Resolution to approve minutes of last meeting,. 2. Visitors. a. Dr. R. A. Bissett intends to appear before the Board regarding the district's alleged responsibility to level the fill dirt on his property which was hauled by the contractor from the new Hi Tor reservoir. (See letter attached). When it became known to the public, about 1- - years ago, that excess fill dirt would be available upon excavating for the new Hi Tor reservoir there were at least 8 property owners who expressed a desire for the dirt. In addition, other property owners were willing to pay the contractor for each load hauled to their premises. John Miller was advised by Dr. Martin Johnson that Dr. Bissett wanted some fill dirt. Since Dr. Bissett's residence was closest to the reservoir site (and thus the cheapest disposal site) John called upon Dr. Bissett. Evidently, there was a misunderstanding about leveling the dirt after dumping. John states that he does not recall telling Dr. Bissett that either the contractor or TWD would grade the fill dirt. The district does not possess equipment to accomplish the job and such work must be performed by private contractor. Estimated cost: $300. b. Mr. Jim Harris of Harris & McMonagle (Engineers) intends to appear before the Board and request permission to perform the engi- neering work on water main installations for specific sub-divisions. You have indicated in the past that you desired the Administrator to perform this function. Most engineers when designing a sub-division prefer to plan all utilities, including streets, sidewalks, sewers, storm drains, water, etc. -1- ADMINISTRATOR'S REPORT (Continued) Aside from the income gained from the 8$ of construction costs there are distinct advantages in retaining this function within the district. We are familiar with the master plan, existing pressures, sizing of mains, number of dwellings which can be served, fire pro- tection requirements, etc. Other engineers often do not supervise the installation adequately, resulting in shoddy workmanship. Also, by utilizing outside engineering firms you have lost control of the system. I have managed to keep up with the workload and believe that only one engineer should do the design work. If it is not correct, you have a recourse. 3. Resolution to pay vouchers. SOW 4. Resolution to approve lowest acceptable bid to raise elevation of reservoir #3 by 12 feet. At 1:30 p.m., September 12th, (date of the meeting) the Washington County Planning Commission will consider the district's application for "conditional use" to raise the elevation of reservoir #3 by 12 feet. The Planning Commission is now the final authority on these matters; thus the request will not be referred to the County Commissioners. Also, on September 12th, Elden Carter will have bids from competent contractors to perform the work. It should be noted that the consulting engineers arrived at the same solution in design as suggested by some of the commissioners at the last meeting. The existing concrete top will be sawed off around the outside rim and the walls extended on top of the existing walls. Most of the present top will remain in tact inside the new tank. This goes to prove that the commissioners are good engineers too. 5. Resolution to approve solicitation of bids for $480.000 of bonds and approve the notice of the bond sale. Ken Baines has prepared the resolution in detail which will be available at the meeting. -2- 006. ADMINISTRATOR'S REPORT (Continued) 6. Resolution to approve revised rules, rates, and regulations. One more time. 7. Resolution to approve contract with City of Lake Oswego to purchase surplus water. Mr. Deane Seeger, City Manager of Lake Oswego, has prepared a contract for your review and consideration. (See attached). In general, the contract appears acceptable. Ken Baines and I have a few suggestions which will be discussed at the meeting. Lake Oswego is particularly interested in serving the district on a daily basis. CH2M estimates that by committing Lake Oswego to providing water for Tigard would mean increasing the capacity of the __ treatment plant 6 years earlier than originally planned. Lake Oswego would use the revenue from Tigard to improve their capability to pro- duce more water. It was suggested that Tigard buy a minimum of $70,000 annually at 14¢/100 cubic feet. I informed them that the Board desired to continue pumping from the wells, and as the wells depleted, more and more water would be purchased. A compromise minimum figure of $24,000 was offered and written into the proposed agreement. The initial length of the contract would be 4 years with options to renew the contract each 4 years thereafter. To obtain a better understanding of this minimum figure, the following data reflects the charges by Capitol Highway Water District for 1972; Month and Year Cubic Feet Cost May 1972 158,900 $ 604 June 1972 1,978,700 7,519 July 1972 4,169,200 15,843 Aug 1972 4,909,000 18,654 AORK Sep 1972 (est.) 1,942,000 7,380 13.157.800 $50.000 or 98.684.000 gallons -3- ADMINISTRATOR'S REPORT (Continued) One can estimate that there will be at least a 10,$ increase annually in water consumption by the TWD. Thus, savings would accrue