INTERGOVERNMENTAL WATER BOARD
MEETING MINUTES
March 9, 1994
Board Members Present: Paul Hunt, Lynda Jenkins, Peggy Manning and George Morgan
Board Member Absent: Bill Scheiderich
Guests Present: Beverly Froude and Jack Polans
Staff Present: John Acker,Leslee Gemmill, Mike Miller, Pat Reilly, Randy Volk and
Ed Wegner
1. Call to Order
City Administrator, Patrick Reilly welcomed those present and at 5:30 p.m., brought the
meeting to order. He informed the Board the fifth member, Bill Scheiderich was unable
to attend due to a prior commitment.
2. Approve February 23, 1994 regular meeting minutes
Approve February 28, 1994 special meeting minutes
Lynda Jenkins motioned to approve the meeting minutes as submitted and Peggy Manning
seconded the motion. A voice vote was taken and the motion passed unanimously.
3. Water Supply Plan Update
Patrick Reilly introduced Mr. Harold Murray, President of Murray, Smith and Associates,
Inc. Mr. Murray introduced Chris Uber, Project Engineer with the firm and said they were
both involved in the Phase 2 Regional Water Supply Plan so have good insight in the
regions water supply.
Mr. Murray explained to the Board Tigard's agreement with Murray, Smith and Associates
provides for professional engineering services necessary to complete a water supply update
plan. Mr. Murray said presently, Tigard contracts with the City of Lake Oswego and City
of Portland for its water. Approximately 97% of Tigard's water now purchased is surplus
from the City of Lake Oswego and the rate is established by the City Manager of Lake
Oswego. Approximately 3% of Tigard's water is purchased from the City of Portland. The
25 year agreement with Portland was signed in 1983.
After evaluating potential water supply sources including South Fork Water Board, City of
Tualatin, the Joint Water Commission and a new Willamette River source, Mr. Murray
indicated that at this point,the existing water providers capable of supplying water to Tigard
include the Cities of Lake Oswego, Portland and the Tualatin Valley Water District. Each
of these three water providers are currently evaluating improvements required to their
systems in order to provide water to Tigard. Mr. Murray informed the Board that the
completion of the project may be delayed as a result of not yet receiving the necessary
information from these entities.
INTERGOVERNMENTAL WATER BOARD MEETING - March 9, 1994 - Page 1
Mr. Murray reviewed briefly the means by which the cities of Lake Oswego and Portland supply
water to Tigard. Portland water supply comes from a protected watershed, is chlorinated and not
filtered and Lake Oswego provides a higher quality water as they have a water treatment plant -
both meet federal standards.
• Patrick Reilly asked Mr. Murray to clarify Lake Oswego's position regarding supply
of water to Tigard.
Mr. Murray responded that to the best of his knowledge, the City of Lake Oswego
is faced with a big expense if they were to continue providing water to Tigard and
they don't want to lose the revenue. He continued saying Tigard's share of the
necessary improvements for Lake Oswego to continue providing water to the Tigard
service area is estimated to be $24 million.
• George Morgan asked Mr. Murray if a 90-120 day deadline for completion of the
project is reasonable.
Mr. Murray answered that an extension would be needed to complete the study.
• Lynda Jenkins asked about the status of the long range population data.
Mr. Murray indicated John Acker, City of Tigard Associate Planner, has provided his
firm with these estimates.
• Paul Hunt asked about the likelihood of getting water rights from the Willamette
River.
Mr. Murray explained that his firm just completed a water right analysis of the
Willamette for the Regional Water Study and every indication says water rights will
not be available. However, water is available from storage and the dams on the
Willamette are owned by the Corp of Engineers. The Corp of Engineers do not have
authorization to supply municipal and industrial water and it's a complicated process
to get re-authorization. He further explained this process is very complicated as is
the issue of water rights.
• Peggy Manning asked Mr. Murray his opinion on Region 2040 and if he envisions
one future regional water district.
Mr. Murray responded that Metro's 2040 plan is strictly a concept of landuse and will
be used to guide the region. Water supply to meet the future demands will be as a
result of the Phase 2 study. A big push for everyone to consider combining efforts
is evident however difficult due to the political entities involved, specifically those
entities that own water rights.
• Peggy Manning asked about Lake Oswego and negotiations for a minimum and
maximum volume commitment.
INTERGOVERNMENTAL WATER BOARD MEETING - March 9, 1994 - Page 2
Mr. Murray responded that he would recommend Tigard commit to a portion of
Lake Oswego's debt and agree to pay off its share annually. He explained to the
Board the term "cost of service". In conversations between Lake Oswego and
Murray, Smith & Associates, Lake Oswego has indicated they'd be able and willing
to serve Tigard on the basis of cost of service.
