A panel of the Senate Appropriations Committee has voted to effectively stop the Federal Emergency Management Agency from implementing a provision of the 2012 law reauthorizing the National Flood Insurance Program that mandates phased-in rate increases for grandfathered properties.

The provision barring FEMA from implementing Sec. 207 of the 2012 Biggert-Waters Act was passed by the Senate Appropriations Subcommittee on Tuesday and will be considered by the full committee on Thursday.

The subcommittee is chaired by Sen. Mary Landrieu, D-Louisiana, who had pushed a stronger three-year delay. But she said she did not want to "risk losing an opportunity for a one-year" delay. She said a lot of senators from non-coastal states still support the legislation passed last year to make the flood insurance program more financially self-sustainable.
