Harris County Flood Control District

The Harris County Flood Control District was established in 1937 by the Texas Legislature in response to devastating floods that reshaped our region. Today, we serve more than 4.7 million residents, including Houston, the nation’s fourth-largest city, by planning, implementing, and maintaining flood risk reduction projects that address the diverse needs of a rapidly growing county. Our work spans 23 watersheds across 1,756 square miles. From major channel conveyance improvements and stormwater detention basins to neighborhood drainage projects, property acquisition, and ongoing maintenance, each effort is tailored to the unique conditions of the communities we serve. We combine engineering expertise, data-driven planning, environmental stewardship, and strong partnerships to deliver long-term, sustainable solutions. Flood risk reduction in Harris County is complex. Flat topography, intense rainfall, aging infrastructure, and continued development require innovative approaches and regional coordination. Through collaboration with federal, state, and local partners, we advance projects that reduce flood risk while supporting community resilience and responsible growth. Above all, our work is about people. Every project represents an opportunity to reduce uncertainty, support economic vitality, and enhance quality of life for current and future generations. Our vision: To enhance quality of life through effective flood risk reduction.
