FINANCIAL STATEMENT: The engineering study has been estimated to cost $23 ,000 and will be paid for with a grant from the office of Traffic Safety. DESCRIPTION On July 1, 1984 , the City of Dublin was awarded an Office of Traffic Safety Grant to conduct a comprehensive Traffic Engineering Study. This study consists of an inventory and evaluation of traffic control devices and the establishment of appropriate speed limits. A microcomputer will be purchased so the City may incorporate a traffic control inventory, speed zones, accident and cital.ion records, traffic volumes, and other traffic related efforts . The first step will be the selection of a traffic engineer . The guidelines under which the grant is regulated, require the selection of the consultant to be conducted through a "Request for Proposal" . The City has submitted the draft RFP to the State for their review. The program Coordinator has approved the format . The RFP process differs from bid procedures, in that the consultants will describe the work they will perform and the evaluation will be based on criteria contained in the RFP. This is necessary due to the specialized and technical nature of consultant services. Staff will review the proposals received and present a recommended proposal to the City Council for 'its review and approval . It is recommended that the City Council approve the draft RFP and allow Staff to circulate the RFP. ----------------------------------------------------------------=----------- COPIES TO: ITEM NO. %3•S' w DRAFT August 14, 1984 Dear Traffic Engineering Consultants : The City of Dublin has received a grant for a "Comprehensive Traffic Engineering Study" from the State of California, Office of Traffic Safety (OTS) . You are invited to submit a proposal to conduct the traffic engineering portion of this project. The following outline will provide :- information related to the City' s RFP process . EVALUATION CRITERIA When evaluating the proposals, the City of Dublin will utilize the following criteria: professional experience and excellence, demonstrated competence, experience in computerized traffic control device inventories, experience in realistic speed zoning, education and experience of key personnel, ability to meet schedules, specific professional staffing, quality of completed work, proposed schedule and fee, MBE participation, stability of firm, location and other considerations deemed relevant. SCOPE OF PROJECT The selected consultant will be expected to complete the technical aspects of the project; as outlined in the OTS application, prepare quarterly reports for review and submittal to OTS by the City, and prepare a final report meeting the technical requirements of the City of Dublin and all requirements of OTS. TECHNICAL INFORMATION The following technical information should be considered in your proposal: 1 . For the speed zone survey, the City expects to receive recommendations, which when enacted by the City Council, will allow the City to use radar enforcement on all City streets . It is expected that between 20 and 25 locations will need to be surveyed with radar during the traffic engineering study in order to meet this requirement . A list of survey locations will be proposed by the consultant and approved by the City prior to the commencement of field work. The City will make available to the consultant copies of previous years spot accident maps, SWITRS reports, and individual accident reports, if desired. The City also has a 1983 traffic flow map covering all streets which will be surveyed. The City has a recent aerial photo (one inch = 200 feet) and 200 and 400 scale base maps indicating street rights of way and property lines for use by the consultant as needed throughout the study. DRAFT Traffic Engineering Consultants Page 2 2 . On the control device inventory, the City desires to know the type, location, condition, size, mounting and other pertinent details for all traffic control signs . Similar level of detail is desired for all pavement markings, center line striping, crosswalks, and all curb markings within the City. Advance and intersection street name signs shall be included in the survey. The City also wishes to know the consultant' s recommendations for maintenance or relocation of each device (or removal if recommended) as well as the need to install any devices. Mapping will not be required. On traffic signals, the City has ten fully actuated traffic signals under its jurisdiction at the present time. Available records contain documentation* of as-builts, timing plans and related information and would require only a consolidation of all records . The City has prepared or- is in the process of preparing plan lines for the streets in the City on which the ten traffic signals are located. The consultant will be expected to take into consideration the City' s plans for upgrading signalized intersections . 3 . The City is purchasing a radar set and will purchase the computer equipment described in the OTS agreement. The consultant will be expected to provide input to the City on its selection of the computer equipment. The City will make the final selection of equipment and will make available to the consultant the purchased equipment for both the field speed surveys and for inputing the control device inventory information. The City desires to have the control device inventory data included in files so that individual devices may be addressed and updated as necessary and summary reports may be prepared on an as needed basis . Initially the City would expect to have: 1) listings of all control devices, including improvements needed, costs and priorities and; 2 ) the ability to access and update on screen the control device information at each location. Your proposal should include the information you expect to provide to the City, although it is recognized that the City and the selected consultant will arrive at a final agreed upon list of reports and procedures during the course of the study. ELEMENTS TO BE INCLUDED IN PROPOSAL Your proposal should include a breakdown of the estimate for performing the work to include the cost of direct salaries, payroll additives, other direct costs, indirect costs and profit. It should also identify the personnel who will be assigned to the project and their background. ^ Kr ♦ •r DRAFT Traffic Engineering Consultants _.......

