Critical Area

A natural, cultural and historic wonder, the Mississippi River defines and shapes our metro area. Because of its importance, the 72-mile stretch through the Twin Cities is recognized as a national park unit and a state critical area. 

Along with those designations came some protections, but Friends of the Mississippi River (FMR) knew we could do better. Starting in 2007, FMR pushed alongside communities and policymakers for stronger, more protective riverfront rules for the Mississippi River Corridor Critical Area. 

By the end of 2025, all 25 river cities and townships in the Twin Cities metro had adopted clearer, science-based regulations for riverfront development through the Minnesota Department of Natural Resources' critical area program.
