Based on Gross (Total) NPW Irrigation Areas shown in Table 2-1 and modified per the actual net NPW <br /> irrigation area shown in Table 2-2. <br /> 2.2 Non-Potable Water Irrigation Areas- Phase II <br /> River Islands is planning on expanding the Phase I NPW distribution system to service irrigation demands <br /> within Phase 11. For Phase 11, irrigation coverage exhibits have not been developed yet, however River <br /> Islands has mapped out the approximate location of commercial areas, schools, and parks as shown in <br /> Odell Phase 11 Lotting Exhibit(see Appendix E)and the River Islands Preliminary NPW Irrigation Map(see <br /> Appendix H). Commercial and school property on-site irrigation with NPW has not yet been approved in <br /> Lathrop by the regulatory agencies, but this use has been successful in other areas, and there is no reason <br /> it cannot be expanded to work in River Islands. Similar to Phase 1, Table 2-4 lists the gross (total) NPW <br /> areas, the percent irrigation areas for each land use type, and the Net NPW irrigation areas for Phase II. <br /> Table 2-5 summarizes the total Phase I and 11 Net NPW Irrigation Areas for the development. <br /> 8 <br />
