Abstract: This appendix presents the discussion of applicable design considerations and construction methods utilized to adequately address the project requirements and to establish a basis for the cost estimates. General requirements for real estate and operation and maintenance are also presented. The recommended plan incorporates National Economic Development (NED) improvements to the Federal navigation project at Lake Worth Inlet, Florida. These improvements would include the addition of a new channel flare on the south side of the Entrance Channel, a widening of the Entrance Channel by either 40’ or 60’ to the north, widening of the Inner Harbor Cuts 1 and 2 to provide for a minimum channel width of 450’, a 150’ expansion of the Southern (Main) Turning Basin to the south, and an expansion of the Southern (Main) Turning Basin on the north side to remove a notch currently encroaching into the basin. The channel would be deepened to a project depth of 39 feet Mean Lower Low Water (MLLW) for the Inner Harbor and 41 feet MLLW for the Entrance Channel plus applicable allowances and overdepths discussed in this Appendix. Refer to Plate 2 for a complete description of the NED project improvement features. In addition to the navigation project improvements described above that are necessary to facilitate the safe and efficient navigation of the design vessel, there are other features needed to support the project. These features include North Jetty stabilization, reconfiguration of the Advance Maintenance Zones, reconfiguration of the Settling Basin, Seagrass Mitigation Area construction, and Hardbottom Mitigation Area construction as detailed in this Appendix and other areas of the Feasibility Study Report. A discussion of the plan formulation involved in the selection of the Recommended Plan is presented in the main portion of this report. All soundings presented in this report are at MLLW based on the latest tidal epoch available from NOAA and the project is located geospatially in the North American Datum of 1983 (NAD83).
