Figure 11. Table summarizing the frequency that flood stage (12 feet MLLW) was met or exceeded based on 2011 data from the Portland, ME tidal station using the NOAA CO-OPS Inundation Analysis Tool. For each scenario, sea level rise was added to determine the changes in flood frequency, based on using 2011 data as a proxy for an "average" year. Data courtesy of NOAA's Tides & Currents website.
