LSA ASSOCIATES, INC. SEPTEMBER 2016 ROCKETSHIP REDWOOD CITY ELEMENTARY SCHOOL PROJECT INITIAL STUDY/ MITIGATED NEGATIVE DECLARATION P:\RWC1401B Rocketship School\PRODUCTS\IS-MND\Public\Rocketship Public Review 09-29-16.docx (09/29/16) PUBLIC REVIEW DRAFT 65 f) Otherwise substantially degrade water quality? (Less-Than-Significant Impact) The potential for the construction and operation of the proposed project to degrade water quality is described in Section IX.a. No additional impacts to water quality would be expected. Therefore, this potential impact is less than significant. g) Place housing within a 100-year flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map? (No Impact) The project site does not involve the development of housing and is not located within a 100-year flood hazard area as mapped by the Federal Emergency Management Agency (FEMA)81. Therefore, no impact related to the placement of housing within a floodplain would occur. h) Place within a 100-year flood hazard area structures which would impede or redirect flood flows? (No Impact) The project site is not located within a 100-year flood hazard area as mapped by FEMA,82 and therefore no impact related to the placement of structures within a floodplain would occur. i) Expose people or structures to a significant risk of loss, injury or death involving flooding, including flooding of as a result of the failure of a levee or dam? (Less-Than-Significant Impact) The project site is not located within the inundation zone of the Lower Emerald Lake or within the inundation zones of any other water bodies near Redwood City.83 Additionally, the project site is not located within an area that is protected from flood by a levee.84 The project site could be subject to flooding as a result of sea level rise. In the San Francisco Bay area, the background rate of sea level rise has been estimated to be approximately 0.076 inches per year from 1900 to 2008, and a sea level rise of 16 inches by 2050 and 55 inches by 2100 has been predicted by the San Francisco Bay Conservation and Development Commission.85 The project site is located in an area that would be subject to flooding as a result of a sea level rise over 48 inches.86 The Redwood City General Plan and San Mateo County General Plan include multiple policies and programs specifically designed to address the effects of climate change within the confines of the City and County, respectively. In particular, Program PS-16 of the Redwood City General Plan states that the City will prepare response strategies that address climate change induced sea level rise and 81 Federal Emergency Management Agency, 2012.
