Co. Tax Map 1S1 34DA, Tax Lot 2600) . The matter is to be reviewed by Council on appeal by the applicant pursuant to Section 18.84.250 (b) (1) .

During Council consideration, Council may pose questions to staff and parties on policy issues. (a) Legal Counsel advised Council that whatever decision is made tonight should be tentative and that a final order will be prepared for adoption at the next meeting. (b) Councilor Cook questioned Legal Counsel as to what action Council can take at this time. Legal Counsel responded that Council has the right to amend the request, deny it, or approve it. He cautioned Council to only pose policy questions to the applicant or staff since this is not a fact-finding hearing since they are included in the record. (c) Councilor Cook stated if lots 8 - 18 were eliminated from the plat, he could then approve the subdivision request. He expressed concern with placing homes on fill in the floodplain. Councilor Stimler stated that Planning Commission took an appropriate action by denying the application due to the amount of fill being used. She could only support building in the area if the excess fill were taken out of the floodplain area.

(f) Legal Counsel stated a final order would be prepared noting the application must have minimal, if any, intrusion into the floodplain. PUBLIC HEARING PORTION OF MEETING CONCLUDED 22. WATER REPORT (a) City Administrator reported that in October of 1981 Council had a goal-setting retreat and at that time suggested that the City study the water service in the City and look at taking over that function in accordance with state law. Following that, at the November 23, 1981 Council meeting, there was a goal setting time with all boards, commissions, and the water district along with the fire district representatives. the water study was placed as a medium priority with fees and charges placed highest on the action list by Council. He went on to advise that the Chamber of Commerce has now exprssed some concern regarding this issue and thus the City on 5/5/82 contracted with Lee Engineering to conduct a preliminary study of the district. The Administrator stated that he in no way wanted to be critical of the district, felt there had been good operations up to this point and wanted to cooperate 100% with the district, however, felt that there needed to be a study done of the long range wager needs and the cost of that service. He felt that the engineer's report should be done by a third party and thus contracted with Lee Engineering to complete. (b) Duane Lee, President of Lee, Engineering, Inc. , presented a draft of the analysis of the Tigard Water District. He stated the report had been completed in less than three weeks and thus may have some areas which need improvement. He discussed the summary of the report and showed slides of the .Tigard Water District's tanks and equipment, water technology and other water treatment plants in the area. Walt Menuskee, Lee Engineering Inc. , discussed the water district financial standing, rates, history of water availability and projected needs and availability. He concluded by drawing Council's attention to the report and the conclusion that for the short term, the Tigard Water District can continue to buy water at the lowest price from anyone who is willing to sell surplus water. But in the long term, the District must turn more and more to other alternative supplies of water. (See attached draft copy of "Analysis of the Tigard Water District for City of Tigard" report.) (c) City Administrator stated this presents some policy issues that the Council and the community needs to deal with.

(d) Bob Santee, Superintendent of the Tigard Water District, appeared before the Council with many of his Board members present to discuss the report as prepared by Lee Engineering.

He noted that the Board of Commissioners for the District have been looking carefully at the long range needs for the district and have recently signed with the City of Portland a 25 year contract. He expressed the District's desire to use a combination of different water sources so as to not "put all the eggs in one basket." (e) After discussion regarding the Portland contract, consensus of Council was to have Lee Engineering do a final draft of the analysis report and present it to Council .on June 14, 1982.

Since we are already overloaded at the clerical level, I wanted to refill this impor- tant position without delay. A former Administrative Secretary of mine heard of the opening and applied. Since we opened the position internally just six months ago, there have been no signficiant changes in the skills of current staff, and since the Executive Secretary position is exempt from our union contracts, I recommend waiver of Section 2.2 of the Personnel Rules on job announcement by motion of Council. With the Council's waiver, I will hire Mrs. Dori Rickert as of June 1, 1982. Y rs uly, Robe t W.

MuIIh�01 County Administrator Subject NON-CITY/CITY SUBSIDY MAY = At the Public Officials ' Caucas 'of May 6, 1982, it was decided to discuss with Portland State University officials their ability to professionally examine the issue of. whether a non-city or city subsidy exists in Washington County. The procedure that we have established to begin examining this issue will be to first sit down th Portland State officials and discuss the scope and breadth of County government in Washington County. This meeting has been set up for May 20, 1982 at 9:00 a.m. and in attendance will be Marge Post, Don Mason, Bruce Thomson, and myself. This meeting will review County programs, the cost of those programs, and how the programs are financed. In addition, the Portland State researchers will have the opportunity to question us about the services the County renders . The next step in this procedure will be to discuss this issue with the City Managers of Washington County. Bob Jean is arranging a meeting for early June. The purpose of this meeting will be to examine County services, the cost of those services and which County services should be the subject of extensive research. Both of these meetings will be very important in determining any financial costs of a study on this issue. It will also begin to identify the method and scope of such a project. Once the method and scope has been identified, then the County and other officials can determine how they wish to proceed in this matter. This information is intended to keep you current about the proceedings in this matter.

The Commission also recommended two rate adjust- ments to include a sewer service charge increase of $0. 75 per unit per month and a $50 per equivalent unit increase in connection fees. These adjustments are less than those provided in our long term financial plan but will help in moving us toward that plan's objectives. You should plan for these rate adjustments in your budget process. The Budget Committee has set the Budget Hearing for May 20, 1982 at 3 p.m. at the Rock Creek Facility. cerely, kl Wi -y44 f, Gary F.

BOX 222 LAKE 05vYGG0, OREGON ZIP CODE 97034 AREA CODE 803 - 635-4530 On September 8, 1981, THE PLANNING COMMISSION approved a CO�II'REHENSIVE PI,"N REVISION and PRELIMINARY PLAN REVIEW of the site for MANUFACTURED HOUSING. - We applied for a GENERAL PLAN REVIEW on January 30, 1982, and THE PLANNING STAFF requested an application for a SENSITIVE LANDS PERMIT to allow filing within the 100-year floodplan. Bruce Kamhoot & Associates, Inc. hired Mr. James F. Nims (a registered engineer) to study the problem and offer a solu- tion. This solution is indicated by attached documents. The recommendation made by Mr. Nims was approved and recowmended by the PLANNING COMMISSION STAFF and concurred in by the U. S. ARMY CORPS OF ENGINEERS. At the April 6th meet- ing, the complaints of the neighbors regarding the presence of a Manufactured Home Subdivision seemed to be the predominent area of discussion rather than regarding the sensitive land use. WE PROPOSE TO THE HONORABLE MAYOR AND CITY COUNCIL OF THE CITY OF TIGARD that a decision regarding a Manufactured Housing Subdivision in the area has been addressed at previous meetings and approved and that the PLANNING COUNCIL during the April 6th meeting did not address the issue, at hand, and as a consequence they made a decision, that was total reverse of their previous decision. The proponents of this proposal contend that there is a need in the City of Tigard for moderate priced housing that can only be provided by Manufactured Housing and still meet the requirements of the building department providing safe affordable shelter for the first time home buyer, in accordance with the general guide line of L.C.D.C. This land is in the ownership of the UNIFIED SEWER DISTRICT and with the advent of the Durham plant it became of no further use to the district. Since this property was previously zoned LIGHT INDUSTRIAL by Washington County, and with the current acquiesce of the U. S. ARMY CORPS OF ENGINEERS, it could have been used for industrial purposes. THE UNIFIED SEWER DISTRICT and the CITY OF TIGARD PLANNING STAFF believe that a MANUFACTURED HOUSING SUBDIVISION is i a better neighborhood use than INDUSTRIAL, and we wish to submit, that had z CONSTRUCTION PROPERTY DEVELOPMENT CONSULTING BRUCE= KAfv1HOOT Sc ASSOCIATES, INC. BOX 222 i—AKE OSWEGO, OREGON ZIP COOE 07034 AREA CODE 303 — 035-4650 this property been developed Industrially, this action would have tended to devaluate the housing in the immediate vacinity. A MANUFACTURED HOUS- ING SUBDIVISION where the houses are set at ground level and are accom- panied by garages or carports will tend not to devaluate the neighborhood, in fact, will tend to make a better community by removing the remains of the FORMER SEWER PLANT. We hereby request the council to evaluate and give careful consideration to the proposal. CONSTRUCTION PROPERTY DEVELOPMENT CONSULTING i s 100 YEA1,' I-1.00D PLAIN This project is located within the City of and a portion of the improvements .11-0 within the 100 yctir flc��).i plain, of Fanno Creek . The projrrt is south of S .1%,. 5ihoIIS Ferry Road , and North of S .W. North Dakota. Reference will be matte to the Study made by Ch2M Hill of 1981 for the City of Ti,,zii-d , for informational purposes . The first reference is made to Page 4-6, showing the width of the Flood plain varies fuom 250 feet to 900 feet, as shown in the attachments . . Specifically this site is the abandoned Metzger Sewage Treatment facility. A housing project just downstream or south of thy - proposal encroached into the floodplain area approximately six times the area factor, as show4on sheet Washington County Flood Plain ;`lap, Zone "13' as the encroachment that is proposed . . Some of the areas- that will be addressed are as outlined on page 3-11 , Guidelines , as follows . 1 . The owner accepts any and all liability for removal of earth as a part of the construction together with the placement: of riprap in new embankment areas . 2. The Natural drainage area is not. to be substantially altered however, by the excavation of some earth the flow should be improved, as it will be removed to make a less restri-etive channel: . See the attached drawing showing the distances as marked . 3 . A velocity of 6 f . p.S . should be antisipated if the current constrictions are removed . l:iprap is designed for this flog,; velocity, which requires a 5" size stone . See sheet 5-1 Reference is nizido to Figure 5 . 3 to shot. they m:i-Xi.murn flot,' at North Dakota of 2700 C. F. S . , (:urrently and an ultimnte flow of 3450 C. F. S . Therefore , %•.ihere new embankments are to be construg•tod within the flood plain , bank protection will be constructed as shown on Figure 6-1 . My conclusion is after reading the study that boc•ause the mn jor constrictions are located in relative small oponnings both upstroam and downstream, and if major floods occur that water will flew over the tops of both reads , that the filling of s*stall area such as we discussing will have little or no effect to either- velocity or storage of water, as long as the embankment area quantity is not exceeded by the amount of excavation taken from the flood plain under Elevation 160. I might acid the removal of constrictions are recommended on Page 6-3, and are described as "creating Flooding Problems" &me . Nims .E.

