Irving: Delaware Creek Drainage Improvement Project Moves Forward
In April, the Irving City Council approved a contract for the construction of Phase 4 of the Delaware Creek Basin drainage channel improvement project. With an estimated completion date of 2021, the contract signals the final leg of the $55 million project.
Since 2016, the City of Irving’s Capital Improvement Program (CIP) has been rebuilding the Delaware Creek Basin drainage channels to accommodate stormwater runoff from increased road, retail and residential development upstream. The project includes expanding and improving existing drainage channels, adding fencing along channel walls and installing wastewater main upgrades.
The city completed work on Phase 1, Delaware Creek from Grauwyler Road to Cripple Creek Drive and Embassy Channel from Delaware Creek to State Highway 183, in October 2017. Phase 2, Brockbank Channel from Grauwyler Road to State Highway 183, was finished in May 2018.
Currently, Phase 3, Delaware Creek from MacArthur Boulevard to Lively Park and Brockbank Channel from Grauwyler Road to Lively Park, is under construction and is slated for completion in 2020. This phase will protect 42 structures along the channel. Phase 3 also includes a redesign of a portion of the wall system, which will save more than 40 trees that would otherwise have been removed with the original design.
Construction on Phase 4: Delaware Creek from Cripple Creek Drive to State Highway 183 will protect 108 structures along the channel. Additionally, the project will replace six road bridges within the area.
The goal of these drainage channel improvements is to protect a total of 229 structures south of State Highway 183, as well as 10 bridges, from a 100-year flood plain. The program is intended to reduce floodplain limits in Irving and protect public and private property.
These projects, along with the new drainage crossings constructed as part of the Midtown Express project, will enable the city to one day provide additional flood protection to another 320 structures north of State Highway 183.
