100-Year Levee Fixes

Public safety is the number one priority for the City of Dallas in all areas. For the Dallas Floodway, the Levee System protects lives and billions of dollars in property value.

After Hurricane Katrina, a National Levee Safety Program was instituted resulting in more rigorous and nationally uniform criteria for inspecting levee systems. Under this new criteria, the U.S. Army Corps of Engineers (Corps) issued Periodic Inspection No. 9 in March 2009 and rated the Dallas Levee System "Unacceptable". As a result, the City lost its 100-Year accreditation of the levee system which began FEMA's process to remap the areas behind the levees.

The City went into action to complete the 100-year flood protection improvements and to work with the Corps on the levee fixes which included 198 Operations and Maintenance (O&M) Improvements.  There were also public meetings held throughout the City and a number of other initiaitives to keep the public updated on the process. The City completed the O&M Improvements in 2012.  In February 2012, the City received the Corps' approval on the Section 408 application for the City's proposed 100-year levee fixes and installed 3.0 miles of cutoff walls at the East Levee and 0.5 mile of cutoff wall at the west level.​​​​​​​

The City and Corps continue their regular meetings and work to provide the highest level of public safety and direct oversight of the entire allas Floodway system, one of the largest systems in the nation.
