The new backhoe will not be purchased until after the 1st of July when the new fiscal year be- gins. 6. Resolution to drill a new well at Baylor reservoir site. A search was conducted for potential deep well sites as recom- mended by Mr. R. C. Newcomb, Consulting Geologist, in his study of June 29, 1972. He suggested three possible sites which have poten- tial and which are out of the critical ground water area. These three sites are located as noted below: -1- ADMINISTRATOR'S REPORT (Continued) #1: S. W. Greenburg Road and Highway #217. #2: S. W. 72nd and Pacific Highway, near Fred Meyer. #3: S. W. 72nd Avenue and Highway #217, near Phil Lewis School. Site #1 is located in an area zoned for industrial use. Cost of land in this area averages $40,000 per acre. In view of this, serious consideration was given to sites #2 and #3. After weighing all factors, including the proximity of sites #2 and #3 to existing mains, it was deemed appropriate to consider drilling a well at the Baylor reservoir site where the district already owns the land. A letter was sent to Leo Farr, Director, Public Health Engineering, requesting a waiver of land ownership 100 feet in all directions of the well. He has tentatively approved the waiver (by telephone) and will w.., support the concept by letter. The economic advantage of well water versus imported surface water cannot be overemphasized nor disputed. Cost to amortize the initial investment plus maintenance expenses for well water is, at most, 5c per 100 cubic feet. A chart of well capacity versus savings from imported surface water is shown below: Savings Lake Oswego(25c) Portland(310) Well Capacity Well Capacity Cu.

The gamble is worth the results. $27,000 has been budgeted from the General Fund for this project during the next fiscal year. Your permission is requested to obtain the necessary permits and commence receiving bids for a well to be drilled at the Baylor reservoir site. -2- ADMINISTRATOR'S REPORT (Continued) 7. Other business. 8. General Obligation Bond Issue. On May 25th, at the primary election, the patrons of the water district approved a G. 0. Bond Issue of $1.9 million to construct a reservoir, transmission mains, purchase future reservoir sites, and replace old water lines. The count was as follows: Yes: 3,371 = 61.5% No: 2,111 = 38.5% 5,482 100.0% As a comparison, at a special election in August 1971, a $980,000 G. 0. Bond Issue resulted in a count as follows: Yes: 312 74.3% No: 108 = 25.7% 420 100.0% Obviously, this past election was more representative of the true feelings of the electorate. Our message must have been received, and a majority approved of the concept presented for capital improvements. 9. Capital Improvements Time Schedule. The burden is upon us to accomplish the major capital improvements in an expeditious manner. Of course, the largest part of the bond issue will be spent on the 10 MG reservoir. The preliminary plans and specifi- ,w„ cations will be received this week. -3- ADMINISTRATOR'S REPORT (Continued) It has been recommended that there be two contracts; one for the excavation and one for construction of the reservoir. There will really be three contracts because a private contractor will have to build the vault with valves, etc., and the 36-inch main from the reservoir site to 121st and Gaarde Street. I am hopeful that the excavation contract can be awarded on July 13th, at the regular meeting. However, work cannot commence until after approval for "conditional use" by Washington County Planning Commission. A public hearing has been established for July 27th. It is planned that the contract to construct the reservoir can be awarded on August 10th, at the regular meeting. Much of the con- struction, particularly the concrete floor, can be poured prior to the rainy season in November. Throughout the Winter and Spring 1977 the contractor can select the better days to perform the actual work. Ato.' Next summer the pre-stressing can be accomplished. The tank should be finished by late 1977 and ready for use in the Spring 1978. 10. Bond Issue Time Schedule. A tentative date of November 9th, a regular meeting date, has been established to sell the bonds. This may appear to be a long way off, but much needs to be done prior to selling the bonds, and most of the funds cannot be used before that time. Funds required prior to that date can be borrowed at the local banks on a short-term basis, if necessary. The first requirement in selling the bonds is to prepare a prospectus in compliance with Oregon Revised Statutes for bond issues in excess of $1 million. In this regard, it is recommended that the entire issue be sold at one time and not in increments. I will be working closely with Ken Baines in the preparation of the prospectus. It is important that these bonds be rated by Moody's Investors Service, Inc. The prospectus will contain most of the information required by Moody. The latest financial data available should improve *ay -4- L.. ADMINISTRATOR'S REPORT (Continued) the district's chances of obtaining a AAA bond rating. Therefore, data as of June 30, 1976 should be used. The latest audit report as of June 30th will be completed about mid-August. By September 1st Washington County will have information on assessed valuations, largest taxpayers, etc. Data on over-lapping bonded indebtedness of other tax-levying bodies, as of June 30, 1976, are being solicited now. Moody's should complete their rating report by October 1st. Thereafter, selling of the bonds can be published to prospective bidders. There are some other reasons for recommending a November date for selling the bonds. Even though the bonds are sold during Novem- ber, maturity dates of January 1 and July 1 can be established for the