Montgomery County Development Regs Revised, New Drainage Criteria on Hold

3/14/25 – Montgomery County Development Regs have been revised and became effective on 3/4/25.

The MoCo Engineer has posted them online. For convenience, I have also posted them under the Regulations Tab on the ReduceFlooding Reports Page.

The primary audience for the regulations is developers. However, neighbors near new developments may wish to study the regs, too, to ensure developers follow the rules.

On a separate but related note, MoCo’s new Drainage Criteria Manual is still on hold.

Changes

Montgomery County Subdivision Regulations were adopted in 1984 with an update in 2021. This rewrite includes many significant updates, such as:

  • Privacy fences at least 6-feet high between new commercial developments and existing single-family homes.
  • An entire section related to Traffic Engineering Study requirements.
  • Planting requirements along curbs
  • A new minimum lot width standard of 40′ for concrete curb and gutter and 65′ for asphalt open ditch lots
  • Commercial Drainage Plans will now be reviewed before acceptance of the entire permit submittal
  • A modified “impervious cover” threshold
  • New requirements for Stormwater Pollution Protection Plans.

What Developers Must Submit

Section Three outlines what developers must submit to Commissioners’ offices. This could come in handy if you ever need to submit a FOIA request. Requirements include:

  • Timelines
  • Maps
  • Construction traffic routing/access points
  • Drainage Reports and Studies
  • Spreadsheets used in calculations contained in those reports
  • Construction Plans including a Drainage Impact Analysis

Separate plans must be prepared for each subdivision.

Section 4 covers drainage plan requirements. Among other things, a drainage plan must provide for the disposition of runoff entering the development from adjacent property, runoff within the development and runoff leaving the development to an acceptable outfall.

Floodplain and Floodway Development

Section 5 specifies additional requirements for drainage studies when developers build in floodplains and floodways. For instance, they must obtain a Conditional Letter of Map Revision (CLOMR) from FEMA prior to the County’s approval of a drainage plan or study when:

  • Proposing to construct a detention pond or alter the floodway landscape
  • Relocating a stream
Northpark Woods and West Fork flood risk
If Northpark Woods were being built today, the developer would have to comply with the new development regs because part of it is in the floodplain of the West Fork.

A CLOMR is a FEMA comment on a proposed project that could impact flood-hazard areas. And it indicates whether the project, if built as proposed, would meet National Flood Insurance Program (NFIP) standards and warrant a change to the Flood Insurance Rate Map (FIRM). 

Alteration of a stream or river also requires TCEQ approval and the approval of any governing entities within 1,000 feet.

Status of Updated Drainage Criteria Manual

On a separate note: MoCo will soon update its Drainage Criteria Manual (DCM). The county is still working off an old DCM from 2019 that was a minor revision of a 1989 document.

In February 2024, Montgomery County finally published a draft of a comprehensive new DCM. The draft brought the County’s standards up to date and in line with surrounding areas’. 

Major changes included, but were not limited to:

  • Use of industry-standard modeling software by engineering companies submitting plans
  • A requirement that new developments produce “no adverse impact” on downstream areas
  • Mandates to use certain “roughness coefficient standards” when calculating flood peaks.
  • Stipulations that all projects shall mitigate and attenuate runoff for 5-, 10-, and 100-year storm events
  • Stormwater detention for all developments regardless of size
  • A discussion of flood mitigation measures
  • Identification of entities responsible for maintenance of stormwater detention facilities, channels, etc.
  • Adoption of Atlas-14 rainfall rates
  • A minimum detention rate of .55 acre-feet per acre (almost up to Harris County’s rate)
  • Prohibition of hydrologic-timing surveys (also known as flood-routing or beat-the-peak studies).

I’ll let you know when/if MOCO adopts these new drainage standards.

By the way, people always ask me why I list “days since Harvey,” on all my posts. I want to dramatize how long political change takes. And this is a prime example.

How Wide Will Northpark Be When Done?

3/13/25 – Just how wide will Northpark be when construction is complete? After the UnionPacific Railroad finished installing concrete road crossing panels last week we now have a visual cue. It’s going to be WIDE! With a capital W! Approximately three times wider than it currently is. See the pictures below taken this morning.

Looking E. See concrete panels in railroad tracks.

Northpark will expand from its current four lanes to 10 with two 10-foot-wide sidewalks.

