The Village of Tivoli is hereby divided into the following districts:

The boundaries of the districts listed in § 231-5 are hereby established on a map entitled "Zoning Map of the Village of Tivoli," which map accompanies and is hereby declared to be a part of this chapter.[1]

Where a district boundary line, as appearing on the Zoning Map, divides a lot or land in single ownership as existing at the time of this enactment, the use authorized on and the district requirements applying to the less restricted portion of the property shall be construed as extending into the remaining portion of the property beyond the district boundary lines for a distance not exceeding 35 feet. Otherwise, unless shown to the contrary on the Zoning Map, the boundary lines of districts are the center lines of the streets and alleys, or such lines extended, railroad right-of-way lines, the center lines of creeks and waterways and the corporate limits line as it existed at the time of the enactment of this chapter. Notwithstanding any of the foregoing, the boundary of the LC Districts shall be measured horizontally from the middle of Stony Creek or horizontally from the high-water mark of the Hudson River.
