CC - Item 2E - Engineering & Traffic Survey on Rosemead BlvdD4;, AD CITY COUNCIL ROSEME STAFF REPORT TO: THE HONORABLE MAYOR AND CITY COUNCIL FROM: OLIVER CHI, INTERIM CITY MANAGER DATE: JUNE 26, 2007 SUBJECT: ENGINEERING & TRAFFIC SURVEY ON (~t- C_Z_ BOULEVARD SUMMARY The California Vehicle Code (CVC) requires that an Engineering and Traffic (E&T) survey be completed every five years in order to continue using radar traffic enforcement of speed limits; this time is extended to seven years under certain circumstances. Caltrans last performed an E&T on Rosemead Boulevard in 1997, which subsequently expired on April 8, 2007. Staff was told by Caltrans that they did not have the staff nor financial resources to perform a new E&T, but that the City is welcome to complete one on their own. Staff Recommendation Staff recommends that the City Council approve the engineering proposal from Willdan to perform the E&T and appropriate the necessary funds from unappropriated reserves. ANALYSIS In the past year, nearly 35% of the speeding violations written in the City were on Rosemead Boulevard. Thus, the inability to enforce the speed limit on Rosemead Boulevard by radar would be detrimental to the City's ability to perform the necessary traffic enforcement that promotes safety for the motoring public. Willdan proposes to perform the E&T on Rosemead Boulevard for a fixed fee of $6,000. FINANCIAL REVIEW This expense of performing an E&T on Rosemead Boulevard was not anticipated and is, therefore, not in the current fiscal year's budget. Thus, the necessary funds will need to be appropriated from unappropriated general fund reserves. PUBLIC NOTICE PROCESS This item has been noticed through the regular agenda notification process.

City Engineer Attachment A: Proposal to Conduct the Engineering and Traffic Surveys on Rosemead Boulevard within Rosemead City Limits ~nnnnvcn cno rirv rni ~~~ru A/`C~If1A• • • ~WILLicDANAgenci ServingJune 4, 2007 Mr. Andy Lazzaretto City Manager City of Rosemead 8838 Valley Boulevard Rosemead, CA 91770 13191 Crossroads Parkway North, Suite 405 Industry, California 91740-3497 5621908-6200 fax 562/695-2120 ww\%.willdan.com Subject: Proposal to Conduct the Engineering and Traffic Surveys on Rosemead Boulevard within Rosemead City Limits Dear Mr. Lazzaretto: Willdan is pleased to submit this proposal to conduct Engineering and Traffic (E&T) Surveys for the City of Rosemead. We understand Rosemead Boulevard is a state highway and the survey must be prepared using the State Highways format described in the California Manual of Uniform Traffic Control Devices (California MUTCD) dated September 2006. Willdan is especially qualified to provide these services to the City of Rosemead for the following reasons: • Our professional staff serves as City Traffic Engineer for 20 Southern California cities and is well-versed on the practical and political implications of speed zoning. • Both our professional and technical staffs are thoroughly familiar with the State Vehicle Code requirements for completion of Engineering and Traffic Surveys. Our radar operators are certified and regularly trained beyond industry standards. • We have conducted Engineering and Traffic Surveys for numerous jurisdictions throughout Southern California, covering a wide range of traffic conditions on thousands of roadway miles and building a wealth of related experience. • We use our own in-house professional engineers and technicians to ensure complete quality control of our work effort and the ability to provide these services on time and within budget. June 4, 2007 Page 2 SCOPE OF WORK PROJECT APPROACH Willdan understands that the City of Rosemead is commissioning an Engineering and Traffic (E&T) Survey in order to establish and re-certify posted speed limits on three streets segments on Rosemead Boulevard. This survey will be conducted in compliance with the provisions of the California Vehicle Code (CVC), which require that such surveys be updated every 5 years to enable law enforcement agencies to perform radar enforcement. Recent changes to the CVC have allowed this time period to be extended to 7 or 10 years if specific conditions are met. The purpose of the code provisions is to guarantee that posted speed limits are kept reasonably accurate and up-to-date. Initially, Willdan will meet with the City to discuss the project and exchange relevant information. Data requested of the City will include: 1. Copy of the last Engineering and Traffic Surveys; and 2. Access to Statewide Integrated Traffic Records System (SWITRS) Reports or the City's traffic record system for the last 3 years. Willdan will provide samples of the Speed Survey Sheets, various Data Summary Sheets, Collision History Summary Sheet, and Summary of Recommendations Chart for pre-approval. A review of the current speed zone survey will be conducted with the meeting's attendees to determine if it adequately addresses the survey requirements and to identify any known changes in the existing roadway system since the last survey was prepared. The Rosemead E&T Survey will be completed in accordance with the procedures outlined in the California Manual on Uniform Traffic Control Devices (California MUTCD), dated September 2006, Chapter 2B, Section 2B and as required by CVC Section 627. Willdan proposes to perform the required services as follows: WORK PROGRAM TASK 1 - COLLECT RADAR SPEED DATA Radar speed data will be gathered for each of the three