In addition to accommodating extra traffic, one of the main reasons for expanding Northpark is to create an all-weather evacuation route from Kingwood for 78,000 people.

Why So Many Lanes?

The 10 lanes will include:

  • Six lanes over a bridge that spans the tracks and Loop 494. It has yet to be built. The bridge will carry three lanes in each direction.
  • Two surface lanes on the north/outbound side of Northpark will let traffic turn left or right onto Loop 494.
  • Two surface lanes on the south/inbound side of Northpark will let Loop 494 traffic from the north and south turn onto Northpark.
  • Two sidewalks (one on each side of Northpark) will accommodate both pedestrians and bicyclists.
Northpark looking W toward 59. Again, concrete panels in UPRR tracks indicate eventual width of traffic corridor.

Loop 494 Width

Loop 494 will also expand to accommodate more traffic.

Looking North along Loop 494 at Northpark. The old road will expand to 5 lanes, two in each direction plus one dedicated turn lane from each direction.
Looking S at Loop 494 from opposite direction.

The schematic below shows how the intersection will eventually look.

From approved plans.

Elsewhere on Northpark

Between Russell Palmer Road and Loop 494, contractors are making good progress with the drainage that goes under the expanded roadway. On the North/Outbound side, the underground work is almost complete. And this morning, they were stabilizing the road bed.

Stabilizing road bed on outbound Northpark (north side).

At this morning’s Lake Houston Redevelopment Authority/TIRZ 10 Board Meeting, project manager Ralph De Leon stated that contractors would soon bore underneath the railroad tracks. Once they connect the drainage on the east and west sides, they can begin paving. So you should see the pace of progress accelerate soon.

Spreading more road base and compacting it.

On the inbound/south side of Northpark, contractors are also making excellent progress with the drainage after resolving more utility conflicts.

Looking W at inbound side (left). The old concrete has been removed and drainage work is in full swing.
Closer shot of new drainage on inbound Northpark.

Part of Phase II May Be Accelerated

Also at the board meeting this morning, De Leon introduced the idea of moving Phase II stormwater detention work forward. Phase II of Northpark expansion covers the area from Woodland Hills Drive to a block west of the Kingwood Diversion Ditch.

Phase II calls for building a detention basin to compensate for extra runoff caused by the road expansion. Just as the entry ponds at US 59 compensate for much of the extra runoff in Phase I.

De Leon discussed a combination of two types of detention. Together, they could add as much as 100 acre-feet of stormwater detention capacity to the project. They include:

  • In-line detention within the Diversion Ditch itself, down to the first bend south of Northpark.
  • A large, regional detention basin near where the Diversion Ditch and Bens Branch come together.

He stated that, right now, much of the water coming down Bens Branch shoots past the Diversion Ditch. That’s because the Diversion Ditch splits off the main part of Bens Branch at almost 90 degrees.

Diversion Ditch = white. Bens Branch = red.

Partially as a consequence, during Harvey, 100% of the businesses along Bens Branch in Town Center, dozens of homes, and Kingwood High School flooded badly and still have elevated flood risk.

For instance, during Harvey, large parts of Town Center had 4- to 8-feet of water. Moreover, 12 people died at a retirement home in Town Center as a result of evacuation or immediately after it.

A detention basin at the junction of Bens Branch and the Diversion Ditch would slow incoming water down. That would give the stormwater a chance to drain into each channel the way it was originally designed to.

The volume of stormwater detention that De Leon discussed would provide enough to accommodate Phase II, insufficiently mitigated upstream development, future expansion, and part of HCFCD’s plans for the Diversion Ditch.

The community will need it eventually, especially when Northpark Drive bridges over the two channels are raised. The higher roadway will eliminate chokepoints that let more floodwater flow downstream. So, building more detention now could protect people along both channels – and sooner rather than later.

Engineering details are still being worked out. The board took no action on it this morning, nor were they asked to.

NHC Announces Changes to 2025 Hurricane Forecasts

3/12/25 – The National Hurricane Center (NHC) has announced a series of changes to 2025 hurricane forecasts. The changes affect cone graphics, risk maps, prediction periods, forecast uncertainty, and forecast frequency. Let me attempt to summarize and simplify a highly complex announcement.

