Stormwater Division

The federal Clean Water Act’s National Pollutant Discharge Elimination System regulations govern storm water discharges from small cities/municipalities (such as Paso Robles) that operate storm drain systems. 

The State Water Resources Control Board and the Central Coast Regional Water Quality Control Board are responsible for enforcing stormwater regulations for the City of Paso Robles.

Streets and Stormwater_web (80)What is stormwater and why is it important?
Stormwater refers to the water that originates from rainfall or melting snow and flows over surfaces like streets, sidewalks, and rooftops. Instead of being absorbed into the ground, it collects and runs off into nearby drains, rivers, or other water bodies. Stormwater can carry various pollutants and contaminants from the surfaces it flows over, which can negatively impact the environment if not managed properly. Proper stormwater management aims to control and treat this runoff to protect water quality and prevent flooding.
