Stormwater

​Stormwater is rain that flows over streets, roofs, yards, and parking lots. This runoff would cause flooding, but Springfield has a stormwater system built to receive it and empty it to local waterways.

In the stormwater system, runoff enters storm drains, open channels, swales, and pipes and then flows to neighborhood waterways that train to the McKenzie and Willamette rivers. Stormwater is not cleaned before it reaches those waterways.

The City of Springfield manages stormwater to reduce flooding, protect public health, and meet state and federal requirements. This page is the main hub for the City’s Stormwater Team.

Why the City Manages Stormwater

River water quality is protected locally and nationally by the Federal Clean Water Act of 1972. It’s enforced by the Federal Environmental Protection Agency (EPA), the Oregon Department of Environmental Quality (DEQ), and Springfield city code which is adopted by Springfield City Council. Springfield’s Stormwater Team manages the permit to prevent river pollution. They provide education, technical assistance, and practical solutions so that community members protect local water quality.

The DEQ has found that some local waterways are “impaired,” including the Willamette River, the McKenzie River, and Camp Creek. Because Springfield has more than 65,000 residents and sends runoff to these rivers, the City is one of the agencies held responsible for working with the community to reduce water pollution.

Springfield’s stormwater system collects rain (urban runoff) and releases it into the McKenzie or Willamette River. The Stormwater Team does management and education for this important and easily overlooked part of the City’s infrastructure.

Springfield operates under a permit through the National Pollutant Discharge Elimination System (NPDES), issued by the DEQ. This permit from DEQ requires community members to reduce the pollution entering waterways and for the City to track and report our work toward that end.

The City’s Municipal Separate Storm Sewer System (MS4) plan explains how we meet these requirements. Our Total Maximum Daily Load Implementation Plan (TMDL IP) focuses on reducing specific pollutants in the Willamette and McKenzie river basins. These plans guide City work and connect with actions taken by residents, businesses, and builders.

Focus Areas for Stormwater Management

DEQ permits require the City to address the areas below. These target the main ways pollution reaches rivers and streams through stormwater.

Public Education and Outreach

Programs that inform and educate the public, business, industry, and government about the causes of stormwater pollution, the effects on local streams and rivers, and encourage behavior change that will reduce stormwater pollution and promote the health of the Willamette and McKenzie rivers.

Public Involvement and Participation

Programs that provide opportunities for the public to participate in the development, implementation, and modification of Springfield’s stormwater management program.

Illicit Discharge Detection and Elimination

Programs that improve water quality by preventing, proactively investigating (detecting, characterizing, and tracing), and removing illicit discharges to the stormwater system.

Construction Site Runoff Control

Programs that improve water quality by reducing or preventing soil erosion and implementing sediment control measures at construction sites through regulation, inspection, enforcement, and education.

Post-Construction Site Runoff for New Development and Redevelopment

Programs that improve water quality by developing and applying appropriate design and construction standards to development.

Pollution Prevention and Good Housekeeping (City Operations)

Programs that improve water quality by developing and applying appropriate design and construction standards to development.

NPDES MS4 Phase II Permit

The Federal Clean Water Act requires Springfield to apply for and maintain a permit under the National Pollutant Discharge Elimination System (NPDES) program. Springfield’s stormwater conveyance system is classified as a Municipal Separate Storm Sewer System (MS4). Springfield receives a Phase II permit because of the city’s size.

Springfield’s MS4 Annual Report

Springfield’s NPDES Permit requires the City to make sure it’s following each rule in the permit. The Stormwater Team shows that the City is meeting the requirements by sending this MS4 Annual Report to DEQ every year.

 

Stormwater Management Plan 2010 (SWMP)

Springfield’s stormwater programs and projects are outlined in our Stormwater Management Plan (SWMP), which is adopted by City Council.

Chapter 5 of the plan addressed the NPDES Permit from DEQ. It expired in 2011 and was updated by the MS4 Plan, 2022-24 below.

MS4 Plan 2022-24

Springfield’s MS4 Plan is informed by the NPDES Permit and outlines activities affecting stormwater throughout the City and its urbanized area. It helps us meet local water quality requirements.

Total Maximum Daily Load Implementation Plan (TMDL IP)

Outlines the City of Springfield’s several special programs to improve water quality in the Willamette and McKenzie rivers, specifically for temperature, bacteria, and mercury.

Total Maximum Daily Load (TMDL) Annual Report

The City’s annual report on its application of the TMDL Implementation Plan, listed above.

History Corner:
Springfield’s vision for cleaner rivers

In 1999, Mayor Bill Morrisette and the Springfield City Council adopted the ‘Seven Key Outcomes for Stormwater’ to guide the City’s vision for cleaner rivers.

Starting in 1990, Oregon’s largest cities with populations over 100,000 were required to manage stormwater under state and federal stormwater permits.

