County of San Diego
Green Stormwater Infrastructure Program
What may look like ordinary landscaping along roads or in parking
lots is actually carefully-engineered green infrastructure
built to capture stormwater, filter out the pollutants, and protect
local waterways!
Examples of green infrastructure include tree wells, planted medians
and walkways, and permeable pavements. Learn
more about the different types of green stormwater infrastructure.
