![]() ![]() That is why critical flood mapping data is necessary and essential for communities. Using Flood Insurance Rate Maps (FIRMs) for Mandatory Purchase and Floodplain ManagementįEMA’s flood map data informs the catastrophe models used in the development of rates under NFIP’s pricing approach. We are upholding statutory requirements by:Įxisting statutory limits on rate increases require that most rates not increase more than 18% per year. What Didn’t Change Under NFIP’s Pricing Approach With the implementation of NFIP’s pricing approach, FEMA is now able to equitably distribute premiums across all policyholders based on home value and a property’s flood risk, and set rates that are fairer and more equitable. These include flood frequency, multiple flood types-river overflow, storm surge, coastal erosion and heavy rainfall-and distance to a water source along with property characteristics such as elevation and the cost to rebuild. With NFIP’s pricing approach, FEMA is using new capabilities and tools to address rating disparities by incorporating more flood risk variables. NFIP’s pricing approach enables FEMA to set rates that are fairer and ensures up-to-date actuarial principles based upon new technology, including modeling. ![]() Policyholders with lower-valued homes may have been paying more than their share of the risk while policyholders with higher-valued homes may have been paying less than their share of the risk. In addition, the 1970s legacy rating methodology did not account for the cost of rebuilding a home. FEMA is building on years of investment in flood hazard information by incorporating private sector data sets, catastrophe models, and evolving actuarial science. ![]() The 1970s legacy methodology did not incorporate as many flooding variables as NFIP’s pricing approach. Since the 1970s, rates have been predominantly based on relatively static measurements, emphasizing a property’s elevation within a zone on a Flood Insurance Rate Map (FIRM). Purchasing flood insurance is the first line of defense against flood damage and a step toward a quicker recovery following a flood. The latest community-wide FIRM revision has just completed and the new Effective Firms were formally adopted by FEMA on October 13, 2022.Why FEMA Undertook NFIP’s Pricing ApproachįEMA is committed to building a culture of preparedness across the nation. The City of Corpus Christi joined the NFIP in 1970 and has undergone several FIRM revisions since. As a property owner/renter, you can use these maps to get a reliable indication of what flood zone you’re in. ĬLICK HERE to learn more about reading FIRM maps.Ī FIRM will generally show a community’s base flood elevations, flood zones, and floodplain boundaries. In addition, these properties face hazards associated with coastal storm waves and storm surge.įor more information about understanding your flood risk, visit. Zones VE or V - These properties also have at least a 26 percent chance of flooding over the life of a 30-year mortgage. Zones AE, A, AH, AR, A99, or AO - These properties have at least a 26 percent chance of flooding over the life of a 30-year mortgage. High-risk areas are identified on the FIRMs as: Zone X- These properties are in an area of overall lower risk. The risk is reduced in these areas but not eliminated. Shaded Zone X- These properties are in moderate to the low-risk area. Moderate-to low-risk areas are identified on the Flood Insurance Rate Maps (FIRMs) as: ![]()
