When you think of flood risk reduction, trees might not be the first thing that comes to mind, but they play a surprisingly critical role in Harris County’s efforts to manage stormwater and reduce the risk of flooding for our communities. The Harris County Flood Control District’s mission is not only to implement effective stormwater management plans and maintain essential infrastructure, but also to do so with deep respect for the environment and community values. That’s where trees come in.

Each year, the Flood Control District plants between 12,000 and 15,000 trees across the county. These efforts replace trees lost during construction projects, enhance capital improvements, and support routine maintenance goals. Whether it’s preserving significant trees ahead of construction or planting new ones near stormwater detention basins and along channels, the Flood Control District is committed to using reforestation measures where appropriate.

Tree planting isn’t just about aesthetics. Trees planted in strategic, non-conveyance areas, such as upper channel slopes and detention basins, help create a mature forest canopy. This canopy suppresses unwanted underbrush, reducing the need for mowing and saving maintenance resources. Even more importantly, trees can help:

• Slow and reduce stormwater runoff
• Improve stormwater quality by minimizing silt entering waterways
• Support soil infiltration of stormwater
• Intercept rainfall in their canopies, reducing surface runoff
• Filter pollutants from the air
• Provide wildlife habitat
• Cool the surrounding environment and beautify the landscape

The Flood Control District also actively partners with individuals and organizations to expand its reforestation efforts. Community members interested in tree planting events must submit a written request to the Flood Control District’s Property Management Department. The request should include a project description and a map of the intended location. Approval involves careful site screening, review by a Flood Control District forester, and the submission of a maintenance plan. In some cases, the Flood Control District can even provide trees for the event.
