Project Description

This project is currently undergoing the Preliminary Engineering Report (PER) and conceptual design stage. This stage will result in more detailed recommendations for flood damage reduction projects and an implementation strategy for those projects.


Q130-00-00 is a 2.87-mile long unnamed tributary near the northeastern corner of Harris County, roughly bisected by Highway 90.

Project limits are from the crossing with Cedar Bayou (Q100) to Crosby-Eastgate Rd.


This project is currently moving toward the final stage of the Preliminary Engineering Report.

Bond Listing

Bond Project F-44 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 $18 million.

Cedar Bayou Tributary Q130-00-00 Advanced Feasibility Study

The Harris County Flood Control District (HCFCD) completed the Q130-00-00 Advanced Feasibility Study, which is funded from 2018 Bond Program. The objective of Q130-00-00 Advanced Feasibility Study is to conduct a detailed investigation of the existing flood hazards in the watershed and identify potential future drainage improvements aimed at reducing future flood risk throughout the watershed.

The long-term proposed solution identified by the study are channel improvements to widen and/or deepen Q130-00-00 upstream, and structure improvements to increase the capacity of existing bridges and culverts, and a large regional stormwater detention basin (approximately 150 acres in size and providing approximately 160 million gallons of storage volume). The short-term recommendations are acquisition of right-of-way (ROW) for future improvements and the initial construction of the regional stormwater detention basin.

The project benefits include more effective channel conveyance to contain future 100-year flows as well as the removal of inundation of up to 29 structures upstream, in the 500-year event, up to 68 structures in the 100-year event, and 41 structures in the 10-year event. Additional project benefits include, the removal of inundation from approximately 786 acres and three miles of roads in the 100-year event and an estimated reduction of $6.5 million in damages.

stormwater detention basin

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.
