100 Pringle Avenue I Suite 600 I Walnut Creek, CA 94596 I (925) 930-7100 I Fax (925) 933-7090 www.fehrandpeers.com MEMORANDUM Date: December 14, 2012 To: Yvetteh Ortiz, City of El Cerrito From: Lisa Langenfeld and Sam Tabibnia Subject: Neighborhood Traffic Management Study – Colusa Avenue WC12-2889 This memorandum presents the data collection, analysis, and recommendations of a traffic calming study prepared for Colusa Avenue, in the City of El Cerrito, CA. Along Colusa Avenue, the project study area extends between Rockway Avenue in the south and Terrace Drive in the north. The study area is shown on Figure 1. The following pages present our findings for the neighborhood. COLUSA AVENUE History and Background Between Rockway Avenue and Terrace Drive, Colusa Avenue is a 2-way local street, with a posted speed limit of 25 mph. The roadway varies in width, ranging from 40-feet between Fairmount Avenue and Eureka Avenue, and 30-feet between Eureka Avenue and Terrace Drive. On-street parking is allowed on Colusa Avenue. Colusa Avenue provides direct access to El Cerrito High School, and is classified as an Emergency Response Route in the City’s Neighborhood Traffic Management Plan. It is also currently proposed as a Class III bicycle route. The minor side streets intersecting Colusa Avenue along this segment are controlled with side- street stops, including: Susan Avenue, Errol Drive, Eureka Avenue and Hotchkiss Avenue. Colusa Avenue has a side-street stop at the intersection with Terrace Drive. Two high visibility crosswalks are provided at the Eureka Avenue intersection, and one mid-block high-visibility crosswalk is provided on Colusa Avenue, between Rockway Avenue and Susan Drive. ---PAGE BREAK--- Colusa Ave Colusa Ave Bonnie Dr Bonnie Dr Balra Dr Balra Dr Clayton Ave Clayton Ave Everett St Everett St Elm St Elm St Albermarte St Albermarte St Richmond St Richmond St Norvell St Norvell St Ashbury Ave Ashbury Ave Eureka Ave Eureka Ave Eureka Ave Eureka Ave Lincoln Ave Lincoln Ave Central Ave Central Ave Seaview Dr Seaview Dr Fairmount Ave Fairmount Ave Stockton Ave Stockton Ave Terrace Dr Terrace Dr Colusa Ave Bonnie Dr Balra Dr Clayton Ave Everett St Elm St Albermarte St Richmond St Norvell St Ashbury Ave Eureka Ave Eureka Ave Lincoln Ave Central Ave Seaview Dr Fairmount Ave Stockton Ave Terrace Dr El Cerrito El Cerrito Plaza Plaza Ohlone Greeway Ohlone Greeway El Cerrito Plaza Ohlone Greeway 2 n LEGEND Colusa Avenue Traffic Calming Project Study Area LEGEND Colusa A Project S Figure 1. El Cerrito Traffic Calming Colusa Avenue Project Study Area WC12-2889_x_ColusaStudyArea ---PAGE BREAK--- Yvetteh Ortiz December 14, 2012 Page 3 of 13 Moving south to north, Colusa Avenue is relatively flat from Rockway Avenue to Susan Drive. Approaching Errol Drive, the roadway begins to slope upwards, reaching the crest at Eureka Avenue. Horizontal curves are also present on this roadway section – one near Susan Drive, and one near Errol Drive. From Eureka Avenue to the north, the slope along Colusa Avenue begins to steepen, particularly just north of Eureka Avenue, and just north of Hotchkiss Avenue. The steep roadway slope at these locations is also combined with two large horizontal curves. The northern-most intersection at Terrace Drive is at the very crest of the hill for Colusa Avenue. Sidewalks, as well as on-street parking, are provided on both sides of Colusa Avenue, although the sidewalk is often overtaken by parked vehicles. In 2010, the City of El Cerrito adopted the Neighborhood Traffic Management Plan (NTMP), which identifies a process through which a street may be evaluated for traffic control devices. If a street or segment qualifies, various measures are presented to assist with traffic control related concerns. For Colusa Avenue, the study segment meets the NTMP criteria based on the current vehicle speeds exceeding the posted speed of 25 mph by 5 mph (based on 2012 data) and the daily traffic volumes exceeding 1,000 vehicles per day. Current vehicle speeds taken on Colusa Avenue, (south of Hotchkiss) show an 85th percentile speed of 30 mph; the current ADT along this same segment of Colusa Avenue averages 2,200 vehicles per day. UNDERSTANDING OF TRAFFIC CONCERNS In response to recent concerns and a petition from the neighborhood, the City has been studying the Colusa Avenue corridor, identifying current issues and presenting potential Tier 1 and Tier 2 measures, consistent with the NTMP. Tier 1 measures include enforcement, education