Storm susrge map interpretation confusion

[kenmogul23]

I'm in Naples, FL near the interstate and this app says I am 14 feet above sea level. http://goo.gl/ntnR9rNow if I look at the worst case scenario storm surge maps, it says I am in a zone where I can expect up to ten feet. http://www.nhc.noaa.gov/nationalsurge/ So does that mean that I am OK because I am at 14 feet and therefore a ten foot surge won't get to me. Or does the map mean that I can expect to experience 10 feet of water on top of where I am at 14 feet above sea level? In other words when I look at the NOAA SLOSH map and it says I am in a ten foot zone, does that take into account the fact that I am at 14 foot sea level?

SLOSH uses NGVD (Sea Level) but the Potential Storm Surge maps use ground level.

Collier County seems to handle evacuations differently and doesn’t use the Zone system. Instead they have a wide area shown on this map as potentially impacted by even a Category 2 storm surge. According to this map, if you live in the gray area the county recommends you seek shelter.
