Roll Call by City Clerk An Informal Informational Meeting ("Shirtsleeve" Session) of the Lodi City Council was held Tuesday, April 8, 2014, commencing at 7:00 a.m. Present: Council Member Johnson, Council Member Mounce, Council Member Nakanishi, and Mayor Pro Tempore Hansen Absent: Mayor Katzakian Also Present: Interim City Manager Schwabauer, Interim City Attorney Magdich, and City Clerk Johl-Olson B. Topic(s) B-1 Receive Information Regarding Surface Water Treatment Plant First Year Operation and the Drought Water Supply (PW) Deputy Public Works Director Larry Parlin provided a PowerPoint presentation regarding the surface water treatment plant operations and water supply during the drought. Specific topics of discussion included plant performance, project budget, major challenges, immediate challenges, current drought conditions, San Joaquin County data regarding water demand, groundwater conditions, Lodi groundwater supply, Mokelumne Watershed, drought impact on Lodi, and electric utility hydro impacts. In response to Council Member Mounce, Mr. Parlin confirmed that the water information management system has an annual licensing and maintenance fee of approximately $5,000 and is highly effective. In response to Mayor Pro Tempore Hansen, Mr. Parlin stated the security system, which was approved as a part of the plant permitting process, is operating and includes video and alarm systems. In response to Council Member Johnson, Mr. Parlin stated the person on standby resides within 20 minutes of the plant and the plant can be shut down remotely if need be with little impact due to the well back-up. In response to Mayor Pro Tempore Hansen, Mr. Parlin stated to date there have been no significant security issues and alarm testing is done on a regular basis. In response to Mayor Pro Tempore Hansen, Mr. Parlin stated the unused underground water supply remains in the ground for future withdrawal as needed. In response to Council Member Mounce, Mr. Parlin confirmed that groundwater is a regional matter, others outside of the City's jurisdiction can draw from the groundwater supply, during the summer the City may start to see outside jurisdictional withdrawal, and the State is going to start to regulate the groundwater withdrawal going into the future. In response to Mayor Pro Tempore Hansen, Mr. Parlin stated the new treatment plant in Stockton is also a membrane operating plant and is larger than Lodi's. In response to Council Member Nakanishi, Interim City Manager Steve Schwabauer stated that had the plant been privatized, the City Council could have required regular reports to the Council as a part of the contract. In response to Council Member Mounce, Mr. Parlin stated the complaints regarding the water quality have been largely resolved and they were primarily related to chlorination. In response to Council Member Johnson, Mr. Parlin stated that, with respect to the dam storage issue, he does not see the political philosophy changing in the near future because the interested parties cannot agree on the same set of facts. Mr. Parlin stated the future trend will likely be groundwater banking versus storage alternatives. In response to Mayor Pro Tempore Hansen, Mr. Parlin stated some cities, like Santa Cruz, may run out of water this summer and will start rationing any day while the forecast for other cities that were reportedly running out of water has improved. In response to Council Member Hansen, Mr. Parlin stated Southern California stopped increasing water import several years ago and the twin tunnels controversy also has the same challenges regarding interested parties agreeing on the same set of basic facts. In response to Council Member Mounce, Mr. Parlin confirmed that the Woodbridge Irrigation District (WID) water that is not utilized by the City rolls forward for future years and is not lost based on non -usage. In response to Council Member Johnson, Mr. Parlin confirmed that WID cut back water to both the City and the farmers and the long-term economic effects of the cutbacks remain unknown. In response to Mayor Pro Tempore Hansen, Mr. Parlin confirmed that the pre -1914 water rights can be over ridden by the State legislature in emergency conditions. A brief discussion ensued regarding types of water rights, including riparian and prescriptive, and the effects of the same. Council Member Nakanishi requested information regarding the water rights agreements that the City has with East Bay Municipal Utility District (EBMUD) and WID. In response to Council Member Hansen, Mr. Parlin stated currently the City uses approximately 15,000 acre feet annually, which is down a couple thousand acre feet from previous years. Mr. Parlin stated the City has a good supply of water for the next 3 to 5 years if not more and conservation efforts may become a mandate statewide in the near future in light of drought conditions. In response to Council Member Hansen, Mr. Parlin stated that each City department, including parks, will need to ensure that it is making appropriate conservation related changes in light of drought conditions and citizen concerns regarding the City's own efforts to conserve. A brief discussion ensued amongst Council Member Nakanishi and Council Member Johnson regarding the City's conservation efforts, including metering the parks and the effects of the same. In response to Council Member Hansen, Electric Utility Director Elizabeth Kirkley stated the City needs revenue to pay for power costs and the Energy Cost Adjustment (ECA) reacts on a monthly basis to ensure there is revenue for purchasing power supply. In response to Council Member Mounce, Ms. Kirkley confirmed that the electric rates may potentially rise in light of the drought creating deficiencies in the hydro portfolio. In response to Mayor Pro Tempore Hansen, Ms. Kirkley stated potential rate increases may be mitigated through the Lodi Energy Center, which can be optimized based on its technology to run on gas or power although market conditions remain a variable. In response to Council Member Johnson, Mr. Schwabauer and Ms. Kirkley confirmed that the City has a strategy to forward purchase power, which is administered through the Risk Oversight Committee, and the City is 70% to 90% bought out in power for the next several years. In response to Council Member Mounce, Ms. Kirkley stated the $1.4 million and $1.7 million figures are based on market conditions at a set time and are subject to variability. In response to Council Member Hansen, Ms. Kirkley stated staff is completing contract negotiations to meet requirements for AB 32 compliance by the 2020 deadline and she expects that the matter will come before the City Council for consideration in the next month or so. Council Member Mounce requested information regarding geysers and their affect on the City's portfolio. Council Member Nakanishi requested information regarding the average use of hydro in portfolios of other agencies including PG&E and SMUD. C. Comments by Public on Non-Aaenda Items None. D.
