Living on the coast has its challenges. Everyone knows that sand dunes shift over time, but few expect dramatic movement over just a few days. But that is exactly what happened in the little beach community of Waldport on the Oregon coast. After a series of powerful storms hit the coast in succession, the dunes moved. They enveloped homes, caved in walls, and broke windows. I’ll bet some of the houses in this community were compromised enough to be uninhabitable. The power of sand and wind.
