Get to the hearings and make noise. We have no business building in flood zones no matter what in my opinion. The systems in place are bought and paid for politically by MONEY ! The squeaky wheel gets consideration. Be vocal. Study the land use codes. Use the appeals system to fight for what you believe in. By all means do this. It is rewarding and the right thing to do. I have opposed development many times if it did not make sense. You can not stop it but you can change the outcome for the better!
Good question. Let me know what you do if anything!
