The low-lying Del Marva peninsula, shared by portions of Maryland, Delaware, and Virginia, gets floods during heavy rains. But that’s nothing compared to the impact of a 100-year storm surge, according to FEMA. The agency’s newest floodplain maps for the region add many new properties to the flood zone. The one-two punch of expanded flood zones and spiking premiums “could be devastating” for some property owners, reports the Del Marva Now news website (“New FEMA flood maps, premium hike, may hit county residents hard,” by Debra Gates).