• George Morgan asked about the significance of the information needed to report to
the City of Tigard and whether it might require a deferral as time gets closer for the
forecast of regional information. He also asked if an interim short term contract for
water would be preferred over the current arrangement and would it entail the
involvement of other jurisdictions on a sub regional basis.
Mr. Murray said Tigard currently has a backup source of water via a long term
agreement with Portland. He explained the current contract with Portland
specifically identifying the penalty terms.
Using maps, Chris Uber presented to the Board an overview of Tigard's existing system.
Mr. Uber said Tigard currently has in reservoirs 20.88 million gallons of water. In addition,
he presented to the Board a water system hydraulic profile (attached) developed as part of
the Regional Supply Plan, Phase 2. This schematic showed the regions major storage,
transmission, pumping and supply facilities. He reviewed the process of getting Lake
Oswego and Portland water to the Tigard service area and he talked about the advantages
of gravity supply.
• Lynda Jenkins asked Mr. Murray about aquifirs.
Chris Uber and Harold Murray responded that the Regional Phase 2 Plan is looking
at an alternative plan - A.S.R. (Aquifir Storage and Recovery). A.S.R. uses
underground aquifirs as a storage vessel, pumping treated water down into the
storage vessel during high flow periods and taking water out again during the
summer. It is a new idea in this area and has been used in other parts of the country
and is certainly a viable option. The whole subject of wells is being scrutinized -
whether or not they are safe and can they be protected. All possible avenues will be
looked at in the regional study before any decisions are made.
After a brief discussion regarding a short term water source while investigating and negotiating for
a long term water supply, Mr. Murray reminded those present that any existing, older system will
be able to supply water less expensively than a new venture.
Chris Uber talked about the daily capacity of Lake Oswego and the combined demand of Lake
Oswego and Tigard. The current capacity of the treatment plant is 16.1 gallons per day and during
the last hot day, the two cities combined demand was over 20 million gallons. As the populations
increase, the improvements recommended in Lake Oswego's water master plan will double the
capacity therefore, the $24 million cost. Lake Oswego has opted to hire an outside engineering
consultant to complete an in-depth review of the 1988 Lake Oswego Water Master Plan
recommendations for the supply of water to Tigard from Lake Oswego. Ultimately, the entire
region will need to expand their facilities and water rates will increase.
INTERGOVERNMENTAL WATER BOARD MEETING - March 9, 1994 - Page 3
• Patrick Reilly responded to a comment from Paul Hunt regarding the contract with
Lake Oswego. He said the contract expired last year and Lake Oswego has agreed
to continue to supply Tigard's service area with water to the end of this calendar
year.
There was discussion regarding the automatic renewal of the contract when it wasn't
signed last year.
Patrick Reilly informed the Board the contract has been assigned to the City of
Tigard and extended for one year under its current terms.
After a brief discussion, the Board authorized Patrick Reilly to request an extension from the City
Council, of the deadline for the update of the water supply plan.
• George Morgan asked Mr. Murray about his firms role in the Regional Study. Mr.
Murray responded Murray, Smith and Associates, Inc. is a subcontractor for
Montgomery Watson responsible for the water treatment and transmission facilities.
Murray, Smith and Associates, Inc. is doing the engineering work for transmission
facilities interties, the regional system and reservoirs. Secondly,his firm provided the
map detailing the regions infrastructure to the Study. Phil Smith, of Murray, Smith
and Associates has just completed a water rights analysis on all the water sources.
After further discussion with Mr. Murray about the regional study timelines and available options,
the Board complimented Mr. Murray and Mr. Uber on their informative presentation.
4. Existing Long Term Capital Improvement Program
This item will be put on the next meeting agenda.
5. There was a brief discussion regarding the agenda for the next meeting scheduled for March
23, 1994 and the meeting adjourned at 7:20 p.m.

MEMORANDUM
CITY OF TIGARD, OREGON
To: Patrick J. Reilly,City Administrator
From: Michael Miller, Water Management Analyst
Date! March 2, 1994
Subject! 5-Year Capital Improvement Plan
In preparing the current 5-year Capital Improvement Plan (CIP), we hired Mr. Gilbert
Meigs of Economic and Engineering Services, Inc., who also authored the engineering
studies in 1971, 1986, and 1990.
From those engineering studies and discussions with water staff to ascertain projects that
were completed during the last fiscal year; projects that are to be or have been completed
and financed by developers; and the developmental trends within the service area, a
comprehensive prioritized plan has been developed to meet the water demands of the
service area now and into the future.
Through the years the 1971 engineering study has proven to be the most comprehensive
and reliable of the studies, and is the basis for most of the major water supply projects.