Experimental Cone Graphic with Depiction of Inland Watches/Warnings

Along with its normal cone graphics, NHC will offer experimental cone graphics that feature inland watches and warnings. The new experimental graphics will now contain diagonal pink and blue lines in areas where hurricane watches and tropical storm warnings are in effect simultaneously.

The current cone graphic that only shows coastal watches and warnings will remain. But research showed that adding inland watches and warnings could help communicate wind risk for those who live away from coasts.

The new, experimental graphics take longer to produce. So, they may appear online up to 30 minutes later than the regular graphics. Here’s an example.

Blue = TS Warning, Red = Hurricane Warning, Yellow = TS Watch, Striped = Simultaneous Hurricane Watch and TS Warning

Rip-Current Risk Maps

An increase in fatalities from rip currents during the past decade prompted this innovation. NHC will compile a national rip current risk map from data provided by local National Weather Service offices. It will cover the current day, the next day, and a composite showing the highest risk for both days. However, it will not contain information on surf height.

For more information on NWS surf zone forecasts, rip current risk categories, and rip current safety, visit https://www.weather.gov/safety/ripcurrent-forecasts.

Earlier Warnings for Potential Tropical Cyclones

NHC will now issue potential tropical cyclone advisories up to 72 before the anticipated arrival of a storm. That’s up from 48 hours for watches and 36 hours for warnings. The longer lead times will give people more time to prepare when there is a high risk of significant damage.

Earlier Forecasts for Hurricane Wind Radii Forecasts

Until now, NHC has issued forecasts of storm widths two days in advance. They will now provide those forecasts three days in advance.

Those same forecasts (which also include wave height), will now show the height in meters instead of feet, based on requests from the public.

The forecast wind radii are available in real-time in a geographic information system (GIS) friendly format at the following link: https://www.nhc.noaa.gov/gis/.

Error-Cone Forecasts

As storm forecasting becomes more accurate, error cones are shrinking. This year’s error cones will be 3-5% smaller than last year’s, based on a 36-hour forecast period. 96-hour cones could shrink as much as 9%.

However, this may fool some people who misunderstand what the cones mean. The cone represents the probable track of the center of a storm, not its width.

A storm’s center has an equal chance of tracking along any point within the cone. If people think the cone indicates a storm’s width, they might be lulled into a false sense of security if they are outside a smaller cone.

Frequency of Watch/Warning Updates

NHC will now issue storm watch/warning updates eight times a day instead of four whenever coastal watches or warnings are already in effect. They actually instituted this change last year. So, this is a reminder. You can check for full updates every three hours.

That’s it for the summary of NHC’s changes to 2025 hurricane forecasts. Here also are some helpful links to use throughout the upcoming hurricane season.

Where to Find NHC Information

Live Stream

NHC will livestream forecast updates simultaneously on YouTube and Facebook whenever an area of interest exists that may pose a threat to land. NHC will generally provide these updates around 10:30 AM 4:30 PM CDT.

Outreach

NHC provides outreach and education throughout the year on Facebook at https://www.facebook.com/NWSNHC.

Hurricane Season Starts June 1

It’s getting to be that time of year again. Early predictions from Colorado State University indicate this should be an average hurricane season based on sea surface temperatures, the El Niño cycle, and accumulated cyclone energy.

But don’t take anything for granted. The I-storm this year will be named Imelda. Remember that one! Names recycle every six years. So prepare for a rerun.

ABC13 Exposes Progress of Kingwood Drainage Projects

3/11/25 at 5 PM and updated at 7 PM – This afternoon at 6 PM, ABC13’s Nick Natario aired a segment on the progress of Kingwood drainage projects since the passage of the 2018 flood bond.

The publication of a new interactive map by the Harris County Flood Control District (HCFCD) sparked renewed interest in flood issues – for all the wrong reasons.

Natario (left) interviewing Rehak (right) next to Taylor Gully this afternoon.

Map Misleads

The map showed the status of all flood-mitigation projects in the county. It also showed a lot of misleading information. Specifically, it called projects complete that were not.

  • The map marked the Woodridge Village and Taylor Gully Improvement Projects in Kingwood as “complete.”
  • It marked the project to add more floodgates to the Lake Houston Dam as “complete.”
  • Ditto for the TC Jester Detention Basin upstream on Cypress Creek – “complete.”
  • The Kingwood Diversion Ditch that hasn’t seen an excavator? They marked that “in progress.”