By 1999, Springfield City Council and staff knew mid-sized cities like ours would also someday be required to maintain stormwater permits. That year, City Council adopted the “Seven Key Outcomes for Stormwater” to set a clear vision for managing stormwater in Springfield.

In 2004, Springfield became the first city in Oregon to receive an NPDES MS4 Phase II stormwater permit from DEQ. Today, Springfield has an exemplary stormwater program providing inspiration and more to similarly sized locales across Oregon and nationwide.

Frequently Asked Questions

Common questions answered:

Why does the City have a stormwater management program?

The City manages stormwater flows across the City to prevent both flooding and pollution. Because municipal runoff from Springfield enters Waters of the State, the City has a permit with the state to discharge this runoff.

Oregon Administrative Rule 603-095-4005 (17) “Waters of This State” means natural waterways, tidal and non-tidal bays, intermittent streams, constantly flowing streams, lakes, wetlands, that portion of the Pacific Ocean that is in the boundaries of this state, all other navigable and non-navigable bodies of water in this state and those portions of the ocean shore, as defined in ORS 390.605 (Definitions), where removal-fill activities are regulated under a state-assumed permit program as provided in 33 U.S.C. 1344(g) of the Federal Water Pollution Control Act, as amended.

Oregon Administrative Rule 603-095-4005 (17) defines “Waters of This State.” This includes rivers, streams, lakes, wetlands, bays, and certain ocean waters within Oregon. It includes both year-round and seasonal waterways. This definition also refers to ORS 390.605 (Definitions) and 33 U.S.C. 1344(g) of the Federal Water Pollution Control Act, which set rules for how water resources are regulated and protected.

Because Springfield’s stormwater drains into these waters, the City must manage stormwater under state and federal law and permit requirements.

Who regulates the City’s stormwater program?

The Oregon Department of Environmental Quality (DEQ) issues and enforces the City’s stormwater permit (Municipal Separate Storm Sewer System or MS4) under the federal Clean Water Act.

What does the stormwater permit require the City to do?

The permit sets required activities, timelines, documentation, and reporting to DEQ.

What does the City control and what is the responsibility of others?

The City plans and maintains the public stormwater system. Property owners are responsible for maintaining the stormwater system on their private property. The City and community members work together to prevent stormwater pollution.

Who pays for stormwater services?

Utility customers pay a monthly stormwater charge on their utility bill. Stormwater services are not paid for with taxes. The charge pays for the stormwater system, which reduces flooding and protects all the streets and structures in Springfield. The stormwater charge can only be used for stormwater-related work.

For this year's stormwater charges:

For the stormwater budget:

What do the stormwater charges fund?

Stormwater fees are necessary to fund Springfield’s federally required stormwater management program, which includes:

  • Cleaning and maintaining 200 miles of stormwater pipelines.
  • Cleaning 6,500 storm drain basins, which keeps 100 tons of sediment and pollutants out of local waterways.
  • Sweeping 6,000 miles of paved streets, removing 1,000 tons of street debris.
  • Collecting 200 tons of leaves through the Leaf Pickup Program.
  • Maintaining stormwater features (includes ditches, ponds, swales, wetlands, etc.)
  • Planting native vegetation and removing invasive species along public waterways, and providing equipment to community groups doing the same.
  • Establishing codes to protect riparian and wetland areas, which improve waterway health.
  • Addressing illegal stormwater pollution.
  • Providing public education to prevent stormwater pollution.

How do I give my opinion on Springfield's stormwater permits and plans?

Springfield stormwater plans and permits are updated every several years. The most effective way to make a change is to participate in the public comment period.

Public comment periods are open only for a limited time, such as 2-weeks, so consider joining a mailing list or contacting the Stormwater Team.

What happens if I report stormwater pollution?

When you see someone is dumping or releasing pollution that may enter the stormwater system, contact the Stormwater Team:

You have the option to be anonymous or, if you provide contact information, we can get back to you about our investigation.

We call stormwater pollution an "Illicit Discharge" and will respond quickly to prevent water it. We also investigate the cause and educate the person causing pollution so it doesn't happen again. The Stormwater Team may also submit a report to Springfield Code Enforcement.

I received a flier at my door. Why?

The Stormwater Team distributes fliers for two main reasons:

  1. To raise awareness of the stormwater system and waterways in your area. Storm drains flow to our valuable water resources – wetlands and waterways. Protecting water quality is everyone's responsibility, so we ask for your help in letting us know if you notice water pollution in your area.
  2. Because we found illegal stormwater pollution coming from your area. By alerting all the neighbors, we remind those who did it that it needs to stop, and ask neighbors to keep an eye out and let us know. Water pollution must not be allowed to continue. It harms public health, water quality, and roughly 280 miles of riverfront from Springfield, to Portland, to the Coast.