The flood elevation over the North Dakota St. bridge is projected to be 2 .2 feet higher than the road surface. Both the Tigard St. and North Dakota St- bridges would have a high probability of losing their spans if a fl,-,o_:1 r of this magnitude did occur. " North Dakota - St. to Scholls Ferry Rd. The flooding problems r along this reach of Fanno Creek are relatively minor because development has been restricted in the flood plain. A few residential structures on Ironwood Loop may experience minor C damage during the 100-year flood. The flood-plain width along this reach of the stream varies from 250 to 950 feet. The flood elevation at the upstream face of the existing Scholls Ferry Rd. bridge is projected to be 0 .7 foot lower than the road surface over the bridge. However, floodwaters will be E approximately 0 .3 foot deep over a low spot on Scholls Ferry Rd. located about 125 feet northeast of the east bridge abutment. The Scholls Ferry Rd. bridge is scheduled to be replaced in the near future by the Oregon Highway Department. The flood-related effects of the new structure will be discussed in Chapter 5 of this report. Scholls Ferry Rd. to 200 Feet Downstream of Hall Blvd. (Beaverton) . The flooding problems along this reach of Fanno s Creek are relatively minor. The flood-plain width varies from 400 to ' 1, 900 feet. A few houses along both Settler Way and Parkview Loop may experience minor damage during the 100-year flood. A potential off-line storage reservoir site exists on the east overbank of Fanno Creek approximately 0 .8 mile upstream of the Scholls Ferry Rd. bridge. 4. 1 . 1.2 Ash Creek Ash Creek is a major tributary of Fanno Creek, and it enters Fanno from the east approximately 400 Feet upstream of North Dakota St. Ash Creek drains a 4.1-square-mile area that is predominantly residential in land use. As part of the Washington County FIS, the COE computed flood elevations along a 1 .5-mile reach of Ash Creek from its mouth to Hemlock Street. ; Flood-plain maps were also drawn by the COE for the 100-year flood along Ash Creek. The maps show that some flood damage would occur along Ash Creek: if the 100-year flood occurred. The following is a detailed description of the 100-year flooding problems along Ash Creek. f Mouth to Highway 217 . The flood-plain width along this reach of Ash Creek varies from 100 to 900 feet with the greater widths occurring downstream or to. Rd. An industrial building located on the southeast overbank of the creek between the Southern Pacific Railroad and Greenbur,: Rd. may suffer some minor damage. One residential structure appears to be within the 100-year flood plain. It is located on the 274D 4-6 6 . 1 .4 Storage Effect Using the future 100-year flood hydrograph just upstream of Scholls Ferry Rd. obtained from the Fanno Creek model, the storage provided in the detention facility described above could conceivably lower the future 100-year flood peak from 2,580 to 2, 000 cfs. This represents a 29 percent reduction in the peak at the storage facility. The Fanno Creek hydro- logical model was then used to estimate the future 100-year peaks farther downstream of the potential storage facility. These lower peak flows were then added into the Fanno Creek hydraulic model to estimate the reduction in floodwater elevations throughout Tigard that would result from the potential storage facility. Figure 6.1 shows the future 100-year flood elevations along Fanno Creek, both with and without the storage facility. All the bridges in Figure 6.1 are existing structures except the Scholls Ferry Rd. bridge, which is the proposed state ! highway structure discussed in Chapter 5. r Figure 6.1 shows that the flood stage reduction is approxi- mately 2 feet just below the proposed facility (not shown but located between Sections 7 .81 and 8 .03 ) . However, the flood stage reduction decreases to approximately 1.5 feet i just below Scholls Ferry Rd. and to approximately 0. 5 foot below Tigard St. and throughout most of downtown Tigard: Although the flood peak reduction was 29 percent at the facility, its effect decreases substantially once Ash and Summer Creeks enter Fanno Creek. In fact, the potential storage facility will provide only a 5.4 percent reduction in the peak flow at Main St. The potential storage facility does not appear to be an effective flood control alternative by itself. However, it may provide more benefit in conjunction with the selective removal and reconstruction of bridges and other hydraulic constrictions farther downstream. 6 .2 CONSTRICTION REMOVAL Figure 6. 1 shows that several road crossings on Fanno Creek are creating flooding problems because they constrict the amouit of flow area available to the floodwaters _ These structures include: Bonita Rd. , Hall Blvd. , .lain St. , Grant Ave. , Tiedeman Ave. , Tigard St. , and Ndrth Dakota St. In addition to the constrictions created by these structures, channel constrictions occur in the vicinity of the Main St. bridge and the Grant Ave. bridge. Also, the streambed profile shown on Figure 6.1 indicates that considerable scour and deposition have occurred in the immediate vicinity of these two structures . 464CC 6-3 6 . 1 .4 Storage Effect Using the future 100-year flood hydrograph just upstream or Scholls Ferry Rd. obtained from the Fanno Creek model, the storage provided in the detention facility described above could conceivably lower the future 100-year flood peak from 2, 580 to 2, 000 cfs .

Riprap of rock, rubble masonry with grout, sacked concrete, and broken concrete slab are most commonly used to protect embankment or channel slopes of unstable material . -.02.00 Rock Riprap Rock riprap is either light loose or heavy loose riprap. Either should be placed on a one-foot thick filter material graded from sand to- 6 inch gravel to protect the original bank material from scour or sloughing. The filter should be graded in layers from fine to coarse out to' theriprap. Riprap thickness should be 2 feet thick for light loose and 3 feet thick for heavy loose riprap. The toe of the riprap should be placed below the channel bed a depth equal to the thickness of the riprap. • O - OD= /00 qq flood deofh or Q o� Tyoica/ Roc1r R,orpp Fig. 6-1 6-2 DRAINAGE CRITERIA MANUAL MAJOR DRAINAGE 4� NOTE )�-I The rlprop should be composed of 5000 wen graded mixture but most of 'iI f�T the stones should be of the size I Indicated by the curve Rlprop should I !

RIPRAP SIZING (13) 12 - 15 - 68 03nvar Rvgionol Council of Govarnmanla artificial channels will be used with discretion and then only to accommodate existing development for minimum reaches _ Channel design criteria include: o Channel side slopes from 2 : 1 to 1'x: 1 may be rip- rapped, but steeper slopes must be solidly lined with an anchored wall. Care must be taken for freeze, thaw, ground-water, and expansive soil effects- 0 The bottom of channels must generally be lined when the velocity exceeds 6 fps . ® The channel should have a freeboard of 2 feet. • -' A Use trickle channels for low flows with capacities of about 1 percent of design flow. Natural Channels. Natural waterways in urbanized and urbaniz- able areas that have mild slopes, are reasonably stabilized, and obviously are not in a state of degradation may not need extensive modification for them to provide adequate service as part of the drainage system. If the channel is to be used for carrying storm runoff from the urbanized area, it can be initially assumed that the changed runoff regime will result in new and active erosional tendencies . In some cases, slight modifications to the channel will be required to create a ' more stabilized -condition for the channel . Because of the decided sociological advantages of using natural .waterways for urban storm drainage purposes, the designer should consult with experts in related fields about the method of development. Usually, park and greenbelt areas can be incorporated into the channel works . In these cases, criteria for freeboard depth, curvature, and other design aspects applicable to artificial channels do not apply. For instance, there may be significant advantages 'Co designing adjacent areas for localized flooding during major runoff peaks. In addition, the flood plain must be defined so I adequate land use zoning will protect the waterway from encroachment and allow it to maintain its capacity and natural storage potential. Channel Erosion Control . Grass-lined channels are erodible to some degree. Experience has shown that designing a grass- lined channel completely protected from erosion is uneconomi- cal and costly. It is much better to provide a reasonable design with plans for additional erosion control measures and corrective steps after the first year of operation. Using erosion control cutoff walls will safeguard a channel from serious erosion in case of a large runoff before the grass can develop a good root system. Such cutoff walls are also useful in containing the trickle channel . 274E 5•-17 MASTER DRAINAGE PLAN�� VT FIGURE 5.3 CITY O; TIGARD } -►--r-- .