This study recommended the construction of the 10 million gallon (mg) reservoir (SW
125th Avenue and SW Bull Mountain Road)from which all the other reservoirs would be
served, as well as the construction of 30-inch water mains to Lake Oswego and Portland
so that future supply demands could be met. The 1971 study also recommended that 23
mg of storage be constructed by year 2000.
Of these projects the 10 mg reservoir; the equivalent to a 30-inch transmission main (24-
inch and 16-inch parallel mains)to Lake Oswego; and 21 mg of storage capacity has been
completed. The full 30-inch equivalent to Portland has been completed from SW
Tiedeman Street and SW Greenburg Road to Highway 217, but from that point to Bradley
corner, a 16-inch transmission main connects us to Portland. The current 5-year CIP calls
for the construction of the 2.5 mg reservoir, south of SW Scholls Ferry Road, to be
constructed during the 96-97 fiscal year, which will surpass the 23 mg of recommended
storage.
In December 1990, the Agency implemented System Development Charges (SDCs) as a
way to provide the means to finance future capacity increasing projects without having to
borrow funds. The objective of SDCs is not merely to generate money for the Agency,
but to ensure that a fair and equitable financing solution is available to support needed
capital improvement additions due to growth. These capital improvement additions are
those which increase the system capacity such as new storage reservoirs, pumping
stations, transmission pipelines, pressure reducing valve stations, and other major
distribution pipelines.
The income for SDCs comes from water meter installations. Approximately 60% of the
water meter sales revenue are directed to the SDC Fund, while the remaining 40% are
divided and deposited into the Water General Fund budget line items of water meter sales
and SDC reimbursement. The reason SDCs are important is that every project listed on
the CIP is a capacity increasing improvement and can be funded by SDCs.
As with any management tool the current CIP lists the capacity increasing improvements,
including the estimated cost and timing. It also allows different alternates so that changes
of events may be accommodated and the specifics of the CIP may be reshaped as the
years pass. The CIP has been updated and altered to some degree every year since 1990
for this very reason. This is not to say that we are changing the overall CIP on a whim,
but rather we are altering it to take advantage of the changing needs of the service area.
One example of this is the 24" transmission pipeline along SW Greenburg Road. This
project was put on hold during the 92-93 fiscal year in order to save funds because the
SDC fund was smaller than anticipated due to slowing of the new housing market, and
availability of peak water from the Bull Run system was in question.
Another example is the proposed construction of the 2.5 mg reservoir located south of
SW Scholls Ferry Road. In 1990, the original plan called a 2.5 mg reservoir to be
constructed on the southern flank of Bull Mountain, but with the higher growth rate and
demands in the northwest comer of the service area, the CIP was altered to allow the
change in location. Also, in the current CIP, the construction of the 2.5 mg reservoir is
scheduled for fiscal year 96-97. Because funds are available and the demands in this area
have increased significantly, we are requesting that the construction of this reservoir
begin in the 95-96 fiscal year.
With the completion of the Water Supply Study Update by Murray Smith and Associates,
Inc., we will again examine and update the CIP to make the necessary changes to reflect
the recommendations for capital improvements for water source needs.
CAPITAL IMPROVEMENTS PLAN
Funded from System Development Charges
5-Year Plan
June 2, 1993
Fiscal Year 1993-94
Estimated
Project Cost
Pipeline Extension: S.W. North Dakota Street,
S.W. 106th Avenue to S.W. 115th Avenue, 2,600
feet of 12" D.I. pipe @ $41.50/ft. $108,000
Justification: This area of the District system is in need
of reinforcement and looping with medium diameter mains.
This is the beginning of a program that will eventually
utilize existing 12" pipes on North Dakota to complete a
loop between Scholls Ferry Road to Tiedeman Road.
Pressure Reducing Station: Install a buried vault enclosing
pressure reducing valves fitted to the 12" pipe on Sunrise
Lane. Lump sum of $20,000. $20,000
Justification: Until a reservoir is built at elevation
470 on the north side of-Bull Mountain, subdivisions such
as Bull Mountain Meadows which are too high to be served
directly from the 410 "Lone will be served from the
reservoirs at Hi Tor. Water pressure directly from Hi
Tor to these areas would be excessive and reduction is
needed. The District owns land for the proposed reservoir
at elevation 470. A future reservoir (see FY 1995-96) on
the same tract will feed a future pump station that will
fill the 470 reservoir.
1
Fiscal Year 1994-95
Pipeline Extension: S.W. North Dakota Street,
S.W. 115th Avenue to S.W. 121st Avenue, 1,450
feet of 12" D.I. pipe @ $43.00/ft. $62,000
Justification: This completes the S.W. North Dakota
Street 12" loop between Scholls Ferry Road and
Tiedeman Road. Work to begin completion of the loop
is scheduled for FY 93-94.
