[ARCHIVED] Update: Northwest Talus Drive

Hillside movement was recently observed near Northwest Talus Drive and Shangri-La Way Northwest at Parcel 9.

The movement has now appeared to stop, and crews are continuing to monitor the situation. There is no immediate safety concern.

All construction activities have stopped, except for work to monitor the site, ensure safety and collect data to determine next steps. This work could continue for the next several weeks.

So far, that work includes:

  • Installing a temporary buttress at the base of the hillside on Nov. 13.
  • Installing monitors for data collection.
  • Reviews by geotechnical engineers (from both the developer and the City of Issaquah). Based on observations so far, it appears that there has not been new movement since Nov. 13.
  • Temporary Erosion and Sediment Controls (TESC) are being monitored and enhanced, as needed. TESC is a requirement of nearly every construction project.

As a next step, crews plan to dewater the site. Wells will be drilled and pumping may lead to some generator noise in the evenings.
