INTERGOVERNMENTAL WATER BOARD MEETING MINUTES March 8, 1995 BOARD MEMBERS PRESENT: Bill Scheiderich, Paul Hunt, Violet Yager, and Beverly Froude STAFF PRESENT: Ed Wegner, Randy Volk, Mike Miller, Mary Gruss, and Kathy Kaatz VISITORS PRESENT: Jack Polans 1. Call to Order The meeting of the Intergovernmental Water Board was called to order at 5:30 p.m. 2. Roll Call and Introductions Roll call was taken and all members were present with the exception of Peggy Manning. 3. Visitor's Comments Mr. Jack Polans quoted from the January 24, 1995 letter of intent from former Commission Morgan and stated that he wanted to discuss the revenue analysis but would wait until another time to discuss. Mr. Polans referred to the January 12, 1995 agenda item of the City of Tigard 3.2 (Water Rate Analysis) and stated that he was concerned about the proper consultant being hired. Mr. Polans also discussed the January 11, 1995 meeting agenda of the IWB and the issue of negotiations with Lake Oswego. Chair Scheiderich stated that Mr. Polans would need to address any further issues at another time since visitor's comments are limited to five minutes. Mr. Polans stated that he would write a letter to finish addressing these issues. Mr. Polans questioned whether the IWB Board is an independent advisory board to the City of Tigard? Mr. Polans questioned whether the board made its own observations of the facts presented? Chair Scheiderich stated that observations and recommendations was the appropriate term. Mr. Polans stated that he feels uncomfortable with the amount of influence from the staff of the City of Tigard. Chair Scheiderich stated that there is nothing inappropriate with the City of Tigard being represented on this Board nor with it supplying the staff. He also stated that Council President Hunt does the Board a service by being on the Board and listening to the concerns of the smaller cities who do not have control of the assets. Chair Scheiderich stated as to updates on the status of negotiations there would be no reason to lack confidence. Commissioner Froude stated that at both the meetings of the TWD and the IWB there is always a Director's report which is stated as well as written in the minutes on the interim and long term water supply. Commissioner Yager stated that negotiations are going on in executive sessions with Lake Oswego and Tigard and that is confidential. She also stated that there are regularly scheduled meetings as well as a time line. She stated that reference has been made to communications although the content has not been discussed. Ms. Yager questioned whether there would be a progress report to be given at this time? Chair Scheiderich stated that we are given verbal reports at every meeting. There may be separate progress reports being given to the Tigard City Council but he doubts they would be any different than is presented here. Mr. Wegner stated that negotiations have been going on for approximately five months and within this time period both cities have had major elections, which has involved getting new members of councils brought up to date. Early in negotiations it was decided that detailed information would be held in executive sessions between the Tigard City Council and the Lake Oswego City Council. Mr. Monahan met with the IWB back in December in executive session and brought the Board members up to date on the status of negotiations. The new Mayor for the City of Tigard and the City Manager have been meeting with the Mayor and the City Manager of Lake Oswego in working out some of the concerns. As this progresses, the Board will be kept up to date whether it be in an open meeting or an executive session. Commissioner Hunt stated that in order to run meeting efficiently, he felt that visitors comments need to be limited to a five minute presentation. 4. Approval of Minutes Mr. Hunt made a motion to approve the minutes of the February 22, 1995 meeting minutes as written. The motion was seconded by Commissioner Froude. 5. Rules, Rates and Regulations - Randy Volk Mr. Volk stated that a draft was presented to the Board members on the Rules, Rates and Regulations which were adopted by the 190 agreement last year, Exhibit A, Chapter 12.10 (City Code). At the time of the IGA, the City of Tigard's attorney looked over those Rules, Rates and Regulations and made some changes which were adopted in the form that was presented tonight. The Accounting Department who Intergovernmental Water Board, 3-8-95 Page 2 now takes care of the billing for the Water Department had made some changes and also has made some slight changes in the operations which necessitates some rewording. The old Rules, Rates and Regulations as they were adopted have been crossed out and in bold print are the new recommendations. Exhibit B which was approved but was not supplied tonight are the current rates. Commissioner Hunt questioned item 12.10.070 - Credit for Water Leaks and whether it should state that amounts over $165.00 can be appealed to the IWB? Randy Volk stated that this may be covered in another section (Grievances, Power to Grant Variances) but, if it is a concern it can be amended. Mr. Hunt questioned (12.10.110 - Cross Connection Control Program) whether irrigation backflows that are required to be inspected once per year, are being enforced? Mr. Hunt concern is that we are requiring something that we are currently not enforcing. Mr. Hunt also questioned whether the Water Department could make a better