Griffith go through his presentation and then take questions afterwards.
Mr. Griffith presented information with the following outline:
• Rate model changes since January meeting
—� 20-year forecasts
3% vs. 1.2% annual growth comparison
Debt coverage criteria and junior lien debt analysis
—� Updated information: Wholesale water costs for FY 2000/01
Rate impacts of reserve accounts
IWB Meeting Minutes February 9,2000
Page 1
• Rate model features not changed since January meeting
--> Across the board percentage increases
No cost of service rate revision at this time
-� Water supply project startup in 2004
Capital improvement expenses
• Forecasts: No water supply project- Scenario 1
-4 Base case
No water supply project
Continue to purchase water from Portland, Lake Oswego, and TVWD
-a No revenue stabilization fund
-a No CEP or SDC fund reserve
No additional repair/replacement expenditure
• Rate Forecasts-Scenario I
_> Annual rate increases
-4 FY 2000: $1.32/ccf volume charge
-4 Gradual rate increases
-� FY 2004: $1.68/ccf volume charge
FY 2010: $2.28/ccf volume charge
Caution: represents a scenario without capital expense for continued long-
term water supply
• Scenario 2
-� Impact of collecting additional revenues for reserve account accumulation
-� Each additional $100,000/year requires volume charge increase of 3.6
cents/ccf
Applicable for revenue stabilization reserve, CIP reserve, collecting
additional reserves to "buy down" water supply project debt issue
• Scenario 3, 4, and 5
Revenue bond debt service, capitalized bond reserve, 1.20 debt coverage
factor
-� Water purchased from plant; small amount produced from existing wells
1.2% annual growth rate
Scenario 3: $22 M water supply project
Scenario 4: $44 M water supply project
Scenario 5: $88 M water supply project
IWB Meeting Minutes February 9,2000
Page 2
• Rate impacts
All WSP Scenarios: Large increases prior to startup date to meet debt
service and debt coverage requirements
-4 No/minor rate increases from 2004-2010
Debt service cost partially offset by anticipated lower purchase water costs
—� Rate forecasts depend on growth rate, required coverage, project costs and
startup date
2010-2020: Forecast 0%-2% annual rate increases
—� Impact of collecting additional revenues for reserves
—4 Water supply project scenarios
—> Impact of increased system growth
—> Impact of junior lien debt
• Debt Coverage
—> Typically a revenue bond issuance requirement
—4 Reduces risk to bond holders
-� Exact requirements vary
-4 Coverage = (revenues—0&M expenses)/par debt service
1.2 debt coverage factor used as placeholder value
• ,Junior lien debt
--4 "Par debt service" amount reduced; does not include junior lien debt
—4 Effect is more gradual rate increases
Rates eventually reach the same level as with full revenue bond debt WSP
funding
The following questions were addressed to Mr. Griffith:
Commissioner Carroll questioned why revenues were increased so significantly? Mr.
Griffith stated that revenue bonds are presented in such a way to reduce risk to bond
holders, one of which ways is coverage requirement. The bond issuer likes to see the
owner of a system collect more than is required to just cover payment.
Commissioner Scheiderich questioned if larger amount of capital is acquired to apply,
the less debt service the owner would incur. Commissioner Buehner questioned the
basis for the use of the 1.2% growth assumption? Mr. Griffith stated that this is a
Metro generated number. Mr. Miller stated that we are currently looking at about 3%
growth factor, which will come down in the future.
Commissioner Scheiderich questioned the assumptions used for SDC's? Mr. Griffith
stated that assumptions used were $1,475 additional charges based upon some
previously reported information. Current SDC's are at approximately $1,000 which
is slightly lower than TVWD.
IWB Meeting Minutes February 9,2000

Commissioner Drangsholt asked for clarification on a Junior Lien? Mr. Griffith
stated that a junior lien is the order in which debt is repaid.
Mr. Wegner stated that we would need to provide Mr. Griffith some direction to put
together another scenario. As discussed previously, Mr. Wegner stated the Board
would need to discuss how much to be set aside for reserves? This matter can be
decided at a later date and if we are going to break it out with capital, rate
stabilization, or future supply projects. The current retail costs for water is $1.32/ccf.
Currently the capital expenses that have been planned are utilizing the revenues that
are generated with little or none being set aside for reserves. An approximate 3%
increase would generate $100,000 a year for reserves.
It was stated that the last rate adjustment was three years ago but rates were not
changed at that time. The last rate change was in 1993. Commissioner Scheiderich
questioned whether we currently have a lifeline rate? Mr. Miller stated that in 1996
the minimum usage charge was replaced with a cost of service per use (each entity
should have copy of rate model completed by CH2M Hill). This model was set up to
be reviewed every 2-3 years but did not include building reserves for ownership of a
water treatment plant.
Mr. Wegner stated that the new scenario that Mr. Griffith will set up would continue
to include a 1.5 million capital fund to"be spent annually outside the cost of water
delivery service. Mr. Wegner stated that in addition the Board might want to include
reserves for rate stabilization and system improvements in addition to a water supply
project. Commissioner Buehner questioned the amount of impact this year by
Portland increase in rates? Mr. Wegner stated that this year's increase was 1.2
million. Mr. Prosser stated that the impact on rates this year with Portland was a one
time shot. If we added$500,000 to reserves within a two-year period, we would have
a one million dollar reserve. This $500,000 would be a reasonable target that would
increase the current $1.32 rate by .18 cents. Commissioner Scheiderich questioned if
there was an industry standard? Mr. Griffith stated there is not, although you could
collect enough to cover depreciation. Last year the pipes and reservoirs depreciated
approximately $700,000 with computer and faculties depreciated$170,000.
It was the consensus of the Board to have a target figure of$500,000 for reserves to
cover distribution, capital and rate stabilization with a separate figure for long-term
supply.
Mr. Wegner questioned whether the members wanted to start collecting and holding
funds in a reserve for future water supply project for specific project amounts or set
aside funds annually? At this time we do not know what the project will be, what the
dollar amount would be, or when a project would start up. He continued by stating
that the next project, whatever that might be, will not have a start up component. The
projects we will possibly be looking at will be Portland, the Clackamas or the Joint
IWB Meeting Minutes February 9,2000

