In order to carry out the purpose, intent and objectives of this chapter, the Town is hereby divided into the following districts, which shall be designated on the Official Zoning Map by symbols and boundaries, said districts to be known as:

Provision for Official Zoning Map. The aforesaid districts are designated by symbols and the location and boundaries of said districts are shown on the Official Zoning Map, which, together with all explanatory matter thereon, is hereby adopted by reference and declared to be part of this chapter.[2] If, in accordance with the provisions of this chapter, changes are made in district boundaries or other matters portrayed on the Official Zoning Map, such changes shall be entered on the Official Zoning Map after the amendment has been adopted by the Town Board.

No building, structure or land shall hereafter be used or occupied, and no building, structure or part thereof shall hereafter be erected, constructed, reconstructed, moved or structurally altered, except as permitted in the district in conformity with all of the regulations herein specified.

No building or other structure shall hereafter be erected, moved or altered which exceeds the height or bulk requirements, fails to meet minimum square footage requirements, accommodates or houses a greater number of families, occupies a greater part of the lot area or has smaller side, rear or front yards or other open spaces than herein permitted or required.

No part of a yard or other open space or off-street parking, loading or stacking space required about or in connection with any structure for the purpose of complying with this chapter shall be included as part of a yard, open space or off-street parking, loading or stacking space required for any other structure.

No yard or lot existing at the time of passage of this chapter shall be reduced in dimension or area below the minimum requirements set forth herein. Yards or lots created after the effective date of this chapter shall meet at least the minimum requirements established by this chapter.

No required yard shall be alienated from that portion of the lot on which a structure is located.

Boundaries indicated as approximately following the center lines of streets or highways shall be construed to follow such center lines.

Boundaries indicated as approximately following existing lot lines shall be construed as following such lot lines.

Boundaries indicated as approximately following Town boundaries shall be construed as following such boundaries.

Boundaries indicated as following railroad lines shall be construed to be midway between main tracks.

Boundaries indicated as approximately following the edge of streams, rivers, canals, lakes or other bodies of water shall be construed as following the center lines thereof.

Boundaries indicated as parallel to or extensions of features indicated in Subsections A through E above shall be construed pursuant to those provisions.

Where physical or cultural features existing on the ground are at variance with those shown on the Official Zoning Map or in other circumstances not covered above, the Board of Appeals shall interpret the district boundaries.

Where district boundary lines established upon the adoption of this chapter divide a lot which was in single ownership at that time, the Board of Appeals may permit the extension of the regulations of the lower use district into the other district if it finds, after receiving a recommendation from the Planning Board, that such an extension and the resulting use are consistent with the intent of this chapter and the objectives of the Comprehensive Plan.