Based on a review of current audits, the fiscal condition of the Water District also appears to be very goods The present water supply for the District appears to be adequate, but the District has not yet committed to a long-term supply of water and this lack of commitment may have significant impact on the future growth potential of the City of Tigard. A summary of the major findings resulting from this report is as follows: 1. Supply and Distribution Pipelines The condition of the present supply and distribution system is good to very good. The pipelines are constructed of primarily ductile iron and cast iron pipes which are considered to be' one of the better construction materials for water lines. The pipes have been sized adequately to meet present and future water distribution requirements. Most of the pipelines are located within public rights-of-way and are adequately valved for routine operation and maintenance. Other construction materials such as fire hydrants, service lines, and meters are of good to excellent quality and have been installed, for the most part, during the past 15 to 20 years. Most of the materials for construction can be expected to last between 20 and 200 years. Water meters will need to be tested and replaced every 20 to ARM 40 years; service lines every 40 to 60 years; and pipelines every 100 to 200 years. In general., the materials of construction used in the distribution system together with services are those commonly used in the waterworks industry and there appear to be no major deficiencies in the piping system of the Tigard Water District. 2. Storage The c-tnrage facilities of the District consist of steel and concr e"Ce reservoirs totalling 17.4 mg capacity at this time. An additional 2.5 mg capacity is being constructed. The reservoirs are in good to very good condition. An original study done in 1971 by Stevens, Thompson and Runyan, Inc. indicated a need for 20 mg of storage by the year 2000. The District has constructed the estimated required storage at this time, contem- plating the future need. However, based on more recent estimations for growth in Tigard, it appears that the 20 mg of storage will last beyond the year 2000. Only minor maintenance is anticipated in the reservoirs during the next 20 years. Those maintenance efforts will include repainting of the steel tanks, cleaning and possible coating of the interior of the -. concrete tanks, and repair of the exposed concrete on the roof and top of walls of some of the tanks. Each of these items are considered to be normal , routine maintenance. 1 3. Fire Protection The computer analysis developed for this brief investigation of the Tigard Water District indicates that fire protection is adequate throughout most areas within Tigard. Assuming that the District continues to construct the piping network proposed in the 1371 study, it appears that fire protection will be adequate throughout the Dis- trict through the year 2000, based on present requirements of the local fire districts and the Insurance Service Office (ISO). 4. Supply h�strict presently obtains the majority of its water from the City of Lake Oswego and uses additional water supplies from its wells and the City of Portland to assist meeting peak day demands each summer. The District does not have a committed source of water to meet its long-range needs. A decision on long-range water supply should be made in the very near future. Failure to commit to a long-range need will foreclose many of the present options that may be available. Failure to commit to a long-range supply may have serious consequences on the future growth of the City of Tigard. 5. Water Rates A comparison of water rates for the Tigard Water District in relation- ship to other water rates for neighboring communities indicates that Tigard's rates are slightly above average of those for the surrounding communities. The primary effect on future water rates will depend upon the future supply of water to the Tigard area. It is safe to say that future water rates will significantly increase as a result of the development of future water supplies. g�g E } 2 CHAPTER II INTRODUCTION 2.1 PURPOSE AND AUTHORIZATION The City of Tigard receives domestic water service from the Tigard and Metzger Water Districts. The Tigard Water District provides approximately 80% of the City's domestic water. The Water District purchases most of its water from Lake Oswego and also provides water from its own wells and from the City of Portland. The District does not own any interest in the water supply facilities of Lake Oswego or Portland. The District's primary function is to disribute water to its customers through a system of pumping stations, pipelines and reservoirs. The City of Tigard is separate from the Tigard Water District. Each entity is a municipal corporation established under Oregon law and each has its own elected officials to oversee the operation of each jurisdiction. Although the Water District serves areas outside the City, the City is concerned about the operation of the Water District since a large portion of the District includes the City of Tigard. The City is required by Oregon State law to include in its Comprehensive Planning process a review of the public facilities, including water and sewer service. The primary purpose of this study is to provide the City with an independent review of the water system to determine its ability to serve the present City and to serve the proposed future Comprehensive Plans for the City's growth. This study will also be used to further investigate other City facilities such as the City's sewer system. Obviously, there is a direct relationship between consumption of domestic water and the generation of sewage. A major concern of the City at this time is the apparent lack of cooperation between the City and the Dater District regarding each entity's planning efforts. There is also major concern regarding the future growth of Tigard and the apparent lack of an established or committed plan for a long-term supply of water to meet the present and future growth of Tigard. Therefore, Lee Engineering, Inc. was authorized by the City of Tigard in a letter dated May 5, 1982, to conduct a technical and financial analysis of the Water District to assist the City in determining how well the Water District serves the City. 2.2 SCOPE The scope of the study includes the following primary elements: 1. A review of the existing Water District, including a physical inventory of pipelines, pumping stations and reservoirs. The facilities were mathematically modeled and analyzed with the aid of a computer. The system was analyzed to determine the ability of the physical improve- ments to meet water demands including fire flows. 2. A projection of the future needs of the water system with regard to future land use, population and proposed improvements. H a 3 3. A review of the financial status of the District including a 'com- parison of residential rates with those of surrounding municipalities. 4. A brief assessment of the present and future water supplies. The scope of this study was limited to a review of the existing available data supplied by Tigard and other jurisdictions. No intent was made to develop new plans or to investigate in detail additional information which was not submitted directly to us. For example, no attempt was made to thoroughly investigate the detailed operations of the Water District; the investigation was limited primarily to results of past operations and information submitted to us. Cost estimates developed during analysis of al::ernative water supplies resulted from information taken from other reports. That information was updated to current costs where possible. Cost estimates were analyzed to the degree necessary to compare various alternatives. The cost estimates were not intended nor proported to represent the true costs which may result from development of future supplies. More detailed studies and cost estimates are necessary before any of the plans are implemented. 2.3 ACKNOWLEDGEMENTS The following individuals provided much of the data upon which this report is based.

Don Potter, Manager, City of Wilsonville: 4 CHAPTER III INVENTORY OF EXISTING CONDITIONS 3.1 BACKGROUND Thei�'gard Water District, organized in 1938 as a municipal corporation, provides water to the City of Tigard, King City and a portion of unincor- porated Washington County to the west of the two cities. Presently, two-thirds of its service area is within the city limits of Tigard. In addition, approximately 80% of the City of Tigard is served by the Tigard Water District and the remaining 20% in the northeastern portion of the City is served by the Metzger Water District. 3.2 WATER SUPPLY AND CONSUMPTION The Tigard Water District obtains water from three sources: 1. Four deep wells owned by the District. 2. Bull Run water via purchase from the City of Portland. 3. Clackamas River water via purchase from the City of Lake Oswego. From 1938, when the District was formed, until the mid-1960's, groundwater was the primary source of supply. However, because the District's four wells could not keep up with increased demand due to rapid population growth, interties were made with the Metzger Water District in 1962 and the Capitol Highway Water District (now part of the Portland Water Bureau) in 1969 to provide surplus Bull Run water. However, these interties proved unsatisfactory because the facilities of the two adjoining water districts were not designed to accommodate Tigard's demands as well as their own peak summer demands. Continued high consumption of groundwater from the Bull Mountain-Cooper Mountain basalt aquifer in which the District's wells are located led to a decline in the water table. Finally, in May 1974, the State Engineer declared the aquifer a "critical groundwater area" and imposed restric- tions on pumping. As a result, Tigard's wells are restricted to 1,060 acre feet per year or 46.2 million cubic feet per year which averages approximately .95 million gallons per day (mgd). As seen in Table 3.1, the production from the wells has never approached that limit but instead dropped to a low of 21 million cubic feet in 1978 due to a declining water tables. As a result, well no. 3 can produce no more than 50 gallons per minute (gpm). In addition, the iron content of well no. 4 has increased to the point where the well is no longer used. Therefore; only wells no. 1 and 2 are presently used. Together they produce 1 mgd and are only operated during the three or four-month summer period to aid in meeting peak demand. As a result of this and the growing demand, the percent of total water supplied by the wells has declined from 48% in 1973-74 to 14% in 1980-81. Therefore, the District can no longer depend on groundwater as a primary source of supply. 4 In 1973, direct connections were made to the Lake Oswego and Portland systems which have enabled the District to meet its supply needs through the purchase of surplus water. The City of Lake Oswego pumps Clackamas River water from its intake located in Gladstone through its 16 mgd water 5 treatment plant in West Linn up to its 4 mg Waluga Reservoir. From there the water flows through a dedicated 16" line to the District's 3,200 gpm Pump station near the intersection of I-5 and Bonita Road. The pump station is controlled from Lake Oswego's water treatment plant enabling the City to deliver surplus water on an "as needed - as available" basis. According to the City, the District calls the water treatment plant on a daily or weekly basis to determine if water is available and to request a specified amount to be purchased. This purchase arrangement was formalized by an agreement between the City and the District dated October 17, 1972, under which the City makes available surplus water to the District on the condition that the City reserves the right to interrupt or curtail delivery of that surplus water to the District. The agreement was effective for an initial period of four years and is automatically renewed for additional four-year periods unless terminated by the City at the end of any four- year period by giving at least one year's notice that insufficient water is available to meet the requirements of both the District and the City. The agreement may be terminated by the District at any time provided 60 days' notice is given. Since 1973, the District has relied on Lake Oswego as its primary source Of supply. The present cost of this water is $.31/100 cubic feet. As seen in Table 3.1, the percentage and amount of water purchased from Lake Oswego increased steadily between 1973 and 1978. During the period 1978 through 1980, water purchases were restricted and actually reduced by Lake Oswego because its system was reaching capacity. However, once the water treatment plant expansion from 10 to 16 mgd was completed and the capacity of the Waluga Reservoir was increased to 4 mg in late 1980, the restrictions were lifted and the District purchases increased. The increase appears much more dramatic between FY 79-80 and 80-81 because the District began supplying all of the City of Tualatin's water in May 1980. Prior to that date, Tualatin purchased water directly from Lake Oswego. However, due to Lake Oswego's increasing demand, that portion of its storage and distribution system near the Tualatin-Oswego intertie became inadequate to serve Tualatin's needs. The Tigard Water District purchases water from the City of Portland primarily-from March through September to satisfy excess demand that cannot be met by purchases from Lake Oswego or production from its wells. The Portland Water Bureau pumps Bull Run water from its Carolina and Fulton Pump stations through its Burlingame reservoir complex via a 24" main to Bradley Corners (the intersection of S.E. Oleson, Hall and Greenburg) where it passes through a 10" master meter and into the District's 16" trans- mission line. Water is supplied by Portland to the District under the terms of a 10-year agreement dated April 25, 1977, for the sale of a firm supply of surplus water. Under Article 3 of this agreement, Portland must supply an annual amount of water "computed as the prior year's consumption or the highest of the past three years, whichever is greater, plus an annual water con- sumption growth factor of 5%." The purchaser, however, may petition the City Council for approval of purchase of additional water. In addition, according to Article 11, the "Purchaser agrees to maintain its level of purchases ..... at not less than the present ratio of City water used to the total water used by the Purchaser based on the lower of the past three years' usage." 6 �A o r- LO r- OO to m rr to ...� r, -4 CT O N LC) Ln CU U H cm • • • • Cl C-D .4 N �--� N N N N N 7D W � r L w- Ln y • iV I C=) 3 O CT CD .-C Nr- � o ro LLJ 0 J to I.-- O O •D • V) W O O a..e r 4- W O O V CT O LL- r r� O co _ L 1 4-.1 Lr) 00.Ui N co N r- 7 C m 01) O CT - Y E 4-) U to L LL- A to CU L CU r to Z b +j cn— C> r-O r- LC) r\ co t0 CT O Cl) 3 .o O to H .-� M r` -4 CT O -4 N r- co mc O E I-- Le) C9 • • e • • • • 4-3 L N 4- LL r7 N .-� N N N N M V t O • L + r 3 to Lto N +-1 O d >)4-3 Z F- O O O O O O O O Ln r f\ - O Cl W O O O O O O O O •r i C U H U W d LP) t0 N Ln O N r` p M O U LiL a �--� }- M r-a t0 N CT t0 r- d L 2' W U d •-1 d O N d %.0 M CU O '> C 4-W 1- Z b- LO .-+ N M d CT co r` fs LL- y N CIO w to Ln Ln O .-+ p =D to Ln to tg: 3 1) L a 4-) 0 Z U CO O CT O O .-+ M co L O L -C O 4- G a' Q L iZ d) .- W N eo N A L N 1- W LL.

