Max storm surge reading

[zboss]

Folks,

I am trying to determine what can be expected at my marina during a storm surge. I found the following web page but I cannot determine exactly what is meant by "maximum elevation in feet". Above what? Mean low water?

Storm surge projections | StAugustine.com

Above theoretical current tide level at the time of the surge?

Edit:
Just googled to be sure.
According to NOAA:
"Storm surge is an abnormal rise of water generated by a storm, over and above the predicted astronomical tide.
It's the change in the water level that is due to the presence of the storm
Since storm surge is difference between water levels it does not have a reference level "

Then I wonder why they use an unconventional description? This makes no sense and its maybe an engineering company that does not follow NOAA standards did the survey.

It makes it very difficult to understand... they should have included some examples.

The Florida Dept. of Community Affairs does extensive storm surge modeling that is used in evaluating development risk based on probable storm surge. They use worst case conditions (high tide springs) for each category of hurricane (1-5) and then establish a land surface elevation (above MSL) that will likely be inundated. There's more than just the elevation taken into account, but that is the first cut, and based on the crappy presentation and the cited source I would presume that is where those elevations come from.

You might find this map (based on the same data) of interest:

Thanks you! Much more what I was looking for!
