Welch Comer developed the River Ridge Redevelopment Master Plan for the City of Potlatch for 210 acres that was once a Potlatch Corporation saw mill. The project also included public facilitation, presentations, wetland delineation, soils investigation, and flood plain determination.
Funding for the project planning came from the Potlatch Corporation, USDA- RBEG funds and the City of Potlatch. The implementation strategy prepared by Welch Comer recommends a mixed-use site re-development, combining residential, commercial and recreational land use. The plan provides a five stage implementation strategy, with detailed estimates of infrastructure development.
