kelly do you know of any site online where potential flooding events could be mapped based on rain amount/water table? i’ve looked at floodplain maps but i don’t know how to ask “if that happened here, where would we be?” scenario.

The... annoying answer to this is that rain amounts don't map especially cleanly to flood amounts. The same amount of rain can do nothing if it comes after a drought, and a huge flood if the ground is already saturated.
