 Tracy Campbell - Stormwater Superintendent

Tracy Campbell is the Superintendent of the City of Missoula Stormwater Utility and has worked with the City since 2019. She started as a Program Specialist and was promoted less than one year after she was hired. Tracy manages the operations and maintenance of the City's flood control facilities: 5,000 dry wells, 42 outfalls, 43 miles of pipes, and 14,000 linear feet of levees. She is also responsible for compliance with the Municipal Separate Storm Sewer System (MS4) Permit, which is administered by the Montana Department of Environmental Quality under the authority of the U.S. Environmental Protection Agency. Most of the City's stormwater runoff is discharged directly to our aquifer and waterways without any treatment. As stormwater flows across developed areas, it picks up and carries away pollutants, depositing them into creeks, rivers, and groundwater. This is the number one cause of water quality issues in Montana. Tracy is working on implementing projects and revising standards that will improve how the City manages stormwater.

Ms. Campbell has nearly 20 years of experience in environmental regulatory compliance, specializing in the Clean Water Act, USACE Levee Safety Program, and floodplain management. She received her Bachelor of Science from Colorado State University and her Master of Science from Montana State University. She is committed to applying scientific principles to protect water quality, helping the City of Missoula make meaningful progress towards environmental sustainability and climate resiliency.

Marie Nelson - Program Specialist

Marie Nelson is the Program Specialist for the City of Missoula Stormwater Utility. Since 2019, she has served multiple roles—from marketing, design, public outreach, and staff training, to coordinating emergency repairs and routine maintenance on our vast stormwater infrastructure.  

Currently, Ms. Nelson is focused on improving public awareness about community impact on local water quality, per the City’s MS4 Permit requirements.  Education and awareness are critical, to protect our waterways  from pollutants generated due to increased urbanization and unprecedented growth. Through public ads, community cleanups, collaborating with local non-profits, neighborhood council meetings, and teaching students about pollution prevention– the Stormwater message about water quality is growing every day.

With over 25 years in marketing and customer service, and over a decade of practical experience in flood-related fieldwork throughout the Missoula Valley, Ms. Nelson has found her purpose in the Stormwater Utility.  She has a passion for education and the environment and brings that excitement to share with all of Missoula.

Maxine Winslow  - Program Coordinator

Prior to starting as the Program Coordinator for the City of Missoula Stormwater Utility, Maxine graduated with honors from Washington State University with a Bachelor of Science in Environmental and Ecosystem Sciences emphasizing in natural resource ecology and water science. While attending university, she worked as an intern with the Kitsap County Stormwater Division located in Western Washington. Within her role as Program Coordinator, Maxine will be coordinating with the public to ensure that our stormwater infrastructure is functioning correctly so that stormwater is properly drained from our sidewalks and streets. Her other tasks include locating geographic data on infrastructure, grant management, public outreach, and assisting in the Stormwater Utility’s water sampling plan. 

Carver Butterfield - Operations and Maintenance Manager

Carver Butterfield began his work with the Missoula Stormwater Utility in 2020 as an AmeriCorps Conservation Fellow. Following his 6-month term of service, he was hired as a Program Coordinator, where he focused on GIS data reconciliation, water quality sampling, and stormwater pollution prevention.

In Fall 2022, Carver began a master's program at the University of Montana, where his research centered on the impact of urbanization on the Pattee Creek Watershed. After completing his degree, Carver returned to the Stormwater Utility as the Operations and Maintenance Manager. In this role, he oversees the installation, maintenance, and repair of Missoula's stormwater infrastructure. He is also responsible for inspecting, testing, and collecting data to evaluate the safety, effectiveness, and long-term viability of that infrastructure.

Carver's goal is to foster a healthier relationship between humans and hydrology in Missoula. He is committed to sustainable practices that enhance both community resilience and watershed health.
