This Local Law shall be known as the Zoning Ordinance of the Town of Amherst, County of Erie, State of New York.
1-2-1. 
The purpose of this Zoning Ordinance and the intent of the legislative authority in its adoption is to promote the environment of the town and its public health, safety, convenience, comfort, prosperity and the general welfare by regulating the use of buildings, other structures and land for residences, open space, public facilities, business, services, industry or other purposes; by regulating and restricting the bulk, height, design, building coverage and location of structures; by regulating and limiting population density; and, for the aforesaid purposes, to divide the land within the limits of the town into districts of such number and dimensions generally consistent with the policies of the Comprehensive Plan and to provide procedures for the administration and amendment of said Zoning Ordinance.
1-2-2. 
The ordinance is intended to achieve, among others, the following objectives:
A. 
To protect the character and values of residential, institutional and public uses, business, commercial and manufacturing uses and to insure their orderly and beneficial development;
B. 
To provide adequate open spaces for light, air and outdoor uses to include public, common and private open space areas;

H. 
To assure that structure and land use arrangements are aesthetically harmonious with nearby areas and structures;
I. 
To regulate the location of buildings and intensity of uses in relation to streets according to plans so as to cause the least interference with and be damaged least by traffic movements and hence result in lessened street congestion and improved public safety;

To guide the future development of the town so as to bring about the gradual conformity of land, structures and uses generally consistent with the policies of the Comprehensive Plan;

To accomplish the specific intents and goals set forth in the introduction to the respective sections; and
