The San Bernardino County Registrar of Voters Precincts layer delineates the geographic boundaries of voting precincts within the county. Each polygon represents a unique precinct used in elections planning and logistics. Precinct boundaries are based on jurisdictional and district boundaries as defined by law and are essential for determining voter eligibility, ballot content, and polling place assignment. This dataset is utilized in various ROV tools, public-facing applications, and internal workflows.
The layer is maintained by the San Bernardino County Registrar of Voters ROV in coordination with San Bernardino County Innovation Technology Department – Geographic Information Systems Team (ITD–GIS).
