The FEMA elevation certification uses collected data from the field and cross-examines it with the Flood Insurance Rate Map (FIRM) to determine if flood insurance is required for a given property. The collected data has to do with the property location on the FIRM, as well as the elevation of the house and adjacent ground level.
The FIRM shows the 100-year flood location and the AE zones along with their 100-year flood values. Areas in the AE zone are areas that have a 1% probability of flooding every year. The FEMA elevation certification can be used for residential and commercial properties.