Sincerely, Richard C. Ambrose RCA:kk City Manager SCHEDULE A PROJECT DESCRIPTION Page 1 BACKGROUND A. GENERAL CHARACTERISTICS The City of Dublin has a population of 13,500 and an area of approximately 4 square miles. Dublin was incorporated in 1982 and prior to that time was under the jurisdiction of Alameda County. Dublin , located at the junction of the I-580 and I-680 freeways, has an established residential area and growing and active commercial districts . Residential development is occurring on the edges of the City and, through General Plan activities, significant future growth through annexation is anticipated . Dublin is located in the San Ramon/Amador Valleys with a moderate climate. B. STREETS AND HIGHWAYS The Dublin street system includes some 46 maintained miles. The City has 3 principal arterials , 2 secondary arterials and several collectors. The downtown street system and all residential streets have been developed in the past three decades and reflect modern design practices . The city experiences congestion near freeway interchanges and intersections of arterials. The City anticipates substantial growth through annexation in the future. . This will result in an expanded street system with related engineering and enforcement requirements. C. OPERATING DEPARTMENTS Since incorporation , the City has begun to acquire a combination of staff and consulting services to perform its responsibilities . The City has full -time professional staff members in the City Manager ' s office and in the Planning Department. Police and maintenance services are provided by Alameda County. The City has retained the services of a consulting engineering firm to provide City engineering services. A City Engineer has been designated. A separate firm provides traffic engineering services on a contract basis to the City, on an "as needed" basis. D. EXISTING SYSTEMS The City has minimal traffic records, consisting primarily of accident and traffic volume records collected by the County of Alameda and supplemented with data collected by the consulting traffic engineer. Accident records consist of Police reports, SWITRS summaries and spot maps prepared for each year. PROBLEM STATEMENT The City of Dublin is experiencing traffic safety, traffic congestion and, to a lesser extent, traffic organizational problems. To a certain extent, all of these problems relate to the recently incorporated status of the OTS-388 ( Rev 5/82) SCHEDULE A PROJECT DESCRIPTION Page 2 City and the lack of attention to these details prior to incorporation. The City needs to have a comprehensive traffic engineering study undertaken to develop solutions for specific traffic problems and to serve as a basis for on-going and City-supplied traffic safety activities . ATTEMPTS TO SOLVE THE PROBLEMS The following is a summary of the various efforts that have been made to deal with the problem: 1. The City is preparing Plan Line Studies on 4 arterials within the City. These plan line studies include accident analysis of problem intersections and recommendations for physical improvements. Two of the plan lines have been adopted by the City Council and the other two are being reviewed by the Council . 2. The City has scheduled several major improvement projects in its Capital Improvement Projects listing . These include street and intersection widening and traffic signals. 3. The City has continued to maintain accident and volume records at about the same levels are previously done by Alameda County. 4. The City Council has adopted a number of staff recommendations dealing with signing improvements , future signals and signal systems. A significant effort to deal with accidents and congestion has been attempted. PROJECT OBJECTIVES 1. To reduce traffic accidents within the City of Dublin by approximately 20 percent . We feel this can be accomplished by adopting and implementing recommendations of a comprehensive traffic engineering study within the City. 2. Reduce congestion within the City. This will be a by-product of the short-term traffic accident reduction effort and a direct result of improved signing and signal improvements anticipated to be developed by the study.
