BACKGROUND
The Cities of Lake Oswego and Tigard (the Cities) have initiated a comprehensive study
to develop and evaluate options for the possible formation of a joint water supply system
to serve both cities. In May 2006, Lake Oswego entered into a consulting services
agreement with Carollo Engineers, P.C. (Carollo) to complete this project.
Since that time, many of the initial project goals have been accomplished including
identifying projected water supply demands, development of conceptual alternatives for
water supply improvements, identification of regulatory constraints, development of a
strategic communications plan, and evaluation of governance options. Based on the
work completed to date, the Cities have identified additional services and modifications
to the original scope of work to better respond to the issues, concerns and opportunities
that have been identified.
Details of the proposed amended scope of each task are presented in the following
section. The budget and schedule for these activities are attached.
TASK 1 — EVALUATE WATER SUPPLY SYSTEMS
The following additional work has been requested as part of this task:
A1.1.1. Modifications to Lake Oswego Population and Demand Forecasts
Lake Oswego has requested additional modifications to the population and demand
forecasts developed by Carollo to achieve improved consistency between the Joint
Water Supply System Analysis and Lake Oswego's draft Water Management and
Conservation Plan (WMCP). This task includes additional revisions to initial population
and demand forecasts, development of a summary of proposed forecasting
methodologies, coordination with the draft WMCP, meeting with the City and the City's
WMCP consultant, and revisions to Technical Memorandum 1 based on additional
revisions to the updated methodology.

A1.1.2. Significance of Conservation on Supply Improvements
The City's elected officials have expressed interest in making water conservation a key
element of future supply planning and to build upon the conservation programs each city
has developed. This task includes preparing a technical memorandum (TM) describing
the relative significance of the three potential conservation strategies on the capacity,
cost and implementation schedule of supply requirements, supply scenarios, and the
associated capital improvements for the proposed water supply scenarios. A draft TM
will be prepared for review by the Cities and will be finalized based on the Cities' review
comments. Findings of the final TM will be incorporated into the project report.
It is assumed the Cities will identify potential conservation measures and assumed
conservation targets for each conservation strategy.
TASK 2— EVALUATE WATER SUPPLY FACILITY ALTERNATIVES
The following additional work has been requested as part of this task:
A1.2.1. Evaluation of Alternative Intake via South Fork Water Board
Prepare a brief(one-page) memorandum describing the feasibility and costs of
upgrading the existing South Fork Water Board (SFWB) intake and constructing a new
transmission line to convey the water to the existing Lake Oswego intake. These
improvements would be sized to supplement the capacity of the existing Lake Oswego
intake, to provide a total combined intake capacity equal to Lake Oswego's existing
senior and junior water rights on the Clackamas River. It is assumed that based on this
limited analysis, this alternative will not be considered further in the remaining supply
planning work.
A1.2.2. Evaluation of Interim Supplies to Lake Oswego
This task consists of evaluating two alternatives for interim supply to Lake Oswego to
allow deferring of near-term supply improvements that would otherwise be necessary to
serve the Lake Oswego. The first alternative consists of supply from Tigard using a
connection to the existing Washington County Supply Line (WCSL)from Portland. The

second alternative consists of supply from the South Fork Water Board (SFWB)via an
interne with the City of West Linn. The evaluation of these two alternatives will include
analysis of this alternative supply concept, identification of capital cost and capacity for
two options (Option 1: use of existing pipeline capacity, and Option 2: development of a
new transmission capacity). Capital and O&M costs for associated upgrades will be
identified, and implications for timing of future supply improvements to implement the 24,
32 and 38 mgd water supply scenarios will be evaluated. A matrix will be prepared
presenting a comparison of the alternatives based on various evaluation criteria (such as
capacity, reliability, resource impacts, governance requirements, capital cost, operating
cost, and consistency with long-term supply requirements), The evaluation will be
summarized in a draft and final technical memorandum, with resulting finding
incorporated into the project report.
It is assumed the City of Tigard will provide a recently-completed capacity analysis of the
WCSL. It is further assumed that the City of West Linn and SFWB will assist in
identifying the capacity of the existing intertie between West Linn and Lake Oswego,
system improvements that may be required to increase intertie capacity, and aid in
identifying costs for water purchases.
TASK 3— EVALUATE REGULATORY, PERMITTING, AND WATER RIGHTS
The following additional work has been requested as part of this task:
A1.3.1. Water Rights Overview and Recap
Prepare additional information summarizing existing water rights on the Clackamas
River. This will include: 1) a summary of existing Oregon water law, including a synopsis
of the processes and criteria for establishing and enforcing water right priorities, 2) a
summary of the location, quantity and priority of existing water rights on the Clackamas
River, 3) the existing and projected future water demands of water right holders on the
Clackamas River, 4) maps identifying the location, capacity, current and future demands,
and priorities of existing water rights on the Clackamas River, and 5) a review and
summary of the conclusions of the existing Portland State University (PSU) hydraulic

