Our pilings are about 21 ft above low water. Our HW can be 16 feet

So if there was a storm surge that cause the water to rise 9 feet above
normal
high tide, what would happen? Thank you.

Last year we had a F9 which didn't cause a problem in the marinas.

AFAIK, the biggest storm that has hit us was in 1989. IIRC, only one marina
had a pontoon float free of it's pilings.

Here in Apalachee bay (NE corner of Gulf of Mexico), predicted storm
surges for a category 4 hurricane is over 20 feet. In the 1800s there
was apparently at least one hurricane here with such a surge. I have
read there are indications of storm surges as high as 25 feet before
1600. A category 5 could easily produce a surge in excess of 25' due
to the very shallow water here.
Oddly, there are many houses built on the ground and even many mobile
homes that have been here for 40 years. This just means that the
surge area is limited and large surges do not occur often. However,
even the march 1993 Storm of the Century caused a 15' surge at
Steinhatchee and that was only about a category 2 level.