semi-annual payments. This is important in later years because tax funds are not actually received until December of each year. Therefore, with a January 1 due date, funds do not have to be bor- rowed, on a short-term basis, to pay for bonds becoming due. It is my understanding that funds derived from G. O. bonds must be expended within a two year period or the district could lose its tax-exempt status. Selling the bonds at a later time lengthens the terminal date to December 31, 1978, at which time, I am confident, all proposed capital improvements from the bond issue can be completed. -5- ADMINISTRATOR'S REPORT (Continued) 11. Water source for the long-range time period. With the bond issue approved, funds will be available to solve all of the distribution and storage needs of the district until about 1990. However, the independent source problem is still with us. There is no crisis situation in this area, and as long as we are willing to pay the price for imported surface water, the district should survive several more summers without a significant water , shortage. Concurrently, with our other plans, we must continue to explore all potential sources of water. For several years, it was believed that the district had two realistic potential surface sources of water; namely: (1) runoff from the coast range, and (2) the Willamette River. After more study and advice I believe this option can be re- duced to only ones -- the Willamette River at Wilsonville. Coast Range. The City of Beaverton has been advised that unless they sign the 10-year contract with the City of Portland by July 1st, they will re- ceive no more Bull Run water. Whether this actually happens remains to be seen. Beaverton is considering a plan to construct a 12-mile pipe line to Hillsboro and utilize Scoggin Dam water as their primary source. This appears to be a logical source of water for both Beaverton and Wolf Creek Highway Water District. Unfortunately, the supply is lim- ited. There is only 12 MGD at Scoggin Dam and 3 MGD at the Trask Dam. Both Hillsboro and Forest Grove utilize, or will soon utilize, water from these sources. Wolf Creek Highway Water District has used as high as 18 MGD during peak demand periods. Recently, it was announced by Representative AuCoin that Congress would hold a hearing on Tualatin, Phase 2, for another dam at Mt. Richland, near Gaston, which would produce 18 MGD of municipal and industrial water. If approved by Congress, the dam would become a reality in 10 to 15 years. Now -6- sow ADMINISTRATOR'S REPORT (Continued) In view of the limited amount of water in the coast range, and the extensive needs of intervening water purveyors, it is believed that Tigard Water District should abandon any plans to develop water sources in the coast range. Recommendation 1: That TWD withdraw from any thoughts about partici- pating with Wolf Creek Highway Water District in a water source study. Recommendation 2: That TWD donate its water rights at Scoggin Dam (2500 acre-feet or 2.2 MGD) to anyone who may care to use it. Willamette River. All roads seem to lead, in the end, to the Willamette River as olow the future source of water for the Tigard Water District. I had an interesting conversation recently with Leo Farr, Director, Public Health Engineering, regarding the Willamette River as a source of water. He agrees that potential sources of water are limited and that perhaps the Willamette River would be the best source of water for Tigard Water District. He thought that the Health Division would look more favorably upon tapping the river at Newberg versus Wilson- ville. This upstream location can be considered, and is a possibility, but the cost would be slightly higher because of the longer pipe line along Pacific Highway (99W). A treatment plant at Newberg would not solve the water source problems for either Tualatin or Wilsonville, where the future needs will be great. The high growth area will probably occur along the 1-5 corridor between Tigard and Woodburn. It is inevitable that a water main, at some time, will have to be constructed between Tualatin and Wilsonville if growth is to be sustained. Both Newberg and Sherwood are content with their deep well supply of water so there is no hope of assistance from those two entities. The 6-month test results of the chemical analysis of Willamette River water at Wilsonville are encouraging. SUR report no adverse elements or pesticides present which could not be treated satisfactorily. -7- ADMINISTRATOR'S REPORT (Continued) The psychological problem of consuming treated Willamette River water by the patrons still persists, and probably will not go away until there is a water crisis of major proportions. This may not occur until 10 or 15 years from now and perhaps not during our life- time, at least not mine. However, the responsibility is upon our shoulders to find a solution before a major crisis develops. I suggest an interim solution such as described below. A statement Hugh Brown made some years ago continues to haunt me. He stated, "well water is abundant further south in the Willamette Valley". If this is true, why not take advantage of this fact? The following paragraph is quoted from a Ground Water Newsletter dated August 1972: 4100., "For thousands of years ground water has played the waiting game. Virtually disregarded in spite of the fact that it accounts for 95% of the earth's po- tential fresh water supply. Now....as pollution of surface water increases...Now....as there seems to be no easy solution to the problem....Now....ground water is finally achieving the status it has so long deserved. Right now.... 20% of the fresh water used in the U. S. is ground water.... 957. of the rural population is entirely dependent upon ground water.... 