Landslides on Mercer Island

MI Landslide Example

Shortcut to this page:

To report a landslide, call our regional, non-emergency dispatch center (425) 577-5656, open 24 hours a day, 7 days a week...

As soon as the City learns of such an event, the City's lead Building Official travels directly to the affected site to assess the damage firsthand, and determine whether the buildings involved are still safe for occupancy.  Unsafe buildings are "red-tagged" and may not be occupied until cleared by a geo-technical engineer, hired by the owner.  You can help by making sure storm drains are clear in your neighborhood to help rain water flow away.
