| Abstract: | The U.S. Army Corps of Engineers, Jacksonville District (Corps), is proposing to conduct maintenance dredging of the Okeechobee Waterway (OWW) Federal navigation project from the intersection with the Intracoastal Waterway (IWW), known locally as the Crossroads, to the St. Lucie Lock in Martin County, Florida. This Environmental Assessment (EA) will evaluate the operation and maintenance dredging of Reach I, II, III, and IV, spanning approximately 15.5 miles of the OWW with placement of dredged material into the previously authorized and constructed Dredged Material Management Area (DMMA) O-7 or within the pending construction DMMA O-23. DMMA O-7 is located approximately 2,344 feet west of the St. Lucie Lock and Dam. DMMA O-23 is located to the south of 1310 NE Business Park Place, approximately 0.55 miles north of the OWW shoreline. The federal channel would be maintained to its authorized dimensions: 8 feet below Mean Low Water (-8 ft MLW), plus 2 feet overdepth, by 80 feet. The current projections for removal of material within the channel is 42,000 cubic yards for Reach III and 31,000 cubic yards for Reach IV. The removal volumes for Reaches I and II will be located, calculated, and designed at a later time as funding allows. |
