Mapping Current and Future Nuisance Flooding Inundation
The notion of nuisance tidal flooding, also known as sunny-day flooding, as a current threat to transportation infrastructure has become better understood. In most coastal locations, these abnormally high tides have traditionally occurred a few times per year, degrading road support facilities and causing traffic congestion. However, NOAA has documented that nuisance flooding has become significantly more common in the Chesapeake Bay watershed. In time, nuisance flooding is expected to become even more frequent and more hazardous as the area experiences sea-level change. Currently, there is no known map of areas prone to nuisance flooding.
