We are pleased to publish the results of the 2017–2019 School Seismic Safety Project

The School Seismic Safety Project (SSSP) is the first phase of a statewide effort to systematically evaluate Washington school buildings for seismic performance. Many of Washington’s K–12 students attend schools that may not withstand earthquake shaking. Washington State ranks second in the nation for earthquake risk, and most of Washington’s public school buildings were built before the adoption of modern building codes. The results of the SSSP will inform schools, districts, and public officials of the policy and funding needs for improving the seismic safety of our state’s K–12 public school buildings.

The final report for the SSSP gives an overview of the project, presents the main results of the study, and suggests directions for further work. You can download the report here.

The results of the soil seismic site class assessments conducted as part of the SSSP are also available as a new publication, which you can download here.
