A. The area of operation of a regional or consolidated housing authority shall be decreased from time to time to exclude one or more parishes or municipalities if the governing body of each of the parishes or municipalities in the area and the commissioners of the regional or consolidated housing authority each adopt a resolution declaring that there is a need for excluding the parish or municipality from the area.
B. If this action decreases the area of operation of the regional or consolidated housing authority to only one parish or municipality, regardless of its population, the authority shall thereupon become a housing authority for that parish or municipality. Such an authority has the same powers, duties and functions of a regular parish or municipal authority and is subject to all the provisions of this Part applicable thereto.
