This project will improve channel conveyance improvements to reduce flooding risks along the Cedar Bayou tributary formally identified as HCFCD Unit Q134-00-00 and Q134-01-00.


Q134-00-00 and its sub-tributary Q134-01-00 are unnamed tributaries near the northeastern corner of Harris County, roughly bisected by F.M. 1960, and located just east of F.M. 2100.


This project is currently undergoing detailed alternatives analysis as part of the feasibility investigation stage. This effort will result in more detailed recommendations for flood damage reduction projects and an implementation strategy for those projects.

Bond Listing

Bond Project F-45 is a “Local Only” project, which means there is no funding partner identified at this time, and the project will be funded entirely from the 2018 Bond Program. The Bond Project List includes a total allocation for all stages and phases of this project of $11 million.

Q134 Advanced Feasibility Study

The Harris County Flood Control District (HCFCD) completed the Q134-00-00 Advanced Feasibility Study, which was funded as part of the 2018 Bond program and served as a continuation of the 2018 Cedar Bayou Flood Risk Reduction Study. The Advanced Feasibility Study involved an update to the existing flood hazards assessment and a more detailed alternative analysis to evaluate various drainage improvements to reduce future flood risk throughout the watershed.

This study focused on evaluating long-term flood risk reduction strategies for the watershed while outlining an initial phase of improvements that could provide benefits in the short-term. The long-term proposed solution consisted of a large regional detention pond (approximately 216 acres in size and providing approximately 342 million gallons of storage volume), channel improvements to widen/deepen both Q134-00-00 and Q134-01-00 upstream of their confluence, and structure improvements to increase the capacity of existing bridges/culverts. The short-term recommendations included construction of a new outfall channel near the Forest Manor neighborhood, acquisition of right-of-way for future improvements, and the initial construction of the regional detention pond.

The implementation of the long-term proposed solution would be phased as funding becomes available with the estimated total cost for the ultimate solution equal to roughly $47 million. The project benefits include more effective water containment for the Forest Manor neighborhood that complements local drainage improvements, particularly north of FM 1960.

Phase 1 Improvements

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.

The map will be updated when projects advance or when more information becomes available.


Every flood damage reduction project is unique. Yet each project begins and ends, with common and predictable milestones along the way. Whether a project moves forward – and how quickly – depends on many factors, including the availability of funding at each milestone, shifting community priorities for flood damage reduction, and other changing circumstances (such as the price of trees or concrete) from year to year.
