Supervisors approve contentious senior care complex at Seven Hills Ranch in Walnut Creek

After hearing from at least 50 speakers — including two callers on other continents — spanning about six hours, the Contra Costa County Board of Supervisors unanimously approved the Spieker Senior Development residential care facility in unincorporated Walnut Creek.

Spieker will build 354 housing units within 30 single-story buildings, an 85,000-square-foot medical center, a multi-story clubhouse, a recreation building, a maintenance building, and a parking garage on the 30-acre site.
