Biological Opinion: Interstate-405, State Route 520 to Interstate-5 Improvement Project, King and Snohomish Counties, Washington. Endangered Species Act - Section 7 Consultation

摘要

The Washington State Department of Transportation (WSDOT) and Federal Highway Administration (FHWA) propose to construct safety and mobility improvements along approximately 15 miles of Interstate-405 (I-405), between the State Route 520 (SR 520)/I-405 Interchange in Bellevue (King County), Washington, and the I-405/Interstate-5 (I-5) Interchange in Lynnwood (Snohomish County), Washington. The project will require a Clean Water Act section 404 permit. Federal funding and issuance of a section 404 permit establish a nexus requiring consultation under section 7(a)(2) of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531 et seq.)(Act). The U.S. Fish and Wildlife Service (Service) based this Biological Opinion (BO) on the following sources of information: the Biological Assessment (BA), dated August 2007 and received on September 7, 2007; WSDOT and FHWA responses to our requests for additional information (written correspondence received on December 11, 2007, March 4 and March 27, 2008); a field review of the project site; and, various scientific literature and personal communications cited and referenced herein. A complete record of this consultation is on file at the Western Washington Fish and Wildlife Office in Lacey, Washington.