deal on supplying backflow devices for the public? Randy Volk stated that the Backflow Program which is currently in operation does deal with commercial and fire lines, but the Water Department is beginning to make note of the residential use of irrigation systems, so as to enforce these. Mr. Volk also stated that there are only a few double check valves and RP's that are currently approved by the State. Mr. Hunt stated that the Rules, Rates and Regulations states that the meters are read once every eight weeks. Mr. Hunt questioned whether this should state that the meters are read at Department discretion? Commissioner Froude stated that she felt that once every eight weeks is very specific. Mr. Hunt stated that there has been discussion to the reading time being changed and this would allow a little more flexibility. Mr. Wegner questioned whether this could be stated as meters will be read based upon the policies set by the IWB and the Tigard City Council. This would allow the flexibility if we were to change the reading times. Commissioner Froude discussed who has access to these polices and the fact that they are available to the general public, she felt they should be specific. Mr. Wegner stated that these policies can be amended at any time by Resolution by the IWB and/or the Tigard City Council. Mr. Hunt questioned the Water Main Extensions (12.10.170) being in conflict with City Reimbursements Districts. Mr. Wegner stated that he is checking with the City Attorney's office and will let the Board know. Intergovernmental Water Board, 3-8-95 Page 3 Mr. Hunt stated that the City of Tigard has a Reimbursement District policy which they are in the process of re-writing. This policy states that any services that will service others can form a District and collect back from them. Randy Volk stated that in the memo from Ed Wegner it stated that the Board would briefly look at this document and next month will discuss further. Randy Volk stated that he would provide Exhibit B to the Board. Mr. Volk also thanked Mike Miller and Mary Gruss for assisting with the updating on this document. Mr. Wegner stated that if the Board members had any questions or concerns to let us know and we will have those incorporated into draft number two for the next meeting. 6. 1995/96 Budget Review - Ed Wegner With the Board's approval the Request For Proposal for Water Rate Study was discussed next. Mr. Wegner stated that he has already had some concerns voiced to him as follows: a. #7 and #5 should be that they address the proposed Capital Improvement Projects not identify them. b. Page 11, #2 should read, the System Development Charges for the City of Tigard by Economic Engineering Services. C. Page 13, one typographical mistakes (structures). d. Page 14, two typographical mistakes (payment will be in lump sum, and authorized by. We will be forwarding this draft with the above corrections and any others necessary by the Board to the Tigard City Council for adoption. Mr. Wegner stated that the consensus of the Water Department and the Finance Department was that this would be completed by June 30, 1995, although it now appears it will be into July or August. Commissioner Froude questioned whether there is something in this document which discusses overruns or the consultant not staying within their budget? Mr. Wegner stated that the Contract will state that it will be for a lump sum. Mr. Hunt questioned the time frame for preparation of bid and whether it allowed for sufficient time. Mary Gruss stated that these dates can be adjusted. Chair Scheiderich questioned whether this RFP would contain a scoring matrix or a list of criteria on how they are to be evaluated? Mr. Scheiderich stated that this should be placed in the RFP and state that these proposals will be evaluated on the basis of following.... Intergovernmental Water Board, 3-8-95 Page 4 6. 1995/96 Budget Review - Ed Wegner Mr. Wegner stated that he had presented to the Board a draft of the Water Department budget overview requests. Mr. Wegner stated that at the April meeting either Bill Monahan or himself will present to the Board a more detailed budget that will be presented to the Budget Committee and the Tigard City Council. Last March if referred back to the minutes of the IWB, it was discussed that the IWB has the right to submit changes directly to the Budget Committee. Mr. Wegner stated that we would be going through the line items and to discuss what items are included in that line item and why the changes in percentages from the last budget. Mr. Wegner stated that the r500 account lines items deal with staff and are completed by the Finance Department with the exception of #505 and #520 and the 600 account line items deal with operations. Mr. Hunt questioned why line item 551 .000 went down 74% (Workers Compensation)? Mr. Wegner stated that this would need to be addressed by the Finance Department. Randy Volk discussed line item: 505.000. He stated that last year he had six part time help and four of those worked directly with the Water Department and two were shifted to work on the Grounds Crew which was to maintain the reservoir grounds. 