  • Potable Water Supply. The majority of the increased potable water demand generated by proposed new development is expected to occur during the short-term planning period. The increase in short-term planning demand is spread almost evenly over Scenarios A, B, and C. The primary developments creating the greatest short-term demand include the renovated Intermodal Center to accommodate the relocation of the Port Authority's administration offices, terminal yard expansions, and the new cruise/ferry passenger terminal. The proposed auto import storage yard is expected to generate the greatest demand during the long-term planning horizon.

    It was not possible to determine potable water demand for Scenario D's PPP development. Table 4.6 summarizes the future demands for the individual short- and long-term development scenarios; details about these potable water demands are provided in Appendix C.

    As noted in Chapter 2 of this Plan, the demand flows reported in the 2009 Master Plan are presumed to be current. Present-day demands are estimated at 34,000 gallons per day. When both short- and long-term improvements are taken into account, potable water demand will nearly double with an additional 33,975 gallons per day. A new and larger potable water lateral to the Port from the water main on U.S. 41 was recently installed that will provide adequate capacity for future demand generated by expanded operations.

    Sanitary Sewer. Consistent with potable water, the sanitary sewer demand flows reported in the 2009 Master Plan are presumed to be current. Present-day demands are estimated at 6,200 gallons per day. When both short- and long-term improvements are taken into account, sanitary sewer demand will increase 67 percent with an additional 10,332 gallons per day. Based on growth and additional demands on sanitary sewer, plant capacity is adequate to treat the Port's current and future demands. As with potable water, the primary developments creating the greatest short-term sanitary sewer demand include the renovated Intermodal Center and the new cruise/ferry passenger terminal. The proposed auto import storage yard is expected to generate the greatest demand during the long-term planning horizon.

    It was not possible to determine sanitary sewer demand for Scenario D, PPP development. Details about the sanitary sewer demands for the individual short- and long-term development scenarios are provided in Appendix C. Table 4.7 summarizes the future demands.

    Electrical Supply. Growth at the Port between FY 2015/16 and FY 2019/20 will include new refrigerated warehouses, reefer plugs, yard lighting, cruise/ferry terminal renovations, relocation of the Port Authority's administration offices, and new berth construction with associated backlands. The major energy impact will be from the refrigerated warehouses described in Scenario A, which will add 230,000 square feet of cold storage. These two improvements constitute nearly 60 percent of the total additional demand during the short-term planning horizon. When the additional 60 reefer plugs are added in, the proportional energy demand increases another 10 percent. These improvements are needed to accommodate the anticipated growth in the volume of perishable cargo imported into the Port.

    The addition of new cranes for the container business will have limited effect on the energy supply as the cranes will be mobile and will generate their own power through on-board motors and generators. The backlands area will require high mast lighting. The demand from additional ship calls will be relatively small; energy needs for the additional vessels are handled by their own on-board generators.

    Another major energy impact, although not as significant as the refrigerated warehouses, is the new cruise/ferry terminal for passengers (renovated Shed #2). The new passenger terminal will account for 12 percent of the total additional energy demand during the short-term planning horizon. Details about the electric demands for the individual short- and long-term development scenarios are provided in Appendix D. It was not possible to determine electric demand for Scenario D, PPP development. Table 4.8 summarizes the future electric demands.