All of those assertions are false and misleading.

HCFCD may have completed parts of the projects, such as preliminary engineering reviews. But their map suggested entire projects were complete. However, in reality, absolutely no construction projects were completed to reduce flood risk on any of these projects.

In fairness, though, HCFCD did complete some maintenance projects after Harvey. And they did buy the Woodridge Village property from Perry Homes. But they have not completed any improvements to it.

Natario’s segment first aired at 4 this afternoon before I could get this post up. By the time it aired the second time at 6, HCFCD has agreed to remove the misleading information from their new map.

Suggestion for HCFCD

I talked with the flood control district this morning. They are using old databases that were not designed to do what they want to do. And so, they say, they are having translation issues with the data.

That’s fair. But please, HCFCD, work out the kinks before publishing the data. After you have proofed it, publish it then.

Don’t call a project complete because you completed a preliminary engineering study when you haven’t implemented any of the study’s recommendations.

That’s very misleading. Provide more detail and context.

People could buy homes based on your misleading information that later flood. Or the community could be denied a flood-mitigation grant because a bureaucrat a thousand miles away in Washington thinks the project is already complete.

I have invited HCFCD to publish a guest post on this issue to present their point of view. But they have not provided it yet.

If you are concerned about flood mitigation in the Lake Houston area, here is a link to the ABC13 segment by Natario that aired at 4 PM before I could get this post up.

Between the 4 and 6 PM airings, HCFCD removed the projects inappropriately labeled as “completed” from its map. The revised map now only shows work in progress.

HCFCD revised interactive map. All projects previously reported as “complete have been removed.

Thank you, ABC13! And thank you HCFCD.

HCFCD Calls Projects Complete that Have Not Even Started

3/10/25 – In the last week, Harris County Flood Control District (HCFCD) launched a new interactive map at the bottom of its homepage. In it, HCFCD calls many projects complete that have not even started.

The map supposedly contains the status of each project in the county along with links to more project details.

However, the information is riddled with errors. The map also contains several usability issues that place barriers between people and information.

Together, the issues show a disturbing lack of attention to detail and quality control that undermines the credibility of HCFCD.

Examples of Incorrectly Coded Projects

For instance, you may be pleased to know that the project to add more floodgates to the Lake Houston Dam is “complete.” It’s not. Ask Houston City Council Member Fred Flickinger who just provided an update on the ongoing engineering of the gates.

This and all other screen captures below taken on 3/10/25. Note project status in lower right corner.

Neither are the projects complete to add stormwater-detention capacity to Woodridge Village and to improve Taylor Gully. However, the map shows them completed also.

HCFCD also marked the Kingwood Diversion Ditch Project “in progress.” It’s not.

“None of this information is true!”

– Bob Rehak

With the exception of the Woodridge project, the District has not turned one shovel of dirt on any of the projects above.

The District tabled the Woodridge project in November 2023 when it decided to seek HUD funding to complete it. Here’s how HCFCD left the site.

“Completed” Woodridge Village Detention Basin. Photo taken today, 3/10/25.

HCFCD even marked the TC Jester Detention Basins on Cypress Creek complete.

However, that project won’t even go out for bid until the fourth quarter of this year.

From HCFCD’s 12-month Bid Calendar. Arrow added.

HCFCD did not respond to questions about the errors, nor did it take the error-ridden, interactive map down as of close of business today.

Usability Flaws, Too

In addition to the project-status errors, the map also contains some serious usability flaws.

For instance, clicking on the link for more information about a project sometimes takes one to a page that asks you to sign into “ArcGIS Online.”

But that requires HCFCD employee credentials.

However, take heart. If you wait several minutes, information may eventually load OFFSCREEN and ABOVE the sign-in prompt…where few would ever bother to look for it. Very clever!

A source familiar with Harris County Universal Services, the county’s IT department, attributed the bizarre performance of the map, in part, to incompetent coders and project managers with forged credentials working on H1-B visas.

That may be an even bigger problem! If you think Elon Musk rummaging through IRS data is an issue, imagine foreign nationals rummaging through your Harris County tax information. But I digress.

Why An Untested Map?

The sudden appearance of the map follows fast on the heels of the Harris County Commissioners Court meeting on February 27, 2025.

In the meeting, Commissioners adopted several measures to limit the financial impact to the county in case DOGE rescinds $1.1 billion of previously promised HUD disaster-relief and flood-mitigation funding.

