April 2022 Augustin Bernal Mountain Bike Trail Project Proposed Mitigated Negative Declaration for the Augustin Bernal Mountain Bike Trail Project Proposed Project The proposed project would develop an approximately 0.7-mile-long (3,700 linear feet) technical mountain bike trail within and adjacent to Augustin Bernal Community Park in the City in part replacing an existing unofficial user-created trail, and decommission 4,300 linear feet of other existing unofficial user-created trails. The new trail would consist of an appropriately designed and engineered trail to minimize erosion and user risks and reduce potential pedestrian/bicyclist conflicts on the multi-use trails in Augustin Bernal Community Park by encouraging some of the existing downhill mountain bike traffic currently using the multi-use trails to divert to the new trail. Other user-created trails would be decommissioned to minimize potential adverse effects to the vegetation and wildlife in the park. Construction of the proposed trail would require minor grading and vegetation clearing along the entire bike trail alignment. Decommissioning existing user-created trails would involve removing constructed features such as berms and jumps, rehabilitating soil, and broadcasting a seed mix to promote new vegetation growth. Refer to the attached Initial Study for additional project information, including figures of the project location, proposed trail alignment and design, proposed trails to be decommissioned, and existing site conditions. Environmental Analysis An Initial Study for the proposed Augustin Bernal Mountain Bike Trail project was prepared in accordance with CEQA (Section 21000 et seq., California Public Resources Code) and the CEQA Guidelines (Section 15000 et seq. Title 14, California Code of Regulations). The analysis in the Initial Study determined that the project could have potentially significant impacts to the following resource categories: Biological Resources, Cultural Resources, Geology and Soils, Hazards and Hazardous Materials, Hydrology and Water Quality, Public Services, Recreation, and Tribal Cultural Resources. The Initial Study identifies the following mitigation measures to address these potential impacts: Mitigation Measure BIO-1 - Special-Status Plant Compensatory Mitigation Mitigation Measure CUL-1 - Treatment of Unanticipated Cultural Resources Mitigation Measure CUL-2 - Treatment of Unanticipated Human Remains Mitigation Measure GEO-1 – Erosion Control Mitigation Measure GEO-2 - Treatment of Unanticipated Paleontological Resources Mitigation Measure HAZ-1 – Management of Hazardous Materials During Construction Determination As demonstrated in the Initial Study, the City finds that, with implementation of the identified mitigation measures, there is no substantial evidence that the proposed project would have a significant effect on the environment. Therefore, the City has prepared this Proposed Mitigated Negative Declaration for the Augustin Bernal Mountain Bike Trail Project for adoption following public review of the attached Initial Study and supporting documentation.
