The base forecast in Chart One includes projected growth <br />information provided by the Community Development Services Department: <br />• By 2010 <br />0 1,390 acre -feet of demand for all new customers / growth <br />o Or the equivalent of 4,220 new housing units (could be a mix of commercial, housing <br />and /or public facilities) <br />• By 2020 <br />0 2,330 acre -feet of demand for all new customers / growth (cumulative) <br />o Or the equivalent of 7,115 new housing units (could be a mix of commercial, housing <br />and /or public facilities) <br />• All known large proposed development projects which are in various stages of review <br />• "Moderate" level of various small infill developments <br />• "Intensification of use" growth factor for existing commercial properties <br />The potential affects of two different levels of water conservation are shown — and the city's resulting gap in <br />water supply. If 2,000 acre -feet of new water supply in the form of recycled water is introduced, the chart <br />demonstrates that it is possible for Redwood City to bring total demand on Hatch Hetchy back to contractual <br />tpply assurance by 2010. However, as the "SFPUC Max Supply 10% Risk" line illustrates, 10% of the time <br />�dwood City is subject to less supply from the regional system due to droughts and /or shortages. This line <br />and its supply reliability implications should be regarded as a planning tool is addressing the question: How <br />much water reliability does Redwood City want to buy, and at what price ?" <br />16,000 <br />15,000- <br />R..
