Catch Basin (also known as storm drain) maintenance
In some areas, inlet control devices are installed in the drains by the City or developers to control how fast water flows.
These devices prevent the storm system from causing water backups, flooding to houses/garages/businesses, and to protect the system from construction debris.
The flooding on your street will eventually drain once the storm system accepts the excess water - this can take up to 2 hours after rainfall has ended.
If it’s safe and possible to do, you may clear debris, ice and/or snow that’s blocking your storm drain to help water flow. Do not attempt to clean a catch basin if it’s submerged in water. You cannot be sure if the grate is intact, presenting a safety risk.
If water still completely covers the catch basin 2 hours after rainfall has ended - please email or call Community Operations at 403-207-2807.
