Court Upholds Maine’s Stormwater Protections

FRIENDS OF CASCO BAY • September 16, 2026

Maine’s Superior Court has upheld key provisions in a federal stormwater permit that applies to the state’s most urban areas. The court’s action upholds a requirement that regulated municipalities must adopt low impact development ordinances. This is good news for Casco Bay and many other waters in the state because stormwater is one of the largest sources of pollution into our waters.
