This is a set of construction design plans and specifications for stormwater management facilities at a military installation. The document provides comprehensive engineering drawings and detailed specifications for the installation of stormwater infrastructure including storm structures, pipes, sediment management facilities, erosion and sediment control measures, and associated site work.

The plans detail the construction of multiple storm drainage structures (numbered S01-S049), storm pipes (numbered with connections and specifications), and stormwater treatment facilities including filter sand systems, bioretention areas, sediment chambers, and outlet protection structures. Key construction specifications address erosion and sediment control requirements, temporary inlet and outlet protection measures, maintenance access provisions, tree preservation and protection protocols, and stockpile management. The document includes storm structure data tables specifying dimensions, invert elevations, and pipe connections; roof drain notes indicating drain sizing and placement; and detailed cross-sections and elevation drawings of bioretention outlet structures, trash rack assemblies, sediment chambers, and various inlet protection devices. Additional requirements cover North Carolina seeding specifications for temporary and permanent ground cover, construction entrance details, dewatering and sediment management procedures, and ongoing maintenance protocols for inspecting and cleaning sediment control measures. The plans reference related detail sheets and specifications for complete construction requirements and indicate compliance with erosion control design standards.
