Parent Layer: Maximum Water Building Footprints

Display Field: BLD_NAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: The layer supports Maryland Department of Natural Resources (MDDNR) 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 forecast maximum stillwater elevations and first floor flooding inside building footprints of Somerset County's for a given scenario.Methodology:US Army Corps of Engineers (USACE) provide the sea level change (SLC) estimate-1. SLC is localized using water elevations collected from a qualifying-2 National Oceanic and Atmospheric Administration (NOAA) tidal reference station - NOAA observations are transformed from tidal datum to North American Vertical Datum of 1988 (NAVD88). A final correction for glacial isostatic adjustment and land subsidence is applied to create an SLC value for the official project year, 2015.Forecast Sea Level Change:Year; Tide: SLC Value; Tide: SLC Value2015; MSL: 0; MHHW: 1.022020; MSL: 0.52; MHHW: 1.542030; MSL: 0.88; MHHW: 1.902040; MSL: 1.31; MHHW: 2.332050; MSL: 1.82; MHHW: 2.84The best available LiDAR, at time of creation, contributes to a county-wide Digital Elevation Model (DEM). The LiDAR-derived DEM is the base from which the SLC value is applied.The SLC adjusted DEM serves as elevation data for a Level 1 Coastal Only HAZUS-MH (FEMA) Flood analysis. The shoreline of the county level study is limited to Deal Island Neck.

An average or qualifying stations was chosen when the nearest station’s records were insufficient.
