AUGUSTIN BERNAL MOUNTAIN BIKE TRAIL PROJECT DRAFT INITIAL STUDY 2 Summary of Findings 2.1 Environmental Factors Potentially Affected This Initial Study analyzes the environmental impacts of the project consistent with the format and analysis prompts provided in Appendix G of the CEQA Guidelines. The analysis 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 analysis determined that all potentially significant impacts would be less than significant with implementation of mitigation measures to avoid or minimize the impacts identified. Detailed analyses of impacts are provided under each resource section evaluated by this Initial Study. 2.2 Environmental Determination The City of Pleasanton,as lead agency,finds that the Initial Study identifies potentially significant impacts, but that implementingthe mitigation measures identified in Table 2-1 would avoid or minimize the impacts such that they would be less than significant. The project would result in no impacts that would remain significant following implementation of mitigation measures.All mitigation measures are identified in Table 2-1, below, and throughout Section 3 Initial Study. Table 2-1. Mitigation Measures Measure Number Measure Text BI0-1 Special-Status Plant Compensatory Mitigation. If special-status plants and/or bunchgrass/wildflower stands cannot be avoided without compromising trail integrity (e.g., if plants are in a cut-fill area required for drainage or slope stabilization), compensatory mitigation for unavoidable permanent impacts on special-status plant occurrences shall be required based on recommendations of a qualified botanist. Given the amount of available habitat in Augustin Bernal Community Park, it is expected that compensatory mitigation could be accomplished at the park. Compensatory mitigation shall include the following components,at a minimum: • The botanist shall prepare a special-status plant mitigation plan that includes seed/propagule collection methods, success criteria, 5 years of maintenance and monitoring,and adaptive management approaches.The special-status plant mitigation plan shall be implemented to document the success of creation of the new plant occurrence. Adequate funding for compensatory mitigation shall be provided on an agreed-to schedule. • Prior to unavoidable and permanent disturbance to any special-status plants, propagules shall be collected from the occurrence to be disturbed.
