5 ITEM 2. TC LOCATION: REQUEST: INITIATED BY: Harbinson Avenue Harbinson Avenue Traffic Calming Staff ISSUES: Annual Report on Harbinson Avenue Traffic Calming RECOMMENDED ACTION: 1. Request the Police Department to conduct regular enforcement activity on Harbinson Avenue and keep records of such activity. 2. Install proposed striping and signage enhancements at the medians and traffic circles. 3. Install proposed parking lane striping and pedestrian lane striping. 4. Remove on street parking around the traffic circles. 5. Investigate the feasibility of installing additional street lighting. 6. Report back six months after implementation of the above recommendations. BACKGROUND INFORMATION: A petition for traffic calming on Harbinson Avenue was first submitted on September 26, At that time the City of La Mesa did not have a comprehensive traffic calming program to evaluate, rank and prioritize streets for implementation. The City Council adopted the Neighborhood Traffic Management Program in 2004 and during that initial prioritization Harbinson was ranked number 5 out of 42 streets on the list. One of the objectives of the Program was to implement at least some, minimal measures for each street while the street waited its turn to reach the top of the prioritized list. The initial traffic calming measures typically consisted of signage and striping installation and was described as Phase 1 traffic calming. Phase 1 traffic calming was implemented on Harbinson Avenue in November In 2010, Harbinson had reached the top of the traffic calming list of ranked streets allowing it to proceed to Phase 2 of the Program. In February, 2011, a meeting was held with about 30 Harbinson Avenue residents to review traffic calming options. At the meeting, maps of the street were distributed, and the residents wrote on the maps what their traffic concerns were. Fourteen residents volunteered to continue working with City staff to refine concepts and work with the neighborhood. Staff met with the core group of residents multiple times and developed two traffic calming alternatives. Since Harbinson Avenue was a local collector street use of the street by emergency responders was part of the evaluation of which traffic calming tools were most appropriate. Emergency responders typically prefer less intrusive traffic calming measures for less impeded emergency response. Alternative 1 consisted of installing six intersection medians, two traffic circles and one pork chop island. Alternative 2 was installing six speed cushions. A third alternative was to not do anything.

6 Medians are raised islands in the center of the street designed to narrow travel lanes and lower vehicle speeds. The medians are located near intersections of cross streets. Traffic circles are raised circular islands installed in an existing intersection. Traffic circles provide speed control by requiring drivers to slow down to maneuver around them. The circles may also be landscaped to increase aesthetics. A pork chop island is a triangular shaped island used in wide intersections to separate right-turning vehicles from through lanes and to provide a refuge area for pedestrians. In September 2011 three hundred eighty two (382) ballots were mailed to residents asking them to vote for their preferred alternative. The noticing area was 300 feet wide on both sides of Harbinson Avenue. An exhibit was provided with the ballot to show residents where the proposed circles and medians would be located. One hundred sixty (160) ballots were returned, which is a 42% return rate, and is greater than the 40% return rate required by the Program. Of the one hundred sixty (160) ballots, one hundred five (105) voted for Alternative 1, which is the traffic circle/median alternative. This equaled 66% of the total votes in favor of Alternative 1. The program requires 67% of the votes in order to proceed with the traffic calming program. None of the other alternatives garnered enough votes to meet the 67% requirement. This item was discussed at the December 2011 Traffic Commission meeting. At this meeting, staff presented a report and the Traffic Commission heard testimony from residents. Several residents had concerns regarding the plan, so the commission chose not to approve the project at that time and asked staff to meet with the concerned residents to see if their issues could be mitigated. At the December meeting, four residents spoke in favor of Alternative 1 and four residents spoke against the proposed plan. All speakers agreed that there was a traffic problem and that something should be done. The four residents speaking against the proposed plan had the following concerns: 1) preferred use of stop signs, 2) wanted sidewalks instead, 3) loss of on-street parking, 4) increased traffic flow due to the traffic signal at University Avenue, and 5) belief that the islands will be hazardous. Since the plan was conceptual at that point, concerns such as loss of on-street parking could be addressed during the engineering design phase. Harbinson Avenue is forty feet wide along most of its length, therefore, a four foot wide median could be installed and still retain on-street parking. Likewise, at the intersections with the proposed traffic circles, the design of the circles could take into account a desire to minimize the impact to on-street parking. The dimensions of each circle/median were determined during the design phase to provide for safe passage by emergency vehicles, in addition to passenger vehicles and pedestrians. Following the December meeting, staff made an effort to meet with those residents expressing concerns with the concept plan. Most of the residents that expressed concerns with the project at the December meeting were now in support of the project. On March 7, 2012 the Traffic Commission approved recommending to City Council approval of Alternative 1 traffic calming measures. On March 27, 2012, the City Council approved going forward with the Alternative 1 traffic calming measures. The design was performed by Kimley-Horn & Associates and on July 23, 2013, City Council approved awarding the construction contract to Blue Pacific Engineering and Construction for $89,740. Construction of the traffic calming measures on Harbinson Avenue was completed in December The City filled the traffic circles with top soil and planted them. A group of residents volunteered to maintain the landscaping.

