RC Rural-Conservation Districts are designed to encourage the preservation of sizable stream valley, wooded areas and areas of steep slopes within the Township, for protection of the Exception Value Waters Valley Creek Watershed, the limestone/carbonate geology of the Great Valley, scenic and historic areas in proximity to Valley Forge National Historic Park and other open space and historic purposes. Accordingly, the district regulations contain a density standard which, among other things, provides for agricultural and low-density residential uses and facilitates the conservation and proper utilization of groundwater supplies and the control of soil erosion and surface water runoff and flooding.
