility crossing markings, warning signage, and installation of a Pedestrian Hybrid Beacon (a.k.a. “HAWK”) at this intersection to provide a dedicated crossing phase for cyclists and pedestrians. Where warrants prevent the installation of standard traffic signals, the pedestrian hybrid beacon provides an alternative that provides a controlled crossing phase for pedestrians and bicyclists, but stops road traffic only as needed. Ramona Drive to Foothill Boulevard Class I Path – This project is aimed at addressing the difficult walking and bicycling environment along Ramona and Foothill due to high traffic volumes and speeds. Limited bicycle accommodations at the Foothill/Broad intersection and lack of other controlled crossings along Foothill further impact connectivity between the neighborhoods north and south of Foothill. The proposed improvements include construction of a Class I Bicycle/Pedestrian Path along the eastern edge of the Church of Jesus Christ of Latter-Day Saints (LDS) property between Ramona and Foothill. This will provide a low-volume/low-stress alternative to Broad and Foothill. At the north end, this path will align with the enhanced crossing proposed at Foothill & Ferrini. Implementation of this project would require an agreement between the City and LDS Church for an access easement or right-of-way acquisition. Potential Class I Bicycle/Pedestrian Path Between Foothill and Ramona Potential Pedestrian Hybrid Beacon (HAWK) at Foothill & Ferrini
Anholm Bikeway Plan II. Project Description 10 February 2018 II. Project Description A variety of route alignments and design features were considered in developing the final concept for the Anholm Bikeway. The final recommended project includes the following primary features: Route Alignment: Starting from Monterey Street (Mission Plaza) at the south end, the designated route follows Chorro Street north to Mission Street; Mission Street west from Chorro to Broad Street; Broad Street from Mission north to Ramona Drive; Ramona Drive west to a proposed SRTS Class I Pedestrian/Bicycle Path, then north to connect with a planned enhanced bicycle/pedestrian crossing at the Foothill Boulevard/Ferrini Drive intersection. The alignment of the designated route is intended to maintain a convenient, direct path for bicyclists and pedestrians, while avoiding the steeper uphill grades on Broad (south of Mission) and Chorro (north of Mission). Bicycle Facilities: The Plan includes addition of protected bike lanes, shared lane markings, route signage and traffic calming elements between Downtown and Ramona Drive, and a dedicated SRTS Class I Bicycle/Pedestrian Path from Ramona to Foothill Boulevard to complete the continuous low-stress bicycle and pedestrian corridor. Protected bike lanes place a physical barrier between drivers and bike riders to improve safety and comfort for cyclists—particularly for less experienced riders and for the many people who are interested in biking more, but have concerns about the safety of sharing the road with busy motor vehicle traffic. For segments of the route without protected bike lanes, elements such as traffic calming, enhanced pavement markings and signage are proposed to clearly communicate that these street segments are prioritized for lower-speed bicycle travel. Traffic Calming: Traffic calming measures are proposed along the bikeway corridor to address speeding issues that currently exist. Potential measures to be considered include, but are not limited to, speed humps/cushions, raised intersections, neighborhood traffic circles, and bulbouts. The intent of these measures is to reduce motor vehicle speeds to a range consistent with the posted speed limits of these streets (25 mph or less) and to a level more conducive to a walkable, bikeable and livable residential neighborhood. Crossing Enhancements: Crossing enhancements are proposed at several intersections to improve access, safety and comfort for pedestrians, bicyclists and drivers. Crossing enhancements include installation of accessible curb ramps, high-visibility crosswalk markings and corner bulbouts. Other Features: Other important features of the proposed project include street lighting enhancements, sidewalk improvements, streetscape enhancements and green street elements, where feasible, to improve stormwater management within the study area. Figure 3 summarizes the project route alignment and key features, while Figure 4 shows the typical street cross sections along the route. Specific design elements are discussed in further detail below and analysis of the project’s advantages and trade-offs is included in Section III of this document.

Anholm Bikeway Plan II. Project Description 15 February 2018 Design Elements The project includes a suite of mobility and safety tools that benefit various road users. Key elements of the project are summarized in Table 2 below, while detailed design features are shown on the plan sheets in Appendix A. Table 2: Project Design Elements Design Element Description Benefits Mode Affected Location SIGNAGE Signs create the basic elements of a priority bikeway. Types of signage often include standard lane/route signs, branded gateway or trailblazer signs, and wayfinding signage to guide users to key destinations and other bicycle routes. Helps brand street segment to differentiate from other streets and reinforce the message of priority for bicycles along a given route. Bicyclists Pedestrians Applied at major street crossings, entry points to the bikeway and at key junctions with other bicycle routes HIGH-VISIBILITY CROSSING STRIPING & SIGNS “Ladder” crosswalk striping, dashed bike lanes or shared lane markings through intersections, and other forms of high-visibility striping and signage. Improves visibility of crossings to all roadway users. Can improve driver yield rates compared to standard crossing markings. Bicyclists Pedestrians Motor Vehicles Applied at major street crossings along the designated project corridor, such as Broad/Ramona, Chorro/Walnut, Chorro/Lincoln. GREEN PAINT Green roadway surface coloring to mark merging zones and potential conflict areas between bicycles and other roadway users. Can also be used as backing for sharrows and within intersection crossing markings for bicyclists. Increases visibility of bicycle facilities. Alerts drivers and bicyclists to potential conflict areas. Provides branding and wayfinding for cyclists along priority bicycle routes. Bicyclists Motor Vehicles Applied within bicycle-vehicle conflict areas through key intersections. Green backed sharrows provided along shared street segments to indicate priority for bicyclists. Installed at entry points to protected bikeways to prevent accidental motor vehicle entry.
Anholm Bikeway Plan II. Project Description 16 February 2018 Table 2: Project Design Elements Design Element Description Benefits Mode Affected Location PROTECTED BIKE LANES On-street bikeway with physical separation from motor vehicle traffic and distinct from the sidewalk. May be one-way or two-way, and may be at street level or sidewalk level. Physical separation can be provided through a variety of design features, including raised curbs, on-street parking, delineator posts, bollards or planters. Creates a physical barrier between bicycles and motor vehicle traffic lanes. Provides the safety and comfort of off-street bicycle path with the on-street infrastructure and connectivity of a bike lane. Removes slower-moving cyclists from auto travel lanes, simplifying conditions for drivers. Bicyclists Motor Vehicles Proposed along street segments where high vehicle speeds/volumes create a high-stress environment for bicyclists. Proposed Segments: Chorro – Palm to Lincoln Ramona – Broad to Class I Path CURB EXTENSIONS (BULB-OUTS) Extension of the sidewalk or curb face into the parking lane at an intersection or mid-block location. Reduces crossing distance and exposure area for pedestrians crossing at intersections. Provides better visibility between pedestrians and motorists. Potential to calm traffic and reduce vehicle turning speeds. Provides area for potential streetscape and/or green street enhancements. Pedestrians Proposed at Broad/Ramona, Broad/Meinecke, Chorro/Walnut. Potential for other locations along route between Lincoln and Ramona. RAISED INTERSECTIONS Raised intersections are flush with the sidewalk, like an extended speed hump, and ensure that drivers traverse the crossing slowly. Reinforce slow speeds and encourage motorists to yield to pedestrians crossing the intersection. Potential to incorporate stormwater improvements as part of intersection reconstruction. Bicyclists Pedestrians Motor Vehicles To be considered along route between Lincoln and Ramon
Anholm Bikeway Plan II. Project Description 17 February 2018 Table 2: Project Design Elements Design Element Description Benefits Mode Affected Location STREET LIGHTING Well-designed street lighting provides a continuous, sufficiently lit pathway for motorists, bicyclists and pedestrians. Improves nighttime visibility for all road users and provides perceived safety benefits for neighbors. Bicyclists Pedestrians Motor Vehicles Proposed along Chorro, Broad and Ramona where existing street light spacing does not meet City Engineering Standards. SPEED HUMPS / CUSHIONS Speed humps are traffic calming devices that use vertical deflection (typically 2-4 inches high) to slow motor vehicle traffic. Variations include speed cushions, which include cutouts specifically designed to allow wide-axle emergency vehicles to pass through unimpeded. Provides traffic calming benefits, which enhances neighborhood quality and improves safety for all users. Speed cushions reduces motor vehicle speeds with little impact to emergency vehicles or bicyclists. Bicyclists Pedestrians Motor Vehicles To be considered along route between Lincoln and Ramona. SIDEWALK IMPROVEMENTS & ACCESSIBLE CURB RAMPS Safe, accessible, continuous, and well-maintained sidewalks and curb ramps are necessary to provide an environment that encourages walking for people of all ages and abilities. Improves accessibility and connectivity for pedestrians of all ages and ability levels. Pedestrians ADA-compliant curb ramps proposed at several intersections along Broad and Chorro Streets where currently missing. Sidewalk installation proposed along west side of Broad Street where currently missing. GREEN STREET ELEMENTS Green streets incorporate a variety of design elements, such as street trees, permeable pavements, bioswales or other landscaping and plantings that improve stormwater management. Provides benefits such as improved drainage, filtering of stormwater runoff, reduced heat island effect and a more pleasant and visually appealing environment for walking and biking. Pedestrians Within widened sidewalks, corner bulbouts and to be considered within raised median as part of long-term protected bikeway separation.
