The city of South Portland is among the first communities in southern Maine to create detailed maps that show what flooding due to sea level rise will look like in the coming decades. The maps use state sea level rise data, but reveal in more detail down to individual streets and properties, what will be impacted with a projected 3.9 feet of sea level rise. They show that seven neighborhoods will be particularly vulnerable to flooding during three broad scenarios — daily high tides, the occasional astronomical, or "king" tide, and major storms — within the next 25 to 75 years.
