Background {city ofCarlsbad Memo ID# 2019109 Since 2017, an ongoing dialogue has taken place regarding traffic calming improvements that were implemented on Harbor Drive. This dialogue has consisted of City Council inquiries, emails, telephone conversations and in-person meetings with residents of Harbor Drive and various city staff members, including interactions with the city manager, chief operations officer, deputy city manager of the Public Works Branch, city traffic engineer, transportation director and other personnel in the Transportation and Police Departments. Most recently, project updates were mailed to neighborhood residents on April 16 and July 24, 2019. Another project update will be mailed to residents on Sept. 26, 2019. Discussion Harbor Drive was evaluated in accordance with the Carlsbad Residential Traffic Management Program (CRTMP). On Sept. 21, 2017, staff conducted a neighborhood meeting at the Senior Center to develop a traffic calming plan for Harbor Drive. A plan comprised of two speed cushions was selected as the preferred concept by a majority of meeting attendees. On Dec. 4, 2017, staff presented results of the traffic calming process on Harbor Drive to the Traffic Safety Commission (Attachment A). After hearing staff's presentation and public comments, the Traffic Safety Commission voted unanimously in support of the Harbor Drive traffic calming plan as presented. Prior to completing the final construction plans, prototype ·speed cushions were constructed and then tested and approved by emergency services staff. On July 10, 2018, the City Council approved the construction plans for the proposed speed cushions (Attachment B). A construction contract was executed on Aug. 14, 2018, and the speed cushions were put into service in September 2018. Since then, staff has been monitoring the effectiveness of the speed cushions. Speed measurements were taken on three separate dates, including Nov. 6, 2018, and the busier Fourth of July and Labor Day holiday weekends, to measure and compare critical speeds.

SA LOCATION: INITIATED BY: Michael Shannon, 4050 Harbor Drive, Carlsbad, CA 92008 Recommend City Council approval of the Harbor Drive Traffic Management Plan REQUESTED ACTION: BACKGROUND: DATA: In response to resident concerns about vehicle speeding on Harbor Drive, staff has been working in collaboration with the residents to develop a traffic m,inagement plan that would address their concerns. On April 10, 2017, the Traffic Safety Commission supported staffs recommendation to develop a traffic management plan to reduce vehicle speeds. Staff invited residents to a neighborhood meeting on September 21, 2017 to discuss traffic management strategies and to develop a traffic management plan for Harbor Drive. At the meeting, a plan comprised of two speed cushions on Harbor Drive was proposed to the general approval of the meeting attendees. After the neighborhood meeting, surveys were sent to the residents on Harbor Drive to determine if a majority of the residents supported the traffic management plan. Based on the results of the resident survey, staff is recommending that the Harbor Drive traffic management plan be approved by City Council. · Harbor Drive is a cul-de-sac street with access from Chinquapin Avenue on its northerly terminus. A pedestrian path to Agua Hedionda Lagoon is located at the south end. Traffic data collected on September 2016 estimates that the average daily traffic using Harbor Drive ranges from 191 to 298 vehicles. This traffic consists of visitors to Agua Hedionda Lagoon, residents who live in the 18 homes fronting Harbor Drive, as well as residents, visitors and deliveries to the apartment complex which fronts the lagoon. The street is 36 feet wide with curb and gutter and no side sidewalks on both sides. On- street parking is permitted on both sides of the street. Harbor Drive is approximately 645 feet from Chinquapin Avenue to the center of the cul-de-sac end. Speed measurements were performed on Harbor Drive on several different occasions. Portable speed feedback signs were deployed in early July 2017 and indiqited a critical (or 85th percentile) speed of 17 mph in the northbound direction and 21 mph in the southbound direction. Speed data was also collected in September using hose counting equipment, indicating critical speeds of 23 mph in the northbound direction and 24 mph in the southbound direction. The posted speed limit on Harbor Drive is 25 mph. A query of our collision data base indicates that there have been no reported collisions on Harbor Drive from 1/1/2008 to 8/4/2017. Please note that only reported collisions Page 1 COMMISSION MEETING OF: (continued) CITY OFCARLSBAO TRAFFIC SAFETY COMMISSION STAFF REPORT December 4, 2017 ITEM NO. 6A are contained in the database and does not include minor' collisions and incidents that are not reported to the police department. The staff report presented at the April 10 TSC · meeting recommended that a neighborhood meeting be held and the Traffic Safety Commission voted to support a project for traffic management features to be implemented on Harbor Drive. A neighborhood meeting was held at the Carlsbad Senior Center on September 21, 2017. Invitations to all of the eighteen single family home residents and owners were mailed and eighteen residents attended the meeting. Staff heard resident concerns and presented the strategies and tools that the Carlsbad Residential Traffic Management Program utilizes to address speeding on residential streets. By the conclusion of the meeting, a draft concept plan comprised of two speed cushions was developed and supported by the majority of the meeting attendees. Per the requirements found in the Carlsbad Residential Traffic Management Program, implementation of the proposed plan requires that a majority of the residents on the street express positive support the plan as determined by responses to a mailed resident survey. The survey is considered valid if 50% or more of the residents and nonresident owners return the completed survey. Positive support for the plan is indicated by 67% or more of the returned surveys in support of the proposed plan. Nineteen surveys were mailed out to residents and non-resident owners on Harbor Drive. Sixteen surveys were returned, which represents an 84% return rate. Of those sixteen returned surveys, twelve (75%) were in support of the proposed plan. Both Carlsbad Residential Traffic Management Program requirements related to the survey were met. RECOMMENDATION: Based on the findings contained in this report, and the requirements of the Carlsbad Residential Traffic Management Program, staff recommends City Council approval of the Harbor Drive traffic management plan.