as follows: (It should be noted that $24,000 worth of 14¢ water would cost $65,000 at 38¢). Year Cost CHWD Cost L.O. Savings 1973 $ 55,000 $ 24,000 (min) $ 31,000 1974 60,500 24,000 (min) 36,500 1975 66,500 24,500 42,000 1976 73,200 27,000 46,200 1st 4 years: $155,700 1977 80,500 29,700 50,800 1978 88,500 32,700 55,800 1979 97,400 36,000 61,400 1980 107,100 39,600 67,500 2nd 4 years: $235,500 Total for 8 years: $391.200 It would appear that after 5 years the district's capital investment would equalize the savings accrued by purchasing from Lake Oswego versus Capitol Highway Water District. Ownership of the main from I-5 to Waluga Reservoir was discussed. It is mandatory that the master meter be set near the reservoir or if the meter is installed near 1-5 that the district be rebated for any subsequent connections between I-5 and the reservoir. If the latter is the case, it should be included in the agreement contract. -4- Amir ADMINISTRATOR'S REPORT (Continued) 8. Resolution to approve lowest acceptable bid to install 4,000 feet of 16-inch ductile iron pipe along S. W. Hall Boulevard, from Mac- Donald to Bonita, and along Bonita, from Hall to Fanno Creek (75th). At present, district personnel are involved with several main installations of 6", 8", and 12" caliber. It is very important that these mains be installed along with the 16" transmission main during the good weather. Bids have been received from two contractors (for labor only) to install the main from Hall Boulevard and MacDonald to Fanno Creek on Bonita Road. (4,000 feet). This is a very difficult section to install and some special equipment will be required. Bids were as follows: Cornell Construction Co. (Forest Grove): $3.50/ft Arndt-Colt Construction Co. (Portland): $4.37/ft Bunyard and Pettitt (Portland): No Bid It is estimated that $4,000 could be save in labor costs by employing district personnel on this transmission line. However, our personnel cannot perform all of the tasks that are pending. It is estimated that an equivalent amount can be earned by district personnel during the same period of time by installing smaller-sized mains for developers; namely: School District 23J: 900' of 6" behind THS Burnham Park development: 1000' of 6" Pathfinder development on Fonner:1200' of 6" Apt. unit on 76th and Bonita: 400' of 8" This does not mean that all 16" transmission mains should or will be installed by private contractors. At this particular time there are several other jobs to complete in addition to the concern to "beat the bad weather". Our goal is to have an alternate source of water by May 1st , 1973. Help in the workload at this time would relieve the pressure. 9. Other business. -5- w ADMINISTRATOR'S REPORT (Continued) 10. Purchase of 16" D.I. pipe (Class II) Quotations were requested from the two pipe manufacturers for 20,000 lineal feet of 16" transmission main which is enough pipe to connect to both Lake Oswego and Portland. These bids are valid for a 2-year period. Bids were as follows: U. S. Pipe: $8.32/ft Pacific States: $8.462/ft 11. Purchase of Bull Run water at Bradley Corners. Elden Carter reported that Portland Bureau of Water Works has agreed to a rebate agreement to the three water districts involved for the 24" main to Bradley Corners. This was the main obstacle in '400, the contract agreement. It will be difficult to enforce the requirement that the TWD be guaranteed 1/3 of the water in the line. The concept employed by both Portland and Lake Oswego is that everyone is treated the same with no priorities, except their own citizens. In other words, everyone has an unlimited supply or everyone is restricted on water usage. They believe it would be unfair, for example, to "cut-off" one district entirely, but allow, at the same time, another district unlimited water consumption. The present status of the Portland agreement is as follows: Mr. Birnie, attorney for both Metzger and Progress Water Districts, is to meet with Ken Baines and prepare a legal contract for presentation to the parties involved. It will be an inter-governmental type of agreement. How long it will take Birnie to accomplish this is anybody's guess. 12. Water from Scoggins Dam. The City of Hillsboro is sponsoring a program to solicit assistance from other cities and water districts on construction of mains and a No., reservoir from the new Scoggins Dam which will be completed in about 4 years. The attached newspaper article describes the proposal. Total cost of the project is $9.9 million, but will get a 45" transmission main to the east side of Hillsboro only. Tigard is a long way from that point. They have asked for a commitment by September 21st so that engineers can proceed with the project. -6- ■ ,* z V;-PA �� a- ;44', =`d.3i Cooperative prfc• f st r rd r By JAMES MAGMER, water we receive from.other loo 7h.Oneonta stiff cities," city manager Eldon wirisB9Ro--A coopera- Mills said. tive system to supply 36 mil- The cost of increasing the lion gallons more water dal- size of the pipe.will be the• lY was--proposed to the cities cost charged other cities for and water districts of Wash- their share in the project, • ington County by the City of Mills said.

