Resolution to assume difference in cost between 850 feet of 8-inch versus 12-inch pipe installation for Southwest Church of Christ an other single family home owners located on 98th Avenue. Summerfield Drive to Durham Road. The Southwest Church of Christ intends to participate with other existing home owners along S. W. 98th Avenue in the construction of a main to Durham Road. The master plan provides for a 12-inch main to be installed on this road. This installation, along with a proposed pipe extension along Durham Road, from 98th to 92nd, will correct the most deficient part of the distribution system. When completed, an important circulation loop will be provided, and Tigard High School will be served from two different directions with significantly better "fir fire flows. In the past, the Board has approved paying the difference in cost between 12-inch and 6-inch main installations for existing single family dwellings. Approval is recommended in this case. 5. Resolution to annex 324 acres of land located west of 122nd Avenue, south of Scholls Ferry Road. A question arose at the last meeting about the district's policy on annexation of property. A majority of the Board has always favored a policy of 1007. voluntary participation of the property owners. On occasion, this was not possible because some property owners would not agree to annex even though they were being served by the water district. Accordingly, they were annexed by "resolution" of the Board. It was not until about 4 years ago when the Boundary Review Commission was formed that such a method of annexation became legal. In addition to annexation by resolution, the law provides for petition methods of annexation, as follows: a. 107. of registered voters. b. 1/2 the land owners. c. Triple majority -- Majority of landowners who own at least a majority of the land which constitutes at least a majority of the assessed value. -1- ADMINISTRATOR'S REPORT (Continued) During my 6 years here I have attempted to establish the district's boundaries so that the water sytem can be designed to serve the potential service area. Most islands have been absorbed into the district, and all boundaries, except on the west side, are well-defined. Except for those customers served in the Metzger Water District, only one patron is being served out-of-district. Mrs. Leah Zednick is provided water service, but the Boundary Review Commission will not approve annexation of either her property or the island north of Bull Mountain of which her property is a part. It would be unfortunate to return to the single lot by lot annexa- tion procedure. A considerable amount of work and effort goes into each annexation proposal, no matter which method is used. Acquiring signatures is just a small part of the problem. Someone has to prepare legal descrip- tions, determine assessed valuations, obtain a list of all owners, complete questionaires, obtain maps, and finally, appear before the Boundary Review Commission. For this reason, and the fact that, in most cases, the next door neighbor will eventually agree to annex, I have favored area annexations. It reduces the every day workload for administrative personnel. Previously, almost all new meter applications required a petition to annex the property. Annexations are now reviewed annually by the Board of Commissioners versus a monthly basis previously. Finally, the additional tax base certainly helps in sharing the cost of bonded indebtedness. Assessed valuation of the district during the past NNW 8 years is shown as follows: Year Assessed Valuation 1968-69 $ 61,900,000 1969-70 80,100,000 1970-71 96,700,000 1971-72 111,400,000 1972-73 135,854,000 1973-74 157,037,000 1974-75 194,780,000 1975-76 235,960,000 Some of this increase in valuation is due to inflation, but most is a result of a vigorous campaign to annex those properties being served or capable of being served. The property considered for annexation at this time consists of 324 acres located south of Scholls Ferry Road, west of 122nd Avenue, valued at $885,700. (See enclosed map). It includes the former Stark airfield. Mr. Stark's well became polluted and the district is now serving his house on a temporary basis. The tally, at this date, shows 13 in favor and 4 against annexation. -2- ADMINISTRATOR'S REPORT (Continued) """" 6. Discussion of Meter Connection Charges. At the last meeting the Board requested the submission of a proposed schedule of single dwelling equivalencies to be used in determining charges for multiple dwellings or meter installations larger than 3/4-inch, using as a guideline the equivalencies established by United Sewerage Agency and Wolf Creek Highway Water District. The subject of meter connection charges has been discussed in past meetings with considerable differences of opinion as to fairness. Apparently, all retail water purveyors have the same problem, resulting in a wide variation in costs of meter installa- tions and connection charges. In accordance with your request, enclosed with this document is a report prepared to provide information on the legality, fair- ness, and appropriateness of meter connection charges. 