Many of the storm drains within the City of Arroyo Grande drain directly or indirectly to the Arroyo Grande Creek. That means that any pollutants and litter that get into the storm drain system end up in the Arroyo Grande Creek, and eventually the ocean, without any treatment.
Because storm water does not receive any treatment, it is especially important to keep all pollutants out of the storm drain system.
Help Stop Stormwater Pollution!
The City of Arroyo Grande is required to implement a Phase II Municipal Stormwater Program in order to reduce or eliminate the pollutants that enter the storm drain system, and our waterways, from both storm water and non-stormwater flows.