and outreach, as well as engineering measures limited to striping, signage, and pavement markings. Tier 2 measures are more physical elements, including speed humps, traffic circles, raised intersections, roadway closures, and enhanced crosswalk systems. Tier 1 measures are often recommended as a first step, and as more enforcement or adherence is needed, Tier 2 measures are implemented. The following concerns were raised by neighbors in a petition filed in 2011: • Speeding, especially near Eureka Avenue • Sideswipe vehicle collisions ---PAGE BREAK--- Yvetteh Ortiz December 14, 2012 Page 4 of 13 • Heavy traffic volumes during the peak commute periods • Limited sight distance at minor intersecting roadways • On-street parked vehicles blocking sidewalk and pedestrian path • Unsafe environment for multi-modal users due to the above concerns The City held a neighborhood community meeting in January 2012 to collect additional resident feedback. The following concerns were raised by residents during this meeting: • Poor Visibility (ranked highest on the northern section of Colusa Avenue between Eureka Avenue and Terrace Avenue) • Sideswipe (ranked highest on the northern section) • Speeding (entire segment of Colusa Avenue) • Sidewalk constraints (mostly recognized along northern portion) • Sight distance (northern section) • Traffic volumes (highest on southern section The main focus of this study is to present solutions that alleviate these concerns, including “calming” traffic, and improving the walkability of the corridor, providing a safer experience for pedestrians and residents. Collision History Fehr & Peers collected SWITRS (Statewide Integrated Traffic Records System) data to use in this analysis. From a review of available data between 2007 and 2010, 11 collisions were reported along Colusa Avenue, with the majority reported in 2009. The majority of the collisions reported were sideswipe collisions, followed by 2 broadside collisions, one head-on collision, and one collision with a hit object. The following collisions were reported by year. • 2 collisions in 2007 (both sideswipe) • 3 collisions in 2008 (2 sideswipe, 1 broadside) • 5 collisions in 2009 (1 head-on, and 4 sideswipe) • 2 collisions in 2010 (1 broadside, and 1 hit object) No particular trend was reported at one location – the collisions were spread out along the entire study corridor. The sideswipe collisions mostly occurred on Colusa Avenue near Susan Drive, and north of Hotchkiss Avenue, and a few on Eureka Avenue approaching Colusa Avenue ---PAGE BREAK--- Yvetteh Ortiz December 14, 2012 Page 5 of 13 Volume Data Fehr & Peers collected turning movement counts and 48-hour tube counts on Tuesday, April 24, 2012, when school was in session. Turning movement counts were conducted at the Colusa Avenue / Eureka Avenue intersection, between 6:00 AM and 8:00 PM, to capture hours with the highest number of vehicles, pedestrians and bicyclists. 48-hour tube counts were collected on Colusa Avenue, between Stockton Avenue and Terrace Drive. Recent tube counts were also conducted on Colusa Avenue, between Eureka Avenue and Terrace Drive, on Wednesday November 14, 2012. This traffic count data aided in the analysis of certain traffic control devices, including speed tables and speed lumps, and all-way stop signs. Per the criteria outlined in the NTMP, speed humps are not recommended on roadways with volumes greater than 4,000 average daily trips (ADT); traffic volumes on Colusa Avenue are less than half of this criterion, however Colusa Avenue is also an emergency response route, so speed tables or speed lumps should be considered instead of speed humps. Volumes collected in 2012 just north of Eureka Avenue identified 2,201 ADT on Colusa Avenue. Volume data collected in 2012 just south of Eureka Avenue identified 2,860 ADT on Colusa Avenue. All-Way Stop Sign Warrants The Colusa Avenue/Eureka Avenue intersection was evaluated for all-way stop control. The NTMP proposes criteria for assessing if all-way stop control should be installed at an intersection on a residential street, based on volumes (a combination of vehicle and pedestrian), collision history, and visibility. Exceptions are granted to these criteria based on the overall neighborhood circulation and special considerations. A street must meet either the volume, collision history or visibility criterion (with or without the exceptions) to be considered for an all-way stop control. These are briefly