The ongoing government shutdown has already begun to have an adverse impact on the National Flood Insurance Program (NFIP). Both authorization and funding for the NFIP expired on September 30, the end of fiscal year (FY) 2025.
The currently-pending (and now multiple times defeated) continuing resolutions (CRs) would extend authorization and funding for the NFIP, but until a CR (or, more unlikely, an actual funding bill) is enacted, the NFIP is stopped in its tracks.
