7.A. - Page 122 LSA ASSOCIATES, INC. ROCKETSHIP REDWOOD CITY ELEMENTARY SCHOOL PROJECT SEPTEMBER 2016 INITIAL STUDY/MITIGATED NEGATIVE DECLARATION c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks?(No Impact) The project site is located approximately 2.5 miles southeast of the San Carlos Airport and approxi- mately 13 miles southeast of the San Francisco International Airport(SFO),and is located within the Airport Influence Area(AIA)of both airports.112°113 The project site is not located near any private use airstrips. The project site is outside of Area B boundaries for both airports,which requires City/ County Association of Governments of San Mateo County Airport Land Use Committee review to ensure that the proposed allowable development is consistent with aviation safety requirements. The proposed project is outside the Area B boundary and the height of the building would not increase compared to existing conditions. The project would not install or construct any structure which extends into or above air space,or which constitutes an obstruction to air navigation,or which interferes with the use of flight air traffic patterns. Therefore,no impacts to air traffic patterns would result from the project. d) Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g.,farm equipment)? (Less-Than-Significant Impact) Site access, sight distance,and site circulation issues that could contribute to hazardous conditions are discussed below. In addition,drop-off and pick-up procedures and the potential for these activities to create on-or off-site hazards are also discussed. As discussed,these impacts would be less than significant.Minor modifications are however recommended to further ensure that the proposed project would not create a hazard due to a design or operational feature. Site Access.The Traffic Study(see Appendix F)included an evaluation of site access to determine the adequacy of the site's driveways with regard to the following: traffic volume,delays, vehicle queues,geometric design,corner sight distance,and truck access. Drop-off and pick-up would occur in the main school parking lot located along the eastern edge of the property. This lot would be served by two driveways,one each on Charter Street and Bay Road.Both driveways would be 24 feet wide,which meets the minimum driveway width set forth in the City's zoning code. During the peak pick-up/drop-off hours,the driveway on Charter Street would function as an inbound-only driveway,while the driveway on Bay Road would serve as outbound-only. Each of these driveways would have design widths and/or physical barriers to prevent more than one vehicle from entering or existing at any one time. School staff would be positioned at each driveway to restrict traffic entering and exiting these driveways to right turns only during these hours. During off-peak periods,the Charter Street driveway would be fenced and the Bay Road driveway would serve both inbound and outbound traffic. The proposed Charter Street driveway would be approximately 16 feet west of the crosswalk at Bay Road. The driveway would comply with City guidelines,which require a minimum of 15 feet between a curb cut and a crosswalk. 112 City/County Association of Governments of San Mateo County,2012,op.cit. 113 City/County Association of Governments of San Mateo County,2004,op.cit.
