Special Districts Mapping Project

CSDA, in partnership with California CAD Solutions, is proud to present the most comprehensive, interactive map of independent special districts in California. CSDA’s goal is to have every special district headquarters and boundary lines represented on the map. If your district’s data is inaccurate or missing boundary lines, please let us know how we can correct it. Contact CSDA Member Services ( with any questions or comments.
The Special District Mapping Project is supported in part by contributions from the California Special Districts Alliance, a collaborative partnership between CSDA, CSDA Finance Corporation Special District Risk Management Authority (SDRMA).
