Call to Order City Administrator, Patrick Reilly welcomed those present and at 5:30 p.m., brought the meeting to order. He informed the Board the fifth member, Bill Scheiderich was unable to attend due to a prior commitment. 2. Approve February 23, 1994 regular meeting minutes Approve February 28, 1994 special meeting minutes Lynda Jenkins motioned to approve the meeting minutes as submitted and Peggy Manning seconded the motion. A voice vote was taken and the motion passed unanimously. 3. Water Supply Plan Update Patrick Reilly introduced Mr. Harold Murray, President of Murray, Smith and Associates, Inc. Mr. Murray introduced Chris Uber, Project Engineer with the firm and said they were both involved in the Phase 2 Regional Water Supply Plan so have good insight in the regions water supply. Mr. Murray explained to the Board Tigard's agreement with Murray, Smith and Associates provides for professional engineering services necessary to complete a water supply update plan. Mr. Murray said presently, Tigard contracts with the City of Lake Oswego and City of Portland for its water. Approximately 97% of Tigard's water now purchased is surplus from the City of Lake Oswego and the rate is established by the City Manager of Lake Oswego. Approximately 3% of Tigard's water is purchased from the City of Portland. The 25 year agreement with Portland was signed in 1983. After evaluating potential water supply sources including South Fork Water Board, City of Tualatin, the Joint Water Commission and a new Willamette River source, Mr. Murray indicated that at this point, the existing water providers capable of supplying water to Tigard include the Cities of Lake Oswego, Portland and the Tualatin Valley Water District. Each of these three water providers are currently evaluating improvements required to their systems in order to provide water to Tigard. Mr. Murray informed the Board that the completion of the project may be delayed as a result of not yet receiving the necessary information from these entities. INTERGOVERNMENTAL WATER BOARD MEETING - March 9, 1994 - Page 1 Mr. Murray reviewed briefly the means by which the cities of Lake Oswego and Portland supply water to Tigard. Portland water supply comes from a protected watershed, is chlorinated and not filtered and Lake Oswego provides a higher quality water as they have a water treatment plant - both meet federal standards. • Patrick Reilly asked Mr. Murray to clarify Lake Oswego's position regarding supply of water to Tigard. Mr. Murray responded that to the best of his knowledge, the City of Lake Oswego is faced with a big expense if they were to continue providing water to Tigard and they don't want to lose the revenue. He continued saying Tigard's share of the necessary improvements for Lake Oswego to continue providing water to the Tigard service area is estimated to be $24 million. • George Morgan asked Mr. Murray if a 90-120 day deadline for completion of the project is reasonable. Mr. Murray answered that an extension would be needed to complete the study. • Lynda Jenkins asked about the status of the long range population data. Mr. Murray indicated John Acker, City of Tigard Associate Planner, has provided his firm with these estimates. • Paul Hunt asked about the likelihood of getting water rights from the Willamette River. Mr. Murray explained that his firm just completed a water right analysis of the Willamette for the Regional Water Study and every indication says water rights will not be available. However, water is available from storage and the dams on the Willamette are owned by the Corp of Engineers. The Corp of Engineers do not have authorization to supply municipal and industrial water and it's a complicated process to get re-authorization. He further explained this process is very complicated as is the issue of water rights. • Peggy Manning asked Mr. Murray his opinion on Region 2040 and if he envisions one future regional water district. Mr. Murray responded that Metro's 2040 plan is strictly a concept of landuse and will be used to guide the region. Water supply to meet the future demands will be as a result of the Phase 2 study. A big push for everyone to consider combining efforts is evident however difficult due to the political entities involved, specifically those entities that own water rights. • Peggy Manning asked about Lake Oswego and negotiations for a minimum and maximum volume commitment. INTERGOVERNMENTAL WATER BOARD MEETING - March 9, 1994 - Page 2 Mr. Murray responded that he would recommend Tigard commit to a portion of Lake Oswego's debt and agree to pay off its share annually. He explained to the Board the term "cost of service'. In conversations between