O1 CT CT (7% a1 O) LT CT 7 i As can be seen from Table 3.1, between 1977 and 1981 the Di strict's' pur- chases from the City of Portland have increased an average of 40% annually in order to satisfy growth within the District to supply the City of Tualatin, and to make up shortfalls from well production and Lake Oswego sales. The current price of the Bull Run water delivered to Bradley Corners is $.59/100 cubic feet and based on the requirements of Article 11 of the agreement, the District is required to purchase a minimum of 17.5% of its total water demand from the City during FY 81-82. F i In terms of total water consumption, as seen in Table 3.1 over the past seven years, water consumption within the District has increased from 1. 77 mgd to 2.56 mgd or an average of 5% per year. Also, the percent of total water supplied by Lake Oswego has remained relatively constant while the precent produced by its wells has fallen and the percent purchased by Portland has increased dramatically. However, after April 1983, when Tualatin will purchase water from Portland directly through its new Washington County supply line, the percent supplied by Lake Oswego will increase and that supplied by Portland will decrease accordingly. 3.3 DISTRIBUTION AND STORAGE SYSTEM 3.3.1 - Distribution System 3.3.1.1 - Ph sical Description - The distribution system of the Tigard Water district consists of a major grid of 12" ductile iron (D.I. ) and cast iron (C.I.) pipes looped into a continuous system. The local distribution laterals are mostly 6" and 8" C. I. with a ( few 4" mains on dead-end streets. There are also two major system feeds but both are as yet incomplete. One is a 24" pipe which links the Bull Run supply at Bradley Corners with the terminal storage facility at 125th and Bull Mountain Road. The other is a 16" D.I. pipe which links the Lake Oswego supply source at I-5 and Bonita Road to the same terminal storage reservoir. a 3.3.1.2 - Present Operational Characteristics - The distribution network is divided into five separate pressure zones. The first major zone serves the lower areas in Tigard with an overflow eleva- tion of 410 feet and the second the area west of S.W. 121st on Bull Mountain Road with an overflow elevation of 690 feet. The three remaining pressure zones serve small areas around the summit of Bull Mountain, the summit of Little Bull Mountian and the area west of the intersection of Bull Mountain and Roshak Road. At present, water from Lake Oswego or Bull Run is imported into the main low pressure zone and pumped to all of the higher zones and reservoirs. Pressures in two of the minor zones are stabilized with automatic pressure relief valves. Computer analysis indicates pressures in the overall system vary rather widely due to elevation differences within zones and demand fluctuations. Maximum pressures of 115 psi in the King City area require the use of individual pressure regula- tion valves. Minimum pressures of 25 to 30 psi occur along Bull Mountain Road on the upper slopes of Bull Mountain and around Springwood and 121st Avenue. 8 i Overall , however, pressure appears to be adequate with only minor refinement of the pressure zone boundaries and loop completion required. Fire flows in the systm are good to very good with most large facilities having the flow required by the local fire depart- ment and the Insurance Services Office (ISO) for insurance purposes. 3.3.1.3 - Future Operation - The District is planning to complete the two major system feedlines described above in the near future. Several smaller projects designed to complete distribution loops will be constructed later. Computer analysis indicates that with the completion of these projects, the system will be able to meet the projected year 2000 peak day demand of 10.6 mgd. Fire flows will remain acceptable and pressure will decline on the average only 5 psi except in the northern area of the district which will drop severely unless planned looping projects are completed. There is the possibility that the area east of the District boundary will be withdrawn from the system in the near future. This will make virtually no difference in system demand, but the S.W. 72nd Avenue main is important to fire flows in the southeast -corner of the Dis- trict and to the Baylor tanks. The fire flows in the southeast corner of the District would suffer severely with the disconnection of the S.W. 72nd Avenue main proposed by the Metzger Water District. Planned rearrangement of the storage system as described under Section 3.3.2.3 will improve the ability of the distribution system to absorb peak loads and fire flows. This is due to the higher head available from the terminal storage area. Otherwise, the distribution system will be relatively unaffected by this change. z 3.3.2 - Storage System 3.3.2.1 - Physical Description - At present, the District has 17.4 mg 4 of storage on line. There are a total of nine tanks at six separate sites. An additional 2.5 mg of storage is presently under construc- tion at S.W. 135th and Fern Streets. This will bring the total storage up to 19.9 mg. Two additional reservoirs are planned by the .District on S.W. 150th Avenue for an eventual total storage of approximately 23 mg. The tanks are generally in good condition with only minor work required. The steel tanks will , however, require painting in the near future, probably within the next three or four years. 3.3.2.2 - Present Method of Operation - Two of the tanks serve the upper pressure zone on Bull Mountain, with overflow levels of 690 feet. One 10 mg tank serves as a "terminal storage facility" with an overflow level of 470 feet. The remaining tanks serve as distri- bution storage for the lower pressure zone with overflow levels of 410 to 417 feet. At present the upper zone reservoirs are supplied via the pump station at site no. 2 just off Gaarde Road and S.W. 120th. The pump station �: 9 at S.W. 135th and Fern is kept in reserve. The upper pressure zone is then served by gravity except for a small pump station taking care of the area directly adjacent to the tank. The lower reservoirs are connected directly to the lower pressure zone and are thus supplied directly by the District's primary source of supply, be it Bull Run or Lake Oswego. All of the distribution reservoirs are equipped with appropriate valving. There is also one additional pumped system which serves the higher elevation , areas adjacent to the District shops on Canterbury Lane (Little Bull Mountain). The 10 mg "terminal storage" facility located on S.W. Bull Mountain Road has an overflow elevation of 470 feet. This reservoir is at present kept full via the pump station at site no. 2 off Gaarde Road and S.W. 121st. The reservoir is used only for emergencies at present and is manually controlled. 3.3.2.3 - Future Operational Characteristics - The District is planning to make major changes in the method of system operation in the near future. With the completion of the 24" and 16" major input lines from the 10 mg tank to the Bull Run and Lake Oswego master meters, the District will be capable of completly isolating all inflow to the 10 mg tank. Future District plans call for running all imported water into this terminal storage tank via the new lines for distribution to the various areas of the District. This will require all incoming water to be raised to the 10 mg tank's operating level , somewhere around 470 feet. The 10 mg tank will then become the distribution reservoir with the other tanks being kept full to provide emergency storage. 3.3.3 - Commentary 3.3.3.1 - Distribution System - The distribution system appears to be very adequate for carrying all present and projected loads through the year 2000 assuming planned improvements are carried forward. } While isolation of the large terminal storage feed lines would improve the capability of the system, this should not be required for the foreseeable future. Disconnection_ of the S.W. 72nd Avenue main by the Metzger Water District as discussed above will force the district to replace the section of main south of Bonita Road. If this is not done, computer modeling indicates fire flows in the southerly portion of the District will decline to approximately half their present levels. This problem could be offset if hydrants are available on the other large diameter pipes in this area. 3.3.3.2 - Amount of Storage - The District's average demand is pre- dicted to be 4.3 mgd in t e year 2000. With completion of the 2.5 mg reservoir under construction, there will be 19.9 mg of storage available. Thus the ratio of total storage to average daily demans is 4.6, well above the usual ratio of 3. With the pipe grid avail- able, this extra storage is not needed for distribution. The current 7 4 { 10 extra storage is apparently deemed necessary by the District to cover interruptions in supply and possible future needs. 3.3.3.3 - Operation of Storage System - The District's operational p ans or diverting all water through the 10 mg terminal storage reservoir will have major effects on the system. It will require all water to be pumped to the terminal reservoir's operating level , approximately 470 feet. While the system will be able to supply sufficient water at adequate pressure, operating costs will take a increase slightly due to the increased pumping required for lower pressure Lake Oswego water. If Lake Oswego water was used exclu- sively, the 2.6 mgd demand predicted for next year would result in an additional power cost of $9,300 per year assuming an efficiency of 65% and power cost of $.035 per kwh. This cost would be expected to climb to approximately $16,000 per year by the year 2000. This impact will increase the cost of water by approximately $0.0074 per 100 cubic feet at power costs of $0.055 per kwh. This additional power cost could be reduced by -allowing the Lake Oswego pumps to supply the lower pressure system directly with the 10 mg reservoir held in reserve, but equipped with automatic valves for instant availability in case of emergency. 3.3.3.4 - General - It appears the District has been faithfully following the general plan put forth by Stevens, Thompson and Runyan, Inc. in its report of 1971 entitled, Water Supply and Distribution Study. Since conditions have changed somewhat from those prevailing when the report was written, it is important that future plans be updated. While large amounts of storage at higher than system average pressure may be appropriate for the high pressure Burlingame system for example, such storage is not necessarily appropriate for a district importing water at low pressure, such as from Lake Oswego. In summary, the District's water system is in good to excellent con- dition and adequate for expected future demands. Careful re-examina- tion of planned changes in the District's operational methods, however, should yield substantial savings to the District , especially in power and capital costs for pump stations. 3.4 FINANCIAL STATUS An evalua-t-To—n--oT the financial status of the Tigard Water District was made by examining the District's budgets and budget reports for FY 82-83 and FY 81-82 and the audit reports for FY 80-81 through FY 77-78. The District's accounts are maintained on the fund accounting basis as required for budgetary reporting. The District's major funds consist of the General Fund, the Bond Sinking (Debt Service) Fund, and Bond Construc- tion Fund. The balance in the latter fund is zero since all funds 'in it were expended as of June 3, 1979. Consequently, all capital improvements f after this date have been financed out of the General Fund. Table 3.2 shows the status of the Bond Sinking Fund from FY 77-78 through FY 82-83. This fund is used to pay the principle and interest on seven separate bond issues sold between October 1962 and December 1976.

