Recommended Motion
Motion to adopt Resolution 4036 to amend the 2026 Fee Schedule to adjust water utility rates as presented.
Summary/Background
The 2026 fee schedule adopted by Council on December 9, 2025, and amended by resolution 4032 on 1/13/2026 and resolution 4034 on 3/10/2026 included water rate increases of CPI
at 2.7%. During subsequent study sessions, Council authorized an additional 0.03% increase in the fixed meter charges for single family residential and duplex customers and the
consumption charges for all user classes (excluding irrigation), bringing the total increase in fixed meter charges for single-family and duplex customers and consumption charges for all
non-irrigation user classes to 3.0% for 2026.
At a February 17th study session, Council was presented with three options for irrigation rates. Council directed staff to work with the consultant (FCS Group) to provide further options
for irrigation rates, and at a March 31, 2026, special meeting, Council was presented with two additional irrigation rate options for consideration and recommendation. At that meeting,
Council authorized staff to implement Option 4 of the proposed irrigation rate options for 2026.
Option 4 updates the irrigation tiers and pricing by reducing the rate schedule from a 4-tier to a 3-tier model and provides the lowest rate option for single-family customers. Under
option 4, 87.2% of irrigation customers would be charged Tier 1 rates only, 6.0% would be charged Tier 1 and Tier 2 rates and 6.8% would be charged under all three tiers, resulting in
significant savings for customers until they reach 500,000 CF or more of water usage in a single billing cycle. The current and option 4 irrigation rate schedules are shown in the table
below.
Current Tiers CF Rate/100 CF Option 4 Tiers CF Rate/100 CF
Tier 1 0 - 1,000 $0.50 Tier 1 0 - 50,000 $1.60
Tier 2 1,001 - 5,000 $1.51 Tier 2 50,001 - 100,000 $2.50
Tier 3 5,001 - 10,000 $3.00 Tier 3 Over 100,000 $4.50
Tier 4 Over 10,000 $4.04
The 2026 fee schedule needs to be updated to the new fees before they can be charged. The attached resolution identifies the updates to the fees that will be made effective May 1,
2026.
Fiscal Consideration
An additional 0.03% increase to fixed meter charges for single-family and duplex customers and usage charges for non-irrigation customer classes, coupled with the option 4 irrigation
rate structure shown above results in significant progress towards achieving cost of service among all user classes. Under Option 4, duplex and multi-family customer classes remain
slightly under cost of service while irrigation remains above cost of service but is significantly lower by the end of the forecast period.
These changes result in a forecasted revenue loss of $420k in 2026 compared to an across-the-board increase of 3% to all customer classes and no movement towards achieving cost of
service alignment. These changes move us in the direction of cost-of-service alignment across user classes over the coming years, ensures system-wide ability to complete capital
projects while also providing the lowest rate option to single-family customers and reducing the cost to irrigation customers.
FINAL COML Council Packet 4-21-26. Page 2 of 264
The 2026 adopted fee schedule needs to be amended to reflect the adjustment to water utility rates and the new irrigation rate schedule as approved by Council on March 31, 2026. If
the fee schedule is not amended, the fees would be charged inaccurately resulting in inaccurate revenue collections.

Survey in the City of Moses Lake
April 2026
FINAL COML Council Packet 4-21-26. Page 15 of 264
Fulcrum Strategy Group 2
A survey with a random sample is like tasting soup; if well -stirred, you
get a good sense of the flavor in a spoonful without eating the whole pot
Random Sampling
Start with a known universe, in this case all eligible voters in Moses Lake
Shuffle this universe and select respondents at random. When we do,
responses fall within a calculable margin of error. We achieve that by…
Reducing survey bias (generic company, generic survey intro)
Making multiple attempts to reach selected respondent
Replacing respondents with a random selection
Monitoring demographic distribution against known characteristics
Weighting final results when necessary (weighting was not needed)
FINAL COML Council Packet 4-21-26. Page 16 of 264
Fulcrum Strategy Group 3
The company contacting respondents and survey introduction are intentionally generic; therefore if
someone refuses, they are not doing so based on the topic
Respondents may theorize about the sponsor's identity at some point during the survey but are
never informed during the interview process
Results include data from respondents who completed the entire survey, meaning results are not
biased from partial answers
Survey design and administration features including:
o Respondents offered balanced scale options
o A question order that releases a little bit of information at a time
o Randomized question orders, and
o Interviewers/web survey techniques offer the same clarifications each time.

