Editor's note: The story has been updated to clarify the cost of the four basins and future unfunded phases. The Harris County Flood Control District's project website has been reworded to make this more clear.

Katy-area residents can attend a virtual community engagement meeting Feb. 27, where they can learn more about a series of stormwater detention basins that will be built near the Grand Parkway.

In a nutshell

Harris County Flood Control District staff aim for the Clay Stormwater Detention Basin to capture stormwater during rain events and decrease flood risk in the surrounding and downstream neighborhoods, HCFCD officials said in an email. The $9.4 million project will create four detention basins along South Mayde Creek near the intersection of the Grand Parkway and Clay Road.

“​​While the surrounding areas will see a reduction in flood risk as a result of this project, the largest benefits will be seen in the neighborhoods downstream of the project, including Westlake Place, Westlake Forest and Sundown Glen, and roadway crossings at Clay Road, Raintree Village and Greenhouse Road,” officials said in an email.


The details

According to a HCFCD news release, the purpose of the virtual meeting is for:
  • Community members to get information on the project’s status
  • HCFCD staff to share updated project information as the preliminary engineering stage concludes
  • HCFCD staff to gather community input on the project
The virtual meeting will take place from 6:30-7:30 p.m. on Feb. 27, and attendees can join via the online link or phone at 855-925-2801 with meeting code 2397, according to the release.

What’s next

A future phase will add detention east of the Grand Parkway at an additional cost of $84.6 million, but the phase is unfunded and would require partnership funding, HCFCD Communications Specialist Herman Sanders said.


HCFCD officials said they plan to begin the Clay Stormwater Detention Basin project in the third quarter of 2024, with construction lasting roughly one year.
