Cedar Bayou Flood Risk Reduction Study

The Harris County Flood Control District held its third and final public meeting for the Cedar Bayou Flood Risk Reduction Study on Wednesday, May 9, 2018. The purpose of this meeting was to:

  • Provide information about the study;
  • Share conceptual recommendations for future flood risk reduction projects in the Cedar Bayou watershed that have been developed during the study, and
  • Gather feedback from the public about the recommendations. 

About the Study

The purpose of the Cedar Bayou Flood Risk Reduction Study is to identify flood risks, develop options to mitigate that risk, update the Harris County Flood Control District Hazard Mitigation Plan, and explore enhancements to the existing flood warning system. The principal focus will be on streams located in Harris County. The scope of the feasibility study includes investigating 18 of the tributaries on the Harris County side of the watershed in greater detail, as well as the main stem of Cedar Bayou, for a total study area comprised of more than 90 stream miles. As part of the planning process, input from the surrounding jurisdictions will be considered and, if appropriate, included in the recommendations for improvements to the Cedar Bayou watershed.

The study will update floodplain modeling information along Cedar Bayou on studied streams, as well as develop detailed modeling for several previously unstudied streams within Harris County. In addition, the study will investigate structural and nonstructural flood damage reduction projects for Cedar Bayou and selected tributaries within Harris County and will develop a flood risk reduction plan for the watershed that considers environmental concerns such as stream processes and the natural environment. Funding for the study is made possible by a $250,000 Flood Protection Planning Grant awarded to the Flood Control District by the Texas Water Development Board. The Flood Control District has already committed an additional $450,000 towards the work effort.

Study Timeframe

The study, which began in February 2017, is expected to take approximately one year to complete.

During the study, the Flood Control District will hold three public meetings to gather input and share information about the study. The final deliverable will be a report with recommendations for flood risk reduction projects throughout the Cedar Bayou watershed and provide associated cost estimates for the recommended projects.
