City of Pleasanton—Hidden Canyon Residences and Preserve Project CEQA Findings of Fact and Statement of Overriding Considerations 34 FirstCarbon Solutions Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480016/FOF/21480016 Pleasanton Hidden Canyon Residences and Preserve Project FOF.docx Facts in Support of Findings: No Lead Agency-determined TCRs were identified during Tribal consultation efforts conducted by the City pursuant to Assembly Bill (AB) 52 on September 18, 2025, which was conducted in accordance with the criteria set forth in subdivision (c) of Public Resources Code Section 5024.1. The City sent consultation letters to each Tribe on the NAHC consultation list. To date, no responses requesting to consult have been received. Although the proposed project would implement the City’s standard COA CUL-3 to ensure consistency with Housing Element Program 5.3, out of an abundance of caution in the event TCRs are uncovered during project construction, the proposed project would also implement MM CUL-2. Through implementation of MM CUL-2, the proposed project would reduce impacts on Lead Agency-determined TCRs to less than significant. The Lead Agency finds that MM CUL-5 is feasible, is adopted, and will further reduce impacts related to Lead Agency determined TCRs. Accordingly, the Lead Agency finds that, pursuant to Public Resources Code Section 21081(a)(1) and CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the proposed project that mitigate or avoid the potentially significant impacts as identified in the EIR. Therefore, impacts associated with Lead Agency-determined TCRs would be less than significant with mitigation incorporated. 1.6.9 - Impact GEO-1: Seismic-Induced Ground Failure and Landslides Impact GEO-1: The proposed project would not directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury or death involving: i. Rupture of a known earthquake fault, as delineated on the most recent Alquist- Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault. Refer to Division of Mines and Geology Special Publication 42. ii. Strong seismic ground shaking. iii. Seismic-related ground failure, including liquefaction. iv. Landslides. Findings: Less than significant impact with mitigation incorporated. (Draft EIR, p. 3.6-28). Changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (CEQA Guidelines § 15091(a)(1)). Mitigation Measures MM GEO-1 Design-level Geotechnical Study Prior to the issuance of any building or grading permits, a design-level geotechnical investigation on the project site and review of detailed site plans shall be performed by a qualified Geotechnical Engineer. The design-level geotechnical investigation could incorporate a variety of field methods and would include (but not be limited to) the following items:
