Houston faces serious flood risk — and no single agency is in charge. Three main players share the work: the Harris County Flood Control District (HCFCD), the U.S. Army Corps of Engineers, and the City of Houston. Each has its own role, but their efforts overlap. This guide breaks down who does what, how big decisions get made, and what changed after Hurricane Harvey in 2017.
Houston's geography works against it: flat land, clay-heavy soil that resists absorption, dense paving, and a front-row seat to Gulf storms. Even a moderate rainstorm can flood streets and homes quickly. Three agencies carry the main responsibility for managing that risk. The Harris County Flood Control District focuses on the county's bayous, channels, and detention basins. The U.S. Army Corps of Engineers partners on large-scale infrastructure projects. The City of Houston manages drainage inside city limits. After Hurricane Harvey caused catastrophic damage in 2017, billions of dollars in new funding were committed to flood protection projects across the region.
Use this guide to understand the chain of responsibility before the next big storm. Find out which agency oversees the drainage or waterway nearest your home. Learn how funding decisions are made and who approves major flood control projects. Then take that knowledge into community meetings, budget hearings, or conversations with your council member or county commissioner.

Flood control connects directly to housing affordability, home insurance costs, and neighborhood investment decisions. Areas with repeated flooding often see lower property values and higher insurance premiums. Understanding how flood control funding is allocated can help residents advocate for equitable infrastructure improvements across all Houston communities.
Flooding affects more Houston-area residents than almost any other natural hazard. Knowing which agencies are responsible — and how they coordinate — helps you ask better questions, hold officials accountable, and make smarter choices for your household and neighborhood.
