The Town Board may, from time to time, on its own motion or on petition or on recommendation from the Planning Board, amend the regulations and districts established under this chapter after public notice and hearing in each case. All petitions for any amendment of the regulation or districts herein established shall be filed, in writing, in a form required by the Town Board and shall be accompanied by a certified check in an amount set from time to time by resolution of the Town Board to help defray the cost of advertising the hearing of said petition and incidental disbursements.

Every proposed amendment, unless initiated by the Planning Board, shall be referred to the Planning Board. The Planning Board shall report its recommendations thereon to the Town Board, accompanied by a full statement of the reasons for such recommendations, prior to the public hearing. If the Planning Board fails to report within a period of 45 days from the date of receipt of notice or such longer time as may have been agreed upon by it and the Town Board, the Town Board may act without such report.

The Town Board, by resolution, shall fix the time and place of the public hearing and cause notice to be given as follows:

If a protest against the proposed amendment is presented to the Town Board, duly signed and acknowledged by the owners of 20% or more of the area of land included in such proposed amendment or by the owners of 20% or more of the area of the land immediately adjacent extending 500 feet therefrom, or by the owners of 20% or more of the area of land directly opposite thereto extending 500 feet from the street frontage of such opposite land, such amendment shall not be passed except by the favorable vote of at least four members of the Town Board.

The Planning Board, in accordance with Town Law § 278, may, simultaneously with the approval of a plat, make any reasonable change to the regulations established under this chapter with respect to the land so platted. Before the Planning Board shall make any such change, there shall be a public hearing preceded by the same notice as in the case of the approval of the plat itself. Upon the filing of the plat in the office of the County Clerk, such changes shall be and become part of the regulations of this chapter, shall take place of any regulations established herein by the Town Board, shall be enforced in the same manner and shall be similarly subject to amendment.
