tion basins in conformance to Urban Stormwater RunoffRequirements, will be subject to City review and standards. The project developer would be required to be responsible for implementing a construction "Best Management Practice" during all construction phases of the project. The flood hazard maps of the Federal Emergency Management Agency (FEMA) indicate that the project site is not located within a flood prone area. X May be Insignificant Insignificant Significant if Mitigated 3.06 Plant and Animal Impacts (Effect on Existing Ecosystem, Rare or Endangered Spe- cies, Etc.): The subject property is characterized by rolling hillsides covered with grasses, shrubs, and numerous trees. Two biotic habitats dominate most of the site: · ridge tops and southerly facing slopes support primarily non-native grassland charac- teristic of grazing lands; and, · northerly slopes and canyon bottoms support areas of blue oak woodland (blue oak, valley oak, coast live oak, and California buckeye, with understory vegetation similar to that found in the grassland areas. Wildlife species include raptors and other bird species, red fox, California ground squir- rel, spotted skunk, black-tailed deer, etc., with the majority of wildlife inhabiting the site's more heavily vegetated areas. Although many of these areas would remain Undis- turbed by the proposed site development, some wildlife displacement is likely to occur. The site is also probable habitat area for threatened and/or endangered species, including red-legged frog, tiger salamander, etc. An issue for this proposal would be the amount and type of domestic herbicides, insecticides, fertilizers, etc., that would drain into the creek channel, swales, and gullies from private yards and streets and the effect that these materials would have on creek wildlife and habitat. A detailed analysis of flora, fauna, and habitat areas will be required to determine the proposed project's impacts and mitiga- tion measures. As stated in the preliminary tree report, "Tree Report for the Kottinger Hills Subdivi- sion'', dated October 8, 2003, prepared by Douglas E. Nix of Ralph Osterling Consult- ants, Inc., there are an estimated 12,000 trees - primarily blue oak, California buckeye, coast live oak, and valley oak species - located on the subject property with a total of 924 trees located within the project area. Of this number, 122 trees including 77 heritage-size trees would be removed with site development and another 59 trees including 44 heri- tage-size trees could be impacted. Normally, where heritage-size trees are removed with development, replacement trees of a similar species or variety of species is required. PUD-33, Initial Study Page 6 o fl 1 December 4, 2003
