In addition to the other limitations of this chapter on the power to contract indebtedness:
The state comptroller in his discretion may require the submission of additional information in such form and detail as he shall deem sufficient, or may cause an investigation to be made, to aid him in making the determinations herein required. Any such application may be amended prior to any final determination. If the state comptroller shall determine (1) that the issuance of the obligations will not cause an undue burden upon the property of the district, and (2) that amount of the indebtedness of the town for all purposes as evidenced by bonds, bond anticipation notes, capital notes and budget notes, plus the amount of the indebtedness proposed to be incurred for the improvement district, less the amount of budgetary appropriations for the payment of any such indebtedness, whether or not such appropriations have been realized as cash, as of the date of the application filed with the state comptroller, will not exceed fifteen per centum of the average full valuation of the taxable real property of the town he shall grant such application; otherwise, it shall be denied. Such average full valuation shall be determined in the manner provided in this subdivision. If any such application shall be granted by the state comptroller, it shall not be necessary to apply to the state comptroller under the provisions of subdivision three of this section for his consent to the issuance of the obligations described in the application made pursuant to this subdivision. There shall be excluded from the amount of indebtedness to be considered by the state comptroller in making such determination any indebtedness allocated or apportioned or proposed by all the participating municipal corporations to be allocated or apportioned to any municipal corporation other than such town in accordance with the provisions of section 15.10 of the local finance law.