In the same meeting, Commissioners also demanded an update from HCFCD Executive Director Tina Petersen about the status of every project. The reason: so they could make sure so-called “equity projects” were completed in low-to-moderate income areas before those in more affluent areas.

Precinct 1 Commissioner Rodney Ellis said he didn’t want to wait “until all the money was gone.” He added, “I know there’s not enough money to do all the projects we talked about and everybody else knows it.”

I hope Ms. Petersen provides better information to her bosses than to the public. She just received a $90,000 raise. You could hire several proofreaders for that!

No telling how many errors are embedded in the interactive HCFCD map; I am not familiar with every project in the county. If you know of other errors in projects near you, please send me a note through the contact form on this website.

Transplantation of More Northpark Trees

3/9/25 – Last week, contractors began transplantation of more Northpark trees. Residents said they wanted to save the trees. And early on, the Lake Houston Redevelopment Authority committed to saving as many as possible, especially those with ornamental value. They budgeted $700,000 for the effort.

From Loop 494/Northpark to South Entry Pond

The trees transplanted last week moved from in front of the dry cleaners on the SW corner of Northpark and Loop 494 to areas around the south entry pond on Northpark at US 59.

I wasn’t able to photograph the transplantation since it happened at night. But comparing previous and current photos shows where they moved from and to.

January 2025 photo. Trees circled in red moved.
Photo taken today. That same area photographed from a different angle this afternoon shows trees are gone.

Contractors moved trees to the south entry pond. The most beautiful occupies a place of prominence in center of this trio. Contractors transplanted the other two trees earlier.
They scattered other transplanted trees around what will become the south entry pond.

Most people will notice the trees missing from in front of the dry cleaners. But they won’t realize where they went to.

Keep Finished Design in Mind

Construction never feels pretty.

However, rest assured that the directors of the Lake Houston Redevelopment Authority/TIRZ 10 heard residents and are acting to save the trees. It’s just hard to see with all the visual noise of construction.

When complete, the entry ponds at Northpark should look as good as those at Kingwood Drive. And that is another thing residents have requested for years.

Flickinger Issues Updates on Multiple Lake Houston Dam Issues

3/8/25 – Houston District E City Council Member Fred Flickinger’s March newsletter contained updates on several Lake Houston Dam projects.

Floodgate Update

Adding more and bigger floodgates to the Lake Houston Dam will let the City lower lake levels faster in advance of major storms to reduce flood risk.

According to Flickinger, Phase II of the Lake Houston Dam Spillway Improvement Project is well underway. This phase focuses adding eleven new tainter gates. Together, they will increase discharge capacity by 79,000 cubic feet per second (cfs). And that matches the peak release rate of Lake Conroe during Harvey.

Looking west across Lake Houston Dam. The current plan to add more floodgates focuses on the earthen embankment in the foreground.

Engineering firm Black & Veatch has completed the 30% design plans. Also field activities, such as ground surveys, bathymetric surveys and geotechnical soil borings are underway. Environmental investigations including wetlands assessments, endangered species studies, and archaeological site evaluations begin next week.

In parallel, engineers are working with regulatory agencies. They include the Texas Commission on Environmental Quality (TCEQ), United States Army Corps of Engineers, and Texas Parks and Wildlife Department (TPWD). Together, they hope to streamline permitting.

The Coastal Water Authority (CWA) also met with TCEQ in December. CWA continues to work closely with the Corps and TPWD to speed approvals.

Future Lake Houston Dam Replacement Study

Recognizing the long-term needs of the region, planning is also underway for a larger project to replace the existing 75-year-old Lake Houston Dam. CWA has engaged Black & Veatch to initiate a high-level Lake Houston Dam Replacement Study in 2025.

Lake Houston Dam Repair Project – Immediate

In addition to expansion and long-term replacement planning, immediate repairs are being implemented through the $10 million Pre-Disaster Mitigation Grant Project, made possible with the support of Congressman Dan Crenshaw. This project includes:

  • Grouting voids below and around the dam structure
  • Repairing spalled concrete on spillway buttress walls

“Spalled concrete” refers to a condition where concrete begins to crack, chip, or flake away from its surface. This can expose the aggregate or reinforcing steel underneath.

