Baylor Grove Stormwater Management Permit Application August 31, 2023 Stormwater Narrative: This project is located on Pageland Highway (Hwy 601), in Union County, NC, approximately one mile southwest of the intersection of Hwy 601 & SR 1005 (Landsford Road), towards SR 1921(Stack Road)at the North Carolina/South Carolina state line.The proposed development of the site includes grading of vegetated roadside ditches, construction of a public cul-de-sac street, and subdivision of 21 residential lots (including one lot for an existing residence). The driveways shown on the construction documents are approximate and will be installed once the lots are sold and the home builder determines final pad locations and elevations. The home builder will be responsible for individual lot grading and erosion control measures, and installation of private wells and septic systems. The subdivision is designed as a low-density development and will remain less than 24% impervious coverage, including existing built- upon-areas. The vegetated roadside ditches are designed for the 10-year storm event, with 3H:1V side slopes and appropriate erosion control matting to ensure slope and channel stability. Calculations are provided on sheet C-2.3 of the construction documents. The soils on-site consist mostly of hydrologic soil groups B (Georgeville silty clay loam (GfB2), Tarrus gravelly silt loam (TaB), and Tarrus gravelly silty clay loam (TbB2)) and a very small area of C (Badin channery silt loam (BaB)). There are no streams or wetlands located on-site; most of the site is covered by dense, wooded vegetation. All on-site runoff is routed through vegetated road-side swales and discharged towards a natural low point along the southeastern property line, which eventually leads to Carolina Creek.
