Call to Order The meeting of the Intergovernmental Water Board was called to order at 5:30 p.m. on February 14, 1996. 2. Roll Call and Introductions Roll was taken and all Board Members were present. 3. Executive Session �. Since Mr. Monahan was not present as this time, this agenda item was delayed until his arrival. 4. Visitor Comments There were no visitor comments. 5. Approval of Minutes A motion was made by Commissioner Manning and was seconded by Commissioner Hunt to approve the meeting minutes of the January 10, 1996 meeting. A voice vote was taken and was passed unanimously. 6. Election of Officers Commissioner Hunt made a motion to nominate Bill Scheiderich for another term as Board Chairperson since Mr. Scheiderich had done such a good job as Board Chair and is very well informed on the issues before the Board. This motion was seconded by Commissioner Manning and was voted upon unanimously. Commissioner Manning made a motion to nominate Beverly Froude for the position of Vice Chair which was seconded by John Budihas and passed unanimously. 1- Prior to going into Executive Session, Mr. Monahan had one item for discussion. Mr. Monahan stated that the Tigard City Council had passed a resolution the night prior in regards to the recent storm, which will enable the City the ability to seek State, Federal and County assistance to deal with private property damage as well as damage to City facilities to include the water service area. At this time, we are not aware of any damage to the transmission lines or water related facilities, but we want to be in a position to apply for this assistance if necessary. Mr. Monahan stated he had spoke with the City Manager from King City and Durham in regards to passing this resolution for disaster relief and would like this to also include the Tigard Water District. Mr. Monahan stated that it was his belief that the City has the authority to make application for disaster relief for any damage to facilities on behalf of these other jurisdictions, although it would be best if each jurisdiction passes the resolution themselves. Mr. Monahan requested that the members take the resolution distributed back to their respective jurisdictions for consideration. Chair Schederich questioned whether the flood waters in Tigard were considered contaminated? Mr. Wegner stated at this time, we have had no indication of that. Mr. Wegner continued to say that we had experienced considerable flood damage at Cook Park, an electrical problem at the High Tor Reservoir site and a potential damage to one storm and sanitary line. The Board discussed whether clarification was needed on which portions of the City are served by Bull Run water and which are not, since there are conflicting reports in the media? Mr. Wegner stated that Tigard had released it own news • release and the City had decided early in this process to go with water conservation program due to the unsurety of what Lake Oswego would be able to do during the storm. With the potential of purchasing water from Portland we needed to be in step with their program. We did on 2-13-96 begin buying water from TVWD (Bull Run) and with Lake Oswego's inability to provide all the water needed all the time, we will be required to follow suit with the Portland contract. Commissioner Manning questioned the status of Lake Oswego's water. Mike Miller stated that they are back on line and we are taking another 2 mgd from TVWD. We did sell water to the City of Tualatin for a twenty-four hour period during this crises. Commissioner Manning also questioned the effect of the conservation measures? Mike Miller stated that we seen a .5 mgd drop in consumption. The Board discussed the storage capacity of our system (22 mgd) and the fact that we could probably last one week with the wells and the reservoirs. During this time period, we were able to continue to bring in 1 mgd through the wells. A motion was made by Commissioner Manning to go into Executive Session in accordance with ORS 192.660 relating to real property transactions which was seconded by Commissioner Hunt and passed unanimously. • Intergovernmental Water Board Meeting 2-14-96 Page 2 The: regular meeting was reconvened at 6:08 p.m. Commissioner Hunt discussed his concern with the report from Murray Smith `• last year and the recommendations of that report. Commissioner Hunt continuedyto .say that since they were experts in the field, their report did not reflect .the- facts. Mr. Wegner stated that when the matrix and research was completed by Murray Smith it was close between Lake Oswego, Portland and the Regional Willamette study and at that time there was a great interest in securing a partnership with someone and own a portion of a system and Portland at that time was saying that they were not going to supply us with water. Mr. Wegner continued to say that based upon the information a couple of years ago, Lake Oswego was the best bet and since that time a lot has happened within the region. Mr. Monahan stated that when that report was submitted it was accurate for the information that was available at that time, although he did feel that the criteria they (Murray Smith) used needed some more weighing. Mr. Monahan stated that they did give good advice and they have been flexible in modifying their position and' have been supplying assistance with the new information that has come forth. Mr. Monahan stated that maybe a new recommendation should be asked for based upon the current information. 