20 of the 100 largest cities in the country are entirely dependent upon ground water. And this is just the beginning!" If these statements are true we would be remiss in not exploring deep wells in the vicinity of Wilsonville, north of the Willamette River. The City of Wilsonville has one well which produces 0.7 MGD 44110., versus the 4 deep wells of TWD where total production has diminished to 0.8 MGD. Well water could be pumped to the proposed 10 MG terminal reservoir on Bull Mountain. -8- Now ADMINISTRATOR'S REPORT (Continued) At some future date a treatment plant could be built to filter and soften the well water just as Parkrose Water District does now. In the years ahead, when and if the ecologists finally achieve their goal of 100% clean rivers, the Willamette River may be acceptable to the public and could be tapped, using the same treatment plant. This, in effect, with a slight variation, was the course of action taken by the City of Lake Oswego. The citizens in Lake Oswego would not accept drinking treated Willamette River water although the river is adjacent to the city. However, they did approve Clackamas River water as their primary source. It is probable that if and when water becomes unavail- able from the Clackamas River, Willamette River water will be used. Portland, too, appears to have adopted a similar course of action. Land has been purchased near Corbett (Blue Lake) for a treatment plant to filter Bull Run water. At the same time, they are testing deep wells along the Columbia River to be used to supplement the Bull Run supply. If the wells do not produce, they can always use treated ,ft,,. Columbia River water during peak demand periods. Wolf Creek Highway Water District has been drilling test wells on Sauvie Island. If successful and economically feasible, the water will be filtered and pumped over the hill to their district. In any event there appears to be ample ground water near major rivers. Therefore, an optimistic view can be taken that well water will be available in the Wilsonville area. A course of action for the Tigard Water District, using first, well water, and finally, Willamette River water, if acceptable, would appear to be in our best interests. If we worked steadily toward a definitive goal, such as described, year after year, I believe it could be accomplished. About 1980 a bond issue could be requested to purchase land for a future treatment plant near Dammasch Hospital. Wells would be drilled on this site and a 36-inch transmission main constructed to the terminal reservoir on Bull Mountain. Estimated costs are shown as follows: -9- Nor ADMINISTRATOR'S REPORT (Continued) 40 acres of land @ $5,000 per acre $ 200,000 Drill 4 wells @ $50,000 each 200,000 36-inch transmission main -- 8 miles or 42,240 feet @ $90 per foot 3,800,000 Pump Station 200,000 1980: Total: $ 4,400,000 In 1984 another bond issue would be requested to construct a treatment plant to filter and soften the well water. Estimated costs 1984: Total: $ 5,000,000 Nor Finally, if and when the Willamette River water is acceptable to the patrons, the water intake and main extension to the river would complete the project. Estimated cost: 1988: Total: $ 1,000,000 or later This plan would appear to meet the immediate as well as long range needs of the district. Further, the financial burder of $10.4 million, spread over a 12 year period, could be fully assumed by the Tigard Water District if others did not desire to participate. If the Board of Commissioners adopted such a concept for future water supply, the staff could direct its efforts toward achieving that goal, and not waste time and effort in attempting to find other new sources of water. Efforts would be directed toward obtaining right- of-ways for the pipe line, selection of an appropriate site for the treatment plant, etc. wow -10- 'Noe ADMINISTRATOR'S REPORT (Continued) Such a concept would have an immediate effect upon the recent $1.9 million bond issue in that the design of the main along S. W. Gaarde Street, Pacific Highway to 121st Avenue, would be 36-inch in lieu of 16-inch in diameter. Approval of this concept would be of material assistance to other water districts and cities who are searching for partners in the development of new water sources. This act would not leave them in abeyance wondering, and perhaps hoping, that Tigard Water District might participate in a project with them. Consultation and coordina- tion with the Cities of Tualatin and Wilsonville, particularly the latter, should commence at an early date. Metzger Water District should also be invited to participate. However, in my judgment, the possibilities of the patrons of the Metzger Water District ever accepting anything but Bull Run water are extremely remote. Their fanatical belief that Bull Run is the "only" water, at any price, will prevent their Board of Commissioners from considering any other source of supply. Since Bull Run is the only acceptable water it would appear in their best interests to con- sider as an alternative, annexation to the City of Portland, just as other water districts are doing, including Capitol Highway Water Dis- trict and Powell Valley Highway Water District. "If you can't beat ' em, join ' em." We are indeed fortunate to have patrons who are not spoiled and have not been overwhelmed by the myth of the quality of Bull Run water. This is not to infer that Bull Run is not excellent. Finally, if adopted, the plan would provide guidance and direc- tion when negotiating with both Portland and Lake Oswego about long- term contracts, water rates, etc. Recommendation 3: That Tigard Water District approve the concept for future water supply as described above. -11- ADMINISTRATOR'S REPORT (Continued) 12.