described below. Volume: The combined volume from all approaches must equal 300 units per hours for eight hours in one day, and that the minor street must equal one-third of the total entering volume, for the same eight hours of that day. Collision: The total number of reported collisions averages at least three or more per year, for at least two years. These collisions must be of the type that can be corrected by a multi-way stop sign. ---PAGE BREAK--- Yvetteh Ortiz December 14, 2012 Page 6 of 13 Visibility: If a significant visibility problem exists at an intersection for a travel distance of less than 150 feet, and cannot be corrected by other means (trimming vegetation). Neighborhood Circulation: Traffic volumes may be reduced by 60% for all the above values if the these three conditions are met: 1) neither street is an arterial street, 2) there is not a stop sign or traffic signal within 600 feet of the study intersection and 3) the stop sign installation is compatible with the overall traffic circulation within the neighborhood. Special Conditions: Traffic volumes may also be reduced to 60% of the overall values if other measures have not been effective in regulating crossing safety for pedestrians, bicyclists, or motorists within 600 feet of a school, park or playground, community facility, or on a steep grade. For the Colusa Avenue segment, the traffic volumes were reduced by 60% based on the neighborhood circulation and special conditions criteria, with the street located near a school, and the all-way stop control being consistent with the traffic flow and circulation of the neighborhood. CORRIDOR ANALYSIS Colusa Avenue, between Rockway Avenue and Susan Drive Colusa Avenue, south of Susan Drive, is flat and relatively straight, presenting a scenario for speeding vehicles. To aid in calming traffic on the beginning of the study segment, a speed lump is recommended 175 feet north of Rockway Avenue, halfway between Rockway Avenue and the mid-block crosswalk. Colusa Avenue/Susan Drive Colusa Avenue approaching Susan Drive is relatively flat in both directions, however there are horizontal curves just south and north of the intersection limiting visibility for drivers turning out of Susan Drive. To aid in increasing corner visibility, red curb is recommended on Colusa Avenue, for at least 50 feet in advance of the Susan Drive intersection, and on Susan Drive, for at least 15 feet in advance of the intersection. Alternatively, cross-hatched bulbout can also be painted at the intersection corners to reduce the corner turning radii and turning speeds. In the long-term, the painted bulbouts can be replaced with bulbouts with curbs that extend the sidewalk. ---PAGE BREAK--- Yvetteh Ortiz December 14, 2012 Page 7 of 13 Colusa Avenue, between Susan Drive and Errol Drive To address not only concerns from residents but also recent speed surveys showing vehicle speeds of 30 mph, exceeding the posted speed limit by 5 mph on this roadway segment, three equally spaced speed lumps are recommended along the roughly 1,000-foot segment of Colusa Avenue between Susan Drive and Errol Drive. Colusa Avenue/Errol Drive The approach to Errol Drive from Colusa Avenue in both directions is on a horizontal curve, presenting visibility concerns for drivers turning out of Errol Drive. To aid in increasing corner visibility, red curb is recommended on Colusa Avenue, for at least 50 feet in advance of the Errol Drive intersection, and on Errol Drive, for at least 15 feet in advance of the intersection. Alternatively, cross-hatched bulbout can also be painted at the intersection corners to reduce the corner turning radii and turning speeds. In the long-term, the painted bulbouts can be replaced with bulbouts with curbs that extend the sidewalk Colusa Avenue/Eureka Avenue At the Colusa Avenue/Eureka Avenue intersection, the all-way stop criteria were applied to evaluate the potential for stop signs on all approaches (currently only the Eureka Avenue approach is stop-controlled). The results of the volume data analysis indicate a much higher percentage of traffic on Colusa Avenue than on Eureka Avenue. With the 60% reductions in traffic permitted in the City’s NTMP, the intersection does not meet the criteria to install an all-way stop sign due to the large difference in traffic volumes on the two streets. The minor street volume is still below the 1/3 criterion in the NTMP. It is important to note that where unwarranted, multi- way stop signs may actually