A1.6.1. Development of Matrix of Governance Issues and Alternatives
To further refine and clarify the governance issues and alternatives for the Cities, a
matrix of the options will be developed. This matrix will identify topics and associated
options for governance, asset ownership, system management, voting rights, system
expansion, buy-out and terms of withdrawal, dispute resolution, capital buy-in, and
addition of future partners. For each option, relative advantages and limitations will be
identified. This task also includes one additional meeting with the City Attorneys from
Lake Oswego and Tigard to review the matrix and identify the preferred alternatives.
TASK 7—CONDUCT FINANCIAL EVALUATION
The following additional work has been requested as part of this task:
A1.7.1. Update and Integration of Tigard Water Supply Options
The original project scope of work related to a financial and economic analysis focused
on a cost comparison of various water supply options. To further support evaluation and
decision-making, the City of Tigard wishes to compare these findings to the results of a
separate analysis addressing other regional supply options. This scope of work provides
task elements to update that separate analysis by applying a consistent set of
assumptions, and to incorporate and document those findings in project documentation.
The work conducted for a regional consortium of water service providers benchmarked
several supply scenarios for Tigard. This study has now revised demand forecasts and
created additional alternate scenarios requiring multiple sources to meet Tigard's
projected needs. This task will update analyses of regional supply costs as alternatives
to, and supplements to, the Lake Oswego supply. Included in this effort are the following
tasks:
• Update existing supply cost analyses based on a revised Tigard water demand
forecast. Coordinate with the City of Tigard to validate revisions to assumptions.
• Develop additional supply cost analyses addressing demands in excess of
supply available from Lake Oswego.

Page 8
• Develop additional summary materials to address this broader perspective on
supply costs for Tigard.
• Participate in one project review session specifically related to Tigard's broader
supply cost issues.
A1.7.2. Develop Rate Impact Forecasts
The Cities of Lake Oswego and Tigard wish to evaluate potential rate impacts related to
the proposed water supply scenarios. This scope of work provides task elements to
develop updated rate forecasts by incorporating supply costs into a water utility rate
forecast model. In each case, FCS Group has previously developed such a forecast
model, which will be updated and used as a platform for the rate analysis.
In order to reasonably forecast rates, related water System Development Charges
(SDCs) also need to be considered. Since this supply evaluation does not consider all
system water investments and improvements, an "incremental" analysis is proposed.
Under this scope of work, supply system capital costs for each scenario will be used to
develop unit costs per gallon of demand. It will be assumed that SDC revenues will be
consistent with that unit cost and annual demand growth. These revenues will be
considered an offset against capital costs, including related debt service. The net
remaining costs will be considered to be supported by rates, thus leading to a rate
impact determination. It should be noted that this analysis will not result in a proposed
revision to either City's water SDC, a work product that is more extensive in its content
and one that would require further and more detailed analytical and process elements
than proposed here.
This supplemental scope includes the following subtasks:
A1.7.2.1. — Develop Lake Oswego Rate Impact Forecast
This task will develop a current version of the City of Lake Oswego's water revenue
requirements model based on current levels of revenues and expenses. The
incremental capital and operating costs of each supply scenario will be incorporated into

Page 9
the forecast to determine rate impacts. Four supply scenarios will be developed in this
fashion. The scenarios include alternatives scenario 2 (stand alone), 3 (senior right), 4
(senior and junior right), and new scenario 5 (senior and junior right with interim Tigard
supply of Portland water to Lake Oswego).
The City of Lake Oswego will provide necessary budget data, non-supply capital
improvement plans, and operations and maintenance (O&M) cost breakdowns as
requested to support the development of this analysis, based on a data request.
• Update the City's water rate forecast(revenue requirement) model with current
budget and system planning information, including the Capital Improvement Plan
(CIP). The operating and maintenance budget will be structured to segregate
supply and treatment costs from other expenses, in order to introduce differential
costs for each supply scenario.
• Develop a unit capital cost to project an estimated SDC revenue stream
attributable to each of four supply scenarios.
• Develop a water rate forecast for each of the four supply scenarios (2-5). The
forecast will portray total annual revenue requirements, projected annual
percentage rate increases and total revenue requirements. Based on preliminary
findings, rate smoothing features will be considered and incorporated as
appropriate to mitigate major rate impacts.
• Document the rate forecast findings in the form of a technical memorandum, and
develop appropriate summary materials to present comparative findings.
A1.7.2.2. — Develop Tigard Rate Impact Forecast
This task will apply a current version of the City of Tigard's water revenue requirements
model based on current levels of revenues and expenses. The incremental capital and
operating costs of each supply scenario will be incorporated into the forecast to
determine rate impacts. Four supply scenarios will be developed in this fashion. The
scenarios include alternatives scenario 2 (stand alone), 3 (senior right), 4 (senior and
junior right), and new scenario 5 (senior and junior right with interim Tigard supply of
Portland water to Lake Oswego).

The City of Tigard will provide necessary budget data, non-supply capital improvement
plans, and O&M cost breakdowns as requested to support the development of this
analysis.
• Update the City's water rate forecast(revenue requirement) model as needed
with current budget and system planning information, including the CIP. As
needed, the operating and maintenance budget will be refined to fully segregate
supply and treatment costs from other expenses, in order to introduce differential
costs for each supply scenario.
• Develop a unit capital cost to project an estimated SDC revenue stream
attributable to each of four supply scenarios.
• Develop a water rate forecast for each of the four supply scenarios (2-5). The
forecast will portray total annual revenue requirements, projected annual
percentage rate increases and total revenue requirements. Based on preliminary
findings, rate smoothing features will be considered and incorporated as
appropriate to mitigate major rate impacts.
• Document the rate forecast findings in the form of a technical memorandum and
develop appropriate summary materials to present comparative findings.
TASK 8— Prepare Final Report
The following additional work has been requested as part of this task:
A1.8.1. Expand Scope of Final Report
The amended scope tasks, described above, will require a significant modification to the
development of the Final Report. The additional white papers, technical memorandums,
and meeting summaries describing the regulations, water rights, strategic outreach,
financial evaluations, and additional Council meetings will be summarized and included
in the Final Report of this Joint Water Supply System Analysis. A decision matrix will be
generated to reflect a subjective evaluation of supply options against the values and
principles and public input identified as part of Task 4.
