Welcome!

Since 2008, the 5-2-1 Drainage Authority has provided stormwater management services and is responsible for NPDES compliance in the areas it serves within Mesa County.  The 5-2-1 DA complies with NPDES and other environmental regulations and informs the public about stormwater quality and projects.  

Stormwater Management

A major purpose of the 5-2-1 DA is to address the multi-jurisdictional problems of stormwater management.  Runoff from public lands such as the Colorado National Monument might cross private and public properties in the County, the City, under a state highway, and back into the County before entering the Colorado River at a point that happens to be in the City.
