RU
Rural District
RU Rural Districts are intended to facilitate agricultural, conservation, recreation and other open space purposes; to protect and preserve prime agricultural land and the continued viability of agricultural security areas; to recognize the relationship and continuity of development with viable agricultural operations; to protect and preserve natural and historic resources; and to promote and provide for a rational pattern of Township growth. Accordingly, the districts contain use and area regulations which provide for farming and very low density dwellings; discourage premature and scattered, isolated higher density development which is difficult to service adequately, yet make provision for higher density development under given conditions; facilitate the conservation of agricultural, creek valley and woodland areas; and facilitate the conservation and proper utilization of groundwater supplies and control of surface water flooding
