"A ubiquitous travel trailer is the building typology that’s most resilient to rising sea level. A coastal resident can park her dwelling unit right on the waterfront and then, as the water level rises, simply tow it uphill.To make maximum advantage of the resilience of recreational vehicles, perhaps we should design coastal communities that operate more like long-term campgrounds than permanent cities. But do we really want all of our shoreline cities to look like RV campgrounds?"
