While governments are doing all they can to alleviate the impact of floods, everyone should play a role in protecting themselves.

This is important because the National Flood Insurance Program’s (NFIP) floodplain management regulations are enforceable in the SFHA, including the mandatory purchase of flood insurance.įEMA encourages everyone to get flood insurance, even if you don’t live in a high-risk flood zone. The San Antonio Floodplain Viewer also shows moderate flood hazard areas, which are represented between the limits of the base flood (1 percent annual chance) and the 0.2 percent annual chance (or 500-year) flood.īy no coincidence, the Special Flood Hazard Area (SFHA)-as defined by FEMA-is the land area covered by the floodwaters of the base flood-that is the 1-percent annual chance flooding event. The San Antonio River Authority Floodplain Viewer outlines the 1-percent annual chance flood boundaries-indicating that those areas will be inundated by a flood event that has a 1-percent chance of being equaled or exceeded in any given year. Zone AO, Flood insurance rate zone that corresponds to areas of shallow flooding (usually sheet flow on sloping terrain) with average depths between 1 and 3. Thus, the base flood can also be called the “1-percent annual chance flood.” The Federal Emergency Management Agency (FEMA) releases the digital flood insurance rate maps (DFIRMs) on a community-by-community basis. These maps are created by the Federal Emergency Management Agency (FEMA) and are used to determine flood insurance rates and to help communities plan for and respond to floods. The base flood, or 100-year flood, is the flooding event that statistically has a 1-percent chance of occurring in any given year. A flood map is a representation of areas that have a high risk of flooding.
