3. PROGRAM PURPOSE (REVIEW)
Documents,prepared for this special meeting,are on file in the council meeting packet.
• Council Report—dated November 9,2011, from Joel B. Komarek,Project Director for the
Lake Oswego-Tigard Water Partnership regarding the Lake Oswego-Tigard Water Supply
Expansion Project—Implementation Update.
• PowerPoint Slides—Lake Oswego-Tigard Water Partnership—Water Program Update Joint
Council Meeting—November 14,2011.
Lake Oswego City Engineer Komarek presented the staff report.
• Work commenced on the project in 2008,when the communities of Lake Oswego and
Tigard entered into an Intergovernmental Agreement to jointly plan, finance,construct and
operate an expanded water supply system for the benefit of both communities.
• Water program overview of existing facilities:
o Clackamas River intake is located in the City of Gladstone. The water is pumped
across the Willamette River through a 27-inch diameter pipeline to the treatment
plant located in West Linn.
o The current capacity of the treatment plant is 16 mgd.
o The treated water is pumped through a 24-inch diameter finished water pipeline to
the west side of the City of Lake Oswego to the terminal reservoir,Waluga
Reservoir.
o Tigard has a connection to the Waluga Reservoir,which is pumped into the Tigard
community's distribution system.
o The existing system was built in the mid- to late-1960's.
• Reviewed a concept rendering of River Intake Pump Station (RIPS) that will replace the
existing station. This rendering was presented to the City of Gladstone Planning
Commission several months ago as part of the conditional use and design review process.
This concept was approved by the Gladstone Planning Commission and is being used for
final design preparation. The land use process for the station is complete. Currently
environmental permitting efforts are underway.
• Reviewed a map of the wide range of alternatives evaluated for the raw water pipeline system
(intake) for the water treatment plant.

• Reviewed the finalized alternatives for the raw water pipeline:
o Preferred option is the Hull Avenue to Mapleton Drive alignment.
o Another option is the Meldrum Bar Park to Mary S.Young Park if an issue arises
that would preclude the preferred option.
• Reviewed the raw water pipeline considerations (Slide 7).
• Reviewed preliminary and current site plans of the water treatment plant(Slides 8 and 9).
• Reviewed artist renderings of vantage points of the water treatment plant site.
• Reviewed the preliminary design considerations for the water treatment plant (Slide 15).
• Revised schedule predicts the plant will take about 28 months to build (originally anticipated
24 months).
• Reviewed the current alignment and work needed soon for the finished water pipeline
connecting the water treatment plant to the Waluga Reservoir(Slide 15).
• Reviewed the recommended Waluga Reservoir 2 site location for a 3.5 million gallon tank
that will provide storage not only for Lake Oswego but for Tigard from which to draw for
the new Bonita Pump Station.
Tigard Public Works Director Koellermeier commented on Slides 20 and 21 for the new Bonita
Pump Station:
• Reviewed that the best site has been located for a reservoir. The station will be relocated
from the existing site,which was too small.
• Reviewed the features of the station.
• Reviewed plans to address storage and water age issues.
• Reviewed the supply connections,work done to acquire property,and plans to begin
construction in April 2014,which is later than originally planned but will mitigate cash flow
compression.
Lake Oswego City Engineer Komarek:
• Reviewed the updated schedule (Slide 22),which was revised to better manage the resources
and cash flow.
• Reviewed that the plans are for the project to be completed well in advance of July 1,2016.
• Reviewed the financial status (Slide 23). The partnership has spent a total of a little over$13
million.
• Reviewed the key events/issues for the next six months (Slide 24). The plan is to use an
alternative delivery method to procure the services of a horizontal directional drilling(HDD)
contractor,as opposed to a conventional design/bid/build delivery approach—this process
will begin the first quarter of 2012.
• Reviewed the status of the water rights appeals process. First briefings to the appeals court
are due later in November.
• Reviewed that both Tigard and Lake Oswego will be positioning themselves and looking for
their first bond issues: for Tigard,February 2012 bond issue; for Lake Oswego,a late
second or early third quarter bond issue.

