ISSUE
Review proposed utility rates in advance of eventual adoption of Public Works Fee Schedule
Resolution for 2023 and 2024.
BACKGROUND
The City's Public Works Department manages three utility funds — Water, Sewer, and Surface Water.
The Water and Sewer Utilities serve approximately 60% of the property owners in the City, while the
Surface Water Utility serves all properties within City limits. Utility rates provide the bulk of the revenue
that supports the operations of the water, sewer, and surface water operations in the City of Tukwila.
These rates are reviewed biennially as a part of the City's budget and Capital Improvement process.
The City's Budget, Capital Improvement Program and Comprehensive Plan all reference or include the
policies that govern rate development. Here are a few examples of the City's policies, as taken from the
Capital Facilities Element (Chapter 14) of the Comprehensive Plan:
• Utility rates and charges shall be structured to ensure adequate infrastructure development, in
addition to compliance with operation, maintenance, and federal and State requirements
• Rate increases shall be small, applied frequently, and staggered to avoid an overly burdensome
increase and undue impact in any given year
• Each enterprise fund shall be reviewed at least biennially, and shall have a rate structure
adequate to meet its operations and maintenance and long-term capital requirements
• Rate increases of external agencies (i.e., King County secondary wastewater treatment fees)
shall be passed through to the users of the utility
Annual rate increases allow the City to keep pace with inflation and fixed cost increases, and to
implement the City's long-term strategic goals for maintenance, improvement, and replacement of
capital infrastructure. Without regularly occurring and sufficient rate increases, the City's ability to
address infrastructure needs would be compromised. In addition, the policies reinforce the importance
of maintaining adequate fund reserve levels.
The City has adopted Comprehensive Plans for Water, Sewer and Surface Water that analyze each
fund for revenue requirements and prioritize capital improvement projects. The City is currently
finalizing the Water and Sewer Comprehensive Plans and Surface Water is scheduled to conclude in
2023. Council adopts the comprehensive plans approximately every ten years and those adopted plans
inform rate studies. Rate recommendations are informed not only through identifying needed capital
projects but by examining trends in charges from suppliers, consumption patterns, and regulatory and
operating needs. Recommended rates are the product of a complex set of intertwined inputs, some of
which are fixed and outside of the City's control. Setting a rate higher or lower than what is suggested
through the fund modeling, could mean that the assumptions or inputs may also need to change.

The Capital Improvement Program, which is one factor in establishing rate recommendations, is also
used to advantageously position the City for grants. A thorough list of capital projects is needed, as
granting agencies require that all projects must be listed in the City's adopted Capital Improvement
Program in order to be eligible for grants. Grant funding for Water and Sewer are normally rare and
difficult to obtain, but the City has been very successful in obtaining grants for Surface Water projects.
The City's current and proposed utility fees compare well in the region. With the proposed increases,
the City still ranks in the mid-range if not lower, even without taking into account the corresponding
increases that will occur in the other cities. The magnitudes of the proposed rate increases are also
reasonable; as smaller rate increases more frequently helps the City avoid the need to implement more
significant, catch-up increases in the future.
Exhibit A shows Cascade Water Alliance's proposed increases in 2023 and 2024.
Exhibit B is a rate matrix of all proposed utility rate increases for residential customers.
Exhibit C is King County Ordinance No 19447, providing sewage treatment costs for 2023.
Exhibit D-1 to D-3 shows a comparison of adjoining cities and their water rates along with the Water
Model from the Proposed 2023-2028 CIP.
The overall estimated additional monthly cost of the proposed City rate increases across all three
utilities (Water, Sewer and Surface Water) is $4.73, with an additional $2.84 due to a King County
passthrough. Further, the proposed rate increases are all below the recent inflation threshold of 9.5%.
WATER
Public Works analyzed the operational and capital needs of the Water Enterprise Fund in determining
the proposed fees. In addition, the City needs to account for Cascade Water Alliance's (CWA)
wholesale water rates that are set to increase by 2.2% in 2023 and 2.2% in 2024 (Exhibit A). A small
increase is being proposed to the base rates on residential, multi -family and commercial/ industrial
customers as well as increases to water consumption fees in winter only. Fire Protection service
charges are flat fees every month and will be increased in in 2023 & 2024.
Tukwila's residential water rates currently rank between 26 and 30 out of 30 (depending on pipe size) in
regional jurisdictions, and as rates will increase across the board, the estimate is that Tukwila will
continue to be lower as our neighboring cities. Even with the proposed water rate increases over the
next six years as shown in the Water model, the water fund shows a drawdown nearly in 2023 through
2025 and is at risk of not meeting the 20% reserve policy in the future. More competitive water rates will
allow the City to complete more capital projects annually, purchase a new reservoir, and combat
depreciating infrastructure.

