Barrett Station Neighborhood Drainage Improvements
Houston, TX
This drainage improvement initiative addressed chronic flooding in Barrett Station, a 225-acre residential neighborhood in northeast Harris County. Over the past decade, more than 240 homes in the area had been affected by repeated storm events, prompting the need for a comprehensive and lasting solution.
In close coordination with Harris County Engineering and the Harris County Flood Control District, the project team assessed existing drainage conditions and developed targeted improvements. Two-dimensional HEC-RAS modeling and Atlas 14 rainfall data supported evaluation of flood scenarios for 2-, 10-, and 100-year storm events. Design alternatives were tested and refined using graphical analysis to aid decision-making.
The final design included a combination of diversion ditches, channel upgrades, and replacement of undersized driveway culverts. A six-acre detention pond was also constructed, featuring custom inlets and outlet structures to regulate flows and reduce flood impacts across the neighborhood.
These improvements removed 89 homes from the mapped floodplain and lowered 10-year water surface elevations by two to 15 inches. The project has strengthened neighborhood safety, improved mobility, and increased long-term property resilience.