Essentially, it’s a form of concrete deterioration where pieces of the surface break off, leaving pitted areas. Spalling can weaken the structural integrity of concrete and lead to further damage if left unaddressed. 

CWA is finalizing the scope and fee for additional field investigations and engineering design work. These efforts will define the exact repair locations and methodologies for construction. The engineering should take six to eight months. And construction should last another six to nine months after that.

Lake Levels Lowered for Fieldwork

Houston Public Works has lowered Lake Houston to approximately 41.0 feet. Lake Houston has a normal pool elevation of 42.4 feet.

The lower level will keep water from going over the spillway, so that another CWA engineering firm, Freese & Nichols, can perform surveys of the concrete hearth structure on the downstream side of the spillway.

Lake Level has been lowered so engineers can survey the concrete on the downstream side of the 3,100 foot spillway in the foreground.

After completion of the surveys during the week of March 14th, the levels in Lake Houston will naturally return to 42.4 feet, through rain events.

Flickinger says the District E office remains actively involved in this project. His team participates in bi-weekly coordination meetings to ensure progress continues efficiently and transparently.

Property owners along the lake should secure all belongings located at the shoreline, boat docks, and piers. Be prepared for changing lake levels, as advance notice may not be possible.

Northpark Reopened After 3 Day UPRR Closure

3/7/25 at 6 PM – Northpark reopened this afternoon after a three-day closure to let the Union Pacific Railroad (UPRR) insert a single 200-foot section of track weighing 55,000 pounds into their track across the major traffic artery.

The closure tangled traffic throughout Kingwood as tens of thousands of commuters and shoppers struggled to find alternative ways to get to their destinations.

What a welcome relief it is to have Northpark open again. I just made the roundtrip to Northpark and 494 in 20 minutes. However, yesterday, it took two hours…in the middle of the afternoon.

I took this picture at 5:30 PM. And it says it all.

Northpark has re-opened after being closed since March 5, 2025.

As I drove west to capture this shot, I saw traffic streaming by me heading east. And I knew that Northpark reopened.

What a beautiful sight! And it will be even more beautiful when this project is complete.

The Northpark expansion project has two major goals: accommodate a growing volume of traffic and create an all-weather evacuation route for 78,000 Kingwood residents.

Please try to patronize the merchants along Northpark. The last three days have been brutal for them.

For More Information

See the Lake Houston Redevelopment Authority project web pages. For more about the closure, see these related posts on ReduceFlooding.

UPRR Almost Finished, Northpark to Reopen This Afternoon

3/7/25 Updated at 2:30 PM– The UnionPacific Railroad (UPRR) has almost finished with Northpark work that caused a three day closure of one of two major traffic arteries out of Kingwood. UPRR hopes to reopen Northpark this afternoon. They say it should be open for evening rush hour.

Reasons for Closure

UPRR installed a single 55,000 pound, 200-foot-long, welded section of track across the area where ten lanes of traffic will soon go. The single section was necessary to stabilize the track against traffic that will drive over it and utilities that will bore under it.

The bridge that will carry six lanes of traffic over the tracks and Loop 494 eliminating backups in the case of evacuation. But the bridge also will create a conflict for utilities that run wires overhead in that area.

The pictures below tell the story of what happened since my last update yesterday at noon.

By 4 PM Thursday

By 4 PM Thursday, Day 2 of the 3-day closure, UPRR crews were preparing the areas next to the tracks where asphalt will go.

Prepping areas for asphalt that will feather roadway into rail crossing.
UPRR has begun demobilizing much of its heavy equipment.
They also cleared and graded the staging area where they constructed the 200-foot section of track.

That means Loop 494 expansion through that area can now re-commence.

At 10 AM Friday

This morning, Friday 3/7/25, the Northpark railroad crossing was a beehive of activity. Crews poured asphalt over the gravel next to the track so that traffic could move smoothly over them.

Looking South at Loop 494/Railroad and Northpark Intersection on 3/7/25 at 10 AM.
UPRR Crews were prepositioning the concrete inserts that will allow traffic in the surface lanes next to the bridge to move smoothly over the tracks.
Looking N as operator preps track.

While I was there, they did not actually place any of the concrete panels. However, asphalt kept arriving.

Another load of asphalt arrived as crews spread and compacted the material to create a smooth transition with the existing concrete roadway.
Adding another layer.

