Helping to Keep our Flood Insurance Rates Down


The purpose of this page is to inform our community about our historical flooding events and our warning and response systems in place.  This page also serves as a one-stop spot for us to maximize getting points to reduce our community's flood insurance costs.

Background Information:

 - Hurricane Donna Surge (1960) - In 1960, the population in Collier County was about 15,000.  Most of the people resided on the coastline and in the farming community of Immokalee.

 - The whole Hurricane Donna Impact  - This document gives you the detailed story about Hurricane Donna.

 - Hurricane Wilma Surge (2005) - The greatest impact to Collier County was felt near Everglades City.  This map shows the surge values from that storm.

 - Community Nuisance Flooding Map This map represents nuisance flooding, mainly on the roadways.  Such flooding may also affect the wells and septic systems.  Not all areas on the map have the flooding indicated for every event.  The flooded areas are dependent on the storm, how saturated our grounds are that would prevent percolation, etc.

 - Collier County Storm Surge Inundation Map -  If you live in the shaded area indicated on the map, you should have a plan to evacuate, should the order be given.  This map shows shelter locations as well as evacuation routes.
