Hall Equities Group is pleased to announce that the Walnut Creek City Council approved a plan to build 254 units of senior housing and a 136-bed residential care facility on 9.49 acres in Shadelands Business Park at the former Joint Genome Institute site at 2800 Mitchell Drive. The site and its five one-story buildings, which will be demolished, was originally built by Dow Chemical in the 1960s. The project required the council to agree to amend its general plan to change the site’s zoning from business park to mixed use residential. The housing will include four buildings, courtyards, and a small recreation building. Two buildings would be three stories, and two would be four stories. The three-story care facility will be licensed by the California Department of Social Services to provide housing for people 62 years and older who need assistance, but not 24-hour medical care.