7. Discussion to request voter approval on September 21, 1976, to issue General Obligation Bonds totalling $10 million to develop .,y the Willamette River at Wilsonville as a source of water. A bond election for $1.7 million has been approved for May 25, 1976, to construct a 10-million gallon reservoir and appropriate transmission mains. This will solve the water storage problems of the district until about 1990. I believe the water source bond issue should be on a separate ballot at a later date. It is recommended that September 21, 1976 be the election date for a water source on the Willamette River. This will provide a few extra months to finish conducting water quality and temperature tests and obtaining firm commitments from other water purveyors on participation. State of Oregon election dates have been set for May 25, June 29, August 10, September 21, and November 2, 1976. At the last meeting the Board requested that I prepare alterna- tives, and a recommended method and schedule of payments to liquidate the proposed G.O. Bond issue for development of the Willamette River. First, it would be appropriate to discuss funding of the $1.7 million bond issue for construction of the terminal reservoir. About $170,000 additional revenue will be needed annually to handle this debt. It is proposed that neither the tax rate nor consumer user rates lbw be increased for this bond issue. To acquire these funds, possible sources of revenue are listed as follows: -3- ADMINISTRATOR'S REPORT (Continued) a. Increased meter connection charges. (See below) $ 50,000 b. With voter approval at the bond election, do not refund or reduce the existing consumer rates, although it appears Lake Oswego will lose the lawsuit and will be obligated to negotiate with TWD on the wholesale rate of water 30,000 c. In 1979-80, the bond issue of 1959 will be fully paid off 12,000 d. Increased revenue from volume water sales 24,000 e. Increased tax revenue due to increased assessed valuation of real property 18,000 f. Reduction in pipe replacement and extension program 36,000 Total: $iLla(� Meter connection charges will be increased on January 1, 1976. Approximately $25,000 additional revenue will be generated from this source. Based upon the study on meter charges contained herein it is proposed that meter connection fees be increased again on July 1, New1976, to include Portland's system development charge, as follows: Jan. 1, 1976 Proposed Size of Meter Charge Charge* % Increase 5/8" x 3/4" $ 450 $ 500 117. 1" 550 800 45% 111" 1,200 2,000 677. 2" 1,400 3,000 1147. 3" 3,000 6,000 100% 4" 5,000 10,000 100% 6" 6,000 18,000 200% 8" 7,000 28,000 300% * The total multiple of flow rate is not used to the maximum extent because there is some advantage to the water district in servicing only one large meter versus many smaller meters.

It does appear, at this time, that the bonded indebtedness for the $1.7 million can be funded without either a tax rate or consumer rate increase. This will be an important point in selling the program to the public. The bonded indebtedness for development of the Willamette River is a different story. The SUR study of July 15, 1975 indicated that $8.23 million, based on 1974 dollars, would be necessary to develop this source of water for the three entities of Wilsonville, Tualatin, and Tigard Water District. For planning purposes, a figure of $10 million can be used. Metzger Water District has expressed some interest in this source of water. If they are included, additional facilities will be necessary, and an estimated cost of $13 million will be required. The 1st National Bank has provided some proposed maturity schedules for $6.6 million and $10.6 million bond issues at 6.57. and 7.07. interest. (See enclosed documents). Any participation by TWD will require substantial increases in both the tax rate and consumer user rates. This will be particularly critical during the first few years during the period of construction. Water will still have to be purchased from either Lake Oswego or Port- land, but payments will have to be made on the bonded indebtedness at the same time. The Boundary Review Commission has stated that they will not accept the formation of another layer of government to develop the Willamette River. Therefore, such a venture with other participants would have to be in some form of a partnership. An executive board, with representation from each entity, based on dollar investment, might be one way to organize and govern operations of the treatment plant. Of course, the question arises as to "fair" share of the total cost of the project. As a start, I have made some computations using the eight different combinations of possible participants: Tigard, Metzger, Tualatin, and Wilsonville. Equal weight was given to the following potential sources of revenue as of July 1, 1975: a. Assessed valuation b. Water consumption c. Meter connections Now' It is emphasized that exact participation will have to be negotiated by all parties and this is not intended to be the final solution. -5- ADMINISTRATOR'S REPORT (Continued) Combinations of participants.

