CaIVTP Project-Specific Analysis and Addendum C-9 'I►,; I Augustin Bernal Community Park Fuel Reduction November 2025 • Manual Treatment: Use of hand tools and hand-operated power tools to cut, clear, or prune herbaceous or woody species • Prescribed Herbivory:Use of domestic livestock to reduce a target plant population,thereby reducing fire fuels or competition of desired plant species • Herbicides: Chemical application designed to inhibit growth of target plant species PD-3.2.1: Prescribed Burning(Broadcast) Prescribed understory fires would mimic periodic low-intensity wildfires historically prevalent in the region and create similar structural and habitat conditions that benefit many plant and wildlife species.Gradual reintroduction of fire presents an opportunity to improve forest health, reduce critical fuel loading, improve emergency access, and regenerate a healthy ecosystem. Prescribed low-intensity surface fires (broadcast burning) would be used to control vegetation and manage fuel loads. Prescribed burning would remain within a predetermined area and would occur only with specific fuels and in safe weather conditions. Prescribed burns would be used for maintenance of treatments, and they would occur approximately every 5 years, as appropriate. Active burns would follow environmental safety guidelines, including burning only after consideration of specific weather conditions(e.g.,appropriate humidity,wind direction,etc.)and coordinating with resource agencies,such as the California Air Resources Board (CARB). Specifically, active burns would include the preparation and implementation of a burn plan, including a smoke management plan (SMP).The Project Proponent would report site conditions and request approval to burn through the Prescribed Fire Information Reporting System (PFIRS), which serves as an interface between air quality managers, land management agencies, and individuals that conduct prescribed burning in California. A prescribed burn SMP must be submitted to and approved by the Bay Area Air District (BAAD) at least 30 days prior to burning. Prescribed burns would typically be ignited using a flamethrower from a side-by-side utility terrain vehicle, by walking with a drip torch or fusee, or via other methods, as determined by a professional. Prescribed burns are typically completed in a single day but, under certain circumstances, could be maintained for up to 1. week. On average, up to 45 workers are present on-site for a prescribed burn. Heavy equipment would typically be operated from an existing road. In anticipation of completely avoiding the federally threatened Alameda whipsnake and minimizing habitat impacts for this species on the project site, prescribed burning within highly suitable Alameda whipsnake habitat would be restricted between November 1 and March 31 or when temperatures are conducive to snake movement,which is typically when soil surface temperatures reach or exceed 66°F (19°C). PD-3.2.2: Mechanical Treatment Mechanical treatments would mow target vegetation with special care to avoid ground disturbance in sensitive habitat. Lawn mowers,or similar,would target vegetation, including standing and downed vegetation. Mechanical treatments would also be employed as a biomass disposal method to chip and broadcast woody debris. Chipping and broadcasting equipment would typically remain on existing roads and fire trails. Mechanical treatment activities would occur predominantly on slopes below 40 percent grade and along ridges,and may occur on slopes
