Storm System Overview

The Public Works Department maintains 85 miles of storm sewer throughout the City. This includes the inspection, cleaning and maintenance of more than 5,000 stormwater structures (manholes, catch basins and catch basin sumps).

How You Can Help

If you live near a storm drain, check to make sure it is clear of leaves and other debris, including snow and ice during the winter months. Flooding may occur during periods of heavy rain or rapid snow melt if the drains are blocked by debris, preventing the normal discharge of stormwater into the system. Clogged storm drains can also have a significant negative impact on local water bodies.  Watch this short video from Kare 11 News for more information on this issue.  Your help is appreciated!

If you see illegal dumping of oil, gasoline, paint or other chemicals into the storm drains, please contact the Public Works department at 651-322-2022.
