Summary

g. Boathouses, piers or permanent docks are not allowed in the Recreational or Scenic River District.

Docks that exceed eight feet in width require a shoreland building permit and may require a dock permit from the DNR.
Full Breakdown
02(4)). Any dock exceeding eight feet in width triggers a shoreland building permit application to the county Zoning Administrator before construction, and depending on the water body, the DNR may require its own public waters work permit on top of the county approval. The ordinance treats docks differently by river classification: on the Cannon River's Recreational and Scenic River Districts, boathouses, piers and permanent docks are prohibited entirely, and even a temporary dock or other waterfront use in the Scenic River District cannot go in without a conditional use permit approved by the Planning Commission and County Board.
01(A) separately requires a permit for construction of any structure regardless of cost or size, which the county applies to dock-adjacent work such as stairs and landings on the same lot. 02.
Violations & Fines
Installing or expanding a dock without the required shoreland or DNR permit is a violation of Ordinance No. 50. The county may first issue a warning notice or a formal notice of violation under Sections 9.01-9.02, but continued noncompliance escalates to a citation: Section 9.03 makes failure to comply a misdemeanor, punishable as provided by law, with each day the violation continues counted as a separate offense.
