Biological Analyses Based on the site surveys conductcd by Sycamore Associates - "Biological Assessment and Ju- risdictional Determination for the 30-Acre Austin Property, Pleasanton, Alameda County, Cali- fornia" - and by WRA Environmental Consultants ("Rare Plant Survey Report, Austin Prop- erty, Pleasanton, Alameda County, California "), there are no endangered, threatcned, or rare species of flora or fauna known to inhabit the project site, nor is the project site considered to be habitat area for said specics, Thc tree survcy/analysis for this sitc prepared by HortScience, Inc., is attachcd. All existing trees on the caretakcr's property will be retained, This site will be subject to its own tree analy- sis with any application to redevelop this site. Tree #126, shown on Figure 3 on Pagc 3, is a 59- inch diameter valley oak in poor condition due to decay, "epicormic" sprouts, a huge cavity, etc., and will bc removed with development. Topography Moderate to steep terrain with a mix of grassland and native vcgetation including coast live oak, valley oak, acacia, and bluc gum eucalyptus trecs characterize the subject property. The sitc slopes upward from Old Foothill Road from an elevation of 380 feet to an elevation of 470 feet. From its lowest to highest points, the site slopes upward from 360 feet to 520 feet. The area westerly of the site from its northwest boundary line to Pleasanton Ridge is characterized by steeply sloped, tree-covered tcrrain, Figures 2 through 4 on the following pages are photographs ofthe Austin property and thc cxisting caretaker's homc. A series of ephemeral creels/swalcs/seeps drain the entire Austin property to the Arroyo De La Laguna and eventually to Alameda Creek and the San Francisco Bay, Thc three swales/seeps located along the northerly side of Lots 6 and 7, the southerly side of Lots 1 through 5, and be- tween Lots 1 through 5 and the access street arc subject to the jurisdiction of the United States Army Corps of Enginecrs, thc California Regional Water Quality Control Board, and the Cali- fornia Departmcnt of Fish and Game, and may rcquirc permits from these agcncies before the City issues grading permits for the project. These swales/seeps are shown on Figure 6 - Pro- posed Development Plan, Figure 7 - Conceptual Landscape Plan, and Figure 8 - Grading/ Drainage Plan.
