City of Pleasanton—Hidden Canyon Residences and Preserve <br />Draft EIR Executive Summary <br /> <br /> <br />FirstCarbon Solutions ES-14 <br />https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480016/EIR/3 - Draft EIR/21480016 Sec00-03 Exec Summary.docx <br />Impacts <br />Level of Significance Before <br />Mitigation Mitigation Measures Level of Significance After Mitigation <br />ground-disturbing activities in suitable <br />habitat. <br />• A qualified Biologist possessing a valid <br />Endangered Species Act Section <br />10(a)(1)(A) permit or Service approved <br />under an active biological opinion, and <br />approved by the CDFW shall be <br />contracted to trap and to move reptiles to <br />nearby suitable habitat if listed reptiles <br />are found inside fenced area. <br /> <br />Compensation <br />Clustering and siting of the project has also <br />allowed for in perpetuity preservation of <br />104.6 acres of open space of similar habitat <br />quality to the approximately 24 acres that <br />would be impacted by the project. This <br />amount of open space would more than <br />sufficiently compensate for any loss of <br />Alameda whipsnake upland habitat. <br />Additionally, Focal Species <br />Impact/Mitigation Scoring Sheets located in <br />Appendix E of the East Alameda County <br />Conservation Strategy (EACCS) were used as <br />part of the assessment for suitability of <br />mitigation lands for Alameda whipsnake. <br />Standardized mitigation ratios for Alameda <br />whipsnake, according to Table 3-9 in the <br />EACCS, are as follows: <br />1. If the development area is within critical <br />habitat and the mitigation area is within <br />critical habitat, and both are within the <br />same Recovery Unit (both areas in this <br />case are within Recovery Unit 3) the <br />mitigation ratio is 3:1.
