Most of the general public (69%) doesn’t believe that they are at risk of flooding, though most (68%) local official know many are wrong to feel so safe. The public wants to hear about flood risk from municipal/county officials (47% want the mayor, 32% the floodplain manager)—unfortunately, nearly half (45%) report that they “never” do. As for methods to reach the public, almost everybody (87%) wants it via local news.
