SECTION 1.0 INTRODUCTION The purpose of this document is to present the watershed management plan that will help protect the water q~lity in the Coddle Creek Re~-voir (Reservoir). Cabarets County, (County) North Carolina h:~_~ contracted with HDR Engineering to analyze the land use and natural resource data on the Coddle Creek watershed. The goal of the project is to develop a strategy to manage watershed lands to protect and maintain the water cp~ality in the Reservoir, a ma~n source of drinking water for the County. Purs~ant to regulations promulgated by the United States Environmental Protection Agency (EPA) through the Safe Drinking Water Act, the state of North Carolina h~ developed a water supply classification system. The purpose of the system is to (1) determine the suitability of waters for public consumption after approved treatment in reference to its physical, chemical and bacteriological characteristics, and (2) provide a system of established controls and methods by which these supplies can be protected from potential sources of pollution. The Coddle Creek watershed is classified by the state of North Carolina as a WS-II watershed. North Carolina describes a WS-II classification as the following: · Applies to predominantly undeveloped water supply watersheds; · Limits new development in critical areas to one dwelling unit per 2 acres or 6 percent built- upon area with the low-density option, or 24 percent built-upon area with the high-density option; and · New development outside critical areas is limited to one dwelling unit per acre or 12 percent built-upon area with the low-density option, or 30 percent built-upon area with the high- density option. (The critical area is defined as the area 0.5 mile from the high-water mark of the reservoir or the ridge line of the watershed, whichever is closer to the reservoir.) Local governments may choose whether new development within the watershed will be low or high in density. Low-density development allows less area to be built upon than high-density development, and therefore does not require the construction of sto~mwater control systems. High-density development, however, does require stormwater control systems for the higher percentage of built-upon area. Built-upon area refers to that portion ora development project that is covered by impervious or partially impervious surfaces, such as buildings, pavement, and I
