Geometry Type: esriGeometryPolyline
Description: This polyline layer is the coastal profile line that was used to derive inundation surfaces from. It was manually drawn oriented north to south along the New England coastline beginning in Portland Maine and ending in Eastham Massachusetts. The coastal profile line covers the geographic extent of collected USGS surveyed high water mark and storm sensor data as well as the location of USGS coastal tide gages for stillwater data points. The Storm_Event_Data_Points layer were snapped to the closest location along the coastal profile line and given a stationing measurement. The elevation values were used to calculate a linear relationship between stationing and elevation. The centroids of all coastal HUC12 basins were then snapped to the coastal profile line to derive an elevation value based on stationing for the snapped centroids for each storm event and USGS stillwater data. These HUC12 centroid elevations were joined back to the HUC12 polygon layer to estimate and delineated a water surface elevation inside each HUC12 polygon along the New England coastline.

Name: New_England_Coastal_HUC12_polygons
Display Field: Name
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: These 12-digit Hydrologic Unit (HU12) watershed boundaries were selected from the Watershed Boundary Dataset (WBD) along the New England coastline for the purposes of delineating estimated inundation surfaces inside each HU12 polygon area for the January 4th 2018 storm event, March 2nd-4th 2018 storm event, and the USGS stillwater data derived from coastal tide gages.
The selected HU12 polygons received an estimated water surface elevation in feet above NAVD88 from the Coastal_Profile polyline. This was done by generating centroids for the HU12 polygons and
snapping the centroid points to the closest location along the Coastal_Profile polyline layer. These snapped centroid points were assigned a station measurement value in feet along the Coastal_Profile line. This station value could then be used to derive an estimated Water Surface Elevation (WSE) value in feet above NAVD88 for the January and March 2018 storm events as well as an estimated USGS stillwater elevation. The HUC12 centroids with assigned WSE values were joined back to the HU12 polygon attribute table. The WSE fields for each storm event and USGS stillwater are documented in the metadata for this layer. The WSE fields were used to delineate inundation polygons inside each HU12. This was done by creating a raster surface from the WSE fields and determining where the WSE rasters were greater than or equal to the lidar digital elevation model (DEM). The process produces estimated inundation surface raster data sets that can then be converted to inundation polygon layers for cartographic smoothing and generalization.
