The U.S. Army Corps of Engineers Galveston District (Corps) and Harris County Flood Control District broke ground in 2015 on the $58 million Greens Bayou Federal Flood Risk Management Project in north Harris County.
The project includes approximately 3.7 miles of channel conveyance improvements from Cutten Road to Veterans Memorial Drive and approximately 108 acres of stormwater detention storage in the Antoine Stormwater Detention Basin, formally known as HCFCD Unit P500-05-00 and located near the intersection of Antoine Drive and the Sam Houston Tollway.
Phase II construction of the project began in late 2016 and is expected to take approximately three years to complete. The Corps awarded a $21.4 million contract to Lecon Inc. for the Phase II work, which includes completion of the north cell of the basin, located north of West Greens Road; excavation of the south cell, which is located south of West Greens Road; and construction of the channel conveyance improvements from Cutten Road to Veterans Memorial Drive. Phase I of the project, which included excavation of the north cell and construction of an outfall structure to Greens Bayou, was completed in 2016. Lecon was awarded the $5.7 million contract for Phase I.
