ArcGIS Online (AGOL) Feature Layer which includes theMDOT SHA 2100 Mean Sea Level 2% Annual Chance (50YR Storm) - Depth Gridgeospatial data product.MDOT SHA 2100 Mean Sea Level 2% Annual Chance (50YR Storm) - Depth Grid consists of a depth grid image service depicting conditions of sea level change based on the 2% annual chance event (50-Year Storm) scenario for coastal areas throughout the State of Maryland in year 2100. 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 2100 Mean Sea Level 2% Annual Chance (50YR Storm) - Depth Griddata 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), NationalOceanic & Atmospheric Administration (NOAA), and the United States Geological Survey (USGS). TheUS Army Corps of Engineers provide the sea level change estimate. Sea level changeis 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 ansea level changevalue for the official project year, 2100.MDOT SHA 2100 Mean Sea Level 2% Annual Chance (50YR Storm) - Depth Griddata was task-based, and will only be updated on an As-Needed basis where necessary.Last Updated: 10/09/2019For additional information, contact the MDOT SHA Geospatial Technologies:Email:GIS@mdot.maryland.govFor information related to the data, visit the Eastern Shore Regional GIS Cooperative (ESRGC) websiteWebsite:https:www.esrgc.org/mapServices/For additional data, visit the MDOT GIS Open Data Portal:Website:https://data.imap.maryland.gov/pages/mdot/For additional information related to the Maryland Department of Transportation (MDOT):Website:https://www.mdot.maryland.gov/For additional information related to the Maryland Department of Transportation State Highway Administration (MDOT SHA):Website:https://www.roads.maryland.gov/Home.aspxMDOT SHA Geospatial Data Legal Disclaimer:The Maryland Department of Transportation State Highway Administration (MDOT SHA) makes no warranty, expressed or implied, as to the use or appropriateness of geospatial data, and there are no warranties of merchantability or fitness for a particular purpose or use.
