Chair — Commissioner Bill Scheiderich Vice-Chair — Commissioner Patrick Carroll Agenda Items #4 and #5 were reversed: 5. Committee for Citizen Involvement Update— Duane Roberts Duane Roberts, Long Range Planning, was representing the Committee for Citizen Involvement (CCI). City Council has suggested that all active boards and committees should appoint a representative to serve on that committee, which presently is comprised of four members. The committee meets every two months and has focused on establishing broad public involvement. The Council wants neighborhood structures established, who would then be able to have representatives. Commissioner Bill Scheiderich volunteered to represent the IWB at the CCI meetings. 4. Regional Water Supply Plan Update— Dennis Koellermeier & Lorna Stickel Mr. Koellermeier introduced Lorna Stickel, Water Resources Manager with the City of Portland and staff member to the Regional Water Consortium. Lorna gave a PowerPoint presentation as update to the Regional Water Supply Plan (RWSP) and IGA changes. Intergovernmental Water Board March 9, 2005 DRAFT 1 As a brief history: • Consortium established in 1997. • First regional water supply plan adopted in 1996. • Columbia Water Conservation added. Emergency Management plans. • IGA states that plan will be updated every five years. • Update process began in 2001, financed by a two year special assessment. • Project carried over into third year. • Board presented with key findings in June 2004. • Draft document presented in September 2004 and approved in December 2004. • Contracts with several consulting firms: EES for source review, PMCL for conservation program analysis, Gary Fiske for integration Updated plan consists of: 1- Introduction —sets frame for update process, documents change in emphasis for the planning role of the RWSP and Consortium 2- Water demand forecasts—details of methodology, charts for each member with peak day, season and average demands annually, forecasts show increases, per capita decreases 3- Conservation — programs, spreadsheet model evaluating program costs and savings, sets of programs selected by each provider to meet their unique needs, overall savings estimated to be 19.3 mgd for peak season by 2025 4- Source Options — revised the base case and committed near term sources based on provider information and master plans, evaluated source options for the update to include Bull Run, Clackamas, Columbia, Trask/Tualatin, Willamette Rivers and ASR, wellfields and local smaller sources, updated hydrology, water rights, costs, and ratings for sources, prepared new transmission linkage 5- Modeling — described confluence model methodology, listed base case supplies, conservation program savings, and the five strategies evaluation: base case, Hagg Lake raise, Clackamas River, Bull Run Source development emphasis, limited expansion of local projects, results displayed for ability to meet future demands for region 6- Revised RWSP Strategies — contains revised set of policy objectives, integrates the source water protection and transmission/storage strategies adopted by the board, conservation strategy, non-potable water sources, source options listed in detail as new potential sources, emergency preparedness role, consortium planning functions to support local decision making, role of the consortium and Metro, changing the update period to 5-10 years as needed in proposed IGA amendments. The report also reviewed the Willamette River as an option. Process for IGA Amendments • board recommends approval of amendments • copies sent to all entities • response needed by June 2005 Consortium budget is adopted annually. Tigard's dues are $21,000 and will increase $500+. Intergovernmental Water Board March 9,2005 DRAFT 2 Mr. Koellermeier did not bring a copy of IGA, but will send it in the next packet to IWB members for review and to make recommendations at the next meeting. 5. Committee for Citizen Involvement Update— Duane Roberts (Covered above) 6. Long Term Water Supply Update— Dennis Koellermeier Mr. Koellermeier stated that the media has been going wild with reports of drought possibilities. Tigard does have a summer supply plan, but we are unable to get viable weather information for more than two months in the future. Tigard continues to try to get others to understand how the water system works in the area. Spring rains feed the water system. The Bull Run is at its usual level now of 92% full. Expectations are that we will be getting adequate spring rains to keep the water systems in good condition. Bull Run System — May to mid-July they use impounded water to meet the demand, called a draw down period. Three scenarios are plotted by Portland, which triggers when other sources will be drawn on for use. Portland has been convinced that doing a blend of waters earlier than usual is better. Well water is harder, but potable in quality. Hagg Lake and Barney Reservoir— Hagg Lake is down, Barney Reservoir is on schedule. Tigard got 4 mgd from the JWC last year. Plans for this year — look at our historical usage. To avoid minimum purchase penalties with Portland, Tigard will take water from them first and lease water from JWC members. Because of current weather conditions, we are securing more than 100% of the water we need and planning for 102-114% of what we need. Tigard is adding Lake Oswego to the water supply source, which is different than the recent past. They have surplus water and it will cost us about the same as JWC water. We will receive Lake Oswego water supply for next year at 2.5 mgd. Mr. Koellermeier said he was fairly sure all our bases were covered for summer weather peaking issues. The last time we had a drought we made great conservation steps. Many people are talking about the water situation now and will hopefully be cautious with water usage early on. If the entire region gets into a supply problem, all the entities work together to resolve the shortage. (No outside watering, no car washing, etc., would be steps taken first.) Educating the public brings the best results for the money. 7. Informational Items— Dennis Koellermeier 8. Public Comments - NONE 9.

