About a half block west of Kingwood High School, G-103-36-03, a small drainage ditch without a name, cuts under Kingwood Drive. More than a hundred homes near this ditch flooded during Harvey. Before Imelda, Harris County Flood Control District did an emergency “de-snag” on the ditch. That means they cleaned out fallen trees that were forming “beaver dams” and backing water up.
But the right of way under Kingwood Drive has remained about half blocked by sediment. That’s what those red warning signs represent in the picture below. Clearing the right of way is the City of Houston’s responsibility.
When I clicked on the upper warning sign, I found a link to this image from 2019.
Pictures Taken Today Show Same Blockages
I’ve brought this issue to the attention of Mayor Pro Tem Dave Martin and his staff. I’m confident this was just an oversight and look forward to doing another positive story when they complete this job, too.

After finishing excavating silt from under the Kingwood Drive Bridge over Ben’s Branch, City crews are now doing the same under the bridge over the Diversion Ditch near the fire station on Kingwood Drive.
Bridges are often chokepoints during floods because of their supports that reduce and sometimes slow the flow of water and contribute to sediment buildup.
The City of Houston is responsible for excavation under the bridges because the bridges are City property.
On Ben’s Branch, Harris County Flood Control District (HCFCD) had excavated both north and south of the bridge at Kingwood Drive. Then the City did its part.
Pictures of Work in Progress At Kingwood Drive.
However, at the Diversion Ditch Bridge, HCFCD has not yet begun excavation. CoH went first.
Dan Monks, a Kingwood resident, captured work in progress last week and gave ReduceFlooding.com permission to use his photos.
For more than a year, HCFCD has excavated Ben’s Branch in four different phases. However, significant sediment remained under the Kingwood Drive Bridge. That’s property owned and maintained by the City of Houston. And now they are excavating that to eliminate a bottleneck. Such bottlenecks can back water up, damaging homes and businesses.
According to Sarman, who talked with the construction manager, after the crew completes work here, it will remove sediment from the bottleneck at the Kingwood Diversion Ditch next to the fire station on Kingwood Drive.
These are little things that make a big difference to people who previously flooded. And there were plenty of them along Ben’s Branch, especially in the Town Center Area. Some businesses still haven’t recovered. The shopping center north of these photos is still largely vacant thanks to catastrophic flooding during Harvey and a ditch whose conveyance was severely reduced, in part, by bottlenecks like this one.
Thanks go to Mayor Pro Tem Dave Martin and his staff at the District E council office.

Last week, Harris County Flood Control District (HCFCD) began mobilizing for the restoration of the Ben’s Branch drainage ditch between Kingwood Drive and Rocky Woods. The work will involve removing accumulated sediment that has diminished the conveyance capacity of the ditch.
Engineers measure conveyance in terms of “level of service.” A 100-year level of service means that a ditch will convey a 100-year rain without overflowing. The Kingwood Drainage Analysis performed last year by HCFCD revealed that sediment had reduced the conveyance of Ben’s Branch to a 2-year level of service in places. This project will restore the ditch to its original contours.
Importance of Project
Along Ben’s Branch, as a result of flooding during Harvey:
Kingwood High School immediately to the west of this project flooded badly. The building suffered $67 million in damages. The school lost another $10 million in contents. Four thousand students had to be bused to another school for seven months.
Homes along both sides of the ditch flooded.
All four shopping centers in Kingwood’s Town Center flooded. Many businesses still have not returned.
Thirteen people died, included twelve seniors at Kingwood Village Estates. Six died from injuries sustained during evacuation and six from stress-related illnesses after returning and finding their homes destroyed.
History of Previous Ben’s Branch Projects since Harvey
For the current work between Kingwood Drive and Rocky Woods, HCFCD will start at the downstream end and work its way north. The work should take about five months. It involves removing more than 22,000 cubic yards of sediment, restoring the original banks of the ditch, and replacing a number of outfall pipes that have become blocked or damaged over time.
Once the work begins in earnest, HCFCD contractors will enter the northern side of the project at the end of Cedar Knolls and move south toward Kingwood Drive. There, they will exit the project behind the old H-E-B store. Crews will work around Kingwood High School start/stop times to reduce traffic snarls.
HCFCD considers this a maintenance project, not a capital-improvement project.
Expansion of the Diversion Ditch that runs from the new St. Martha Church down to Deer Ridge and River Grove Parks where it eventually enters the West Fork. The purpose of the Diversion Ditch project: to further reduce the flow of water into Ben’s Branch.
A project to reduce flooding along Taylor Gully. Two options have been discussed:
Widening and deepening Taylor Gully itself
Establishing a regional detention pond on the land owned by Perry Homes’ subsidiary Figure Four Partners.
HCFCD has not announced a timetable yet for either of those projects. Any work on Taylor Gully would depend on whether Harris County and the City are able to negotiate the purchase of Woodridge Village from Perry. Woodridge Village is the aborted development that twice flooded Elm Grove and North Kingwood Forest Villages in 2019.

