Eden Prairie, MN Environmental Rules: Erosion Control (2026)

Section 11.55, Subd. 5.E requires Erosion Control Systems to be installed prior to commencement of any Land Alteration activity and maintained throughout the work. Stormwater passing through the site from adjacent areas must be diverted around disturbed areas where practical, and all site activity must be conducted to minimize the area of bare soil exposed at any one time. All disturbed earth must be stabilized by seeding, sodding, mulching or another City-approved control measure within fourteen days of ceasing construction or land alteration, unless a federal, state or local permit requires otherwise; seeding after September 15 is not an acceptable stabilization method under that fourteen-day clock.

Sites disturbing more than ten acres at once must build a temporary or permanent detention or retention basin with a surface area equal to at least 1% of the draining area and at least three feet deep, while smaller sites under ten acres use silt fences or equivalent measures along side and downslope edges (Subd. 5.E.3.b-c). During construction, the Permittee must inspect every erosion control system biweekly and within 48 hours of any rainfall of a half-inch or more, correcting any breach within 48 hours of discovery (Subd.

7.E). Erosion control systems must stay functional until final stabilization and be removed within thirty days after (Subd. 5.F-G). If the City finds a violation, Subd. 7.J declares each violation a public health and safety hazard and a public nuisance, allows the City to withhold building inspections until corrected, and authorizes a stop-work order on the offending activity.
