9/16/24 – As promised, contractors began the first Northpark concrete pour for a major stretch of the road expansion project this morning. They scheduled the pour for 3 AM to 1 PM. And by 9:30 AM they appeared on schedule to finish the first 1,000 feet within the allotted time. See the pics below, all taken on 9/16/24.

After this first Northpark concrete pour, we should see three more by October 1. See the plan here.
More Visible Progress, Next Stages
According to project manager Ralph De Leon, the underground drainage and utility work is the hardest and slowest part of the project. “So, residents will see much faster progress now,” he said.
Northpark expansion will accommodate population growth and speed up traffic. But it will also create an all-weather evacuation route for 78,000 Kingwood residents.
The center ditch that used to go down Northpark has now been totally replaced with box culverts. Now contractors are paving over the culverts.
The old lanes will be demolished and replaced by new concrete also.
After Northpark is paved from Russell Palmer Road to Loop 494, the focus will shift to repaving a portion of 494 and then the commercial strip between 494 and the entry ponds at US59.
To help the public plan around construction, the Lake Houston Redevelopment Authority constantly updates its project page with a three-week “look-ahead” schedule.

Recommendations in the San Jacinto River Basin alone (Region 6) total 519. And they’re buried within the larger spreadsheet, making it difficult summarize and compare them, much less see how the money is being distributed locally.
State Flood Plan Costs Staggering
The costs of the state flood plan are staggering. If all projects were implemented statewide tomorrow, they would cost more than $54 billion in 2024 dollars. Those in the San Jacinto Basin would total almost $10 billion.
Three Categories of Recommendations
Recommendations fall into three categories: Evaluations (engineering studies that lay the groundwork for future construction projects); Flood-Mitigation Projects (construction); and Strategies (buyouts, elevations, etc.)
The table below shows the breakdown. Region 6 (the San Jacinto Watershed) contains a lower percentage of flood mitigation projects and higher percentages of Evaluations and Strategies than the rest of the state, which is broken down into 15 regions.
I’m still analyzing all these entries. But already several things have jumped out at me from the standpoint of a Lake Houston Area resident.
Most of our stormwater comes from Montgomery County. But in the Evaluation list, Harris County projects outnumber those in Montgomery County by more than 5 to 1.
And most of the projects in Montgomery County tend to be limited in scope. For instance, Conroe has entries for a downtown master drainage plan, an Avenue M drainage plan, a South 3rd drainage plan and more.
Conroe also broke out separate projects for developing benefit-cost analyses associated with such projects and subdivision drainage projects.
Harris County and Galveston County, on the other hand, tended to look at things from a watershed-wide point of view.
Projects
The state flood plan lists only 69 flood-mitigation construction projects in all of the San Jacinto River Basin. And of those, only eight are upstream of Lake Houston. One is already a non-starter. The land for a detention basin on Spring Creek has already been sold for commercial development.
The remaining seven projects with their priority ranks include:
Caney Creek channel improvements and detention (#52)
Widening the West Fork and shaving down its flood plains (#67)
Peach Creek channel improvements and detention (#72)
Building a 1.6 mile earthen embankment to capture runoff from Winters Bayou in the East Fork watershed far upstream in San Jacinto County (#82).
Lake Creek Detention in Montgomery County (#105)
Improvements to the Kingwood Diversion Ditch (#144)
Cypress Creek detention (#149)
Strategies
It’s hard to see how any of the 654 strategies listed for the San Jacinto Basin would help the Lake Houston Area. Some might keep flooding from getting worse.
For instance:
Coastal Prairie Conservancy proposed a project to conserve more than 1,000 acres in the headwaters of Cypress Creek.
Harris County Flood Control proposed money for buyouts and relocations.
Missing: SJRA, Payment Plan, Integration
Strangely, the 147 pages of 3 point type in the state flood plan make no reference to the San Jacinto River Authority or SJRA.
Yet, as we saw in Harvey and again last May, the SJRA has huge gaps in its monitoring network upstream from Lake Conroe. During floods, these gaps make it difficult to assess how much water is moving toward the dam.
So dam operators tend to err on the side of caution and release more water than they may need to. In May, this contributed to the flooding of hundreds of structures downstream from the dam. To me, more gages would have been an important addition to the list.
It’s also not clear how Texas will pay for all these projects.
But let’s assume it’s a billion dollars. If the legislature voted that every other year, it would take at least a century to build all these projects with inflation factored in.
Finally, it’s not clear how all these projects work together to reduce flood risk, though many mention that they should only be considered after other projects.
Hey, it ain’t perfect. But you have to start somewhere!

9/14/24 – Clearing of Beryl debris from Harris County creeks and channels by HCFCD/FEMA contractors continues more than two months after the storm that struck Houston on July 8, 2024.
The cleanup effort has advanced on two fronts: streets and channels. The City of Houston and Harris County precincts (in unincorporated areas) manage street cleanup. Harris County Flood Control District manages the creeks and channels.
I previously reported about the City’s efforts and its debris-tracker website. I also published a story about how to report problems discovered in streams and ditches.
But I really haven’t shown the latter crews in action.
HCFCD/FEMA Crew Clearing Backland Gully
Chris Bloch, a local flood activist, rode along with some Harris County Flood Control Distict/FEMA contractors and grabbed these photos of the equipment they are using. Bloch took the pictures below on Backland Gully in Kings Point.
A marsh buggy, also known as an amphibious excavator, grabs onto tree blocking the channel and……drags it out of creek.
The contractor is clearing trees from numerous channels in the Kingwood Area. His company is also working Bens Branch, Bear Branch, the lowest reach of Taylor Gully, White Oak Creek, Green Tree Ditch, Mills Branch, Caney Creek and more.
The contractor estimated his company has removed 2,000 tons of debris so far, but the number changes hourly.
Immensity of Job
Last week, they finished the area upstream of the Tree Lane Bridge on Bear Branch. But the equipment they used there is too small to handle the size and volume of trees that fell downstream from the bridge given the depth of the channel.
They have their work cut out for them.
See examples below. I took all six photos on 9/13/24 within a quarter mile stretch of Bens Branch downstream from Tree Lane.
Such blockages can catch other debris being swept downstream in storms and back water up, flooding homes.
HCFCD maintains 2500 miles of ditches, bayous and streams. If a quarter mile segment of one looks this bad, one can only imagine how long it will take to finish the job.

San Jacinto River Basin Recommendations in State Flood Plan
The new Texas state flood plan contains approximately 4351 recommendations in 15 regions statewide. The spreadsheet runs 147 pages in 3-point type. An eagle would have trouble seeing this type!
Recommendations in the San Jacinto River Basin alone (Region 6) total 519. And they’re buried within the larger spreadsheet, making it difficult summarize and compare them, much less see how the money is being distributed locally.

Currently, the flood infrastructure fund dashboard is down. So there’s no telling what the fund balance is.

Clearing of Beryl Debris from Creeks and Channels Continues
9/14/24 – Clearing of Beryl debris from Harris County creeks and channels by HCFCD/FEMA contractors continues more than two months after the storm that struck Houston on July 8, 2024.
Prolonged 65-80 MPH winds raked the Lake Houston Area for hours, downing thousands of trees.
Who’s Responsible for What
The cleanup effort has advanced on two fronts: streets and channels. The City of Houston and Harris County precincts (in unincorporated areas) manage street cleanup. Harris County Flood Control District manages the creeks and channels.
I previously reported about the City’s efforts and its debris-tracker website. I also published a story about how to report problems discovered in streams and ditches.
