N.Y. Pub. Auth. Law § 3659
The county is authorized to pledge to and agree with the holders of any issue of bonds issued by the authority pursuant to this title and secured by such a pledge that the county will not limit, alter or impair the rights hereby vested in the authority to fulfill the terms of any agreements made with such holders pursuant to this title, or in any way impair the rights and remedies of such holders or the security for such bonds until such bonds, together with the interest thereon and all costs and expenses in connection with any action or proceeding by or on behalf of such holders, are fully paid and discharged. Nothing contained in this title shall be deemed to restrict any right of the county to amend, modify or otherwise alter local laws, ordinances or resolutions imposing or relating to the taxes imposed pursuant to the authority of article twenty-nine of the tax law or other taxes or fees or appropriations related to any such taxes or fees, so long as, after giving effect to such amendment, modification or other alteration, the amount of tax revenues projected by the authority to be available during each of its fiscal years following the effective date of such amendment, modification or other alteration shall be not less than two hundred percent of maximum annual debt service on authority bonds then outstanding. Subject to the foregoing sentence, the authority shall not include in any resolution, contract or agreement with the holders of its bonds any provision which provides that a default occurs as a result of the county exercising its right to amend, modify, or otherwise alter such taxes imposed pursuant to the authority of article twenty-nine of the tax law or other taxes or fees. Nothing in this title shall be deemed to obligate the county to make additional payments or impose taxes other than those imposed pursuant to the authority of paragraph one of subdivision (a) of section twelve hundred ten of the tax law to satisfy the debt service obligations of the authority.
