Cape Disappointment (formerly named Fort Canby State Park) has a vibrant history, including native peoples, explorers, US military and most recently state parks. The 1800-acre Washington State Park at the mouth of the Columbia River contains over two-hundred campsites, a boat ramp, day use areas, interpretive center and many historic coastal fortification structures. The environment is very dynamic, with coastal erosion threatening approximately ninety of the existing campsites. GreenWorks led a multi-disciplinary team in developing a 20 year Master Plan for the park, identifying new visitor service centers, administrative headquarters, maintenance facilities, multi-use trail network, interpretive facilities and restoration areas. In addition, GreenWorks oversaw the preparation of a Draft and Final Environmental Impact Statement.