7. Director's Report Mr. Wegner stated that prior to the April meeting, Mr. Monahan and himself 1. can meet with Murray Smith and weigh the criteria and come back with a status report on the water study. Mr. Scheiderich stated this should include who needs capital improvements, and who has capacity that may be for sale. Commissioner Froude questioned the status of the rate study? Mr. Wegner stated that there was a memo from Mr. Lowry distributed which stated that CH2M Hill is waiting on additional information from the staff` and they are planning on attending the April meeting with a status report. This rate study will take the current information available and the model will enable us to put in various figures. Mr. Wegner stated that the next big project within the District is the widening project on Durham Road. We will be moving some meters and doing some service work in that area. Mike Miller stated that this is a State funded, County project and will continue until Fall or late Summer. The District will not be moving a main but will be doing service work. Mr. Wegner stated that the water system was able to withstand all the • disasters of the past month between high winds, power outages and flooding. Intergovernmental Water Board Meeting 2-14-96 Page 3 Mr. Wegner stated that at next months meeting, we will provide the proposed budget, rate study with CH2M Hill, and Murray Smith will make a presentation on Menlor Reservoir Site capital project. Commissioner Manning requested the • proposed budget being sent out with the packet so the Board will have time to review. The March meeting will be on March 13, 1996. 8. Non Agenda Items Commissioner Froude questioned the Greenspace Program that Metro is funding. The CIT and the County CPO have had presentations from both County and the City and the County is looking at property on Bull Mountain (#19 on map) next to Menlor Reservoir site. How much property does Tigard Water District own? Mike Miller stated that the Water District owns 11 .04 acres, with an anticipated seven or eight acres needed for the site. Commissioner Froude questioned what would .the process be if the County is interested in available land? Mr. Wegner stated that we would not want to commit to any available land until the Menlor Site is complete, but they would need to approach City staff and go through the IWB and then to the respective agencies. Chair Scheiderich questioned the status of the facility use? Mr. Monahan stated that we are currently waiting for information back from King City and the Tigard Water District on what, if any, options they see are available to the • City to lease or purchase a portion of the building. The City is continuing to do a space analysis and developing alternatives to take to Council. Mr. Monahan continued by saying that all agencies have been requested to state their position on a lease or sale of facility interest. Commissioner Hunt stated that since the City is looking at long term needs, the hope is that the lease option would be very long term. Mr. Monahan stated that if the City moves more facilities to the Water building, we may look at expansion of that facility and we would need to negotiate the percentage ownership interest which would be in the current structure but any new expansion would be the City's investment. Chair Scheiderich stated this might involve a dilution of the percentage interest. Commissioner Budihas stated that King City Council questioned not only the value of the facility but the value of the land? Mr. Monahan stated that the figures submitted to City of King City did not include land value. 9. Adjournment Commissioner Manning made a motion to adjourn which was seconded by Commissioner Hunt and voted upon unanimously at 6:30 p.m. • Intergovernmental Water Board Meeting 2-14-96 Page 4 .%rraq Smith bssociates,lnc.

The purpose of this letter is to present the findings and recommendations resulting from this work. Background The City of Tigard's existing water distribution system contains two major pressure zones served by gravity from storage reservoirs. These zones are the 713-foot and the 410-foot pressure zones. The 410-foot pressure zone includes eight existing water storage reservoirs. In September of 1986 a report titled "Water Supply Plan for the Bull Mountain Area" was prepared for the Tigard Water District by Gilbert R. Meigs, Consulting Engineer. This plan recommended the construction of two additional reservoirs to-serve the 410-foot pressure zone. The plan recommended that one of these reservoirs have a capacity of 2.5 million gallons (mg) and be constructed,at the Menlor site. A vicinity map showing the location of the Menlor site is attached as Mr. Bill Monahan Noverriber 17, 1995. Page 2 • Figure.A. The plan recommended that a second reservoir, with a capacity of 1.0 mg and an overflow elevation of approximately 470-feet be constructed at the Menlor site as well. The Tigard Water District completed elements of the conditional use permit application for the construction of these reservoirs at the Menlor site in 1989. The 1986 plan also recommended the construction of additional reservoirs on the south side of Bull Mountain. These proposed reservoirs