(a) Technical Services of the Department. The department may, insofar as it is reasonably possible, make available the engineering and other technical services of the department, with or without charge, to any municipality, whether acting alone or with any other municipality or with the state, or person desiring them, in connection with the planning, acquisition, construction, improvement, maintenance or operation of airports, air navigation facilities, avigation easements or the acquisition, lighting, marking, or elimination of airport hazards.

(b) State Financial Assistance. The department may render financial assistance by grant or loan or both to any municipality or municipalities acting jointly, whether acting alone or with any other municipality or with the state, in the planning, acquisition, construction, improvement, maintenance, or operation of an airport owned or controlled, or to be owned or controlled by such municipality or municipalities, out of appropriations made by the general assembly for such purposes. This financial assistance may be furnished in connection with federal or other financial aid for the same purposes.

(c) Federal Aid; Other Available Funds; Technical Design Coordination with Department.

(1) The department may act as agent for any individual municipality or municipalities acting jointly, in accepting, receiving, receipting for and disbursing federal moneys, and other moneys, public or private, made available to finance, in whole or in part, the planning, acquisition, construction, improvement, maintenance, equipment or operation of a municipal airport, air navigation facility, avigation easement, or the acquisition, elimination, obstruction marking or obstruction lighting of airport hazards, and if requested by an individual municipality or municipalities acting jointly, may act as its or their agent in contracting for and supervising any planning, acquisition, construction, improvement, maintenance, equipment, operation, or elimination; and all municipalities are authorized to designate the department as their agent for the foregoing purposes. The department, as principal on behalf of the state, and any municipality on its own behalf, may enter into any contracts, with each other or with the United States or with any person, that may be required in connection with a grant or loan of federal moneys for municipal airport, air navigation facility, avigation easement, or airport hazard purposes. All federal moneys accepted under this section shall then be transferred or expended by the department upon the terms and conditions prescribed by the United States. All moneys received by the department pursuant to this section shall be deposited in the state treasury, and, unless otherwise prescribed by the authority from which the moneys are received, shall be kept in separate funds designated according to the purposes for which the moneys were made available, subject to disbursement by order of the department for such purposes.

(2) Any proposed construction activity that would involve any source of funding other than the department shall be subject to technical design coordination with the department and the receipt of its approval to ensure consistency with the state's airport system plan, unless such proposal would involve facilities for the use of the airlines or the military.
