Principal Planner City of San Rafael 1400 Fifth Avenue P.O. Box 151560 San Rafael, CA 94915-1560 SEP 9 Regarding: St. Vincent's/Silvera Ranch Study area (PHASE I) Dear Jean: Wilbur Smith Associates (WSA) is pleased to have this opportunity to work with you on this project. It is our understanding that this project would be divided into two phases and that you would like WSA to propose separately on each. This letter contains a brief outline of the overall project and the scope of work, fee and schedule proposal for the first of the two phases. PHASE I - The first project would consist of updating the existing City traffic model which was prepared by WSA in 1986 and has been updated since. The study area zones and intersections are shown in Exhibit 1 attached to this proposal. This Phase would consist of updating existing traffic volume files, updating network geometry files where roadway configurations have changed, and subtracting development which has occurred since the preparation of the original model from the traffic model (since these developments will be included in the existing conditions counts). Also, if changes have been made to the General Plan since the preparation of the original traffic model, WSA would want to update its land use assumptions. No trip rates will be changed in this phase of the project as the rates from the General Plan Circulation Element will be used. The purpose of this task would be to get an accurate reading of the existing traffic conditions in San Rafael and to forecast future traffic conditions. The results of this task would be presented in report format to the City of San Rafael. PHASE II - The second phase of the project, which will be further discussed in separate letter, will be to evaluate the growth potential in the St. Vincent's/Silvera Ranch study area. In this phase of the project, three land use assumptions will be added to future build -out traffic estimates. The results of Phase I of the project will be used for the build -out traffic conditions. The land use assumptions will vary in development type and density. For each of the three land use assumptions, three different future roadway scenarios will be used. The purpose of this task will be to 1) determine the maximum development which could occur in the area of the project under various circulation networks, and then to 2) analyze impacts of development alternatives and to determine which of the proposed future roadway networks would best accommodate the future development scenarios.

DC EMPLOYEE -OWNED COMPANY Jean Freitas September 4, 1991 Page 2 Also as part of this phase, WSA will develop rail alignment alternatives for the NWPRR and will discuss transit and parking in the study area. The result of this phase of the study will be presented as a transportation impact study. Scone of Work This letter proposal focusses on Phase I of this project. As stated, Phase II will be addressed in a separate letter proposal. WSA proposes a five task scope of work for PHASE I of this project. They consist of. (1) Updating existing traffic volumes; (2) Updating network files; (3) Updating General Plan build -out files; (4) Running the traffic model; and (5) Presenting findings. Each of these tasks is discussed in greater detail below. Task 1 - Undatine Existing Traffic Volumes This task will consist primarily of gathering recent turning movement count data at the study intersections. Nader Mansourian, of the City of San Rafael, supplied WSA with a list of recent traffic counts which will be used where possible. In many cases, however, new traffic counts will have to be conducted. No traffic counts more than two years old will be used. Based on the study intersections which were included in the past traffic model and on a list of counts provided by the City, new counts will need to be conducted at 27 locations during the PM peak period. Additional intersections could be added to the traffic model at additional cost. The cost would be approximately $800 per additional intersection. This estimate includes the cost of counting the intersection as well as adding it to the model and carrying the analysis through the remainder of the study. Task 2 - Updating Network Files This task will consist of updating the roadway network geometry files where roadway and intersection improvements have been made. The model was last updated in February of 1988. Also as part of this task, WSA will review and update (where necessary) the traffic distribution assumptions made in the last traffic model. Task 3 - Updating General Plan Build -Out Files The traffic model's future traffic forecasts are based on land use assumptions for future development. The types and quantities of future development are estimated based on the City of San Rafael's General Plan. In order to depict an accurate picture of the General Plan build -out traffic conditions, WSA will update its General Plan assumptions. Important issues in this update will be any changes to the General Plan since the update to the traffic model, so that land use assumptions can be changed accordingly, and development which has occurred since the update, so that development which was slated to occur and which now has occurred can be subtracted from the future development scenario. In order to complete this task, the City of San Rafael will need to provide WSA with a copy of the City's most recent General Plan, copies of amendments to the General Plans, and a list of projects which have occurred since the update to the traffic model. Jean Freitas September 4, 1991 Page 3 Task 4 - Runnine the Traffic Model In this task, the traffic model files will be updated and the traffic model will be run for existing PM peak hour conditions and General Plan build -out conditions. Task 5 - Presentine Findings The results of the traffic model runs will be presented in a report to the City. The report will document important assumptions and methodology. Also included in the report will be copies and explanations of all of the model's inputs and outputs. This will allow other professionals to understand what land uses were assumed, what trip generation assumptions were used, how vehicles were distributed between zones, what road configuration assumptions were made, and what the resulting levels of service were. Included in the explanation of the generation file will be trip rates, assumptions about internal trips, TSM, and other factors which would affect this file. It will be presented in a clear, concise manner in laymen terms. The City will be permitted one round of comments on the results of the report. If additional response to comments were necessary, the City would be charged on a time and materials basis for the work. Fee and Schedule WSA proposes to complete PHASE I of this project for a fee not -to -exceed $16,850 (see attached Detailed Cost Estimate). If additional counts are added to the study, this fee would be affected. Actual billing will be done on an hourly basis using a multiplier of 2.65 times payroll costs (salary plus benefits). This assumes that no additional intersections will be added to the traffic model. The data collection aspect of this phase will be extensive and may take as many as three weeks. The entire project phase could be completed within six weeks. Prior to beginning work, WSA would like to receiving written notification to proceed. The six week schedule is contingent upon receiving the items identified in Task 3 of this scope within three weeks of project initiation. H you have any questions or comments regarding this scope of work, please do not hesitate to call me or Bill Hurrell. I can be reached in WSA's Oakland office (836-8901). Bill can be reached in San Francisco (896-0670). I look forward to hearing from you about this project and I am excited about the prospect of working with you on this and future projects in the City of San RafaeL Very truly yours, WILBUR SMITH ASSOCIATES .-I&d +4c' Mark J.
