The state of Washington created the SR 530 Landslide Commission in response to the deadly Oso landslide that occurred in March 2014. The commission recently released its report to help guide policy and improve planning and response with greater awareness of conditions.
The first of 17 recommendations is to support a statewide landslide hazard and risk mapping program. The SR 530 Landslide highlights the need to incorporate landslide hazard, risk and vulnerability assessments into land-use planning and expand and refine geologic and geohazard mapping throughout the state.
The report specifically suggests the use of LiDAR mapping to target hazard areas where risk exists for people and property. The report also suggests prioritizing risk mapping in transportation corridors and where growth has been the greatest.
Washington Governor Jay Inslee replied to the report with an announcement that he would request funding for the statewide hazard mapping effort.
