Hennepin County requires stormwater management practices on construction and redevelopment sites to protect lakes, rivers, and the Mississippi River watershed under county and watershed district rules.
Projects disturbing one or more acres in Hennepin County must obtain MPCA NPDES coverage and follow the local watershed management organization rules. The county's Stormwater Pollution Prevention Program (SWPPP) targets sediment, phosphorus, and chloride loading. Hennepin County operates a regulated MS4 permit covering county roads and facilities. Watershed districts such as Minnehaha Creek, Bassett Creek, and Nine Mile Creek impose volume control, infiltration, and rate-control standards. Site plans typically require treatment of the first inch of runoff and protection of wetland buffers near Lake Minnetonka and other county waters.
Unpermitted earthwork or untreated discharges may trigger stop-work orders, MPCA referral, and civil penalties enforced through the county and watershed district.
