TxDOT, the Lake Houston Redevelopment Authority (LHRA), City of Houston and Tax Increment Redevelopment Zone (TIRZ) 10 will solicit public comments at a Northpark Phase II Input Meeting, from 5-7PM Thursday, March 7 at the Kingwood Community Center.
A significant part of the effort to provide an all-weather evacuation route from Kingwood in the event of another superstorm, such as Hurricane Harvey.
Current Northpark Drive looking west toward 59. Major crossroad in center of frame is Woodland Hills Drive. Extent of project would go from bottom of frame to treeless area in distance.
Phase II will run from slightly west of the Kingwood Diversion Ditch to slightly east of Woodland Hills Drive. Part of the mile-long project falls in Montgomery County and part in Harris County.
Purpose of Project
The purpose of the project is to address current and increasing traffic congestion. Utility and drainage features will also be upgraded.
And to improve safety for bicyclists and pedestrians, the project will include a new pedestrian underpass and 10-foot wide sidewalks that connect to the Kingwood trail system.
The TxDOT announcement provides a few of the details:
To improve commute times, the roadway will expand to three lanes in each direction and include turn lanes.
To improve safety, lane width will also increase.
The proposed reconstruction will include new signals at the Woodland Hills Drive and Hidden Pines Drive.
To improve drainage and make Northpark passable in high water events so Kingwood residents have an all-weather evacuation route.
No Home Or Business Structures Expected to be Impacted at This Time
TxDOT does not anticipate impacting any home or business structures at this time. But strips of property that front on the roadway will need to be acquired. For additional details, see this TxDOT page or a schematic drawing on this LHRA page.
Meeting Details
LHRA and TxDOT will discuss plans for the next phase of the project. It will reach past Woodland Hills Drive.
Thursday, March 7, 2024 from 5-7 p.m. Kingwood Park Community Center 4102 Rustic Woods Dr. Kingwood, TX 77345
Part of Northpark Phase II
The Northpark Expansion project will not only move traffic faster, it will create an all-weather evacuation route for 78,000 people in the Kingwood and Porter areas. During Harvey, other evacuation routes were cut off.
Pictures of Major Features
The pictures below show the way things exist now. Captions will describe the changes.
West is Up. Note Walgreens on south side of NP (top left) and Exxon on north side (top right).Three lanes of traffic will continue outbound and continue past bottom of frame inbound. Turning lanes widened and added.Pedestrian underpass will be added between the Walmart Parking Lot (right) on the north and McDonalds/Executive Barber Shop (shown on the left). Road will be elevated as over other underpasses in Kingwood.
The underpass will improve safety for thousands of Kingwood Park High School, Kingwood Montessori, Creativity Shell, and Village Learning Center students.
Looking W along Northpark. Elevated roadway and new bridges over Bens Branch by St. Martha’s (upper right out of frame) will improve safety during high water events.
In addition, the road will be widened to at least three lanes, from US59 until approximately 1,000 feet east of Woodland Hills Drive.
Who Should Attend?
Any whose evacuation route was cut off during Harvey
Anyone who commutes along Northpark
Parents of Kingwood Park High School Students
Business owners in the Northpark Place Commercial Association
Anyone who flooded along Northpark, North Woodland Hills
Anyone who flooded downstream because of Bens Branch
Anyone who flooded along the Kingwood Diversion Ditch.
That’s because Northpark drainage is intricately connected with Diversion Ditch and Bens Branch Drainage.
Your input is vital to ensure the project remains consistent with your needs and community norms.
Please come. Speak now or forever hold your peace, as they say in wedding ceremonies. Many will to have to live with this project for the rest of their lives.
In the past two weeks, construction activity for the Northpark expansion project has focused primarily on the ponds at US59 that will double as detention basins.
However, progress has also been made farther east. CenterPoint has been busy relocating gas lines. Contractors now have signed right-of-entry permits to UnionPacific (UP) property. And they have been busy installing a storm-sewer junction box in front of the Shell Station at Loop 494.
But the thing most people will notice this week is that two of the four outbound lanes on Northpark at 59 are now closed and will remain that way for several months.
