Harris County's Flooding History

A major flood occurs somewhere in Harris County about every two years. Most of the flooding is in areas developed prior to the current understanding of flood potential and prior to regulations restricting construction in flood-prone areas.

• Hurricane Harvey
• Spring Floods 2016
• Hurricane Ike 2008
• Tropical Storm Allison 2001

Capital Improvement Program

Capital projects include those major projects that reduce flooding risks and damages by increasing stormwater conveyance capacity in bayous and drainage channels, or by excavating stormwater detention basins. Stormwater detention basins reduce flooding risks and damages during heavy rain events by safely storing excess stormwater and slowly releasing it back to the bayou when the threat of flooding has passed.

• Subdivision Drainage Projects

Maintenance Programs

Along with mowing and routine maintenance of the county’s 2,500 miles of channel, dozens of stormwater detention basins and thousands of buyout lots, the Flood Control District conducts major maintenance to repair damage caused by storms and erosion.

• Property Management Program
• Abandoned Bridge Program
• Vegetation Management
• Emergency Repairs - COMPLETED
