The Board of Trustees find that the lack of uniformity, dissimilarity, inappropriateness or poor quality of design and location of buildings and appurtenant structures, including facades, exterior lighting and signs, adversely affect the desirability of the immediate and neighboring areas and, thereby, impair the benefits of occupancy of existing property and the stability and value of both improved and unimproved real property in such areas, prevents the most appropriate development of such areas and destroys the proper relationship between the taxable value of real property in such areas and the cost of municipal services provided therefor. It is the intent of this article to establish procedures and design criteria necessary to avoid such results and to preserve and enhance the character, historical interest, beauty and general welfare of the Village and to ensure that the location and design of buildings, signs, other structures and open spaces in the Village shall aid in creating a balanced and harmonious composition of the whole as well as in the relationship of its several parts.
