ArcGIS Online for MarylandEsri ArcGIS Online (AGOL) Imagery Layer which includes the MDOT SHA 2050 Mean Sea Level 0% Annual Chance (No Storm) - Flood Depth Grid data product. MDOT SHA 2050 Mean Sea Level 0% Annual Chance (No Storm) - Flood Depth Grid consists of a depth grid image service depicting mean sea level with still-water conditions based on the 0% annual chance (No Storm) event for coastal areas throughout the State of Maryland in year 2050. This data product supports Maryland Department of Transportation State Highway Administration (MDOT SHA) 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. MDOT SHA 2050 Mean Sea Level 0% Annual Chance (No Storm) - Flood Depth Grid data was produced as a result of efforts by the Maryland Department of Transportation State Highway Administration (MDOT SHA), Eastern Shore Regional GIS Cooperative (ESRGC), Salisbury University (SU), United States Corps of Engineers (USACE), National Oceanic & Atmospheric Administration (NOAA), and the United States Geological Survey (USGS). The US Army Corps of Engineers provide the sea level change estimate. Sea level change is localized using water elevations collected from a qualifying National Oceanic and Atmospheric Administration (NOAA) tidal reference station - NOAA observations are transformed from tidal datum to North American Vertical Datum of 1988. A final correction for glacial isostatic adjustment and land creates an sea level change value for the official project year, 2050. MDOT SHA 2050 Mean Sea Level 0% Annual Chance (No Storm) - Flood Depth Grid data was task-based, and will only be updated on an As-Needed basis where necessary.