Water Commission. Commissioner Buehner stated that it would not be fair to the
ratepayers to not begin putting aside funds for future water source, whatever that
might be. Mr. Wegner stated that a target figure would need to be in the range of
$10 million within the next ten years.
Mr. Prosser stated that between now and the next year, a project needs to be tied
down so we will know where we are going for our long-term supply. Mr. Griffith
stated that if the choice is to have a$44 million project beginning in 2004 that would
require a doubling in rates. Mr. Prosser stated that we need to set some parameters
and let Mr. Griffith work that into a draft scenario. Commissioner Carroll suggested
that we have Mr. Griffith create scenarios working with $500,000, $1 million and
$1.5 million annually. Mr. Griffith displayed a graph that showed what the rate
increase would look like to collect$500,000 cash reserve annually. It was decided
that Mr. Griffith would create the following scenarios:
0 $500,000 for revenues
• $500,000, $1 million and$1.5 million for water supply projects
These scenarios will then be broken down and display average households rate costs.
We will then attempt to look at consumption patterns within each area (King City,
Durham,Tigard, Unincorporated area). Commissioner Hunt also requested that in
addition to calculating the total cost increase he would like to see the percentage of
increase.
Commissioner Scheiderich questioned how much of the supply component could
possibly add to the SDC's charges. Mr. Griffith stated that without a specific project,
it is very difficult to determine. Commissioner Buehner stated that the Planning
Department is currently reviewing plans for a large project (Eagle's View), which
could be used as a model. Mr. Griffith stated that to review SDC methodology with
existing facilities and CIP plan cannot include a water supply project unless the State
law allows.
Mr. Wegner stated that these scenarios will be brought back to the next meeting in
March as well as cost comparisons.
5. Director's Report
The Board requested printed copies of the information that Mr. Griffith displayed at
tonight's meeting. Mr. Wegner stated that he had distributed to the members two
memos, one titled long term water supply update and water related issues.
Mr. Wegner continued by stating that the memo on water supply update would be
incomplete since we were waiting for the EES report on the JWC. A draft is due
today and will be distributed and MSA will add to the report from the termination
IWB Meeting Minutes February 9,2000
Page 5
point at Copper Mountain to the water service area. He continued by briefly outlining
the information that was distributed on the WWSA, Portland Wholesale Contract
Oversight Committee, and the South Fork Water Board/Clackamas River.
Mr. Wegner discussed the second memo that provided additional water related
information on Portland's turbidity monitoring, Oregonian article on Tigard looking
into South Fork, and Oregonian article about Tualatin placing a$5.5 million revenue
bond on the May ballot.
Mr. Wegner stated that the 2000/01 fiscal year budget will be discussed at the next
regular meeting in March. He also stated that the Annual meeting of the IWB as
outlined in the IGA will be at the Water Facility on February 28th at 7:00 p.m. Each
of the separate entities will need to post this meeting since there will be a quorum of
the entities present at the meeting. At this annual meeting we will discuss the water
supply options and Norman Penner has compiled a little history of the water service
area and where it is today which will be distributed, and will also discuss a potential
rate increase. CH2M Hill will furnish the figures and information at the March 8th
meeting.
6. Public comments
Mr. Jack Polans, 16000 SW Queen Victoria Place, King City relayed to the Board an
unfortunate incident that his wife incurred when inquiring about their utility billing
with the Utility Billing Department. According to Mr. Polaris the personnel was
nasty and refused to deal with Ms. Polaris regarding their utility bill. Mr. Polaris also
requested a copy of the audio tape from this meeting and will prepare his questions
for the Board from that tape.
7. Non agenda items
A brief discussion was held regarding the draft newsletter that Commissioner Hunt
has authored. After this discussion it was decided that Kathy would do some editing
to break up the newsletter for easier readability and clarity and will bring it back at
the Annual meeting on the 28th of this month for the Board's comments.
8. Adjournment
The regular meeting of the Intergovernmental Water Board was adjourned at 7:15
p.m. by a motion made by Commissioner Drangsholt and seconded by Commissioner
Buehner. The next regular meeting of the IWB will be held on March 8 at 5:30 p.m.

Attn: Craig Prosser
Finance Director
• City of Tigard
Mr. Prosser,
lam requesting assistance from the City of Tigard Water Board regarding my current.
water bill of$757.67.
On January 7, 2000 I was informed by the Meter Reader from,the City of Tigard Utility
Company there was unusually high water usage occurring at my"residence. The Meter.
Reader asked me to turn off all water inside the house so he could.check the meter more
accurately. .With all.interior water turned off, the meter reader confirmed the meter
continued to show high water usage verifying I had some sortof;leak.He recommended I
call a plumber to find the leak. On January 11,.1 hired 1st Choice;Plumbing to search for
the water leak.problem at my residence. The plumber was unable to identify th.e location
of the,leak and recommended I have a leak detection.service.come to find the exact
location of the,leak. On January 12, Advanced Leak Detection came to the residence and
found the leak between the house and the water meter about four°feet under ground..
Finally on January;13, 1.st Choice Plumbing returned and repaired the leak.
On January 13,I received'a billing statement fromAhe City of Tigard Utility Company in
the amount of$420.20. They included in my statement a Request for Adjustment Due to
a Leak form in recognition of the unusually high bill which I promptly filled out and,
returned. On,February l'6, I received a new billing statement in the amount.of$804.20
and a-notice of credit for $46.53. In reaction to the billing information, I called Utility
Billing.immed iately to request an explanation of the credit. I felt concerned because:of
thelow credit and high,remaining balance for a,water leak problem which was out of my
control. The person I spoke with at the City of Tigard Utility Billing explained.how the
credit was issued and informed me the leak had been occurring since my first billing cycle
in September 1999; She told me the credit had been based on water usage since
September which,is when.I moved into this residence.' She recommended L,write,this
letter'to you to request assistance from,the Water Board'in the payment of this utility bill.
My'landlord, Lois Aungier and I have been in contact throughout this process,and neither
of us were aware of any water problems until.the meter reader informed me,on.January
7th. I am including copies of all service and repair bills as well as my original request for
an adjustment due to a leak form. Please contact me with any questions.
Your consideration in this matter is greatly appreciated.
Thank You,