520.000 Overtime covers both the call out and the on call person for the weekend as well as any additional overtime necessary. Mike Miller discussed line item: 600.000 Cost of Water. The reason for rising 27% are the increase in rates from the City of Portland which increased 126% from last year. Mr. Miller stated that Lake Oswego and Tualatin Valley Water prices are estimated. Mr. Hunt questioned what else goes into the calculation of the 27% increase? Mike Miller stated that he also calculated an increase in the Lake Oswego rates, these rates have not been raised in the last two years and Tualatin Valley charges were unsure so he calculated what they currently pay City of Portland and added some overhead costs to that. Mr. Miller also stated that increased consumption is also included in these calculations. Mr. Miller stated that we bought less than $62,000 water from Portland last year and then this year to jump to $142,000 is a big increase. Intergovernmental Water Board, 3-8-95 Page 5 Ed Wegner discussed line item: 601.000 Professional Services. This is where consultants are paid from. Last November the City of Tigard entered into an Agreement with Murray Smith and Associates (four year contract at $25,000 per year) has increased this account as wells as a seismic and stress analysis on the steel tanks. Mr. Wegner stated that this week while cleaning the 10mg site, it was noticed that there is a separation along the outside wall and there is a structural engineer coming in Friday to determine the cause. This line item expense may be necessary. 602.000 Contractual Services.. This line item is up considerably since this year we have combined budgets to better serve the City's accounting system. This line items will include janitorial service, SCADA system programming, heating and air conditioning service, answering service for emergency calls. Mr. Wegner stated that if a responsibility is transferred to another division, the money to provide for these services will continue to come from that department budgets. Commissioner Froude questioned the use of the building for night meetings, weekend use, and the homeless shelter? Mr. Wegner stated that the Water budget has always paid for that. He also stated that the Finance Department will be suppling a matrix that outlines these charges which are divided among the different divisions within the City. Mr. Wegner also stated the 1 % of sales which also goes to King City, Durham and the Tigard Water District comes out of the Contractual Services line item. Bill Scheiderich questioned line item 704.000 - Office Furniture and Equipment. Mike Miller stated that the Water Division is budgeting for a new software program from Hansen Information and Technology. This program is currently being used for maintenance purposes within Maintenance Services in Sanitary, Storm, and Streets. This new software program will enable the Water Division to track maintenance of valves, pumps and pumping facilities, timing of blowing off dead end lines, fire hydrant repairs and maintenance. We are currently doing all these tasks manually which is very time consuming. He also stated that this line items includes budgeting for AutoCad software and workstation to bring the drafting capabilities of the Water Division to the same level as the City's Engineering staff. Mr. Hunt wanted to clarify whether this was an item that was used by various departments or the Water Division? Mike Miller stated that this was a large packet and this portion was strictly for the Water Division. Intergovernmental Water Board, 3-8-95 Page 6 Mr. Scheiderich questioned line item 706.000 - Operation Equipment. Randy Volk stated that this included the purchase of a $62,000 backhoe, but with trade-ins hope to have down to $48,000. Another item included is a meter reading van for $17,500, a 20 ton utility trailer, and shoring shield for $3,750. The trailer the Water Division has currently is inoperable. This trailer,purchase will be shared by other divisions (2/5 Water, 2/5 Wastewater and Storm, 1/5 Street) as well as the shoring shield. The Water Division is also sharing in the cost of a concrete cutter that the Wastewater Division is purchasing. This line item includes a chlorination station which will add chlorine to the water as needed prior to pumping up to Bull Mountain, sample stations for water quality, SCADA upgrade to upgrade system and also a purchase of two way radios which will replace existing incompatible radios. Paul Hunt questioned if there were two meter reading vehicles? Randy Volk stated that we currently have two meter reading vehicles that were purchased from TVWD and were used before that by the postal Service. Bill Scheiderich questioned the last time contracting out the meter reading services was? Mr. Volk stated that this is discussed on a regular basis. Currently the meter reading program is coming along fine, but when additional purchases are requested the need to look at contracting those services out needs to be addressed. Mr. Scheiderich questioned whether Tigard is a party to the sharing of equipment within the area? Mr. Wegner stated that the City is involved in this, but a backhoe is seldom available through other agencies. Ms. Yager questioned the software purchase and how much projected savings there will be? Mr. Wegner stated that all utilities within the infrastructure will be computerized (all manholes, valves,, meters,fire hydrants). This software will have the ability to generate workorders, monthly reports, accomplishments and will track problem areas within the City limits. Hopefully within the first four months we will be able to generate reports and within one year to eighteen months will have everything City wide on this system. Mr. Hunt questioned the vehicle purchases being contingent