This section applies only to code counties and municipalities. It is the policy of the State to authorize each code county and municipality to displace or limit competition in the area of port regulation to: provide for safe harbors free of congestion and navigational hazards; protect marine life and wildlife; and prevent water pollution and erosion. Notwithstanding any anticompetitive effect, a code county or municipality may: grant one or more franchises or enter into contracts for the placement or construction of structures in or on the waters of the county or municipality; issue licenses for wharves and piers; or issue permits for mooring piles, floating wharves, buoys, and anchors.