ML owns and operates wide range of rec facilities/park land than other cities. I
support City finding ways to get out of owning/operating some of these facilities
to reduce the budget
Road construction is a big budget item. I support cutting back on building more
sidewalks and other road improvements
Some roads might get rougher w/more potholes, I would support cutting back on
pavement maintenance to trim the budget
Budget opportunity is cut back a bit on police patrols/traffic enforcement; PD
would spend less time patrolling streets/enforcing traffic laws. I would support
cutting back on police patrols/traffic enforcement
FD is major part of City budget. I would support having slightly longer fire
response times to reduce the budget
I like that ML has lots of park space/rec programs. Would rather pay more taxes
to keep what we have open and running, even if taxpayers subsidize
If we are going to pay more in taxes, I would rather raise taxes to pay for
police/pub safety
If we had to raise taxes to close budget gap, sales taxes are best because lots of
people in the County come to ML to shop, which means we would not be the only
ones paying new taxes

Q33. As you heard, raising taxes are one option for helping close budget gaps. The City could raise the
sales tax by 0.1% to fund cultural programs like the City’s museum and other arts programs. Would you
support/oppose this sales tax for cultural programs?

DRAFT
Financial Sustainability Plan
Guiding Principles
The following guiding principles should be considered as part of the introduction to the
Financial Sustainability Plan document:
1.Align Resources with Priorities. Financial resources should be allocated first to
core and basic programs and City Council priorities. Any remaining funds to
enhanced programs should be allocated based on how well they advance the City
Council’s top priorities and the needs and wants of the community.
2.Balance Operating Revenues with Operating Expenditures. Only ongoing
revenues should support ongoing expenditures. Do not use one-time funds (e.g.,
grants or reserves) to support recurring costs.
3.Practice Fiscal Neutrality. Enforce a "zero-sum" policy: every proposed new
position or program must be oƯset by an equal expenditure cut or a new revenue
source. To ensure long-term viability, all proposals must include fully-loaded costs
and be integrated into the multi-year financial forecast. This prevents short-term
budget availability from masking long-term sustainability risks.
4. Create a Shared Stewardship Model. Government is only one part of a thriving
community. Moses Lake is home to resourceful, generous, and civic-minded
residents and businesses who are eager to contribute. By shifting toward a model of
shared stewardship—where volunteers, churches, nonprofits, and community
groups take an active lead in programs and amenities in partnership with the City—
we foster a deeper sense of pride and ownership while directly enhancing the City’s
financial sustainability.
Tapping into the expertise and labor of our local residents and partners can help us
shift and reduce costs. This collaborative strategy should ease the City’s financial
FINAL COML Council Packet 4-21-26. Page 34 of 264
burden by allowing the community to step up and fill gaps that the City has
historically been expected to provide.
5.Maximize Economic Resilience. Strong cash reserves and diversification of
revenues will provide stability through downturns. Some of Moses Lake’s revenues
are elastic and more volatile and subject to economic fluctuations. To prepare for
downturns and improve budget flexibility, keep ending fund balances of the General
Fund and Street Fund to at least the minimum percentage of annual expenditures as
established by the City Council. Set a target minimum fund balance for the Rainy
Day Fund and build up to that target.
6.Take the Long View. One-year budgets do not show the full picture and can mask
structural issues. Forecasting out at least six years provides a better view of budget
trends and allows policy makers to be proactive and get ahead of problems. The
financial forecast should be updated and reported to the City Council at least
annually.
7.Maintain Capital Assets. Assess capital asset needs and allocate funds to
maximize the lifecycle of those assets. Allocate the necessary capital replacement
funds every year to eliminate deferred maintenance and avoid unplanned spikes as
infrastructure, equipment, and building systems age and need to be replaced.
8.Use Public Funds EƯiciently and Responsibly. Continuously improve eƯiciency
and reduce waste and redundancy. Maximize the value of every dollar through
improving purchasing practices, productivity, and how services are delivered (e.g.,
contracting vs. in-house).
9.Cultivate Agility and Opportunity. To remain truly nimble, the city must maintain
the capacity to seize emerging opportunities and respond to unforeseen challenges.
While lean operations are essential, true agility requires a strategic buƯer in both
staƯing and budgeting. We will advance this goal by building up the Strategic
Opportunities Fund and managing workloads and priorities to ensure staƯ have the
necessary bandwidth to pivot when circumstances shift.
