Sequoia Ecological Consulting, Inc. CalVTP Project-Specific Analysis and Addendum Augustin Bernal Community Park Fuel Reduction November 2025 4-90 4.15.1. Discussion 4.15.1.1. Impact UTIL-1 The proposed project would include the following treatment activities: prescribed burning (pile and broadcast), mechanical treatment (mowing, chipping and broadcasting vegetation), manual treatment (using hand tools and hand-operated power tools such as hand saws, pole saws, McLeods, brush cutter, etc.), targeted herbicide application, and biomass disposal. A minimal amount of water would be required for fire suppression during prescribed and pile burning activities and for dust control during mechanical treatments. Depending on the location of the prescribed burning, pile burning, or mechanical treatments, water would be supplied via nearby fire hydrants or be transported via fire trucks. The CalVTP PEIR found increased water demand for vegetation activities to be a less-than-significant impact because vegetation treatments use minimal water and rely on existing sources without straining local supplies. The Project’s impacts are consistent with those analyzed in the PEIR because the amount of water required for prescribed burning and dust control is within the scope of activities and impacts determined in the PEIR. Due to the minimal amount of water required for these treatment activities, there would be minimal water demand on local water providers. No SPRs are applicable to this impact. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. The proposed project includes approximately 93 acres of land that is outside the CalVTP treatable landscape in the proposed treatment area, which constitutes a change to the geographic extent presented in the PEIR. The conditions outside the treatable landscape area are similar to those within it, primarily because they rely on the same water service providers and usage patterns. As such, the potential impacts are already addressed by the PEIR and would be considered a less than significant impact. No SPRs are applicable to this impact. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. 4.15.1.2. Impact UTIL-2 Mechanical and manual vegetation treatments would generate organic woody biomass as a result of vegetation removal within the project treatment areas. Methods for managing biomass for the Project include natural decomposition (e.g., chip and broadcast, lop and scatter), chipping and hauling, and pile burning. Any biomass not broadcast on-site or pile burned would be taken off-site to an appropriate biomass-processing facility, such as the Pleasanton Garbage Service, Inc. The CalVTP PEIR found that solid waste generation from vegetation treatments would be less than significant because most biomass is either left on-site, burned, or reused (e.g., for mulch or energy), and any waste generated is minimal and managed in compliance with state disposal standards. The potential biomass impact is within the scope of