Anholm Bikeway Plan II. Project Description 18 February 2018 Chorro Undercrossing Safety & Placemaking Enhancements As part of the community outreach process for this project, staff received several requests from residents for safety improvements along the Chorro Street undercrossing of Highway 101. Although this location serves as a key gateway into Downtown San Luis Obispo, the underpass currently lacks lighting or other amenities needed to provide a comfortable, attractive environment for pedestrians and cyclists at night. This plan recommends installation of safety lighting and potential streetscape improvements to enhance the pedestrian environment under the highway. If construction of these improvements is not feasible as part of Anholm Bikeway Plan implementation—which is possible considering the required costs, design challenges, and need for Caltrans approval/participation for work within the State right-of-way—these improvements could potentially be designed and constructed as part of another City program, such as the newly-created New Streetlight Installation Program, or as a stand-alone capital improvement project. The Chorro/Highway 101 underpass lacks lighting and other amenities necessary to provide a quality pedestrian environment. Pedestrian lighting and streetscape enhancements are recommended to improve pedestrian conditions at this key gateway point to Downtown San Luis Obispo.
Anholm Bikeway Plan II. Project Description19 February 2018 Bicycle and Pedestrian Intersection Crossing Enhancements The proposed project includes focused improvements at several intersections to provide wayfinding guidance for cyclists, and to improve crossing safety for pedestrians and bicyclists. Recommended treatments include green pavement markings within potential vehicle-bicycle conflict areas, directional pavement markings to convey the path for bicyclists to follow when entering/exiting the two-way protected bikeway on Ramona, corner bulbouts to shorten crossing exposure for pedestrians, and high-visibility crosswalk markings to improve driver awareness of pedestrians at key crossing locations. Improvements are recommended at Chorro/Walnut to improve crossing safety for bicyclists and pedestrians. Bulbouts, widened sidewalks, high-vis crosswalk markings and other pedestrian improvements at Broad/Meinecke/Ramona
Anholm Bikeway Plan II. Project Description20 February 2018 Why Protected Bike Lanes? As mentioned previously, the City has established goals to increase mode share for alternative forms of transportation, including goals to increase bicycle mode share from current levels (6-8%) to 20%. Many community benefits are achieved by increasing mode share for active forms of transportation (walking and biking), from benefits to community health with increased physical activity, to contributions towards reducing parking demand, traffic congestion, fuel consumption and greenhouse gas emissions. To achieve these mode shift goals, it is important to first understand existing travel behavior within the community and the primary barriers that prevent residents, employees and visitors from bicycling more often. Regardless of whether actual bicycle collisions have occurred on a given street, surveys show that the perception of risk or unsafe conditions is often the most significant barrier to bicycling for the majority of San Luis Obispo residents. For the purposes of bicycle system planning, the general population of a community can be classified into four types of transportation bicyclists. These four types of users and the corresponding percent of City of San Luis Obispo residents who identify with each classification, as estimated based on local travel survey data, are summarized in Figure 5.4 As shown in Figure 5, 18% of San Luis Obispo residents fall within the “No Way No How” category—they do not currently bicycle and have little interest in doing so. Similarly, 18% fit the “Strong and Fearless” description, and will likely bike regardless of what facilities are provided. The remaining 64% of residents fall into the “Enthusiastic and Confident” or “Interested but Concerned” categories—less experienced riders who are interested in bicycling for transportation, but do not feel comfortable riding in mixed traffic on most streets, or even within striped bike lanes on busier streets. Not all bicycle facilities are created equal—a painted line dividing cyclists from busy motor vehicle lanes, or sharrows placed within a travel lane on a high-traffic/speed street might be acceptable for “Strong and Fearless” riders, and perhaps some “Enthusiastic and Confident” cyclists. However, the remaining people interested in cycling—somewhere between 31% and 64% of city residents—will generally choose to drive if the type of low-stress bike facilities that they feel safe using—separated and protected bikeways—are not available. If the City is to meet its goal to reach 20% bicycle mode share, it stands to reason that strategic investments should be made in the types of bicycle infrastructure—facilities with physical separation from cars—that have potential to not only benefit the existing rider population, but expand it significantly by attracting the “Enthusiastic and Confident” and “Interested but Concerned” riders. While protected bike lanes—also commonly referred to as “cycle tracks” or Class IV Bikeways (per Caltrans standard bikeway classification)—are a new type of facility for the City of San Luis Obispo, their benefits in terms of safety and potential to increase bicycle ridership are well-documented. Protected bike lanes have been a best practice in street planning for decades in many European cities, such as 4 Source: 2013 Bicycle Use Survey Results, San Luis Obispo Council of Governments (SLOCOG), October 2013.
Anholm Bikeway Plan II. Project Description 21 February 2018 Amsterdam and Copenhagen, where 40 percent or more of citywide trips are made by bicycle. Over the past decade, more and more North American cities have been building these types of facilities, with over 400 protected bike lane installations in over 100 U.S. cities as of 2017. Why are more and more cities building protected bike lanes? The following statistics provide some explanation:5 Increased Bicycle Ridership – New protected bike lanes have been found to boost bike volumes by an average of 75 percent in the first year alone. Following the City of Calgary’s recent rollout of a four-mile network of protected bike lanes as a pilot project, bicycle ridership along these routes doubled in the first three months, including a 30 percent increase in female riders. Throughout the downtown, bicycle ridership increased by 40 percent during the pilot project. Attractive to Less Experienced Riders – Surveys find that 80% or more of “Interested but Concerned” bicyclists would be comfortable riding in protected bike lanes—a significantly higher percent compared to those who would be comfortable riding in standard bike lanes (39%) or streets with no bicycle facilities (8%). They Can Make Biking Safer – Installing a protected bike lane on a street cuts the injury risk per bike trip by 30 percent (two-way bikeway) to 50 percent or more (one-way bikeway). Reduces Some Types Unsafe Behavior – Adding a protected bike lane cuts sidewalk riding by 56 percent on average (sidewalk and wrong-way riding accounts for 16 percent of San Luis Obispo bicycle collisions). Pedestrian Safety – Protected bike lanes can calm traffic and reduce crossing distances for pedestrians. With the installation of protected bike lanes along several streets, New York City reported a reduction in traffic injury rates—mostly reflective of pedestrian injuries—of 12 to 52 percent. The Plan includes installation of protected bikeways at two locations. The buffered bike lanes on both sides of Chorro Street south of Lincoln and proposed for ultimate conversion to protected bike lanes, and a two-way protected bikeway is planned to replace on-street parking on the north side of Ramona between Broad and the planned SRTS Class I Path. 5 Statistics referenced from People For Bikes (www.peopleforbikes.org) and The Green Lane Project (www.greenlaneproject.org).

