[ARCHIVED] Wet Weather: Flood Preparation


With heavy rain in the area, now is the time to take steps to prepare for wet weather and potential flooding.


See if you are in a flood-prone area based on previous experience (talk to your neighbors) or check our floodplain maps. Become familiar with the Issaquah Flood Warning System

If the City were to reach a significant flood phase, information will be posted via social media, radio station 1700 AM and our website.

Review what you need to do before, during and after a flood. Make sure all family members know the emergency phone numbers. Learn the safest route from your home or business to safe, high ground. Set up your own neighborhood notification network. Keep a portable radio, emergency cooking equipment, flashlights, fresh batteries, non-perishable food and drinking water on hand.

Work with Neighbors

Work with neighbors and share information on preparedness and previous experiences.

Prepare to Minimize Damage

Store valuables at a higher elevation (second story if possible). Store household chemicals above flood levels. Ensure that underground storage tanks are fully secure. Install flood drain plugs and septic backflow valves to prevent backflow of water into your home.

Purchase flood insurance to protect your structure and possessions from flood damage losses. Homeowners insurance typically doesn't cover flood loss.

If your home has a history of flooding, be prepared to place sandbags around your home. If needed, request free sand and bags from the City of Issaquah. For more information, call 425-837-3470. Consider long-term measures to reduce flooding impacts, such as flood-proofing and elevating your house.

Prevent Flooding

To prevent any localized flooding, residents can help out by keeping the storm drains near their homes clear of debris and leaves. 

For larger storm water issues, call the City of Issaquah’s Public Works Operations Department at 425-837-3470.
