Sec. 43.136.  AUTHORITY OF SPECIAL-LAW MUNICIPALITY TO ANNEX FOR LIMITED PURPOSES ALONG NAVIGABLE STREAM.  (a)  The governing body of a special-law municipality located along or on a navigable stream may extend the boundaries of the municipality to include the area designated by Subsection (b) only to:
(1)  improve navigation on the stream by the United States, the municipality, or a navigation or other improvement district; and
(2)  establish and maintain wharves, docks, railway terminals, side tracks, warehouses, or other facilities or aids relating to navigation or wharves.
(b)  The municipality by ordinance may extend the boundaries to include an area composed of the navigable stream and the land on each side of the stream.  The area may not exceed 2,500 feet in width on either side of the stream as measured from the thread of the stream and may not exceed 20 miles in length as measured in a direct line from the ordinary municipal boundaries, either above or below the boundaries, or both.  Consequently, the area subject to the boundary extension is a strip 5,000 feet wide and 20 miles in length, or as much of that strip as the governing body considers advisable to add to the municipality.  The boundaries are extended on the adoption of the ordinance.
(c)  The governing body may acquire land in the added area by purchase, condemnation, or gift.  If condemnation is used, the municipality shall follow the condemnation procedure applying to the condemnation of land by the municipality for the purchase of streets.
(d)  This section does not authorize the municipality to extend its boundaries to include area that is part of or belongs to another municipality.
(e)  A municipality may not tax the property over which the boundaries are extended under this section unless the property is within the general municipal boundaries.
(f)  After the adoption of the ordinance extending the municipal boundaries, the municipality may fully regulate navigation, wharfage, including wharfage rates, and all facilities, conveniences, and aids to navigation or wharfage.  The municipality may adopt ordinances, including those imposing criminal penalties, and may otherwise police navigation on the stream and the use of the wharves or other facilities and aids to navigation or wharfage.
(g)  The municipality may designate all or part of the added area as an industrial district, as the term is customarily used, and may treat the designated area in a manner considered by the governing body to be in the best interest of the municipality.  The governing body may make written contracts or agreements with the owners of land in the industrial district, to guarantee the continuation of the limited purpose annexation status of the district and its immunity from general purpose annexation for a period not to exceed 10 years.  The contract or agreement may contain other terms considered appropriate by the parties.  The governing body and landowners may renew or extend the contract for successive periods not to exceed 10 years each.
(h)  Notwithstanding any other law, including a municipal ordinance or charter provision, the governing body by ordinance may change the status of an area previously annexed for general purposes to limited purpose annexation status governed by this section if:
(1)  the area previously annexed at any time was eligible to be included within the municipal boundaries under Subsection (b);
(2)  the owners of the area petition the governing body for the change in status;  and
(3)  the governing body includes the area in an industrial district designated as provided by Subsection (g) or any other law.
