Street Sweeping Pilot Study

The City of San Diego continues to explore new ways to help prevent storm water pollution. As part of this ongoing effort, the Storm Water Division conducted a pilot study of street sweeping options for neighborhoods adjacent to important waterways.

The study involved assessment of what kind of street sweeping equipment and sweeping frequency helped reduce the amount of pollutants on our roadways. Removing these pollutants keeps them from entering the storm drain system and flowing to our beaches and bays.

Kellogg Park Green Lot Infiltration Project

The California State Water Resources Control Board created Areas of Special Biological Significance (ASBS) to protect our oceans and prevent pollution within some of the most pristine and biologically diverse sections of California’s coast. La Jolla is home to two ASBS, which encompass a large portion of the La Jolla Shores marine environment. To protect the water environment off the coast, pollution and other waste discharges into the ASBS are prohibited by the California Ocean Plan.

Think Blue

One of the keys to cleaner ocean waters is public education. That is why the Storm Water Pollution Prevention Program developed the "THINK BLUE" educational campaign. "Think Blue" seeks to educate residents, businesses and industry about the causes of storm water pollution and about pollution prevention behaviors that they can adopt to help improve our water quality.
