Protecting Against Floods

Street Sweeping

Street sweeping helps prevent pollution from getting into storm drains and protects communities against flooding. Learn more about the City's Street Sweeping Program.

Cleaning Storm Drains

Stormwater crews regularly clean and maintain storm drains year-round and take additional precautions when rain is in the forecast to protect San Diegans from flooding.

Clearing Channels

The Stormwater Department is responsible for maintaining the channels that carry rain runoff from San Diego's neighborhoods to the Pacific Ocean. This work requires proactively removing sediment, trash and other debris from channels to lower the risk of flooding.

Preventing Pollution


The Stormwater Department has inspection teams that work alongside local businesses to help them implement best managment practices and do their part to prevent pollution.

Monitoring Water Quality 

Samples are taken from over 500 locations across the City each year -- including rivers, creaks and the ocean -- to monitor water quality and keep waterways clean and safe.

Code Enforcement

Code Enforcement teams responds to complaints of illicit discharges (Municipal Code 43.0302) and inspect businesses to ensure compliance with permits and the law.
