City of Redwood City Tra-- Mitigation Fee Study-Phase 11 Proposal- January 11, 1999 V.2 ReviewlRefine Traffic Projections We propose that the traffic analysis use both intersection and link traffic volumes to identify future traffic impacts. We will project future intersection turning movements at up to 25 intersections where traffic counts are available, and project link volumes at up to 15 locations where 24-hour counts are available. V.3 Conduct Traffic Analysis Using the traffic projections developed and refined in Task V.2 we will analyze future level of service and identify impacts based on standards adopted in earlier tasks. The analysis will differentiate between impacts caused by Redwood City development and regional or through traffic growth. This differentiation will be determined using "select link" capabilities of the C/CAG traffic model. As a result, we will identify the specific incremental impacts of Redwood City growth on intersection and roadway service levels. We propose to utilize micro-simulation (CORSIM) analysis on up to three complex situations (e.g. close proximity intersections, multi-leg intersections, etc.). Use ofthe micro-simulation model will be determined on a case-by-case evaluation. V.4 Develop Mitigation Measures The traffic analysis will identify areas and facilities impacted in Redwood City, and determine the traffic contributed to the facility by existing traffic, Redwood City growth, regional growth and through traffic growth. We will develop capital improvements to mitigate existing deficiencies and impacts caused by growth. To the extent feasible, the mitigation of existing deficiences will be the first stage of a staged improvement plan to mitigate growth, thus minimizing temporary solutions. We will prepare concept plans of mitigations (see Task VI) and present a list of preliminary capital projects to the City Council (not a workshop). We will document the traffic analysis, findings and capital improvement recommendations in a working paper. This task includes a meeting with City staff to present and discuss the working paper prior to presentation to the City Council. After receiving direction from the City Council and staff, we will refine and finalize the list of capital improvements. Task VI. Engineering Concepts and Cost Estimates VI.l Data Collection The consultant team will gather relevant data, and review and develop base maps and initial improvement concepts. We will obtain and review available material for capital improvement projects, including "as-builts", existing right-of-way maps, environmental documents, air photos, survey controls, utilities, etc. If necessary, we will create an inventory listing of additional information needed to complete the design. If necessary, we will obtain appropriate Caltrans right of way record mapping, Caltrans record drawings of state facilities, other Caltrans and City as-built information, adjacent land owner's plans, and other appropriate information as the basis for and to initiate mapping. We will obtain mapping of major utilities from appropriate utility companies. Fehr & Peers Associates, Inc. Page 7 ..._"_.'d"____'..-"'-".."'...'..- .....--.-.