7 The project consisted of installing six intersection medians, two traffic circles and one pork chop island. The Neighborhood Traffic Management Program requires that traffic calming projects be monitored for effectiveness during the first year following completion of the installation, and that annual reports be provided to the Traffic Commission at the end of each of the first two years of the completed traffic calming project. This is the first year annual report. Prior to the preparation of this report a neighborhood meeting was held on Saturday, February 21, 2015 at 10 a.m. in the Police Department Community room. Meeting notices were mailed to 382 properties within the project area of influence. Thirty seven residents attended the meeting. Twenty of the attending residents live on Harbinson Avenue and the remaining seventeen live on the adjoining streets. Notices were also mailed to the project area of influence for the Traffic Commission meeting. DISCUSSION: This report will present a discussion on speed and collision data, and provide recommendations for the traffic calming features on Harbinson Avenue. Street light locations were reviewed on Harbinson Avenue to ensure that lighting at the traffic calming features was adequate. All except one of the traffic calming features have a street light near-by. Staff could investigate whether or not a light can be installed on the power pole on the southwest corner of Harbinson Avenue and Camellia Drive to improve lighting at the intersection. Table 1 shows the speed data that s been obtained before and after installation of traffic calming measures. The data taken in May and August of 2014 was after installation of the medians and traffic circles.

More importantly, there is also, a reduction in the maximum recorded speed from 61.2 mph before to 49.5 mph after installation. Data on the northern end does not have a similar reduction in the 85 th percentile speed