Anholm Bikeway Plan II. Project Description 22 February 2018 Future Components There are several improvements that have been requested by the community, presented in other plans, or recommended by staff that relate to the Anholm Bikeway Plan, but due to costs or other constraints, are not recommended at this time. These improvements may be studied further and potentially implemented in the future as part of other City programs or as stand-alone projects. These include the following: Closure of Highway 101/Broad Street Ramps & Grade-Separated Pedestrian/Bicycle Crossing of Highway 101 – As discussed previously, the project description for the Broad Street Bicycle Boulevard in the 2013 BTP identifies a future grade-separated bicycle/pedestrian crossing of Highway 101 at Broad Street. Implementation of this crossing will require the ultimate closure of the Broad Street ramps by Caltrans, which according to recent studies by the City and Caltrans will not be feasible for the foreseeable future due to resulting impacts to the adjacent interchange at Santa Rosa (Highway 1) and nearby city streets. Major improvements would be needed to address the anticipated impacts at the Santa Rosa (Highway 1) interchange—due to the significant costs associated with these improvements, this is not feasible at this time. In addition, construction of a new grade-separated crossing of Highway 101 at Broad Street—most likely a bridge over the highway—would involve significant costs (estimated at several million dollars in the 2013 BTP), which further limits the feasibility of these improvements at this time. Since the southern portion of the Anholm Bikeway alignment follows Chorro Street into Downtown, including installation of protected bike lanes along this stretch, the ultimate utility and need for a new crossing at Broad Street and Highway 101 is likely reduced. This improvement is not included as part of the Anholm Bikeway Plan at this time, but the City will continue to work with Caltrans to pursue closure of the Broad Street ramps, and will reevaluate the potential for a pedestrian/bicycle crossing at this location in future years if closure of the ramps becomes feasible. Safety Improvements at Chorro & Peach Intersection – The intersection of Chorro and Peach has been identified as a high collision-rate intersection in the City’s annual Traffic Safety Report in several recent years, with a propensity for auto vs. auto broadside collisions due to unsafe east/west turning and through movements from Peach Street onto Broad Street. Several potential safety improvements have been evaluated for this location, such as relocation of a utility pole that impacts sight distance for drivers, installation of a neighborhood traffic circle, or turn restrictions, but due to the challenging constraints at this intersection, improvements have yet to be implemented. While the Anholm Bikeway Plan proposes striping improvements and accessible curb ramps to enhance bicycle and pedestrian crossing safety this intersection, more substantial improvements will need to be implemented as part another program—likely through the City’s Traffic Safety (Vision Zero) program. Gateway Treatments – Ideally, the Anholm Bikeway will serve as a key bicycle and pedestrian gateway into Downtown San Luis Obispo—for residents, students, workers and visitors. With the many proposed downtown revitalization strategies envisioned in the recently-approved Downtown Concept Plan and Mission Plaza Concept Plan, there will likely be additional interest and support for enhancing this northern gateway into Downtown. While not evaluated in detail or included in the project designs or cost estimates as part of the Anholm Bikeway Plan, it is recommended that additional gateway landmarks, such as attractive entry signage and artwork, or a bicycle/pedestrian count display be considered as part of future improvements to further formalize the Anholm Bikeway corridor and visually communicate the importance of this route as a priority street for multimodal travel.Count Totems display real-time bicycle and pedestrian volumes along gateway points to key routes. Displays can be customized and configured to show cumulative totals over the course of a year towards a year-end target. The 2013 City Bicycle Transportation Plan envisions a future grade-separated bicycle and pedestrian crossing of Highway 101 at Broad Street. This improvement is not feasible currently and will not be considered until closure of the Broad Street/Highway 101 Ramps by Caltrans.
Anholm Bikeway Plan III. Analysis of the Project 23 February 2018 III. Analysis of the Project Traffic Access & Circulation The City evaluates vehicular traffic impacts based on roadway segment and intersection congestion/delays as measured using auto Levels of Service (LOS)6, as well as using established maximum daily traffic volume thresholds for residential streets to assess traffic impacts to neighborhood quality of life. For the purposes of assessing potential traffic impacts in conjunction with the Anholm Bikeway project, convenience of property access, collision trends, and potential impacts to emergency services are also considered. To guide this analysis, traffic data was collected in 2016 and 2017, including intersection and roadway volumes (autos, pedestrians and bicycles), speed survey data and collision reports for the most readily available five-year period. Existing traffic data and detailed traffic analysis findings are summarized in Appendix B. Roadway Segment and Intersection Levels of Service The Recommended Project does not include any features that modify traffic circulation, access or emergency vehicle operations, and is expected to have a negligible impact on vehicular traffic capacity/throughput. For these reasons, roadway segment and intersection operations are anticipated to remain similar to existing conditions. The City has adopted an automobile level of service performance target of LOS D or better for streets affected by the proposed project. For reference purposes, AM and PM peak hour traffic operations were reviewed at intersections and roadway segments along the proposed bikeway route—all study facilities currently operate at acceptable LOS. Neighborhood Traffic The City evaluates potential neighborhood traffic impacts by comparing Average Daily Traffic (ADT) volumes and speeds along residential streets with the corresponding maximum ADT and speed targets established in the City General Plan Circulation Element.7 A proposed project would potentially trigger a neighborhood traffic impact if it would cause residential street traffic volumes or speeds to exceed these established thresholds, or if the project further increases traffic volumes on a street that already exceeds the maximum thresholds under existing conditions. As shown in Table 3, existing traffic levels on Chorro and Lincoln Streets exceed established neighborhood traffic volume thresholds. Prevailing speeds on Broad, Chorro and Lincoln Street exceed established maximum neighborhood traffic speed thresholds. The proposed project is not expected to trigger any new neighborhood traffic impacts, but has potential to reduce speeds below max thresholds along Chorro and Broad Street with the traffic calming measures proposed in this plan. 6 Level of Service (LOS) is a standard qualitative measure used to describe traffic conditions in terms of speed, travel time, delays and driver convenience. LOS is defined using letter grades “A” through “F”, with LOS A representing free-flow conditions, and LOS F representing heavy congestion with traffic demands exceeding capacity. 7 City General Plan Maximum ADT Targets: Local Streets (1,500 veh/day); Residential Collectors (3,000 veh/day), except Broad/Chorro north of Lincoln and Margarita (5,000 veh/day). Desired maximum speeds for residential streets are 25 mph.

Anholm Bikeway Plan III. Analysis of the Project24 February 2018 Driveway Access The proposed project is not expected to affect the ability of drivers to ingress or egress private driveways or intersections along the proposed bikeway route. However, there are best practices and suggested design details for enhancing locations where protected bikeways cross driveways and intersections to increase visibility for drivers and bicyclists through these conflict areas. Potential strategies include installation of enhanced pavement markings, green pavement coloring and warning signage. Figure 6 below illustrates some example treatments for intersection and driveway areas that are proposed to be implemented along the bikeway. Figure 6: Typical Driveway and Intersection Treatments Openings in protected bikeway physical separation will be provided at driveways and intersections to allow vehicles to ingress and egress. Bikeway buffer provides clear area for residents to place waste bins for curbside collection without obstructing bikeway or auto travel lanes.Openings in protected bikeway barrier provided at driveways and intersections to allow sufficient space for drivers to enter and exit Proposed bikeway buffer (2.5’-3’ wide) provides convenient area for placing waste bins for collection. Buffer width accommodates typical residential bin sizeWhere protected bikeways cross higher-volume driveways, such as along Ramona Drive where the proposed two-way protected bikeway crosses the Foothill Plaza commercial driveway, enhanced design treatments shall be used to increase visibility of this conflict area for drivers and cyclists. Potential treatments include enhanced pavement markings, green colored pavement, warning signage and provision of clear sight lines from all approaches.