upon the meters being read in house. Mr. Wegner stated that a determination will be made and will be brought to the Board and the Tigard City Council by January 1, 1996 if this will be done in house or contracted out, if contracted out the vehicle will not be purchased. Mr. Wegner questioned whether the Board would like to have a individual copy of the budget pages? The Board stated that they would prefer to have a written summary as well as answers provided to the questions that were not answered at this meeting. Mr. Scheiderich stated that if a written presentation is being made to the Budget Committee he would like the Board to also receive a copy of that. Intergovernmental Water Board, 3-8-95 Page 7 Mr. Polans questioned if this was the end of the budget discussion? Mr. Wegner stated that he still had two more pages to discuss. Mr. Wegner stated that another page submitted included all the Water Division employees paid through the Water fund including all benefits. Also distributed is the program summary which states last year goals, projected goals and objectives for 1995/96 and performance measures. Mr. Polans again questioned if this ended the budget discussion? Chair Scheiderich stated that this ended the preliminary review of the budget for this evening. Mr. Polans asked if he could ask a question of'the Board. The Board declined answering any .more questions at this point, but stated that Mr. Polans could direct those questions to Mr. Wegner after the meeting, if time allowed. 7. Director's Report - Ed Wegner Mr. Wegner requested the Board to hold a second meeting this month on March 22, 1995. Mr. Wegner stated that by the first of next week, we will have a draft agreement of an IGA between City of Tigard and Tualatin Valley Water District to buy surplus water from them for the interim supply. We will also have a cost estimate to connect to Tualatin Valley at the Baylor Street location, and cost estimates for improving to well #2 and #3. We would like to bring these to the Board on March 22nd and on March 28th take these to the Tigard City Council to begin the process and have Baylor Street and the wells on line by July 1, 1995. Mr. Hunt questioned if haven't reached an agreement with TVWD how can we set an interim contract if we don't know what the interim will be (3 months to 13 years)? Mr. Wegner stated that if long term contract with Lake Oswego is negotiated it will take from 3-5 years. The interim IGA with TVWD states that we are looking for a long term source and when that comes on board we will have the ability to remove from the contract. Chair Scheiderich pooled the Board in regards to a March 22nd meeting? The Board was in agreement and the Chair questioned whether Mr. Wegner would notify Ms. Manning? Long Term Water. Mr. Wegner stated that the Mayors and City Mangers from City of Tigard and Lake Oswego have met twice and they are both reporting back to their respective City Councils Tuesday and hopefully will have the five major areas of concern resolved. Mr. Wegner stated that at the meeting on March 22, 1995 or the April 8, 1995 meeting he feels confident that Mr. Monahan will address the Board and discuss the majority of the contract. Chair Scheiderich stated that he would prefer that on one of those dates, he would like to have something in writing or presented in person, what has been agreed upon. Intergovernmental Water Board, 3-8-95 Page 8 Mr. Hunt stated that if Mr. Monahan does not feel comfortable discussing in a public meeting than it should be addressed in executive session. Mr. Wegner stated that even though the contract will be between the City of Tigard and the City of Lake Oswego, the recitals state that the City of Tigard is representing Durham, King City, and the unincorporated area. Mr. Wegner stated that there is no new movement on the Willamette River Study. Mr. Scheiderich questioned whether there would be any new movement until the State of Oregon resolves Pacific Power and Lights claims to twenty times the volume going over the Willamette Falls? Mr. Wegner stated that as soon as the regional study is complete the lower part will move along according to Phil Smith (MSA) since this is the area not affected by PGE claims. This study is tentatively due to be completed by November. There should be a preliminary report completed in July and a final report adoption by each entity in November. Mr. Wegner also provided the Board with a copy of the last minutes from the Regional Water Supply Plan Participants Meeting held February 21, 1995. The City of Tigard has instructed the City Manager and the Director to make application to the State of Oregon for water rights on the Willamette River. The locations of these will be in the area that Tualatin Valley and Wilsonville have water rights which is not in the area of the PGE claims. Mr. Wegner discussed the results of the testing on the 10mg pumping sites which stated that we would have the ability to draw down from about 16.5 feet to 6 feet which could give us two million gallons of water more than last year. Mr. Wegner stated that Lorry Christian who had been working in the Human Resource Department has resigned and taken a position in the private sector. This will enable the Water Division to utilize that position within the Water Division as a Utility Worker. Mr. Wegner had also distributed a copy of the water conservation program through Northwest Natural Gas and stated that the Water Division was very successful