Kuykendahl Stormwater Detention Basin
Construction is underway at the Kuykendahl Stormwater Detention Basin, which is located on a 288-acre property near Kuykendahl Road and Ella Boulevard in north Harris County. The project is referred to on the map below as P545-01-00.
Stormwater detention basins reduce flooding risks and damages during heavy rain events by safely storing excess floodwater and slowly releasing it back to the bayou when the threat of flooding has passed.
The contractor will use large construction equipment to clear and remove trees, vegetation and soil from the site. Residents and motorists are being urged to observe posted warning signs and obey safety personnel in connection with construction traffic:
- Trucks enter and exit the Kuykendahl project site from Kuykendahl Road.
- One southbound lane of Kuykendahl may be closed outside of morning and evening rush hours to separate truck traffic turning into the project site.
- Improvements to Kuykendahl Road to facilitate traffic flow include:
- Extending the left-turn lane entering the project site by 100 feet, removing 30 feet of curb north of the project site entrance, and extending the left-turn lane from Kuykendahl to Ella by 200 feet.
The Flood Control District appreciates the public’s patience and understanding through the duration of this project.
More About the Project:
The Kuykendahl Stormwater Detention project is one of two regional stormwater detention basins Flood Control District is constructing that will reduce flooding risks and damages in portions of the Greens Bayou watershed in north Harris County. The basins are part of a suite of new flood damage reduction projects in the watershed known as Progress Greens.
The Kuykendahl Basin construction project will remove approximately 3.61 million cubic yards of soil from the site, and when completed, is designed to hold approximately 2,325 acre-feet, or 757.6 million gallons of stormwater. Following construction, the basin design calls for 22.19 acres of native tree and shrub plantings, 12.79 acres of stormwater quality treatment wetlands, and 14.04 acres of other created wetlands to replace those impacted by construction.
An existing channel running through the site, formally identified as HCFCD Unit P245-00-00, will be enhanced and stabilized with natural stable channel design features. These include a bankfull bench or gently sloping terrace at the top of the bank to prevent erosion, riffles and cross-vanes constructed of rocks that are specially placed to slow the water flow, and native woody streamside or riparian vegetation to stabilize the banks, shade the water, and create habitat for birds and other creatures.
In February 2015, FEMA awarded $39.2 million to the Harris County Flood Control District, under the Hurricane Ike Hazard Mitigation Grant Program (HMGP), for the construction of two stormwater detention basins in the Greens Bayou watershed. The Flood Control District is contributing matching funds to the project.
In June 2015, Harris County Commissioners Court awarded a $63.7 million construction contract to low bidder Ceres Environmental Services Inc. to construct the two basins over a three-year time period. The combined basins project will be the largest single construction contract ever managed by the Flood Control District. When complete, the two basins will reduce or remove flooding risks and damages from more than 1,100 structures along Greens Bayou, resulting in avoided damages of more than $90 million.
For more information, questions or comments about these projects, please call the Flood Control District's Project and Study Information Line, which is monitored daily, at 713-684-4040.
....is the name given to a suite of flood damage reduction projects currently active in the Greens Bayou watershed of Harris County. The Harris County Flood Control District is taking the lead in some of those projects, with grant assistance from the Federal Emergency Management Agency (FEMA). In others, the U.S. Army Corps of Engineers will design and construct the project, with partnership assistance from the Flood Control District.
All projects under the Progress Greens umbrella will function together to reduce flooding risks and damages for residents and businesses within the 213 square miles of the Greens Bayou watershed.
