The purpose and provisions of this chapter are those as set forth by Sections 603, 603.1, 604 and 605 of the Pennsylvania Municipalities Planning Code. The Board of Supervisors of the Township of Potter, County of Beaver and Commonwealth of Pennsylvania, does hereby ordain that these regulations are made in accordance with the Potter Township Comprehensive Plan and designed to lessen congestion in the streets, to secure safety from fire, panic, and other dangers, to promote health and the general welfare, 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. Such regulations shall be made with reasonable consideration, among other things, to the character of the district and its peculiar suitability for particular uses, and with a view to conserving the value of buildings and encouraging the most appropriate use of land throughout the Township. This chapter is exclusive zoning in that no use may be operated in a district unless it is specifically listed as a use by right for that district.
