DRAFT 56 (4) Woodgreen (25 Lots - Cheeks Township) Presentation by Karen Lincoln. The Preliminary Plan for Woodgreen follows the conservation option of flexible development as described in the Subdivision Regulations. The applicant, Tri-Star, Inc., proposes to subdivide the property (30.7 acres) into 25 new residential lots with an average lot size of 1.03 acres (smallest lot size of 0.92 acre). The proposal includes 11.04 acres or 36% open space. The property is located in Cheeks Township at the southern intersection of Moorefields Road (SR 1135) and Dimmicks Mill Road (SR 1134) on the east side of Rocky Run Creek as shown on the vicinity map. The current zoning is Agricultural Residential (AR) and Upper Eno Protected Watershed. The maximum amount of impervious surface in new residential development, outside of Transition Areas, within the Upper Eno Protected Watershed is limited to twelve percent. Adjacent land uses are residential. The total acreage of the tract is 30.7 acres. Most of the property is wooded except for a 4 -acre open field in the central portion of the site, which is also a ridge top at the highest part of the site. In addition, a 2 -acre open area is located at the southeast comer at the intersection of Dimmocks Mill Road and Moorefields Road. Hardwoods dominate the western two-thirds of the forest on the west side of the ridge. Pines are predominate on lots 1 through 6 east of the ridge line. The majority of the site slopes gently at a gradient less than 7.5 %. Approximately two -thirds of the site drains directly into rocky Run which flows north along the western boundary. The eastern third of the site drains to the north and eventually to Rocky Run downstream of Woodgreen. A small area of moderate slopes (7.5% to 15 %) is found in the required stream buffer near the southwest comer of the site. The open space will be privately owned as part of the lots and will be reserved through a conservation easement or restrictive covenants. Open space will protect wooded land on gentle slopes, Rocky Run, the 100 -year floodplain, the adjacent stream buffer, buffers along Dimmocks Mill Road and the eastern subdivision boundary, as well as the natural drainage swale across lots 1 through 7. The open space will also minimize visual impacts of the subdivision by preserving the open area adjacent to Dimmocks Mill Road. The lots will have individual wells and septic systems. The Health Department has authorized that each lot contains provisionally suitable soils sufficient to locate a septic system to accommodate a three bedroom house. A PPBS system is recommended for lots 3, 4, 5, 10, 11, 12, and 15. A prefabricated, permeable block panel system is a specially constructed type of trench, that is state approved, that allows a 50% reduction in nitrification trench over a conventional system. Remaining lots have been approved for an innovative type system which is the type of system requested by the developer. An innovative system is one of five types of space reducing systems approved by the state. The design flow, type of system, and pump