Annual payments on bond principle and interest will peak during FY 82-83 at $318,519 and will decrease to $163,912 when all bonds are retired in FY 1995-96. FY 81-82 is the first year in which a transfer of money from the General Fund has not been used to liquidate the debt. Because it is anticipated that, as the bond debt decreases over the years, assessed valuation in the District will increase, the tax rate can be decreased accordingly assuming no new bonds are sold which are to be financed out of tax revenues. When considering the sale of new bonds, it must be remembered that the current bond debt will not be retired for another 14 years. Table 3.3 shows the status of the General Fund from FY 77-78 through FY 82- 83. A number of items are worthy of note. The beginning balance has been increasing substantially since FY 80-81. In addition, water sales have increased greatly due to the fact that the District has supplied the City of Tualatin with all its water since May 1980. Prior to this date, water sales averaged approximately 70% of revenue, but since this date, the percentage has risen to 90%. During FY 80-81 and FY 81-82, the District sold approximately $361,000 and $395,000 respectively of water to Tualatin at $.68/100 cubic feet, while the cost of that water to the District was approximately $.32 per 100 cubic feet. Therefore, in FY 83-84, when Tualatin obtains its water directly from Portland, the District's income will drop by about $400,000 and the corresponding profit of approximately $188,00 will no longer be available for District use. In terms of expenditures, personnel services have historically made up about 25% of the District's total expenses. However, for FY 82-83, they will be only 18.5% due to the unusually large capital outlay and the fact that the staff will be reduced from 13 to 11 employees. Water purchases have increased dramatically due to the growth in consumption especially with the addition of Tualatin in May 1980 and due to the fact that a greater percentage of water purchases have been Bull Run water which is almost twice as expensive as Lake Oswego water. However, in FY 83-84, the amount of water purchases will fall because Tualatin will no longer be a customer. Finally, the healthy amounts for capital outlay reflect the District's vigorous line extension, line replacement and meter installation programs. In addition, the capital outlay budget amount for FY 82-83 includes $640,000 for a 2.5 mg reservoir to be located at S.W. 135th and Fern. A final examination was made to compare the total cost of water to the average Tigard residential customer with that of other residential cus- tomers in surrounding cities and water districts. For the Tigard Water District customer, the total cost of water consists of a combination of the commodity rate of $.75 per 100 cubic feet plus the tax rate of $.45 per $1,000 of assessed value. There are two ways to combine the rates. The first consists of taking the total amount of tax revenue raised for the Water District and dividing it by the total water consumption for the same year, which equates to $.20 per 100 cubic feet for FY 80-81, and adding this to the commodity rate of $.75 per 100 cubic feet for a total of $.95 per 100 cubic feet. Thus the customer pays $8.00 bi-monthly plus $.95 for each 100 cubic feet over the 800 cubic foot minimum amount. _ This method is shown as Modified Water Rate Structure I in Table 3.4. 14 a, iw LA) e F d e6 tO tI) to Ll) N Ln .--r Ln d 4 E ix Ln to Cl) 1 M N 1- CO Ln n Of • • • e • e • • • t-e N 41 1 = &- C N w O O 1 !- W CU C) • Q QC 1 N d � L O U (1) d N 1 E W O t +b -0 O O O 1 O O O to O d O 4- +3 rt b O O -4 O O Ln t0 O Cl) N •-" [n -0 O 9= ¢ N .-i N 1 cv I� N O t0 ll) C O i CA rt x W N m CO m J A m aj ¢ N C O O QJ O J L W N•r- +c 'o d S•- i-) eG 'o lC) '--e t= -~ C3-inc E ¢ Ln to Cl) d M N rn Ln Ln rn ro I-Wc o L� to ¢ 3 F- o = A F- W Or r d H 4 1--- L .1.3 O O O O O O O to O d •> 1- LL- N 4-3 e6 O O Ln O O O 1\ O U O G O N -4 ri Z C•"i N o e+i t8 a7 C-) C:) M: 0) '4 re .--4 .--e .--e N d X v~i w m m 4 rt 1. i-� O 3 O o2J L ~ E of 4-A • N O ¢ O W J C C r L d Q .¢-� 4) db4 O 4- d M Z W to W C TS 1 d OW 1- •r- W C<' O Q d E t0/1 G) O to 1 N O Ln 0) d N -1 ¢ = 0) N N C C O C Ln d to C Ln •O m C.^.

