U.S. Army Corps of Engineers award $6.8M contract to continue and complete the Modified Central City North Bypass Channel design

By May 12, 2023

Today, the U.S. Army Corps of Engineers, Fort Worth District, awarded an architect-engineer contract totaling $6.8 million to continue and complete the design of the North Bypass Channel in support of the Modified Central City Project.

The A-E contract was awarded to CDM-Stanley Joint Venture – the team who previously developed the 60 percent design.  The work includes completing the design of the north bypass channel, which is approximately 3,900 feet of the overall 8,400 feet of bypass channel.

“With this $6.8 million design contract award, the U.S. Army Corps of Engineers continues the progress in delivering the Modified Central City Project with our sponsor, Tarrant Regional Water District, and stakeholders. We now have the full team onboard, and we are ready to roll-up our sleeves and complete the design so we can move into construction,” said Program Manager Kalli Egan.

The Fort Worth Floodway levees were originally constructed by local community interests in response to flooding events in the early 1900s. This system was modified in the 1950’s and incorporated as a congressionally authorized project.  The Fort Worth Floodway is a federally authorized and non-federally operated and maintained, urban flood risk management system. The current system, as we know it today, was constructed in the 1960s.  As a result of congressionally authorized floodway studies, it was determined that modifications (as defined by the Modified Central City Project) are required to reduce flood risk.

The project is in Fort Worth, Texas. The Modified Central City Project has various components including an approximate 8,400-foot bypass channel, three isolation gates, and valley storage mitigation sites (Gateway Park, Ham Branch, Riverside Park, Rockwood Park West, Samuels Avenue, and University Drive) to provide flood risk management functions along the Clear Fork and West Fork of the Trinity River.
