Public Works locations are available in 311 cities across California. They are spread across 53 counties.

Cities with the highest concentration of public works offices include Los Angeles, Santa Clarita, Lancaster, reflecting larger municipalities with more extensive road networks, drainage infrastructure, and public facility inventories requiring dedicated public works staff.

Residents of California who notice road damage, drainage problems, or infrastructure hazards should report them to their city or county public works department as promptly as possible. Many departments in California have mobile apps or online portals that make submitting service requests fast and easy.