WATER COSTS ON BASIS OF COMMODITY RATE a TAX RATE 16 1 The second way consists of assuming that at the tax rate of $.45 per $1000, the owner of an average residential dwelling valued at $60,000 pays $27 per year or $4.50 bi-monthly in taxes to the Water District. This $4.50 is then added to the base water rate of $8.00 bi-monthly that the homeowner must pay for the first 800 cubic feet of water regardless of whether or not he uses it. All consumption over 800 cubic feet is paid at the rate of $.75 per 100 cubic feet. This method is shown as Modified Water Rate Structure II in Table 3.4. Note that the two structures are two separate ways of looking at the total cost of water. In other words, under Structure I, the Tigard Water District homeowner may be viewed as paying $8.00 bi-monthly for the first 800 cubic feet of water whether or not he uses it, plus $.95 for each additional 100 cubic feet. Under Structure II the homeowner may be viewed as paying $12.50 bi-monthly plus $.75 for each 100 cubic feet above 800 cubic feet consumed. Because the average residential customer consumes between 1,400 and 2,800 cubic feet per month, which is a relatively small amount when compared with large commercial or industrial users, Structure II represents more accurately the total cost of water to the residential user. The total costs of water shown under the Modified Water Rate Structure II column of Table 3.4 are plotted in Figure 3.1. This shows that residential customers in Tigard rank third out of nine in terms of paying the most for water service in their regional area. It should be noted that data for Metzger's water taxes was not available. L i i 17 CHAPTER IV FUTURE SITUATION 4.1 LAND USE AND DEMOGRAPHIC DATA ® he Tigard Water istrict service area is predominantly a low to medium ® density suburban community of Portland. However, extensive strip com- mercial development has occurred along Pacific Highway 99W, Highway 217, and Hall Boulevard. Industrial development has occurred west of I-5 along the Burlington Northern and Southern Pacific railroad tracks and along S.W. 72nd Avenue, south of Highway 217. Although outside of its boundaries, Washington Square (a regional shopping center), and commercial/ professional office development in the Tigard triangle bounded by Pacific Highway, Highway 217, and I-5, exert a dominant economic influence in the Tigard Water District. In terms of existing land uses, the 5,800 acre area of the City of Tigard is presently zoned as follows: residential - 74%; multi-family - 4%; commercial - 7%; and industrial - 15%. King City is. approximately 90% residential and 10% commercial. The unincorporated area of Washington County within the Water District boundaries is essentially all residential . Therefore, approximately 75% to 80% of the Tigard Water District land area is presently zoned for residential use. In terms of future land use, it appears that over the next 20 years, the Tigard Water District's service area will continue to be a fast growing, residential , suburban community of Portland. The mix of land uses within the unincorporated Washington County area and within King City will remain the same, while within the City of Tigard, the percent of residential land will decrease to 65% and the percent of multi-family, commercial and industrial land will increase to 9%, 11% and 15% respectively. Projections indicate that population within the Tigard Water District service area will increase substantially over the next 20 years as shown in Table 4.1. On the basis of Table 2-1, of the Appendix for the Recom- mended Transportation Plan for the Metropolitan Area, March 1982, by the Metropolitan Service 'District (METRO), it i estimates that the Tigard Water District population will increase from 21,000 in 1980 to 37,000 in year 2000. This represents an overall increase of 76% or an annual increase of 2.9%. However, based on its comprehensive planning efforts, the City of Tigard projects a 106% increase in its population over the next 18 years or an annual growth rate of 4.1%. This indicates that the percent of the Dis- trict's population which lives within the City of Tigard will increase over the years. �` 18 TABLE 4.1 ANALYSIS OF TIGARD WATER DISTRICT POPULATION PROJECTIONS YEAR YEAR YEAR YEAR YEAR % GROWTH 1980 1985 1990 1995 2000 20 YEARS City of Tigard 16,000 24,000 33,000 106% Tigard Water District 21,500 25,000 29,000 31,000 37,000 76% 4.2 WATER CONSUMPTION PROJECTIONS Future water consumption in terms of average daily demand was projected by multiplying the population estimates in Table 4.1 by the average daily per capita water consumption of 115 gallons as reported on Page 18 of the June 1980, Tigard Water District Water Supply Study. Historically, per capita demands have increased with time. However, in recent years, they have appeared to stabilize and the trend to water conservation will tend to decrease them. Therefore, to account for the fact that commercial and industrial uses are projected to increase slightly more than residential uses over the next 18 years, no increase in the per capita demand is anticipated. The peak day demands were then determined by multiplying the average daily demands by a peaking factor of 2.5. Table 4.2 shows the results. TABLE 4.2 Projected Averaqe Daily and Peak Day Water Demand 1982 1985 1990 1995 2000 Average Daily Demand (mgd) 2.6 2.9 3.3 3.8 4.3 Peak Day Demand (mgd) 6.5 7.2 8.3 9.5 10.6 4.3 WATER SUPPLY ALTERNATIVES 4.3.1 - Introduction In order to meet its projected demands, the following water source options may be available to the Tigard Water District: 1. Clackamas River water from Lake Oswego. d 2. Bull Run water from the City of Portland via the Burlingame pumped system or the Washington County gravity supply system. 3. Trask-Tualatin water from the Joint Utilities Commission. 4. Willamette River water through development of a surface supply or Ranney Collector. 19 Each option and sub-option is evaluated below in terms of quantity of water available, timing of water availability, costs, and institutional and financial constraints. As explained above, development of groundwater within the boundaries of the Water District is not a viable option because of the critical groundwater t area designation and limitations on pumping. 4.3.2 - Clackamas River Water As discussed earlier, the City of Lake Oswego has just recently increased the capacity of its water treatment plant to 16 mgd and the capacity of its Waluga Reservoir to 4 mg. Because its present peak demand is 11 mgd, the City can produce up to 5 mgd of surplus water which it is willing to sell to the Water District on an "as available" basis under the terms of the existing agreement. Consequently, the District has added a third 1,650 gpm pump to its booster station near I-5 and Bonita Road in order to increase peak pumping capacity to approximately 6 mgd. The cost of this water to the District is currently $.31/100 cubic feet, but the price is projected to increase to $.40 within a year after the City staff and Council complete the rate review process. Further rate increases will parallel the cost escalation of electricity, chemicals and f labor necessary to treat and pump the water. The question of availability of this surplus water depends directly on the rate of Lake Oswego's growth. The August 1977 Revised Water S stem Stud for the City of Lake Oswego projects that the City--s peak demandwill equa the 16 mgd capacity of the water treatment plant in 1991, necessitating another expansion of the plant to 21 mgd and an increase in transmission line capacity to and from the plant. What this means for the Tigard Water District is that between now and 1990, the availability of surplus water will diminish in direct proportion to Lake Oswego's increase in water demand as it did in the late 1970's before the plant was expanded to its present capacity. The expansion to 21 mgd is projected by the same study to meet demand until 1998, so the diminishing supply problem would repeat { itself once again before the year 2000. Deficits in demand would have to be made up from another source such as Portland's Burlingame system. And as illustrated in Figure 4.1, this deficit in demand will increase over time as Tigard Water District demand grows. In terms of the Tigard Water District's obtaining a firm supply of water from the Clackamas River, Lake Oswego may, at some future date, be willing to consider joint development of its supply. However, because existing water rights for water supply are over-allocated relative to the available supply during low flow periods, more upstream storage capacity would have to be constructed to meet minimum flow requirements. These circumstances present institutional and financial constraints which may make the Clacka- mas River infeasible as a long-term source for the Tigard Water District. 4.3.3 - Bull Run River Water t Five years remain in the year agreement between the Tigard Water District and the City of Portland for provision of a firm supply of surplus water. 20 s - t ci E Z 0 - W Y W d W a W 0 N W U w F W O W Cc Z ~ Ck Q J F- (n f- W W O > 0 p W a.

The District so notified Portland that it wanted a 10-year renewal. However, Portland countered with an offer of a 25-year contract which the other East Washington County water purveyors on the Bull Run system have already signed. After much deliberation, Tigard Water District signed the 25-year contract on May 14, 1982. These 25-year contracts were first offered by Portland in 1979 at the same time the City overhauled its rate structure. The City wanted 25-year commitments from all of the outside water purveyors so it could plan and construct long-term improvements to its supply system including a 100 mgd back-up water source from the groundwater aquifers along the Columbia River. In order to make the contracts attractive, the City changed its rate-making philisophy to the cost of service concept which resulted in dropping of the systems development charge for all new outside City customers and lowering of its rates to all outside' water purveyors. In that water rates to outside purveyurs are now based on the cost of service concept, water prices increase in direct proportion to the amount of pumping required and distance over which that water is transported to deliver it to the customer. In view of this fact, the Wolf Creek and Metzger Water Districts and the City of Tualatin elected to buy Bull Run water at the new 50 mg Powell Butte Reservoir and share the costs of constructing a new pipeline to convey that water by gravity to Washington County rather than to continue purchasing pumped water from the Arlington Heights and Burlingame systems. The actual cost of that new 60" pipeline including the cost of oversizing a section of a Portland line between the Powell Butte Reservoir and S.E. 67th and Holgate is $15.9 million as opposed to the original estimate of $19 million. From the Washington County line, the Wolf Creek Water District will construct a main ranging in size from 54" down to 30" and costing $7.5 million to transport that water throughout the District. The Metzger Water District and the City of Tualatin are constructing a 48" line from the termination of the 60" line to the Metzger Reservoir complex at a cost of $2.5 million and a 36" line from there to Tualatin's reservoir at an estimated cost of $3.13 million. Each of the jurisdictions states that the cost of Bull Run water purchased at Powell Butte for $.32/100 cubic feet plus the 20-year ammortized cost of constructing its share of the necessary gravity transmission mains will be equal or less than the $.71/100 cubic feet cost of water delivered to Bradley Corners. Presently, the cost of water to Bradley Corners is $.59 but Portland will increase it to $.63 on July 1, 1982, and to $.71 when the 60" gravity system goes into operation during April 1983. In terms of future water prices, the cost of the gravity system is essentially fixed by the ammortized construction cost while the price of water purchased at the Powell Butte Reservoir will increase at a much lower rate than that for water from the Burlingame or Arlington Heights systems which will inflate with the cost of electricity for pumping. Therefore, the gravity system will provide less expensive water than Portland's pumped systems. 22 Y LAJ F- terCJI w Ln O O v� c Y Q 3 Ln Cn Lc; • t J U O Ln .•-4 W cm C Cl- CL O 4J L d S b N N 4-3 rcl, c ro Y J LC) r O 0 3 j ?

