Stormwater (Waterways)

Stormwater ​flows across the streets, driveways and rooftops from rain and snow melt and ends up in 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, car 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.

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. 

Arvada's Stormwater Permit

The City was issued a Permit from the State of Colorado that requires programs to be developed to protect area waterways. This Permit is called the Municipal Separate Storm Sewer System (MS4) Permit and includes programs such as public education, responding to spills, controlling construction pollutants, and keeping City facilities and activities protective of waterways. The Permit is tagged as an additional resource. 

Programs required under the State-issued Stormwater Permit are described in the City's Stormwater Management Plan, which recently changed its name to the Program Description Document (PDD).

Note:

Beginning January 1, 2019, request an electronic copy of the PDD by calling 720-898-7640 or by sending an e-mail to stormwater@arvada.org.
