Storm Water & Wetland Management

McIntyre Gulch, DFC, Denver, COUrban storm water runoff is one of the leading causes of pollution in rivers and lakes. In fields and forests, rain is absorbed by soil or taken up in tree or plant roots. In developed area, rainwater travels across paved areas and accumulates pollutants such as oil and grease, chemicals, nutrients, metals, and bacteria which are then carried to gutters, gullies and storm-sewer systems. Heavy precipitation or snow melt may cause sewer overflow which, in turn may lead to contamination of water sources with untreated human and industrial waste, toxic materials, and other debris.

This page offers links and procedures to ensure that:

  • Storm drains are protected from contamination and construction sediment
  • Awareness, training and education
  • Storm water best management practices.

Agency clients at the Denver Federal Center can count on the GSA to implement programs that remediate and abate storm water runoff. GSA implemented a construction site inspection program to reduce sediment discharge to storm water. GSA has also placed distinct markers near storm drains to increase public awareness of potential discharges to McIntyre Gulch and the Platte River. Master site plan for the DFC (PDF 893KB)