Anholm Bikeway Plan III. Analysis of the Project25 February 2018 Parking Considerations Potential parking concerns related to the Plan are evaluated by analyzing on-street parking supply and demand with and without the parking removal proposed by the project along Ramona Drive. Although the final number of on-street parking spaces impacted by the project may change slightly with final design, based on review of preliminary concepts, on-street parking loss is estimated as follows: Ramona Drive – 17 spaces removed on north side from Broad to proposed SRTS Class I Path to provide two-wayprotected bikeway and pedestrian/bicycle access to the path.It should be noted that the street parking along this segment of Ramona fronts a commercial shopping center and a senior living facility—both of are fully parked on-site per City requirements. The current parking demand along this segment of Ramona predominantly reflects spillover from a nearby student apartment complex and regular use of Ramona Drive as a pseudo park-and-ride lot by university students who park here and take the nearby bus service to Cal Poly. To better understand existing on-street parking conditions near these street segments, parking surveys were conducted in fall of 2017 for various days of the week and times of day during a period when local schools and Cal Poly were in session. Parking surveys included inventory of existing on-street parking supply and occupancy during various times of day throughout the vicinity of the proposed Anholm Bikeway. Parking surveys found late evening on a weeknight (12-2 AM) to be the period where on-street parking demand is typically highest—both along Chorro, Broad and Ramona, as well as within the surrounding neighborhood. This peak period was used as a baseline for evaluating project-related parking impacts. See Appendix B for detailed parking occupancy data. Existing parking conditions are mapped visually in Figure 7, with street segments color-coded based on percent occupancy and labels showing the number of available parking spaces on each block. Street segments are highlighted red where peak occupancy exceeds 85%. A parking occupancy rate of 85%-90% is typically considered the “practical capacity” of a street, meaning that there could be a few on-street parking spaces available, but drivers may have a difficult time finding them. When parking demand exceeds the practical capacity, this can lead to drivers “cruising” around the block and increases temptation to park illegally, which could impact neighborhood quality for residents. Because the segment of Ramona where parking removal is proposed is near 100% occupancy currently, parking removal is anticipated to create a deficit of 13 spaces. The displaced parking demand of 13 spaces is likely to shift to the nearby streets during peak periods—most likely Broad, Meinecke and further west on Ramona. As shown in Figure 7, there is generally available on-street parking along these nearby streets to accommodate this shift. However, street parking demand is already a sensitive topic within this neighborhood, with increasing concerns related to the upcoming construction of two new multifamily residential developments in the area. Residents have already expressed interest in pursuing implementation of a residential parking district within the Anholm neighborhood to better manage parking demand. Residential parking districts help manage excess on-street parking demand by requiring a city-issued parking
Anholm Bikeway Plan III. Analysis of the Project 26 February 2018 permit to park on-street during designated hours. A limit of two permits are made available to the property owners or residents of each home within the established district. Vehicles parked on street without a permit in these areas are subject to citation. The City is supportive of this effort and will assist with initiating the process for developing a district if sufficient support exists within the neighborhood. Benefits to Bicycling As mentioned in the Purpose and Need section, and as illustrated in Figure 2, existing traffic volumes and speeds along Broad and Chorro Streets exceed the levels recommended for mixed-flow conditions, where bicyclists and motor vehicles share travel lanes. While some bicyclists are comfortable riding under these conditions—over 300 bicyclists per day travel Broad, Chorro or Lincoln Streets between downtown and Foothill Boulevard—these conditions do not provide the type of bicycling environment conducive to attracting new riders of all ages and ability levels, which is needed to achieve the City’s bicycle mode share objectives. Specific features of the Recommended Project that are expected to contribute to a high-quality, low-stress bicycling environment include: Protected Bike Lanes – Existing buffered bike lanes on Chorro are planned to be extended between Palm to Lincoln, with potential for physical separation in the future. A two-way protected bikeway is proposed on Ramona from Broad to the planned SRTS Class I Bicycle/Pedestrian Path by removing on-street parking on the north side of Ramona. Safe Routes to School Class I Path – A Class I Bicycle/Pedestrian Path is proposed between Ramona and Foothill, completing the continuous low-stress bicycle connection between downtown and Foothill Boulevard. The new path will align with the planned SRTS bicycle/pedestrian crossing at Foothill & Ferrini, linking the Anholm Bikeway with the neighborhoods and destinations north of Foothill, including Bishop’s Peak and Pacheco Elementary Schools and Cal Poly. It should be noted that completion of this path is contingent on the City establishing an easement or right-of-way agreement with the LDS Church. Branded Route Signage & Pavement Markings – Bicycle route signs and pavement markings are proposed at entry points to the Anholm Bikeway and along the route to provide wayfinding for cyclists and to brand the route as a priority bicycle street. Dashed roadway centerlines are proposed along Broad Street to allow drivers to safely (and legally) pass cyclists. High-Visibility Crossing Markings & Green Paint – High-visibility crossing markings and green paint are proposed through key intersection crossings to help bicyclists navigate the designated Anholm Bikeway route and to increase visibility of bicycle-vehicle conflict areas. Traffic Calming Elements – Traffic calming elements are proposed along the bikeway route between Lincoln and Ramona to reduce speeding and improve conditions on segments where bicyclists and motor vehicles share travel lanes. Traffic calming elements provide the secondary benefit of improving safety for pedestrians and neighborhood quality for residents. Potential features may include, but are not limited to, replacement of the existing speed humps on Broad Street north of Mission with new speed cushions, corner bulbouts, raised intersections, neighborhood traffic circles or other features. Development of traffic calming strategies along this route segment will be refined further with input from the community prior to implementation. To evaluate the bicycling environment along the Anholm Bikeway, a bicycle Level of Traffic Stress (LTS)8 analysis was conducted for street segments along the proposed corridor. “Traffic stress” is the perceived sense of danger associated with riding in or adjacent to vehicular traffic and is one of the greatest deterrents to bicycling. A bicycle LTS analysis is an objective, data-driven approach to evaluating bikeways that correlates measurable factors such as roadway design, traffic volumes and motor vehicle speeds to typical bicyclist perceptions of comfort and willingness to use a given facility. LTS scoring is designed to correspond with the “Four types of Bicyclists” categories (referenced previously in Figure 5), with a range of LTS 1 to LTS 4 representing conditions from lowest stress (LTS 1) to highest stress (LTS 4). In general, bikeways are considered low stress where there is little interaction between cyclists and motor vehicles (i.e. a shared low-volume/speed local street), or where greater degrees of 8 LTS analysis applied using methodology developed by the Mineta Transportation Institute Report II‐19: Low‐Stress Bicycling and Network Connectivity (2012).