If you had any doubts before,they should be settled now.
The issue of the new millennium is water.
The city of Tigard has backed away from its rush to the Willamette
River as a new source of drinking water. It will,in the meantime, evaluate
several other options,including a return to the Clackamas River as a water
source or taking water from the Trask River system in western Washington
County.
Meanwhile, citizens in Tualatin through the initiative process will
require a public vote on whether that city should go to the Willamette as a
source for treated drinking water.And in Sherwood,voters will decide in a
March 14 special election whether the city should issue$18 million in
bonds to pay for enhancements to the city's drinking water supply and dis-
tribution systems.Would that plan include water from the Willamette? It
could,but it likely won't if cities like Tigard and Tualatin don't treat
Willamette River water as well.
What's all this talk about water mean to you?
In communities that are unable to provide for a reliable, sufficient
water supply, restrictions on growth could occur. Significant taxpayer
expense to ensure safe water supplies could be another consequence.
In the case of streamside protection, development could be restricted
within 200 feet of each side of a stream.And significant habitat restoration
or enhancement efforts within developoment areas will likely be required.
Property owners in downtown Beaverton and along the Tualatin River
in downtown Tualatin or near Fanno Creek in Tigard are watching the roll-
out of such policies with interest, alarm and suspicion.They fear that their
opportunity to develop or redevelop their land will be halted and economic
activity in Washington County harmed.
They could well be right,unless there is both a measure of science,
economic and community balance and environmental protection provided
for in the discussion and the writing of rules and procedures.There cannot
be one without the others.
Whether the issue is municipal drinking water or streamside protection
for fish and other wildlife,the issue for this decade will be water.Along
the way, as the issues are studied, debated and resolved, moderation and
balance must be imposed for fear of someone or some community drown-
ing in negative consequences.

Regional Water Providers Consortium
Regional Transmission and Storage Strategy
Board Discussion Draft Report
^' February 22, 2000
MONTGOMERY WATSON
EXECUTIVE SUMMARY
Introduction
The Regional Water Provider's Consortium (Consortium) is seeking to develop a
Regional Transmission and Storage Strategy (RTSS). This Strategy is an outgrowth of
the regional cooperation that began with the development of the Regional Water Supply
Plan (RWSP) and continues with the work of the Consortium. The purpose of this
Strategy is to develop short and long-term visions for regional transmission and storage,
and to identify the institutional arrangements that can facilitate these visions.
The Consortium determined at the outset of this process that the Strategy should identify
ways that future planning could complement and. integrate water supply improvements
that are already happening in the region. The RTSS should also provide the information
that water suppliers need in order to make informed decisions about future transmission
and storage projects.
The Strategy was developed in coordination with the Consortium Technical
Subcommittee (CTSC), and the Consortium Technical Committee (CTC). These groups
provided regular input and direction for the development of this project. In addition,
review, comment, and direction on work elements was received from the Consortium
Board. Public and stakeholder input was received in two open houses held over the
course of the project.
Montgomery Watson was selected to prepare the Regional Transmission and Storage
Strategy by the Regional Water Providers Consortium in response to a request for
proposals. A contract authorizing this work was signed and dated June 14, 1999. Major
subconsultants for this work were Murray, Smith & Associates (MSA), Financial
Solutions Consulting Group (FSCG), and Gary Fiske and Associates (GFA). A number
of other consultants with experience in local regional planning acted as advisors and
reviewers of work products on the project.
Projected Water Demands
One of the most critical variables in determining the requirements for water infrastructure
development are the water demands that must be satisfied. The Portland region as a
whole developed a regional forecast of future water demands when it developed the
Regional Water Supply Plan (RWSP) in 1996. Subsequent to the RWSP, a number of
water systems continued to modify and develop their own water demand forecasts. Some
of these forecasts were prepared as part of developing Water Master Plans to fulfill the
requirements of the Oregon Health Division for water system planning. Other forecasts
were developed to better represent the ongoing changes in water consumption and the
impacts of conservation that have been observed since the RWSP forecast was prepared.
Regional Water Providers Consortium page ES-I
Regional Transmission and Storage Strategy Development
Project Report
Executive Summary
-draft 2/18/00
For this project, water demand information was provided by the member agencies of the
Consortium. Because the demand numbers were obtained from a variety of different
sources, they are not consistent with respect to the assumptions that are inherent in the
forecast from each water provider, and comparisons in forecasts between water systems
should be made carefully
The current water demands for peak day and average day consumption, as well as
projected demands to the years 2020 and 2050, are shown in Table ES-1. The source of
the demand information for each water provider is also indicated in Table ES-1. Table
ES-1 shows a total projected year 2020 peak day demand for the region of about 550
MGD. This rises to 660 MGD by the year 2050. The total projected regional average
day demand in the year 2020 is about 260 MGD. This rises to about 315 MGD by the
year 2050.
Existing Supply, Transmission and Storage for the Region
The metropolitan region is currently supplied, or will soon be supplied, by six major
sources of water. Major sources are defined as those with a capacity of 10 mgd or
greater. These major sources are:
• Portland's Bull Run supply
• Portland's Columbia South Shore Well Field
• The Joint Water Commission (JWC) Water Treatment Plant utilizing the
Trask/Tualatin system
• The Clackamas River utilized by four water suppliers
• The Willamette River supply currently under design and construction
• Local groundwater.
Water in Portland's Bull Run watershed is stored in two main reservoirs with a total
storage capacity of about 17 billion gallons. The Bull Run supply is then conveyed by
gravity via three transmission pipelines (Conduits 2, 3 and 4) from the Headworks to a 50
MG reservoir on Powell Butte. Transmission capacity of the three conduits ranges from
205 to 210 mgd depending on hydraulic conditions. Portland's Columbia South Shore
Well Field is located near the Columbia River between the Portland airport and Blue
Lake Park. The firm emergency capacity of the Well Field is considered to be
approximately 90 mgd. In addition to the transmission systems associated with these
sources, the Portland system includes a major transmission pipeline from Powell Butte to
eastern Washington County.
The Joint Water Commission treats water withdrawn from the Tualatin River (including
stored releases from Barney Reservoir and Hagg Lake) at a Water Treatment Plant in
Forest Grove, and pumps it to the 20 MG Fernhill Reservoir.

