Local Climate & Risk Factors
Norfolk is the most flood-threatened major city on the US East Coast — experiencing 5.7mm/year of combined land subsidence and sea level rise; 'sunny day flooding' (tidal flooding without rain) now occurs 5—10x more frequently than in 1960; major naval station presence creates constant commercial restoration demand; Elizabeth River and its branches flood regularly during both tidal events and storms
Flood-prone areas: Larchmont, Riverview, and Ocean View's lakefront neighborhoods face most frequent nuisance and severe tidal flooding; Downtown Norfolk regularly floods during peak tidal events without any rain