There will not be a regular IWB meeting during April, however the board will meet jointly with the Tigard City Council. The board decided they would make a decision on the IGA in May. 11.

RECITALS: WHEREAS, the Participants previously entered into a Regional Water Providers Consortium Agreement in 1996 and 1997; and WHEREAS, operating under the original agreement has led the Participants to determine that certain changes should be made to create a more effective document and one that better reflects the Participants' current and future method of operation; and WHEREAS, The Consortium Board adopted a new 5-Year Strategic Plan in June of 2004 that directed an examination of the Consortium IGA and Bylaws, and WHEREAS, the primary current activities of the Consortium are largely directed at activities that provide immediate benefit based on the current size of the member entities, a revised dues structure was felt necessary; NOW, THEREFORE, the Participants agree to amend the Agreement as follows and that any part of the Agreement not amended shall remain as originally written: Section 1. Definitions „Censertnum TeEhniEal "Plan" - That document dated October 1996, entitled Regional Water Supply Plan for the Portland Metropolitan Area, and all subsequent amendments thereto, referred to herein as the "Plan." Section 2. Purposes The general purposes of the Consortium are as follows: A. of Participants implementing the To provide a collaborative clearinghouse function for water supply planning and development that fosters regional coordination. B. To serve as the central custodian for Plan documents including computer models and other local decision support functions. D. To provide a forum for the study and discussion of water supply issues of mutual interest to the Participants and Eeee collate the responses of Participants to such issues. E. To provide a forum for review and discussion of water resource related issues , regaFdiRg 0ssues whoch ,.euld be ,.ens4dered to relat-e that may relate to application of the statewide land use goals, comprehensive plans, regional plans or land use regulations. F.

G. To conduct regional conservation program s H. To facilitate emergency_preparedness for water suppliers in the region Section 3. Endorsement of Regional Water Supply Plan B. The Participants have endorsed the Plan in erdeF te previde guidanee feF supply ceeperatien. Endorsement of the Regional Water Supply Plan (RWSP) and coordination and collaboration between the Consortium members that avoids duplicative efforts and cost are part of the ongoing commitment of the Participants jointly te meet the wateF supply needs of the reglen to jointly study and create a Regional Water Supply Plan. The RWSP is intended to be a clearing house for local water supply planning and provides support for individual water supply planning and decision making. Section 7 Dues I. The dues of each water provider participant shall be determined annually as follows: 1. Total annual dues for all members shall be set to equal the annual budget for the Consortium, not counting budget items to be funded by fewer than all the Participants as provided in Section 8. C., and taking into account any grants or non-dues monies available to fund the annual budget. 2. The total annual dues of Participants that are not water providers shall then be subtracted from the total annual dues- based budget, described in subsection 7.13.1. above, leaving a budget amount to be funded by provider dues. Dues shall be set so that the dues of each water provider reflects its proportional share of that sum based on the following formula: (a) 275% 50 % of the total provider shall be allocated proportionally based on the individual provider's proportional share of the total number of all Participants' retail customer accounts for the prior year. (b) 25% 50% of the total provider dues shall be allocated proportionately based on the individual providers' proportional share of the total average daily retail water use (in millions of gallons per day) in the prior year of all Participants. (1&) 50% ef the tetal pFev*deF dues shall be alleEated prepertionally based en the individual pFevider's average daily supflffler peak seasen use (on milliens. ;neremental e shall be based on the frem the first te the last year of the regienal wate recent Fegienal fereEast approved as a Plan Participant's governing beards, eemmissiens, eF ce s (c) The change made to the Consortium's formula in FY 2004/5 shall be phased in at 50% in FY 2005/6 and at 100% in FY 2006/7.

Unless otherwise noted, all of the results are for finished water. The results for the City of Portland's Bull Run and Columbia South Shore system have been verified by Yone Aggai, P.E., of the Portland Water Bureau. The results for the JWC have been submitted by JWC staff. The data for the Willamette River Water Treatment Plant at Wilsonville is the result of the testing program that TVWD undertook and supplemented with data supplied by City of Wilsonville. The additional Willamette data provide by the City of Wilsonville was included at the request of the Portland Water Bureau. Dean Fritzke, TVWD Water Quality Coordinator together with other TV" staff prepared this table and reviewed all the results. We believe that this represents an accurate comparison between the three sources.
