Creation of Island Habitat in Jacksonville Harbor, FL
Abstract
Jacksonville Harbor, in Duval County, FL, begins at the mouth of the St. Johns River where it empties into the Atlantic Ocean (Figure 1). The Federally authorized Jacksonville Harbor navigation project provides deep-draft vessels access to terminal facilities located within the City of Jacksonville. Jacksonville Harbor also serves the US Navy and the US Marine Corps. The Jacksonville Harbor General Re-evaluation Report (GRR) is investigating deepening and widening the Federal navigation channel. The GRR will most likely identify about 20 million cubic yards (cu yd) of material to be dredged and placed. All of this new-work dredging material is Offshore Dredged Material Disposal Site (ODMDS)-quality, with most of this dredged volume assumed to be going into the Jacksonville Harbor ODMDS (Figure 1) because options for upland disposal are unavailable. This material could be more beneficially used to create complex island habitat in the St. Johns River, which would additionally save the GRR millions of dollars. This Coastal and Hydraulics Engineering Technical Note (CHETN) was prepared by the US Army Engineer District (USAED), Jacksonville (SAJ), as part of the Regional Sediment Management (RSM) program, to emphasize a least-cost and beneficial alternative for using dredged material not suitable for nearshore placement.
