"At Lewes, relative sea level is rising at a rate of about 3.16 millimeters a year — equal to the height of three stacked pennies. "
This adds up to about a foot a century.
This is important because it has been centuries since the area recieved major flooding.
This creeping of water effect may add to the problems of a storm surge if a hurricane hits.
Storm surge is temporary but the yearly sea level rise is not!

Sussex county doesn't appear to be the worst spot for storm surge in Delaware.
Reguardless, if the storm surge hit 15 feet, which seems possible, then an evacuation of upto a mile
inland may be necessary in some places.
Also, many cities in Sussex county are located along the coast which adds to the problem.

Andreas: Excellent work, Chris. I would not worry about the 3 pennies, even when stacked up at that annual rate for 10 years. But what else should I worry that may add or subtract from the storm surge? Also, how are those predictions made? And how do past prediction of (much weaker) storms compare with observations?
