Mayor John Whitmire Allocates $95 Million for Houston Bayou Drainage and Stormwater Basins

HOUSTON — Mayor John Whitmire and the Houston City Council approved a $95 million municipal capital drainage funding agreement on Monday, authorizing Houston Public Works to construct three regional stormwater detention basins and widen primary concrete drainage culverts across low-lying neighborhoods in North and East Houston.

The project targets flood-vulnerable neighborhoods along White Oak Bayou, Buffalo Bayou, and Greens Bayou that suffered chronic street and residential flooding during intense summer convective thunderstorms and tropical rain systems.

Accelerating Flood Mitigation for Vulnerable Houston Neighborhoods Houston's flat coastal topography and heavy clay soils create severe drainage challenges, where torrential rainfall exceeding three inches per hour can rapidly overwhelm neighborhood storm sewers and flood residential streets.

"Houstonians have lived in fear of flooded streets and damaged homes for far too long, and our administration is taking aggressive, practical action to fix our drainage infrastructure," Mayor John Whitmire said along White Oak Bayou in North Houston. "This $95 million investment builds massive stormwater detention basins that hold millions of gallons of rainwater during storms, widens neighborhood culverts, and clears blocked ditches, ensuring floodwaters drain quickly away from homes and family businesses."

Drainage Infrastructure Packages Funded The $95 million allocation finances:

• Three Regional Stormwater Detention Basins: Excavating 250 acres of engineered earthen holding basins capable of capturing over 800 million gallons of stormwater.
• 35 Miles of Neighborhood Box Culvert Enlargements: Replacing undersized 24-inch storm pipes with high-capacity 60-inch concrete box culverts in Kashmere Gardens, Independence Heights, and Sunnyside.
• Automated Hydrodynamic Debris Screens: Installing automated mechanical rakes that prevent tree branches and urban debris from clogging storm sewer outfalls.

Civic club presidents, neighborhood association leaders, and civil engineering federations commended the mayor's infrastructure focus, highlighting that expanded detention basins provide immediate flood protection for working-class neighborhoods.
