Base Level Engineering results have been prepared to meet all technical, engineering and mapping standards so that they may be used to update FIRMs in the case that the current inventory is not able to be validated.
FEMA is working with its Federal and State partners to identify watershed basins in need of flood risk information. Additional watersheds will be invested in each fiscal year, if your community is interested in having watersheds in your vicinity assessed, contact us to let us know of your interest.
Watershed-wide Base Level Engineering assessments develop the following flood risk information, available for download through this site:
Additional items may be available for download including Hazus analysis (county or HUC8 level), Flood Risk Report, and/or Base Level Engineering Technical Report.
FEMA Region 6 is partnered with the InFRM team to work towards a future state where communities throughout the Region have a minimum dataset that describes the flood risk in their vicinity and allows them to determine a Base Flood Elevation. Base Level Engineering information does not replace the information shown on any current effective FIRM panel in a community, but may be used to identify areas with significant change in the floodplain delineation, water surface elevation or depth since the last flood risk study (both reduction and expansion) should be investigated with communities further.
FEMA will coordinate with local communities prior to initiating an update to the existing flood hazard information shown on FIRM panels across the nation.
FEMA Region 6 includes Arkansas, Louisiana, New Mexico, Oklahoma, and Texas.