include a 2.5 mg,reservoir, with a overflow elevation of approximately 410 feet, recommended for construction on SW 150th Avenue and a 2.5 mg reservoir with an overflow elevation of approximately 550 feet recommended for construction near SW 144th Avenue, north of SW Beef Bend Road. Water System Planning Review As part of this preliminary,design effort, elements of the City's current water system plans were reviewed. This review included confirming planned reservoir volumes, overflow elevations, reservoir depth and diameter requirements and other relevant water system planning data. • The planning data review included an evaluation of proposed reservoirs and pressure zones recommended in the 1986 Plan. As previously stated, this plan recommended that two reservoirs be constructed at the Menlor property. Findings Pressure Zone Layout The water system planning review found that the proposed pressure zones and storage reservoir overflow elevations recommended for the south side of Bull Mountain differed from those proposed on the north side of the mountain. Specifically, ground elevations on the south side of Bull Mountain between approximately 300 and 450 feet are proposed to be served from a future storage facility with an approximate overflow elevation of 550 feet. Areas with these ground elevations near the proposed Menlor Reservoir site, on the northwesterly side of Bull Mountain, are proposed to be served through pressure reducing facilities from the City's 713-foot pressure zone and by gravity from the proposed 1.0 mg reservoir at the Menlor site with an approximate overflow elevation of 470 feet. Based on the planning data review it appears that constructing a reservoir with an approximate overflow elevation of 550 feet on the north side of Bull Mountain, Mr. Bill Moriahan November 17, 1995 Page 3, preferably near the Menlor site, will provide the City a more efficient pressure zone layout than that provided in the 1986'P1an. Construction of this reservoir would eliminate the need for the construction of the 1.0 mg reservoir originally planned at the Menlor site with an overflow elevation of approximately 470-feet. With the construction of a 550-foot overflow elevation reservoir, the pressure zone service limits for the north side of Bull Mountain will correspond to that proposed for the south side of the mountain in the 1986 Plan. A preliminary review of areas adjacent to the Menlor property indicates that there may be a suitable site for a new reservoir, with an overflow elevation of approximately 550 feet, immediately to the east of the Menlor property. City staff are presently reviewing the availability of this property for potential acquisition by the City for the construction of a new reservoir. The City has acquired property for the.proposed reservoir on SW 150th Avenue but has not yet acquired the land needed for the proposed reservoir on SW 144th Avenue. The need for other storage reservoirs and pump stations at the Menlor site depends on the outcome of'land acquisition and siting issues related to the proposed 550-foot overflow elevation reservoirs). Proposed Reservoir Capacitv As presented above, previous planning for Menlor site proposed a 2.5 mg reservoir serving the 410-foot pressure zone. Discussions with City staff indicate that an older, existing, 0.8 mg reservoir-serving the 410-foot pressure zone and located approximately one mile east of the Menlor site is scheduled to be removed from service in the near future. This loss of storage capacity in this pressure zone can be replaced.through the addition of approximately 0.8 mg to the proposed 410-foot Menlor.Reservoir. This results in a proposed reservoir capacity of approximately 3.3 Mg. The recommended capacity of the proposed reservoir has been rounded to approximately 3.5 mg. Preliminary Site Layout A preliminary proposed development plan was developed for the Menlor site to accommodate the proposed 3.5 mg reservoir. This site plan is attached as Figure B. The plan illustrates the proposed reservoir, access road, existing and proposed water mains, valve vaults, drainage and overflow piping, fencing and landscaping and general site layout. Final slopes, grades and cut and fill requirements will depend on the results of future geotechnical investigations. Mr. Bill Monahan November 17, 1995 Page 4 • The layout of facilities on the proposed site plan accommodates future construction of pumping and piping facilities south of the proposed reservoir that may be required should other_water:storage or pumping facilities ultimately be constructed on or near this site. The-proposed site layout would also provide opportunities for alternate uses or sale of thd'remaining property should no additional facilities be constructed at the site. Site Access Three site access alignments onto the Menlor property were evaluated. These access points are illustrated on Figure B as the Tract "G" access, the Sunrise Lane access, and the Round Tree Estates access. The Tract "G" access provides entrance from SW Scholls Ferry Road to the site through an existing subdivision, called Bull Mountain Meadows, located northwesterly of:the Menlor property. Use of this access would require that construction traffic be routed through this subdivision. Development of this access would, however, minimize the amount of the site developed as an access