-20- <br />primarily due to complex geologic site conditions encountered during construction that were <br />different than conditions understood during the design phase, resulting in construction change <br />orders, including significant additional excavation quantities for the dam abutments and <br />foundation, disposal of excavation materials and other unusable spoil materials from borrow <br />areas, import of rockfill materials to replace unusable spoil materials, and acceleration of the <br />project construction schedule. Budget increases for the ACDD were primarily due to necessary <br />changes in the design of the fish ladder and appurtenances to accommodate existing site <br />conditions and operational requirements. The current forecast date to complete the overall <br />WSIP is December 2019. <br /> <br />Further information regarding WSIP, including periodic updates and status reports, is <br />available at www.sfwater.org. <br /> <br />Recycled Water. The Enterprise currently receives recycled water from Silicon Valley <br />Clean Water (the “SVCW”), formerly the South Bayside System Authority. In Fiscal Year <br />2015-16, deliveries of recycled water from the SVCW totaled 746 acre feet, or approximately <br />6.0% of the Enterprise’s total water supply. Phase 1 of the Recycled Water Project was <br />completed in 2010. The City expects recycled water demand from SVCW of approximately 892 <br />AFY by Fiscal Year 2019-20 which would constitute approximately 7.3% of the Enterprise’s total <br />water deliveries. <br /> <br />Tables 1 and 2 below shows water supplies and water demand for the Enterprise for the <br />five most recent fiscal years. Table 1 shows the City’s ISG of 12,243 AFY under the Water Sales <br />Contract and the City’s water surplus or deficit based solely on the assured water supply. <br /> <br />Table 1 <br />Historical Water Supply and Demand, Excluding Recycled Water <br />Annual Production (Acre-Feet) <br /> <br />Source of Water FY 2011-12 FY 2012-13 FY 2013-14 FY 2014-15 FY 2015-16 <br />Assured supply (1) 12,243 12,243 12,243 12,243 12,243 <br />Regional Water System Demand 10,148 10,897 10,118 8,698 8,054 <br />Surplus/(deficit) (2) 2,095 1,346 2,215 3,545 4,189 <br /> <br />Source: City of Redwood City Public Works Services Department; 2015 Urban Water Management Plan. <br />(1) Assured Supply data derived from the City ISG with SFPUC. <br />(2) Assured Supply less Demand. <br /> <br />Table 2 <br />Historical Recycled Water Supply and Demand <br />Annual Production (Acre-Feet) <br /> <br />Source of Water FY 2011-12 FY 2012-13 FY 2013-14 FY 2014-15 FY 2015-16 <br />Recycled Water Production Capacity 3,238 3,238 3,238 3,238 3,238 <br />Recycled Water Demand 586 797 784 755 746 <br />Surplus/(deficit) (1) 2,652 2,441 2,454 2,483 2,492 <br /> <br />Source: City of Redwood City Public Works Services Department. <br />(1) Recycled Water Supply less Recycled Water Demand. <br /> <br />The 2015 Urban Water Management Plan for the Enterprise predicts that with <br />conservation savings, estimated annual water demands associated with buildout of the City's <br />2010 General Plan will be approximately 12,059 AFY in 2020 and 13,697 AFY in 2040 for both <br />potable and recycled water uses.
