Draft Environmental Impact Report Bernal Property Phase II Specific Plan presence or potential for populations of special-status taxa; and identification of existing trees on the property that may be considered "heritage trees" according to City of Pleasanton criteria, The surveys also established a preliminary understanding of the extent of jurisdictional wetlands and "other waters of the U,S,"ll The data collected during these previous surveys for common plant and wildlife species and plant communities potentially present on the site remain applicable, This review focuses on changes in conditions since the earlier biological investigations, The earlier data has been updated to reflect (l) changes in the status of protected plant and animal species and (2) the potential for additional wildlife habitat to have been created on the property, The field visit conducted by the EI R biologist (October 20, 2005) focused on wildlife issues that may have changed since the previously-conducted field work. In the 2005 site visit, special attention was given to areas that may provide habitat for sensitive herpetofauna, such as the California tiger salamander ("CTS," Ambystoma tigrinum cafi[orniense) and the California red-legged frog ("CRLF," Rana aurora draytonii), b. Existing Conditions Figure 13 shows key biological resources of the Bernal Property Phase 2 Specific Plan site, Appendix D presents background information on biological resources, (1) Vegetation and Habitats Plant Communities Figure Dl (Appendix D) is a map from the 1997/2000 EIR showing vegetation and habitat on the Bernal Property as it existed prior to the Phase I development: . Arable Land and Non-native Grassland . Oak Savannah . Stock Pond . Willow Stand and Thicket . Ornamental Landscaping . Riparian Forest . Freshwater Marsh . Heritage Trees . Seasonal Wetlands The principal habitat type was cultivated animal feed crops (Western and Central Areas) and non-native grassland (Eastern Area), The earlier EIR also identified several trees of signifi- cant size in the annual grassland on the fringes of the agricultural fields, Where develop- ment has not already taken place, these communities are still present as mapped earlier, Water-Related Habitats Figure D2 (Appendix D) shows wetlands and other waters identified on the Bernal Property in the 1997/2000 EIR, These included the well-developed riparian woodland vegetation along the Arroyo de la Laguna in the Western Area and freshwater marshes along the unnamed tributary stream in the Eastern Area (line B-2-1 in Appendix D, Figure D2), 12 These earlier studies are identified and described in the 1997/2000 EIR on the Bernal Property Phase I Specific Plan (see PP, 275-281), 13 All Pleasanton Heritage trees are by definition 55" or greater. 56
