The Portneuf Greenway Foundation’s mission is to create a network of paved bicycle and pedestrian trails throughout the greater Pocatello Chubbuck area to enhance the quality of life for residents and visitors by establishing and improving the Portneuf Greenway as a community resource. The foundation is a 503(c) organization established in 1992 and is governed by a volunteer board of directors. The Foundation has no paid employees and receives no direct funding from the City of Pocatello or Chubbuck for public facilities.

Development of the Portneuf Greenway is guided by the Portneuf Greenway Master Plan and a supporting Capital Investment Plan. Though the Greenway Foundation focused on establishing trails along the Portneuf River initially, the broader vision is to connect a comprehensive trail system throughout the Pocatello and Chubbuck communities respectively. Several trails have recently been established along the I-15 corridor, the South Bannock Overpass, as well as in and around the Edson Fichter Nature Area in South Pocatello. Since 2014, the Portneuf Greenway Foundation has been the recipient of approximately $7.5 million in grants, public and private contributions, gifts and in-kind construction.