® Communications Director Heisler:
• Reviewed the 2011 public outreach priorities (Slide 25).
• Reviewed target audiences and methods (Slide 26).
• Reviewed public outreach and communications in efforts to create broad community
support. (Slides 27 and 28).
Questions/Comments:
• Councilor Jordan asked how much energy would the solar panels produce and whether it
makes sense to do more than what is required by state law. Lake Oswego City Engineer
Komarek said he did not have the answer about how much energy the solar panels will
produce as the panels have not been designed. He said they made an estimate using the
administrative rule as to what"one percent"means in terms of the investment amount. One
percent equals$250,000. From that the engineers determined the number of panels that can
be purchased and located on the treatment plant roof. At this time,the plans are for the
required one percent,although it is possible more could be done. Councilor Jordan said it
would be interesting to know what the trade-off is and if there is capacity.
• Councilor Jordan requested information about the decision to procure a horizontal
directional drilling(HDD) contractor,rather than using a design/bid/build process. Lake
Oswego City Engineer Komarek said for all facilities,other than the two HDD crossings,
construction will be approached as a conventional design/bid/build with prequalification of
contractors bidding on the major elements of work. The HDD projects are specialized and
there is a smaller pool of qualified contractors. The partnership wants to make a decision
based on factors that includes price. They want to select the contractor that brings the best
combination of technical expertise,qualifications and price. They will use a competitive
proposal approach to procure services.
• Councilor Jordan commented on a remark by one of the Gladstone City Council members
regarding drilling under a community garden if the preferred alternative alignment for the
pipeline is used. During discussion it was noted the preferred alignment would not affect
any garden areas.
• Councilor Wilson referred to the 30 percent cost estimates due in the first half of 2012. He
asked when was the last cost estimate done—have there been interim cost estimates?Lake
Oswego City Engineer Komarek said the last program cost estimate was in November 2010.
For purposes of rate setting and revenue requirements,this estimate (cash flow forecasting)
was updated in March 2011 and again in September 2011,to make sure both communities
were collecting sufficient revenue to support debt issues for 2012. When the schedule
shifted,cash flow was reanalyzed to make sure the timing of the revenues was appropriate to
the expenditures. The forecasts utilized many of the same assumptions used to develop the
November 2010 estimate. When the 30 percent design development estimates are received
from the design firms, forecasting can be predicted using the updated information.
• Councilor Moncrieff followed up on Councilor Jordan's comments to support use of solar
energy. She referred to the report that the existing water plant consumes about 55 percent

of the electricity used in Lake Oswego and energy costs have risen by 17 percent over the
past year. She said she supports any efforts to minimize operating costs and to use the best
technology. Lake Oswego City Engineer Komarek agreed this was a good point and said
they were looking into a variety of sustainable practices for the plant. Primary objectives for
the overall project were for a long operating life with low lifecycle costs. In addition to solar
energy,they are also exploring opportunities for heat recovery. The plant design team
includes a special group with a focus on sustainability. There has been discussion to go
about the project so if the decision was made to seek a LEED (Leadership in Energy and
Environmental Design) certification,it would be possible. Tigard Public Works Director
Koellermeier said installation of solar panels has to be balanced with land use issues,such as
buffering and screening. He referred to other sustainable features including natural lighting
and things learned by visits to other plants—there will be many opportunities to institute
sustainable practices in a variety of ways.
• Councilor Kehoe noted his support of the sustainable practices under discussion tonight.
He urged a little caution regarding solar use noting his experience that,in general,solar
panels do not generate enough electricity to justify the cost unless there are tax subsidies.
He noted the need to keep the total cost of the project as low as possible for the citizens.
• Tigard Council President Buehner said she understands that over the last year there was an
extensive value engineering process to evaluate the possibility of different ways to approach
components of the plant or other parts of the project. She asked if Lake Oswego City
Engineer Komarek received information for positive changes that might make the project
more efficient and save money. Mr. Komarek said one of the recommendations for the
Plant was to consider using a somewhat new technology for water treatment that would
dewater the silts and clay materials produced from the treated water. The original
assumption was to use centrifuges to dry out solids;however,there is the possibility to use a
screw press. While a screw press is used throughout the wastewater industry,there is little
information about its use for drinking water. They have asked screw press vendors if they
would be interested in a pilot test on the types of solids generated in the water treatment
plant. They have talked with the City of Wilsonville to determine if they would be
interested in facilitating the pilot project since they produce the same kinds of solids that will
be produced in this plant. On a life cycle basis,the screw press has a better return on
investment than the centrifuges,but they require a larger building to house them. The screw
presses are easier to operate and maintain.
• Councilor Henderson asked for additional information on potential geotechnical problems.
Lake Oswego City Engineer Komarek said they recently completed investigatory borings
and analyses of the information for the plant site. About 25 feet below the site,there are
soils that the engineers say are potentially liquefiable in a seismic event. This needs to be
considered when designing the project structures,particularly those that are water bearing,so
the amount of settlement that would occur after construction and a post-seismic event
would be minimized. This translates to the type of foundation to be constructed and they
are exploring options at this time including examining how this will impact costs.
• Councilor Wilson questioned whether a contractor should be procured early on to flush out
some of the constructability issues. Lake Oswego City Engineer Komarek said the team

