Project: Design & Construction Supervision of
Jackson Street Storm Water Pipe Improvements
Client: City of College Park, Georgia
Location: Jackson Street in College Park, Georgia
Objective: To design a storm conduit to replace the structurally compromised corrugated metal pipe located at the southeastern side of Jackson Street at John Calvin Avenue. The project also provides for eliminating the safety hazard posed by the exposed junction box at that location.
In February 2007, MME was engaged by the City of College Park to develop detailed designs, construction-grade plans and Bid Documents for the Jackson Street Strom Drain Project. The project is located at the intersection of Jackson Street and John Calvin Avenue in the City of College Park.
At Jackson Street and John Calvin Avenue, storm water transitioned from open channel flow at the northwest side of Jackson Street into two (2) 54-inch concrete arch culvert pipes installed across and under Jackson Street. These twin culvert pipes exited at an open junction box on the southeast side of Jackson Street. From the exposed junction box, storm water runoff entered a single horizontal elliptical corrugated metal pipe, approximately 36 inches by 65 inches. The structural integrity of the corrugated metal pipe was seriously compromised with signs of extensive corrosion and significant deterioration. These deficiencies created the potential for flooding, inconvenience and damage to properties within the project area.
MME performed the hydrological and hydraulic analyses of the existing and proposed drainage systems and developed design criteria for the proposed conduit and junction box improvements. MME used the SWMM5 hydraulic model to estimate peak flows, evaluated the hydraulic capacity of the existing system, developed hydraulic profiles and sized the new pipe conduit.
