About this file
This is a Stormwater and Industrial Waste Water Map for Naval Support Activity South Potomac - NSF Indian Head, Stump Neck Annex, dated 13 December 2022. The map provides detailed hydrological and infrastructure data for the facility located in Maryland near the Potomac River and Mattawoman Creek.
The facility encompasses two primary areas: Stump Neck and Cornwallis Neck, divided into nine watersheds with varying levels of impervious surface. Stump Neck totals 1,113.3 acres with 45.03 acres of impervious surface (4.04% imperviousness), while individual watersheds range from 0.72% to 20.38% imperviousness. Cornwallis Neck watersheds range from 10.74% to 19.59% imperviousness. The map illustrates stormwater infrastructure including outfalls, structural best management practices (BMPs), storm sewer lines, open stormwater drainage, culverts, and industrial discharge points. Problem areas are identified as priority or non-priority repairs for stormwater management. The facility includes buildings, structures, paved and unpaved roads, wetlands, surface water bodies (perennial, intermittent, and ephemeral), and adjacent land uses including the Chicamuxen Wildlife Management Area and commercial forestry operations operated by Glatfelter Pulp and Paper Company. The map scale is 1:4,674 and is marked "For Official Use Only."
