The attached stormwater management plan is provided for your use to address the additional information requested. Item 1. Even though Stafford Land Company will not likely be responsible for constructing the road that is anticipated in the western corner of the property, we will include it in the proposed impacts (see drawing sheet C-1.0 "Stormwater Management Existing Conditions/Demo Plan"). This impact is labeled Disturbed Wetland Area 3 and is 0.037 acre in size. This increases the total wetland impacts for this project to 0.24 acre. Item 2. The attached plans include cross-section details at a scale of 1"=50'of the two culverts proposed to allow for aquatic life passage (see drawing sheet C-6.1 "Stormwater Management Plan Culvert Cross Sections"). Item 3. DWQ has misidentified this project as located in a Water Supply Watershed IV Critical Area (WS-IV CA). According to the Stormwater Program Interactvie Mapper (see screenshot below), this project is located within a Water Supply Watershed IV Protected Area (WS-IV PA). High-density development within WS-IV PA is allowed up to 70% percent built-upon area. The impervious acreage for this project is 54%. The stormwater management plan was submitted to the Town of Lillington for review on 16 January 2008, and a watershed protection permit was issued on 22 January 2008. Copies of the approved stormwater management plan and approval document are attached. Soil Science Investigations • Wetland Delineations, Permitting, and Consulting HAL OWEN & ASSOCIATES, 1NC. N. G.