Entry Ponds
I took all the pictures below during the last week of February 2024. For the first time, you can clearly see the outlines of both ponds. Contractors started on the north pond first. So, it is further along. But the outline of the south pond, ringed by transplanted trees, is now also clearly visible.
Looking N at S PondCloser shot shows three more decorative areas for plantings, one on each side of the triangle.Men working on foundation for retaining wall around one of the landscaping areasalong Northpark Drive.Reverse angle. Looking S at N pond.Retaining wall around area to be landscaped was just completed and contractors were removing forms for concrete.Pipe for storm drains is being stockpiled in North Pond.
As you can see from these photos, the sides of the ponds will slope toward the middle. Maximum depth for each pond will be about 20 feet.
According to Northpark Expansion Project Manager Ralph De Leon, excavation currently is down to about 7 feet max, the approximate location of the water table. So, the ponds will eventually get almost three times deeper than they are now. That’s a lot of dirt to move!
Contractors will use the dirt to fill in over the box culverts which will go down the center of Northpark. But because of several utility conflicts, placement of the box culverts had to be put on hold.
So, contractors are storing the dirt at the Eagle Sorters Sand Mine on the West Fork. It will be transported back to Northpark when needed.
Stored dirt (center) from entry ponds at the Eagle Mine on Sorters-McClellan Road.
Once contractors place the dirt over the culverts, they can then begin paving two additional lanes of traffic over where the center ditch used to be.
UnionPacific
Now that all the legal agreements are in place and engineering plans have been approved, work can begin around the UP tracks. It won’t happen immediately though. According to UP, rail traffic is now in its peak season. In the coming months, expect to see three types of activity.
Boring under the tracks to take excess stormwater from the entry ponds to the Kingwood Diversion Ditch and Bens Branch via Ditch One.
Placement of a one-piece concrete bed/continuous section of track over the project area with signal upgrades
Creation of ground-level feeder roads/turn lanes on each side of main lanes which will bridge over the tracks.
Looking E at Ditch One, Part of Northpark Expansion Drainage. Northpark is in upper right.
Northpark Expansion Project Lane Closures
Starting yesterday, 2/26/24, two westbound lanes on Northpark at 59 closed temporarily for reconstruction during the next few months.
During the first month, the existing left turn lane and one through lane will remain open. Then traffic will switch onto the newly constructed lanes, while the other lanes are completed. The contractor will install new storm sewer pipes and inlets along with new concrete roadway.
Looking N. Demolition has already begun on two westbound lanes.At 4 PM on Tuesday afternoon, OUTBOUND traffic on northpark was backed up past Russell-Palmer Road because of the lane closures.
Westbound traffic should expect delays and alternative routes are encouraged.
Judging by the outbound delay I saw today, I plan to avoid this bottleneck for the duration of the Northpark Expansion project.
Other Activity
The Lake Houston Redevelopment Authority (LHRA) and City Councilmember Fred Flickinger are scheduled to meet with the City Attorney on Thursday, 2/29/24, to discuss the Entergy issue. After years of discussion, the utility has not yet begun moving its power lines and transformer out of the way.
LHRA will hold a board meeting on March 14th, in part, to discuss Entergy options.
On Friday, March 15, the City, LHRA and Entergy will meet. Hopefully, they will come to an agreement that doesn’t involve legal action, which could increase costs and cause delays.
Reminder: Phase II Meeting on March 7
Also don’t forget the public input session on March 7 from 5-7 PM. LHRA and TxDOT will discuss plans for the next phase of the project. It will reach past Woodland Hills Drive.

Harris County Engineering has released preliminary drainage plans and a drainage analysis in response to a FOIA Request for a new Kings River Development located along Kings Park Way and Pinehurst Trail Drive. The drainage analysis claims “no adverse impact” on surrounding neighborhoods because of the three detention ponds they plan to build.
But the analysis by R.G. Miller Engineers, which is now under review by Harris County Engineering:
Omits data
Contains misstatements
Leaves out related reports
Includes alarming assumptions.
Together, these issues call into question the conclusion of no adverse impact.
In the meantime, the clearing of the Phase-1 site, owned by Meritage Homes, continues, even though Harris County disapproved construction plans for its detention basin.
