OVERVIEW <br />On January 12, 2007, the City of Redwood City (City) Public Works Services Department <br />received a request from the Planning and Redevelopment Division of the Community <br />Development Services Department to prepare a Water Supply Assessment (WSA) for the <br />proposed Peninsula Park Project (Project). This WSA has been prepared within the 90 <br />days allowed by State law for preparation of WSAs, and is presented to the Redwood City <br />Council for its consideration at its regularly scheduled meeting of February 26, 2007. <br /> <br />The proposed Project is estimated to result in a total new water demand of 107.9 acre-feet <br />per year (af/yr); this total demand includes a net new potable water demand of 80.8 aflyr <br />and a recycled water demand of 27.1 af/yr. The demand for the proposed Project <br />represents an approximate 0.6 to 0.7 percent increase in total potable water use for the <br />City. The water demand associated with the Peninsula Park Project was not identified in the <br />City's most recent Urban Water Management Plan (UWMP) adopted by the City Council on <br />December 19, 2005. Hence, this new water demand would be an addition to those demands <br />specified during that process. <br /> <br />This WSA determines that the City has sufficient water, in most years, to meet the expected <br />future water demands of the Project together with those of existing customers and planned <br />future development. During periods of water shortages, however, the Project would increase <br />the magnitude of cutbacks required by existing water customers and new customers <br />identified in the UWMP. In a single dry year scenario, the Project would increase potable <br />water cutbacks of other customers by an additional 0.74 percent. In a multiple dry year <br />scenario, the project would increase water cutbacks by an additional 0.85 percent. These <br />cutbacks are summarized in Table 1 for the year 2025. <br /> <br /> Table 1 <br /> Project Water Summary for 2025 (af/yr) <br /> Description Normal Year Single Dry Year Multiple Dry Year <br /> Water Demand without Project 11,537 11,537 11,537 <br /> Water Supply .- 12,243 10,899 9,465 <br /> Water Shorta!:}e without Project 0 638 2,109 <br /> Water Shortaqe with 81 af6il'J:2ject 0 719 2,190 <br /> - <br /> Additional Cutback with Project 0% 0.74% 0.85% <br />I Source: Redwood City 2005 Urban Water Management Plan. <br /> <br />Page 2 of 10 <br />
