Zone A, AE, and AH – The top of the lowest occupiable floor must be at or above the minimum elevation required by the Sarasota County Floodprone Areas Ordinance. What are the elevation requirements for new construction and substantial improvements to existing structures in flood zones shown on the Sarasota County preliminary FIRMs? Even though flood insurance Is not mandatory it is still recommended as all properties in the county have some element of flood risk. Flood insurance will be optional at the lower Preferred Risk Policy (PRP) rate after the new map becomes effective.If the preliminary map shows the property that is currently in the SFHA is changing to a Zone X or X500 Mandatory purchase requirement only applies if the house has a federally backed mortgage. When the preliminary maps become effective the insurance company may request a new FEMA Elevation Certificate. Continue buying flood insurance and check with an insurance agent to see if changes in BFE or zone designation affect the insurance rate.If the preliminary map shows a property in the SFHA is changing to a different designation within the SFHA (like A to AO) Renters may buy flood insurance for contents, regardless of the property owner's flood insurance status. Property owners without a federally backed mortgage may still opt to purchase flood insurance.

Purchasing insurance before the change takes effect delays the applicability of full standard-rate policy premiums. All property owners with a federally backed mortgage in a SFHA are required to purchase flood insurance.Property owners with a federally backed mortgage can save money by purchasing flood insurance before the preliminary FIRM is adopted.If the property is changing from Zone X or X500 to a SFHA (Zone VE, A, AE, AH, CAZ or AO) Flood insurance is available in these areas but is not required by regulation in these zones. However, buildings in these zones could be flooded by severe, concentrated rainfall coupled with inadequate local drainage systems. Zone X & X500 –Unshaded Zone X is areas of minimal flood risk.Shaded Zone X and X500 are areas of moderate flood risk due to a storm having a 0.2 percent chance of occurring in any given year. Mandatory flood insurance purchase requirements apply. Base Flood Elevations (BFE) derived from the detailed coastal analysis are shown within this zone as static whole-foot elevations that apply throughout the zone.
Zone VE – The flood insurance rate zone that corresponds to areas within the 1-percent annual chance coastal floodplain that have additional hazards associated with storm waves. The effects of wave hazards between zone VE and the LiMWA line (or between the shoreline and the LiMWA for areas where Zone VE is not identified) will be similar, but less severe than, those in Zone VE. The LiMWA represents the approximate landward limit of the 1.5 foot breaking wave. Mandatory flood insurance purchase requirements apply.Ĭoastal A Zone Line or LiMWA– In coastal areas Zone AE has been divided by a Limit of Moderate Wave Action (LiMWA). Average flood depths derived from detailed analysis are shown within this zone. Zone AO - Areas subject to inundation by the 1-percent annual chance shallow flooding (usually sheet flow on sloping terrain) where average flood depths are between 1 and 3 feet. BFEs derived from detailed hydraulic analysis are shown in this zone. Zone AH – Areas subject to inundation by the 1-percent annual chance shallow flooding (usually ponding) where average flood depths are between 1 and 3 feet. Zone AE – Areas subject to inundation by the 1-percent annual chance floodplain that are determined in the Flood Insurance Study by detailed methods of analyses with Base Flood Elevations (BFE) shown. Because detailed hydraulic analysis is not performed in Zone A, Base Flood Elevations (BFE) and depths are not shown within this zone. Zone A – Areas subject to inundation by the 1-percent annual chance floodplain.
