The short answer
Virginia requires most impounding structures to have a current dam-break inundation zone map and an emergency action plan, prepared by a licensed professional engineer and filed with DCR and local emergency officials. The map drives your hazard classification, which in turn drives inspection frequency, permit conditions, and your exposure if a failure ever occurs — so an outdated map is both a compliance problem and a liability problem.
