Mississippi River Corridor Critical Area Rulemaking

Mississippi River

The Minnesota Department of Natural Resources (DNR) published rules for the Mississippi River Corridor Critical Area (MRCCA), an important milestone toward protecting the river's 72-mile stretch through the Twin Cities metropolitan area.

The rules are the result of extensive collaboration with local governments, business and environmental groups, and property owners to hear concerns, gather ideas, and balance interests for rules that:

  • improve protections for water quality, habitat and scenic views;
  • protect existing development and allow redevelopment while protecting key resources; and
  • provide clear standards for landowners and simplify local government administration.


The rules, district maps, Statement of Need and Reasonableness and other information are available on the MRCCA project website.
