Esri ArcGIS Online (AGOL) Feature Layer which provides access to the MDOT SHA2015 Mean Sea Level 10% Annual Chance (10-Year Storm) - Flood Depth Griddata product.MDOT SHA2015 Mean Sea Level 10% Annual Chance (10-Year Storm) - Flood Depth Gridconsists of a depth grid image service depicting conditions of sea level change based on the 10% annual chance event (10-Year Storm) scenario for coastal areas throughout the State of Maryland in year 2015. 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 SHA2015 Mean Sea Level 10% Annual Chance (10-Year Storm) - Flood 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, 2015.MDOT SHA2015 Mean Sea Level 10% Annual Chance (10-Year Storm) - Flood Depth Griddata was project-based, and will only be updated on an As-Needed basis where and/or when necessary.For more information related to the data, contact MDOT SHA OPPE Innovative Planning & Performance Division (IPPD):Email:IPPD@mdot.maryland.govFor more information, contact MDOT SHA OIT Enterprise Information Services:Email:GIS@mdot.maryland.gov
