| dc.description.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. This Appendix has been prepared in accordance with the applicable policy guidance as contained in ER 1110-2-1150, Engineering and Design for Civil Works Projects; ER 1110-2-1403, Studies by Coastal, Hydraulic, and Hydrologic Facilities and Others; EM 1110-2-1613, Hydraulic Design of Deep-Draft Navigation Projects; ER 1110-2-1404, Hydraulic Design of Deep Draft Navigation Projects; and ER 1130-2-520, Navigation and Dredging Operations and Maintenance Policies. All soundings and elevations presented in this report are relative to Mean Lower Low Water (MLLW) based on the latest tidal epoch available from NOAA and the project is located geospatially in the North American Datum of 1983 (NAD83). The NED plan combines channel widening measures necessary for safe and efficient navigation of the project design vessels along with the deepening of the Federal channel project depth from existing depths to provide economic benefits. Existing Federal project depths for the relevant channel reaches range from -30’ to -42’ and would be deepened to -36’ to -46’ as shown on the Plates in this Appendix. The dimensions of the proposed expansion features are irrespective of the final depth chosen for the project and all features were applied to each foot of a 1-foot incremental analysis of additional depth to the existing project depths. An overview of the location and vicinity of the existing San Juan Harbor Federal Navigation project is shown on Plate 1. The non-Federal sponsor, the Puerto Rico Ports Authority (PRPA), has not requested a Locally Preferred Plan (LPP); therefore, the NED plan is the Recommended Plan, thus setting the project depths and channel dimensions for each segment as described in this Appendix. In addition, an expansion of Anchorage Area F for safety purposes is proposed by the United States Coast Guard (USCG) as a future-without project condition. A discussion of the plan formulation involved in the selection of the Recommended Plan is presented in the Main portion of this Report. Plan view details of the existing project and Recommended Plan are shown on Plates 2 thru 17. | en_US |
