For the purpose of this chapter, the Village of Delhi is hereby divided into the following nine classes of districts:

The boundaries of these districts are hereby established on a map entitled "Zoning Map of the Village of Delhi," which map accompanies and is hereby declared to be 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 streets and alleys or such lines extended, the center lines of creeks and waterways or the corporate limit line as it existed at the time of the enactment of this chapter.

The zoning regulations and districts herein set forth and as outlined upon said Zoning Map are made in accordance with a Comprehensive Plan for the purpose of promoting the public health, safety, morals, convenience, order, prosperity and general welfare of the community. They have been designed to lessen congestion in the streets; to secure safety from fire, panic and other dangers; to provide adequate light and air; to prevent the overcrowding of land; to avoid undue concentration of population; and to facilitate the adequate provision of transportation, water, sewerage, schools, parks and other public requirements. They have been made with reasonable consideration, among other things, as to the character of each district and its suitability for particular uses, and with a view of conserving the value of buildings and encouraging the most appropriate use of land throughout the Village.

No building, structure or land shall hereafter be used and no building, structure or part thereof shall be erected, moved or altered unless for a use expressly permitted by and in conformity with the regulations herein specified for the district in which it is located, except as hereinafter provided.
