Notice of intent.


The purpose of the project is to reconstruct and rehabilitate Reach 1 of the Herbert Hoover Dike to prevent catastrophic failure of the system to retain the waters of Lake Okeechobee. On July 8, 2005, the Jacksonville District, U.S. Army Corps of Engineers (Corps) issued a Final Supplemental Environmental Impact Statement (FSEIS) for the Major Rehabilitation actions proposed for Herbert Hoover Dike (HHD), Reach One. Herbert Hoover Dike is the levee that completely surrounds Lake Okeechobee. On September 23, 2005, a Record of Decision was signed adopting the preferred alternative as the Selected Plan for Reach One.

As plans and specifications were developed for Reach 1, it became apparent that the cut-off wall with seepage berm alternative would not work for all of Reach 1. The alternative for Reach 1 will be a combination of one or more of the following features dependent on the geology and adjacent land factors with the cut-off wall: Seepage Berm, Relief Trench, Soil Replacement Wedge, Relief Wells, Drainage Feature and Sand Columns. Reach 1 of the HHD extends for approximately 22.5 miles within Martin and Palm Beach Counties, from the St. Lucie Canal at Port Mayaca, south to the Hillsboro Canal at Belle Glade, FL. This study is a cooperative effort between the Corps and the South Florida Water Management District (SFWMD).

a. The proposed action will be the selected plan described in the July 2005 Supplemental Environmental Impact Statement (SEIS) with the additional action of implementing the landslide rehabilitation features as needed based on geology and adjacent land factors. The proposed action will not affect the Regulation Schedule for Lake Okeechobee. Land may have to be acquired outside of the existing right-of-way (ROW) and this EIS will account for any impacts that result due to acquisition of additional real estate.

b. Alternatives to be considered separately for each subdivision of Reach 1 are dependent upon the geology and adjacent land factors with the cut-off wall. Reach 1 is divided into Subreaches A, B, C and D. The alternatives to be implemented include one or more of the following features: Seepage Berm, Relief Trench, Soil Replacement Wedge, Relief Wells, Sand Column and Drainage Feature.

c. A scoping letter will be used to invite comments on alternatives and issues from Federal, State, and local agencies, affected Indian tribes, and other interested private organizations and individuals. The scoping letter will be sent out in October 2007. A scoping meeting is not anticipated.

d. A public meeting will be held after release of the Draft Second Supplemental EIS. The public meeting is anticipated to be held in July 2008 in Clewiston, FL. The exact location, date, and times will be announced in a public notice and local newspapers.

e. A Major Rehabilitation Evaluation Report (MRR) was approved by Congress in the Water Resources Development Act (WRDA) 2000 that addressed the need to repair the aging dike.