8 but there was a reduction in the maximum speed again from 69.9 mph to 59.4 mph. Although the goal of any traffic calming is to safely reduce all speeds, it is most important to reduce the maximum speeds as this is where injury collisions are most likely. The Police Department disployed the radar speed trailer in August and October. Traffic officers have been working Harbinson Avenue on various occasions. Although the traffic calming measure installations were completed in December 2013, no accidents were reported on Harbinson Avenue until August Since August there have been four reported collisions on Harbinson Avenue. Two accidents were caused by drivers driving under the influence of alcohol, one recent collision occurred during the day and was caused by distracted driving, and the most recent collision occurred north of Annapolis by a speeder. Staff requested Kimley-Horn and Associates, the City s on call traffic engineering firm to review the speed data, collision reports, and current conditions in order to provide some analysis and recommendations with respect to Harbinson. Kimley-Horn s report is attached. After reviewing the collision reports, Kimley-Horn came to conclusion that the addition of the traffic calming features did attribute to the cause of the collisions. Kimley-Horn also prepared some recommendations for signage and striping enhancements to the traffic calming features. Figure 1 shows yellow centerline striping around the median islands to help drivers better indentify the medians. Figures 2 and 3 show enhancements at the two traffic circles. Splitter island striping along the approaching centerlines will help guide the driver around the circle. Edgeline striping will better show the driver where the edge of the travel lane is. Based on feedback from the residents, lack of continuous sidewalks and pedestrian safety was a concern. Figure 4 shows some striping which could allow pedestrians to walk along the side of the roadway by defining a pedestrian lane. The pedestrian striping could be implemented along a portion of the street on a trial basis. NEIGHBORHOOD MEETING: At the neighborhood meeting on February 22 nd a brief presentation was given by staff discussing the steps involved with the project. Exhibits were presented which showed historical traffic speeds and the location where the data was observed. It was noted that the maximum speeds have been reduced substantially. Staff presented three exhibits with signage and striping enhancements. After the presentation, everyone that submitted a speaker card was able to address the group. Their comments were documented and are attached as Attachment A. Staff had prepared voting boards with options for the residents to vote on and encouraged people to write in any other suggestions they had. Harbinson Avenue residents were provide three red dots and other residents had three blue dots. The dots had numbers 1 through 3 written on them and the residents were asked to place the dot with the number one on it on their preferred option and then the other two dots accordingly. The results of the voting are presented in Attachment B. The highest priority one votes went to removing the traffic circle at Annapolis. There have been two recent collisions just south of the traffic circle. A resident north of the circle at Watson Way reported that their vehicle has been hit three times this year.

9 Other than the residents saying that they feel the median islands are ineffective, there wasn t support for their removal. Speed humps received five priority one votes from the Harbinson Avenue residents. Because Harbinson is a primary emergency response route the installation of speed humps is not supported by the police or fire departments. La Mesa has installed speed cushions which are speed humps with slots in them for emergency vehicles to pass through on two streets, but there is consistent reported violation of the center line by vehicles attempting to pass through the emergency vehicle slots. RECOMMENDATION: Staff has the following recommendations for the traffic commission. 1. Request the Police Department to conduct regular enforcement activity on Harbinson Avenue and keep records of such activity Enforcement is an important part of any successful traffic calming program. The police department responds to citizen requests for enforcement and works with the public works department in the implementation of the Neighborhood Traffic Management Program. Police motor units and the radar speed trailer have been deployed on multiple occasions on Harbinson and the department has committed to continue to allocate resources to enforcement on this street in an attempt to provide a presence that reduces vehicle speeds and increases safety. 2. Install proposed striping and signage enhancements at the medians and traffic circles The striping and signage enhancements proposed by Kimley-Horn (Figures 1, 2, and 3 of the attached report) will provide additional, clearer information to drivers using Harbinson Avenue. Traffic engineering and traffic calming can be an iterative process. The proposed changes attempt to address some of the resident s concerns with the traffic circles by providing better information for drivers. 3. Install proposed parking lane striping and pedestrian lane striping The proposed parking and striping will create a narrower travel lane and a defined pedestrian lane. The forty-foot wide width of Harbinson (in many places) gives drivers the comfort to drive quickly. One of the repeated complaints by users of Harbinson is that there are no sidewalks on it. Sidewalks are identified for Harbinson in the Sidewalk Master Plan but there is no identified timetable for their construction. Construction of sidewalks is typically done by private development. Since the street is wide enough a lane could be painted to create a sidewalk within the street. A second lane could be painted to define a parking lane. This parking lane would have the added effect of narrowing the travel lane on Harbinson and could result in some vehicle speed reductions. The proposed parking lane and pedestrian lane striping could be installed on a portion of the street and evaluated for further implementation. 4. Remove on street parking around the traffic circles One of the challenges of installing some traffic calming tools is loss of on street parking. Loss of on street parking is typically met with resistance from residents. Removal of parking around the circles could reduce the potential for collisions with parked cars and permit the

10 installation of a curb or other feature in an attempt to deflect any vehicle leaving the travel lane. 5. Investigate the feasibility of installing additional street lighting Staff plans to investigate existing street lighting on Harbinson and if necessary and possible have additional lighting installed to increase safety. 6. Report back six months after implementation of the above recommendations Staff is prepared to report back six months after the installation of any of the proposed modifications if they are approved. Should the Traffic Commission approve any of the above recommendations staff will then prepare a staff report for City Council consideration and approval. Attachment: A. Speaker comments B.

