Peter Vorametsantll Acting Manager Engineering & Construction Services City of Redwood City 1017 Mlddlefleld Road Redwood City, CA 94063 Via E-mail: pvorametsantl@redwoodclty.org Subject: Proposal to Amend the Contract Scope of Work and Budget to Develop a Citywide Traffic Model for the City of Redwood City Dear Mr. Vorametsantl: TJKM has been working diligently with City Planning and EngIneering staff and General Plan consultants during recent months to develop the citywide traffic model and produce the traffic forecasts that are needed for the preparation of the new General Plan and Its EIR. In mldMMarch, after review and authorization by City staff, TJKM provided the calibrated Existing (2008) conditions model and the UNo Project" (1990 General Plan) model for year 2035, as well as volume forecasts from those models, to Fehr & Peers Associates for use In the General Plan analyslsl and to Hexagon consultants for the Stanford Campus Extension traffic Impact study. In early April, TJKM receIved the land use data for the new 2009 General Plan "Project" and two alternative scenarios for year 2035, and withIn one week provided the model forecast results to City staff for review and authorlzatl9n to release to Fehr & Peers. We are currently preparing to run the "Cumulative" General Plan scenario based on land use data provided by City Planning staff and our discussions with them regarding roadway network assumptions. The nature of some of the transportation Infrastructure Improvements proposed In the new General Plan alternatlvesl and the transportation network to be assumed In the Cumulative scenario, requires analysis and preparation beyond what was anticipated In our original scope of work and budget. We also anticipate that the City will request TJKM to provide continuing on-call model support services and additional model forecast runs In the Immediate future. These addItional scope Items are summarized as follows. Analysis and Preparation of Transit Improvements In New General Plan Alternatives The 2009 General Plan "Project" and the two alternatives propose a new streetcar system and a ferry terminal (as well as some roadway network modifications). Modeling these major transportation Infrastructure Improvements dictates additional analysIs well beyond the future roadway network modlflcatlons anticipated In our scope of work. Modeling the streetcar system dictates that TJKM and City staff deflne the fundamental assumptions for a system of three streetcar routes, along Broadway, Seaport, and Mlddlefleld, Including the detailed streetcar route locatlonsl appropriate vehicle-trip reductIons along those routes, and an "area of Influence" radius aro'und them withIn which such trip reductions could be reasonably expected. TJKM uses these assumptions to adjust the trip generation for the traffic analysis zones (TAZ's) within the streetcar routes' area of Influence for the three 2009 General Plan alternatives. Additionally, one of those alternatives, uReduced Build Out," assumes streetcar routes on Broadway and Seaport, but not on Mlddlefleldl requIring a different set of model adjustments.
