Officials in West University Place recently received a briefing on potential updates to FEMA flood maps that could affect how flood risk is represented in the area. The presentation to the West University City Council focused on how updated rainfall data, improved terrain modeling, and completed flood risk reduction projects are influencing the next generation of flood mapping.
Emily Woodell, Chief External Affairs Officer for the Harris County Flood Control District, presented the update and explained how the Flood Control District is supporting FEMA’s mapping effort. The Flood Control District provides engineering data, local expertise and information about completed flood risk reduction projects across Harris County to help ensure the modeling reflects real conditions on the ground.
Much of the discussion related to the Brays Bayou watershed, which is near West University Place. Woodell noted that the updated modeling includes major improvements along Brays Bayou completed through Project Brays, a long running federal, county, and local partnership designed to improve channel capacity and reduce flood risk for surrounding neighborhoods, including areas near West University (read more about the history of Project Brays).
The modeling also reflects updated rainfall estimates that show storms in the region can produce more intense rainfall than older federal standards assumed. By combining this updated rainfall information with improved topographic data and completed infrastructure projects, engineers are able to develop a clearer picture of flood risk across the watershed.
Woodell emphasized that the maps currently being reviewed are still preliminary. Floodplain administrators and technical experts are examining the modeling before FEMA releases preliminary maps to the public. At this stage, the maps do not regulate development or affect flood insurance requirements.
For West University residents, the updates provide an early look at how flood risk may be represented in future FEMA maps. As the process moves forward, residents and local officials will have opportunities to review the maps and learn more about how updated data and completed projects are shaping the understanding of flood risk along Brays Bayou.
The Flood Control District is continuing to make historic progress in flood risk reduction projects and maintenance efforts thanks to voter support and dedicated staff. Stay informed by following us on social media.
