U.S. Sen. Mary Landrieu announced Friday she will hold hearings to ensure the Federal Emergency Management Agency gives proper guidance to insurance companies on how to provide refunds to flood insurance customers whose rates have been rolled back recently under a law that delayed planned increases to those rates.

The Louisiana Democrat also said in a news release that she will fight to restore $11 million in funding to FEMA’s flood mapping budget in an effort to ensure the agency is using accurate maps when calculating flood risk.

The announcements came after Landrieu met with officials at GNO Inc. about flood insurance issues.

Both that organization and Landrieu were leading critics of the Biggert-Waters Act, which threatened many Louisiana residents with huge increases in their flood insurance premiums.

The effect of that law was delayed earlier this year with the passage of the Homeowner Flood Insurance Affordability Act, which was supported by Landrieu and one of her opponents in this year’s Senate race, Rep. Bill Cassidy, R-Baton Rouge, as well as other members of the Louisiana congressional delegation.

“Hardworking middle-class families should not have to pay flood insurance rates based on inaccurate and flawed maps that fail to recognize the levees that have protected their communities for decades,” Landrieu said. “That’s why I will lead the effort to reverse the president’s $11 million cut to FEMA’s program that corrects out-of-date and flawed maps. And next month, I will use the full power of the Homeland Security Appropriations Subcommittee to hold FEMA accountable for implementing this law correctly and efficiently and give Louisiana a seat at the table as we work toward building a stronger program.”
