This bill implements a prohibition on the placement or use of a nonwater-dependent floating structure in, on or over inland waters or coastal waters. As defined in the bill, a "nonwater-dependent floating structure" is a waterborne structure that is supported wholly or partially by the structure's own buoyancy and that supports a nonwater-dependent use. "Nonwater-dependent uses" is defined as those uses that can function in a location other than the surface waters of the State and that do not require, for their primary purpose, location on submerged lands or direct access to inland waters or coastal waters. The prohibition includes exceptions for functionally water-dependent uses, swimming structures, water toys, ice fishing shacks and aquaculture facilities. The bill also clarifies the regulation of houseboats and homemade watercraft under the laws regulating watercraft.
