Natural Environmental Constraints Cedar Grove contains the following natural environmental constraints to development activity: floodplains, water supply watersheds, steep slopes and poor soil conditions. FLOODPLATINS. The major flooding hazard in Cedar Grove Township exists along the Eno River, the South Fork of the Little River and Forest Creek. The areas that would be subject to flooding in a storm which would occur on an average once every 100 years is not extensive. It is generally confined to a band along these streams rarely exceeding 1000 feet. WATER SUPPLY WATERSHED. The Eno River, which has its headwaters in Cedar Grove Township, is the source of the water supply for the Town of Hills- borough and for the Orange-Alamance Water Systems Incorporated, a non- profit association which supplies:water along the U.S. 70 corridor west of Hillsborough including the Efland community and areas in Alamance County around the Town of Mebane. These two water supplies draw water directly from the Eno, Lake Orange, a water supply reservoir, is sited on the east branch of the Eno River in Cedar Grove Township. The County owns the water rights from this impoundment. Lake Orange is a secondary reservoir from which water can be released during dry spells to increase the flow in the Eno for the two downstream users. The watershed area in Cedar Grove Township should be protected from types and intensities of development which could reduce the water quality in the Eno River. STEEP SLOPES. Cedar Grove Township is in the headwaters of three major drainage basins, the Neuse Basin, the Roanoke Basin and the Cape Fear Basin. As a result streams are quite small in Cedar Grove Township and do not have the power to cut steep valleys. As a result, there are very few areas with slopes greater than 15% in the Township. SOILS. Soils of the Applingr-Helena association predominate in northern and western Cedar Grove Township. They consist of well drained and mode- rately well drained soils that have a surface layer of sandy loam and a subsoil of clay or sandy clay. This soil type is nearly ideal for grow- ing tobacco and accounts for the concentration of tobacco farming activi- ty in the Township. The clay subsoils of the Appling-Helena association, however, makes this same area poor for many other land uses, especially on-site waste disposal systems. In the southern and eastern portions of Cedar Grove Township deep, well drained soils of the Georgpville-Herndon soil association predominate. They are some of the better soils to be found in Orange County and are well suited for most urban uses. PLANNING FRAMEWORK AND APPLICATION Or z Conceits The following Township policy statPmPnts represent the organizing concepts around which the Land Use Plan for Cedar Grove Township is constructed: 1) Cedar Grove Township should retain its agricultural and, low density residential character. 2) The integrity and character of the small crossroads corammitip
