Be Prepared

Take Winter by Storm!

Remember that storms can happen all year long, so be prepared! Be aware that flooding can affect you no matter where you live, but especially if your home is in a low-lying area, near a river or creek, or below street level. Find out all the things you can do to be prepared at Take Winter By Storm.


Keep leaves, debris and snow out of drains

Consider adopting your local storm drains. By keeping the drains in your neighborhood clear of all debris you can prevent flooding. Clear your drain only if it is safe. If the drain is still clogged after you’ve removed the debris, call our drainage problem hotline at (206) 386-1800 to report it.
