N.J. Stat. § 18A:54-31
Whenever a board of education of a county vocational school district shall decide that it is necessary to sell bonds to raise money for any capital project, as defined in section 18A:21-1 of this Title, it shall prepare and deliver to each member of the board of school estimate a statement of the amount of money estimated to be necessary for such purpose or purposes.
The board of school estimate shall fix and determine the necessary amount and shall make two certificates thereof, one of which certificates shall be delivered to the board of education and the other to the board of chosen freeholders of the county in which the school district is situate.
The board of chosen freeholders, or the members of a county improvement authority at the request of the board of education pursuant to section 1 of P.L. 2015, c. 68(C.18A:7G-5a), may appropriate such amount and borrow such amount for the purpose or purposes aforesaid, and secure the repayment of the sum so borrowed, together with interest thereon, by the issuance of bonds or notes of the county pursuant to the local bond law, notwithstanding any debt limitation or requirement for down payment therein provided for, or by the issuance of bonds or notes of the county improvement authority pursuant to the "county improvement authorities law," P.L. 1960, c.183 (C.40:37A-44 et seq.). The proceeds of the sale of such obligations shall be paid to the treasurer of the county vocational school district, or in the case of bonds or notes issued by the county improvement authority to the chief financial officer of the authority if so directed by the treasurer, and shall be paid out only on the warrants or orders of the board of education of the school district, or in the case of bonds or notes issued by the county improvement authority on the orders of the chief financial officer of the authority. The treasurer of the board of education or the chief financial officer of the authority, as applicable, shall in no event disburse such proceeds, except to pay the expenses of issuing and selling such obligations and for the purpose or purposes for which such obligations were issued. If for any reason any part of such proceeds are not applied to or necessary for such purpose or purposes, the board of education of the county vocational school district may transfer the balance remaining unapplied to the general fund of the school district.
