![]() Mississippi’s first Mapping Activity Statement (MAS) under the FEMA Map Modernization Program (Map Mod) was signed in October of 2003 between MDEQ, MEMA and FEMA. Implementation of the FMMP will include a consideration and prioritization of areas of high growth, of high population densities, with excessive repetitive loss claims, with higher National Flood Insurance Program (NFIP) policy bases, and with the ability to leverage other resources. To implement this agreement and to manage the state’s flood mapping activities, the Mississippi Flood Map Modernization Initiative (MFMMI) was created.īy developing the FMMP, FEMA has created an opportunity for Cooperating Technical Partners (CTP) to manage flood map development, enhancement, and production. Mississippi, through a joint effort between the Mississippi Emergency Management Agency (MEMA) and the Mississippi Department of Environmental Quality (MDEQ), is participating with FEMA Region IV as a Mapping State and a Cooperating Technical Partner (CTP) by an agreement which was signed January 28, 2003. Recognizing the need for adequate and accurate map production, the Federal Emergency Management Agency (FEMA) developed the Flood Map Modernization Program (FMMP) to modernize the flood hazard mapping program, focused on enhancing and converting maps to a digital format. For years, this ability has been hampered by funding and time constraints placed on the system. Base flood elevations derived from detailed analyses are shown at selected intervals within these zones.The ability to plan for flood hazards and mitigation begins with accurate, updated flood maps. These areas have a 26% chance of flooding over the life of a 30 year mortgage. VE - Coastal areas with a 1% or greater chance of flooding and an additional hazard associated with storm waves. Average flood depths derived from detailed analyses are shown within these zones. Base flood elevations derived from detailed analyses are shown at selected intervals within these zones.ĪO - River or stream flood hazard areas, and areas with a 1% or greater chance of shallow flooding each year, usually in the form of sheet flow, with an average depth ranging from 1 to 3 feet. These areas have a 26% chance of flooding over the life of a 30 ‐ year mortgage. Because detailed analyses are not performed for such areas no depths or base flood elevations are shown within these zones.ĪE - The base floodplain where base flood elevations are provided.ĪH - Areas with a 1% annual chance of shallow flooding, usually in the form of a pond, with an average depth ranging from 1 to 3 feet. The SFHA designations which appear within Bay County are explained further below.Ī - Areas with a 1% annual chance of flooding and a 26% chance of flooding over the life of a 30 year mortgage. The areas of minimal flood hazard, which are the areas outside the SFHA and higher than the elevation of the 0.2-percent-annual-chance flood, are labeled Zone C or Zone X (unshaded). Moderate flood hazard areas, labeled Zone B or Zone X (shaded) are also shown on the FIRM, and are the areas between the limits of the base flood and the 0.2-percent-annual-chance (or 500-year) flood. SFHAs are labeled as Zone A, Zone AO, Zone AH, Zones A1-A30, Zone AE, Zone A99, Zone AR, Zone AR/AE, Zone AR/AO, Zone AR/A1-A30, Zone AR/A, Zone V, Zone VE, and Zones V1-V30. The 1-percent annual chance flood is also referred to as the base flood or 100-year flood. ![]() SFHA are defined as the area that will be inundated by the flood event having a 1-percent chance of being equaled or exceeded in any given year. Flood hazard areas identified on the Flood Insurance Rate Map are identified as a Special Flood Hazard Area (SFHA). ![]()
