Aggregate Resource Mapping

Program Information

The Aggregate Resource Mapping Program (ARMP) began in 1984 when the Minnesota Legislature passed a law (Minnesota Statutes, section 84.94) to:

  • Identify and classify aggregate resources out side of the Twin Cities metropolitan area,
  • Give aggregate resource information to local units of government and others for making comprehensive land-use and zoning plans,
  • Introduce aggregate resource protection, and
  • Promote orderly and environmentally sound development of the resource.

There is a need to plan for the future supply of aggregate before they are irretrievably lost.

Several factors can reduce the availability of aggregate resources . As a result, the delivered price of aggregate resources is increasing due to increasing transportation distances to the market.

Since roughly 50% of the total amount of aggregate produced is used for public roads and public works projects, it is in the tax payer's best interest to maintain a local supply of aggregate resources for current and future needs.

This site provides information about the distribution of quality aggregate resources for local units of government, citizens, land use planners, private companies, and environmental groups. Completed aggregate resource plates are available free of charge in several formats:
