Full Public Notice     Project Plans     Mitigation Plan

PROJECT DESCRIPTION:  The applicant proposes to construct improvements to the shoreline of the Sabine-Neches Canal and to upgrade the port facility structures within the boundaries of the Port of Port Arthur.  The applicant proposes to discharge fill material into 3.26 acres of open waters and 0.08 acres of wetlands to expand the port facilities and convey drainage with new concrete box outfall culverts and pipes.  The applicant will install one new breasting dolphin and one new mooring dolphin to replace structures removed during construction of the new port facilities. The applicant will construct a new 600-foot-long by 63-foot-wide wharf with driven concrete pile supports that will incorporate an existing rail bridge and two newly constructed additional railroad spurs.  The applicant will mechanically and/or hydraulically dredge 18.31 acres to 3:1 slopes within the Sabine-Neches Canal to a depth of -48 feet mean low tide plus 2 feet overdredge plus 1 foot advanced maintenance removing 454,300 cubic yards of material.  The dredged material will be piped by placement of a pipe across the Sabine-Neches Canal from the dredge areas into Corps Dredged Material Placement Area #8.  Beneath the proposed wharf, the applicant proposes to construct a 398-foot-long sheet pile bulkhead.  The applicant proposes to straighten and armor 1,198 linear feet of shoreline beginning at the end of the proposed bulkhead and ending near the State Highway 82 Bridge.  The shoreline beneath the proposed wharf and subsequent 1,198 linear feet will be contoured to a 3:1 slope and be overlaid with a total of 10.38 acres of articulated concrete matting.  Some areas along the shoreline will also have stone riprap installed at the slope toe. The applicant does not propose maintenance dredging.
