Areas of Seattle projected by Seattle Public Utilities to be below sea level during high tide
(Mean Higher High Water) and therefore at risk of flooding or inundation are shaded in blue under three levels of sea level
rise,
medium [13 inches] levels are within the range projected for the Northwest by 2100; the highest level [88 inches] includes the
compounding effect of storm surge, derived from the highest observed historical tide in
Seattle
sea level may not be inundated, but could experience problems due to areas of standing water caused by a rise in the water
table and drainage pipes backed up with seawater. (Figure source: Seattle Public