Anholm Bikeway Plan III. Analysis of the Project 27 February 2018 physical separation are provided between a bikeway and motor vehicle traffic (i.e. protected bike lanes or off-street path). LTS scores are defined in Table 4 below, while LTS scores are mapped for the proposed Anholm Bikeway route in Figure 8 for conditions with and without the proposed project. Table 4: Level of Traffic Stress (LTS) Definitions and Types of Bicyclists
Anholm Bikeway Plan III. Analysis of the Project 28 February 2018 Figure 8: Level of Traffic Stress Map with and without Project As shown above, under existing (“No Build”) conditions, most of the proposed bikeway route scores as LTS 3 or LTS 4—the higher levels of traffic stress. These streets will likely be comfortable advanced and experienced adult cyclists, presenting an intimidating environment for children and less-experienced adult cyclists. With ultimate implementation of the proposed project improvements, a significant portion of the Anholm Bikeway route will provide options with route scores at LTS 1 or LTS 2, which proves a low-stress bicycling environment that should appeal to “interested but concerned” riders and many young or inexperienced cyclists. The stretch of Chorro Street between Lincoln and Mission, where traffic volumes exceed 6,000 vehicles per day, will continue to score as LTS 4, even with the addition of traffic calming measures. Similarly, the segment of Chorro between Downtown and Lincoln will remain at LTS 3 until the potential ultimate conversion of buffered bike lanes to protected facilities. The EXISTING CONDITIONSPROJECT CONDITIONSTypes of Bicyclists in San Luis Obispo Strong and Fearless (18%) – Willing to ride a bicycle on any roadway regardless of traffic conditions. Comfortable taking the lane and riding in a vehicular manner on major streets without designated bicycle facilities. Enthusiastic and Confident (33%) – Bicyclists who are comfortable sharing the roadway with automotive traffic in some instances, but prefer to ride in their own designated bike lane or off-street facility. Interested but Concerned (31%) – Infrequent bicyclists with some inclination towards bicycling more regularly if they felt safer on the roadways. Not very comfortable sharing the road with cars, or riding on major streets, even with a bike lane. Prefer separated pathways or low-traffic neighborhood streets. No Way No How (18%) – Residents who simply aren’t interested in bicycling, for reasons of topography, inability, or simply complete and utter lack of interest. Unlikely to adopt bicycling in any way. Segment remains at LTS 3 until ultimate installation of physical separation
Anholm Bikeway Plan III. Analysis of the Project 29 February 2018 addition of traffic calming measures and a dashed centerline along Broad Street is anticipated to improve conditions to LTS 2 along this segment; however, volumes on Broad Street will continue to exceed the levels recommended for a shared street environment, as shown previously in Figure 2. As discussed in the implementation section of this plan (Section V), further bicycle facility improvements may be considered in later project phases for the route segment between Lincoln and Ramona if performance monitoring studies indicate a need for further bikeway enhancements. Any future modifications to the plans for these segments would require approval by the City Council. Benefits to Pedestrian & Streetscape Environment Connectivity, accessibility, safety and comfort are all important components of a quality pedestrian environment. While many of the primary features of the Anholm Bikeway project focus on improving conditions for bicyclists, the recommended project designs also include substantial elements to improve the quality of the pedestrian environment between downtown and Foothill Boulevard. The project includes the following features to improve the pedestrian environment: Elimination of Sidewalk Gaps – The project recommends installation of sidewalks along Broad where gaps currently exist in the pedestrian network, particularly on the west side of Broad Street. Accessible Curb Ramps – ADA-compliant curb ramps are currently lacking at several intersections along Broad and Chorro Streets. The project includes construction of new ADA curb ramps at each intersection along the designated route where they are currently lacking. Intersection Crossing Enhancements – The project includes elements intended to improve pedestrian crossing safety and comfort at intersections. High-visibility crosswalk markings are recommended at key crossing locations, such as Chorro & Lincoln and Broad & Ramona. Corner bulbouts are proposed at several intersections along the Anholm Bikeway route, including at Chorro & Walnut, Broad & Meinecke, and Broad & Ramona. Bulbouts provide several benefits to pedestrian safety and comfort, including potential to slow motor vehicle turning speeds, shorten pedestrian crossing distances and increase visibility of pedestrians waiting to cross. Potential for Streetscape Enhancements and Green Street Elements – The project includes potential to improve the streetscape aesthetics and incorporate green street elements at several locations. Locations where corner bulbouts are proposed, such as at Broad & Ramona and Broad & Meinecke, there will be additional sidewalk area available to incorporate landscaping and/or drainage improvements to reduce demand on the stormwater system during rain events, which is particularly important considering the proximity of Brizzolara and Old Garden Creeks. Where protected The Recommended Project provides opportunities for streetscape and green street enhancements to beautify the corridor and improve stormwater management benefits during rainy seasons. Design elements considered as part of the project include landscaped corner bulbouts, and bioswales within widened sidewalks and within the potential long-term raised median separating the protected bikeways from motor vehicle traffic.
Anholm Bikeway Plan III. Analysis of the Project 30 February 2018 bike lanes are proposed, physical separation may include features like planter boxes or landscaping strips that not only provide physical separation from motor vehicle traffic, but provide opportunities to further beautify the Anholm Neighborhood, where attractive landscaping and lush, well-maintained gardens are commonplace. Buffer from Motor Vehicle Traffic – The protected bike lanes proposed for Chorro and Ramona have potential to improve not only the bicycling environment, but the pedestrian environment as well. Protected bike lanes create a continuous buffer between sidewalks and motor vehicle travel lanes—a buffer that improves pedestrian comfort that can be lacking along streets where on-street parking lanes do not exist, or have low utilization. Protected bike lanes can also visually narrow the perceived roadway width for drivers, which can help reduce motor vehicle speeds. Because the potential risk for severe injury or death in pedestrian vs. motor vehicle collisions increases exponentially as vehicle speeds increase, it is important to endeavor to achieve speeds within the project study area conducive to a walkable, residential district (25 mph or less). Street Lighting – The project recommends installation of new streetlighting at the Highway 101/Chorro undercrossing, and at several locations along Broad, Chorro and Ramona where existing lighting does not meet City standards. Pedestrian-scaled street light poles are proposed for the Highway 101/Chorro undercrossing, while an additional six (6) cobra-head LED street lights are proposed to be mounted to existing power poles throughout the neighborhood so that the corridor lighting is consistent with City standards. Existing and proposed street lighting are shown in Figure 9. The risk of pedestrian fatality increases significantly when speeds exceed 30 mph.

Anholm Bikeway Plan III. Analysis of the Project 31 February 2018 Neighborhood Quality Considerations When evaluating the potential benefits and trade-offs of the Anholm Bikeway project, it is important to not only assess the effects of the project on users traveling through the planned route, but to also consider the specific effects—both positive and negative—on the neighborhood that the proposed bikeway travels through. Potential positive and negative impacts on neighborhood quality associated with the Anholm Bikeway are summarized as follows: Potential Benefits to Neighborhood Quality Traffic Volumes and Circulation Unchanged – The project includes design elements that retain existing traffic circulation and access within the Anholm neighborhood, creating little-to-no impact on vehicular through traffic, property access or emergency service response. Improved Safety Lighting – To address concerns with lack of night lighting within the Anholm neighborhood, the Recommended Project includes addition of pedestrian-scaled street lighting at the Highway 101/Chorro undercrossing, as well as addition of several energy efficient LED street lights on Chorro, Broad and Ramona to fill in the gaps in the lighting network and provide a continuously lit path that bicyclists, pedestrians and drivers can feel safe navigating at night. The new street lights will be spaced consistent with City standards for residential streets and will provide a level of illumination consistent other streetlights within the existing neighborhood. Traffic Calming – High motor vehicle traffic volumes and speeds can negatively impact the neighborhood quality along a residential street. As shown previously in the Neighborhood Traffic Assessment section (See Table 3), the proposed project includes traffic calming features to reduce speeding along several street segments. In addition, a monitoring plan will be implemented after installation of the initial project elements to observe traffic volumes and speeds within the study area to identify if additional traffic calming measures are warranted in the future. On-Street Parking Retained – The Project includes removal of some street parking along Ramona, but retains existing on-street parking fronting the residential homes on Broad and Chorro Street, which was identified as a high priority for residents of the neighborhood. Safer Passing of Cyclists – Currently, Chorro Street, Broad Street and Ramona Drive feature continuous double-yellow centerlines, which prohibit drivers from crossing into the opposing lane to pass other road users. This can lead to frustration for both motorists and bicyclists sharing the travel lanes. Motorists are inconvenienced when following slower-moving bicyclists, and bicyclists are uncomfortable getting tail gated or passed closely faster-moving traffic. The Project replaces the solid center lines with a dashed single stripe along the mixed-flow segments of the bikeway route to allow drivers to cross into the opposing lane (when safe to do so) to pass cyclists safely, courteously, and legally. Improved Walkability – The Project includes addition of accessible curb ramps, enhanced intersection crossings, reduced sidewalk gaps and other amenities to contribute to a quality walkable neighborhood environment. Benefits of a Walkable, Bikeable Neighborhood – The benefits of high-quality pedestrian and bicycle infrastructure are well-documented, from community health benefits associated with increased opportunity for physical activity, to reduced traffic congestion and improved safety for all road users. Investment in pedestrian and bicycle infrastructure has also been found to provide economic benefits for properties located within proximity of these facilities. Current studies on the economic impacts of active transportation infrastructure have found that homes in walkable neighborhoods and
Anholm Bikeway Plan III. Analysis of the Project 32 February 2018 within close proximity to high-quality separated bicycle facilities have higher sale prices on average than homes located in areas without these features. Further, corridors where protected bike lanes have been installed have seen either no change or increases in retail sales.9 Aesthetics – The residents of the historic Anholm District clearly take pride in their neighborhood, with attractive street trees, landscaping and beautiful gardens lining each street. The design of the proposed project will include elements that are intended to compliment the unique aesthetics of the existing neighborhood. Sidewalk improvements and corner bulbouts will provide potential to install additional landscaping and/or green street treatments and the City will consider the aesthetic context of the neighborhood when considering new guide signage and treatments/materials for physical separation along the protected bikeways. The City plans to install a raised concrete median within the bike lane buffers, providing the opportunity for attractive low-maintenance hardscape, or higher-maintenance planter beds, bioswales or other green street features if sufficient funds and maintenance resources are available. If there is interest among community groups or neighborhood residents, planter boxes or other landscaping areas may be considered within the bike lane separation with potential for an “adopt a planter” program where residents can apply to install and maintain their own unique plantings, including flowers or vegetables. Overall Ability to Support Project Goals & Objectives The Anholm Bikeway Plan diverges is some ways from the concept originally envisioned for this route in the 2013 BTP, as the final project does not propose a traditional bicycle boulevard or follow Broad Street exclusively. Still, the Plan supports the project goal to create a safe, low-stress route that serves bicyclists and pedestrians of all ages and skill levels connecting the City’s downtown core north to Foothill Boulevard. The specific design elements identified in this plan are generally consistent with the design objectives initially established for this project, with unique features that brand the Anholm Bikeway as a priority bicycle corridor, traffic calming measures to reduce motor vehicle speeds, features that reduce conflicts between bicyclists and motor vehicles, and elements that improve accessibility and safety for pedestrians. For the southern segment of Chorro between Downtown and Lincoln, and along Ramona west of Broad, the addition of protected bike lanes provides substantial potential to attract less confident cyclists and support the City’s mode share and sustainability goals. However, traffic volumes along much of the middle segment of the route—between Lincoln and Ramona—will remain above levels recommended for conditions where bicyclists and drivers share travel lanes. Implementation of additional traffic calming and a dashed centerline to encourage safe/legal passing of cyclists will provide some benefit to the bicycling environment on these segments, but the frequent conflicts with passing autos will likely continue to deter many “interested but concerned” riders. 9 Sources: How Much is a Point of Walk Score Worth, Redfin.com.

