F-03 Dagg Stormwater Detention Basin

The Dagg Stormwater Detention Basin (HCFCD Unit A500-08-00) will help reduce flooding risks in the Clear Creek watershed by storing excess floodwater during times of heavy rain, and releasing it back to the creek when the threat of flooding has passed. The basin will be located on an approximately 22-acre site near the intersection of Cullen Boulevard and the Sam Houston Tollway, just north of Christia V. Adair Park.

A preliminary engineering report completed in September 2018 evaluated alternatives for the basin, which is proposed at the site of a former sand pit purchased by the Flood Control District in 2017.  The report recommended construction of a basin with a permanent pool that will hold approximately 188 acre-feet of stormwater and include features to improve stormwater quality.

A Community Engagement Meeting was held for this project on May 30, 2019.

The Flood Control District is coordinating plans for the basin with Harris County Commissioner Precinct 1, which manages Adair Park. The project complements but is separate from the Clear Creek Federal Project.

  • This project is a “Local Only” bond project, which means there is no other funding partner at this time and total project costs would be paid with bond funding.
  • Total allocation for this multi-stage project is currently $7.4 million on the Bond Project List.
