Q122 Study
The Harris County Flood Control District completed the Cedar Bayou Flood Risk Reduction Study (FRRS), which was funded by a Texas Water Development Board grant. This study focused on evaluating long-term flood risk reduction strategies for the watershed while outlining improvements that could provide benefits in the short term.
A long-term proposed solution was identified by the study to provide a large regional detention basin, approximately 155 acres in size, providing approximately 335 million gallons of storage volume. Additionally, channel improvements to widen and deepen Q122-00-00 upstream were identified as part of the long-term proposed solution.
The long-term proposed solutions will be implemented as funding becomes available with the estimated total cost for the ultimate solution reaching roughly $31.5 million.
The long-term project benefits include more effective channel conveyance to contain future 100-year flows and the removal of the 100-year floodplain from up to 35 structures, and an estimated reduction of $2.2 million in damages.
For short-term improvements, Harris County Flood Control District is performing a Preliminary Engineering Report to identify a flood mitigation project along Q122-00-00.