Clackamas River Water (30 mgd), the South Fork Water Board (20 mgd), the City of
Lake Oswego (16 mgd) and North Clackamas County Water Commission (8.5 mgd) each
have separate intakes and water treatment plants on the lower Clackamas River. Each
facility has its own pumping, treatment, storage and transmission systems for delivery to
its customers.
The Willamette River is currently being developed as a new source by the City of
Wilsonville and the Tualatin Valley Water District. Other communities in southwest
Washington County may also participate in the project. Anticipated initial capacity of the
new water treatment plant is 10-15 mgd to serve Wilsonville, with an intake capacity of
from 70 to 120 mgd. The initial project is scheduled to be completed in April 2002.
Several water purveyors currently rely on groundwater as their primary source of supply.
Some of these are the cities of Milwaukie, Wood Village, Fairview, Wilsonville and
Sherwood and the Damascus Water District. Many other providers also rely on local
groundwater for emergency backup or to meet peaking needs.
The RWSP identified that most of these existing regional sources of supply have the
potential of being expanded in the future should the need arise.
Supply from the Bull Run could be expanded through construction of Bull Run Dam No.
3. A new supply conduit (Conduit 5) could be built to accompany Dam No. 3, or as a
replacement and addition to the existing three Bull Run conduits. The Portland Water
Bureau also completed a Master Plan for the Powell Butte site that would allow the
construction of up to three new 50 MG reservoirs at the same elevation as the existing
Powell Butte Reservoir (530 feet) and a 20 MG reservoir at an elevation of 600 feet.
Expansion of the reliable capacity of the Columbia South Shore wellfield could be
accomplished through drilling additional wells and/or aquifer storage and recovery using
the Bull Run source. Expansion up to 120 mgd is being investigated.
The water treatment plant for the JWC Trask/Tualatin system is designed to be expanded
to a 120 mgd peak day capacity and the planned future phases of the second transmission
pipeline from that source are sized to carry that capacity. The RWSP identified the
Cooper Mountain area as a location for a future large (50 MG) storage reservoir at
approximately the same elevation as the 530 feet Powell Butte reservoirs.
All four water suppliers using the Clackamas River as a source have the potential for
expanding their water treatment, storage and transmission systems. The RWSP showed
potential expansions of up to approximately 140 mgd from this source. Applications for
additional water rights to expand the withdrawals from the Clackamas River further are
currently in process. The RWSP also discussed a large storage reservoir (50 MG) along
Foresythe Road on the south side of the Clackamas River.
The existing water rights of Wilsonville and the Tualatin Valley Water District on the
Willamette River would support an ultimate 120 mgd capacity from this source. To

utilize this water, transmission capacity would have to be built to the north, to the
proposed Cooper Mountain Reservoir, to the City of Tigard's 10 MG reservoir, or to
other reservoir locations within the area served by the source.
In the RWSP, the region was considered to essentially contain three main nodes — East,
West and South. For purposes of this analysis, these primary demand nodes roughly
correspond to Multnomah, Washington and Clackamas counties. The combined year
2050 peak day demands for these three nodes utilizing the demand numbers from Table
ES-1 are shown in Table ES=2. Also shown in Table ES-2 are the major sources in those
nodes and a rough approximation of their current or anticipated development capacities.
As indicated in Table ES-2, each node is in approximate balance between demand and
sources within the node to the year 2050, assuming that these sources are developed and
utilized as planned over time. Currently, much of the demand in the West node is served
not by sources within that node, but by the Portland system.

Every water provider should have the capability of obtaining an emergency source of
water in case its primary source is unavailable for any reason. The capacity of this
emergency source should be able to meet average annual demand. This would provide
water for typical domestic, commercial and industrial use even during the emergency.
Most water providers in the region currently have access to some emergency backup
supply, with some exceptions. Most of these exceptions would be eliminated if the
Willamette River Water Treatment Plant and an interconnection between water treatment
plants in the Clackamas Basin were completed.
Regional Water Providers Consortium page ES-4

Project Report
Executive Summary
-draft 2/18/00
Use of some of these emergency sources is based upon interties between water systems.
The main existing interties that are currently active between water systems in the region
that are not used routinely as water supply connections are:
• CRW—PWB: 4— 8 mgd
• Milwaukie—PWB: 2 mgd(not active)
• Milwaukie—CRW: 2 mgd
• Milwaukie - Oak Lodge WD: 2 mgd (not active)
• Lake Oswego—PWB: 1-3 mgd
• Lake Oswego—West Linn (SFWB)—3-5 mgd
• Beaverton- PWB: 2—4 mgd
• Beaverton—TVWD—4 mgd
• Beaverton—Tigard— 1-2 mgd
• Tigard—Lake Oswego: 4- 8 mgd
• Tigard—TVWD: 2 mgd
Although most providers in the region have access to some emergency source of water,
there are limitations on these emergency connections. In some cases, (such as for those
providers on the Portland system), the capacity of the emergency source may not meet
current annual average demands. For others, such as the suppliers in the Clackamas
Basin, the emergency supply is simply another supplier using the Clackamas River.
Thus, if the Clackamas River is lost as a source for any reason, emergency supplies
would not be available.

An approach to strengthening emergency connections in the region would be to require
that every water provider have access to both a primary source of supply that is one of the
six major regional sources, and to a secondary source of supply that is another of the six
major regional sources of supply. Table ES-3 summarizes how the region currently looks

