Bloomington FAQ
Do small home additions need erosion control?
Smaller projects under one acre still need basic silt fence and inlet protection if the city or watershed district requires it.
What happens if sediment reaches a creek?
The watershed district can issue cease-and-desist orders and MPCA may pursue penalties for unpermitted discharges to public waters.
Minneapolis FAQ

Formal plans are required over 10,000 sq ft, but silt fencing is good practice for any excavation and is often required by the issuing inspector regardless of size near storm drains.
What counts as shoreland in Minneapolis?
Land within 200 feet of Mississippi River, Minnehaha Creek, Bassett Creek, Lake of the Isles, Lake Harriet, and other protected waters falls under the Shoreland Overlay with stricter erosion rules.
