Development of Regional Impact (DRI) Review Requirements

Protection Activity: Regulations and Permits

Development of regional impact (DRI) applies to any development that would have a substantial effect upon the health, safety, or welfare of citizens of more than one county because of its character, magnitude, or location. Local jurisdictions or regional planning commissions can use the DRI designation to assess the potential for water pollution or other adverse impacts to source water from the proposed projects in source water protection areas and recommend measures to reduce such impacts. DRI reviews can educate municipalities and developers about source water protection.
