<br />7A - ATTACHMENT NO.3 <br />Saltworks Proposal- Water Group Summary Report (22 January 2010) Page 63 <br /> <br />team this transfer is its primary and potentially sole proposed source of potable supply <br />for the project. <br /> <br />The water team makes the following findings about each supply source: <br /> <br />Potable SUDDlies <br /> <br />. Redwood City municipal water - The City's 2005 UWMP shows that in 2030 <br />the City plans to use 11,724 AFY from the SFPUC, which is 519 AFY less <br />than their supply guarantee of 12,243 AFY. The 2030 projection does not <br />include the Saltworks project. The 519 AFY may be available for a project like <br />the Saltworks. The Saltworks potable water demand, using the City's <br />Attachment Q methodology, is about 1,815 AFY. Thus, existing potable <br />supply is considered by the water team to be to insufficient to meet existing <br />City demand plus the estimated Saltworks potable demand as summarized in <br />Table 3. The 2005 UWMP is scheduled to be updated in 2010 to be <br />consistent with the new General Plan (also scheduled for adoption in 2010). <br />The General Plan may include demands that are not included in the 2005 <br />UWMP and which could exceed the City's current SFPUC Supply Assurance <br />of 12,243 AFY. <br /> <br />. Groundwater - OMB identified groundwater as the source of 700 AFY, and <br />subsequently revised the water supply proposal so that groundwater is no <br />longer a planned supply source. Because the Saltworks project may need to <br />rely on a range of water supply options, the viability of groundwater as a <br />supply source at the site was evaluated. The water team concludes that <br />insufficient information is available to confirm the feasibility of obtaining 700 <br />AFY at the site. OMB indicated that reverse osmosis would be needed to <br />treat groundwater, and the water team concurs that treatment of this type <br />would likely be needed. Substantial additional study would be needed to <br />establish the reliable groundwater yield and impacts of groundwater pumping. <br /> <br />. Local and regional potable water offsets - Implementing offset projects either <br />within the City or SFPUC service areas has the potential to realize significant, <br />reliable long-term potable water supply. The City and the SFPUC have <br />identified 2,000 to 5,000 AFY offset potential from recycled water projects <br />alone. Each project would involve hurdles such as enlisting cooperating <br />partners, carrying out agreements with individuals and agencies including in <br />some cases the SFPUC, and permitting and CEQA compliance. <br /> <br />. OMB surface water transfer - OMB proposes to utilize a transfer of Nickel <br />Family water for the Saltworks project. This proposal was not included in the <br />OMB application materials to the City. OMB provided information about the <br />proposal to the water team later than other materials. Nickel water appears <br />to be quite reliable. The amount of Nickel water owned by OMB (8,393 AFY) <br />is greater than the estimated potable demand of the Saltworks project (1,825 <br />AFY). OMB owns the Nickel water for 70 years. The proposal requires <br />participation and approval of other public agencies. The proposal also <br />requires further details regarding infrastructure requirements necessary to <br />facilitate the transfer. These details depend in part on the identity of the other <br /> <br />56 <br />
