W ODARD <br /> &CURRAN <br /> 3.1.4 City of Lathrop Projected Demands <br /> The City updated its citywide water demand projections through 2040 as part of developing its 2019 WSMP. That <br /> projection was based on historical water use,population,and employment projections.Those projections were recently <br /> revised, based on more current usage data. As shown in Table 19, the River Islands development is projected to <br /> account for about 39 percent of the citywide potable demand at buildout. <br /> Table 19: City of Lathrop Projected Demands through 2040 <br /> Projected Water Use AFY <br /> 2020 2025 2030 2035 2040 <br /> Buildout <br /> Potable Demands <br /> City of Lathrop' 4,794 6,076 6,584 6,678 7,129 <br /> River Islands Phase 1 Demand2 779 1,287 1,387 1,476 1,565 <br /> River Islands Phase 2 0 268 1,186 2,112 3,038 <br /> Total City Demand3 5,573 7,632 9,157 10,266 11,732 <br /> Non-potable Demands <br /> City of Lathro 4 1,006 1,736 2,444 2,906 3,358 <br /> River Islands Phase 1 Demand 153 258 341 351 361 <br /> River Islands Phase 2 0 109 276 518 760 <br /> Total City Demands 1,159 2,103 3,061 3,775 4,479 <br /> Notes: <br /> 1.