11 Harbinson Avenue Traffic Calming Meeting Notes 02/21/15 Harbinson Ave. Residents/Non-Harbinson Ave. Residents Who Spoke During the Meeting: Tony Ortega Dana Dr. - Commented that we have to look at the overall concept, pedestrian and traffic. People are upset that change is not happening right now. Maybe we need to look at a physical way of helping the problem, trees, lighting, striping. Nicole George Harbinson Ave. - She went around the neighborhood to get votes on the traffic calming. She wanted speed bumps. Her car has been hit. She mentioned that people need to be more positive and try to figure out what we want. She is scared to walk her daughter on Harbinson Ave. Larry George Harbinson Ave. - Proposed putting speed bumps between Annapolis Ave. and Purdue Ave. as people are speeding. Rush hour in the morning between 6am-8am and in the afternoon between 3pm-5pm. Ron Whitaker Harbinson Ave. - Has lived on Harbinson Ave. about a year and a half. Directed most of his questions and comments to Officer Bill Wilson. He asked how many speeding tickets have been given on Harbinson Ave.? How many warnings have been given on Harbinson Ave.? Officer Wilson said that he does not give warnings and the exact number of speeding tickets was not mentioned but the number of speeding tickets was much lower than expected. Mr. Whitaker mentioned that people often pass him while he drives the speed limit on Harbinson Ave. Daniel Castillo Harbinson Ave. - Has lived on Harbinson Ave. a year. An accident occurred where the car plowed thru Mr. Castillo s front yard. He has two children, one special needs and their bedrooms face Harbinson Ave. After the accident occurred Mr. Castillo took out the hedges in the front yard and built a concrete wall to protect his children s bedroom. He proposed removing the round-about, putting a stop sign at Annapolis and Harbinson and speed bumps. He commented that something physical was needed to stop people and the sling shot effect happening on Harbinson Ave. Alexandra Ramirez Harbinson Ave. - Curb was painted red outside of home, inconvenient but not a problem. Her jeep was hit, along with her parents suburban and when police came out a report was not taken because the person who hit their cars was not seeking medical aid. Wants to find a solution, possibly lowering the speed limit on Harbinson Ave. James Cabrera Harbinson Ave. - Renting home since August Has 2 young children. Would like the round-about removed and speed bumps put in on Harbinson Ave. Joe Anaya Harbinson Ave. - Lived on Harbinson Ave. for 35 years. Has had 7 vehicles hit.

Mr. Smith suggested putting in sensor botts dots on Harbinson Ave. Mr. Smith said that people needed to be more proactive to find a better solution.

12 Donald Enochson - Lived in his home for 32 years. Says the City is not addressing the real problem. Harbinson Ave. needs to be a hassle or nuisance for people to drive down. 25 years ago the City discussed closing one end of Harbinson Ave., however too many people voted against it. Mike Ewing Harbinson Ave. - Proposed removing the two round-abouts and diverting more money back to the police department to write speeding tickets.