New well. A letter was written to Mr. Wm. S. Bartholomew, Oregon State Geologist, requesting information whether the State Engineer would accept our application to drill another well at the location recommended by Mr. Newcomb. No response has been received. The Oregon Board of Health also has restrictions on well sites, some of which are noted below: a. A map showing the source of supply, the proposed location of the well, spring or diversion, drainage area involved, known sources of ground water, general topography, the locations of septic tanks and seepage pits, industrial waste, petrochemical storage and any potential sources of chemical, physical or biological contamination. b. Laboratory data from a commercial laboratory, certified by qualified personnel, attesting to the biological, chemical, radio- logical and physical quality of the water as established by the O.S.B.H. Bacteriological samples shall be submitted to the State Hygenic Labora- tory for examination or to a laboratory approved by the State Hygenic Laboratory. c. Field data certified by qualified personnel attesting to physical conditions such as well log, pump test, stream flow measurements, flood levels and other data concerning the quantity of water as necessary to determine the adequacy of the supply. d. Documentation of legal requirements such as property ownership, property easements, water rights or other state and local law or regulations. e. The transmission and distribution systems, with further information as to the design flows, velocities and expected system pres- sures. f. The kind and character of the works for gathering, treating and storing the water complete with engineering design data showing the adequacy of the proposed works. g. The services to be supplied, the expected water uses, average and maximum demand flows and the reserve capacity provided for future growth. -8- le.. ADMINISTRATOR'S REPORT (Continued) h. When a well is to be provided for supplying either a new or existing system, specifications for construction shall be submitted to the division for review and approve' and shall be approved before the well is drilled. As soon as available, a well log, an analyses of the water as set forth above, a record of test pumping with a pump rate versus drawdown curve and bacteriological test results shall be submitted to the division. The project shall be approved before the well is connected to the water system. 14. Inspection by Oregon State Board of Health. It becomes more obvious every day that the O.S.B.H. will take a more active role in carrying out its responsibilities to ensure adequate, safe water for the citizens of Oregon. They recently placed a ban on all new construction in the Aloha-Huber Water Dis- trict because of an inadequate water supply. At the instigation of a group of "Little Bull Mountain" residents who object to the proposed Summerfield (King City II) project, the O.S.B.H. made a complete inspection of the Tigard Water District. A copy of the comments of the engineer is enclosed. The corrections needed at the well sites will require lifting the pumps with casings which involves contracting for a crane. The correc- tions are not of an urgent nature, but should be accomplished as time permits. 15. Purchase of terminal reservoir site. Mr. and Mrs. Ben Larson accepted the district's offer of $18,000 for 3.1 acres of land for a terminal reservoir site on S. W. 125th, north of Bull Mountain Road. An earnest money agreement of $10 was completed. The purchase is contingent upon obtaining a "conditional use" permit to construct the reservoirs. Such application has been submitted to Washington County. This purchase will complete the district's reservoir site needs for many years. With the 7 million gallons of storage now on hand, reservoirs can also be constructed at the following locations: -9- ADMINISTRATOR'S REPORT (Continued) 125th and Gaarde (Larson) 10 million Hi Tor (2nd tank) 1 million #3 Site (2nd tank) 1 million 12 million The ST&R Study indicates that 23 million gallons of storage will be needed by year 2000 of which 19 million can be accounted for. It should be noted that the district owns about 4- acre of land west of reservoir #2. Unfortunately, the property is too low, at present, for a reservoir site. Perhaps the land can be filled at some future date. 16. Fanno Creek crossing on Bonita Road. In view of the Board's interest at the last meeting of making a connection with Lake Oswego prior to Portland I re-examined the con- struction plans to Lake Oswego. A crossing at Fanno Creek on Bonita Road had to be accomplished prior to the rainy season. Accordingly, after consultation with several members of the Board it was decided to make this crossing now. To eliminate a future need for a crossing at this location, a 24" D.I. (high pressure) transmission main was installed with a parallel 12" D.I. main next to it for domestic services. Installation costs were estimated at $4,000. Cornell Construction Company bid $3500 to install a 16" and a 12" main, and $3800 to install a 24" and a 12" main. They were awarded the contract for $3800. The completion of this crossing provides the Board with the option of making a connection at either Lake Oswego or Bradley Corners by next summer. 17.

