Part 7 of 7 Final Design Salem Stormwater Drawings_Addendum A.pdf

This document is a set of civil engineering design drawings for a stormwater drainage and water management project prepared by Mabbett for the VA Office of Construction and Facilities Management, specifically for the Samuel Odum Water Drainage project. The drawings are dated 100% Final Design and include project number CK501.

The design specifications encompass comprehensive stormwater management infrastructure including storable sediment control measures, bioretention areas, infiltration ponds, catch basins with multiple configurations, filter socks, headwalls, flared end sections for corrugated pipes, cleanout structures, trench drains, temporary silt fencing, subsurface infiltration systems, concrete median curbs, water connections to existing fittings, mechanical joint connections, and thrust blocks. Detailed civil details address pavement patches with and without rebar for various traffic conditions, drain manhole covers, catch basin inlet protection, standard steps for ladder rungs, stabilized construction entrances, and typical utility intersections. The drawings specify construction materials including concrete specifications for various applications, corrugated metal pipe connections, and protection requirements for existing infrastructure. Multiple sections and cross-sections provide dimensional requirements and installation procedures for erosion control, sediment management, and permanent stormwater conveyance systems designed to manage stormwater runoff through infiltration and controlled discharge mechanisms.
