SR 530 Mudslide Memorial

Snohomish County Parks, Recreation and Tourism has been working with families of victims and survivors of the March 22, 2014 SR 530 Mudslide to develop a concept and initial design for a memorial to those who were lost, as well as the Steelhead Drive and C-Post neighborhoods that were devastated by the event. Tributes to the Community lost, the First Responders and the Community Response will also be included as elements of the Memorial.

This page is dedicated to project updates and documents, and will be updated regularly, as the design is developed.

Design Concept



Parks has held five meetings with the families of victims, 3 meetings with survivors and one meeting with first responders and community responders. The following concept has been derived from those meetings. An additional concept refinement has been developed by MIG/Portico, a local interpretive design consulting team that adds therapeutic design elements to the concept. Parks will continue meeting with families, survivors, responders and volunteers to further refine the design and develop content for the Memorial.

​Project Funding

Parks staff estimates the total cost of the SR 530 Mudslide Memorial to come in between $1 - 2 Million and has set aside seed money to complete the necessary studies, design and engineering of the site. Additional improvements include installing a low barrier along the Whitehorse Regional Trail to discourage trail users and Memorial visitors from accessing the mudslide area. Parks is also working with a structural engineering team from Chudgar Engineering to preserve the First Responder flag pole and build a permanent foundation for it.

Donations for materials, services or funds can be accepted through the Snohomish County Parks Donation Fund. All proceeds collected for the SR 530 Mudslide Memorial will be 100 percent dedicated to the project. Please contact one of the staff members below for additional information about donations.
