Five weeks after the Oso mudslide, the recovery effort is winding down. Deferred questions await, and new priorities arise: What caused this unexpectedly big disaster on March 22, and did humans play a role? How do we restore crucial state Highway 530? What economic help is available? These and other issues are addressed by hundreds of pages of documents and dozens of websites that have emerged in recent weeks. As our communities work to recover from the most deadly disaster in Snohomish County history, we offer this selected list of major resources. We’ll update this online as things develop.
