This service provides access to the precinct mapping information maintained by the Clerk-Recorder office for election purposes. Geographical information systems (GIS) technology has been used to maintain precinct boundaries and facilitate map printing. Precinct maps utilize GIS data imaintained by various county departments and agencies (Public Works, Assessor, Planning & Building, Cities, LAFCO, the Citizens Redistricting Commission, and the Census Bureau).
New U.S. Congressional, State Senate, State Assembly, and County Supervisorial, district boundaries as a result of the redistricting processes completed in December 2021 have been added to PrecinctView. Clerk-Recorder staff are working to modify precinct boundaries to conform to the new boundaries and to update local and state systems accordingly. Updated precinct maps are expected to be available by mid-February 2022. Please contact the elections team at [email protected] or 805-781-5228 with any questions. Thank you for your patience while we complete this once in a decade work.
