Actually start worrying when insurance companies start refusing to insure properties there against flooding. Estimating risks is their bread and butter, they will know.
I’ve actually discovered (from the Yale “Financial Markets” MOOC) that US government uses mandatory insurance to get people to move out of areas which are likely to be flooded, etc. USG makes the insurance mandatory, and insurance companies, quite predictably, price just about everyone out. People either pay through the nose or move out.
Edit: reading further into the thread, looks like they already are refusing to insure. Move TF out.