with 4,102 participants with a cost of a little over $6,000. Mr. Wegner also stated that we are putting articles in the Cityscape this month which will be distributed to Durham and King City. At the request of the TWD we will be checking into doing mail inserts into all water bills or at the cost involved in doing a mailing to involve those occupants to the unincorporated area. Mr. Wegner stated that Murray Smith and Associates would be beginning the survey of the land for the Menlor Reservoir site. This report should be provided within the next six weeks. Intergovernmental Water Board, 3-5-95 Page 9 Mr. Wegner also stated that as soon as the monthly report was available it would be mailed out to the Board. Chair Scheiderich questioned whether the City was pursuing any other water conservation efforts? Mr. Wegner stated that the City has checked into the toilet bags and double levers. We will be offering this Spring some seminars on irrigation systems by the landscaping crew and the backflow crew. Commissioner Froude questioned whether there would be any attempt to pursue commercial customers lack of conservation measures. Mr. Wegner stated that we have some brochures to encourage water conservation that we would like to send out early this year. Commissioner Yager stated that there was no mention in the Rules, Rates and Regulations in regards to water conservation and penalties associated with. It was discussed that we would prefer to educate on water conservation issues. Commissioner Froude stated that there is a need for consequences. She referred to U.S.A. rates being based upon usage. Ms. Froude stated that she felt the Board should discuss this issue. 8. Non Agenda Items No items were discussed. Chair Scheiderich stated that comments on the Rules, Rates and Regulations needed to be in by the March 22, 1995 meeting,. Mr. Scheiderich also stated that he would defer until the meeting on the 22nd to set the April meeting. 9. Adjournment Paul Hunt moved to adjourn which was seconded by Violet Yager. The meeting adjourned at 7:00 p.m. kathyliwbl3-8mtgAwb Intergovernmental Water Board, 3-8-95 Page 10 t: w InterOffice Memo To: Ed Wegner From: Michael Miller Date: March 8, 1995 Subject: Bids for Pulling Wells 2 and 3 I had Richard Sattler contact several different companies regarding the pulling and reinstallation of the well assemblies at well sites 2 and 3. He contacted a total of five different companies, but only three provided a bid. None of the bids included replacement parts for the wells. Lane Pump Company of Pasco, Washington, indicated that they were too busy to do a site inspection and submit a bid. However, they did provide a hourly estimate on the cost to pull and reinstall the wells. Their cost estimate was for $200 per hour, plus the cost to rent the crane or boom truck to pull and reinstall the wells. They would not provide a projection on the time requirements to complete the work. Lane Pump Company, unlike their well maintenance program in the mid-west, do not carry stock parts for our Peerless pumps, nor are they willing to stock these parts just for our agency. Ericksen Pump Company submitted a price quote of$6,500 to pull and reinstall the well assembly at well 2 and $8,000 to pull and reinstall the well assembly at well 3. This price includes the inspection of the well parts as the well is being pulled. As stated in the beginningof this memo, these quotes do not include refitting or replacement of parts. Mather and Sons Pump Incorporated, the same company that pulled well 1, submitted a quote of $2,500 per site to pull and reinstall the wells. This price quote included the pulling of the pump, inspection of the shaft and bearings, inspection of the bowl assembly, tear down for inspection and reinstallation of the pump assembly. Since none of the companies would submit a quote for replacement parts and labor, this is because they do not know exactly what will need to be replaced, we have estimated that the cost of the labor and replacement parts at $22.25 per foot of well shaft depth. This is based on the actual costs incurred during the retrofit of well 1 to current industry standards. For cost comparison purposes, I used the $22.25 per foot of well shaft depth estimate for all three vendors. Well 3 is also in need of chlorination equipment to chlorinate the water as it enters the distribution system, and other additional work to comply with current well head protection codes. The additional work at this site includes raising the well casing an additional T-0", pouring of a concrete slab and a wood frame structure to protect the well and chlorination equipment from the elements. Total cost for the chlorination equipment and well head protection is estimated at $6,200. In order to bring wells 1 and 2 into compliance with Oregon Health Division codes, regarding the mixing of chlorinated and non-chlorinated water supplies, chlorination Bids for Pulling Wells 2 and 3 03/08/95 Page 2 equipment was purchased and installed last year before they were operated. Therefore the purchase of chlorination equipment for well 2 is not necessary this year. Listed below are the quotes and cost estimates that we have received. Mather& Sons Ericksen Pump Lane Pump Well #2 Pull and reinstall $2,500 $6,500 $8,000 Repair/replace parts to bring well to $7,800 $7,800 $7,800 specification Total for Well #2 $10,300 $14,300 $15,800 Well #3 Pull and reinstall $2,500 $8,000 $8,000 Repair/replace parts to bring well