from this perspective on the general nodal basis. Table ES-3 shows that the emergency
demand for the East Node is slightly greater than the 'existing capacity of the Columbia
South Shore wellfield and both the West Node and South Node require improved
emergency connections.
Evaluation Criteria
There are a number of potential visions for regional transmission and storage. In order to
select among these potential visions, criteria by which the options can be compared are
needed. Several previous regional planning efforts have considered criteria for
evaluating the options for regional water projects. These previous planning efforts were
reviewed as a basis for identifying issues and developing the evaluation criteria for this
project. From these past efforts, a draft list of criteria was developed. The criteria were
reviewed by the Consortium Technical Subcommittee (CTSC) and the Consortium
Technical Committee (CTC). Final draft versions of the criteria were reviewed by the
Consortium Board. The final version of the key issues and evaluation criteria are given
below. It is recognized that some of these goals may be mutually exclusive, and
therefore, transmission and storage options may do better at satisfying some than they do
others, or that compromises that provide only partial benefits may be needed.
Efficiency. Maximize the use of current supplies before developing new ones.
"Weather-driven" reliability. Minimize future daily and seasonal shortages, including
their magnitude, frequency, duration, and number of agencies affected, that result from
existing supplies and infrastructure not being able to serve demands.
Emergency reliability. Minimize future shortages, including their magnitude,
frequency, duration, and the number of agencies affected, that result from unexpected
failure of supplies or facilities due either to catastrophic events or other causes.
Water quality. Meet regulatory drinking water standards for all water delivered to all
providers. Maximize the ability of individual providers to choose the source(s) of
delivered waters. Maximize consistency among providers and over time of delivered
water quality. Minimize adverse water quality impacts within the transmission and
storage system.
Transmission and Storage Cost. Minimize cost to the region of developing
transmission and storage facilities. Maximize the perceived fairness of the manner in
which costs are shared among the region's water providers.
Source Cost. Minimize the cost of source development.
Regional Water Providers Consortium page ES-6
Regional Transmission and Storage Strategy Development
Project Report
Executive Summary
-draft 2/18/00
Transmission and Storage Environmental Impact. Minimize adverse environmental
impacts due to construction and long-term operation of the facilities. Maximize
environmental benefits.
Source Environmental Impact. Minimize adverse environmental impacts of source
development. Maximize the environmental benefits.
Regional operating flexibility. Maximize the ability to use water from various sources
in order to meet demands throughout the region.
Long-term system development. Minimize the foreclosure of long-term supply and
infrastructure options due to near-term actions.
Ability to meet immediate local needs. Minimize limitations on local agencies'
abilities to meet their short-term needs.
Legal/regulatory feasibility. Minimize legal and regulatory hurdles. Facilitate regional
growth goals, standards, and requirements.
Institutional/ inancial feasibility. Minimize the magnitude and difficulty of required
institutional changes. Minimize the difficulty of reaching agreement on regional/local
control issues.
Preliminary Scenarios
Four basic scenarios were developed to represent a broad range of visions for regional
transmission and storage. In addition to the four scenarios, a "base case" representing the
existing situation was included for comparison purposes. Projected water demands to the
year 2050 formed the basis for facility sizing under each scenario. These scenarios are:
Base Case: The Base Case includes not only the existing transmission system, but also
several transmission facilities that various water providers in the region have already
committed to building in the future. While some of these projects may not be constructed
for a long time, they are nevertheless considered as "givens" from the point of view that
planning for additional facilities should consider these facilities as if they were certain to
happen. These projects include currently planned transmission improvements of a new
72-inch diameter line from the Joint Water Commission to the Tualatin Valley Water
District, a new 96-inch diameter Conduit 5 for the City of Portland, a 60/54-inch diameter
Willamette transmission line north from Wilsonville to Tualatin, and a 30-inch
interconnection of between some of the water treatment plants on the Clackamas River.
Scenario 1 - Holistic. Scenario 1 reflects the concepts developed as part of the RWSP.
This concept envisioned major regional water supply sources connected to regional
storage facilities through a transmission system which allowed each local provider to
Regional Water Providers Consorth ni page ES-7
Regional Transmission and Storage Strategy Development
Project Report
Executive Summary
-draft 2/18/00
ultimately use one or more of all of the supply sources to meet peak season and peak day
demands. The model for this approach is the electrical power grid system, whereby a
transmission network is established that allows various source generation facilities to be
utilized by customers. It allows any potential excess capacity from any source within
the region to be brought to where demand is needed.
Major elements include a 96-inch diameter transmission main from Powell Butte to the
Clackamas Basin area, a 60-inch diameter transmission main from Clackamas to Tualatin
and transmission pipelines to carry 120 mgd of water north from a Willamette River
water treatment plant in Wilsonville. This scenario also assumes that new regional
storage reservoirs would be built in Washington and Clackamas Counties in order to
smooth operation of the regional system. Estimated cost of this scenario is approximately
$350 million.
Scenario 2 - Emergency Interconnections. This scenario reflects a primary and
emergency source approach where each local provider develops or selects its own
primary water supply source from one of the regions six major sources. Each provider
also independently or jointly develops emergency average day demand backup supplies
from a second, separate source that is another of the region's six major sources. The
Powell Butte to Clackamas connection is built at a smaller diameter, 54-inch, than in
Scenario 1, the Willamette transmission pipeline is only sized for 60 mgd, and the
Clackamas to Tualatin pipeline is not constructed under this scenario. Estimated cost of
this scenario is approximately $100 million.
Scenario 3 - Zonal. Scenario 3 reflects the development and use of regional storage and
transmission facilities to serve zonal supply sources developed to their maximum
capacity. The regional transmission and storage facilities are sized to serve two specific
geographic areas, east and west, from these sources. The east zone is served from the
Portland and Clackamas River supplies and the west zone is served from the Joint Water
Commission and Willamette River supplies. The dividing line between the east and west
zones is the west slope of the West Hills that run south from Portland through Lake
Oswego and West Linn. It allows for each of the major sources in each zone to be
transmitted as needed within the zone and provides a small intertie between the zones.
Estimated cost of this scenario is approximately$250 million.
Scenario 4 - Subregional Interconnected. This scenario reflects the ultimate
development of existing sources and supplies to serve expanding water demand needs.
Included under this scenario is the further interconnection of City of Portland,
Trask/Tualatin and Clackamas Rivers supplies as well as an east to west connection of
existing Clackamas River supplies. It assumes that the Willamette source does not
expand service beyond Wilsonville and perhaps Sherwood. Estimated cost of this
scenario is approximately $200 million.

