Revamped supervisor district map promises significant changes for parts of Contra Costa

The new Contra Costa County supervisorial district map will likely move Diablo, Blackhawk and the Camino Tassajara area from District 3 Supervisor Diane Burgis’ purview to that of District 2 Supervisor Candace Andersen.

With one more public hearing scheduled before making a final decision, the board Tuesday unanimously endorsed a tentative map expanding Anderson’s reach to the east, placing the three Tri-Valley communities into the same district as Danville and San Ramon — cities with which they are already largely associated based on geography and demographics.
