Flood Control

The Trinity River Vision project is setting a new standard in flood control. The need for updated flood protection in the city's near north side, along with the community's desire for an urban waterfront, have led the project partners to develop an infrastructure that not only makes our city safer, but also provides a unique opportunity for river recreation and development. The infrastructure included in the Central City plan will eliminate the need for our current levee system – which allows people access right up to the waterfront edge.

Central City Project Breakdown

Three bridges will span the bypass channel providing vehicles and pedestrians with access between Panther Island and Northside neighborhoods.

1.5-mile-long bypass channel will be constructed to redirect flood waters around the low lying area to the north of downtown.

  • Because the bypass channel will be carrying water so quickly in times of flooding, areas where water can be stored before moving downstream will be critical. This is where valley storage comes into play. Valley storage is constructed to hold various amounts of water for short periods of time while river levels regulate after a flood.
  • Three flood gates will be installed at the portions of the river where the bypass channel and the original river intersect. These gates will remain open at most times, but can be shut during high water events – forcing water through the bypass channel.
  • A dam will be put in place near Samuels Ave. keeping the upstream water at a constant level at all times. The dam will also have a channel lock component allowing boats to travel from Marine Creek in the Stockyards all the way to Trinity Park!

Central City Bypass Channel Scale Model Hydraulic Study

To test the hydraulic validity of this system, the U.S. Army Corps of Engineers advised the TRV project team to assemble a 1-to-40 scale model of the new bypass channel and associated infrastructure. This football field-size replica of the future landscape not only provided a flood of data for project engineers, it saved the project partners millions of dollars in the long run.
