Harris County Commissioners Court will consider approving a $5 million grant agreement with the Texas Water Development Board to fund Kingwood Diversion Ditch improvements when it meets Thursday, October 15. The item appears on the published agenda as item 432, a Harris County Flood Control District request covering work in the San Jacinto River watershed in Precinct 3.
The agenda lists the project under Bond ID F-14 and Project ID G103-38-00-E001, with the state grant recorded as Agreement No. 2026-108. The court meets at 9 a.m. at 1001 Preston Street in downtown Houston, and the meeting is also carried by livestream.
The Kingwood Diversion Ditch carries stormwater away from Bens Branch, which runs through the middle of Kingwood. Drainage capacity in that channel system is one of the long running flood questions in the neighborhood, so a funding item for it is a direct local matter rather than a countywide one.
It is one of eight state flood grants on the same agenda
Items 432 through 439 are all Flood Control District requests to approve Texas Water Development Board grant agreements. Together they total $75 million across seven watersheds:
| Item | Amount | Project | Watershed |
|---|---|---|---|
| 432 | $5,000,000 | Kingwood Diversion Ditch improvements | San Jacinto River |
| 433 | $6,500,000 | West Little York stormwater detention basin | Addicks Reservoir |
| 434 | $22,500,000 | Erosion and sediment repairs on main stem Cypress Creek | Cypress Creek |
| 435 | $2,500,000 | Halls Aldine Westfield South detention basin and channel work | Halls Bayou |
| 436 | $10,000,000 | South Mayde Creek bypass channel | Addicks Reservoir |
| 437 | $11,000,000 | Cloverleaf area drainage improvements | Carpenters Bayou |
| 438 | $15,000,000 | Helms detention basin and channel conveyance | Halls Bayou |
| 439 | $2,500,000 | Channel modification and detention on middle Greens Bayou | Greens Bayou |
The Kingwood grant is the only one of the eight in the San Jacinto River watershed, which is the watershed that drains the Lake Houston area.
What the agenda does and does not settle
An agenda item is a request for approval, not an approval. The court has not voted, and these figures are what the Flood Control District has asked the court to accept from the state rather than a construction budget or a schedule. The $5 million is a state grant toward the project and is not the full cost of the work.
The local flooding site ReduceFlooding, which reports on drainage in the Lake Houston area, flagged the Kingwood item ahead of the meeting and has reported previously on the project’s scope and estimated cost. Those cost and timeline figures come from a March 2026 presentation to the San Jacinto River Authority board and are not part of Thursday’s agenda item, so they are not repeated here as current numbers.
Also on Thursday’s agenda, and covered separately: the county’s accounting of its license plate cameras. Related: the Flood Control District’s next phase at the T.C. Jester detention basin and why a weaker hurricane can still be the one that floods.