talked about this at length and there was a time when an alternative delivery was under
consideration for the water treatment plant. In the end,they decided there was not a
compelling reason for this plant site to move forward with alternative delivery. With a
robust prequalification process,they can manage the risk. In response to a question from
Councilor Wilson,Lake Oswego City Engineer Komarek said he did not have a cost
premium figure for a compact footprint versus the more spread out earlier version.
Generally,it might mean that they will have to construct a new structure adjacent to an
existing structure that will have to remain in service. He agreed there is a cost to the
compact footprint,but no cost comparison was done.
• Public Works Director Koellermeier reported that the design standards with regard to
settlement are rigid.
• Councilor Gudman asked about the response from the West Linn neighborhood when the
design features of the water treatment plant were presented. Ms. Heisler said they received a
lot of positive comments. Some people appeared to be happy with the compact footprint
since the structures would be located farther away from their property and with the
additional landscape buffers that are planned. There remains a group of people who would
prefer that the plant be moved to Lake Oswego.
• Councilor Gudman asked about the discount rate used for the analysis. Lake Oswego City
Engineer Komarek said they have been carrying a 4.4 percent discount rate for all of the net
present value analysis work.
4. WATER RIGHTS UPDATE
Lake Oswego City Engineer Komarek reviewed:
• The record generated by the contested case hearing in March 2010 was consolidated and
entered into the record at the appellate court.
• A briefing schedule was set by Judge Brewer. Briefings are due November 28.
• It is anticipated that the petitioner,Water Watch,will be requesting an extension to the
submittal date for their briefing. If granted,the extension period can range from 30-60
days.

5. SCHEDULE UPDATE/ISSUES
Lake Oswego City Engineer Komarek reported they are on schedule. Some things are being
moved around to manage cash flow and resource allocations. They still anticipate a completion
date well ahead of July 1,2016.

6. QUESTIONS/COMMENTS
• Councilor Jordan said she is impressed with the new water treatment plant footprint—it
is a positive step.

• Mayor Dirksen suggested another joint meeting around July. This would be about the
time the 30 percent design review will be available for evaluation. Mayor Hoffman
agreed that Lake Oswego would host the next meeting.
• Tigard Council President Buehner commented that the Oversight Committee members
have had an opportunity to learn about various kinds of filtration systems. The new
flocculation process is part of the reason the treatment plant footprint can be reduced
and should result in cost savings.
• Lake Oswego Mayor Hoffman said he attended the National League of Cities
conference last week. He attended a presentation facilitated by a person from the Clean
Water America Alliance. The subject included information on a change in the way
people view water. Points brought forward by the speaker included:
o To be sustainable,we have to build systems that last.
o New regulations are forthcoming and he advocated including the full true cost of
water. Most cities'charges for drinking and wastewater represent one percent or
less of the median household income. However,EPA is suggesting that to catch
up with infrastructure,a reasonable monthly charge would be two percent for
wastewater charges and two percent for drinking water. This cost is lower than
services to provide television,cell phones or energy.
o Children should never fear that they will not have glass of clean water.
o In the 1950's there was a nationwide construction of water pipe projects with a
life expectancy of 50 to 75 years. In the 1970's and 1980's there was a lot of
construction of water treatment plants throughout the country,with a 25 to 50
year life cycle.A new wave of infrastructure investment is needed. $250 billion
will be needed to replace water infrastructure nationally.
o Local entities now fund 90 to 95 percent of infrastructure.
o In the USA,a water main breaks every two minutes.
