Mandatory flood insurance purchase requirements and floodplain management standards apply. No Base Flood Elevations (BFEs) or depths are shown.
Zone A99 may only be used when the flood protection system has reached specified statutory progress toward completion. These are areas of special flood hazard where enough progress has been made on the construction of a protection system, such as dikes, dams, and levees, to consider it complete for insurance rating purposes. Areas subject to inundation by the 1 percent annual chance flood event, but which will ultimately be protected upon completion of an under-construction Federal flood protection system. Areas that result from the decertification of a previously accredited flood protection system that is determined to be in the process of being restored to provide base flood protection. Communities are encouraged to adopt more restrictive requirements for these areas. Mandatory flood insurance purchase requirements and floodplain management standards apply. Some Zone AO areas have been designated in areas with high flood velocities such as alluvial fans and washes. Average flood depths derived from detailed hydraulic analyses are shown in this zone. Areas subject to inundation by 1 percent annual chance shallow flooding (usually sheet flow on sloping terrain) where average depths are between 1and 3 feet. Base Flood Elevations (BFEs) derived from detailed hydraulic analyses are shown in this zone. Areas subject to inundation by 1 percent annual chance shallow flooding (usually areas of ponding) where average depths are between one and three feet. Areas subject to inundation by the 1 percent annual chance flood event determined by detailed methods. (In unincorporated Lee County, the county has estimated BFEs in these areas.) Because detailed hydraulic analyses have not been performed, no Base Flood Elevations (BFEs) or flood depths are shown. Areas subject to inundation by the 1 percent annual chance flood event generally determined using approximate methodologies. The land area that could be covered by the floodwaters of the base flood is where the NFIP's floodplain management regulations must be enforced and where the mandatory purchase of flood insurance applies for federally backed mortgages. The requirement also extends to private mortgage companies backed by the FDIC or other federal agencies. Therefore, many private mortgage companies also require flood insurance on properties in the SFHA.

The X zone (also known as “low–risk flood zone”) is an area outside of the That means a flood could happen this year and again the next year. The Special Flood Hazard Area is an area that has a 1 percentĬhance, or a 1 in 100 chance, of a flood happening in any given year. The 1 percent annual chance flood is also referred to as the base flood and you may also hear and see the term 100-year flood, however, see the below information about that term and the misconception associated with it.įlood” Misconception - People sometimes hear the phrase “100-year”įlood and think a flood happens only once in one hundred years. The floodplain on Flood Insurance Rate Maps is identified as a Special Flood Hazard Area (SFHA). The SFHA is an area that could be inundated by a flood event with a 1 percent chance of reaching or exceeding base flood elevations in any given year. 50% Rule: Substantial Improvement/Substantial Damage.Notice of Proposed Changes to FIRM Maps.Lee Concurrence for Letters of Map Correction.Landscaping Requirements/ Preserve Management.