14 MEMORANDUM To: From: Ms. Kathy Feilen, P.E. Jon Collins, PE Kimley-Horn and Associates, Inc. Date: January 19, 2015 Subject: Harbinson Avenue Traffic Calming Solutions Included in this memo are some recommended enhancements for the traffic calming measures for Harbinson Avenue. Project Background As part of the Neighborhood Traffic Management Program, traffic calming measures, including intersection medians and traffic circles were installed on Harbinson Avenue. Construction of these measures was completed in December As part of the Neighborhood Traffic Management Program, the measures are required to be monitored for effectiveness during the first year following completion of the installation. Speed data along Harbinson Avenue was obtained before and after the installation of the traffic calming measures. According to the speed survey conducted by Kimley-Horn in June of 2014, the 10 mph pace was mph; more importantly 77 percent of vehicles were traveling at this speed range. As presented at the meeting, the highest speed and 10 mph pace decreased compared to preconstruction speed data. It was also presented that there had been four reported collisions on Harbinson Avenue since construction has been completed. Two accidents were caused by drivers under the influence of alcohol and one was caused by distracted driving. Based on my review of the accident data, I do not believe that the accidents were attributed to the addition of the traffic calming features. The addition of more traffic calming features along the roadway to enhance what has currently been installed will make drivers more aware of the different characteristics of Harbinson Avenue and result in lower speeds as drivers will be more attentive to the physical changes to the roadway. Kimley-Horn also presented additional traffic calming enhancements at that meeting. This memo summarizes my recommendations and is intended to also be included in the Harbinson Avenue Traffic Calming Annual Report. Striping Solutions Design and construction of the traffic calming measures along Harbinson Avenue has been an iterative process. As, such some (if not all) of the proposed enhancements can be easily implemented and evaluated. Presented in this section are enhancements to the existing measures that have already been installed. kimley-horn.com 401 B Street, Suite 600, San Diego, CA

15 Page 2 MEDIAN IMPROVEMENTS Median improvements consist of curb striping to narrow the travel lanes at each new median. Figure 1 shows the proposed improvements for the median locations. At the intersections of Harbinson Avenue at Cornell Avenue, Camella Drive, and Amherst Street, it is recommended to add edge line yellow striping around each existing median (as shown in Figure 1). During the original design of the traffic calming measures, the loss of parking at the medians was a concern. To retain existing parking, striped parking lanes and edge line striping can be added at the medians to narrow the travel lanes on Harbinson Avenue. The width of the edge line yellow striping can be altered accordingly to provide for the desired travel lane width. TRAFFIC CIRCLE TAPER IMPROVEMENTS Traffic circle improvements consist of pavement striping changes and additional signage. Figures 2a and 2b show the existing and proposed improvements for the intersection of Harbinson Avenue and Annapolis Avenue. Figures 3a and 3b show the existing and proposed improvements for the intersection of Harbinson Avenue and Watson Way. At the intersections of Harbinson Avenue at Annapolis Avenue and Watson Way, it is recommended to add striping to the traffic circle to facilitate slower speeds by enforcing greater deflection at the intersection approaches (as shown in Figures 2b and 3b). As part of the improvements it is recommended to install advanced signage. The advance signage could have an advisory speed as well as the symbols for the geometric changes associated with the traffic circle. PEDESTRIAN LANE STRIPING One of the most common concerns from residents was the lack of sidewalk requiring residents to walk in the roadway next to the moving traffic. I am proposing to restripe a portion of Harbinson Avenue to add a pedestrian walkway. Pedestrian improvements consist of pavement striping changes on Harbinson Avenue from Annapolis Avenue to Stanford Avenue. Figure 4 shows the proposed improvements for this roadway segment. Harbinson Avenue does not currently accommodate for pedestrians and they must walk in the travel way. With vehicles going speeds of 30 mph and greater, pedestrians feel unsafe when walking along the roadway. The striping improvements shown in Figure 4 not only provide pedestrians with their own space but also provide a buffer between moving vehicular traffic and the pedestrian area. Conclusions The improvements included in this are intended to be included in the Harbinson Avenue Traffic Calming Annual Report. These improvements were designed in response to staff and residents concerns. They represent solutions that have the ability to reduce speeds and increase pedestrian separation from traffic along Harbinson Avenue. kimley-horn.com 401 B Street, Suite 600, San Diego, CA