However, with respect to the former systems, 88.5% of the capacity of the 60" gravity line is owned by the Wolf Creek Water Distruct which in ,l, turn assigned 15% to the Metzger Water District and 18% to the City of Tualatin, leaving Wolf Creek with 55.5%. The remainder of the line's capacity is apportioned at 1.5% to Raleigh Hills and 10% to Portland. w Therefore, Tigard Water District must negotiate directly with one of the three East Washington County purveyors for water from the gravity system. Table 4.3 compares the projected demands of each of the three East Washing- ton County purveyors with their purchased share of the gravity line's 61 mgd capacity. The table shows that by 1990 the peak day demand of the three jurisdictions will equal or slightly exceed their alloted capacity of 54 mgd. This means that if Tigard Water District is able to negotiate an agreement to buy surplus water from one of the three jurisdictions, water will only be available in decreasing amounts until 1990. The capacity of the 60" line could be increased to approximately 85 mgd by the addition of a pump station or the construction of Conduit 5 which will be able to provide increased pressure directly from the Bull Run dam. However, if and when the 60" line capacity is increased, it will just be able to accommodate the year 2000 demand projected for Wolf Creek, Metzger and r Tualatin. It should be noted that all three jurisdictions have informally indicated a willingness to sell water to the Tigard Water District, but it would be only on an "as available" basis and significant tie-ins, especially from Wolf Creek, would be required. Because Wolf Creek, Metzger, Raleigh Hills and portions of Portland will be transferred from the Burlingame system to the gravity system in April 1983, Burlingame peak demand will decrease from approximately 30 mgd down to 10 mgd. Since the Burlingame system has a capacity of 31 mgd, there will be ample capacity to serve all of Tigard Water District's needs beyond year 2000. Therefore, a firm supply of surplus Bull Run water is available to serve the District's future needs, but it will only be available at a premium price. 4.3.4 - Trask-Tualatin System !Fie ras - ua a zn sys em, originally developed by the City of Hillsboro, is owned, as of April 17, 1979, by Hillsboro (50%), Beaverton (30%), and Forest Grove (20%) and is operated by a Joint Utilities Commission con- sisting of representatives from the three cities. The system consists of a dam and reservoir on the eastern portion of the Trask River watershed which is located on the west side of the Coast Mountain Range. Water from the reservoir is diverted through the Coast Range to the Tualatin River by means of a tunnel. A 20 mgd water treatment plant above Dilly treats water from the Tualatin River and pumps it to the 21 mgd Spring Hill Reservoir and from there into Hillsboro for distribution. In addition to the Trask Reservoir, the system relies of a share of water from the ( Scroggins Dam in order to produce a current safe yield of 23.3 mgd from the Tualatin River for municipal uses. 24 Presently, the peak summer demand of the three municipalities approaches the 20 mgd capacity of the water treatment plant. Therefore, the Joint Utilities Commission foresees expanding the plant and raising the height of the Trask Dam within the next five years. The water treatment plant is designed to be expanded to 60 mgd in two additional phases in order to meet the year 2000 projected neds of the three cities. In addition, the Joint Utilities Commission states that the storage capacity of the Trask Reservoir can be increased sufficiently so that when combined with its rights to Scroggins reservoir water the system will yield 60 mgd of t municipal water. IIn terms of availability of Trask - Tualatin water to the Tigard Water District, Beaverton presently sells water to the District on an emergency basis through a small intertie at $.565/100 cubic feet plus a 10% markup charge. However, the Joint Utilities Commission will not have a firm supply of surplus water until the Trask Reservoir, water treatment plant, reservoir and transmission mains are expanded to 40 mgd. It appears that at that time the Commission may be willing to allow Tigard to become a Part owner of the system. As evidenced by Beaverton's 1979 cost of almost $7 million for purchasing its 30% share of the dam, treatment plant, reservoir and transmission lines, the cost of Tigard Water District's buying-in will undoubtedly be considerable. However, at this time, estimates of that cost would be meaningless. None the less, the Trask- Tualatin system will be an option for the Tigard Water District to investigate for use sometime after 1985. 4.3.5 - Willamette River - Of all the source alternatives proposed for the Tigard Water District, the Willamette River is the only one which is not developed to date in the Portland area. Because developing a new water source is a costly undertaking, the question should be asked as to who might be interested in developing the source with the Water District during the next five to ten years as available surplus water supplies from other purveyors become increasingly scarce. As discussed above, Beaverton and Hillsboro can meet their year 2000 projected needs from the Trask-Tualatin system. Lake Oswego has sufficient :nater rights to meet its future needs until year 2000 assuming the minimum flow problems of the Clackamas River can be resolved. The cities of Sherwood and Wilsonville appear to have adequate groundwater resources to meet their year 2000 projected needs as well. Finally, the City of Tualatin and the Wolf Creek and Metzger Water Districts have sufficient capacity from the 60" gravity main to meet their projected 1990 needs and the option to increase that capacity through construction of a pump station or conduit 5 to meet their year 2000 needs. Therefore, it would appear that the Tigard Water District would be forced to develop the Willamette River by itself if it chooses to do so in the near future. Two alternatives for developing the Willamette River are examined in detail below: 1. Surface water at Wilsonville. 2. Infiltrated water at Newberg. 25 Both alternatives originate from previous studies. The former was first proposed in the January 1969, Tualatin Basin Water and Sewer Master Plan and then developed in more detail over t e _n_e_x__t__U years in five other engineering reports as the East Washington County water purveyors attempted to decide whether to develop this source or to sign 25-year supply contracts with the City of Portland. For purposes of this study, it was assumed that a water intake structure and water treatment plant with high head pumps would be constructed at Wilsonville. A 10.6 mile, 36" diameter transmission line would transport the water to the 10 mg terminal storage reservoir. Because of the great elevation difference between the river and the reservoir, a booster pumping station located along the transmission main would be required. All facilities would be sized and constructed to meet the District's projected year 2000 peak day demand of 10.6 mgd. In terms of treatment requirements, an analysis of the Willamette River water quality at Wilsonville was conducted by Stevens, Thompson and Runyan, Inc. from October 1975 to October 1976. This analysis indicated that conventional treatment processes of fioculation, sedimentation and filtra- tion would produce water meeting June 1977 Oregon standards. However, U.S. Environmental Protection Agency regulations effective since the end of 1979 require removal of synthetic organic compounds. This can best be accomplished by carbon adsorption in addition to conventional treatment. Therefore, the treatment process assumed for this alternative consists of conventional treatment with granular activated carbon incorporated in the filter medium. The alternative for developing infiltrated water at Newberg was proposed in the June 1980, Tigard Water District Water Supply Study. This report invisions using Ranney Collectors which consist of reinforced concrete i caissons sunk near the riverbank from which laterals are projected horizontally into the alluvial sands and gravels to collect water under the river. The caisson serves as a clearwell from which the water is pumped. In its October 24, 1980, study entitled. Report on Hydrogeological Survey Y for the Tigard Water District, the Ranney Method Western Corporation, which Wilds the.patent on the anney Collector stated that the Ash Island area near Newberg is one of three areas along the Willamette River near Tigard which has sufficient alluvial sands and gravels for development of a major water supply using the Ranney method. Furthermore, as a result of two pumping tests conducted on test wells drilled along the Willamette River bank opposite Ash Island, the Ranney Corporation concluded that two Ranney Collectors located and constructed as recommended in the report would produce a minimum of 12 mgd of water. As to quality of water produced by the Ranney Collectors, the report states that, "...with the exception of iron and manganese, the water samples collected from the test wells are below maximum contaminant levels as set forth in the EPA Secondary Drinking Water Regulations. ...the inorganic chemical quality of the water- pumped during the tests, including iron and manganese, is higher than that of the Willamette River. This is to be expected since groundwater was discharging into the river at the time of the tests and therefore the water produced during the tests was primarily 26 s i f TABLE 4.4 ANALYSIS OF TIGARD WATER DISTRICT COST COMPARISON OF WILLAMETTE RIVER ALTERNATIVES SURFACE WATER AT WILSONVILLE RANNEY COLLECTOR AT NEWBERG CAPITAL CAPITAL ITEM COST $1000 ITEM COST $1000 Intake and Pump Station 450 Ranney Collectors (2) 1,400 Booster Pump Station 280 Booster Pump Station 280 Treatment Plant: 6,450 Treatment Plant: 3,200 - 5,200 Conventional with filtration with granular activated granular activated carbon carbon Transmission - 56,000 ft. 5,040 Transmission - 79,200 ft. 7,130 of 36" diameter pipe of 36" diamater pipe River Crossings (2) 600 Land - 10 acres 10 Land - 10 acres 10 TOTAL CAPITAL COST $12,230 TOTAL CAPITAL COST $12,610 - 14,610 NOTE: Costs are in May 1982 dollars and include 30% for engineering and contingency.

However, once the Ranney Collectors have been constructed and pumping has commenced, the highly t mineralized groundwater will be replaced with infiltrated river water and �! the inorganic chemical quality will approach that of the river. Thus, the iron and manganese contents, which slightly exceeded the EPA maximum contaminant levels during the tests, can be expected to decrease to trace amounts. "Based on the results of the pumping tests and our experience with existing Ranney Collectors in similar hydrogeological situations, the inorganic chemical quality of the water produced from the Ranney Collectors will approach that of the Willamette River, with individual mineral constituents ® remaining about 10 to 20% higher than those of the river. Furthermore, j being naturally filtered, the water produced will be clear and free of sand, silt, turbidity and pathogenic basteria." Based on the foregoing statements, it was decided that conventional treat- ment for turbidity removal will not be necessary. However, chlorination and filtration should be provided for iron and manganese removal in case 1 these constituents fail to decrease below recommended limits. In addition, because the water quality will approach that of the Willamette River, graduated activated carbon should be provided in the filter media for synthetic organic compound removal. Therefore, for purposes of this study, it was assumed that two Ranney Collectors with necessary pumps would be constructed at the test hole site. Water would be pumped under the Willamette River to a water treat- ment plant with high head pumps near Newberg. A 15-mile 36" diameter transmission line would transport the water along Highway 99W to the 10 mg terminal storage reservoir. As with the first alternative, an inter- mediary booster pumping station was also assumed. The capital and annual costs for both alternatives were determined in May 1982 dollars (ENR = 3800) and are summarized in Table 4.4. Because of the uncertainty in the type and degree of treatment required for the Ranney Collector water, a range in capital costs was projected. The ammortized capital costs were based on 20-year bonds at a 10% interest rate. The average cost per 100 cubic feet of water was computed for both alternatives in terms of 1982 dollars based on the projected 1985 and 2000 demands of 2.9 and 4.3 mgd respectively. The results show that although approximately 19% more expensive in terms of operation and maintenance costs, the surface water will most likely be less expensive than the Ranney collector water in terms of the total annual cost and cost per 100 cubic feet. 4.3.6 - Future Cost and Availability of Water Sources After describing each of the water source options available to the Tigard Water District, an attempt was made to project their future cost and availability. The results are shown in Table 4.5 and Figure 4.2. The price of each source in $/100 cubic feet was broken down into two components: 1. The amount attributable to ammortized capital cost to be incurred by the District to develop the source, which ::as assumed to be fixed over the next 20 _years, and 28 2. The amount attributable to operation and maintenance costs which was assumed to inflate each year at an average rate of 6%. Since the Water District will be buying surplus water from Lake Oswego through an existing distribution system, 100% of the price of Clackamas River water was assumed to inflate at 6% per year. However, the estimated price could rise more rapidly if the District is asked to help pay capital costs in the future to increase the capacity of Lake Oswego's transmission mains from its water treatment plant. The same assumptions were made for Trask-Tualatin water supplied by the City of Beaverton. According to the Portland Water Bureau, the wholesale price of Bull Run water at the point of delivery will increase at the rate of inflation plus 3% until 1988 to recover Portland's costs for capital improvements, and then after that date it will increase at the rate of inflation. Since the price of Bull Run water delivered via the Burlingame system to Bradley Corners will be $.71 as of April 1983, it was assumed that this price would increase by 9% annually until 1988 and then by 6% until the year 2000. If the Tigard Water District is able to buy surplus Bull Run water from the 60" gravity supply line, it was assumed that this water would be available initially at a price equal to or less than the April 1983 price of the Burlingame water. This price would consist of the $.32 per 100 cubic feet wholesale price of water delivered to Powell Butte, which would inflate at 9% until 1988 and then at 6%, plus a fixed ammortized capital cost of $.39 per 100 cubic feet, which would represent Tigard's cost to use the 60" and 48" gravity lines owned by Wolf Creek, Metzger, Tualatin and Portland. From Table 4.4 the fixed ammortized portion of the total unit cost of surface water from the Willamette at Wilsonville and hater from the Ranney Collector were determined to be 73% and 78% respectively. The remaining operation and maintenance portions of the total costs were assumed to inflate by 6% per year. The 1982 costs listed in Table 4.4 were inflated to 1983 assuming construction in that year. However, it should be noted that as construction is delayed into the future, the ammortized construc- tion cost portion will inflate which in turn will increase the dollar E cost per 100 cubic feet. As shown in Table 4.5 and Figure 4.2, between now and 1990, the least expensive water in order of increasing cost will be from Lake Oswego, the Bull Run gravity supply system and the Trask-Tualatin system. However, because it appears that only surplus water will be available from these F sources on an "as available" basis, they will be the least reliable. In addition, as shown conceptually in Figure 3.1, as their own demand grows, these suppliers will have decreasing amounts of surplus water available. In fact, after 1990, the availability of all of these supplies on a surplus basis is highly questionable and should not be relied upon by the Tigard Water District. Therefore, because the, low cost options will most likely be unavailable after 1990, this leaves the most expensive options of Burlingame water and the Willamette River waters as Tigard's only alternatives for a firm 29 TABLE 4,5 ANALYSIS OF TIGARD WATER DISTRICT PROJECTIONS OF COST AND AVAILABILITY OF WATER SOURCES PROJECTED COST IN INFLATED DOLLARS ($ PER 100 CUBIC FEET) SOURCE 1983 1985 1990 1995 2000 1.