FINAL COML Council Packet 4-21-26. Page 35 of 264
10. Prioritize Organizational Health and Talent Retention. Fiscal sustainability should
not come at the expense of City employees. Our city team is high performing and
operates at near-full capacity; therefore, reducing staƯ without a corresponding
decrease in service levels creates unsustainable workloads and erodes morale. To
remain a competitive employer, the City must maintain compensation and benefits
that align with comparable municipalities. Protecting these standards is essential
for attracting and retaining the high-quality talent necessary to serve our community
eƯectively.
11. Transparency and Accountability. As we have done so far, include the public in the
Financial Sustainability Plan. Update the plan regularly. Using our communication
channels, report on the plan’s progress and status to the City Council and the
public. Ensure the FSP is clear, accessible, and understandable to our residents.

RESOLUTION NO. ______
A RESOLUTION OF THE CITY OF MOSES LAKE, WASHINGTON, ESTABLISHING
A VOLUNTARY SEPARATION INCENTIVE PROGRAM FOR ELIGIBLE CITY OF
MOSES LAKE EMPLOYEES
Recitals:
A. As a strategic management tool to align the City’s workforce with current budgetary realities
and long-term operational goals, the City Council desires to establish a Voluntary Separation
Incentive Program (VSIP).
B. The City deems it is in the City's best interest to provide an incentive for eligible employees,
defined in Section 1.B, to voluntarily separate or retire from the City.
C. The purpose of a voluntary separation program is to reduce compensation costs and full-time
employee levels, facilitate redeployment, reorganization, and other efforts to make more efficient
and effective use of the City's limited resources, avoid the disruption and administrative costs
associated with involuntary layoffs (reductions in force), and provide the City Manager with the
flexibility to reallocate resources to high-priority core and basic city services.
RESOLVED:
Section 1. Program Establishment and Definitions
A. Voluntary Separation Incentive Program Description. The City hereby establishes a
Voluntary Separation Incentive Program (Program, or VSIP) for Eligible Employees as defined
in Section 1.B.
B. “Eligible Employees" All regular full-time and regular part-time employees who have
completed at least five years of continuous service and have not previously provided written
notification of upcoming retirement.
C. “Ineligible Employees”: City Manager and Department Directors. Regular
employees with less than five years of continuous service. Temporary/seasonal employees,
employees currently under a performance improvement plan (PIP), or those who have already
submitted a notice of resignation or retirement.
D. The "Date of Separation" is the final day of an employee's employment with the
City, as specified in the voluntary separation agreement described in Section 4 of this Resolution.
E. The Program is subject to collective bargaining obligations as required by RCW 41.56.
FINAL COML Council Packet 4-21-26. Page 37 of 264
Section 2. Basic Provisions
A. Participation in the Program shall not be based on protected class status, protected
activity, or other unlawful factors.
B. Participation in the Program is voluntary. Eligible Employees choosing to participate
in the Program must acknowledge in writing that their decision to participate is voluntary.
C. Voluntary separation will be subject to all applicable terms and conditions of labor
agreements in effect on the date the Eligible Employee applies for voluntary separation. No
Eligible Employee shall have a contractual right to an incentive offered through this Program.
D. Eligible Employees who apply and are approved for voluntary separation under the
Program will receive:
1. Participants whose applications are accepted will receive a one-time cash Separation
Incentive Payment exclusive of additional pays such as longevity, out-of-class, lead pay
differential, call out pay, holiday premium, and overtime, based on their completed years
of service with the City of Moses Lake:
Years City Service Incentive Amount (Lump Sum)
5 – 10 Years 10 weeks of base salary
11 – 19 Years 15 weeks of base salary
20+ Years 21 weeks of base salary
Notwithstanding the above, the Incentive Amount for employees who are at PERS
retirement age and for employees with twenty or more years of experience working for
counties, cities, and/or the State of Washington is 21 weeks of base salary.
2. COBRA (Consolidated Omnibus Budget Reconciliation Act) Bridge: The City will
provide a one-time payment equal to [e.g., 3 months] of the employee’s current COBRA
premium rate to assist with the transition of health benefits.
5 – 10 Years 3 months
11 – 19 Years 4 months
20+ Years 5 months
Five months of the COBRA Bridge is also for employees who are at PERS
retirement age and for employees with twenty or more years of experience working for
counties, cities, and/or the State of Washington.
