SFHA are defined as the area that will be. FIRM is short for Flood Insurance Rate Map. Since the data is digitally created it can more easily and accurately used in a Geographic Information System (GIS) map application to provide public access to detailed information regarding flood hazards. See if risk is about to change (new map) Estimate 100-year flood depth in your building. The impact of Risk Rating 2.0: Equity in Action on flood insurance premiums per month in Michigan. Flood hazard areas identified on the Flood Insurance Rate Map are identified as a Special Flood Hazard Area (SFHA). The acronym FIRM stands for Flood Insurance Rate Map. Using the online tool, users can see that more than 54% of Michigan’s existing NFIP policyholders will see a decrease in premiums under Risk Rating 2.0. Under Risk Rating 2.0, fewer people will overpay for flood insurance coverage while owners of properties with higher flood risk will pay more, commensurate with that risk. Each zone reflects the severity or type of flooding. The old methodology also applied nationwide averages for estimating damage costs without taking into account geography-specific considerations.įurther, without the update, all NFIP policyholders would see their rates rise. These zones are depicted on a communitys Flood Insurance Rate Map (FIRM) or Flood Hazard Boundary.
This methodology represents a vast improvement over FEMA’s longstanding rate calculations, which relied heavily on a limited set of risk factors, such as the binary approach of whether a property is “in or out” of a designated flood zone, or when a community first entered into the NFIP. The new National Flood Insurance Program (NFIP) rates are based on a more comprehensive suite of data that better reflects each property’s flood risk, including the frequency and types of flooding, the proximity to a body of water, the size of the water source, detailed elevation data, and the estimated cost to rebuild. The maps also show that fewer than 3% of policyholders with single-family homes will see rates rise by $20 or more per month. The tool visually represents the almost 1.2 million policyholders who will see rates drop, and shows that a majority of policyholders will see minimal increases, with costs rising no more than $10 per month. The DFIRMs are digitally converted flood insurance rates maps that will be compatible with GIS (Geographic Information Systems).
