Trinity River Levee System Reaccreditation
An unprecedented alliance protects downtown Dallas real estate from flood-plain status and approaches completion of FEMA’s levee reaccreditation process
• 17,000 acres escape flood-plain designation
• Dallas is first to navigate Corp Section 408 process and near completion of reaccreditation process
• Documentation creates a proven process for other cities to emulate
HNTB, the City of Dallas and the U.S. Army Corps of Engineers worked together to save 17,000 acres of prime downtown Dallas real estate from being reclassified as residing within a 100-year flood plain.
The unprecedented alliance makes Dallas the first major metropolitan area to successfully navigate the Corps’ Section 408 process, begin 100-year levee remediation construction and draw closer to completing the Federal Emergency Management Agency’s extensive levee reaccreditation process.
Because HNTB and its partners carefully documented the process, other cities that receive unacceptable flood-plain ratings from the Corps now have a proven process to emulate.
