This question was not included in the 1998 HVSP FEIR. No determination was made regarding the significance level of impacts related to infrastructure that may exacerbate wildfire risk. As previously discussed, the design of the proposed project and associated infrastructure would be consistent with the CBC and applicable provisions of the California Fire Code with regard to fire and emergency access and building materials, as well as the project’s conditions of approval pursuant to the 1998 HVSP FEIR, and the requirements of the General Plan Public Safety Element for areas within a special fire protection area. Therefore, impacts related to infrastructure that could exacerbate fire risk would be less than significant. The proposed project would not result in any peculiar effects and would not result in new or more severe impacts related to the project’s potential to expose occupants to pollutant concentrations from wildfire beyond what was previously analyzed in the 1998 HVSP FEIR. d) Flooding and Landslide Hazards Due to Post-fire Slope Instability/Drainage Changes Would the project: If located in or near State Responsibility Areas or lands classified as very high fire hazard severity zones ,expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes? Define impact. This question was not included in the 1998 HVSP FEIR. No determination was made regarding the significance level of impacts related to post-fire slope instability or drainage changes. The proposed residential units would be constructed in compliance with the California Fire Code with regard to access and building materials such as tile or other fire-resistant roofing. All driveways and internal roadways would be designed in accordance with the City’s Standards and Specifications guidebook to accommodate large emergency vehicles such as fire engines. The project site is located in the Moderate to High Fire Hazard Zones in the SRA 67 and is located in Zone X, an area of minimal flood hazards.68 Additionally, the 2015 Geotechnical Report indicates that numerous landslides have been mapped within or immediately adjacent to the project site. Although the FEMA flood hazard maps indicate that the project site is not located within a flood- prone area, portions of the Happy Valley Creek are known to experience occasional localized 67 California Department of Forestry and Fire Protection (CAL FIRE). 2007.