street segments included in the survey. The surveys shall not be conducted on weekends, school or civic holidays, during congested peak traffic hours, or inclement weather conditions. The data collected will consist of an optimum of 100 samples with 50 samples in each direction but not less than 50 samples or more than 2 hours of measurement for each segment. The information will be recorded on field tally sheets and will include date, time, field • 0 June 4, 2007 Page 3 conditions, weather and engineering calculations of the average speed, 85th percentile speed, 10 mile-per-hour (MPH) pace speed, and percent-in-pace. Current radar speed data will be collected by a trained, certified radar operator using a certified hand-held radar unit. The results will be analyzed to determine the average speed, critical speed, and 10 MPH pace. Task Deliverables: Speed Zone Survey Sheet TASK 2 - FIELD REVIEW AND OTHER DATA COLLECTION Using the existing survey data for reference, a field inspection and assessment of each street segment will be conducted to determine traffic and roadway conditions that are not readily apparent to motorists. Existing speed limit postings and locations will be verified. Roadway and traffic conditions, major traffic control devices, adjacent land use, and pedestrian activity will be noted. Any changes in roadway conditions since the last survey was conducted will be identified and noted on the survey data sheets. Wiltdartwill work with the City to evaluate unusual conditions on roadway segments. All field inspections will be made on weekdays when school is in session. Task Deliverables: Speed Zone Survey Sheet TASK 3 - ANALYSIS For each street segment, collision records for the most recent 3-year period using the City's SWITRS or other automated collision reporting system will be reviewed and summarized. Collision rates will be calculated and compared with the State of California average collision rates for similar roadways and street segments. The results will be summarized on survey data sheets and in tabular form. The data gathered in the previous tasks will also be summarized on the survey data sheets. Each survey data sheet will contain all of the information necessary to determine the appropriate speed limit for each street segment surveyed. After collection of all data above, the survey data sheets will be analyzed to determine the recommended speed limit based on the latest State requirements. The reasons given in the previous E&T Survey for reducing speed limits will be considered when determining the recommended speed limits. The recommended speed limits will be provided on the survey data sheets and summarized in tabular form in the Report. Task Deliverables: Speed Zone Survey Sheet June 4, 2007 Page 4 • TASK 4 - PREPARE ENGINEERING AND TRAFFIC REPORT All of the tasks in this project will be documented to form the basis of the Final E&T Report. The Report will include a written explanation of "Realistic Speed Zoning" and the requirements for conducting speed zone surveys. The Report will document the methodology and procedures used for the survey, statistical analysis factors, field data collection description, collision history, results and recommendations. It will also include excerpts from the California Vehicle Code that pertain to the establishment of speed limits. The E&T Report will include a summary of recommendations and certification pages per City standard that are often useful in presentation of information to City Council and for use in the court system. A summary of recommendations will be prepared in chart form including the street name, street segment, existing speed limit, recommended speed limit, critical (85th percentile) speed, mean speed, 10 mile per hour pace range, percent in pace, date of survey, and reason for speed limit change from the 85th percentile. Willdan carefully -constructs the recommendations summary to include clear descriptions of the app'ticaition of "conditions not readily apparent to motorists" in order to facilitate consistent interpretation of the report by the court system. Other portions of the Report will include the Table of Contents, tables, figures, and appendices such as the survey data sheets for each roadway segment and certifications for radar equipment and technicians. Four (4) copies of the Draft E&T Report will be prepared and delivered to the City for consideration by City staff. Following review and approval by City staff, four (4) bound copies of the Final E&T Report will be delivered to the City for approval by the City Council. The Final E&T Report will include a list of recommended speed limit increases and decreases. Task Deliverables: Four (4) copies of the Draft E&T Report Four (4) bound copies of the Final E&T Report TASK 5 - COLLECT TRAFFIC VOLUME DATA Twenty-four hour directional machine traffic volume counts will be conducted by a traffic counting company subconsultant for the three street segments. The counts will not be conducted on weekends, Mondays, or Fridays. Traffic volume data will be collected in hourly increments. The raw traffic volume data will be collated, alphabetized, and bound Task Deliverables: Raw Traffic Count Data Sheets for each segment bound. 0 9 June 4, 2007 Page 5 PROJECT SCHEDULE Willdan expects to be completed with all work, except submittal of the Final E&T Report and Final Traffic Count Report as defined in the Scope of Work within 6 weeks after a Notice-to-Proceed.
