likely use CMP facilities (EI Camino Real, Woodside Road, US 101 and 1-280), Hexagon will prepare a TDM Plan as an optional task under this workscope. Scone Adiustments That Don't Reouire Budget Increases 6. Cumulative Scenario and Red Morton Park Westside Renovation Proiect: Hexagon had not previously been aware that the City's Westside Renovation Project for Red Morton Park is currently underway. Hexagon will coordinate with City staff to include the project trips estimated by the renovation project's consultant in the cumulative scenarios for this Traffic Impact Analysis. 7. Background Scenario: Hexagon will include trips from downtown development in the background scenario of the Traffic Impact Analysis, as requested by the City. Based on Hexagon's review of the Redwood City Downtown Precise Plan, the downtown development will generate trips at the project's study intersections on Jefferson Avenue, but not at the other study intersections. 8. Cumulative Scenario Growth Factor: Based on the City's feedback to Hexagon, Hexagon will use a 1.5 percent growth factor for volumes on Jefferson Avenue, since it is a collector/arterial. For the other streets, a 0.5 percent growth factor will be used. Hexagon will apply this growth factor for a five year period to obtain Cumulative scenario traffic volumes. 9. Trin Generation: Based on the City's feedback, Hexagon will revise its trip generation estimate. Of the total project's increase of approximately 37,000 square feet, about 35,000 square feet, or 93.5 percent, is attributable to the YMCA facility. Accordingly, Hexagon will apply the trip generation rates of the Senior Center and the YMCA, as determined by their respective driveway counts, to the increase square footage separately.