Institutional and Financial Concepts
Development of a regional transmission and storage strategy may require the creation or
expansion of governance institutions, and can entail new financial commitments by the
participating water providers. Selection of an appropriate institutional model and a sound
financial structure are linked to the selection of a desired transmission/storage scenario.
Some institutional and financial approaches are best suited to specific scenarios; others
are relatively flexible and universally applicable to any favored scenario.
Several different institutional models were reviewed for application to the regional
transmission and storage scenarios that were considered in this project. The use of
Intergovernmental Agreements was found to offer the greatest flexibility and opportunity
for regional consensus building. This study also examined several financing instruments
including volume charges, capacity charges, membership dues, buy-ins/buy-outs,
regional SDCs, local SDCs, and capacity leasing. All of these options have the capability
of being utilized in developing regional transmission and storage projects. The exact
ones that are utilized should be selected as part of the Intergovernmental Agreements that
are formed.
Evaluation Of Scenarios Against The Project Criteria
Each of the preliminary regional transmission and storage scenarios, including the Base
Case, was considered against each of the evaluation criteria identified above. Rating of
the scenarios against the criteria was qualitative, that is, numerical ratings were not
assigned. Scenario ratings were reviewed by the CTSC, the CTC and the Consortium
Board. Some observations can be made about each scenario based on the evaluation.
Scenario 1 - Holistic. This scenario consistently ranks highest for the criteria that relate
to the benefits that the regional transmission system generates. These benefits are factors
such as reliability, flexibility, efficiency,' and the ability to take advantage of
environmental benefits. At the same time, this scenario consistently ranks the lowest for
criteria such as cost, legal and regulatory feasibility, and institutional and financial
feasibility - all indications of how difficult it will be to actually build this vision of
regional transmission. It also ranks lower on the ratings of implications for source
development, because it creates an unconstrained market for source that could result in
overbuilding of source facilities.
Scenario 2 - Emergency Backup. This scenario provides moderate benefits in terms of
improving regional reliability, but does not allow much benefit in terms of environmental
enhancement or efficiency. However, it has the lowest cost of all the scenarios (except
the Base Case) and would be the easiest to implement.
Scenario 3 - Zonal. This scenario provides the same types of benefits as the Holistic
scenario in terms of reliability, environmental impact, efficiency and flexibility, but not
Regional Water Providers Consortium page ES-9
Regional Transmission and Storage Strategy Development
Project Report
Executive Summary
-draft 2/18/00
quite to the same level as the Holistic scenario (perhaps 80% of the benefits obtained in
Scenario 1 are obtained in Scenario 3). However, the cost of Scenario 3 is only two-
thirds the amount of Scenario 1 and it will be considerably easier to implement. Also, it
is less likely to lead to overbuilding of sources, because supply and demands are more
matched at the subregional level.
Scenario 4 - Interconnected Subregional. This scenario has a cost that is a bit lower
than Scenario 3 due to exclusion of storage reservoirs, but does not attain the same level
of benefits for the region as Scenario 3. The main reason is that this scenario does not
include any substantial development of the Willamette River as a supply. Because the
Willamette is the surface source most resistant to drought of those involved, and because
it is the least susceptible to impacts from the Endangered Species Act, having it as part of
the regional mix adds flexibility and reliability that cannot be achieved without it.
Scenario 4 also will be more difficult to implement than Scenario 3, although not as
difficult as Scenario 1.
Base Case. The Base Case does not achieve enhancements of reliability, efficiency,
flexibility, or environmental benefit. Its cost is of course the lowest, and since it is the
"do nothing" alternative, it is the easiest to achieve.
Public Information and Involvement and Consortium Board Input
Public information in the RTSS planning process has been provided directly via public
information brochures, and indirectly via newspaper stories. Staff for the Consortium
prepared an information brochure concerning the project and mailed it to a 3,800-name
project mailing list. This mailing list included individuals that expressed interest in past
regional water planning activities as well as environmental groups, large water users,
regulatory agencies, water suppliers and others in the region. Consortium staff also
provided a briefing on the project to the City of Portland's Water Quality Advisory
Committee. A number of articles concerning the project have also appeared in The
Oregonian newspaper.
The first Public Workshop on the project was held on November 9, 1999 at the Oregon
Institute of Technology Conference Center in Milwaukie, Oregon. Approximately 20
people attended the Workshop. The Workshop covered the project evaluation criteria,
scenarios and financial and institutional options. Comments received at the workshop
indicated that participants were in agreement with the evaluation criteria that were being
utilized. They also felt that the scenarios that were being proposed represented an
adequately broad range of options for discussion.
The Consortium Board has provided input and direction for the development of the draft
RTSS. At the Board's September 1999 meeting, the evaluation criteria and scenarios
were discussed. Modifications to the evaluation criteria were made to address Board
comments. The Board commented that the range of scenarios being presented
represented a good range of options for further evaluation.
Regional Water Providers Consortium page ES-10
Regional Transmission and Storage Strategy Development
Project Report
Executive Summary
-draft 2/18/00
The December 1999 meeting of the Consortium Board considered the draft evaluation of
the scenarios. Board members identified which of the policies represented by the
evaluation criteria for the project were rated as "most important" for the RTSS. The
criteria that Board members rated the criteria as most important were:
• Emergency reliability
• Water Quality
• Cost
Discussion at the meeting indicated that the Board members felt that the vision for the
RTSS should not be constrained by issues of legal, regulatory and institution feasibility,
short-term needs, or environmental issues. These concerns would be represented in the
higher projected costs for some scenarios or could presumably overcome with the
appropriate level of effort. This was why those criteria did not rate high.
In the discussion of the scenario evaluations, Board members expressed three major
points. These were:
• Improved emergency interconnections (such as the Emergency Scenario 2) between
and among water systems in the region are vital. These interconnections would
improve regional reliability and improve access to emergency supplies of water when
there were problems with an individual source or system.
• The costs of a transmission system that allows very large quantities of water to be
moved throughout the region (such as the Holistic Scenario 1) does not appear to
justify whatever added benefits this approach would achieve, compared to less
ambitious regional interconnections.
• The long-term network should be consistent with the decisions that communities
make that are now looking for new sources of supply and should be phased and built
from the nearer-term improvements. The uncertainty concerning which sources in the
region will ultimately be utilized has a serious impact on any commitment to a large
transmission system. The most appropriate transmission network might look
different depending on the source that Tigard, Sherwood and others in southern
Washington County that are looking for water, chose as their primary supply during
the next few years. If the source for these communities becomes the Willamette
River, then perhaps the Zonal Scenario (Scenario 3) would be most appropriate. But,
if the Portland system or the Clackamas River becomes the source, Scenario 4 may be
more appropriate. The RTSS should be phased in a manner that allows nearer-term
improvements to be made to improve emergency interconnections, but then allows
the longer-term network to be consistent with source decisions as they are made.
Regional Water Providers Consorthan page ES-11
Regional Transmission and Storage Strategy Development
Project Report
Executive Summary
-draft 2/18/00
These three key points become the primary drivers for the recommended Regional
Transmission and Storage Strategy presented below.
REGIONAL TRANSMISSION AND STORAGE STRATEGY
Based on all the above information, the recommended Regional Transmission and
Storage Strategy is:
Build interconnections between and among individual water systems within the region
to increase the reliability of supply to individual communities and to the region as a
whole.
In the long-term, develop either a Zonal or Interconnected Subregional transmission
and storage system, depending on the source(s)that the communities in southern
Washington County that currently need water, develop for their primary supply.
Develop these projects through intergovernmental agreements (IGA's)among those
benefiting from and participating in the individual projects.
Specific elements of the Strategy should include:
• Each community in the region should have access to both a primary supply and
an adequate emergency source of water.
• The primary supply should be one of the six major sources in the region (Bull
Run River, Columbia South Shore Wellfield, Clackamas River, Trask/Tualatin
River, Willamette River, local groundwater).
• The emergency supply should be sized to meet at least the annual average
demand of the community and should be a separate source from the primary
supply. Preferably, the emergency source would be one of the six major sources
in the region that is not the community's primary supply.
• The sizing of interconnections between water systems should consider future
potential peak season and peak day supply needs as well as emergency needs.
Sizing of each specific project should be reviewed and modified at the time the
project is actually designed and constructed.
• If a new east-west transmission connection is made within the region, it should
be via a route that allows connection of the supplies from the Clackamas basin to
be to both the Portland system and Washington County.
Regional Water Providers Consortium page ES-12
Regional Transmission and Storage Strategy Development
Project Report
Executive Summary
-draft 2/18/00
• While the primary elevation for the transmission connections should be set
based on the existing major storage reservoirs in the region (Portland's Powell
Butte Reservoir at around 530' elevation and JWC's Fernwood Reservoir at
around 520' elevation), not all of the transmission system flow need go to this
elevation. Much of the service territory in the region can be served at elevations
in the 450' to 490' range. Pumping costs from the river system water treatment
plants can be reduced substantially if a portion of the flow goes to the lower
elevations. Similarly, there are portions of the region that require higher
elevations for service. As specific storage and transmission projects are designed
and constructed, these elevation issues should be considered. Pipeline design,
however, should be based upon the pressures of the 530' elevation so that there
are no limitations in the utility of the transmission pipelines.
• The timing for construction of each project in the Strategy should be determined
through negotiations among the project participants that are interested in
building the project.
The benefits of putting this regional transmission strategy into place include:
• Improved protection against loss of any water source for any reason.
• Improved ability to bring available water supplies to communities that may need
water.
• Improved flexibility to respond to environment concerns in source waters.
• Ability to utilize lower cost water sources in the winter when water is plentiful and to
close higher cost sources during those periods.
• Improved ability to utilize surface sources as part of aquifer storage and recover
projects.
The institutional model that is recommended for implementing the elements of the short-
term strategy is Intergovernmental Agreements (IGA's) organized under ORS 190. This
institutional arrangement offers the greatest array of options for developing detailed
system guidelines. It allows relatively easy "evolution" to accommodate future changes
in institutional scope or mission. It retains local representation and control while entering
into the regional strategy. For each of the projects under RTSS, IGA's could be
developed between the project participants to identify cost allocations, operating
responsibilities and other obligations and requirements.
There are several projects that are currently already in the adopted Capital Improvement
Programs (CIP's) of various water providers in the region. These projects should be

