RECOMMENDATION: It is recommended that the City Council conduct a public hearing, respond to public comments, and adopt by Resolution No. 16-33 approving the City's 2015 Urban Water Management Plan. FISCAL IMPACT: There is no Fiscal Impact associated with this item. CORRELATION TO STRATEGIC PLAN: This item contributes to the fulfillment of the City's Strategic Plan Goal D: Strong Community and Regional Relationships. Specifically, by implementing Strategy 2, which is to work collaboratively with agencies within and outside of Tustin on issues of mutual interest and concern. Public Works June 7, 2016 Page 2 BACKGROUND AND DISCUSSION: The City provides water to a population of 68,088 throughout its 8.4 square mile service area. The City receives water from two main sources, the Lower Santa Ana River Groundwater basin, which is managed by the Orange County Water District (OCWD) and imported water from the Municipal Water District of Orange County (MWDOC) through East Orange County Water District (EOCWD). Groundwater is pumped from 8 untreated or "clear' groundwater wells that pump directly into the distribution system and two treatment facilities that treat groundwater from 5 additional wells. Currently, the total water demand for retail customers served by the City is approximately 11,115 acre- feet annually consisting of 2,890 acre-feet of imported water and 8,225 acre-feet of local groundwater. The Urban Water Management Planning Act of 1983 requires "every urban water. supplier providing water for municipal purposes to more than 3,000 customers or supplying more than 3,000 acre-feet of water annually' to prepare, adopt, and file an Urban Water Management Plan (UWMP) with the California Department of Water Resources (DWR) every five years, in years ending in five or zero. Adoption of the updated UWMP must be complete by July 1, 2016. The UWMP provides the DWR with information on the present and future water resources and demands and provides an assessment of the City's water resource needs. The UWMP is intended to serve as a general, flexible, and open-ended document that periodically can be updated to reflect changes in water supply trends, conservation and water use efficiency policies. Over the past year, staff has been working with Arcadis U.S., Inc. to develop the updated UWMP. The City's 2015 UWMP update has been prepared in compliance with the requirements of the Act, as amended, and revises the adopted 2010 UWMP. The 2015 UWMP, along with the City's Water Master Plan and other City planning documents, will be used by City staff to guide the City's water use and management efforts through the year 2020, when the UWMP is again required to be updated. The City's baseline water use is 189 gallons per capita per day (GPCD) which was obtained from the 10-year period July 1, 1995 to June 30, 2005. DWR has established four compliance options for urban retail water suppliers to choose from. Each supplier is required to adopt one of the four options to comply with SBx7-7 requirements. The four options include: Option 1: 80 percent of the base daily per capita (GPCD) water use Option 2: Performance standards-based water budget Option 3: 95 percent of a regional target set by the Department of Water Resources Option 4: Water savings estimates for replacement of plumbing fixtures Public Works June 7, 2016 Page 3 Option 1 was determined by MWDOC/Arcadis staff to provide the most flexibility for meeting both the 2015 and 2020 GPCD target, because it allows for either a retail agency to meet the conservation target or form a Regional Alliance to meet the conservation target. The City is a member of the Orange County 20x2020 Regional Alliance formed by MWDOC. This regional alliance consists of 29 retail agencies in Orange County. While each retail agency was required to choose a compliance option in 2010, DWR allows for the agency to change its compliance option in 2015. The City determined that utilizing Compliance Option 1 again for the 2015 UWMP would provide the most flexibility in meeting the established targets. Under Compliance Option 1, the simple 20% reduction from the baseline, the City's 2015 interim water use target is 170 GPCD and the 2020 final water use target is 151 GPCD. The Regional Alliance Weighted 2015 target is 175.9 GPCD and 2020 target is 156.4 GPCD. The Orange County 20x2020 Regional Alliance will achieve its water use reduction by building on the existing collaboration between Metropolitan Water District (Metropolitan), MWDOC and the local agencies in Orange County. MWDOC as a regional wholesale water provider implements many of the urban water conservation Best Management Practices (BMPs) on behalf of its member agencies. MWDOC's conservation measures are detailed in MWDOC's Regional Urban Water Management Plan (RUWMP), and Metropolitan's conservation measures detailed in their RUWMP. The UWMP calculates the City of Tustin's GPCD at 122. It is important to note that this was achieved during a period when drought restrictions were in place and customers were actively conserving water in anticipation of prolonged drought. In normal years, staff expects the GPCD to be consistent with the 2014 GPCD, which was 140. The attached 2015 UWMP has been made available to the public for review on the City's website, at the City Clerk's office, at the Public Works Department front counter, and at the City of Tustin Public Library. Staff is recommending that the City Council conduct a public hearing, respond to public comments, accept and adopt by resolution the City's 2015 Urban Water Management Plan. The last Tustin UWMP was adopted by the City Council in 2011. The 2015 UWMP updates are due to DWR by July 1, 2016.
