surface area per acre of property with the incorporation of stormwater control <br />devices. <br />At the writing of this memorandum the Project proposes the development of <br />several stormwater devices, which would potentially allow up to 70% impervious <br />surface area on the Property. <br />b. Seven Mile Creek Preserve: The Project is approximately 1 mile north of the <br />County’s Seven Mile Creek Natural Area and the Seven Mile Creek Natural <br />Heritage Area, as defined/ inventoried in the North Carolina Natural Heritage <br />Program. <br />The Seven Mile Creek Natural Area is a County designated preserve, which is <br />also a part of the 366 acre Upper Eno Nature Preserve, acquired throughout the <br />1970’s and 1980’s at a time when a possible future reservoir was being <br />considered. Once the need for the reservoir was eliminated, the County began <br />conservation efforts to maintain the area as a natural area. <br />The County designated natural area includes portions of two significant natural <br />heritage areas, specifically the ‘Crabtree Creek Monadnock Ridge’ and the <br />‘Sevenmile Creek Sugar Maple Bottom’ featuring large stands of southern sugar <br />maples, hackberry and swamp chestnut oaks and serves as a host for several <br />state listed rare plants and significant wildlife species. <br />ENVIRONMENTAL REVIEW: <br />I. COUNTY DOCUMENT(S): <br />a. Unified Development Ordinance (UDO): <br />i. Per Section 6.13 Stream Buffers, identified water features (i.e. <br />streams, hydrologically connected ponds, wetlands, etc.) are <br />required to be left undisturbed. The width of this required natural <br />area ranges from 65 ft. to 80 ft. based on the slope of the property <br />in and around the water feature; <br />STAFF COMMENT: The submittal indicates identified water <br />features will be located within designated open space areas, <br />with vegetation either being preserved or re-established <br />consistent with applicable County standards. <br />Please note: the applicant has the ability to seek a permit <br />from the US Army Corps of Engineer to locate a roadway <br />within/adjacent to identified wetland areas. The proposed <br />driveway off of Mt. Willing Road will be required to secure a <br />permit before development activity can occur. <br />Section 6.13.6 of the UDO lists various development <br />activities that are permitted within identified stream buffers, <br />which include roadway development. <br />ii. Impervious surface: The Property is located within the Upper Eno <br />Protected Watershed Protection Overlay District. Per Section 4.2.6 <br />Impervious Surface/Detention Pond Requirements for Non- <br />109