to $10,000 $10,000 $10,000 specification Chlorination equipment $1,200 $1,200 $1,200 Improvements for well head $5,000, $5,000 $5,000 protection Total for Well #3 $18,700 $24,200 $24,200 Grand Total $29,000 $38,500 $40,000 It is my recommendation that we accept the bid from Mather and Sons Pumps Incorporated and begin the process for them to start pulling the wells as soon as possible, so that we can have the wells on line before summer. As we have discussed on other occasions, the usage of well water is an important part of our interium summer water supply plan. Although included in the overall cost, the chlorination equipment and most of the well head protection work would not be supplied by Mather and Sons Pumps Incorporated. However the estimates for the chlorination equipment and improvements for well head protection are accurate. CC: Randy Volk Murra};Smi r&ARciw,Inc. Enoeers/P niers 121 S.W.Salmon,Suite 1020 ■ Portland,Oregon 91204 PHONE 503-22x9010 ■ FAX 503.225-9022 94-0310.404 March 17, 1995 Mr. Mike Miller Operations Manager City of Tigard Water Department 13125 SW Hall Blvd. Tigard, OR 97223 Re: City of Tigard Interim Water Supply - Proposed Baylor Street Intertie Connection Dear Mike: In accordance with your request, we have prepared this letter that summarizes preliminary engineering efforts for a proposed intertie between the City of Tigard's and the Tualatin Valley Water District's (TVWD) water systems near Tigard's Baylor Street Reservoirs. Included are proposed piping and valving at the intertie, a construction cost estimate and scheduling considerations for the construction of the proposed intertie. Introduction The September 1994 Water Supply Plan Update completed by the City of Tigard presented recommendations for the development of a long term water supply to meet the City's water needs to the year 2020. Included were recommendations for providing interim water,supplies to the City as the long term water supply alternative is developed. Among the recommended interim supply alternatives to be considered were connections to the TVWD's water system. A preliminary review of potential intertie locations has been completed by the City and the District. This preliminary review found that a connection near the City's Baylor Street Reservoirs.provided favorable hydraulic conditions for a potential intertie. These favorable conditions include the close proximity of existing facilities and pressure conditions suitable for gravity flow from the District to the City. A hydraulic analysis of the proposed Baylor Street intertie and several other potential intertie connections under consideration by Tigard and the TVWD has been completed by the District. The analysis found that the flow rates available through the proposed Baylor Street connection vary greatly depending on local TVWD demands. The analysis determined that under estimated average day demand conditions approximately 0.7 million gallons per day (mgd) is available through the proposed connection. The District is presently performing fire hydrant flow tests in vicinity of the proposed connection to more accurately determine the actual hydraulic conditions near the 1 Mr. Mike Miller March 17, 1995 Page 2 proposed intertie. The District is also reviewing potential piping modifications that may increase flow rates available through the proposed connection. Hydraulic Review Tigard's two Baylor Street Reservoirs are located near the intersection of SW Baylor Street and SW 66th Avenue. The reservoirs each have a capacity of 1.0 million gallons, overflow elevations of approximately 416 feet and serve Tigard's 410-foot service level by gravity. The reservoirs were originally provided with separate inlet and outlet piping. The original inlet piping, presently not being used, was connected to an abandoned 12-inch diameter main belonging to the old Capital Highway Water District. This piping has since been connected to an existing TVWD 8-inch diameter distribution main which included a 6-inch diameter flow meter that was removed, rendering this connection inoperable. A 12-inch diameter transmission main, originally used as the reservoir outlet piping, now serves as both an inlet and outlet main to Tigard's 410-foot service level distribution grid. The reservoirs are located approximately a mile from the distribution grid. The water level in the reservoirs fluctuates only with change in the hydraulic grade of the distribution system. The reservoirs have had occasional water quality problems resulting from insufficient water circulation. A booster pump located on the 12-inch diameter transmission main between the reservoirs and the distribution system is available to pump water from the reservoirs into the distribution system and to provide for increased water circulation in the reservoirs. The TVWD presently provides water service to the area around the Baylor Reservoirs through 8-inch and 12-inch diameter piping within the District's 498-foot service level. The 498-foot service level is served from the District's SW Taylors Ferry Reservoirs located near the intersection of SW 65th Avenue and SW Taylors Ferry Road. These reservoirs receive supply by gravity through connections to the Washington County Supply Line. Proposed Intertie Connection The proposed Baylor Street intertie would connect a 12-inch diameter distribution main in TVWD's 498-foot service level to the original Baylor Reservoir inlet piping and to the 12-inch diameter transmission