Anholm Bikeway Plan IV. Project Development Process 33 February 2018 IV. Project Development Process Community Outreach and Engagement Development of this plan included an extensive community-based public engagement effort, focused on understanding the key needs and priorities of residents and stakeholders. Major components of this community outreach effort include: Public Meetings Community Meetings – Four (4) community meetings were held at the City/County Library over the course of the two-year long project planning process. This process included an initial project kick-off meeting, an interactive design charrette to allow attendees to draw up their desired plans for the street improvements, a meeting to present preliminary project alternatives, and a final neighborhood meeting to present plans and invite feedback on the final recommendations for the Anholm Bikeway Plan. Informal Field Visits – In addition to formal public meetings, City Transportation Staff also conducted several in-person site visits to tour the study area and answer questions from residents, business owners and other stakeholders who may not have been able to attend prior community meetings. Staff also joined a group of Bishop’s Peak and Pacheco Elementary School parents and students for a bicycle tour following their typical routes to/from school along Broad and Chorro Streets. Bicycle Advisory Committee Meetings – The City Bicycle Advisory Committee (BAC) consists of seven members who must be residents of the City and provides oversight and policy decisions on matters related to bicycle transportation. The BAC received presentations from staff on the Broad Street Bicycle Boulevard/Anholm Bikeway Plan during the preliminary alternatives development stage, and again with submittal of the final concept plan. The BAC solicited public comments from meeting attendees and ultimately provided staff with feedback and recommendations to carry forward to the City Council. City Council Hearings – During the alternatives development stage, a City Council Study Session was held to present several design options considered for the proposed bikeway. The Study Session was well-attended and provided an opportunity for the Council and the public to learn more about the project and provide input on the benefits and trade-offs associated with various project alternatives. The Final Anholm Bikeway Plan was presented for Council consideration and adopted in February, 2018. Project Website A project website (www.peakdemocracy.com/3444) was created at the onset of this planning process and has been used throughout development of the plan to provide updates, access to project materials, and to serve as an open forum for community members to leave feedback. As of December 2017, the project website has received over 1,300 unique visitors and has 175+ comments in the online forum. In developing this plan, public outreach efforts included community meetings, in-person site tours, bike to school ride-a-longs, an interactive design charrette, and an online comment forum via the project website.
Anholm Bikeway Plan IV. Project Development Process 34 February 2018 Alternatives Development The road to the final concept plan for the Anholm Bikeway project is long and involved development and analysis of many potential project alternatives and variants. During the spring and summer of 2017, three preliminary project alternatives were presented to the community, BAC and City Council for consideration. The alternatives provided three distinct options for the most challenging portion of the bikeway between Lincoln Street and Ramona Drive, each with its own unique benefits, challenges and trade-offs. Alternatives included (Alt 1) a traditional bicycle boulevard with traffic diverters and a continuous route along Broad Street, (Alt 2) conversion of Broad and Chorro Streets to single-lane, one-way couplets to provide width for protected bike facilities, and (Alt 3) a “low-impact” alternative that included only minor route markings, signage and traffic calming elements. Each alternative was defined and analyzed in detail and the findings were shared in an Alternatives Screening Report (available on the project website). To supplement the input provided at previous community meetings and via the project’s web forum during the alternatives development process, Transportation Staff conducted surveys of residents to gauge support for any of the three proposed project alternatives and to better understand the specific features that the community liked or disliked. An online survey was made available for citywide participation via the project webpage, while a mail-in survey was distributed to approximately 1,200 residents in the Broad and Chorro neighborhood. In total, nearly 500 survey responses were received. The results of this survey, which are shown below, were presented during the City Council Study Session referenced above. Based on the survey responses, Alternative 1 (traditional bicycle boulevard with traffic diversion) received the least support both citywide and within the Broad/Chorro neighborhood. Per the online citywide survey, Alternative 2 (two-way conversion with protected bikeways) was the most popular option, receiving 44% of the total votes—nearly double that of the second ranking option. Within the neighborhood, there was not a clear consensus for a preferred option, with 37% of participants indicating that “No Project Alternative is Acceptable”, 30% of participants indicating support for Alternative 3 (markings, signage and traffic calming only), and 27% supporting Alternative 2. Upon review of the preliminary alternatives, the Alternative 2 was identified as the BAC’s preferred alternative—primarily because this alternative included protected bicycle facilities, which the group believed would provide the greatest potential to improve bicycling within the city. After reviewing the various project options and receiving input from the community at a well-attended Council Study Session, the City Council ultimately recommended that staff carry forward two variants of the preliminary alternatives for refinement. Public comments received from Anholm Neighborhood residents during the Council Study Session reflected a general theme of opposition to any project features that would impact vehicular traffic access/circulation or street parking within their neighborhood; thus, the two alternatives to be carried forward did not include features that would significantly change traffic circulation or access: Preferred Alternative – An option that includes partial removal of on-street parking on segments of Chorro and Broad Streets to provide dedicated/protected bike lanes without removing vehicular travel lanes or impacting traffic circulation. Secondary Alternative – A “low-impact” option that utilizes Lincoln Street east of Chorro and establishes a bicycle route with features such as enhanced markings, signage and minor traffic calming that can be easily implemented and does not impact street parking or traffic circulation. The final concept represented in this plan represents a hybrid, or variant of the two alternatives carried forward from the Council Study Session.Broad Street Bicycle Boulevard Project – Alternatives Analysis Community Preference Survey Results (as of 8/1/17) Community surveys were distributed both citywide and to the Anholm Neighborhood within vicinity of the proposed bikeway to gauge support for preliminary project alternatives.
