HARBOR BLVD. MIXED USE TRANSIT CORRIDOR PLAN FINAL FIR CITY OF SANTA ANA 5. Environmental Analysis UTILITIES AND SERVICE SYSTEMS Pipes that distribute water to the project area are cast iron pipe, clay pipe, ductile iron pipe, cement mortar lined and coated steel pipe or asbestos - cement and range in size from 6- inches to 16- inches. Existing water pressures vacv between 70 to 85 psi. Regulatory Setting State Un5an Water Management Planning Act The Urban Water Management Planning Act of 1983, California Water Code Sections 10610 et seq., requires preparation of a plan that: • Plans for water supply and assesses reliability of each source of water, over a 20 year period, in five -year increments. • Identifies and quantifies adequate water supplies, including recycled water, for existing and future demands, in normal, single -dry, and multiple -dry years. • Implements conservation and the efficient use of urban water supplies. Significant new requirements for quantified demand reductions have been added by the Water Conservation Act of 2009 (Senate Bill 7 of Special Extended Session 7 (SBX7 -7)), which amends the act and adds new water conservation provisions to the Water Code. 20x2020 WaterConsermizon Plan The 20x2020 Water Conservation Plan, issued by the Department of Water Resources (DWR) in 2010 pursuant to the Water Conservation Act of 2009 (SBX7 -7), established a water conservation target of 20 percent reduction in water use by 2020 compared to 2005 baseline use. Senate Bills 610 and 221 To assist water suppliers, cities, and counties in integrated water and land use planning, the state passed Senate Bill (SB) 610 (Chapter 643, Statutes of 2001) and SB 221 (Chapter 642, Statutes of 2001), effective January 1, 2002. SB 610 and SB 221 improve the link between information of water supply availability and certain land use decisions made by cities and counties. SB 610 and SB 221 are companion measures that promote more collaborative planning between local water suppliers and cities and counties. Both statutes require detailed information regarding water availability to be provided to city and county decision makers prior to approval of specified large development projects. This detailed information must be included in the administrative record as the evidentiary basis for an approval action by the city or county on such projects. The statutes recognize local control and decision making regarding the availability of water for projects and the approval of projects. Under SB 610, water supply assessments (WSA) must be furnished to local governments for inclusion in any environmental documentation for certain projects subject to CEQA, as defined in Water Code Section 10912[a]. Under SB 221, approval by a city or county of certain residential subdivisions requires an affirmative verification of sufficient water supply. SB 221 is intended as a fail -safe mechanism to ensure that collaboration on finding the needed water supplies to serve a new large subdivision occurs before construction begins. Page 5.144 PlaceWorkr
