Stormwater is rain that runs off hard surfaces such as rooftops, paved streets, and parking lots. As water runs off these surfaces, it can pick up pollution such as oils and dirt. Untreated stormwater might flow directly into a local stream, river or lake negatively impacting the habitat or wildlife.

Development codes and design manuals ensure compliance with the county's National Pollutant Discharge Elimination System (NPDES) Phase I Municipal Stormwater permit.
