Esri ArcGIS Online (AGOL) Imagery Layer for accessing theMaryland 2050 Nuisance Tidal Inundation - Flood Depth Grid.Maryland 2050 Nuisance Tidal Inundation - Flood Depth Grid consists of an image service showing geographic areas throughout the State of Maryland that are projected to be impacted by a nuisance tidal flooding scenario in year 2050.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.Maryland 2050 Nuisance Tidal Inundation - Flood Depth Grid datarepresents projected stillwater depths (ft) during a 'nuisance' tidal flooding scenario. This data is an attempt to aid in identifying potential vulnerabilities along Maryland's roadway infrastructure. The data supports MDOT State Highway Administration leadership and planners as they endeavor to mitigate or prevent the impacts of sea level change resulting from land surface subsidence and rising sea levels. The product uses sea-level projections to forecasts areas of inundation for a given scenario. University of Maryland Center for Environmental Science (UMCES) provides the sea level change (SLC) estimate. SLC is localized using qualifying National Oceanic and Atmospheric Administration (NOAA) tidal reference stations.The data may be used and redistributed for free but is not intended for legal use, since it likely contains inaccuracies.
