7.A. - Page 36 Summary of Impacts Potentially Less than Significant Less than Significant With Mitigation Significant No Im act Incor orated Im act Im act XVL TRANSPORTATION/TRAFFIC -- Would the project: a) Cause an increase in traffic that is substantial in relation to the e�sting traffic X load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle trips, the volume-to-capacity ratio on roads, or congestion at intersections)? b) Exceed, either individually or cumulatively, a level of service standard X established by the county congestion management agency for designated roads or highways? c) Result in a change in air traffic patterns, including either an increase in traffic X levels or a change in location that results in substantial safety risks? d) Substantially increase hazards due to a design feature (e.g., sharp curves or X dangerous intersections) or incompatible uses? e) Result in inadequate emergency access? X fl Result in inadequate parking capacity? X g) Conflict with adopted policies, plans, or programs supporting alternative X transportation (e.g., bus turnouts, bicycle racks)? Documentation a. & b. The DTPP EIR (pp. 9-48 through 9-79) identified significant and unavoidable impacts at 17 area intersections, as well as impacts on freeway segments, freeway ramps, and transit service. Mitigations were suggested by the EIR, but the Redwood City City Council determined that such impacts could not be avoided even with the incorporation of these measures, and that no other feasible mitigations or alternatives would avoid or lessen the impacts. Furthermore, the City Council judged that the benefits offered by the DTPP outweighed the potential environmental impacts and adopted a Statement of Overriding Considerations to that effect. The proposed project is in compliance with all applicable DTPP regulations, and as a result, would not create arry additional transportation or traffic impacts in excess of those addressed by the DTPP EIR and Statement of Overriding Considerations. The project will be required to contribute to the City's Transportation Impact Fee, which is used for various sidewalk, bicycle, and automobile improvements that are identified in Book III of the DTPP. Also, the project will provide improvements to the sidewalk areas along all of the site's street frontages to enhance pedestrian comfort and safety by adding new plazas, paving surfaces, shade trees, street furnishings, lighting, and ADA crosswalk ramps (Plan Sheets L1.1 and Ll. 2, 4/26/13). The DTPP (New Streets Map, p. 56) indicates (1) a future roundabout ("Depot Circle ) at Middlefield Roacl/Hamilton Street and (2) a future extension of Harrzson Avenue through the project site. The City is no longer pursuing these facilities because they would not be conducive to the high level of pedestrian movement and activity anticipated at these locations; this policy consideration is consistent with the overall Community Intent & Guiding Principles of the DTPP (Book I). The City will be making minor amendments to the DTPP which will remove the requirements for these two facilities. Based on the study intersection and trip distribution analyses in the DTPP EIR (chapter 9, Transportation and Circulation), these minor amendments would not result in substantial changes to vehicular traffic volumes and patterns in the area primarily because neither of the two facilities nor their planned connecting streets (which would have been one travel lane in each direction) would have been designed to substantially redistribute traffic away from the nearest DTPP EIR study intersections of Middlefield/,Iefferson and Franklin/,Iefferson (DTPP pp. 56 though 58). A supplemental, project-specific traffic analysis was performed by Fehr & Peers transportation consultants which confirms that the project will result in no impacts beyond those addressed in the DTPP EIR. c. The project will not result in a change in air traffic patterns at San Carlos Airport or arry other airport, including either an increase in air traffic levels or a change in location that results in substantial safety risks.
