Harris County's flood district called the Kingwood Diversion Ditch fully funded in March. Thursday it asks the court for $5 million more.

Harris County’s Flood Control District told a river authority board in March that the Kingwood Diversion Ditch was fully funded through construction. On Thursday it asks Commissioners Court to take a $5 million state grant for the project’s first construction phase.

Why it matters

This ditch is the project meant to carry water past Kingwood. Its published cost has moved by about $11.5 million in two years, and the district’s own project page publishes no cost at all.

A project that is fully funded does not need a first construction phase paid for by somebody else. One of those two statements is wrong, and residents are owed which.

By the numbers

$5,000,000, the Texas Water Development Board grant. The board’s own item puts it at the January 22, 2026 meeting as project 21903, under Senate Bill 1 of the 89th Legislature, Article IX, Section 17.18(18). The applicant is the Harris County Flood Control District.
Still in design, the project status in that same state document, which also says the district plans to spend the grant on the first construction phase of the channel modifications.
$54.5 million, the construction cost the district put on its recommended design at a March 6, 2024 community meeting, per Community Impact.
About $43 million, the figure the district’s then executive director gave the San Jacinto River Authority board on March 26, 2026, per Reduce Flooding, which reported she called the project fully funded through construction.
$11.5 million, the gap between those two published costs, about 21 percent lower. This desk’s arithmetic.
About 12 percent, the grant against $43 million, or about 9 percent of $54.5 million.
$3.5 million was the design money named in 2024: $1.9 million from the 2018 bond program and a $1.6 million EPA grant carrying a $500,000 local share, spendable only on design. Construction had no allocated funding then.
44 Flood Control District items sit on the October 15 agenda, per Reduce Flooding, which puts the grant at item 432. The agenda text this desk could read runs through item 305, so that number is not confirmed here.

What the coverage buried

Reduce Flooding is the only outlet carrying this item. Bob Rehak’s account names the grant, the state program, the legislator who secured it and the item number, and says plainly that $5 million will not come close to funding the project.

What it does not do is set that next to the district’s March statement that the project was already funded through construction, which the same site reported in March. Two sentences seven months apart on one website, and they do not agree.

The deeper gap is upstream. The district’s own F-14 page describes the work and publishes no cost, no funding source, no schedule and no status. Every figure above came from a state board document, a 2024 account of a community meeting, or one local writer’s notes. None came from the agency spending the money.

The other side

A grant is money arriving, not money leaving, and taking $5 million of state funds for a project in the pipeline is what a competent district does. “Fully funded through construction” can also be literally true if the funding plan already counted this grant, authorized in January, two months before the March statement. That is the likeliest explanation.

If so, the funding plan is a document, and nobody has published it. The state’s own January item says the project was still in design, which is not funded through construction. Either reading leaves a $43 million number nobody can trace.

What to watch

October 15, 9 a.m., 1001 Preston. Whether the court takes the grant, and whether anyone asks how a fully funded project needed it.
April 2027, the construction start the district gave in March, and the end of 2027, the completion date it gave with it.
The district’s F-14 project page, which could carry a cost, a funding breakdown and a schedule tomorrow.

Bottom line

The grant is good news for Kingwood. The arithmetic around it is not. A project costed at $54.5 million in 2024 and about $43 million in 2026, called fully funded in March, is taking state money in October for its first construction phase. Thursday is the day to ask which figure is real.
