Tidal_Benchmarks_North_2030

Standardized data sets produced from the Massachusetts Coast Flood Risk Model (MC-FRM) include annual exceedance probability (AEP) ARC-GIS based rasters across all modeled climate time horizons, and depth of flooding at three AEP levels across all modeled climate time horizons (present day, 2030, 2050, and 2070). However, additional non-standardized datasets were requested by the Massachusetts Executive Office of Energy and Environmental Affairs (EEA) to be utilized in the development of climate resiliency tools for the State of Massachusetts. These datasets were produced using the same probabilistic modeling framework created and utilized for the original MC-FRM and Boston Harbor Flood Risk Model (BH-FRM) datasets. These new non-standardized data consist of (1) Water Surface Elevations, (2) Maximum Wave Heights, and (3) calculations of Design Flood Elevations (DFEs). These were determined for six (6) selected annual exceedance probabilities (AEPs) and three (3) time horizons. Additionally, EEA also requested (4) development of Tidal Benchmarks across the state for 2030, 2050, and 2070 projected future sea level rise conditions. For these requested outputs, Woods Hole Group created a set of geographic data features and raster datasets. These datasets were calculated directly from the MC-FRM model simulation results but required additional calculation and processing efforts to create the required GIS based outputs. The GIS outputs (GIS shapefiles and raster files) created for this task are described below.
