Stormwater and urban runoff from impervious (hard) surfaces like streets, sidewalks, parking lots, roofs, and driveways are major sources of creek and ocean water quality pollution.
Runoff from parking lots often contains pollutants including hydrocarbons, fine sediments, polycyclic aromatic hydrocarbons (PAHs), metals, nutrients, and other pollutants that are toxic to aquatic life and potentially harmful to human health.
By retrofitting existing infrastructure using Low Impact Development (LID) designs, stormwater is allowed to soak into the soil, mimicking pre-development conditions. By installing LID projects throughout the City, the amount of pollutants being carried directly into our storm drains, creeks, estuaries, and ocean will be reduced, improving water quality.
Permeable Paver Demonstration Projects
The Creeks Division is working to install permeable pavers in City-owned parking lots in several locations, in order to allow storm water and urban runoff to infiltrate into the ground. These projects demonstrate a retrofit that complies with the City’s Storm Water Management Program (SWMP) requirement to detain and treat the volume of water generated from a one-inch, 24-hour storm event.
