HARBOR BLVD. MIXED USE TRANSIT CORRIDOR PLAN FINAL FIR CITY OF SANTA ANA 5. Environmental Analysis UTILITIES AND SERVICE SYSTEM The Urban Water Management Planning Act states that every urban water supplier that provides water to 3,000 or more customers or provides over 3,000 acre -feet (af) of water annually, should make every effort to ensure the appropriate level of reliability in its water service to meet the needs of its various categories of customers during normal, dry, and multiple dry years. Both SB 610 and SB 221 identify the urban water management plan (UWMP) as a planning document that can be used by a water supplier to meet the standards in both statutes. Thorough and complete UWMPs are foundations for water suppliers to fulfill the specific requirements of these two statutes, and they are important source documents for cities and counties as they update their General Plans. Conversely, General Plans are source documents as water suppliers update the UWMPs. These planning documents are linked, and their accuracy and usefulness are interdependent. (CDWR 2003) City of Santa Ana Required permanent water conservation measures, and temporary water conservation measures in the event of a water shortage, are set forth in Sections 39 -105 et seq. of the City's Municipal Code. Landscape water use standards are set forth in Section 41 -1503 of the Municipal Code. Water Efficiency Standards There are many water efficiency strategies that have been implemented in the City of Santa Ana that would also reduce potable water demands for the Harbor Corridor Plan. A Water Conservation Ordinance was adopted by the City Council in 2009. The City also participates in MWDOC's Water Use Efficiency Program and is a signatory in the California Urban Water Conservation Council. The City has implemented the following demand management measures (DMMs): • Water survey programs for single -family residential and multi -family residential customers • Residential plumbing retrofit (low flow showerheads and ultra low flow toilet rebate program) • System water audits, leak detection and repair • Metering with commodity rates • Large landscape conservation program and incentives • High- efficiency washing machine rebate programs • Public information programs • School education programs • Conservation programs for commercial, industrial, and institutional accounts • Conservation pricing for water bills • Appointment of a water conservation coordinator • Water waste prohibition (in accordance with the Water Conservation Ordinance) October 2014 Page 5.14 -7