• The second transmission line from the Joint Water Commission water treatment plant
in Forest Grove that would connect to the Tualatin Valley Water District (TVWD)
and the transmission improvements in the TVWD system to bring this water to its
storage reservoir.
• The transmission line from the City of Wilsonville's new water treatment plant using
the Willamette River as a source, north to its termination point. This termination
point is currently assumed to be within the City of Wilsonville, but may extend
further north depending on upcoming decisions of other communities.
• An interconnection between the water treatment plants using the Clackamas River as
a source.
• The downstream portion of Bull Run Conduit 5.
• A second reservoir on Powell Butte.
Several other major projects are recommended for further exploration consistent with this
strategy and are also shown in Figure ES-1 and Table ES-4. These are:
• An intertie between the Joint Water Commission and the Portland system.
• An intertie between the Portland system and water sources in the Clackamas basin.
• An intertie between the terminus of the Willamette transmission pipeline and the Joint
Water Commission pipeline.
Also shown in Table ES-4 are several possible other projects that depend on future
decisions about the regional water supply network.
The routes shown in Figure ES-1 are representative of the general corridor that the
transmission pipeline would take. As discussed in Section 5, there are multiple
alternative routings for each pipeline. The specific routing for each pipeline should be
determined through more detailed study of options and negotiations among those water
providers participating in actual project construction.
If the communities in southern Washington County that are currently looking for a long-
term source of water(Tigard and Sherwood) decide to use either the Clackamas basin
supplies or the Portland system, then a pipeline from the Clackamas basin to those
communities should be constructed. If those communities decide to use the Willamette
River as their source of supply, then the Willamette transmission pipeline should be sized
larger and the connection to the JWC system completed earlier. If those communities
decide to use the JWC source as their supply, then the JWC interties to the Portland and
Willamette systems should be sized larger and these connections completed earlier.

Executive Summary
-draft 2/18/00
Other local connections or improvements in connections between individual water
providers should also be undertaken as part of the Regional Transmission and Storage
Strategy. Examples of these may include:
• Capacity increases of the existing intertie between Clackamas River Water and the
Portland system,
• Reactivation of an inactive connection between the Portland system and the Oak
Lodge Water District,
• Improved connections between Portland and Lake Oswego, and Portland and
Milwaukie, and
• A connection between Fairview and Wood Village.
While these connections may not be of regional significance by themselves, the
cumulative effect of the sum total of many of these improvements could be of regional
significance.

lanes to three, retaining walls, sidewalks, storm drainage
improvements and vertical and horizontal realignment. The County
postponed this project during 1997 due to Measure 47.
$60,000 Replace 800 feet of 6-inch cast iron water main with 6-inch ductile
pipe on SW Lincoln Street from SW Greenburg Road to SW 91s'
Avenue. This is an on-going program of replacing old cast iron
water mains with ductile iron pipe as part of the City's street
improvement program.
$401,000 Construction of pressure reducing stations within the Bull Mountain
system. The pressure reducing stations are constructed as
needed, when new subdivisions come on-line. On Bull Mountain
properties below an elevation of 580 feet are serviced from the
713-foot service zone. At an elevation of 430 feet, the water
pressure becomes excessive and the operating (working) pressure
must be reduced. Depending upon timing, we have identified two
proposed subdivisions (Autumn Hill and Quail Hollow West) that
would require pressure-reducing facilities.

