The National Flood Insurance Program still has more than 700 proof of loss forms left to process from homeowners seeking relief from the August flood, the federal program announced today. Policyholders have to submit a proof of loss form as part of their claim process with the NFIP. A news release says the NFIP has given out more than $361 million in advanced payments to help policyholders affected by the August floods, but that more than 700 claims have yet to finish the proof of loss process.
