63-82. Procedure for inclusion of additional units of local government; notice and hearing; actions to set aside proceedings.

(a) If, at any time subsequent to the creation of a special airport district, there shall be filed with the district board a resolution of the governing body of a unit of local government requesting inclusion in the district of such unit of local government, and if the district board shall favor the inclusion in the district of such unit of local government, the district board shall notify the governing body of each of the participating units of local government within which the district lies and shall propose to such governing bodies an appropriate amendment of the concurrent resolutions creating the special airport district.

(b) The procedures set forth in G.S. 63-79 regarding the creation of a special airport district shall apply to the inclusion in such special airport district of additional units of local government.

(c) If all of the participating units of local government agree to the amendment of the concurrent resolutions creating the special airport district to include such unit of local government in the special airport district, the presiding officer of the governing body of each of such participating units of local government, including the unit proposed to be included, shall cause to be published in the manner provided in G.S. 63-79, a notice of the inclusion of such unit of local government.

(d) Any action or proceeding in any court to set aside such amendatory resolutions providing for the inclusion of a unit of local government within a special airport district or to obtain any other relief upon the ground that such amendatory resolutions or any proceeding or action taken with respect to the inclusion of the unit of local government within the district is invalid, must be commenced within 30 days after publication of the notice. After the expiration of such period of limitation, no right of action or defense founded upon the invalidity of the amendatory resolutions or the inclusion of the unit of local government in the district shall be asserted, nor shall the validity of the amendatory resolutions or the inclusion of the unit of local government in the district be open to question in any court upon any ground whatever, except in an action or proceeding commenced within such period. Provided that no such action or proceeding to set aside such amendatory resolutions shall impair or otherwise affect the conclusivity of the concurrent resolutions as provided in G.S. 63-80.

(e) Immediately following the inclusion of any additional unit of local government within an existing district, members representing such additional unit of local government shall be appointed to the district board in the manner provided in G.S. 63-81 hereof.

(f) The annexation by a participating unit of local government of an area lying outside the district shall not be construed as the inclusion within the district of an additional unit of local government within the meaning of the provisions of this section; but any such area so annexed shall become a part of the district and shall be subject to all debts and supplemental tax obligations thereof.
