Stormwater is water that flows across the land and into Arvada's streams, lakes, ditches and canals. When it rains or snows, debris, sediment, bacteria and nutrients on sidewalks, streets and parking lots wash into gutters, through storm drains, and eventually flow, untreated, into the creeks.

Other sources of water include over-irrigation, automobile wash water, or any other activity that results in water flowing into the gutters. Fertilizers, paint, oil, and other materials that can be harmful to the environment may end up in Arvada's lakes and streams after a storm event.

Ralston Creek, Van Bibber Creek, Leyden Creek, Little Dry Creek and the many small ponds and lakes within the City's boundaries may be potentially affected. There are also three major canals that flow through Arvada, specifically Church Ditch, Farmers Highline, and Croke Canal.

Arvada's Stormwater Permit

Permit related programs required under the State-issued Stormwater Permit are described in the City's Stormwater Management Plan.
