City of Pleasanton—Hidden Canyon Residences and Preserve Biological Resources Draft EIR 3.3-30 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480016/EIR/3 - Draft EIR/21480016 Sec03-03 Bio Resources.docx amphibians from entering the work area. Barrier fencing shall be removed within 72 hours of completion of work. • No monofilament plastic shall be used for erosion control. • Construction personnel shall inspect open trenches in the morning and evening for trapped amphibians. • A qualified Biologist possessing a valid Endangered Species Act Section 10(a)(1)(A) permit or Service approved under an active biological opinion, shall be contracted to trap and to move amphibians to nearby suitable habitat if amphibians are found inside fenced area. • Work shall be avoided within suitable habitat from October 15 (or the first measurable fall rain of 1 inch or greater, to May 1). In addition, the EACCS specifies that a project shall obtain an Incidental Take Permit if occupied habitat is adjacent to the site and suitable habitat is on the project site. Compensation The project proposes to preserve in perpetuity approximately 104.6 acres of the project site as open space outside of the grading envelope. This amount of open space would more than sufficiently compensate for any loss of CRLF upland habitat. Additionally, to ensure that mitigation habitat meets or exceeds the value of the habitat lost to development. Additionally, Focal Species Impact/Mitigation Scoring Sheets, located in Appendix E of the EACCS, were used as part of the assessment for suitability of mitigation lands for CRLF. Standardized mitigation ratios for CRLF, according to Table 3-7 in the EACCS, are 3:1 if the development area is within critical habitat and 2.5:1 if the development area is outside of critical habitat. The vast majority of the development area of the project is outside of critical habitat; therefore, the proposed project is consistent with standardized ratios set forth by the EACCS for this species. An RMP shall be prepared explicitly to manage the proposed open space areas for potentially sensitive species potentially occurring. This plan will be submitted to the City for review and approval. At minimum, this plan should: • Identify approaches to be used and provide evidence that sufficient water budget exist for any proposed enhancement. • Identify a suitable planting regime for restoring or enhancing riparian habitats. • Identify success criteria for monitoring both wetland and riparian habitats that are consistent with similar habitats regionally. • Monitor restored or enhanced riparian habitats for 5 years. • Define and identify maintenance and management activities to manage open space habitats to meet stated goals of supporting habitat characteristics suitable for CRLF. This would include suitable fencing to control access, limited cattle grazing or other procedures to manage grass height and forage production at levels that benefit CRLF, removal of trash.