Anholm Bikeway Plan V. Cost Estimates, Phasing and Performance Monitoring Strategies 35 February 2018 V. Cost Estimates, Phasing and Performance Monitoring Strategies Phasing Plan and Cost Estimates Project improvements are expected to be implemented in phases, with each series of improvements prioritized based on several factors, including overall benefit to bicycle and pedestrian safety and mobility, desire for each improvement based on community input, and costs. Planning-level cost estimates were developed for the improvements identified in each phase and are summarized in Table 5 below.

Remaining components will be implemented incrementally based on availability of future grant and CIP funds.CITY TO CONTINUE WORKING WITH CALTRANS TO PURSUE CLOSURE OF THE HIGHWAY 101/BROAD STREET RAMPS
Anholm Bikeway Plan V. Cost Estimates, Phasing and Performance Monitoring Strategies 36 February 2018 Phase 1 will include implementation of the highest-priority features at the north end of the corridor—improvements that will support safe routes for families walking and biking to Bishop’s Peak and Pacheco Elementary Schools. This includes construction of the planned bicycle/pedestrian crossing of Foothill Boulevard at Ferrini, right-of-way acquisition and construction of the Class I Bicycle/Pedestrian Path between Ramona and Foothill, and construction of the proposed two-way protected bikeway along Ramona between the Safe Routes to School Path and Broad Street. Protected bike lane separation is proposed to be installed using raised concrete curbs, with potential for landscaping or planter boxes if sufficient funding is available for ongoing maintenance, or if there is community interest in a public-private partnership to assist with planting and maintenance of landscaping (i.e. adopt-a-planter box programs). Improvements for this phase are expected to be funded through a combination of SRTS and Anholm Bikeway project funds. In conjunction with Phase 1, staff will continue development of a detailed traffic calming plan for the section of the proposed route between Lincoln Street and Ramona Drive. Opportunities for public input will be provided with development of traffic calming recommendations. Also in Phase 1, it is recommended that the City work with residents of the Anholm Neighborhood to pursue formation of a Residential Parking District if sufficient support exists within the neighborhood. A planning-level estimate of construction costs for Phase 1 improvements totals $900,000. Example photos of potential protected bike lane treatments are shown below. Phase 2 will include installation of safety lighting at the Highway 101/Chorro Street undercrossing, and implementation of essential features required to establish the Anholm Bikeway between Downtown and Ramona Drive. For this initial rollout, the section of the proposed route between Lincoln and Ramona will be retained as a shared street with installation of traffic calming measures to slow motor vehicle speeds. Installation of traffic calming features during Phase 2 may include use of lower-cost temporary materials to allow testing and refinement of features. For example, corner bulbouts may be installed using colored pavement markings and flex posts for an interim period before construction of permanent bulbouts with concrete and landscaping. As part of Phase 2, buffered bike lanes will be extended along each side of Chorro Street between Palm Street and Lincoln, with potential for future installation of physical separation. Bikeway route signage and pavement markings will be installed along the extent of the designated route. A planning-level estimate of construction costs for Phase 2 improvements totals $475,000. Protected bike lane separation is proposed to include raised concrete curbing, with potential for landscaping, planter boxes, or attractive hardscape such as stamped concrete or colored pavers. Final treatment demands on funding and maintenance resources.
Anholm Bikeway Plan V. Cost Estimates, Phasing and Performance Monitoring Strategies 37 February 2018 Example photos of potential interim and ultimate traffic calming installations are shown below. Phase 3 includes incremental installation of the remaining higher-cost project features over many years, such as installation of physical separation within Chorro buffered bike lanes (Downtown to Palm), concrete sidewalks, curb ramps, and additional street lighting. In addition, the City Council will have the discretion in future years to consider further bikeway improvements to the portion of the route between Lincoln and Ramona if the interim traffic calming measures installed during Phase 2 have not provided the intended level of low-stress bicycling environment. If the City Council desires to pursue further improvements, potential strategies may include reconsideration of protected bike lanes along this route, development of a traditional bicycle boulevard along Broad Street, or installation of permanent traffic calming features. Additional opportunities for community input will be provided if further improvements are pursued. Ultimately, the Phase 3 features cannot be funded within the budget currently available to this project. The total cost to implement all of these features is anticipated to range between $1-2 million. The City may seek additional funds for remaining project features through grant opportunities or as individual capital improvement projects based on available funding over time. While not included as a component of this project, it is important to note that the City will continue to work with Caltrans to pursue the closure of the Highway 101/Broad Street ramps. Some traffic calming measures can be implemented with temporary materials during initial project phases prior to construction using permanent materials INTERIM PERMANENT
Anholm Bikeway Plan V. Cost Estimates, Phasing and Performance Monitoring Strategies 38 February 2018 Performance Monitoring Program This plan recommends initial implementation of the Anholm Bikeway between Downtown and Ramona Drive as a pilot phase, allowing the opportunity for staff to monitor, evaluate, and refine designs as needed prior to investment in permanent features. This section outlines the recommended components of a Performance Monitoring Program to be conducted in conjunction with Phase 2, the pilot phase for the Downtown-to-Ramona portion of the bikeway route: Table 6: Performance Monitoring Program Monitoring Program Component Description & Purpose Timing/Frequency TRAFFIC VOLUME & SPEED DATA Collect roadway segment Average Daily Traffic (ADT) counts in order to identify potential shifts in traffic patterns associated with the project. Conduct vehicle speed surveys to identify potential changes in motor vehicle speeds associated with the project. Traffic counts and speed surveys will be conducted along Broad and Chorro Streets between Lincoln and Mission, as well as along nearby streets where potential shifts in traffic may occur. Before Construction After Construction o 12 & 24 months after Phase 2 Improvements BICYCLE RIDERSHIP & PEDESTRIAN ACTIVITY Collect bicycle and pedestrian counts to evaluate potential increases/shifts in bicycle ridership and pedestrian activity in conjunction with the project. Where feasible, counts will include distribution of cyclists by age (adult vs. children) and gender to study potential shifts in user demographics. Daily bicycle and pedestrian volumes to be collected for roadway segments along Anholm Bikeway route and along parallel bicycling routes. Before Construction After Construction o 12 & 24 months after Phase 2 Improvements o SAFETY Analyze reported collision data (autos, bikes, pedestrians) to identify potential safety concerns and/or trends in conjunction with the project. Collision totals and rates will be tallied for segments along the Anholm Bikeway route and compared for conditions before and after project implementation. Before Construction (summarize data for most recent 3-year average) After Construction o 12 & 24 months after Phase 2 Improvements o PARKING IMPACTS Collect on-street parking occupancy data to evaluate changes in parking demand within the vicinity of the proposed bikeway. Analysis will identify impacted street segments (where peak period parking demand exceeds available supply) and available on-street parking within reasonable walking distance of impacted segments. Peak period parking counts to be conducted along the Anholm Bikeway route and along streets within a ¼-mile walkshed of the bikeway corridor. Before Construction After Construction o 6 months after Phase 1 Improvements o 6 months after Phase 2 Improvements *Additional parking data collection may be required if other events that affect parking conditions occur concurrently with project implementation. Potential events of this type include formation of new Residential Parking Districts and/or completion of new multifamily residential or commercial development within the study area.

