Why are floodplain maps being updated?

The maps are being updated because the majority of the maps are based on analyses that were performed over 25 years ago. Watershed conditions such as land use and topography have changed, and there has been significant added development. Furthermore, analysis tools and historical data collection have improved over time and will increase map accuracy.

National Flood Insurance Program

Flood hazard mapping is an important part of the National Flood Insurance Program (NFIP), as it is the basis of NFIP regulations and flood insurance requirements. The Federal Emergency Management Agency (FEMA) maintains and updates data through Flood Insurance Rate Maps (FIRMs) and risk assessments.

Floodplain Properties

In many cases, mapped drainage boundaries have not changed, although these maps pertaining to the City of Hutto may incorporate additional properties, or show previously included properties as no longer affected by previous boundaries. At this time, 86 additional properties in Hutto are now in the floodplain due to map changes, and a handful of properties have been removed from the floodplain.
