![]() ![]() National National Academies Academies of 1997 Technical. The Q3 cannot be used as the official NFIP map for site design or flood risk determinations. FEMA's Flood Hazard Mapping Program: A Progress Report (May 2001). FEMA has also produced Q3 Flood Data, which includes certain features of the FIRM, and may be used for insurance purposes and planning activities. River Corridors include the width of the meander belt of a river and an additional 50’ buffer to allow for a stable wooded bank when the river is at its equilibrium / least erosive slope. More recent flood map products include digital FIRMs, which are created using digital methods and can be incorporated into a community's Geographic Information System (GIS). River Corridors are delineated by the Department of Environmental Conservation as described in the Flood Hazard Area & River Corridor Protection Procedure. The FHBM is an older version of a flood map and is based on approximate data. The FBFM is no longer produced current FIRMs include all of this information. The FBFM is a version of a flood map that shows only the floodway and flood boundaries. These maps are continually being updated due to. Flood Insurance Rate Maps (FIRM) will generally show a community’s base elevations and flood zones. ![]() Zones are categorized by their risk for flooding and represented by letters on a map. At a minimum, flood maps show flood risk zones and their boundaries, and may also show floodways and Base Flood Elevations (BFEs). Severe storms and flooding have the potential to cause hundreds of millions (or even billions) of dollars in damage each year. The Federal Emergency Management Agency (FEMA) maps flood zones for the National Flood Insurance Program. The FIRM is the most common type of map and most communities have this type of map. The following site is accessible to Federal Emergency Management Agency (FEMA) staff, and FEMA contractors, mapping partners, mapping program stakeholders, and National Flood Insurance Program (NFIP) map users, as well as Risk MAP staff and state, tribal, and local mitigation planners. A Flood Insurance Rate Map (FIRM), Flood Boundary and Floodway Map (FBFM), and Flood Hazard Boundary Map (FHBM) are all flood maps produced by FEMA. ![]()