RE: Proposed Portland Wholesale Water Rate
DATE: March 7, 2000
At the February 9, 2000, of the Water Managers Advisory Board, the projected FY
2000-01 wholesale water rates were discussed in great detail. The bottom line is that
the overall rate to wholesale purchasers will increase by 10%, in our case the rate is
reduced by 29%. '
With the new method for purchasing water from Portland during the summer season,
the ability to say within 10% of hourly and daily purchases from Portland, all wholesalers
achieved a peaking factor of 1.0. Meaning that none of the wholesalers "peaked" on the
Portland system. With none of the wholesalers "peaking" last summer, the costs are
evenly distributed to others in each of the service areas. In addition to spreading the
costs evenly, Portland is passing along across the board increases.
The contributing factors to the cost increases, outside of the peaking factors being 1.0,
are:
Y The five year average cost of government debt, per Wall Street Journal as outlined
in the current 25-year agreements, increased from 4.8% to 6.25% which increased
wholesale rates 3%.
y Operating costs make up 5% of the rate increase. In Portland's FY 2000-01
proposed Budget, new and enhanced projects total $2.2 million. These program
enhancements include work force planning and development, Endangered Species
Act response, response to regulatory compliance, CIP and engineering support staff
increases, and GIS maintenance.
Demand reduction to recognize TVWD increased reliance on Joint Water
Commission water, which increases rates approximately 2%.
Due to the way the rates are calculated, according to the current 25-year contract, rate
of return fluctuations greatly influences rates. The most vocal of the wholesalers was
Gresham. Gresham's cost to purchase Portland water will increase from $0.475 to
$0.61 per ccf. This represents a 28% increase, and they were wondering how they can
.pass such a large increase to their customers when Portland is only proposing a 6%
increase to their own retail customers. Gresham is wanting to find a new way to
calculate the rate outside the current agreement. Portland stated that they used the
•4
Y
methodology contained in the 25-year agreements and we are stuck with it until the
contracts expire. Portland also stated that this is one of the reasons to participate in the
new contract discussions.
Tualatin Valley Water District will see a 20% increase in their wholesale rate. This is
bad news to Tigard since our cost to purchase Tualatin Valley Water at Baylor Street is
based on TVWD's wholesale cost plus cost allocations of the Washington County
Supply Line, their O&M and JWC costs. We are estimating that TVWD's cost of water
to Tigard will be over $0.90 per ccf in FY 2000-01.
So what does this all mean? As you can see in the attached rate table from Portland,
there is no $0.50 per ccf at Powell Butte. In fact, Service Area 1, which is serviced via
the conduits and should have the lowest rates, is at $0.61 per ccf. How Portland could
ever hope to have $0.50 per ccf water at Powell Butte, as stated in their December
1998 proposal to provide water to Southeast Washington County, was black magic at
best.

FROM: Michael Rosenberger
Administrator I �'
SUBJECT: Projected FY 2000-01 Rates
Please find attached preliminary rate information for FY 2000-01. These rates assume that all
districts maintained the 10% peak flow pattern last summer. Once the peaking factor analysis is
complete districts with peaking factors will have higher rates and districts that maintained the
smooth pattern (did not peak)will have slightly lower rates. There are also possible rate
changes due to budget adjustments befiveen now and the rate ordinance in May. The
"Requested Budget" document will be available at the February 8 meeting and mailed to districts
not at the meeting.
Volume rates by wholesale customer are listed on the attached Table 1. These rates are based
on the Water Bureau's preliminary FY 2000-01 budget and calculated according to the 25-year
contract cost of service methodology. The table shows a comparison between the "Projected
Rates 2000-01" and the current"Ordinance Rates". All districts in a service area have the same
projected rate because we are assuming all districts have the same peaking factor.
A breakdown of O&M, Depreciation, and Rate of Return charges is summarized by Service Area
on Table 2 - "2000-01 Cost-of-Service Allocation." The Service Area unit costs shown on
Table 2 are the service area total costs divided by the total consumption in the service area.
Table 3 shows comparisons between FY 99-00 and FY 00-01 for both overall wholesale costs
and costs per CCF.
Overall average rate increase to wholesale users is about 10%. (Inside-City increase is
projected at about 6%.)
. 4
Preliminary FY 2000-01 Rates
Water Managers Advisory Board
February 1, 2000
The fac'o-Is contributing to the 10% increase are:
The five-year average cost of government debt (per Wall Street Journal).increased from
4.8 to 6.25, which increased wholesale rates 3%.
Operating costs add about 5% to the rate increase (inflation = 3% and enhancements
2%). In FY 2000-01 budget new or enhanced projects total about$2.2 million. These
program enhancements include—workforce planning and development, Endangered
Species Act, regulatory compliance, CIP and engineering support staff, and Gla
maintenance.
Demand reduction to recognize TVWD increased reliance on Joint Water Commission
increases rates about 2%.
As you can see on Table 1 most customers' rates are increasing more than 10% because the
rate calculation assumes all districts operated within the peak use pattern. Costs are shifted
away from districts with higher peaking factors last rate year(i.e. Tigard and Rockwood) and are
shared by all districts. Anne Conway explained this potential cost/rate shift last June and
October. There will be further rate adjustments to reflect the final peaking analysis.
A discussion of rates is on the agenda of the February 8 WMAB meeting. If you have questions
before the meeting please call Anne Conway at 823-7468.
These proposed rates will be reviewed by the Commissioner-in-Charge and may change because
of City Council action on the Bureau's budget. As provided for in the 25-year Agreement, purchaser
will be sent a copy of the rate ordinance and notice of the City Council hearing.

Department Results Statement
Tigard has a safe and reliable water system that meets or exceeds all EPA and Oregon Health
Division standards for water quality. All the while efficient water service is provided under
normal, peak, and emergency situations.
Budget Highlights
■ The budget request is down 13.7%, primarily die to the reduction,in the cost of water from
the Portland system following the reduction in the peal-pricing factor.
■ The division is transferring one position to the Finance department and adding one new
position for no net increase in FTE.
• Overall, materials & services is down due to decrease in the cost of water. Several line
items are increasing, however:
✓ Water sampling costs are up due to the return of Well #3 to service
✓ Repair and maintenance is up due to the increasing age of the system
✓ Change in the definition of capital outlay
✓ Budgeting for repair of hand-held radios
✓ The division is proposing several program enhancements to improve water conservation
efforts in the City of Tigard.
■ The requested budget is well within the 2000 Financial Plan projection.
Issues
.1. Water Rates and Operating Costs
The 2000 Financial Plan projected a serious decline in the Water Fund fund balance. The
department is currently examining possible rate increases, which have not been raised since
1993. It now appears that rate increases in the range of 12% per year will be required for
several years just to maintain current operations. In addition, the City should start building
reserves for the future cost of a new source of supply. Required rate increases could therefore
be substantial.
Given the financial outlook, operating costs should be closely examined. While overall costs are
projected to be down in FY 2000-01 due to the passing of the Portland peak pricing penalty, the
department has requested program enhancements to improve water conservation efforts.
Recommendation: Rates need to be increased substantially. The department is carefully
documenting the need for this increase and is working with Tigard's partners to ensure that they
understand the need for the increase. These efforts should continue.
Requested program enhancements to improve water conservation should be funded.
Conserving water reduces future demand and could help to give the City more time to develop
additional sources of water.