Reports of Train Moving Through Intersection Yesterday

Numerous people reported a train moving through the Northpark intersection yesterday. Those reports were true. But according to the railroad, the train was moving “really, really slow.”

UPRR has not yet fully stabilized the new section of track per their standards, but they are working on that now.

Reopening and Next Steps

UPRR will reopen the roadway late this afternoon, probably about 5 PM.  Variables affecting that goal include the asphalt transition between the newly installed concrete panels and the adjacent roadway. 

That asphalt arrived late this morning. And once placed, it must cool. But the roadway should open by rush hour this afternoon, according to UPRR.

The concrete panels needed for the future feeder road crossings and the two 10’ multi-use pathways still need to be installed. UPRR is still working on that. 

At 2 PM, the UPRR crew was placing concrete panels between the tracks where turn lanes and sidewalks will cross them.
Also as of 2 PM, most of the equipment including the asphalt operation had been removed from the crossing. Note the panel placement operation continuing in lower right.

UPRR also intends to place concrete panels between the tracks north (left) of the intersection above. Note the panels stacked by the white pickup in the lower left of the photo above. It is unclear whether they intend to try to do that before the re-opening.

No new signal work will be done at this time.  The existing gate arms and signals will continue to operate when the roadway opens later today. 

Other Northpark Work

Separately, the Lake Houston Redevelopment Authority used the opportunity created by the railroad work to run drainage underneath Northpark in two areas. The Harper Brothers crews are also nearly finished with those, too. So that work should not impede the re-opening of Northpark.

Drainage work under Northpark is virtually complete.
The last loads of asphalt were being placed as I left.

UPRR Inserts New 200-Foot Section of Track Across Northpark

3/6/25 – UnionPacific Railroad (UPRR) has finished splicing a 55,000-pound, 200-foot-long, single section of track into their line across Northpark Drive in Kingwood. However, more work still needs to be done. UPRR must still:

  • Install concrete between and alongside the tracks, so traffic can move smoothly over them.
  • Get signals working again.
  • Clear the intersection of Loop 494 and Northpark.
  • Clean up the TXDoT right of way on Loop 494 that they used as a staging area.

Heavy Lifting Completed

The hardest part of the job is now complete, though.

The single-section splice will stabilize the track through an area where ten lanes of traffic will go under and over it. Several utilities must also bore under it.

On the morning of 3/5, UPRR started removing the old track and moving the new track closer to the Northpark/494 intersection.

Looking S along Loop 494. Old track on left. New on right. Shot taken 3/5/25 at 8 AM.

By 2 PM yesterday, they had repositioned the new section next to the old track.

Note how much closer the new track is to the old. Shot taken 3/5/25 at 2 PM.

They also had a mountain of gravel ready to provide a fresh base for the new track.

Gravel stockpiled for new base. Shot taken 3/5/25 at 2 PM.

Because of traffic snarls throughout Kingwood, I missed the actual installation of the new track.

Sometime between 2 PM yesterday and 8 AM today, UPRR actually, removed the old track and moved the new 55,000-pound section into place. The railroad also freshened the track base with new gravel. The shots below show how it looks as of 8 AM on 3/6/25.

Looking SE at the area just north of Northpark. Note old sections of track awaiting removal. Shot taken 3/6/25 at 8 AM.

Elsewhere on Northpark

Meanwhile, Harper Brothers, the general contractor for the Northpark expansion project, used the UPRR closure as an opportunity to trench across Northpark in two places to install new drainage. The trenching took place between the U-turn and the railroad tracks.

Traffic Snarls Throughout Kingwood

As Kingwood residents detoured around the Northpark closure, traffic snarled everywhere…despite the best efforts of UPRR and HPD to help direct traffic. It was like an avalanche trying to squeeze through a pinhole.

Getting to the location above would normally take ten minutes from my house. Today, it took more than a half hour.

The Northpark closure should last through Friday. Use this time to visit merchants in Kingwood. Work from home. Or simply read a good book. This too shall pass.

It dramatizes the need for more traffic capacity and an all-weather evacuation route out of Kingwood.

During mega-storms, such as Hurricane Harvey, when Kingwood Drive is cut off, we have insane traffic congestion on Northpark.

This project will improve that situation. It will make it easier to get to US59 across the railroad tracks and Loop 494. So, allow extra time if you must travel and pack your patience.
