The U.S. Geological Survey (USGS) New England Water Science Center worked with the Federal Emergency Management Agency to document the floods of January 4, 2018 and March 2-4, 2018, in coastal Massachusetts. USGS conducted a frequency analysis of stillwater elevations at three National Oceanic and Atmospheric Administration coastal gages following the coastal floods of 2018. The data for these analyses for gages in Boston, Massachusetts, Portland, Maine, and Seavey Island, Maine are included in the child item "Data to Support Stillwater Analyses." Stillwater elevations recorded in January 2018 in Boston (9.66 feet in the North American Vertical Datum of 1988, NAVD88) had an annual exceedance probability (AEP) of between 2- and 1-percent [...]

These data layers and inundation-map polygons were produced by the USGS New England Water Science Center for viewing the potential flood-extent impact of the January 4, 2018, and March 2-4, 2018, winter-storm events. Tidal-gaging data were compiled here for the computation of new coastal statistical stillwater elevations from Cape Cod Bay north to the New Hampshire border.
