SWG-2024-00099 - Lisa Halili-Razz Halili Trust - Dickinson Bayou - Galveston County, Texas

Public Notice          Project Plans

The applicant requests authorization for the following activities: To install 4,300 linear feet of vinyl sheet bulkhead into 0.05-acre of four EEM wetlands (Wet 3, 6, 7, and 9), of which, 1,400 linear feet will be below the mean high water of Dickinson Bayou. The vinyl sheet pile bulkhead will measure approximately 5 feet in height above mean high water and will be installed using a vibratory hammer.

To discharge 300 cubic yards (CY) of stone material into 0.25-acre of 5 PEM wetlands (Wet-3, Wet-4, Wet-6, Wet-7, and Wet-8) and into 0.35-acre of Dickinson Bayou to install 1,300 linear feet of riprap bank stabilization intermittently along the face of the bulkhead in areas where extra shoreline protection is needed. Riprap will be delivered to the site via a heavy-haul truck and installed from the land using an excavator or long reach excavator.

To discharge approximately 22 CY of concrete material into 0.2-acre of one PEM (Wet-3) to install a 1,700-foot-long by 25-foot-wide concrete boardwalk surrounding the perimeter of the new access channel and north along the property boundary shoreline to a termination point with the adjacent property. The concrete boardwalk will have anchor points installed to tie-off and moor vessels within the access channel. In order to construct the boardwalk, a concrete truck will access the construction site and pour concrete within the designated boardwalk locations.

To hydraulically and/or mechanically dredge a total of approximately 54,700 CY (3.44 acres) of material, of which 27,300 CY will be from a 1.02-acre area of Dickinson Bayou and 0.39-acre area of Wet-3 to create a new 1,000-foot-long by 150-foot-wide entrance channel to -11 feet mean low lower water (MLLW). All dredge material will be placed within three onsite upland placement areas (Disposal Area 1, Disposal Area 2, and Disposal Area 3). The height of the containment berm for each disposal area will range between 6-10 feet, depending upon amount of material placed within each disposal area and settlement of that material. Containment berms will have crests measuring approximately 5-foot in width and bottom widths measuring approximately 45-65 feet in width with 3:1 side slopes.

Additionally, the applicant proposes to construct a new permanent 500-foot-long by 20-foot-wide access road constructed wholly within uplands and to stage construction equipment in a temporary one-acre construction staging area located on-site wholly within uplands.
