Thanks to Irma, I got two days off this week to work on our house, which flooded a bit, and our backyard, which may have been at least partly to blame. At least, that’s what the experts in my circle of acquaintances think, and they convinced my wife, who convinced me. The experts said we can prevent more flooding the next big storm with some changes to the way our backyard is sloped and shaped, or maybe it was shaped and sloped.
