I wish we would stop referring to cabins in the 100 year floodzone. Yes, some indeed were in the 100 year flood zone but the lowest ones were in the floodway. There is a difference.
Let me show you a non-Mystic example or two...
Here is Buffalo Bayou in Houston close to BW8/T&C and as you go into the villages... the flood zone is light blue. You build/live there, you need insurance and assume there is a risk because you are in the 100 year flood plain. The green is the 500 year flood plain. Lower risk, no flood insurance required. The dark blue... yeah, that shit is flooding. When we flooded with Harvey, our neighborhood had a house built around 1958 in the floodway. That house got wrecked. You do not build in the floodway. THAT is where Mystic had cabins full of little girls.
Now here's Meyerland. Damn they won't stop rebuilding houses in the flood zone... you've probably seen the crazy ass lifted homes on Braeswood before. Flood zone. Yeah, I think they're kind of dumb. Meyerland farts and it floods. BUT they're not in the floodway. That's insane. That's where Mystic knowingly maintaned cabins.
Now, back to the Mystic map...
A or light blue is the flood zone... like the people who lift their houses in Meyerland. The striped section is floodway, like the dark blue above and where Mystic had the youngest children.
Different view...
