(c) (Adoption of Airport Zoning Regulations. )

(1) For the purposes and reasons mentioned in Sub-section
16(b) of this sub-title, every political subdivision may adopt,

airport zoning regulations for any airport within its cor-
porate limits, or outside its corporate limits to the extent, in
the manner and under the conditions provided in subpara-

of such general zoning regulations, and be administered and
enforced in connection therewith, but such general zoning
regulations shall not limit the effectiveness or scope of the
regulations adopted under this sub-title.

(3) Any two or more political subdivisions may agree, by
appropriate action of the governing bodies of such political
subdivisions, to create a joint board and delegate to said
board the powers herein conferred to adopt, revise, administer
and enforce airport zoning regulations to protect the aerial
