This document is a supplemental information drawing (Sheet SI-006) for the National Cemetery of the Alleghenies Phase III Development, Package "A" located in Washington County, Pennsylvania. The detailed site plan shows a complex drainage and infrastructure layout including specific engineering elements such as a rip-rap outlet apron, 4" valve, 4" PVC solid pipe, stabilized overflow weir (width 45', elevation 1119.00), 4" perforated HDPE underdrain, and an infiltration berm with top elevation at 1120.00 and bottom elevation at 1117.00. The project is associated with the broader Y1JZ--NCOTA 3B Completion Project (Solicitation Number: 36C10F25B0002), which involves infrastructure improvements at the national cemetery.
