The Village Board of Trustees hereby finds that excessive uniformity, dissimilarity, inappropriateness or poor quality of design in the exterior appearance of any buildings erected, altered, remodeled or extended in any neighborhood adversely affects the desirability of the immediate area and neighboring areas for residential and business purposes or other purposes and, by so doing, impairs the benefits of occupancy of existing property in such areas, impairs the stability and value of both improved and unimproved real property in such areas, prevents the most appropriate development and use of such areas, produces degeneration of property in such areas, with attendant deterioration of conditions affecting the health, safety and general welfare of the community, and impairs a proper relationship between the taxable value of real property in such areas and the cost of municipal services provided therefor. It is the purpose of this article to prevent these and other harmful effects of such exterior appearance of buildings and related exterior improvements erected or altered in any neighborhood so designated for architectural review and thus to promote the health, safety and general welfare of the community, conserve the value of the buildings and encourage the most appropriate use of land within the Village of Spencerport.