main serving Tigard's 410-foot service level from the reservoirs. Use of the original existing 8-inch diameter reservoir inlet connection was considered, however, to maximize flows through the proposed intertie, connection to TVWD's 12-inch diameter main in SW 68th Avenue was found preferable. The proposed connection configuration also allows the use of a single water meter for both connections to Tigard's piping. Mr. Mike Miller March 17, 1995 Page 3 This proposed connection configuration provides the opportunity for a direct water supply into Tigard's 410-foot service level or into the original reservoir inlet piping providing for improved water circulation in the Baylor Reservoirs. The existing facilities and the proposed intertie connection are illustrated in Figure 1. The proposed intertie connection includes piping, isolation valves, and a valve vault containing a hydraulically controlled pressure sustaining valve with flow control features and a flow meter. A schematic illustration of the proposed valve vault is also shown on Figure 1. Approximately 650 linear feet of proposed 12-inch diameter piping will connect the TVWD distribution system at the intersection of SW 68th Avenue and SW Baylor Street to the original inlet piping of the Baylor Reservoirs and to the 12-inch diameter transmission main serving Tigard's 410-foot service level. Three buried, manually operated isolation valves are included in the proposed piping configuration. These valves will be used to direct the flow from the intertie into the Baylor Reservoirs for eventual discharge into Tigard's 410-foot service level or to bypass the reservoirs and provide a direct supply into the 410-foot service level. The precast concrete valve vault is proposed downstream of the connection to TVWD's system. The vault will contain an 8-inch diameter flow meter and an 8-inch diameter hydraulic control valve. The flow meter will serve as a meter for flow measurement and will include provisions to electronically transmit flow rate information to the valve so that the flow limitations of the intertie are not exceeded. The hydraulic control valve will be a pressure sustaining type valve with settings and adjustments to allow flow through the intertie without excessive pressure reductions to TVWD's distribution system in area of the intertie. The valve will also include settings to limit the flow through the valve to the predetermined amount. ,The flow meter will require electrical power for electronic flow signal generation. As part of this project Tigard should also examine the existing valving of the original inlet piping at the Baylor Street Reservoirs to confirm that these valves and their controls are in proper working order. TVWD System Improvement An additional system improvement will be required as part of this proposed intertie to improve supply to the TVWD's Taylors Ferry Reservoirs. An existing 10-inch diameter flow meter, referred to as the Florence Lane Meter, on the transmission main connecting the reservoirs to the Washington County Supply Line will require replacement with a new 16-inch diameter flow meter. Through discussions between Mr. Mike Miller March 17, 1995 Page 4 the City and District, Tigard has agreed to share up to $15,000 in the cost of this meter replacement. Construction Cost Estimate The total estimated construction cost for completion of the proposed intertie and Tigard's share of the Florence Lane Meter replacement is approximately $91,000. This construction cost estimate for the intertie assumes construction by a private contractor. Included in the construction cost estimate for the proposed 12-inch diameter water main are connections, isolation valves, fittings, trench excavation, backfill and surface restoration. Included in the valve vault estimated costs are the pressure sustaining hydraulic control valve, flow meter and vault electrical supply. Not included in the estimate are costs associated with improvements to Tigard's existing telemetering system related to the intertie. An itemized breakdown of the estimate is provided in Table 1. Table 1 Construction Cost Estimate Summary Item Estimated Cost Water Main - 650 If of 12-inch diameter main $ 44,000 Valve Vault (Exclusive of telemetry improvements) 22.000 Subtotal $ 66,000 15% Contingency 9.900 Total Estimated Construction Cost $ 75,900 (Say $ 76,000) Florence Lane Meter Replacement (Tigard's Share) $ 15,000 Project Schedule Tigard and the TVWD are presently developing an intergovernmental agreement for water service that provides the legal and institutional framework for the supply of water from TVWD to Tigard. With the substantial development of the intergovernmental agreement, further engineering efforts should be completed for the proposed Baylor Street intertie. These include a design survey of the project site and L v Mr. Mike Miller March 17, 1995 Page 5 the development of design drawings and contract documents for the construction of the proposed intertie. Tigard may also consider purchasing the flow meter and the pressure sustaining flow control valve in advance of project construction to minimize acquisition lead times on these items. Conclusion The proposed Baylor Street intertie is one of several potential interim water supply connections between the TVWD and the City of Tigard. The proposed intertie provides for a gravity supply of water from TVWD's 498-foot service level into Tigard's 410-foot service level. The estimated construction cost of the intertie and related system improvements is approximately $76,000 plus an additional $15,000 for Tigard's share of the Florence Lane Meter replacement. We appreciate this opportunity to provide our services to the City of Tigard.

