Excavations to connect boat slips, canals, lagoons, and harbors to public waters require a public waters permit and must comply with Minnesota Rules, Chapter 6115. 8.4 Stormwater Management. 8.41 General Standards: A. When possible, existing natural drainageways, and vegetated soil surfaces must be used to convey, store, filter, and retain stormwater runoff before discharge to public waters. B. Development must be planned and conducted in a manner that will minimize the extent of disturbed areas, runoff velocities, erosion potential, and reduce and delay runoff volumes. Disturbed areas 8.34. DNR permits for public water excavations require that the local government have a DNR-approved shoreland zoning ordinance (Minnesota Statute, Section 103G.245, Subd. 8(1)) as a condition of a public water permit approval. The DNR may deny a permit for public waters excavations if there is no shoreland ordinance or if the current ordinance is not consistent with the ordinance the DNR has approved. 8.41. These are common stormwater management BMPs. If any of these specific provisions exist elsewhere in a local ordinance and are similar, they may be omitted here.
