AUGUSTIN BERNAL MOUNTAIN BIKE TRAIL PROJECT DRAFT INITIAL STUDY 12956 DUDEK 86 April 2022 indirect effects associated with impairing implementation of emergency response or evacuation plans. Therefore, impacts from the project would be less than significant. b) Due to slope, prevailing winds, and other factors, would the project exacerbate wildfire risks, and thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire? The project site is located within a Very High Fire Hazard Severity Zone, as mapped by CAL FIRE (CAL FIRE 2021). Urbanized areas and existing development exist adjacent to the project site on the south and is surrounded by the existing Augustin Bernal Community Park to the north, west, and east. The project site currently supports an informal mountain bike trail on the site is frequently used by the general public. The City would perform vegetation treatments on the site to maintain the trail and defensible space requirements and reduce the potential for wildfire and would continue to perform these treatments following development of the project. The developed trail would be subject to vegetation management to further reduce the potential for wildfire ignition and spread, and the project would facilitate better access for emergency responders if a fire occurs. It is anticipated that the project would reduce the potential risk to people and property from wildfire and that no impact would result from increased fire hazard or pollution generated from wildfire. c) Would the project require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines, or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment? The project would rely on an existing road for access to the parking lot and access to the trailhead. The Project would not require the installation or maintenance of a new road, fuel break, utilities, or emergency water source. Vegetation maintenance and maintenance of defensible space would continue to occur as it does in the existing condition and impacts associated with elevated risk of fire as a result of park operations and maintenance would be less than significant. d) Would the project 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? The project site is located within a Very High Fire Hazard Severity Area Zone, as mapped by CAL FIRE (CAL FIRE 2021), Topography on site is highly sloped and would be subject to post-fire slope instability or landslides, rapid runoff, or drainage changes resulting in flooding if a fire were to occur. The project does not propose any structures that would expose people or other structures to significant risks and would not alter on-site topography in such a way that would increase the risks to off-site people or structures. As discussed above, the project would be expected to reduce the risk of wildfire occurring on the project site, and would therefore reduce associated post-fire risks related to geologic instability and changes in runoff. Impacts from changes resulting from the project would be less than significant. Mitigation Measures No mitigation measures are required.
