Cherry_Point_Crossing_P&Z_SW_Permit.pdf

This is a Planning and Zoning Stormwater Permit for a project in Beaufort County, South Carolina, involving the installation of stormwater infrastructure at the Cherry Point Preserve property. The project scope includes the installation of a 60-inch reinforced concrete pipe (RCP) culvert to maintain drainage flow across an existing ditch that bisects the county-owned parcel, along with a gravel-stone surface crossing above the pipe to facilitate staff access from the entrance gate to the eastern portion of the property. The drainage system analysis was conducted using the Rational Method to model the 100-year storm event, with combined upstream drainage areas sized to accommodate a flow rate of 103.42 cubic feet per second. Minimal tree removal is anticipated, with culvert design specifically developed to avoid impacts to significant or specimen trees. The project is located on Beaufort County parcel TMS #R600 013 000 0061 0000, situated parallel to Pritcher Point Road with coordinates at N 180729.01 E 2023742.96 (N32 19 47.977 E279 04 36.688).

No utilities are proposed as part of this project, as the site remains unoccupied. The existing drainage infrastructure includes a 30-inch pipe extending from the Malind Bluff subdivision that initiates the ditch system, which naturally widens moving northeast toward the Okatie River. The permit documentation confirms that stormwater currently flows through the existing ditch toward the Okatie River, and the proposed crossing is designed to maintain uninterrupted flow while enabling necessary county access across the drainage feature.
