The goal of water management is to keep the water out of the houses, it needs to go someplace, it will go to the golf courses, the tunnels, etc.
My understanding is that very few homes had water intrusion with Irma.

You are correct with the addition that a 100 year storm means that there is a 1% chance of it happening "in a given year". It should be noted that Ian was a 1000 year storm meaning there was a 1/10 of a percent chance of it happening in a given year. It's an also be noted that so far in the United States there has been
five 1000 year storms. So much for statistics.
