Project Description

The project includes the deepening of an existing Stormwater Detention Basin and channel conveyance improvements from north of the Sam Houston Tollway to where the tributary joins Sims Bayou near Trafalgar Drive. This project will reduce the risk of flooding for residents, and therefore, shrink the regulatory floodplain while avoiding adverse impacts to Sims Bayou or to the natural environment.

The construction of this project will be funded in part by the 2018 Bond Program approved by Harris County voters on August 25, 2018. The Flood Control District is pursuing the remaining funds needed to construct this project from various federal sources.


The Harris County Flood Control District has a significant number of flood damage reduction projects occurring all over Harris County as part of its on-going Capital Improvement Program (CIP), Operations and Maintenance, and the 2018 Bond Program.
