Appendix A - EIR Noticing and Public Involvement COMBINED

Hidden Canyon Residences and Preserve Project EIR City of Pleasanton Notice of Preparation • Biological Resources-The project sponsor's biological evaluation found potential for several special-status species on the project site, including California red-legged frog, Alameda whipsnake, golden eagle, western burrowing owl and American badger. Congdon's tarplant was also found within the project site footprint and open space area. Jurisdictional waters including Devaney Creek and a tributary, as well as isolated seasonal wetlands, are also located on-site. The EIR will include analysis of potential impacts on relevant special- status species and sensitive habitats. • Cultural and Tribal Cultural Resources -The EIR will include a summary of the applicant-prepared cultural resources and historic architecture report, and will also summarize tribal cultural coordination to confirm whether the project would potential affect any resources of importance to local tribes. • Geology and Soils -The project site is not located within in anAlquist-Priolo Fault zone. However, the applicant-prepared geotechnical report includes a number of recommendations for site preparation and foundations. The EIR will include an evaluation of site soils and geology and all recommendations from the geotechnical report will be included as mitigation measures. • Greenhouse Gas Emissions and Energy -The EIR will include an evaluation of construction-period GHG emissions to assess consistency with the City's Climate Action Plan. The EIR will also include an evaluation of operational-period emissions to assess compliance with BAAQMD thresholds. • Hazards, Hazardous Materials, and Wildfire -The project includes planned dedication of acreage to EBRPD for permanent preservation as open space land, and these lands could be subject to wildfire. In addition, the project site is located adjacent to additional open space lands. Wildfire risk and other potential hazardous materials will be evaluated in the Draft EIR. Additionally, emergency response and evacuation impacts will be reviewed, including the proposed emergency vehicle access road internal to the project site. The EIR will identify impacts and mitigation for hazards, hazardous materials, and wildfire. • Hydrology and Water Quality -The proposed project would involve grading and creation of new impervious surfaces that have the potential to create runoff that may affect on-site waterways, including Devaney Creek. • Land Use and Planning-As previously described, the proposed project would include annexation of land into the City of Pleasanton and General Plan amendments to reflect the proposed residential development. Conformity with Measures PP/QQ and other City policies will be evaluated as part of the analysis. • Noise -The EIR will include an evaluation of construction-period noise based on the estimated equipment list and duration of construction activities. Operational traffic noise impacts will also be evaluated. FirstCarbon Solutions 5
