• Abstract:
  The I-90 Snoqualmie Pass East Project (SPE) is located along a 15-mile stretch of Interstate 90 ; that passes through the Okanogan-Wenatchee National Forest. The project corridor has been ; identified as a critical connectivity zone for Pacific Northwest wildlife populations linking natural ; habitats both to the north and south of the project area. The Washington State Department of ; Transportation (WSDOT) will help alleviate the effects of increased traffic volume, a wider ; highway and increased traffic speed by enhancing ecological connectivity at 14 Connectivity ; Emphasis Areas (CEA) throughout the project area for multiple species and ecological processes. ; Wildlife monitoring is needed both prior to and following the installation of project mitigation ; measures to ensure that efforts to enhance ecological connectivity are achieving their intended ; goals. WSDOT contracted with Western Transportation Institute (WTI) to conduct preconstruction ; baseline wildlife monitoring within the I-90 SPE project area from 2008-2012. ; This baseline wildlife monitoring report addresses the collection of baseline data related to ; monitoring objectives. These objectives include: characterizing the rate and location of wildlifevehicle ; collisions, assessing the extent of sub-grade and at-grade crossings by wildlife, and ; assessing species occurrence within the Project Area. This report identifies survey methods and ; approaches, provides a review of monitoring achievements, and outlines future efforts required to ; ensure project success.
