Cordilleras Mental Health Center Replacement

Situated in a valley surrounded by open space and trails, the $105M project includes five new buildings, including four single-story mental health recovery centers, each accommodating 16 clients, and a three-story co-housing building for 57 residents.

The mental health recovery buildings are wood framed and bear on mat foundations. The co-housing building is two stories of wood frame construction over a concrete podium and is founded on drilled piers. Project included design of retaining walls up to 20 feet tall and a foundation system for a 300,000-gallon water tank situated on a sloping hillside.

Civil improvements include circulation and fire access improvements on both sides of Cordilleras Creek, site grading to support the proposed buildings, an on-site stormwater treatment and detention system, undergrounding of a north tributary and realignment of the existing 30” Cordilleras Creek storm drain culvert. Additionally KPFF realigned existing domestic and fire water mains to/from the water tank, and extended sanitary sewer and water utility services to the proposed buildings.

The expansion is a construction management at risk design-build project.
