I previously worked at an insurance company some years ago. Back then the company was complaining that flood maps were something like decades out of date, and that was irresponsible to let developers build and sell homes to unsuspecting homeowners who had no reason, or even a way, to know they were in a flood plain.
I suspect nothing has changed in the intervening years.
Don’t know about your area, but in ours its Conservation Authorities who map flood plains. Theirs are pretty well updated from my experience working with them.