As seen from the Figure 4.2, the Willamette River options appear to be less costly in the long run than Burlingame water. However, this assumes construction of one of the Willamette River alternatives in 1983 which is most unlikely. A more likely senario is construction between 1985 and 1990. However, by that time, construction costs will most likely inflate to the point where Burlingame water will be the less costly. In addition, the September 1980, Tigard Water District Bond Feasibility Study prepared by the First NationaT-8-a—nkofregon raises considerable question about the District's ability to handle the debt service impacts of a $12 to $16 million bond issue to finance one of the Willamette River alternatives. Therefore for the short term, the Tigard Water District can continue to buy water at the lowest price from anyone who is willing to sell surplus water. But in the long term, the District must turn more and more to alternative supplies of water. At this time, the Burlingame water appears to be the most reliable and least cost option. However, this option will -- require that the District's retail rates be raised substantially in the future. In addition, if a commitment is not made in the near future, the City of Portland may not be able to meet Tigard's long-term needs since they need to know Tigard's intent in order that they can adequately plan for their long-term needs and capital investment project. i 6 �g 32 ® TURRH RUH [ HU PHIME MIRIct P.O. BOX 27 • TU I ALATIN OREGON 97062 • PHONE 682-2601 • RUSSELL WASHBURN, CHIEF s v � May 24, 1982 TO: Tigard City Council FROM: Tualatin Rural Fire Protection District RE: Fire Protection Ramifications of Assumption of Water District Liabilities by the City of Tigard The Tualatin Rural Fire Protection District has traditionally provided cost-conscious emergency services to its' citizens, and will continue to do so. There is a great deal more involved in the provision of cost-efficient emergency fire protection, however, than can be impacted by the budgetary processes of the fire district alone. Reciprocal cooperation between government agencies is an absolutely essential in- gredient in the formula. With particular regard to the availability of emergency and standby water, the following three factors are crucial : 1 . The total amount of water available within the system. 2. The capability of the system to move water throughout the community. 3. The availability of the water supply to the fire department, wherever and whenever it is needed. Excellent historical cooperation between the Tualatin Fire District and the Tigard Water District, for example, has resulted in a Class 3 fire insurance rating for the residents of the City of Tigard. Depending on the exact location and value of a given home, this very good fire insurance classification (Class 1 is the best) could result in an approx- imate fire insurance premium savings of 30% to 45% under what the premium would be if the classification was 2 or 3 points higher. Premium savings for businesses could be even more significant. From the standpoint of total costs for services, the following points merit consideration: 1 . Standby water charges for sprinkler systems. A. These charges impact total fire protection costs to the business owner in several ways. The owner must first determine, from a purely business standpoint, how the amortization of the sprinkler system itself will affect future plans. The owner must then factor in the cost of 2 - standby water and the difference in insurance premiums between a sprinklered and unsprinklered building. If the standby charges are too high to jusitfy, the owner may choose to delete the sprinkler system from the building. This decision will not only raise the fire insurance premiums to the owner, but it very probably will result in a larger fire (should one start) than might otherwise be expected = thereby necessarily increasing the number of fire personnel and apparatus required to extinguish the fire. If this trend is continued over time, it will ultimately necessitate a significantly larger (and proportionately more expensive) firefighting force than might otherwise be required. 2. Maintenance ,of sufficient water system capacity to assure required fire flow. A. If required fire flow (in gallons-per-minute) is not available, then the scenario in point #1 is moot, since the business owner will not even have the option of considering sprinkler protection. What would be even worse is if an inadequate fire flow existed in the water mains for fire department use in extinguishing what could potentially be a larger fire than if the building was protected by sprinklers (a real potential example of a "Catch 22") . 3. Hydrant installation fees. A. Presently, the fire district pays no hydrant installation fees. Part of this trade-off includes that the fire district parti- cipates in hydrant testing and maintenance. The need for personnel to be familiar with hydrant location and capacity results in every hydrant in the district being visited by fire personnel on a scheduled basis. Since that need is required, and on-going, it makes sense to involve fire district personnel in the hydrant maintenance program. In turn, this activity results in saved manhours for the water district. Any change in this arrangement should be weighed carefully, as it could impact the total cost of both fire protection and water services. The Tualatin Rural Fire Protection District has an obvious and significant interest in water administration and delivery within its ' boundaries, as those considerations impact both the quality and cost of the services we provide. It is our position that the Tigard Water District has been an exemplary example of how previously mentioned inter-governmental cooperation can work to provide the highest possible level of coordinated services at the lowest possible cost to the taxpayer. . With this presentation, we respectfully request that the Tigard City Council very carefully weigh : the cost/service implications of assuming water district liabilities, from the standpoint of what is the most cost-efficient method of providing equal levels of service. 3 - Thank you very much for this opportunity to provide input, and if any questions remain, please do not hesitate to contact us.

Cedar Point Builders Jim Christopherson May 20, 1982 MEMORANDUM TO: City Council FROM: Jeremy Coursolle, Associate Planner SUBJECT: Conditional Use Standards During the last few mor_ths, there has been an increasing difficulty in ad- ministering the existing zoning ordinance due to the inconsistencies and lack of flexibility described in the permitted and conditional use sections of each zoning district. To alleviate these problems, staff suggested that permitted uses be combined and described as use types, i.e. general retail, rather than pet store, book store or flower shop. Additionally, staff defined conditional uses as only those use types that have major impacts within a zoning district, i.e. a school within residential zone. Another problem related to conditional uses is that there are no standards or criteria described in the zoning ordinance in which to evaluate the merits of a conditional use proposal. Staff has incorporated these criteria and standards into the redrafting of the conditional use section of the zoning ordinance. The following recommended additions to the zoning ordinance are attached to this memorandum: Section 18.72 - Conditional Use process; Section 18.20-18.52, which list the permitted and conditional use types within each zone; the use type classifications, which define each use type and a matrix of use types (the matrix is not proposed to be incorporated into the zoning ordinance. On May 18, 1982, the Planning Commission reviewed staff's final proposal and recom- mended to the City Council that they approve staff's proposals. Since the Planning Commission recommendation, staff further reviewed those use types that would be permitted in multiple family zones. It is staff's recommen- dation that single family detached dwellings should also be included in multiple family districts on lot sizes now permitted within each zoning district which are: A-12 - 3,630 square feet, A-20 - 2,178 square feet and A-40 - 1,089 square feet. Permitting this use type would allow many property owners to utilize small, otherwise unusable lots and allow for more flexibility in dwelling unit types within multiple family zones. RECOMMENDED ACTION: At this time, staff is requesting that the City Council review the proposed zoning ordinance text changes recommended for approval by staff and the Planning Commission. Therefore, no action is neer' On June 14, 1982 staff will present an ordinance to City Council for adoptir _, :�f *nese proposed text; changes.

Paterson, et al Our File: 12 , 836-41 Dear Bob: At the May 17, 1982 City Council meeting, I expressed my disappointment at the September 22 trial date we had been given for this case. I did not go into a lot of detail on that occasion, but I called Judge Bonebrake personally and asked him to give us a date, and I had the impression that the September 22 date was what he had done for us. I would be very hesitant to complain about that, because I know that he would try to do his best for us, and so on that night I was assuming that he had done his best and that was all he could do. I have now received in the mail a notice changing the trial date to June 11. Obviously what happened was that in the ordinary course of things, the case got set for September 22 , and then when he got around to taking care of our personal request made directly to him, he was indeed able to do much better. It is now scheduled for June 11, and I have alerted the witnesses who will testify for us to that new date. I think Loreen is going to write a note to the City Council to inform them of the change too. Very truly yos, Joe D. Bailey / JDB/ls cc: Edward J. Sullivan, Esq. - v O V.