This added burden eventually results in the need for increased reservoir capacity, larger transmission mains, more pump stations, additional treatment plant facilities, etc. However, the entire burden cannot be placed upon new connections because part of the higher water consumption is due to increased water use by individuals already on the system. A municipal water system requires "x" number of dollars to operate and remain solvent. Obviously, meter connection charges must bear a part of the burden. It is a matter of opinion and judgment of the govern- ing body to determine how much of the total cost of the system should be borne by meter connection charges. Federal and State laws prescribe, and the courts have ruled, that charges must be reasonable, and not arbitrary, capricious, or discrimina- vow tory. Most water purveyors utilize meters to determine the quantity of water consumed. Meters are rated by safe operating capacity (gallons per minute) as shown below: Size of Meter Safe Operating Capacity 5/8" x 3/4" (standard) 20 GPM 1" 50 GPM 111" 100 GPM 2" 160 GPM 3" 320 GPM 4" 500 GPM 6" 1000 GPM 8" 1600 GPM Nur -1- METER CONNECTION CHARGES (Continued) Thus, if one knows the anticipated capacity of a potential user, a meter can be sized properly. It would seem to be a relatively simple task to determine the number and types of water fixture units and convert those figures to flow rate (gallons per minute) which, in turn, reflects the correct meter size. The validity of this concept will be discussed later, but, first, a review of a few other methods of determining meter connection charges will be presented. a. Charges per dwelling unit. One of the most common methods of charging for meter connections is based upon the number of "dwelling units". For examples a 100-unit apartment, utilizing one large meter, should be charged 100 times some arbitrary unit dollar amount. This is often compared to the single Aar family dwelling. It is an effort to offset the apparent inequity in charges because 100 individual meters were not installed. The "per unit" charge is supposed to correct this deficiency. Many persons believe that apartment owners do not pay a high enough proportion of the total cost of the water system. Therefore, a charge "per unit" is considered justified. The courts have ruled that such charges are arbitrary and capricious. (See attached Circuit Court of Oregon case, dated March 15, 1973, Franklin Service Corporation vs Progress Water District). In my judgment, the charges are also discriminatory. Why does a water purveyor single out only the multiple dwelling owner? One must realize that the construction of an apartment house is a commercial venture, no different from a bank, shopping center, car wash, hospital, etc. -2- METER CONNECTION CHARGES (Continued) To initiate or continue utilizing this method to gain additional revenue, solely at the expense of the apartment owner, is obviously illegal. In this regard, I am firmly convinced that that portion of Portland's system development charge, based upon a "per unit" schedule is clearly illegal and can be challenged in court. b. Charges per equivalent dwelling unit. Another method of computing charges for meter connections is based on "equivalent dwelling units". It is an attempt to equate large water consumers to a number of single family dwellings. This method is cer- tainly an improvement upon the "per dwelling unit" charge which is applicable only to apartment owners. It has been challenged in court and held to be valid. (See attached Circuit Court of Oregon case, dated October 28, 1974, Dave Christensen Inc. , vs Wolf Creek Highway Water District). The objection to this method is the apparent injustice in establish- ing criteria for "equivalent dwelling units". For example: Wolf Creek's schedule equates 2.5 hospital beds or 25 pews in a church to 1 single family dwelling. This is an opinion and certainly there are no facts to support this conclusion. The equivalent dwelling units are arbitrarily established and may or may not have a bearing on potential water demand. This causes a purchaser of a meter to question the validity of the charges. While Wolf Creek's schedule was held to be justified in court, I believe there is a better way to obtain fairness in meter connection charges, but, at the same time, receive a just monetary return for the demand placed upon the water system. In the case of the United Sewerage Agency, sewer water is not metered, therefore, their system of charges based upon "equivalent dwelling units" appears to be their only solution and fully justifiable. They also use a schedule of water fixture units (equivalents) for commercial buildings and laundromats. (Enclosed are copies of the schedules and charges for U.S.A. and Wolf Creek Highway Water District). -3- METER CONNECTION CHARGES (Continued) r.. c. Charges per equivalent fixture units. Meter installations must bear a fair share of the total financial burden of the water system. It would appear that the relative cost of a meter installation should be based upon how much the system is taxed by that particular meter connection. Mechanical means (the meter) are available to measure accurately the amount of that potential demand upon the system. Knowing the anticipated capacity (gallons per minute), the correct meter size can easily be determined. Therefore, it would seem logical that meter size should dictate the charge for a meter connection. For example: a 2-inch meter has a flow rate capacity of 8 times that of a standard 5/8" x 3/4" meter. Therefore, it would not be unreasonable to charge 8 times the cost of a standard meter installation. The potential flow rate taxes the system, ,not the number of apartments or equivalent dwelling units. NNW Applying the multiple factors based on flow rate of the standard meter would result in meter charges as shown below: (Also shown as a comparison are Portland's per unit charges for multiple dwellings).

Engineering data are available to verify the potential water consumption. Meters can be flow tested for accuracy and reliability if a doubt should occur. The paramount issue here is to determine the correct meter size which is dependent upon the flow rate (gallons per minute) required by the water facilities located within a building. Again, engineers (American Society of Mechanical Engineers, ASME) have come to the rescue with a schedule of "equivalent fixture units". Attached is a copy of such a schedule based upon "fixture units". For example: a private bathtub uses 2 "fixture units"; a water closet uses 3 "fixture units", etc. The sum of the number of fixture units of a building is used in establishing the demand (gallons per minute) upon the system as shown on Graphs I and II. Simply stated, the procedure is as follows: a. Calculate the total number of (water) fixture units. b. Extract from the graph the demand (gallons per minute). c. The "gallons per minute" dictate the meter size. In conclusion, most would agree that the potential large users, including apartment owners, are not paying their proportionate fair share of the financial burden. This can be corrected by charging substantially higher amounts to all potential users for the connection of the larger meters. In this manner, apartment owners and other types of commercial enterprises who are capable of consuming large volumes of water are all charged a like amount, based solely on potential water demand. %I// December 2, 1975 Robert E.
