Water quality protection along county roads
Hennepin County manages 2,200 lane miles of roadway and right-of-way throughout the county. Included in this is the proper treatment and discharge of stormwater. This is governed by the Municipal Storm Sewer System permitting by the Minnesota Pollution Control Agency.
The county inspects drainage infrastructures annually to ensure both proper drainage and that structures are properly filtering for water quality protection purposes. Road upgrades and maintenance include studying water quality for the best management practice and upgrading infrastructure when necessary.
