Flood Awareness Information:

Helping the citizens of Sorrento learn how to prepare for emergencies is a priority. The Ascension Parish Office of Homeland Security and Emergency Preparedness (AP OHSEP) has produced the all-hazards preparedness guide to generate public awareness and encourage you to develop your own readiness for your family. We hope this guide will help prepare you and your family to be ready in case of a major disaster.  Being prepared for an emergency can reduce the possibility of personal injury, loss of life and damage to property. Know your flood warnings signals, create an emergency plan, and prepare a disaster supply kit. To find out more information on flood warnings and emergency preparedness; contact your local Emergency Preparedness office or see below for more flood awareness information.

Ascension Parish FlRM Maps:

In order to help determine the flooding risk of properties in a particular area, FEMA has developed a series of maps for Ascension Parish showing “flood zone” areas.  Technically, these are areas estimated to have a one percent probability of being inundated by floodwaters in any given year.  This is also commonly called the hundred-year flood.

The below link will take you to scans of the official FEMA Flood Insurance Rate Maps where you can see if your property is in a shaded flood zone area or not. The Parish of Ascension also offers several unofficial online maps that can help you determine your Floodzone and elevation on their Online Maps Gallery.

Previously issued LOMCs that were revalidated with the issuance of the August 17, 2007 National Flood Insurance Rate Maps.

I received a letter from my mortgage company informing me that I am now in the flood zone and will need to obtain flood insurance.  I was not in the flood zone before.  What do I do?

FEMA has a Grandfathering Rule to provide a reduced rate for homeowners that were not in a flood zone prior to the issuance of new flood maps, and therefore, never obtained flood insurance.  In order to apply for the grandfathering provision you will need to provide your insurance company with a Compliance Letter stating that your structure was built in compliance with the flood maps at the time of construction.
