The project consisted of a new 314,500 square foot replacement hospital building for the County Hospital of Contra Costa.  The project site is located on a steeply sloping five acre hillside site within the twenty acre Contra Costa Regional Medical Center campus.  Site planning for the new hospital, drop-off, roads and parking carefully interfaces with the existing hillside slopes and buildings to maintain access to existing buildings, minimize grading and preserve specimen trees, including an historic grove of redwood trees.  Numerous retaining walls were designed to maintain existing topography and stands of existing native vegetation. A pedestrian walk, at the top of the hillside site, provides access to the emergency drop-off, emergency parking and campus satellite buildings.
