The US Federal Emergency Management Agency has unveiled options to develop an affordability program for flood insurance sold under the National Flood Insurance Program (NFIP).

The agency has released the proposals in a framework, as required by the Homeowner Flood Insurance Affordability Act of 2014.

The framework provides the first data-driven analysis of policyholder and potential policyholder incomes by flood risk and home ownership status.

“For the first time, a conversation about affordability and flood insurance is supported by deep data,” agency Director Roy Wright said. “We can move forward with data that will point to more sustainable solutions.”

The NFIP aims to double the number of properties covered by flood insurance from 4 million to 8 million by 2023.
