Project Description

This project has completed the Preliminary Engineering Report (PER) stage to identify a drainage improvement project for the Q130-00-00 watershed (a tributary of Cedar Bayou).

Location

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

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

Stage

This project is in the DESIGN stage.

Bond Listing

Bond Project F-44 is a “Local Only” project, meaning that the project will be funded entirely from the 2018 Bond Program without any partner funding. The Bond Project List includes a total allocation of $18 million for all stages and phases of this project.

Cedar Bayou Tributary Q130-00-00 Advanced Feasibility Study

The Harris County Flood Control District completed the Q130-00-00 Preliminary Engineering Report (PER) in late 2022 with funding from the 2018 Bond Program. The PER investigated the existing flood hazards in the watershed in detail and identified potential future drainage improvements to reduce future flood risk throughout the watershed within the allocated bond budget.

The recommended short-term proposed solution consists of approximately 3,300LF of Natural Stable Channel Design (NSCD) channel improvements and two detention basins (approximately 140 acres total in size and providing approximately 74 million gallons of storage volume). The total estimated cost for the short-term solution is roughly $16.6 million, which is within the current bond budget. This first phase of the project will provide the removal of 10 structures, 1.46 miles of inundated roadways, and 213 acres of inundated area from 500-year floodplain.

The 2nd phase of the project will provide 25-yr system capacity as well as the removal of more structures, inundated roadways, and inundated area from the 500-yr floodplain. Implementing the long-term proposed solution would be phased as funding becomes available.

A detailed design stage is anticipated to begin in early 2023.

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.
