(A) All land disturbance activities on property with wetlands must follow § 155.341 of the City of St. Michael Zoning Ordinance (Wetland System District).
(B) Runoff must not be discharged directly into wetlands without appropriate quality and quantity runoff control, depending on the individual wetland’s vegetation. See the current version of the Minnesota Pollution Control Agency’s publication, Storm-Water and Wetlands: Planning and Evaluation Guidelines for Addressing Potential Impacts of Urban Storm-Water and Snow-Melt Runoff on Wetlands for guidance.
Commentary:
The sensitivity of a wetland to degradation varies with vegetation type. Sedge meadows, open bogs and swamps, coniferous bogs, calcareous fens, low prairies, lowland hardwood swamps, and seasonally flooded basins are highly sensitive to degradation, while flood plain forests, reed canary grass meadows, shallow reed canary grass, cattail, giant reed or purple loosestrife) marshes are only slightly sensitive to degradation.
