72nd Street (2,1) acres is drained to the City sewer in 72nd Street. Discharge to this sewer is estimated at 3.0 cubic feet p-( per second. After the Trumpdevelopment and overbuild, of course, discharge will consist only of subsurface drainage, idiich will be a negligible amount. Our detail for the connection is on Sheet D-1. Ne are connecting to the 5* x 7* barrel since our data shows the upper 3' x 4* barrels to be sanitary sewers. In Area 3, the railroad is completely overbuilt by Riverside Park and the Henry Hodson Parkway. Ne do not plan any changes to the existing drainage system. Ne are cleaning oor drainage structures under a prior contract. In Area 4, drainage work consists of pipe and ditch . cleanout. Por the most part, culvert pipes in this area drain _ directly to the Hudson River. In you have any'questions, please contact Norman Satterthiraite at (215) 557-4274. Sincerely,