Even with the proposed rate increases, Water provided by the City is still the cheapest source of water
within city limits. For instance, a gallon of water costs less than half a penny and filling the average
bathtub will cost a Tukwila consumer roughly 14 cents. Further, Highline Water District and Water
District 125, the two other main water providers to Tukwila residents, project to cost an average of
almost $6.00 more monthly per residential household in 2023.

The proposed rate increases would cost the average residential an additional $2.82 monthly, or another
26 cents per 748 gallons of water.
SEWER
King County Ordinance No. 19447 adopted a 5.75% rate increase in the King County sewage disposal
fees for 2023. The King County sewer rate will increase from $49.27 to $52.11 per residential customer
equivalent per month in 2023. There will likely be another rate increase by King County of 5.75% in
2024. Exhibit C is King County Ordinance No. 19447 for the 2023 rates.
Tukwila's sewer base rate will increase at a smaller rate of 3.3% annually in 2023 and 2024 in
accordance with the rate model that analyzes the City's operational and capital needs. The City's sewer
rate will increase to $31.00 per residential connection and $57.02 for up to 750 cubic feet or fraction
thereof for commercial/industrial customers in 2023. This results in a net increase of 4.54%. Exhibit D-2
shows a comparison of adjoining cities and their residential sewer rates, along with the Sewer Model
from the Proposed 2023-2028 CIP.
The proposed rate increases would cost the average resident $3.84 monthly, with $2.84 of that due to
King County's rate increase.

SURFACE WATER
Tukwila's surface water base rate is scheduled for an increase in 2023 and 2024. The City's surface
water rate will increase from $204.00 to $215.00 in 2023 and from $215.00 to $226.00 in 2024 per
residential parcel, per year. Commercial rates will range from $257.38 to $2,157.44 per 4,356 square
foot for all other parcels in 2023 and $270.25 to $2,265.31 in 2024.
Exhibit D-3 shows a comparison of surface water fees with other cities in the region along with the
Surface Water Model from the Proposed 2023-2028 CIP. The City's proposed residential rates for 2023
and 2024 are well below the 2022 average rate of $262.86.
If Council were not to adopt the proposed rate increases, the City would either have to eliminate
surface water capital projects, reduce staff allocation, or reduce reserves. Doing so would mean that
the City would fall behind on its infrastructure needs or would need to increase the rate more
substantially in subsequent years.
Surface water fees are processed by King County and collected with property taxes. The proposed
increases would cost the average resident an extra $0.91 monthly.