Lake Oswego and Murray, Smith & Associates, Lake Oswego has indicated they'd be able and willing to serve Tigard on the basis of cost of service. • George Morgan asked about the significance of the information needed to report to the City of Tigard and whether it might require a deferral as time gets closer for the forecast of regional information. He also asked if an interim short term contract for water would be preferred over the current arrangement and would it entail the involvement of other jurisdictions on a sub regional basis. Mr. Murray said Tigard currently has a backup source of water via a long term agreement with Portland. He explained the current contract with Portland specifically identifying the penalty terms. Using maps, Chris Uber presented to the Board an overview of Tigard's existing system. Mr. Uber said Tigard currently has in reservoirs 20.88 million gallons of water. In addition, he presented to the Board a water system hydraulic profile (attached) developed as part of the Regional Supply Plan, Phase 2. This schematic showed the regions major storage, transmission, pumping and supply facilities. He reviewed the process of getting Lake Oswego and Portland water to the Tigard service area and he talked about the advantages of gravity supply. • Lynda Jenkins asked Mr. Murray about aquifirs. Chris Uber and Harold Murray responded that the Regional Phase 2 Plan is looking at an alternative plan - A.S.R. (Aquifer Storage and Recovery). A.S.R. uses underground aquifirs as a storage vessel, pumping treated water down into the storage vessel during high flow periods and taking water out again during the summer. It is a new idea in this area and has been used in other parts of the country and is certainly a viable option. The whole subject of wells is being scrutinized - whether or not they are safe and can they be protected. All possible avenues will be looked at in the regional study before any decisions are made. After a brief discussion regarding a short term water source while investigating and negotiating for a long term water supply, Mr. Murray reminded those present that any existing, older system will be able to supply water less expensively than a new venture. Chris Uber talked about the daily capacity of Lake Oswego and the combined demand of Lake Oswego and Tigard. The current capacity of the treatment plant is 16.1 gallons per day and during the last hot day, the two cities combined demand was over 20 million gallons. As the populations increase, the improvements recommended in Lake Oswego's water master plan will double the capacity therefore, the $24 million cost. Lake Oswego has opted to hire an outside engineering consultant to complete an in-depth review of the 1988 Lake Oswego Water Master Plan recommendations for the supply of water to Tigard from Lake Oswego. Ultimately, the entire region will need to expand their facilities and water rates will increase. INTERGOVERNMENTAL WATER BOARD MEETING - March 9, 1994 - Page 3 • Patrick Reilly responded to a comment from Paul Hunt regarding the contract with Lake Oswego. He said the contract expired last year and Lake Oswego has agreed to continue to supply Tigard's service area with water to the end of this calendar year. There was discussion regarding the automatic renewal of the contract when it wasn't signed last year. Patrick Reilly informed the Board the contract has been assigned to. the City of Tigard and extended for one year under its current terms. After a brief discussion, the Board authorized Patrick Reilly to request an extension from the City Council, of the deadline for the update of the water supply plan. • George Morgan asked Mr. Murray about his firms role in the Regional Study. Mr. Murray responded Murray, Smith and Associates, Inc. is a subcontractor for Montgomery Watson responsible for the water treatment and transmission facilities. Murray, Smith and Associates, Inc. is doing the engineering work for transmission facilities interties, the regional system and reservoirs. Secondly,his firm provided the map detailing the regions infrastructure to the Study. Phil Smith, of Murray, Smith and Associates has just completed a water rights analysis on all the water sources. After further discussion with Mr. Murray about the regional study timelines and available options, the Board complimented Mr. Murray and Mr. Uber on their informative presentation. 4. Existing Long Term Capital Improvement Program This item will be put on the next meeting agenda. 5. There was a brief discussion regarding the agenda for the next meeting scheduled for March 23, 1994 and the meeting adjourned at 7:20 p.m. INTERGOVERNMENTAL WATER BOARD MEETING - March 9, 1994 - Page 4
