Sewer Hydraulic Study
O’Brien & Gere was subcontracted by Gulf Engineers to provide hydrological and hydraulic calculations using USEPA’s Storm Water Management Model of the existing drainage system in the west and northwest areas of Louisville, Kentucky. Gulf Engineers was performing this contract for the US Army Corps of Engineers, Louisville District. O’Brien & Gere’s work included examining preliminary alternatives that might reduce the potential for surface flooding and basement back-ups during intense precipitation events. The study area covered 15,000 acres including historic Churchill Downs, the University of Louisville, and the Kentucky Fair and Exhibition Center.
A total of 29 locations were identified as locations with considerable surcharge and/or surface flooding. Upon completion of the simulation of these storms and river stages, surcharge volume estimates and maximum water surface elevations were compiled from the 29 locations.
