• 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.