increase vehicle speeds, and may further decrease driver compliance. For these reasons, other treatments should be considered before all-way stop signs are installed at unwarranted locations. Analysis results are presented in Appendix B. The collision history criterion was not met at this intersection as the collisions reported did not occur at this intersection during this period of time. Of the 11 collisions reported along the corridor during the 5 year period, 4 occurred near the Colusa Avenue/Eureka Avenue intersection. Four collisions were reported in 2009; however only one collision was reported in 2008. For the criterion to be met, three collisions per year which could be corrected with multi-way stop signs would need to occur within two consecutive years. ---PAGE BREAK--- Yvetteh Ortiz December 14, 2012 Page 8 of 13 The last criterion, visibility, point to areas where visibility may obstruct the driver’s view of oncoming traffic. At the Colusa Avenue/Eureka Avenue intersection, motorists turning left from eastbound Eureka Avenue to northbound Colusa Avenue have limited visibility due to the crest vertical curve at the top of the Eureka Avenue approach to Colusa Avenue. Coupled with the northbound approach horizontal curve, this intersection presents a visibility concern that cannot be corrected through tree-trimming or other non NTMP-measures. Therefore, an all-way stop sign is recommended at the Colusa Avenue/Eureka Avenue intersection. Colusa Avenue, between Eureka Avenue and north of Hotchkiss Avenue Between Hotchkiss and Eureka Avenues, Colusa Avenue narrows to 30 feet, and presents a combination of horizontal and vertical curves that affect driver visibility in both directions. This road narrowing also leads to increases in sideswiped vehicles parked on-street. Residents raised concerns that vehicles that park on-street often block the pedestrian sidewalk to reduce their risk of sideswipe. To improve driver visibility and pedestrian walkability, red curb is recommended for the downhill portion of Colusa Avenue around the curved roadway sections (see Figure as well as centerline striping with Botts Dots. The centerline roadway striping will delineate the roadway and encourage drivers to stay within their travel lane. The centerline striping will be coupled with “SLOW” pavement markings and “curve ahead/winding road” warning signs and advisory speed limit sign for downhill traveling vehicles. The red-curb will also ensure sidewalk accessibility is provided for pedestrian use. It is estimated that this will result in loss of 9 on-street parking spaces. Speed lumps are also recommended north of the curve to calm traffic on this roadway section. These measures seek to improve the walkability, reduce collisions, and reduce vehicle speeds. Colusa Avenue, Terrace Drive Vehicles traveling north on Colusa, making a left turn onto Terrace Drive, have limited sight distance to oncoming westbound-traveling vehicles. To improve the sight distance at this intersection, 60 feet of red-curb is recommended on Terrace Drive. Vehicles traveling southbound on Colusa, approaching the Terrace Drive intersection, often reach high speeds are they begin decelerating towards and down Colusa Avenue. To slow traffic and discourage drivers from taking the corner at high speeds, striping improvements, including ---PAGE BREAK--- Yvetteh Ortiz December 14, 2012 Page 9 of 13 hatching, and either AC-curb or raised Botts Dots, are recommended to delineate the curb extension. RECOMMENDATIONS The goal of this study is to present measures that address concerns raised along Colusa Avenue. The City currently has approximately $35,000 for Tier 1 and Tier 2 improvements along Colusa Avenue. Table 1 summarizes the Tier 1 and Tier 2 measures described in the previous section that could be considered along this segment, along with their rough order of magnitude cost. Based on the City’s current budget for improvements along Colusa Avenue, and the recommended goals of this traffic calming study, the following combination of Tier 1 and Tier 2 near-term measures are suggested along Colusa Avenue. These improvements are identified on Figure 2. Recommended Near-Term Tier 1 Measures • Intersection narrowing features, including cross-hatching, at Colusa Avenue / Terrace Drive (southbound direction onto Colusa Avenue) • Red curb striping for 15 to 25 feet along Colusa Avenue in advance of Susan Drive, Errol Drive, Hotchkiss Avenue. • Red curb and centerline striping