Iowa Admin. Code r. 571-16.2
Permits are required for docks on all water bodies open to the public for boating or other recreational uses. This division governs permits for all types of docks except docks in dock management areas designated by the department. Classes of permits are designated as follows: Class I permits authorize standard private docks, other private docks in specified areas, and docks permitted by the U.S. Army Corps of Engineers; Class II permits authorize docks that are managed by governmental entities and extend from shoreline property owned by those governmental entities; Class III permits authorize nonstandard private docks; and Class IV permits authorize commercial docks. A dock that involves placement of fill or construction of a permanent structure in a state-owned public water body also requires a construction permit issued under 571-Chapter 13. A dock issued a permit by the U.S. Army Corps of Engineers, located on a water body managed by the U.S. Army Corps of Engineers, does not require a state dock permit under this chapter.
