2015 URBAN WATER MANAGEMENT PLAN Kffa 2.1 Overview Since the last UWMP update, southern California's urban water demand has been largely shaped by the efforts to comply with SBx7 -7. This law requires all California retail urban water suppliers serving more than 3,000 acre -feet per year (AFY) or 3,000 service connections to achieve a 20 percent water demand reduction (from a historical baseline) by 2020. The City has been actively engaged in efforts to reduce water use in its service area to meet the 2015 interim 10 percent reduction and the 2020 final water use target. Meeting this target is critical to ensure the City's eligibility to receive future state water grants and loans. In April 2015 Governor Brown issued an Emergency Drought Mandate as a result of one of the most severe droughts in California's history, requiring a collective reduction in statewide urban water use of 25 percent by February 2016, with each agency in the state given a specific reduction target by DWR. In response to the Governor's mandate, the City is carrying, out more aggressive conservation efforts. It is also implementing higher (more restrictive) stages of its water conservation ordinance in order to achieve its demand reduction target of 12 percent set for the City itself and the Regional Alliance of all participating MWDOC utility agencies (discussed later in Section 2.5). In addition to local water conservation ordinances, the City partnered with Metropolitan on educational programs, indoor retrofits and training. The City has implemented turf removal, an art contest, pole banners, lawn signs, and neighborhood association meetings to promote water conservation, as detailed in Section 4. These efforts have been part of statewide water conservation ordinances that require watering landscape watering, serving water in restaurants and bars, and reducing the amount of laundry cleaned by hotels. Further discussion on the City's water conservation ordinance is covered in Section 5 Water Supplies Contingency Plan. This section analyzes the City's current water demands by customer type, factors that influence those demands, and projections of future water demands for the next 20 years. In addition, to satisfy SBx7 -7 requirements, this section provides details of the City's SBx7 -7 compliance method selection, baseline water use calculation, and 2015 and 2020 water use targets. 2,2 Factors Affecting Demand Water demands within the City's service area are dependent on many factors such as local climate conditions and the evolving hydrology of the region, demographics, land use characteristics, and economics. In addition to local factors, southern California's imported water sources are also experiencing drought conditions that impact availability of current and future water supplies. 75E -21 arcadis.com 2 -1