I have asked for an appointment on your agenda at the September 12th board meeting. The reason for this visit is as follows: Approximately two years ago, I was approached by Dr. Martin Johnson (a board member) about the possibility of dumping earth from the proposed reservoir on my pasture land since it was the closest available site. I agreed that this was possible and asked to have someone from the district contact me. John Miller later stopped to see me and said that my site was desirable. I then asked John about the leveling of the of the dirt Now piles and he definately said that this was no problem because this is what the contractor commonly did in such situations. The dumping of dirt was accomplished approximately one year ago and since that time I have talked to John and Mr. Wiggins on numerous occasions about when the leveling would be done. The replies have been varied but that this would be done as soon as possible. About two weeks ago I noticed that the equipment was being removed from the reservoir site and so I once again asked about the leveling and was informed for the first time that I would have to pay for this service. I asked John about this and he expressed surprise, but then told me that this was between me and hr. Wiggins. My position is that I had a firm understanding with John, and that At was his responsibility to complete the job committed to by him. I am not asking the district to bear the burden of this cost, but to implement the completion of this commitment by whatever means available to them. Sincerely, Bob Bissett ter.► RAB/rp City of Lake Oswego September 1, 1972 Mr. Robert Santee, Manager Tigard Water District 8841 S. W. Commercial Tigard, Oregon Dear Bob: I am enclosing, without any pride of authorship, a proposed draft of agreement for consideration by your Board. While the overall format conforms substantially to the Agreement now in force with the City of Tualatin, I have ter• tried to include language that reflects general "good faith under- standings" tentatively reached in the course of our discussions during the past few months. After a series of false starts, I finally concluded that this might be best accomplished in a "statement of purposes" (page 1, pgh. 4) . If, after review by yourself and attorney, you wish to present this draft to your Board, I am prepared to attend your meeting. In the meantime, please feel free to present any objections, comments or suggestions. Sincerely, Deane Seeger City Manager DS:hb cc: M. De Haas, Public Works J. A. Cox, City Attorney Now City Hall • 348 N. State Street • Lake Oswego, Oregon 97034 • Telephone — 636-3601 %rrs AGREEMENT FOR WATER SERVICES THIS AGREEMENT, made and entered into this day of 1972, by and between the CITY OF LAKE OSWEGO, a municipal corporation of the State of Oregon, hereinafter called City, and the TIGARD WATER DISTRICT, also a municipal corporation, hereinafter called District. Witnesseth: WHEREAS, District desires to obtain water from City and City is will- ing to furnish such water upon the terms and conditions hereinafter set forth, Now, Therefore, the parties hereto hereby agree to and with each other as follows: The services and commodity provided by City under the terms and pro- visions of this Agreement are a special contract service and not provided by City as a common utility service. It is hereby declared to be the purpose of this Agreement to: Nor 1. Make available to District surplus water supply from City to reasonably meet District's normal daily requirements. 2. Guarantee to City an annual income of not less than $24,000 from sale of surplus water to District. 3. Establish a balanced schedule of purchase and delivery of such water that will best serve the needs and requirements of both City and District. District recognizes and agrees that City will furnish and sell water under the terms and provisions of this Agreement, and it is the duty of City to furnish water at normal volume and pressure to the City and its inhabi- tants before selling or furnishing any water to District; however subject to the above mentioned exceptions and those hereinafter set forth, City will endeavor to maintain on its distribution system at the point of the District's connection a normal volume and pressure flow. District shall construct, at its own expense, all water system im- provements necessary to connect the District system to the City system, in- cluding a master meter, valves, controls and appurtenances, as approved by City and as shown in Exhibit A attached hereto and made a part of this Agreement. "' .' District agrees to pay monthly to City, on or before the 21st day of each month, for all water delivered to District during the immediately preceding calendar month at the rate of fourteen cents (140) per 100 cubic feet as measured by the master meter at point of connection. It is further understood and agreed that the aggregate of such monthly payments