Landslide Risk Continues on Mercer Island
Feb 20, 2017 - With the heavy rains last week, the City witnessed at least six significant landslides around the Island, affecting access to over a dozen houses as well some natural area trails.
With more rain in the forecast for the beginning of this week, landslide potential is still high due to saturated soils, and data gathered by the USGS underscores this risk.
As is customary in these situations, as soon as the City learns of such an event, the 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.

Residents can also make sure storm drains are clear in their neighborhood to help water flow away.
For emergencies, call 9-1-1.