3. The City Manager may allow retirement-level leave cashouts and other retirement
benefits if employees opting for this program are at PERS retirement age. All other
benefits shall be paid out in accordance with current city policies, labor agreements, and
applicable state and federal laws.
E. The City acknowledges that Eligible Employees choosing to participate in the Program
may apply for unemployment compensation benefits following separation from the City. While
such employees may not qualify for unemployment benefits, the City will not object to such
FINAL COML Council Packet 4-21-26. Page 38 of 264
claim.
F. Voluntary separation payments will be paid in one (1) lump sum within three (3)
weeks of the Date of Separation based on the payroll cycle. Voluntary separation payments will
not be considered excess compensation and shall not increase an Eligible Employee's monthly
pension payout or the City's pension contribution rates.
G. Voluntary separation payments are subject to applicable tax withholdings but are not
considered income (average final compensation) for retirement purposes. In accordance with
Washington Department of Retirement Systems (DRS) rules:
• Non-Reportable Compensation: These incentive payments are for the purpose of
voluntary separation and are not for services rendered. Therefore, they are not reportable
compensation for PERS Plan 2 or 3 members and will not affect the employee's average
final compensation (AFC).
• PERS Plan 1 Exception: For Plan 1 members, if the incentive is calculated based
on "years of service," it may be deemed "earned over time" and trigger an Excess
Compensation bill to the City. The City reserves the right to cap or adjust Plan 1
incentives to avoid such liabilities.
H. Re-Employment Restrictions. To ensure the City realizes the projected cost savings,
any employee who accepts a VSIP incentive is prohibited from returning to work for the City of
Moses Lake—including as a regular employee, temporary employee, or independent
contractor—for a period of five (5) years from the Date of Separation.
Section 3. Approval Criteria.
Voluntary separation under this Program can be approved only by written agreement executed by
the City, the Eligible Employee and the labor union, if applicable. Labor unions will be given
notice of the proposed terms of any written agreement and be given the opportunity to negotiate
on behalf of their members. The voluntary separation agreement shall be approved by the City
Attorney and include indemnity and other waiver protections for the City. It shall also include
the Eligible Employee's acknowledged acceptance of the terms and conditions of the Program,
specify the cash-value of the Eligible Employee's incentive under Section 2.D, and designate the
final date of employment with the City (the Date of Separation).
Section 4. Notification and Separation Requirements
A. To be considered for participation in this Program, Eligible Employees must apply by
submitting an official application to the Human Resources Department within sixty (60) days of
the Effective Date of this Resolution. Employees who submit an official application by this
deadline will then be provided additional information, along with review periods as established
by law. Applications will be reviewed by administration and may be approved or denied
consistent with the purposes of the VSIP set forth in Recital C above. All decisions are subject
to the discretionary approval of the City Manager.
FINAL COML Council Packet 4-21-26. Page 39 of 264
B. The Date of Separation shall be no later than one hundred (100) days following
approval of the application, unless the City Manager determines that a later Date of Separation is
in the best interest of the City.
Section 5. Position Backfill
A. The City Manager shall determine whether a position vacated via the VSIP will be:
1. Eliminated from the budget;
2. Held vacant for a minimum of 12–24 months; or
3. Restructured at a lower salary grade or change in essential job functions;
4. Replacement at a lower salary grade/level.
.
B. Requests to backfill positions vacated through the Program are subject to review and
approval by the City Manager. Backfill requests that facilitate redeployment, reorganization,
and/or other efforts to make more efficient and effective use of the City's limited resources will
receive priority consideration.
Adopted by the City Council on _ , 2026.

and/or City Engineer, the Public Works Director and/or City Engineer may allow an
applicant to deviate from certain development standards contained in the WSDOT
Standard Specifications for Road, Bridge and Municipal Construction as revised by the
Community Street and Utility Standards, provided the proposal satisfies the evaluation
criteria. This alternative process is intended to promote well-designed and innovative
construction which may not strictly comply with the established standards and guidelines,
but which meets the intent of the standards and guidelines. In evaluating such a proposal,
the Public Works Director and/or City Engineer shall determine if the alternative design
FINAL COML Council Packet 4-21-26. Page 70 of 264
Community Street and Utility Standards – 20225 Page 13 of 125
provides equivalent or superior results than compliance with the established standards
and guidelines.