At our meeting on February 8, 1995,with yourself and Bill Monalanh we haon deswide- ranging discussion as to the- desired location of a water right appy Willamette River. A key topic of discussion was whether to locate the point of diversion in the application above or below Willamette Falls at Oregon Citi'. As a result of these discussions,the decision was made to proceed with the application at the WiWonville location. The following is a summary of the discussions items that led to that decision: o The Wilsonville site is the location of one of the regional sources being considered in the rcgomil water supply planning studies presently ongping_ Substantial water supply studies of this location have boon conducted. A site on the Willamette River below Willamette Fails is not presently being considered Zor such a regional source. 0 While Tigard could proceed on its own vvith a water supply system if it were to obtain water rights at any location, the Wilsonville site presents the best opportunity to develop a joint crater supply system with other participants to achieve the,greatest economics of scale for such a system. The G�ty Of Wilsonville and the Tualatin valley Water District bath hold substantial water rights at the Wilsonville location. The City's application would be for a point of diversion at the same location. The potential to develop a joint supply below Willamette Falls with others such as the City of lake Oswego is far less cert0in. A supply system at this location would be far less likely to be developed with others and would therefore likely not present opportunities for economies of scale.

FAX NO. 503 225 9022 P. 03 Mr. Ed Wegner Page 2 Mauch 21, 1995 t o The siting of an intake and treatment facility below Willamette Falls would present significantly greater physical c omstruction obstacles than would the Wilsonville site. The west bank of the Willamette River in the West Linn and Lake Oswego area is now substantially developed. SWffiicant siting difficulties for a large intake and treatment works would be anticipated at such a site. o The pre-1909 claims at Willamette Falls by Portland General Electric Co.for hydroelectric power generation present an obstacle to he considered at the Wilsonville site. These claims are senior to most other upstream rights on the entire Willamette River system including those of others at the WIL-A nviRe site. It was determined that this obstacle, while potentially serious,could eventually be.favorably resolved such that a water supply system at WflsonvilLe could be developed with confidence that a firm raw water supply is available. P.a--&A upon the present understanding of the water rights and other related issues concerning development of a water supply for the City, it was determined that application for a right on the Willamette River at Wilsonville offers the City the best opportunity to develop a new water supply.

We have completed this work in accordance with your direction at our meeting on February 9, 1995. The application includes several items which we would like to bring to your attention: 1. The point of diversion on the Willamette River will be at Wilsonville west of 1-5 on the north bank of the river. We have described the diversion point at the same point as that described in the existing rights of the Tualatin Valley Water District. 2. Land use information forms will need to be submitted to the following: Washington and Clackamas Counties, Cities of Wilsonville, Tualatin, Tigard, Durham and King City. We will obtain a receipt for the information form from each of these entities after approval of the application by the Council. The receipts will be then be forwarded with the application to OWRD. Each entity has 30 days within which to respond and forward the land use information form to the OWRD. 3. We have developed the estimated ultimate water demands based upon the ultimate service area (9,732 acres) shown on the enclosed service area map, the assumption of 6.5 persons per acre ultimate population density, and the assumption of 400 gallons per capita per day maximum daily demand for that population. These assumptions thereby result in an ultimate maximum daily water demand of 40 cubic feet per second or 25.9 million gallons per day. This methodology to develop ultimate maximum daily demands was used because ultimate demands have not been identified in the City's current water system master plan update which developed year 2020 demands or the Phase 2 regional study which is developing year 2050 demands. Mr. Ed Wegner February 22, 1995 Page 2 Please review this information at your earliest convenience and if you have any questions or desire any changes to the application or supporting documents, please call. Upon Council approval, please have the application signed by the appropriate City official and return the original documents to us. We will then obtain the land use form receipts and file the application with the State on your behalf. At the time of filing, a $200.00 check payable to the Oregon Water Resources Department will be required. We appreciate the opportunity to assist you with this work and please call if you have any questions. Sincerely, MURRAY, SMITH & ASSOCIATES, INC. P p H. Smith, P.E.