Chris Bloch, an engineer and Kingwood resident, has become a flood-control activist in his retirement. I often run into Chris inspecting ditches, streams and culverts for blockages and collapsed outfalls. Chris also works with the Bear Branch Trail Association which owns property along many of the channels and streams cutting through Kings Forest, Bear Branch, and Hunters Ridge.
For the last several months, Chris has focused intensely on blocked channels that contributed to the flooding of 110 homes in Kings Forest during Harvey. Where the channels cross under Kingwood Drive, three had become almost totally blocked by vegetation and silt. That contributed to backing water up into homes. See below.
Chris meticulously photographed the problems, began researching which entities were responsible for which portions of the channels, and in the case above, contacted the City of Houston. The City has responsibility for the medians and sides of Kingwood Drive and other streets. His persistence paid off.
In October, the City began cleaning out the ditch near Shady Run and Kingwood Drive.
Here’s what that part of the channel looks like today.
Chris is tenacious, tireless, and wide ranging. He looks at ditches from end to end. In this case, he’s also trying to get the Flood Control District to escalate clean-out of the ditch south of Kingwood Drive. Reduced conveyance through that reach could also have contributed to flooding in Kingwood Lakes.
Bloch says he has also identified twenty storm-drain outfalls that need repair. “It doesn’t make any difference if the storm sewers are clear if the water in them can’t get to ditches and streams,” he says.
You Be an Activist, Too
Activists like Chris make Kingwood the great place it is. They help identify local problems for government and make the case for addressing them.
As you hike through our greenbelts and along channels, keep your eyes open for developing problems:
Collapsed outfalls into ditches
Vegetation and silt blocking culverts
Fallen trees damming streams
Be an activist like Chris. Take pictures and report them to the appropriate authorities. That will usually be the City or Flood Control.
You, too, can make a difference.

City of Houston Mayor Pro Tem Dave Martin announced this afternoon that the Texas Department of Transportation (TxDOT) will close the intersection of Kingwood Drive and Texas Loop 494 this weekend. The closure starts Friday evening, April 17 and, weather permitting, will last through early Monday morning, April 20.
Purpose of Closure
This is a bit off topic for a flood blog, but Kingwood Drive affects half my readers and 494 affects many more. Here’s what’s happening.
TxDOT will raise the intersection of Kingwood Drive and 494 with two feet of asphalt. The purpose: to remove the dip by the UP railroad tracks.
Weather permitting, construction should start at 9:00 p.m. on Friday. Crews will work continuously until 5:00 a.m. Monday.
Please watch for flagmen and orange traffic cones indicating detours. Detours at Crescent Springs, Butterfly Lane, Royal Forest and Northpark Drive are shown below.
For more information, contact TxDOT at (936) 538-3300.
