N.Y. Alt. County Gov't Law § 56
A county which shall have adopted an alternative form of county government may, after the lapse of three years from the date such form becomes effective in the county, rescind its previous action and elect to be governed by the provisions of the county law as then or thereafter in force. No such question shall be submitted more often than once in every four years. All of the provisions of this chapter relating to initiating a proceeding for the adoption of an alternative form of county government and to the submission and approval of the question shall apply also to the abandonment of an existing alternative form of county government as authorized by this section. Any such question shall become effective, if approved, on the first day of January of the year specified in the petition or resolution, and if no year be specified, shall become effective on the first day of January of the second year after its adoption. The question shall be in substantially the following form: "Shall the county of (name of county) abandon its present form of county government and be governed by the county law after January first (year)?"
