8A Page 9 Groundwater Supply Groundwater is not a source of potable water supply for Redwood City because of water quality, reliability, and long-term production capacity concerns. Local groundwater is currently used by a limited number of private well owners for domestic and irrigation uses. The City does not include groundwater as a source of supply in its 2005 UWMP. Summary of Current and Planned Water Supplies Table 2 identifies the existing and planned water supplies available for Redwood City from 2005 to 2030 in five-year increments. ---- Table 2 Current and Planned Water Supplies (af/yr) Water Supply Sources 2005 2010 2015 2020 2025 2030 .. - SFPUC Potable Water 12,768 12,096 12,544 12,768 12,880 12,992 Purchases (UBest EstimateU) Redwood City Recvcled Water 30 922 1,178 1 398 1,695 1,995 Transfers/Exchanqes in or out - 0 0 0 0 0 0 Desalination 0 0 0 0 0 0 Redwood City Groundwater* 0 0 0 0 0 0 TOTAL 12,798 13,018 13,722 14,166 14,575 14,987 *Defined as municipal potable source only.

THE PENINSULA PARK PROJECT AND ITS PROJECTED WATER DEMAND Project Description The Peninsula Park Project is a planned development located in Redwood City, at Bair Island Road/Ucelli Boulevard east of U.S. 101. It is a 33-acre property, which is currently used for an impound car storage lot, several paved parking lots, five partially occupied office buildings, a restaurant and other storage uses. it aiso includes a marina basin that ceased operations in 2001. The project as proposed would consist of 796 residential condominium units, 7,500 square feet of convenience retail and restaurant space, a 200-room hotel, 230,000 square feet of landscaping, which includes a community park, a marina with approximately 70 boat slips, parking areas, and pedestrian plazas and esplanades. Attachment 1 shows the conceptual site plan of the Project. Projected Water Demand The City estimated the future water demand of the Project as summarized in Table 3. The City bases its water demand projections on the adopted City Engineen'ng Standards for Water Demand Projection Criteria, known as "Attachment Qn, that is included as Attachment 2 to this document. In most cases, and in the aggregate. the City's future water use forecasts are higher than those made by the Project applicant's engineers. In brief, the projected net potable water demand for the Peninsula Park Project is 80.8 af/yr. The projected total water demand for the project is 186.4 af/yr. Of the 186.4 af/yr, 27.1 af/yr of the demand will be supplied by recycled water. In addition, 78.5 af/yr is allotted to the Project as a "credit" for historic water use at the Project site. An "acre foot" is equal to 325,851 gallons. One "acre foot"per year is equal to about 892.7 gallons per day. Page 6 of 10
