The National Flood Insurance Program (NFIP) is administered by the Federal Emergency Management Agency (FEMA) (Español) within the Department of Homeland Security (DHS). FEMA develops and provides flood hazard data and maps to local communities such as Yolo County in support of the NFIP. To update these flood maps, known as Flood Insurance Rate Maps (FIRMs), FEMA has undertaken a comprehensive nationwide effort called Map Modernization (Map Mod).

Over the last 25 years there have been numerous instances throughout the nation where the assumption of levees being able to contain the 1% chance flood event were proven invalid. FEMA has responded to this by creating a certification process for levees that needs to be completed prior to FEMA recognizing that a levee will contain a 1% chance flood event. The Map Modernization project will require the levees providing flood protection to be certified in order for them to be reflected as providing flood protection in the updated FIRMs.