2. Basis for Deviation: The applicant shall provide plans and a written narrative describing
the deviation request to the Public Works Director and/or City Engineer for review. The
plans and narrative shall provide the Public Works Director and/or City Engineer
sufficient detail to determine if the proposed deviation will provide equivalent or superior
results than compliance with the established standards and guidelines. The Public Works
Director and/or City Engineer shall make their recommendations based on the following
criteria:
a. Unique characteristics of the property and surroundings and how they will be
protected or enhanced by the deviation;
b. Positive characteristics of the proposed deviation and whether the result could be
provided by compliance with the standards and guidelines;
c. Whether the proposed design mitigates impacts that could be caused by deviation
from the standards
d. Quality of proposed design and/or unusual circumstances;
e. Deviations shall not be approved that would be detrimental to the public health,
safety, or welfare; or that would be injurious to real property;
f. A deviation approval may require such conditions as may serve the objectives of
the requirement that is being deviated, insofar as is practical.
3. Process: Upon receipt of a complete application submitted on the public portal Deviation

City Street
City Street is any street within dedicated right-of-way, easement, or other public property
classified by federal functional classification including primary streets, secondary streets,
tertiary streets, and residential streetsArterials (Principal, Minor), Collectors (Major,
Minor, Rural), & Local Streets within the City limits.
The City Engineer shall classify all proposed City Streets and all City Streets that are
annexed after the publication of this edition, as either an primary street, secondary street,
tertiary street, or residential Arterial (Principal, Minor), Collector (Major, Minor, Rural),
or Local street.
Arterial – Principal, Minor
Roadways designated as principal arterials are typically major roads that are not
limited-access freeways. In Moses Lake, principal arterials are the main north-
south corridors that distribute traffic to freeway, minor arterials, collectors, and activity
centers. These facilities also serve travel between the City and neighboring
jurisdictions and focus on regional auto traffic. ADD DEFINITION FOR MINOR
ARTERIALS AS WELL. In Moses Lake Major Arterials provide two to four travel lanes and
have a posted speed limit between 30 and 60 miles per hour (mph). Examples of these
arterials are State Route 17, State Route 171, and S Pioneer Way.
Arterial – Principal
Principal arterials are roadways that service major activity centers and
have the highest traffic volumes and longest trip demands. They carry the highest
proportion of total urban travel on minimum mileage. Principal arterials
interconnect and provide continuity for major rural corridors to accommodate
FINAL COML Council Packet 4-21-26. Page 76 of 264
Community Street and Utility Standards – 20225 Page 19 of 125
trips entering and leaving urban areas and movement through the urban area.
They serve demand for intra-area travel between the central business district and
outlying residential areas.
Arterial – Minor
Minor arterials are roadways that interconnect and augment the higher-
level Arterials and serve trips of moderate length at a somewhat lower level of
travel mobility than principal arterials. They distribute traffic to smaller
geographic areas than those served by higher-level arterials. They also provide
more land access than principal arterials without penetrating identifiable
neighborhoods and urban connections to rural collectors.
Collector – Major, Minor, Rural
Urban Collectors are facilities in the denser, urban areas of the model that
cconnect and distribute cars between arterials and commercial or multi- family
residential land uses. Urban Collectors typically provide two travel l lanes
ADD DEFINITION FOR MAJOR AND MINOR. , with a posted speed limit of 20-50 mph. Examples of
Urban C Collectors are Road L NE, Randolph Road NE, and W Peninsula Drive.
Major – Collector
Major collectors serve both land access and traffic circulation in higher density
residential and commercial/industrial areas. They penetrate residential
neighborhoods, often for significant distances. Major collectors distribute and
channel trips between local roads and arterials, usually over a distance of greater
than three quarters of a mile. Their operating characteristics include higher speeds
and more signalized intersections.
Minor – Collector
Minor collectors serve both land access and traffic circulation in lower density
residential and commercial/industrial areas. They penetrate residential
neighborhoods, often only for a short distance. Minor collectors distribute and
channel trips between local roads and arterials, usually over a distance of less than
three-quarters of a mile. Their operating characteristics include lower speeds and
fewer signalized intersections.
Local Street
Local streets are all streets not classified as Arterial or Collector.
Commission
All references in the Standard Specifications to the term “Commission” shall be revised
to read “City of Moses Lake”.
