The Memorial

The Oso Slide Memorial Committee is working with Snohomish County Parks, Recreation and Tourism to build a permanent Memorial at the site of the March 22, 2014 mudslide. The Memorial will honor those who were lost in the event, the survivors, the responders, and the surrounding communities. The families, survivors and responders have been participating in a 3 year long, intensive process with Parks staff to generate ideas and settle on a consensus about approach and general principles.

The current concept has been developed through this process. Parks and the Committee worked with MIG/Portico consultants, who specialize in public memorials to draft the conceptual plan. This plan was brought before the families, responders and community members for feedback and, working with additional civil engineering and architectural firms, Parks has brought this concept to a 30% civil design.

The intent of the Memorial is to pay tribute to the lost, the survivors, the response, the communities, healing and resilience of nature. The Memorial holds importance to the families of the lost and the overall community because it is and will be:

  • A place of peace and healing for all, whether they knew anyone involved or not.

  • A place to show gratitude to local communities and the worldwide response.

  • A community gathering space to honor the victims.

  • Individual Memorial space to personalize and leave messages and mementos.

The Fundraising Committee is seeking to raise $6 million in funds and donations to cover the costs of design, permitting,

and construction in a relatively remote site. At least $1 million will be placed into an endowment for

future maintenance and operation of the Memorial.


Parks and the Committee would like to thank Perteet Inc., Reid Middleton, Minaker Architecture, and Northwest Hydraulic Consultants for their generous professional services donations that has helped us get to 30% design.

On March 22, 2014 at 10:37 am the single deadliest landslide in United States history occurred along SR 530 near Oso, Washington. The slide engulfed an entire community, taking the lives of 43 souls. The Slide Memorial will commemorate and educate about the lives lost, a community destroyed, the first responder's  and rescuer's heroic efforts, the grief and resilience of the survivors, and the geological event itself.
