The Harris County Flood Control District (Flood Control District) and the Federal Emergency Management Agency (FEMA) are partnering on a flood hazard assessment project that uses the latest available technology and data to produce the county’s most comprehensive and complete set of flood hazard maps and information.
NEW METHODOLOGIES AND TECHNOLOGIES
Using new methodologies and technologies and the most granular data available, FEMA and the Flood Control District will provide a better understanding of flood risks throughout Harris County, including previously unmapped urban flooding, which is flood risk due to rainfall run-off draining through streets and neighborhoods on the way to the bayous.
Other new data and information that will be used include updated terrain data and improved hydrologic and hydraulic modeling technology and methods.
RESULTS THAT IMPACT FUTURE PLANNING
FEMA and the Flood Control District expect many changes to be reflected in the resulting flood risk maps. These changes will impact how future projects, new development, and their associated mitigation strategies are implemented.
