What is Stormwater? 

Stormwater is rainwater runoff from rooftops, paths and roads collected by a system of pipes and drains. These flow directly to creeks and the bay without treatment.

Building, landscaping and industrial activities contribute to the heavy pollutants found in the stormwater system. These pollutants affect the water quality, kill aquatic life and degrade our beaches.

Everyone has an obligation to protect our waterways. This means preventing soil, grass clippings, chemicals and litter from washing into streets and gutters.
