Project Description

This project will improve channel conveyance improvements to reduce flooding risks along the Cedar Bayou tributary formally identified as HCFCD Unit Q130-00-00.

Location

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

Stage

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-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.

Q130* Advanced Feasibility Study

The Harris County Flood Control District (HCFCD) initiated 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.

This detailed analysis resulted in a recommendation of a preferred alternative short-term solution to move forward in the Preliminary Engineering Report (PER) phase. The short-term recommendation included channel conveyance improvements, structure improvements from downstream of Crosby Eastgate Road, to upstream of US 90, and construction of two detention ponds containing approximately 30 million gallons of storage volume.

The preferred alternative solution would be improved to a long-term proposed solution, as additional funding becomes available, thereby providing incremental benefits to the watershed as more drainage improvements are constructed. The estimated total construction cost for the short-term preferred alternative, is approximately $17.4 million and the long-term solution cost is approximately $44.9 million. This is based on excavation quantities for basin and channel improvements, with a 20% contingency factor.

*Note: It is worth noting that the right-of-way (ROW) acquisition is an evolving progression and thus the proposed estimates on basin footprint areas and corresponding storage capacities are considered planning-level until tracts and parcels are officially acquired by HCFCD and the detailed design phase commences.

Proposed Detention Pond

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.

PROJECT LIFECYCLE

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.
