That’s my home area... although I haven’t lived there in quite awhile. I did live there during the big flood in 1994 and before. I can tell you this: There has been a TON of development around there since that time.
Houses now stand where rice fields used to be. There’s no predicting who will be affected and by how much.
One plus to such flooding is: Fire Ants get WIPED out of large areas... :-) Takes them almost a year to spread back in.
In the 70s and 80s I x-rayed in the chemical plants and oil patch down in there. Alvin, West Columbia, Old Ocean and such.
I know we’re supposed to love all of God’s creatures but I have a special dislike for them fire ants.
