Replacement of a bridge on Fee Fee Road in Maryland Heights, Missouri required relocation of a small stream channel. Steve Gough was given the task of geomorphic assessment and conceptual design. His design for the previously channelized reach included three meander bends and hydraulic energy management using grade control structures. Steve’s design was particularly innovative in shifting an existing knickpoint upstream to greatly improve hydraulic capacity through the bridge, and through this method, he was able to solve a seemingly intractable conveyance problem. His design also included composite revetments and a two-stage channel. This is perhaps the first use of a two-stage channel under a bridge in the midwestern United States. The design has performed very well through a 10-year event and its environmental and aesthetic values are a point of pride for the city. Steve also provided pre-construction survey and stakeout, close supervision of construction, and has built surveys.
The St. Louis Chapter of the American Society of Civil Engineers awarded Steve its Outstanding Civil Engineering Achievement Award for this project.