Fiscal Year 1995-96
Reserve for construction of future 2.5-MG reservoir
for the 410 zone to be located south of Scholls Ferry
Road on District-owned property. $300,000
Justification: The District has adopted a policy of
paying for needed capital improvements from current
revenue. Engineering studies of 1986 and 1990 advised that
to keep up with growth, the District must construct a 2.5-MG
reservoir on the northwest flank of Bull Mountain. Acreage
in the vicinity is under active development. The reservoir
will serve all residents below elevation 350 feet on the
north and northwest side of Bull Mountain. The expenditure
is too large to accrue in one or two years, and the con-
struction reserve begun in prior years will be increased
by FY 1995-96 SDC income.
Fiscal Year 1996-97
Reservoir Construction: 2.5-MG reservoir south of
Scholls Ferry Road on northwest flank of Bull Mountain. $1,300,000
Justification: Engineering studies of 1986 and 1990
advised that to keep up with growth, the District
must construct a 2,500,000 gallon reservoir in the
410 zone south of Scholls Ferry Road. The District
owns property for this reservoir. Additional
pipeline capacity to the north sides of Bull
Mountain is proposed for FY 1997-98.
2
Fiscal Year 1997-98
Pipeline Extension: S.W. 121st and Walnut Street,
from Fonner to 135th Avenue, 5,600 feet of
24" D.I. pipe @ $78/ft $437,000
Justification: In the summer time, No. 3 reservoir will
not fill because the pipelines serving it are too small.
With high growth in this area, along with the availability
requirement for water to be pumped from the 132nd Street
pump station to High Tor, it is deemed important that this
main be installed. Additionally, fire flows are deficient
in some parts of the area. The engineering study of 1986
recommended that this main be constructed. If the City
defers the MacDonald Street project, then this pipeline
would be built.
Note: The balance of income will go into a reserve
for future projects.
Note on Accumulated Reserve for Future Reservoir
At end of FY 95/96, the amount accumulated is estimated to be
$1,118,000. Accrued interest, if any, is not included. The $1,118,000
plus SDC collections in FY 1996-97 are estimated to amount to
$1,418,000. The reservoir is estimated to cost $1,300,000 at the present
time. This does not include an allowance for inflation.
It thus appears that construction could begin as early as the first half of
FY 96/97.

Capital Outlay Projects
Fiscal Year 1994-1995
Pressure Reducing Valve(PRV) station located on the west side of Bull
Mountain between Phase 1 and 3 of Pleasant View Estates $20,000
1,000 feet of 12" D.I. pipe along SW Scholls Ferry Road to complete a
circulation loop between Castle Hill (SW Walnut Avenue)and Pebble
Creek subdivision. $43,000
Possible reconstruction of the 12" D.I. pipe crossing Fanno Creek on SW
Durham Road. Washington County has a road improvement project for Durham
Road from SW Hall Blvd. to SW Upper Boones Ferry Road scheduled during this
fiscal year. Unknown at this time is the projects exact impact on the existing water
system. Preliminary plans available in December-1-993. $8,600
SDC funded projects
1450 feet of 12" D.I. pipe along SW North Dakota Street between SW
115th Avenue and SW 121 st Avenue. This completes the 12" loop between
SW Scholls Ferry Road and SW Tiedeman Road. $62,000
Land and Improvements
Possible purchase of property for a pumping station to transfer water
from the 410 pressure zone to a future 2.5 MG reservoir at elevation
550 feet. This property would be located on SW Beef Bend Road at
SW 137th Avenue. Contingent upon the property being available. $30,000
Clearing and road work at the 1 I acre reservoir site for the construction
of a new 2.5 MG reservoir at elevation 410 feet. $25,000
Permits and Land Use fees for new 2.5 MG reservoir. $15,000
Fiscal Year 1995-96
Possible relocation of 12" D.I. water main along SW Beef Bend Road from
SW 131st Avenue to Pacific Highway due to a Washington County Road
improvement project scheduled for construction during this fiscal year. As of
yet Washington County has not released any preliminary design plans. $70,000
"3
SDC funded projects
Construction of 2.5 MG reservoir at elevation 410 feet on the northern flank
of Bull Mountain south of SW Scholls Ferry Road. $1,300,000
Fiscal Year 1996-97
If SW Garrde Street is not extended to SW Walnut by mid 1996, it will be
necessary to extend 5,600 feet of 24" D.I. pipe from SW Fonner Street and
SW 121st Avenue to SW 135th and SW Walnut Street. The pipelines serving
reservoir No. 3 are not large enough to continue to supply the capacity needed
in this high growth area. This water main would also enhance the ability of the
Agency to supply water to the new 2.5 MG reservoir off of Scholls Ferry Rd.
This project would be funded by a combination of SDC's and General Fund. $437,000
Land and Improvements
Landscaping and fencing at the new 2.5 MG reservoir site. $20,000