Parties agreed to: Dow Constantine
ELECTRONIC RECORD AND SIGNATURE DISCLOSURE
From time to time, Carahsoft OBO King County ITD (we, us or Company) may be required by
law to provide to you certain written notices or disclosures. Described below are the terms and
conditions for providing to you such notices and disclosures electronically through the
DocuSign, Inc. (DocuSign) electronic signing system. Please read the information below
carefully and thoroughly, and if you can access this information electronically to your
satisfaction and agree to these terms and conditions, please confirm your agreement by clicking
the `I agree' button at the bottom of this document.
Getting paper copies
At any time, you may request from us a paper copy of any record provided or made available
electronically to you by us. You will have the ability to download and print documents we send
to you through the DocuSign system during and immediately after signing session and, if you
elect to create a DocuSign signer account, you may access them for a limited period of time
(usually 30 days) after such documents are first sent to you. After such time, if you wish for us to
send you paper copies of any such documents from our office to you, you will be charged a
$0.00 per -page fee. You may request delivery of such paper copies from us by following the
procedure described below.
Withdrawing your consent
If you decide to receive notices and disclosures from us electronically, you may at any time
change your mind and tell us that thereafter you want to receive required notices and disclosures
only in paper format. How you must inform us of your decision to receive future notices and
disclosure in paper format and withdraw your consent to receive notices and disclosures
electronically is described below.
Consequences of changing your mind
If you elect to receive required notices and disclosures only in paper format, it will slow the
speed at which we can complete certain steps in transactions with you and delivering services to
you because we will need first to send the required notices or disclosures to you in paper format,
and then wait until we receive back from you your acknowledgment of your receipt of such
paper notices or disclosures. To indicate to us that you are changing your mind, you must
withdraw your consent using the DocuSign `Withdraw Consent' form on the signing page of a
DocuSign envelope instead of signing it. This will indicate to us that you have withdrawn your
consent to receive required notices and disclosures electronically from us and you will no longer
be able to use the DocuSign system to receive required notices and consents electronically from
us or to sign electronically documents from us.
All notices and disclosures will be sent to you electronically
Unless you tell us otherwise in accordance with the procedures described herein, we will provide
electronically to you through the DocuSign system all required notices, disclosures,
authorizations, acknowledgements, and other documents that are required to be provided or made
available to you during the course of our relationship with you. To reduce the chance of you
inadvertently not receiving any notice or disclosure, we prefer to provide all of the required
notices and disclosures to you by the same method and to the same address that you have given
us. Thus, you can receive all the disclosures and notices electronically or in paper format through
the paper mail delivery system. If you do not agree with this process, please let us know as
described below. Please also see the paragraph immediately above that describes the
consequences of your electing not to receive delivery of the notices and disclosures
electronically from us.

NOTES TO WATER ENTERPRISE FUND
1) Rates reflect increases of 7.5% in 2023, 7.5% in 2024, and 5%14% in 2025 through 2028.
These rate increases are essential to sustain our reserve balance and cover any possible
increases from Cascade Water Alliance (CWA). We will continue to review the annual rate
model to confirm that the proposed increases are necessary.
Future water purchased at additional costs will be passed on to ratepayers. We have identified
Cascade Water Alliance's revenues and expenditures to better reflect the actual water charges
and the respective increases. CWA has proposed rate increases of 2.2% in 2023 and 2.2% in
2024.
2) Connection fees are estimated for the Allentown/Foster Point and Duwamish projects.
3) Cascade Water Alliance is split out to identify the actual costs of purchased water. CWA has
scheduled increases in their six-year planning model that will affect our water rates.
4) Debt schedule includes Public Works Trust Fund (PWTF) loans and Bonds.
Water Debt Service includes: Expires 2023 2024

Total $323,804.27 $324,045.67
5) An Interfund Utility Tax was approved in October 2009 for the water, sewer, and surface
water utilities. Gross revenues are currently taxed 10% through December 31, 2027.
6) The Working Capital Reserve Fund's policy was updated in 2012 per Resolution No. 1774 to
maintain an adequate fund balance in each of the enterprise funds. For the Enterprise Funds,
the unrestricted fund balance shall equal or exceed 20% of the previous year's revenue,
exclusive of significant non-operating, non-recurring revenues.
7) The Senior Water/Sewer Engineer's salary and benefits are split evenly between the water
department and the sewer department. For 2023 and 2024, Technology staff will continue to
charge at 22% for the GIS Coordinator and 10% for the Information Systems Project Analyst.
Water Enterprise Fund
The City's Enterprise Funds account for utility operations that are self -
supported through user charges. The utilities are financed and operated
like a private business enterprise which requires periodic determination of
revenues earned; expenses incurred, and net income for capital
maintenance, public policy, management control and accountability. The
Water Fund accounts for operations and capital improvements to provide
water to a portion of City residents. King County Water District 125 and
Highline Water District also supply water to City residents.

