Click/tap the arrows below to learn more.
Lack of sufficient rate revenue has resulted in deferred maintenance and aging infrastructure—leaving the system vulnerable to failure.
The system reduces property damage from flooding and pollution in local waterways by collecting, and removing rain and irrigation water from properties.
Rates have not increased since 1992—that’s 34 years—even though costs, state and federal regulations, and the size of the system have increased.
By fiscal year 2027–28, our stormwater utility will face an approximate $5 million annual shortfall, leading to higher flood risks, more pollution in waterways and potential costly regulatory fines.
The increase would adequately fund your stormwater services, and allow for long-overdue infrastructure repairs and improvements.
The cities of Elk Grove and Sacramento stormwater rates are higher now than Stockton's would be even after the five-year gradual increase.
If property owners or customers of record approve proposed rates
City will invest revenues in system maintenance, repairs and infrastructure replacements.
This will minimize flooding and protect your property.
If property owners or customers of record do not approve proposed rates
City will not be able to maintain and fix system failures, and will have reduced ability to respond to emergency flood calls.
This will increase potential for flooding, and negatively impact your property.

Stormwater 101
Let’s get familiar with terms we’ll use throughout the Online Open House
What is “Stormwater?”
- Stormwater is water runoff.
What is Water Runoff?
- Water Runoff includes any water that flows off your property—rainwater, water from sprinklers, water from hoses, etc.—along with water runoff from commercial/ industrial purposes.
How is Water Runoff Harmful to Our Community?
- Property Damage Risk: Water runoff can flood streets and properties, if the stormwater system is not working properly.
- Water Quality Risk: As water runoff flows, it collects pollutants—like debris and automobile oil—and runs into local storm drains. Any trash and hazardous waste that enters the stormwater system is carried directly into local waterways.
- Pollution Risk: When pollutant levels rise, it becomes more expensive for the City to treat drinking water from local waterways.
What Does the City of Stockton Stormwater System Do?
- This large network of storm drains, pipes, pump stations and stormwater holding ponds, collects water runoff from properties and moves it into local waterways such as rivers, creeks, sloughs and the Delta.
What are Common Sources of Water Runoff Pollution?
- Sediments, dirt, sand, silt and construction waste
- Pet waste
- Pesticides and fertilizers
- Automobile fluids like oil, grease, gasoline and antifreeze
- Grass clippings, leaves and other yard waste
- Metals
- Household hazardous wastes (HHW) like paints and solvents
- Debris such as plastic bags, six-pack rings, bottles and cigarette butts
Get to Know Your Stormwater System
Your stormwater system protects your property
Your stormwater system prevents flooding and related damage to properties through collection and removal of water runoff. It also keeps pollutants like trash, oil, chemicals, and sediment from flowing into local rivers, creeks, sloughs and the Delta.
The land in Stockton is generally flat and mostly developed, so water runoff can’t drain naturally in most places. Because there’s nowhere for the water to go, it must be physically removed to keep it from backing up and flooding streets, homes and other buildings.
Stockton’s Stormwater—By the Numbers
The City operates and maintains a large network of storm drains, pipes, pump stations and stormwater holding ponds to collect water runoff from properties and move it into local waterways (rivers, creeks, sloughs and the Delta).
(also known as storm drains)
We’re Working For You
The City employs 20 highly trained staff who manage operations, maintenance and emergency response for your stormwater utility. In 2024 alone, stormwater utility crews were responsible for:

What’s the Problem?
Your stormwater system is at a breaking point
Lack of sufficient rate revenue has resulted in deferred maintenance and aging infrastructure—leaving the system vulnerable to failure.
Insufficient funding
Today, rate revenues do not cover the total cost of providing service such as operations, maintenance, and important repairs and improvements.
- Stormwater utility revenues come from stormwater rates and are approximately $6 million per year.
- Miscellaneous revenue is reimbursements, interest income, inspection fees, penalties and fines, etc. and are approximately $900,000 per year.
- The current stormwater rate—$2.10 per month for each Equivalent Dwelling Unit (about $25 per year for a typical single-family home)—was set in 1992, 34 years ago. It has never been increased, even though costs have gone up, state and federal regulations have expanded, and the stormwater system has grown.
Additional funding required
Additional rate revenue is required to avoid service level cuts and an increasing likelihood of system failures.
By fiscal year 2027–28, our stormwater utility will face an approximate $5 million annual shortfall, leading to higher flood risks, more pollution in waterways and potential costly regulatory fines.
As an enterprise fund of the City, stormwater utility services must be self-supporting. In other words, the costs must be covered through rate revenues paid by the property owners and customers of record who receive service. This is required by the California Constitution Article 13D, also known as Proposition 218.
- Rates collected for services are only used to pay for operating, maintenance and capital improvement project costs for stormwater services—meaning those funds are not mixed with the City’s general funds.
Deferred maintenance and aging infrastructure
Your stormwater utility has been underfunded for many years, and now significant portions of your stormwater system are at critical risk of failure. Revenues do no cover the costs for system maintenance and necessary infrastructure improvements. That’s a big problem because the stormwater system is aging.
The consequences of aging and insufficient infrastructure were especially obvious in early 2023 when Stockton received over half of its average annual rainfall in just 17 days.
- Stormwater system was overwhelmed
- Streets were flooded
- Several pump stations were knocked out of commission and could not be immediately repaired
This resulted in flood damage to cars, homes and businesses (e.g. Quail Lakes area), as well as pollutants in the stormwater system. And the problems could worsen!

