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.

Did You Know?

Lowering the thermostat temperature on winter nights and when no one is home can save money and energy.

Cleaning your dryer filter regularly prevents lint build ups that can reduce airflow resulting in clothes not drying completely.

You can save water when washing smaller loads by selecting the setting for the corresponding water level.
