§ 119-oo. Expenses. The board of supervisors of a county, the town board of a town, the common council of a city, and the board of trustees of a village, or the governing bodies of the participating municipalities comprising membership in a regional planning council or county planning board or agency are hereby authorized independently or in collaboration with other local governments, in their discretion, to appropriate and raise by taxation money for the expenses of such regional planning council or county planning board or agency; and such municipal corporations shall not be chargeable with any expense incurred by such regional planning council or county planning board or agency except pursuant to such an appropriation. In the case of any regional planning council whose membership consists only of counties, each such county is authorized to provide for the payment of the moneys so appropriated for the expenses of such council to an officer of the council designated by the council to receive such moneys, provided that before any such moneys shall be paid to such officer, such officer shall have executed an official undertaking conditioned for the faithful performance of his duties in the manner provided in § 403 of the county law and provided that such undertaking shall have been approved by the governing body of each county involved.
