PROJECT DESCRIPTION

Bond Project C-01 will construct channel conveyance improvements and a pair of stormwater detention basins to reduce the risk of flooding by taking in excess stormwater during heavy rain events and then releasing it slowly back to the channel when the threat of flooding has passed. Excavation of the stormwater detention basins began in winter 2020 and is anticipated to hold 119 acre-feet, or nearly 39 million gallons, of stormwater that might otherwise flood homes and businesses.

This project is part the Watershed-Wide Project Implementation Program for Halls Bayou.

Location

The stormwater detention basin sites are located on two sites along Tributary P118-26-00, one south of E. Helms Road and the other is at the corner of E. Helms Road and Lillja Road.

Stage

This project phase is in the CONSTRUCTION stage.

Bond Project Listing

Bond Project C-01 is a “Partnership” project. The Flood Control District received a Community Development Block Grant for Disaster Recovery (CDBG-DR) grant for approximately $975,000 in connection with this project.

To fund the future conveyance improvements and additional stormwater detention basin improvements, the Flood Control District applied to the Texas General Land Office for a Community Development Block Grant for Mitigation (CDBG-MIT) grant in October 2020 in the amount of approximately $20.2 million.

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. Click the Project ID on the Map to learn about projects’ details. Some early-stage projects are not highlighted on the map. 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.
