Mount Baker-Snoqualmie National Forest (MBSNF or the Forest) is located in close proximity to the Puget Sound metropolitan area in western Washington State. The Forest is facing a number of transportation issues, such as increasing congestion and decreasing availability of parking, which may negatively impact resources and visitors. In 2008, the Forest received a Federal Transit Administration (FTA) planning grant to examine these issues by conducting an alternative transportation study. This report summarizes the results of the first of two phases of the study, which was conducted from May 2011 to January 2012.