Attachment B CA Review H> Adopt a Resolution approving plans for the Daisy Avenue and Harbor Drive Traffic Calming Project, Project No. 6070, per the Carlsbad Residential Traffic Management Program. Executive Summary Carlsbad uses the Residential Traffic Management Program (CRTMP) to address speeding on residential streets. City Council adopted the CRTMP in 2001 by adopting Resolution No. 2001- 139, and amended it in 2011 by adopting Resolution No. 2011-115. Daisy Avenue and Harbor Drive have completed the collaboration process outlined in the CRTMP and have met the criteria for neighborhood support for their respective traffic calming plans. In accordance with the CRTM P project approval process, staff is requesting that the City Council approve the Daisy Avenue and Harbor Drive Traffic Calming Project, Project No. 6070 (Project). Page nine of the CRTMP states that, "a duly noticed public meeting will be held by the City Council to receive the recommendations ofthe Traffic Safety Commission for Phase II implementation." Discussion The CRTMP was designed to address vehicle speeding on residential streets, and outlines a collaborative process between city staff and neighborhood residents to develop solutions that address resident concerns. The collaboration includes neighborhood meetings to hear resident concerns and to help formulate specific traffic calming plans tailored for each neighborhood. It also includes a mail survey to measure neighborhood support. Per the requirements found in the CRTMP, implementation of a proposed traffic calming plan requires that a majority ofthe neighborhood express positive support. The survey is considered valid if 50 percent or more of the mailed surveys are returned. Positive support is indicated by 67 percent or more of the returned surveys in favor of the proposed plan. Daisy Avenue Public Input Process On April 20, 2017, staff conducted a neighborhood meeting at Alga Norte Park to hear resident concerns, discuss traffic calming strategies and to develop a traffic calming plan for Daisy Avenue. A plan comprised of two speed cushions was selected as the preferred concept by a majority of meeting attendees. After the neighborhood meeting, and in accordance with the CRTMP, surveys were sent by mail to residents and property owners on Daisy Avenue to gauge neighborhood s1,1pport for the preferred concept plan. A total of 90 surveys (75 residents and July 10, 2018 Item #6 Page 1 of 6 16 non-resident owners) were mailed out for the Daisy Avenue t raffic calming plan. 62 signed surveys were returned to staff, which represents a 69 percent return rate. Of the 62 returned surveys, 44 were in support of the proposed plan, which represents a support rate of 71 percent. Based on these results the survey is considered valid and the proposed plan has sufficient support from the community. On Feb. 5, 2018, staff presented results of the traffic calming process on Daisy Avenue to t he Traffic Safety Commission. After hearing staff's presentation and public comments, the Traffic Safety Commission voted unanimously in support of the Daisy Avenue traffic calming plan as presented. Harbor Drive Public Input Process On Sept. 21, 2017, staff conducted a neighborhood meeting at the Senior Center to develop a traffic calming plan for Harbor Drive.

A total of 19 surveys {18 residents and 1 non-resident owner) were mailed out for the Harbor Drive traffic calming plan. 16 signed surveys were returned to staff, which represents an 84 percent return rate. Of the 16 returned surveys, 12 were in support of the proposed plan, which represents a support rate of 75 percent. Based on these results the survey is considered valid and the proposed plan has sufficient support from the community. On Dec. 4, 2017, staff presented results of the traffic calming process on Harbor Drive to the Traffic Safety Commission. After hearing staff's presentation and public comments, the Traffic Safety Commission voted unanimously in support of the Harbor Drive traffic calming plan as presented. Based on the results of the support surveys for the traffic calming plans on Daisy Avenue and Harbor Drive and the requirements found in the CRTMP, staff recommends City Council approval of the Project. Prior to completing the preparation of the construction plans, prototype speed cushions were constructed and then tested and approved by emergency services staff. The Project construction plans for Daisy Avenue and Harbor Drive have been completed and are on file at the Public Works Department. The two projects will be bid together. The estimated cost to construct these improvements is less than $175,000 and therefore the construction contract will be executed by the City Manager or designee.
