what are the issues building in a flood zone?

I've found a very nice piece of property that is divided by creek, About 1.5 acres on either side. Its obvious the property floods regularly; probably once a year or so. Are there generally restriction on what I do to the property as in adding a retaining wall to build up the land?

Insurance will be more. It you do anything to lower your flood risk it must meet certain legal requirements. Ie you can't just build a levee and call it good. It must be engineered
Is it classified as a wetland?

I don't know if it's classified wetlands. My guess is that it likely is otherwise someone would have already made improvements. Are wetlands generally no go zones?

You'll have to mitigate on a habitat value basis if it's a wetland likely

Appreciate any feedback. The area I'm looking at is in the gray area of the map linked above labeled as "other flood areas". It also encompasses areas described as a "floodway areas in zone AE." Am i reading this correctly that I basically just need to prevent my home acting like a damn during flooding? Obviously I need everything permitted and approved but just wondering what it would take to build in this area

An engineer or local real estate agent can help you answer this Q.

You may be required by local code to build at base flood plus a certain number of feet, depending on the flood height risk in the zone. If the area is classified as an actual flood way, be prepared for 12+ feet or more.

The map there is TX, so I can't give a whole lot of valuable insight.
If that were say, Livingston parish, and the gray area was only around that drainage I would say that wasn't bad at all. Here both sides of a drainage canal are flood zones for so many feet, but on that map the rest looks pretty good. A surveyor should be your first stop to give you an elevation so u will know if you are looking at going up 1 ft or 10 ft.

you're going to need talk to the local building permit office for details. Generally you can build in the AE zone, but have to build to a specified level above the expected flood level. Could be a few feet, could be 20'. The numbers in the zone are the flood levels above sea level. The land may be 125', flood level is 135', so you'd have to build 10' plus whatever the local ordinance requires. The notes on the right suggest you can't restrict flow by adding fill or a retaining wall, but again, you'll need to talk to the local inspector for details.
