Joint SR 530 Landslide Commission

Final Report

SR 530 Landslide Commission Final Report [Released Dec.15, 2014]


Governor Jay Inslee and Snohomish County Executive John Lovick formed a joint commission in response to the SR 530 landslide of March 2014.

The governor and the executive agreed the commission’s operations should:

  • Operate independently from the state and county executive branches
  • Be thoughtful, fair, compassionate and credible
  • Be transparent and abide by open meetings and public records laws
  • Produce a report of prioritized recommendations by Dec. 15, 2014

One of government’s key roles is to promote public safety. The commission will focus its work on identifying recommendations related to the SR 530 landslide that, if implemented today, would improve planning and response for similar events. The commission will not determine liability, cause or fault. Commission members will:

  • Perform a high-level review of the incident and establish a timeline of events. Review of the emergency response to the slide may include the initial emergency search and rescue, recovery of victims, community efforts and coordination among local, county, state, tribal and federal governments.
  • Identify information gaps, lessons learned or technical needs, and proposed changes to policy, code or operational procedures.
