Houston City Council Approves $50 Million Greens Bayou Flood Detention Basin and Drainage Overhaul

HOUSTON, TX — The Houston City Council voted 15–2 to approve a $50 million land acquisition and engineering contract to construct the Greens Bayou Regional Stormwater Detention Basin in Northeast Houston.

Protecting Vulnerable Neighborhoods from Severe Flooding

The 140-acre engineering project will excavate a 1.2 billion-gallon stormwater detention reservoir designed to absorb flash flood surges during tropical depressions, providing flood reduction for an estimated 12,000 single-family homes and small businesses in Greenspoint and East Houston. Council members emphasized that regional detention basins are essential to prevent recurring bayou overtopping.

Mayor John Whitmire stated that public safety and flood mitigation remain Houston’s top priorities, ensuring infrastructure dollars protect vulnerable working-class communities.

Community Advocacy and Project Timeline

Northeast Houston civic clubs commended the project approval after years of community organizing following Hurricane Harvey.

Houston Public Works will deploy excavation contractors in November 2026.

Operational Completion

Phase 1 detention storage will become operational by spring 2028 ahead of hurricane season.
