City of Pleasanton—Hidden Canyon Residences and Preserve Biological Resources Draft EIR 3.3-18 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 Local East Alameda County Conservation Strategy The project site occurs within Conservation Zone (CZ) 8 of the EACCS study area.1 The EACCS document provides “context and guidance to project applicants, local jurisdictions with permit authority, and resource agencies in determining the potential impacts of a project and the level and type of mitigation necessary to offset those impacts.” This document suggests a standard mitigation ratio of 3:1 for impacted land, which may vary depending on type of habitat lost and type of CZ the project is within. There are 10 animal species and five plant species that are considered “focal species” of the plan, and standardized mitigation ratios are provided for each of these species for impacts based on individual species, the relevant CZ, and habitat quality scoring for impacted habitat and proposed mitigation habitat. Pleasanton General Plan The Pleasanton General Plan was adopted in 2009 and includes policies on Heritage Tree preservation and grading cessation when historic artifacts are found. These policies are listed below: Goal 1 Practice sustainability to preserve and protect natural resources and open space. Goal 2 Preserve and enhance the natural resources of the Planning Area, including plant and wildlife habitats, Heritage Trees, scenic resources, and watercourses. Policy 1 Preserve and enhance natural wildlife habitats and wildlife corridors. Program 1.1 Complete a comprehensive study of the ecosystems and wildlife habitat areas within and around the Planning Area and develop and implement ordinances and policies that will provide for their preservation and enhancement. Program 1.2 Identify land within the Planning Area which could be reclaimed as viable wildlife habitat. Study methods to re-establish viable plant and animal communities in these areas. Develop standards to accomplish habitat reclamation which: (1) specify the minimum acreage, topography, flora, fauna, and other characteristics necessary to ensure survival of wildlife habitat areas; (2) specify necessary length, breadth, flora, fauna, and other characteristics necessary to ensure the protection and use of wildlife corridors; and (3) prevent the creation of open space islands, unless they are connected through a series of viable wildlife corridors in accordance with specified standards. Program 1.3 Preserve and enhance the resource value of wetlands through project development design measures. These measures should be based in part on jurisdictional wetlands delineation in accordance with current Army Corps of Engineers criteria, for projects which are known to have or that may have wetlands present within their boundaries. 1 ICF International. 2010.
