Protecting People, Property and Our Environment#
Our stormwater utility was established in 1980 to protect our community from damage due to flooding, pooling, erosion and harmful pollutants.
Stormwater is just that - water from a storm, including rain, hail and snow. Typically, this water is either absorbed into the ground or collects in a body of water. However, when living in an urban area with many non-absorbent surfaces (like rooftops, driveways, sidewalks, parking lots and streets), this water becomes runoff, flowing down gutters, through stormwater inlets and the storm sewer system into our streams, rivers and lakes.
Sediment, nutrients, bacteria, metals, pesticides, and other pollutants are picked up as this water flows through the city. Unlike sanitary sewers that go to a treatment plant, most stormwater is discharged directly to local water bodies.
What We Do#
Flood Safety
Learn how to stay safe and protect your home and property from flood risks.
Stormwater Quality
Stormwater pollution is the number one cause of water pollution in the country. See how we address it and how you can help.
Stream Rehabilitation
Creek and stream rehab establishes stream habitat, improves water quality, stabilizes eroding banks, and improves fish passage.
Master Planning
Stormwater master planning creates a plan and vision for how stormwater management can be implemented in each of our 13 basins.
Stormwater Improvements
An estimated 1,500+ structures have been protected from a 100-year flood event with stromwater improvements.
What's In the Works: Projects and Improvements#