for each 12-month period, beginning with the effective date of this Agreement, shall total not less than Twenty-four Thousand Dollars ($24,000.00) , for which District will be entitled to receive up to 128,640,000 gallons of water for said 12-month period. Should the meter at any time fail to measure accurately the surplus water passing through said meter, the charge for such water delivered during the time the meter is out of order shall be based on the estimated volume of water supplied as City and District may determine by using averages and statistics for prior periods. iwww City reserves the right at any time to review the rate and schedule of charges for surplus water heretofore made a part of this Agreement, and to make such adjustment in the rates as may be found necessary in the sole discretion of City, to reflect increased costs for the production and dis- tribution of surplus water under this Agreement. In the event that Lake Oswego adjusts and/or increases said rates, any increase shall not become effective until not less than 60 days written notice of such rate change is given to District. This Agreement shall be effective, except as hereinafter provided, for an initial period of four years from date of execution, and shall auto- matically be renewed for subsequent four-year periods, subject to the pro- visions hereinafter set forth. This Agreement may be terminated by City at the end of the initial four-year period, or the end of any subsequent four-year period, by giving at least one year's written notice of its intention to do so upon City's good faith determination that insufficient water is available to meet Dis- trict's requirements and the requirements of City's own system. Termina- tion may be effected by District upon the giving of not less than 60 days' written notice to City for such reasons as District, in its sole discretion, might determine. City reserves the right to interrupt or curtail deliveries of surplus wr, water to District, but in such event will make every reasonable effort to give advance notice of service curtailment to District. District, in turn, agrees to fully utilize other available supply sources during concurrent periods of high demand upon District's and City's systems. City shall own, operate, maintain, repair or replace all water system facilities necessary to furnish water to the outlet side of the master water meter used for measuring the quantity of water delivered to District, but City shall make no separate charges to District for such maintenance, re- pair or replacements. Termination of this Agreement by either party for any lawful reason, or non-delivery of water by City by reason of unavailability of surplus water, shall not relieve District of any obligation for payments thereto- fore accrued under this Agreement This Agreement shall become effective upon execution by City and District, and the obligations of both parties hereunder shall commence the day and month water is first delivered by City to District. In Witness Whereof, the parties hereto have executed this Agreement the day and year first above written.

DIVISIONS Health A review of your records of water storage in your reservoirs this Children's Services Corrections summer indicate that there has been a significant improvement in Employment transmitting water from the Baylor reservoirs to the west end of wr Mental Health Special Programs your system to meet the peak demand conditions. This is accomplished Vocational Rehabilitation in part by the installation of the Hunziker Road pumping station, Welfare the surplus supply from the Capitol Highway Water District, and the improvements of the distribution system in recent years. During our survey we noted some changes needed at your existing wells. The well casings do not extend above the concrete slab of the pump house. These casings must be raised at least 18 inches above the slab and be fitted with a sanitary well seal to prevent contamination en- tering the top of the wells. In addition, the casing must have a vent. This vent will allow free flow of air to prevent a vacuum in the casing. The vent should be fitted with an elbow turned downward with a screen to prevent contamination from being drawn into the well. Reportedly, the oil lubricated pump for well #4 has developed leaks causing a gradual accumulation of oil scum in the reservoir. This well has a comparatively high operating cost because of its great depth. The district should consider replacing this pump with a water lubricated pump or use this well only as an emergency supply. There is no auxiliary power provided for the booster pump stations. Incase of electrical failure, the areas pressurized by the booster stations will be out of water until the electricity is restored. In order to increase the reliability of your system, the provision of standby power should be included in the future planning of your system grow improvement.