How Do We Fix the Problem?
Stormwater utility problems can only be fixed with adequate funding
Adequate funding is necessary to replace old, failing infrastructure and keep up with ongoing maintenance.
Vulnerable areas in need of repairs and improvements
The City’s 2023 Stormwater Master Plan identifies areas vulnerable to potential system failures and outlines $285 million in capital improvements (projects) to reduce the risk of flood damage to properties. Planned projects include repairs and improvements to pump stations, discharge pipelines, and storm drains.
System improvements are in addition to day-to-day maintenance, which includes:
- Inspecting and cleaning storm drains, pipes and pump stations
- Inspecting construction, industrial and commercial properties to reduce improper and/or illegal disposal of hazardous waste
- Responding to emergency calls to clear storm drains and flooded streets

What’s My Proposed Cost?
The City is proposing a gradual, five-year rate adjustment
The proposed rate adjustment would start August 1, 2026, and cover the cost of providing service.
Your stormwater rates will remain lower than current rates of neighboring cities
The proposed rate adjustments would adequately fund your stormwater services, comply with water quality requirements, and allow for long-overdue infrastructure repairs and improvements.
Even after five years, your stormwater rates will remain lower than current rates of neighboring cities like Sacramento and Elk Grove.
The City hired HDR, an engineering consulting firm, to conduct a third-party analysis of current and future revenue requirements. These include cost recovery for operations, maintenance, capital improvement projects and regulatory compliance.
The current stormwater rate is $2.10 per month per Equivalent Dwelling Unit (approximately $25 per year for a typical single-family home). This rate hasn’t increased since 1992—that’s 34 years!
If the five-year rate adjustment is approved by property owners and customers of record, the stormwater rate would generate approximately $5 million in funding for fiscal year 2027–28, fully covering costs for operations, maintenance, regulatory compliance and delayed capital improvements.
Even after year five, your monthly stormwater utility rate will be lower than current rates for other cities like Sacramento, Elk Grove, among others. These agencies may also have additional rate increases before the City of Stockton reaches year five of the proposed rate adjustments.
Summary of Proposed Maximum Stormwater Rates
Phased over a five-year period beginning August 1, 2026, and each July 1 thereafter through 2030, if approved by ratepayers and adopted by City Council.
New rates for single-family and multi-family residential properties will be:
| Start Date | Cost Per Month | Cost Per Year |
|---|---|---|
| August 1, 2026 | $3.85 | $46.20 |
| July 1, 2027 | $5.60 | $67.20 |
| July 1, 2028 | $6.85 | $82.20 |
| July 1, 2029 | $7.85 | $94.20 |
| July 1, 2030 | $8.10 | $97.20 |
What Happens Next?
As required by California Proposition 218, the City of Stockton will send all stormwater property owners or customers of record a notice about the public hearing on proposed stormwater rate changes
The Process
Approving your new stormwater rates is a two-step process:
Protest Hearing
The City sends a notice of the proposed rates and schedules a public protest hearing. Property owners or customers of record may submit written protests any time before the hearing closes.
- If more than 50% of property owners or customers of record submit protests, the rate setting process cannot move forward
- If 50% or fewer protest, the City Council may proceed to Step 2
Public Protest Hearing
Tuesday, March 31, 2026 at 5:30 p.m.
City of Stockton Council Chambers
425 N. El Dorado Street, Stockton, CA 95202
How to Submit a Written Protest
-
Written protests must be delivered in person or by mail
before the close of the public hearing on Tuesday, March
31, 2026, to:
Office of the City Clerk City Hall
425 N. El Dorado Street, Stockton, CA 95202
-
Written protests must include the following:
- Name and signature of the person submitting the written protest
- Property address or Assessor’s Parcel Number (APN)
- Clear statement protesting the proposed rate adjustments (not necessary to give a reason, opposition alone is sufficient)
- Only one protest per parcel will be counted
- Protests may also be submitted in person to the City Clerk during the public hearing
Election and Public Hearing
The City Council may then direct staff to mail ballots to all property owners or customers of record, starting a minimum 45-day election period that ends with a public hearing.
- Proposed stormwater rates may be adopted if more than half of the returned ballots are marked “yes”
- Proposed stormwater rates cannot be adopted if more than half of the returned ballots are marked “no”
Your input matters
If property owners or customers of record approve proposed rates
- You will pay an increased rate for stormwater services over a five-year period starting August 1, 2026
- Rate revenues will cover the cost of providing service
- By law, the City can only use rate revenues to fund the cost of stormwater utility services that include operations, maintenance, capital improvement projects and regulatory compliance
- City will prioritize deferred maintenance and capital improvement projects meant to reduce flood damage as identified in the Stormwater Master Plan
- Even in year five, your monthly stormwater rate will still be less than current rates in neighboring cities like Sacramento and Elk Grove
If property owners or customers of record do not approve proposed rates
- Existing rate revenues do not cover the cost of providing service
- Stormwater utility reserve funds will be eliminated by fiscal year 2026–27
- Stormwater utility will begin fiscal year 2027–28 with an annual deficit of approximately $5 million
-
Existing levels of service will be significantly
reduced, meaning an increased risk of:
- More localized flooding, even in areas where flooding has not occurred in the past
- Reduced emergency response to localized flooding and system failures
- Potential increase of flood damage to properties
- Increased likelihood of higher contaminant loads and trash in local rivers, creeks, sloughs, and the Delta
- Additional delays of capital projects and deferrals of annual maintenance
- Reduced cleaning of storm drains
- Catastrophic system failures (e.g. pump stations)
- Potential fines for violation of state and federal water quality regulations
