[quote=Anonymous][quote=Anonymous]Ashville is 2,134 feet above sea level. Fairfax county is 300 feet above sea level. So yes, it could happen here.[/quote] Sea level isn't relevant to Asheville: the issue was rain not ocean. We don't have the slope here for the kind of mudslides and rushing water that carried away homes in NC, and we don't have a constrained valley floor for the water to fill up. Coastal Florida is a better geographic comparison. One thing to keep in mind is that paved surfaces worsen runoff and water management problems, because they concentrate water flow into narrow spaces and reduce the absorbent surfaces. This leads to dangerous fast-flowing water and flooding after storms. People hand-wave that as an "environmental" issue, but it's also a safety issue. When your local development boards are greenlighting a new building or road, speak up about runoff. [/quote]
