Two or more municipalities, by vote of the city council in a city with the approval of the mayor or by vote of a town meeting in a town, may agree to establish, maintain and operate an airport as a joint enterprise, in this section referred to as a joint airport. For the purposes of this section, the foregoing authorization, in so far as it relates to the establishment of a joint airport, shall be deemed also to authorize the acquisition, construction, enlargement and improvement thereof, including other action involving capital expenditures in connection with such an airport, all of which action shall be comprehended within the meaning of the words "establish", "establishing" and "establishment", and such authorization, in so far as it relates to the maintenance and operation of such an airport, shall be deemed also to authorize the regulation, protection, policing, alteration or repair thereof, including other action involving expenditures, other than capital expenditures, in connection with such an airport, all of which action shall be comprehended within the meaning of the words "maintain and operate", "maintaining and operating" and "maintenance and operation". Within thirty days after such votes have been passed the mayor and city council of cities and selectmen of towns which have so voted shall meet and draft a tentative agreement covering the contemplated action or actions. Said tentative agreement when completed shall be submitted and may be resubmitted to the director of accounts in the department of corporations and taxation for approval as to its financial provisions and to the commission for approval as to its other provisions. The agreement, as approved by the commission and said director, shall become effective when agreed to by the mayor and city council of each such city and the town meeting of each such town. Any reference in this section to the mayor of a city shall, in case of a city having a Plan E form of government, be deemed to refer to its city manager.
In addition to the provisions covering the requirements contained in this section, such an agreement shall include, but shall not be limited to, provision for the following:
The joint airport commission from time to time shall determine the amounts necessary to be raised to establish the joint airport and shall apportion the balance needed, over and above the amount available for such purposes in the joint airport fund, among the several participating municipalities on the basis set forth in the agreement and shall promptly thereafter notify said municipalities of such apportionment by sending notice to the mayor, in the case of a city, and to the selectmen, in the case of a town. There shall be no referendum to the voters on any action taken under this paragraph by the legislative body of any participating municipality. In case any such municipality fails to pay over to the treasurer of the joint enterprise the amount of its apportionment within the time specified in the agreement for such payment, the treasurer of such municipality shall forthwith certify such amount to the board of assessors of his municipality who shall include such amount in the tax levy next following the certification, and the amount when raised shall be paid over by the treasurer of such municipality to the treasurer of the joint enterprise.
The joint airport commission shall determine the amounts necessary to be raised to maintain and operate the joint airport and shall apportion the balance needed, over and above the amount available for such purposes in the joint airport fund, among the several participating municipalities on the basis set forth in the agreement and shall promptly thereafter notify the treasurers of said municipalities of such apportionment. Every treasurer so notified shall, annually in December, certify the amount of such apportionment to the board of assessors of his municipality, who shall, unless funds are available from appropriations or otherwise, include such amount in the tax levy of the following year, and the amount of such apportionment shall be paid over by the treasurer of such municipality to the treasurer of the joint enterprise within the time specified in the agreement for such payment.
Action by a participating municipality in establishing, maintaining, and operating a joint airport shall be authorized to the same extent and subject to the same provisions of law as in the case of like action by such municipality independently with respect to an airport, except as otherwise provided in this section and except that the joint airport commission is authorized to acquire property by eminent domain, purchase or otherwise for purposes of the joint airport in the names of the participating municipalities but only within the territorial limits of such municipalities, and each of such municipalities shall have the same interest in the property so acquired that it has in the joint airport under the agreement.
