Iowa Code Title XI. Natural Resources [Chs. 455-485] § 462A.17. Local regulations restricted

1. This chapter and other applicable laws of this state govern the operation, equipment, numbering and all other matters relating thereto of any vessel whenever the vessel is operated or maintained on the waters of this state under the jurisdiction of the commission, but this chapter does not prevent the adoption of any ordinance or local law relating to the operation or equipment of vessels. Such ordinances or local law are operative only so long as they are not inconsistent with this chapter or the rules adopted by the commission.

2. Any subdivision of this state may, but only after public notice thereof by publication in a newspaper having a general circulation in such subdivision, make formal application to the commission for special rules and regulations concerning the operation of vessels on any waters within its territorial limits and shall set forth therein the reasons which make such special rules or regulations necessary or appropriate.

3. The commission, upon application of local authorities, may make special rules in conformity with this chapter, concerning the operation of vessels on any waters of this state under the jurisdiction of the commission within the territorial limits of any subdivision of this state. Special rules shall only be adopted upon a finding by the commission that the rules are necessary to carry out the policies and purposes of this chapter due to special conditions with regard to a particular body of water and that the special rules provide greater protection to the public health, safety, and welfare than the rules of general application.