for approximately 200 feet on the south/west side of Colusa Avenue on the horizontal curves o north of Eureka Avenue o north of Hotchkiss Avenue • All-way stop sign at Colusa Avenue/Eureka Avenue Recommended Near-Term Tier 2 Measures • Speed lumps along Colusa Avenue at the following locations: o One speed lump halfway between Rockway Avenue and the midblock crosswalk o Three speed lumps between Susan Drive and Errol Drive o Two speed lumps between Eureka Avenue and Hotchkiss Avenue • Raised AC curb at the southwest corner of Colusa Avenue / Terrace Drive. ---PAGE BREAK--- Yvetteh Ortiz December 14, 2012 Page 10 of 13 TABLE 1 POTENTIAL TIER 1 AND TIER 2 TRAFFIC CALMING MEASURES – COLUSA AVENUE Tier Measure Pros Cons Approximate Cost Tier 1 Red Curb Painting Improves corner visibility On-street parking reduction $2.50 / linear foot Centerline Striping Adds roadway definition, may visually narrow the roadway Requires maintenance; compliance is voluntary $1.75 / linear foot All-Way Stop Control Will enhance visibility May increase noise in vicinity $700 per sign Intersection narrowing features, including hatching and striping May visually narrow intersection, will improve corner visibility Requires maintenance $2.00 / linear foot for striping and botts dots Tier 2 Speed Lumps High impact on reducing vehicle speeds.

May also reduce traffic volumes. Can include colored/ textured pavement High cost; may reduce emergency response times $10,000 - $15,000 each AC Curb Will add definition, may visually narrow the roadway Will require maintenance; may conflict with bicyclists; may require drainage improvements $26.00 / linear foot Enhanced Crosswalk (flashing beacons, in- roadway warning lights) Will enhance crosswalk visibility High cost; requires maintenance $20,000 to $40,000 (complete system) ADA-Compliant Curb Ramps Provides accessible path of travel High cost; may require additional improvements (drainage relocation) $3,500 - $4,000 (per each) Source: Fehr & Peers, 2012. ---PAGE BREAK--- Yvetteh Ortiz December 14, 2012 Page 11 of 13 The approximate cost for these improvements is detailed in Table 2. While the above measures are proposed to calm traffic by reducing vehicle speeds on Colusa Avenue, they may also reduce vehicle volumes as well. Based on nationally-conducted traffic calming evaluations, speed lumps are shown to reduce vehicle volumes by approximately 20%. This reduction in vehicle volumes on Colusa Avenue may cause some vehicles to divert to other parallel streets, such as Ashbury Avenue or Pomona Avenue. Alternative Near-Term Tier 1 and Tier 2 Measures As an alternative to the near-term Tier 1 and Tier 2 measures described above, the following can also be considered: • Speed tables instead of speed humps at the six locations described above • Cross-hatched bulbouts at the corner of intersections of Colusa Avenue with Susan Drive and Errol Drive Recommended Long-Term Tier 1 and Tier 2 Measures As additional funds become available, long-term solutions may include the following: • Speed feedback signs on Colusa Avenue, south of Susan Drive (approximate cost = $5,000 - $10,000) • Enhanced crosswalk and curb ramps at the mid-block crosswalk south of Susan Drive (approximate cost - $20,000 - $50,000) • Bulbouts at the corner of intersections of Colusa Avenue with Susan Drive and Errol Drive (approximate cost - $15,000 to $25,000 per corner) • Evaluation and implementation of sidewalk improvements Appendices: Appendix A: Turning Movement Counts at Colusa Avenue/Eureka Avenue Appendix B: All-way stop control analysis, Colusa Avenue/Eureka Avenue ---PAGE BREAK--- Colusa Ave Errol Dr Susan Dr Bonnie Dr Balra Dr Clayton Ave Everett St Elm St Albermarte St Richmond St Norvell St Ashbury Ave Eureka Ave Hotchkiss Ave Eureka Ave Lincoln Ave Central Ave Seaview Dr Fairmount Ave Stockton Ave Terrace Dr Colusa Ave Bonnie Dr Balra Dr Clayton Ave Everett St Elm St Albermarte St Richmond St Norvell St Ashbury Ave Eureka Ave Eureka Ave Lincoln Ave Central Ave Seaview Dr Fairmount Ave Stockton Ave Terrace Dr Errol Dr Susan Dr Hotchkiss Ave El Cerrito Plaza Ohlone Greeway El Cerrito Plaza Ohlone Greeway El Cerrito High School El Cerrito High School 12’ SOUTHBOUND 10’ NORTHBOUND 8’ PARKING • Prohibit on-street parking around curve • Add “SLOW” pavement markings 2 n LEGEND Colusa Avenue Traffic Calming Project Study Area Red Curb Painting Intersection Striping Speed Lump All-Way-Stop Signs Centerline Striping Botts Dots/AC Curb Figure 2.
