Precinct Maps

Precinct Mapping Resources

The Clerk-Recorder’s office has implemented GIS (Geographical Information Systems) technology in maintaining precinct boundaries and map printing.  This allows the use of data maintained by various county departments and agencies (Public Works, Assessor, Planning, Cities, LAFCO, the Citizens Redistricting Commission and the Census Bureau) when drawing precinct boundary lines.  The use of technology in these functions will result in more accurate and up-to-date maps.

Large format pdf maps (48” x 36”) are available free of charge for download. Maps of the entire county, supervisorial districts, cities, and major communities are available online.

Upon request, existing pdf maps can be burned onto a cd for $2. Printed versions of existing large format map must be ordered and cost $15 each.

Printing Instructions:  For best results when printing, select “Fit to Printable Area” under Page Scaling or in Printer Properties
