Flood Plain Land Use and Cost

Hi,
My husband and I are trying to buy 66 acres in northeast Texas. Most of the land is on a flood plane and I just got curious as to what other people paid for flood plane land and what they subsequently did with it. We are thinking of growing Pecan trees and of course, he's going to have a few animals and raise hay or other grasses to keep an Agricultural Exemption on the 63 that are in the flood plane. Supremely interested in what you can do with it so how much should we pay since it's not really useful for too much other than it's pretty and keeps an open space for us to play with. The 2.7 acres that are not on the flood plane will have the house, a barn etc. The rest of land is adjacent to those 2.7 acres and there is a creek that runs at the bottom of the hill at the far end of the 63 acres. The house lot is adjacent to the developers in progress houses so we are the last house on the block and it's clear that the rains flow down the rear of the 2.7 acres and across the middle of the 63 acres to the creek below. So dry creek through the middle, and a running creek at the bottom.

I don't know anything about the land prices for land in a floodplain though it seems like it would be less.

Pecan trees will probably do well.

If you have animals it might be wise to give them access to higher land in case of a storm that might cause a flood.

did you buy that land? we have just 5 acres and were being heavily taxed in spite of the fact that 2/3 or our 5 is 100 year flood plain. i tried to appeal, but was told by the assessor's office that we should be happy we have land that's near water... and we should just plan to use it recreationally.

so now we're in similar predicament. we plan to plant fruit and nut trees on the land.
i did a quick look into flood zone type housing to set up as guest houses.

From an Engineering point of view, a 100 year flood cycle is rare.
In Australia we have a town, Lismore that has had 190 floods in its 195 year existence!
Planning use of the land should just entail a few tricks such as
-  having fences with wire on the downstream side of the posts.
- access to high ground for stock
- planning structures to cope