roadway. The access onto the Menlor property from this subdivision is between two existing homes through a utility corridor owned by the City. • The. Sunrise Lane access provides access to the site from the southeast. Development of this access would require that construction traffic be routed onto Sunrise Lane, a paved two lane road maintained,by Washington County. Discussions with City staff indicate that the County may have objections to the use of this roadway for heavy construction traffic. Use of this access would also require that additional access easements.and/or land be acquired along an existing utility corridor that connects the Menlor site to Sunrise Lane from the southeast. Development of this access may also ultimately reduce the amount of the site available for water facilities or for future property partition and/or sale since the access roadway would cross a major portion of the unused property. The.preferred site access alignment, identified as the Round Tree Estates access, provides access from the north and is the most direct connection of the Menlor property to SW Scholls Ferry Road. This access requires the extension of SW 154th through an undeveloped property. This property maybe subject to future development. City staff are presently engaged in discussions with this property owner concerning utility easements. These discussions should continue and be expanded to include consideration of the future reservoir access. Development of this access would also minimize the amount of the site developed as an access roadway. Mr. Bill Monahan November 17, 1,995 . Page 5 • Connection Piping Connecting piping to the proposed reservoir and between existing piping is illustrated on_the site plan: It is recommended that the proposed reservoir be connected with a 16-inch diameter main to an existing 16-inch diameter transmission main in SW Scholls Ferry Road. This existing transmission main serves the 410-foot pressure zone. Also illustrated on the plan is connecting piping between existing 470-foot pressure zone piping. Connection of this piping through the project site improves water circulation within this pressure zone. Confirmation of pipe size assumptions should be completed prior to final design efforts. Transmission System Hydraulic Capacity Discussions were held with City staff to review existing water system operations, specifically fill and draw operations of the existing storage reservoirs that serve the 410-.foot pressure zone. Through these discussions and through a review of existing City water system telemetry data it was found that the existing transmission system may not have adequate hydraulic capacity, under certain demand conditions,to fill the proposed Menlor Reservoir. • Recommendadons It is recommend that the City take the following actions: 1. Proceed with the conditional use permit application process for a proposed 3.5 mg ' reservoir with an approximate overflow elevation of 410 feet at the Menlor site. 2. Confirm that the Round Tree Estates access can ultimately be developed to the satisfaction of the impacted property owner(s). 3. Following the issuance of a conditional use permit for the construction of the proposed reservoir it is recommended that final design efforts begin. 4. Concurrent with the beginning of the conditional use application process it is recommended that a hydraulic analysis be completed of the 410-foot pressure zone's transmission system to determine those improvements required to allow the' transmission system to adequately supply water to the proposed reservoir. This modeling effort should also confirm the connecting pipe size assumptions for the proposed reservoir. • Mr. Bill Monahan November 17, 1995 Page 6" 5. It is recommended that the City immediately begin a site selection and acquisition process for the proposed SW 144th Avenue Reservoir and for a 550-foot overflow elevation reservoir near the site of the proposed Menlor Reservoir. Following the resolution of property availability and acquisition issues related to these future reservoirs, it is recommended that the need for other water facilities at the Menlor site be re-evaluated. Project Cost Estimates A project cost estimate was developed for the proposed 3.5 mg reservoir. The estimated project cost for this reservoir is approximately $2,960,000. A break down of this estimate is provided as Exhibit"C". This�project cost estimate is an opinion-of probable costs. Actual costs will depend on geotechnical findings, final project,scope and design, construction market conditions and other factors. This project cost estimate is based on construction of a prestressed, partially buried, concrete reservoir by private contractors. Schedule • Recommendations numbered 1 and 4 should be undertaken immediately and concurrently with the understanding that transmission improvements developed through the hydraulic analysis should be completed before the proposed Menlor Reservoir is brought into service'. Final design.efforts may begin prior to the issuance of the conditional use permit once the certainty of obtaining the permit is known. We appreciate this opportunity to assist the City. Please do not hesitate to call if you have any questions concerning our review, findings or recommendations. Sincerely, MURRAY, SMITH & ASSOCIATES, INC. PRQ�� i GIN£ 15039 r Chris H. Uber, P.E.
