channel and the 0.65-acre pond associated with Drainage"A" are jurisdictional wetlands. The 2.8-acre Area"C'at the north end of Patterson Run and small portions of Drainage"A" and "B"are determined to be jurisdictional "waters of the U.S." The site plan for the proposed ADT Auto Auction indicates that much of the Drainage"A"channel would be retained in its current state and would be surrounded by 10-foot-wide vegetative swales and curbs, set back approximately 25 feet from the channel. A small portion, approximately 3,000 square feet or 0.06 acre, at the eastern end of Drainage "A"is proposed to be filled. As noted above, the Patterson Run channel would be retained and fenced off along with the adjacent detention basin. No improvements have been proposed for the Drainage"D"channel or the pond to the north of the proposed parking area. Drainage"B" and the pond would be retained in their present state. Kit Fox and Burrowinq Owls The developer of the Patterson Pass Business Park was required to mitigate for potential impacts of development on two sensitive species, the San Joaquin kit fox and the burrowing owl. Mitigation included the purchase and granting of a conservation easement for 627 acres of kit fox habitat. The developer was also required to construct four artificial nests for burrowing owls in the northern portion of the property. The Development Agreement and conditions of approval for the project call for periodic monitoring of the site and pre-construction kit fox surveys for all new construction. These requirements will continue to apply to the project site. California Red Legged Frog California Tiger Salamander Diamond-petaled California Poppy, Large Flowered Fiddleneck In October 1999, LSA Associates conducted a habitat assessment and survey for the California red- legged frog, a Federally listed threatened species. LSA did not find any adult red-legged frogs or larvae and concluded that although this species is currently absent from the site, the southern half of the Patterson Run drainage provides suitable foraging, cover, and potential breeding habitat for the red- . legged frog. The site was also surveyed by Zentner&Zentner in October, 1999. Zentner &Zentner agreed that suitable habitat for the red-legged frog was'present in Patterson Run. The biologist also determined that the pond at the lower end of Drainage"B" may provide habitat for the California tiger salamander, a Federal listed candidate and a California species of concern. Zentner& Zentner also determined that the site is good potential habitat for two special status plant species, the Diamond-petaled California poppy and the large-flowered fiddleneck. The following permits may be required for the project: • One or more permits from the U.S. Army Corps of Engineers, including the following Nationwide permits(NWP): NWP14 (authorization for crossings);and NWP 26 (fill of Drainage"A"); • A 1603 Streambed Alteration Agreement from California Department of Fish and Game for crossings, outfall and intake structures, temporary construction access and/or dewatering, and fill of Drainage- "A"; • Consultation under Section 7 of the U.S. Endangered Species Act with the U.S. Fish and Wildlife Service for construction issues related to the California red-legged frog; and • A water quality certification under Section 401 of the U.S. Clean Water Act by the Central Valley Regional Water Quality Control Board, or a cerfification waiver.
