Because detailed coastal analyses have not been performed, no BFEs or flood depths are shown.Īreas along coasts subject to inundation by the 1-percent-annual-chance flood event with additional hazards due to storm-induced velocity wave action. Federal floodplain management regulations and mandatory purchase requirements apply in these zones.Īreas along coasts subject to inundation by the 1-percent-annual-chance flood event with additional hazards associated with storm-induced waves. Structures located within the CHHA have a 26-percent chance of flooding during the life of a standard 30-year mortgage. No BFEs or flood depths are shown.Ĭoastal High Hazard Areas (CHHA) represent the area subject to inundation by 1-percent-annual chance flood, extending from offshore to the inland limit of a primary front al dune along an open coast and any other area subject to high velocity wave action from storms or seismic sources.
Zone A99 may be used only 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. Average flood depths derived from detailed hydraulic analyses are shown within this zone.Īreas 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.Īreas 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.
BFEs derived from detailed hydraulic analyses are shown in this zone.Īreas subject to inundation by 1-percent-annual-chance shallow flooding (usually sheet flow on sloping terrain) where average depths are 1–3 feet. (Zone AE is used on new and revised maps in place of Zones A1–A30.)Īreas subject to inundation by 1-percent-annual-chance shallow flooding (usually areas of ponding) where average depths are 1–3 feet. Because detailed hydraulic analyses have not been performed, no Base Flood Elevations (BFEs) or flood depths are shown.Īreas subject to inundation by the 1-percent-annual-chance flood event determined by detailed methods. Federal floodplain management regulations and mandatory flood insurance purchase requirements apply in these zones.Īreas subject to inundation by the 1-percent-annual-chance flood event. Structures located within the SFHA have a 26-percent chance of flooding during the life of a standard 30-year mortgage. Special Flood Hazard Areas represent the area subject to inundation by 1-percent-annual chance flood. The study found that black women have a pregnancy-related death rate three times that of white women.Įditor's note: This post was automatically generated using data from Surgo Ventures.#fcfcfc Please Note- Map Quality, Effective Date, and Detail may vary by community.ĭefinitions of FEMA Flood Zone Designations Racial and ethnic disparities continue to exist even when accounting for education and other factors, according to a 2019 CDC study. "I believe the Maternal Vulnerability Index can be a powerful tool for bridging the racial maternal health gap, helping us better understand, and design solutions around, the content and context of women's lives." Ololade Okito, a neonatologist at Children's National Hospital, during a panel discussion about maternal vulnerability. "We know that common sociodemographic factors such as education and income don't protect women of color from being subject to worse maternal health outcomes," said Dr. Black and American Indian and Alaska Native women of reproductive age were more likely to live under worse conditions for maternal health.
