July 2, 2016

King County Superior Court Judge Roger Rogoff held that only those who attended a 2006 meeting about flooding and other hazard risks in the Steelhead Haven area or “who relied on the substance” of information shared at that meeting, could press claims that they were insufficiently warned. In 2006, Highway 530 sank six inches in February of that year between Arlington and Darrington. A Herald story at the time titled “Slump in hill may isolate Darrington” stated, “The fear of a big slide was underscored by the massive collapse two weeks ago of a hillside just a mile away that blocked and diverted the Stillaguamish River.” Eight years later, that was exactly what happened.
