National Flood Insurance Program: The Current Rating Structure and Risk Rating 2.0

Summary

The National Flood Insurance Program (NFIP) is the primary source of flood insurance coverage for residential properties in the United States, with more than five million policies in over 22,000 communities in 56 states and jurisdictions. FEMA is planning to introduce the biggest change to the way the NFIP calculates flood insurance premiums, known as Risk Rating 2.0, since the inception of the NFIP in 1968. The new premium rates are scheduled to go into effect on October 1, 2021, for all NFIP policies across the country.

Risk Rating 2.0 will continue the overall policy of phasing out NFIP subsidies, which began with the Biggert-Waters Flood Insurance Reform Act of 2012 and continued with the Homeowner Flood Insurance Affordability Act of 2014. Under the change, premiums for individual properties will be tied to their actual flood risk. Because the limitations on annual premium increases are set in statute, Risk Rating 2.0 will not be able to increase rates faster than the existing limit for primary residences of 5%-18% per year.

According to FEMA, Risk Rating 2.0 will

reflect an individual property’s risk,

reflect more types of flood risk in rates,

use the latest actuarial practices to set risk-based rates,

provide rates that are easier to understand for agents and policyholders, and

reduce complexity for agents to generate a flood insurance quote.

The NFIP’s current rating structure follows general insurance practices in effect at the time that the NFIP was established and has not fundamentally changed since the 1970s. The current NFIP rating structure uses several basic characteristics to classify properties based on flood risks. Structures are evaluated by their flood zone on a Flood Insurance Rate Map (FIRM), occupancy type, and the elevation of the structure. FEMA uses a nationwide rating system that combines flood zones across many geographic areas, and calculates expected losses for groups of structures that are similar in flood risk and key structural aspects, assigning the same rate to all policies in a group.

According to FEMA, flood zones will no longer be used in calculating a property’s flood insurance premium following the introduction of Risk Rating 2.0. Instead, the premium will be calculated based on the specific features of an individual property, including structural variables such as the foundation type of the structure, the height of the lowest floor of the structure relative to base flood elevation, and the replacement cost value of the structure. The current rating system includes two sources of flood risk: the 1%-annual-chance fluvial (river) flood and the 1%-annual-chance coastal flood. As proposed, Risk Rating 2.0 will incorporate a broader range of flood frequencies and sources than the current system, as well as geographical variables such as the distance to water, the type and size of nearest bodies of water, and the elevation of the property relative to the flooding source.

According to FEMA, although flood zones on a FIRM will not be used to calculate a property’s flood insurance premium, flood zones will still be used for floodplain management purposes, and the boundary of the Special Flood Hazard Area will still be required for the mandatory purchase requirement.
