Herbert Hoover Dike (HHD) is a 143-mile earthen dam that surrounds Lake Okeechobee, the heart of the Kissimmee-Okeechobee-Everglades system.  The project reduces impacts from flooding as a result of high lake levels for a large area of south Florida.

Since 2001, the Corps has made a significant investment, over $870 million, in projects designed to reduce the risk of catastrophic failure of the aging structure. Actions taken include installing a partial cutoff wall along the southeast part of the dike, removing and replacing water control structures (culverts), and conducting a variety of studies and technical reviews to help ensure the safety of south Florida residents. Corps teams work daily on the dike, providing contractor oversight, quality assurance, inspections, and dike operations and maintenance. Much progress is also being made behind the scenes at the District, where a team of engineers, hydrologists, geologists, scientists, contract and real estate specialists, budget analysts, and many others, work to ensure the very best rehabilitation strategies are applied to the dike today and in the future.

The HHD Project team maintains close coordination and communication with other internal Jacksonville technical offices such as Engineering, Planning, Contracting, Corporate Communication, Construction and Operations while maintaining a presence (HHD Project Manager forward) in the local project area to communicate regularly with local communities and the construction field offices regarding project updates and problem solving.
