The FY2027 President's Budget requests $185.0M for Floodplain Management and Flood Mapping, within Homeland Security's National Flood Insurance Program account. That is down 3.7% on the FY2026 figure of $192.2M, which is a continuing-resolution annualized figure, not an enacted appropriation.
FY2025–FY2027
| Fiscal year | Basis | Amount |
|---|---|---|
| FY2025 | enacted | $197.1M |
| FY2026 | CR annualized | $192.2M |
| FY2027 | request | $185.0M |
The prior-year column is a CR annualized figure — the rate a continuing resolution funds at, not an enacted appropriation. The two are different numbers and are not interchangeable. Bases are separate columns and are never summed into one figure.
Homeland Security discretionary budget authority
From the OMB Public Budget Database — clean, summable, and the figure to cite for an agency total. It is the whole of Homeland Security's discretionary request, not a total of the parsed lines above, and this page never adds the two together.

At the national level, the program establishes the regulatory framework for communities that participate in the NFIP by developing policy, guidance, standards, and technical publications. Flood Mapping, which includes the Risk Mapping, Assessment and Planning (Risk MAP) program, funds activities that provide tools such as flood maps and preliminary flood hazard data for communities to use to know which areas have the highest risk of flooding. The Risk MAP program provides user-friendly products to analyze flood risk and support planning and development practices.
