On June 3, 2008, the Jimmy and Rosalynn Carter Partner Foundation announced Portland State as the recipient of The Jimmy and Rosalynn Carter Partnership Award for Campus-Community Collaboration for their Watershed Stewardship Program. The program has led over 27,000 community volunteers donating a quarter of a million hours to install 80,000 plants and restore 50 acres (20 ha) of watershed along two miles (3.2 km) of river.
