Storm Water

Municipal Waterways Maintenance Plan

The City of San Diego is responsible for a storm drain system that conveys runoff from local neighborhoods to the Pacific Ocean. Portions of the storm drain system require periodic maintenance to remove accumulated sediment, vegetation and trash that impedes water flow and increases flood risks. The City’s former Master Storm Water System Maintenance Program (MSWSMP) described the process for planning and performing maintenance activities. That program expired in 2018.

The City has developed a new Municipal Waterways Maintenance Plan that will guide maintenance of the storm drain system following the expiration of the MSWSMP. This plan has been adapted to more efficiently provide public safety through a pro-active and responsive maintenance schedule that minimizes and mitigates effects on the environment; and streamlines subsequent authorizations.

The Municipal Waterways Maintenance Plan includes:
