Esri ArcGIS Online (AGOL) Feature Layer which provides access to the MDOT SHA 2100 Mean Higher High Water 0% Annual Chance (No Storm) - Depth Grid data product.MDOT SHA 2100 Mean Higher High Water 0% Annual Chance (No Storm) - Depth Gridconsists of a depth grid image service depicting the projected conditions of mean higher high water based on the 0% annual chance (No Storm) event 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 Higher High Water 0% Annual Chance (No 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 Higher High Water0% Annual Chance (No Storm) - Depth Grid data is owned by theMDOT SHA Innovative Planning & Performance Division (IPPD). TheEastern Shore Regional GIS Cooperative (ESRGC)is the developer / creator of this data product, and continues to maintain & host the data as apublicly available image service. MDOT SHA 2100 Mean Higher High Water 0% Annual Chance (No Storm) - Depth Grid data is only updated on an As-Needed basis when appropriate funding is available. This data was developed & last updated in October 2019 (10/09/2019).Last Updated: 10/09/2019For additional information, contact MDOT SHA OIT Enterprise Information Services:Email:GIS@mdot.maryland.gov
