help reading flood zone map
(OP)
In the attached the legend says zone AH has a flood depth of 1' to 3'.
But when I look at the map, I can't find zone AH.
I only see Zone AE (base flood elevation determined).
Zone AE does not show high the flood is.
This confuse me because almost all the maps I look at only has Zone AE.
How do I correctly read this map.

RE: help reading flood zone map
Zone AE has base flood elevations determined, so it does show how high the flood is. for instance the Houston ship channel is clearly at a flood stage of 18 feet. I don't believe there are any Zone AH "ponding areas with a depth of 1 - 3 feet" shown on this map or any other types of flood zones.
RE: help reading flood zone map
on the attached I see the 18' you were saying but right next to it is wingate and mobile street that does not have flood elevation.
if I have small equipment in that area, I don't have to raise the foundation (except for the standard 6" above grade).
thanks,
RE: help reading flood zone map
I do a lot of foundation equipment for small stations in many places and want to make sure I account for flood level,
like raising the foundation top of concrete above flood level.
is this fema map the resource I should look at or are there other map I should look at?
thanks,

RE: help reading flood zone map
going to site is not an option most of the time. besides that looks unreliable checking for flood signs.
RE: help reading flood zone map
If you cannot go out to the site and look around, or have it surveyed, than you should be very conservative in your design. It may be unreliable, but sitting at your desk and not gathering any field information is more unreliable.

I have done a dozen of more site grading and none of those I was required to submit or prepare documents for permit.
Most of the sites I do are in open space in the middle of nowhere.