NOTES TO SEWER ENTERPRISE FUND
1) King County Metro sewer and Tukwila's sewer have been split out to present the revenues
separately. Metro increases will be passed through to the sewer ratepayers. King County Metro
sewer fees will increase 5.75% in 2023 per KC Ordinance No. 19447 and we have factored in
potential King County increases for 2024 through 2028.
2) 3 percent increases are proposed for Tukwila sewer in 2023 and 2024. We will continue with
the annual rate model review to confirm that the proposed increases are necessary.
3) Sewer connection fees for Allentown Phase I and Allentown/Foster Point Phase II.
4) King County Metro Sewer treatment fees are passed through to ratepayers.
5) City's basic operation and maintenance costs.
6) Includes the Public Works Trust Fund (PWTF) Loan and the 2006 Bond for the Allentown/Foster
Point Phase II Sewer Improvement Project.
Sewer Debt Service includes: Expires 2023 2024

7) An Interfund Utility Tax was approved in October 2009 for the water, sewer, and surface water
utilities. Gross revenues are currently taxed 10% through December 31, 2027.
8) The Working Capital Reserve Fund's policy was updated in 2012 per Resolution No. 1774 to
maintain an adequate fund balance in each of the enterprise funds. For the Enterprise Funds,
the unrestricted fund balance shall equal or exceed 20% of the previous year's revenue,
exclusive of significant non-operating, non-recurring revenues.
9) The Senior Water/Sewer Engineer's salary and benefits are split evenly between the water
department and the sewer department. For 2023 and 2024, Technology staff will continue to
charge at 22% for the GIS Coordinator and 10% for the Information Systems Project Analyst to
assist with the GIS Inventory of the sewer fund. The Sewer fund is also splitting a GIS
Technician position with the Surface Water fund.
Sewer Enterprise Fund
The City's Enterprise Funds account for utility operations that are self -
supported through user charges. The utilities are financed and operated like
a private business enterprise which requires periodic determination of
revenues earned; expenses incurred, and net income for capital
maintenance, public policy, management control and accountability. The
Sewer Fund accounts for operations and capital improvements to provide
sanitary sewer to a portion of City residents. Valley View Sewer District also
provides sewer in the City.

NOTES TO SURFACE WATER ENTERPRISE FUND
1) Reflects proposed rate increases of 5% in 2023 through 2028, excluding a 3% increase in
2027. We will continue with the annual rate model review to confirm that the proposed Surface
Water rate increases are necessary.
The National Pollution Discharge Elimination System (NPDES) permit required by the State
Department of Ecology is having a significant impact on the Surface Water fund.
2) Potential grants and/or bond revenue. Included is the estimated Department of Ecology grant
for NPDES and King County Flood Control District Opportunity grants as well as significant
grant funding for the Nelsen Side Channel, the Storm Quality Retrofit Project, S 131st PI
Drainage Improvements, the Gilliam Creek Fish Barrier Removal Project and the Chinook
Wind Project.

4) An Interfund Utility Tax was approved in October 2009 for the water, sewer, and surface water
utilities. Gross revenues are currently taxed 10% through December 31, 2027.
5) The Working Capital Reserve Fund's policy was updated in 2012 per Resolution No. 1774 to
maintain an adequate fund balance in each of the enterprise funds. For the Enterprise Funds,
the unrestricted fund balance shall equal or exceed 20% of the previous year's revenue,
exclusive of significant non-operating, non-recurring revenues.
6) Cost of engineering to support capital projects, NPDES, and operation efforts in-house. For
2023 and 2024, Technology staff will continue to charge 22% for the GIS Coordinator and
10% for the Information Systems Project Analyst to assist with the GIS Inventory of the
Surface Water fund. The Surface Water Fund is also hiring a GIS Field Technician (split with
Sewer) and another NPDES Inspector.
Surface Water Enterprise Fund
The City's Enterprise Funds account for utility operations that are self -
supported through user charges. The utilities are financed and operated like
a private business enterprise which requires periodic determination of
revenues earned; expenses incurred, and net income for capital
maintenance, public policy, management control and accountability. The
Surface Water Enterprise Fund accounts for operations and capital
improvements for the City's storm drainage and surface water management
function. Surface Water projects are required to meet Federal, State and local
mandates. The largest contributor to the surface water enterprise fund is the
City of Tukwila.
