DEP Issues Permit for Herbert Hooker Dike Repair

On Friday, the Department of Environmental Protection’s Office of Ecosystem Projects issued a consolidated Environmental Resource Permit, or ERP, to the United States Army Corps of Engineers for the Herbert Hoover Dike (HHD) Repair and Rehabilitation Project (R&R Project). The permit authorizes construction and replacement of Culverts 2, 12A and HP-2 with new water control structures S-278 (C-2), S-274 (C-12A) and S-287 (C-HP-2).

The department estimates this proactive comprehensive approach will save over 1,000 work hours, more than $40,000 in tax payers money and will result in a significant reduction in time needed for future permit authorizations.

The HHD R&R Project is intended to reduce the risk of flooding, piping and seepage as a result of higher lake levels. The dike, which was constructed in the early to mid-1900s, is comprised of gravel, rock, limestone, sand and shell and does not currently meet the rigorous standards for dams and levees that exist today; limiting the flexibility of water managers with regard to lake operations. Enhancements to the HHD are critical to the restoration of the Everglades, and last year, the state urged the U.S. Army Corps of Engineers’ (Corps) to expedite work on this dike system. The HHD R&R Project has been ongoing since 2007 and is estimated to have all culverts replaced by 2018.
