The District operates and maintains major flood control facilities such as dams, flood basins, levees, open channels and major underground storm drains. In most cases, the District does not maintain storm drain inlets or pipes less than 36 inches in diameter. These inlets and smaller facilities are typically maintained by city street departments or County Transportation Department.
Maintenance and Repair
The Project Maintenance section is charged with the daily maintenance and emergency repair of the District drainage system – a system consisting of over 420 miles of storm drains, open channels & levees along with nearly 40 dams and detention basins. Functions range from vegetation and rodent management, to fencing repairs and graffiti removal. The District's maintenance forces may only perform work on District facilities and within District property. To report a problem please call the District's Maintenance Office at (951) 955-1310 or (951) 955-1558. Storm drain inlets or catch basins are generally the responsibility of the local transportation authority. Residents of unincorporated county areas should report clogged storm drain inlets or catch basins to the County Transportation Department's Road Maintenance Section (951) 955-6899. City residents should call their city public works or street maintenance department. Problems related to grading or diversion of surface flows generally fall under the purview of the appropriate City or County Building and Safety Department.
