Stormwater Management Program Objectives

Stormwater….what’s it all about?

The primary function of a storm sewer system, including the natural channels, is the collection, movement and storage of stormwater runoff.  In a watershed-based approach to urban stormwater management, the pipes, inlets, outlets and other stormwater system features assist in moving the stormwater from areas where it can impact the safety, health and welfare of the communities within these watersheds.  Inadequate stormwater management can result in flooding, infrastructure and property damage, excessive soil erosion, degraded open space, unacceptable water quality in potable water supply reservoirs and other water bodies with decreased recreational and/or fish and wildlife values.

Douglas County is committed to taking a proactive role in the management of its stormwater system as a part of providing quality services to its citizens.  One example of our proactive approach is the Storm Drainage Design and Technical Criteria Manual which provides guidance to developers and the County for effective management of stormwater and stormwater systems.

Public Education and Outreach

In a cooperative effort with other government entities providing stormwater programs within Douglas County, a Co-op was established to combine resources and coordinate outreach and education efforts throughout the County.  Through these efforts, “One Thing Is Clear…our creeks, rivers and lakes depend on you” public awareness project was created.  Through this branding a variety of positive stormwater awareness messages are provided throughout the County.  For more information visit www.onethingisclear.org

In addition to this local outreach effort the County’s Stormwater Management Program also provides links to a variety of agencies and resources on our links page.

Why is the stream not the right color?

There could be a lot of reasons why the water flowing down the stream is not the color you think it should be…..perhaps there has been mud washing off of a construction site, or some kind of spill has occurred and reached the stream through the stormwater system.  Regardless, the Douglas County’s Stormwater Management Program wants to know about it.  To report incidents call theStormwater Hotline at 303.663.6181.

The County is responsible for management of sediment control on construction and development sites through our Grading, Erosion, and Sediment Control (GESC) program.

Douglas County staff is in charge of ensuring unpermitted discharges are eliminated, cleaned up properly, and reported to the State Water Quality Control Division
