STATEMAP is a competitive, matching-funds grant program between the state geological surveys and the United States Geological Survey for conducting basic geologic mapping. STATEMAP is one of three components of the National Cooperative Geologic Mapping Program (NCGMP). A broad-based stakeholder group comprises the Colorado Geologic Mapping Advisory Committee (GMAC) that prioritizes the areas for mapping. The GMAC has ranked priorities for geologic mapping in Colorado.  Each year the state geological surveys submit proposals to a national review panel for monetary awards up to $300,000. Each grant requires a 50/50, hard-money match. Colorado has historically been in the top five grant awards in the nation.

STATEMAP over the past fifteen years has helped support detailed mapping of bedrock and surficial deposits in seventeen counties (Chaffee, Clear Creek, Costilla, Delta, Douglas, Eagle, El Paso, Garfield, Lake, La Plata, Mesa, Moffat, Montrose, Park, Pitkin, Routt, and Summit). This new geologic map information is regularly incorporated into decision-making on a wide variety of local and countywide issues that include:

  • protecting ground water;
  • locating new municipal wells;
  • siting waste-disposal facilities;
  • identifying potential mineral resources;
  • protecting home-owners from geologic hazards; and
  • addressing a broad spectrum of land-use concerns.

The results of Colorado’s STATEMAP program are used by planners and decision makers at the state, county, and municipal levels of government. Colorado STATEMAP quadrangles have been used as the scientific basis for preparing:

  • a resource map of sand and gravel for Garfield County;
  • a geologic hazard map for Clear Creek County;
  • a post-wildfire debris flow map in La Plata County;
  • a geologic hazard map for Montrose County;
  • a landslide susceptibility map for the city of Colorado Springs, which has suffered losses of $75 million from landslides;
  • a Denver Basin aquifer map, and
  • a detailed map of a proposed state park near Cheyenne Mountain.