Looking W.Mertitage Kings River Phase I construction site was about 80% cleared as of 1/29/24 at noon.
Let’s look at each of the issues above.
Data Omitted
Typically, engineers justify “no adverse impact” by comparing pre- and post-development peak-discharge rates. If the post- rate does not exceed the pre- rate, then they claim “no adverse impact.”
But the drainage analysis does not show the pre-/post comparison in a simple table. Why?
Take Tables 7 and 8A, for instance. They address calculations involving Pond 1 on the first section of land now being cleared (see above).
Table 7 from R.G. Miller Drainage Analysis, Page 7. Note blank boxes top leftafter Existing Peak Discharge.
The data is missing. They omitted the data again in another series of tables later in the analysis.
Drainage Analysis Table 8a, Page 13. Note missing data after “Maximum Allowable Outflow,” line 6.
A third table (1-D, page 8) includes pre-development runoff for all three ponds. Together, they seem to justify the claim.
But I can’t find the peak runoff for Pond 1 by itself in any one of the pre/post comparisons. Keep in mind that the second two ponds won’t be built for years. In the meantime, Pond 1 will be the sole source of mitigation.
Soil Analysis and Environmental Reports Not Completed
Discharge rates also depend on soil types. That’s because the soil on a site affects the rate of infiltration.
But Section 10 on Page 15 of the drainage analysis talks about how a geotechnical report (which would determine infiltration rates) has not yet been produced. It says, “…a geotechnical investigation is required to characterize potential soil conditions.”
The drainage analysis also never mentions the wetlands on the property. Those would normally be addressed in an “Environmental Issues” section. But that section says only, “Environmental investigation has not been completed in this study.”
This is kind of like your jet taking off without a full load of fuel. You might get to your destination, but…
Misstatement?
The report also contains a huge misstatement.
For instance, Section 2.2.3 (Results) begins with, “The detention storage volume required for the proposed 41.5 acres residential development is 26.98 acre-feet per acre.” That would mean they require 11,196.7 acre-feet of detention. But they’re providing only 39.8 acre-feet of storage volume.
I’m sure this is a typo. Another section of the analysis later states that the 26.98 figure is computed by using Harris County’s minimum requirement of .65 acre-feet per acre.
Such misstatements and poor proofing call into question other calculations in the analysis.
Alarming Assumption
Section 2.1 (Existing Conditions) states, “Since the proposed detention ponds outfall to an existing 30-in RCP and 36-inch RCP at Pinehurst Trail Drive, the maximum allowable discharge in this study will be the maximum capacity of the 30-inch RCP and 36-inch RCP.”
That sounds to me as though they feel they can use 100% of the existing storm sewer capacity…without regard to the needs of surrounding neighborhoods. For instance, assume that surrounding neighborhoods already use 75% of existing capacity. If the new development uses 100%, that means the drains would be 75% over capacity.
No Clear Support for Claim of “No Adverse Impact”
Although, they claim “no adverse impact,” it’s not clear to a lay person how they arrived at that assumption.
In fairness this report is still under review by Harris County Engineering.
The development also sits in the City of Houston’s extra territorial jurisdiction.
I hope both entities make the engineers clarify the basis for their claims and produce a final report that the public can understand. I stared at these 47 pages all day and still don’t understand how they can justify “No adverse impacts.”
Is it too much to ask for clarity when the safety of people and their homes is at stake?
Construction Plan of Detention Basins “Disapproved”
Evidently Harris County Engineering had some concerns with this development, too.
On 2/9/24, Engineering disapproved the R.G. Miller construction plans for Detention Basin #1. Engineering kicked the plans back for housekeeping-type issues.
For instance, the plans didn’t contain:
ID of the channel the ponds drained into
A Project name
A Project number
The signature and seal of a registered Texas professional engineer (PE).
Harris County used to refuse to review plans that weren’t signed and sealed by a PE. I am told that such gratuitous omissions make reviewers angry.
I would link to all the construction plans here. But the file sizes are massive and the construction plans moot for now. More later when/if they’re approved. For now, to review the entire 45-page, 16 meg drainage analysis, click here .
