These regulations, restrictions and boundaries may, from time to time, be amended, supplemented, changed, modified or repealed by the Board of Trustees of the Village of Hammondsport.

In case, however, of a protest against such change signed by the owners of 20% or more of the area of the land included in such proposed change or by the owners of 20% or more of the land immediately adjacent extending 100 feet therefrom or by the owners of 20% or more of the land directly opposite thereto extending 100 feet from the street frontage of such opposite land, such amendment shall not become effective except by the favorable vote of 3/4 of the members of the Board of Trustees.

However, no such regulation, restriction or boundary shall become effective until after a public hearing in relation thereto, at which parties in interest and citizens shall have an opportunity to be heard.

A written notice of any proposed change or amendment affecting the property within the protectively zoned area of a housing project authorized under the Public Housing Law, as such area is shown on an approved zoning map filed with the village officer charged with enforcement of zoning regulations, shall be given to the housing authority erecting or owning the project and to the government providing financial aid or assistance thereto at least 10 days prior to the date of such public hearing. A written notice of any proposed change or amendment affecting property within 500 feet of the boundaries of any state park or parkway, town or county shall be given to the Clerk of the County Legislature or other person performing like duties, and in the case of any state park or parkway, to the Regional State Park Commission having jurisdiction over such state park or parkway, at least 10 days prior to the date of such public hearing. The town or county shall have the right to appear and to be heard at such public hearing with respect to any such proposed change or amendment, but shall not have the right of review by a court as hereinafter provided.

Every amendment of this chapter hereafter adopted shall be entered in the minutes of the Village Board, and a notice thereof, exclusive of any map incorporated therein, shall be published once in the official newspaper, and a copy of such chapter or amendment, together with a summary or abstract of any map incorporated therein, shall be posted conspicuously at or near the main entrance to the office of the Village Clerk, and affidavits of the publication and posting thereof and shall take effect upon filing with the Secretary of State.