Anholm Bikeway Plan Appendix B: Traffic & Parking Analysis B-2 February 2018 Traffic Data Volume Data Existing (2016) roadway segment and intersection traffic data (auto, bike and pedestrian volumes) were collected for streets within the vicinity of the Anholm Bikeway. Average Daily Traffic (ADT) volumes were collected for roadway segments, while AM and PM peak hour traffic volumes were collected for intersections. All traffic data was collected during typical weekdays, avoiding school holidays, construction impacts, inclement weather or other unusual events. Existing traffic volume data is summarized in Figure B1 and Figure B2. Vehicle Speed Data City Transportation Staff collects traffic speed data regularly for the purposes of setting speed limits, investigating neighborhood traffic concerns and for studying traffic safety issues at various locations throughout the city. A typical speed survey involves the use of Lidar or Radar equipment to measure vehicle speeds along a selected corridor. Speeds are recorded for vehicles in free-flow conditions (avoiding congested locations or platoons of vehicles grouped tougher) and a sample of at least 100 vehicles is recorded in each survey. Speed data is most often used to determine the prevailing (85th percentile) speeds for a given street. Early in the project planning process, speed data was collected along streets that has potential to be considered for the Anholm Bikeway route alignment. For the purposes of this project, existing vehicle speed data was used evaluate whether conditions are appropriate for mixed-flow traffic, where bicyclists and drivers share travel lanes, and where traffic calming may be warranted to reduce vehicle speeds to a level conducive to a quality neighborhood environment. Collision History As part of the City’s Vision Zero/Traffic Safety Program, collision reports are collected from the San Luis Obispo Police Department and analyzed on an annual basis to identify collision trends throughout the City. The City’s Annual Traffic Safety Report documents citywide trends by collision type (total collisions, fatal/injury collisions, pedestrian & bicycle collisions) and identifies mitigation strategies for high-collision rate locations, with a focus on locations with high rates of collisions involving pedestrians, bicyclists and injuries. Potential mitigation recommendations may include physical improvements, as well as targeted education and enforcement strategies. As part of the analysis for the Anholm Bikeway Plan, collision data from the most recent five-year period was reviewed for intersections and streets within the project study area. This assessment included a focused investigation of locations with a documented history of pedestrian or bicycle collisions to identify potential trends that could be addressed through improvement strategies as part of this plan. A summary of pedestrian and bicycle collisions reported within the most recent five-year period (2012-2016) available is provided in Table B1.

Anholm Bikeway Plan Appendix B: Traffic & Parking Analysis B-5 February 2018 Traffic Analysis The City of San Luis Obispo evaluates vehicular traffic impacts based on roadway segment and intersection congestion/delay, as measured using auto Levels of Service (LOS)10, as well as using established maximum daily traffic volume thresholds for residential streets to assess traffic impacts to neighborhood quality of life. For the purposes of assessing potential traffic impacts related to the Anholm Bikeway project, convenience of property access and potential impacts to emergency services were also considered. Roadway Segment Levels of Service For the purposes of this plan, roadway segment levels of service were calculated for AM and PM peak hour conditions along Broad Street and Chorro Street based on Florida Department of Transportation (FDOT) 2012 Generalized Service Volume Thresholds. FDOT service volume thresholds are developed based on planning applications of the Highway Capacity Manual (HCM) and provide a convenient planning-level tool for assessing roadway segment operations. This methodology is consistent with the segment analysis included in the City’s 2014 General Plan Circulation Element EIR. The City has adopted performance target of LOS D or better for streets outside of the Downtown Core. Because the Recommended Project proposes no reductions in vehicle travel lanes, modifications to traffic circulation, or significant changes to auto capacity, roadway levels of service are anticipated to remain consistent with existing conditions. As shown in Table B2, all study segments currently operate at acceptable levels of service and are anticipated to remain at this level with the proposed project. Intersection Levels of Service Intersection levels of service were calculated for AM and PM peak hour conditions at key intersections along and within the vicinity of the Anholm Bikeway corridor. Levels of service were calculated based on 2010 HCM methodologies using Synchro 9 traffic analysis software. This methodology is consistent with the methods recommended in the City’s Traffic Impact Study Guidelines. Impacts for study intersections are evaluated based on the City’s adopted performance target of LOS D or better for streets outside 10 Level of Service (LOS) is a standard qualitative measure used to describe traffic conditions in terms of speed, travel time, delays and driver convenience. LOS is defined using letter grades “A” through “F”, with LOS A representing free-flow conditions, and LOS F representing heavy congestion with traffic demands exceeding capacity.

Anholm Bikeway Plan Appendix B: Traffic & Parking Analysis B-6 February 2018 of the downtown core. As with the roadway segment analysis, intersection levels of service with the proposed project are anticipated to remain consistent with existing conditions. As shown in Table B3, all study intersections currently operate at acceptable levels of service and are anticipated to remain at this level with the proposed project. Neighborhood Traffic Concerns The City evaluates potential neighborhood traffic impacts by comparing Average Daily Traffic (ADT) volumes and speeds along residential streets with the corresponding maximum ADT and speed targets established in the City General Plan Circulation Element.11 A proposed project would potentially trigger a neighborhood traffic impact if it would cause residential street traffic volumes or speeds to exceed these established thresholds, or if the project further increases traffic volumes on a street that already exceeds the maximum thresholds under existing conditions. As shown in Table B4, the Recommended Project does not trigger any neighborhood traffic impacts, but has potential to reduce speeds below max thresholds along Chorro and Broad Streets. 11 City General Plan Maximum ADT Targets: Local Streets (1,500 veh/day); Residential Collectors (3,000 veh/day), except Broad/Chorro north of Lincoln and Margarita (5,000 veh/day). Desired maximum speeds for residential streets are 25 mph.

Anholm Bikeway Plan Appendix B: Traffic & Parking Analysis B-7 February 2018 Parking Analysis Potential parking impacts related to the Project are evaluated by analyzing on-street parking supply and demand with and without the parking removal proposed by the project. Although the final number of on-street parking spaces impacted by the project may change slightly with final design, based on review of existing on-street parking supply and preliminary project designs, on-street parking at the following locations is proposed for removal to provide width for dedicated bike lanes and crossing improvements at intersections: Ramona Drive – 17 spaces eliminated on north side from Broad to proposed SRTS Class I Path. To better understand existing on-street parking conditions near these street segments, parking surveys were conducted in fall of 2017 for both weekday and weekend conditions during a period when local schools and Cal Poly were in session. Parking surveys included inventory of existing on-street parking supply and occupancy during various times of day along Chorro and Broad Streets, as well as along other streets within the vicinity of the proposed Anholm Bikeway. Figure B3 shows the parking study area and summarizes the existing on-street parking occupancy by time of day. As shown below, of the various periods observed, late evening on a weeknight was found to be the period where on-street parking demand is typically highest—both along the proposed route, as well as within the surrounding neighborhood. This peak period is used in the following analysis as a baseline for evaluating project-related parking impacts. 49%44%40%53%44%30%22% 22%35%25%31%35%37%29%41%31%58%50%40%64%44%60%54%48%60% 60%0%10%20%30%40%50%60%70%80%90%100%WEEKDAYEARLY AM(5‐6 AM)WEEKDAYMID DAY(12‐1 PM)WEEKDAYEVENING4‐ 5 PMWEEKDAYLATE NIGHT(12‐1 AM)SATURDAYLATE NIGHT(12‐1 AM)THURSDAYFARMERS MARKET(6‐7 PM)ON‐STREET PARKING OCCUPANCY %Chorro (Lincoln to Foothill)Chorro (Lincoln to Mission)Broad (Lincoln to Foothill)Broad (Mission to Ramona)Total Anholm NeighborhoodPEAK PARKING DEMAND ↓Figure B3: On-Street Parking Occupancy by Time of Day

Anholm Bikeway Plan Appendix B: Traffic & Parking Analysis B-9 February 2018 Existing parking conditions are mapped visually in Figure B4, with street segments color-coded based on percent occupancy and labels showing the number of available parking spaces on each block. Street segments are highlighted red where peak occupancy exceeds 85%. A parking occupancy rate of 85%-90% is typically considered the “practical capacity” of a street, meaning that there could be a few on-street parking spaces available, but drivers may have a difficult time finding them. When parking demand exceeds the practical capacity, this can lead to drivers “cruising” around the block and increases temptation to park illegally, which could impact neighborhood quality for residents. Because this segment of Ramona is near 100% occupancy currently, the displaced parking demand from Ramona is likely to extend to the adjacent streets during peak periods—likely Broad, Meinecke and further west on Ramona. As shown in Figure B4, there is generally available on-street parking within a short walk (1-2 blocks) of the section of Ramona Drive where parking removal is proposed to accommodate this displaced demand. The on-street parking removal proposed as part of this plan is not anticipated to significantly affect parking conditions or availability of parking within the neighborhood.
