Northpark Update: Building Blocks Falling into Place

11/5/25 – From ground level, a driver may not see all the progress being made on the first all-weather evacuation route from Kingwood. But from the air, it’s unmistakable. One can clearly see the pieces of the final Northpark project coming together.

In the last week, contractors have:

  • Prepped and/or paved a mile of new inbound lanes on Northpark
  • Framed out most of the first junction box that will convey stormwater from one side of the UPRR tracks to another
  • Began prepping the second junction box.
  • Extended sidewalks on the south side of Northpark between Loop 494 and 59.

Below are pictures taken on Monday, 11/3/25 that show the state of the massive project.

Prep and Paving of Inbound Lanes

Looking east from the entry ponds at US59, note the sidewalks going in on the right. Contractors are bending the path to save a giant live oak tree by the Exxon station.

Also note below that contractors have removed all the old concrete from the southernmost lanes (right of center) and have begun paving new lanes from Whataburger to US59.

Reverse angle. Looking SW at the same area.

On the other side of Loop 494, there’s even more progress. Note the new lanes stretching east from Loop 494 most of the way to Russell Palmer Road.

Looking east from over Loop 494. Note new paving (right) in front of a new subdivision which will be called the Northpark Enclave.

A little farther east, contractors have laid an asphalt base that stretches for several more blocks. Concrete will soon follow.

Note the base for new paving on the right.

Also note above the gentle outward curve of the road on both sides. This is where surface roads will split to make room for the bridge over the tracks and Loop 494.

Junction Boxes by Loop 494

Contractors are in the process of forming two cast-in-place junction boxes on either side of the UPRR tracks that parallel Loop 494.

They finished two bores under the tracks in October. Now, they are creating the junction boxes, one on either side of the tracks. Together, will help convey stormwater to the Kingwood Diversion Ditch.

All this work is taking place under ground and is invisible from the road.

Looking down at the rebar that will reinforce the walls of the western pit between Loop 494 and the tracks.
Work is just starting on the eastern junction box in front of Self-U-Storage.

Sidewalks between US59 and Loop 494

Next Steps

Ralph De Leon, the Lake Houston Redevelopment Authority project manager for the Northpark expansion project, says the next steps will be:

  • Opening up all the westbound lanes between Loop 494 and US59
  • Opening up all the eastbound lanes on both sides of Loop 494
  • Finishing the driveways on the outbound side of Northpark east from the Kingwood Diversion Ditch.

In the meantime, pack your patience. And focus on how nicely this will all work when complete.

Floodplain Maps for 5,316 Acres West of Kingwood Contradict Developer’s Claim

11/4/2025 – FEMA floodplain maps contradict a claim made by Scarborough Development/San Jacinto Preserve in a presentation made to the City of Houston and Harris County officials on 10/29/25.

The developer recently bought 5,316 acres, mostly in the floodplains and floodways of Spring and Cypress Creeks, and the San Jacinto West Fork. The land lies in both Montgomery County and the City of Houston’s extra territorial jurisdiction. The developer also wants to build a bridge into Harris County.

In documents obtained from the City of Houston, the developer claimed it would only be “developing land at or above the Atlas 14 100-year floodplain.” See copy in red box below.

Presented by developer to City of Houston and Harris County on 10/29/25.

However, superimposing their development plan on FEMA’s current floodplain maps developed before Atlas 14 contradicts that claim. Why?

The extent of proposed development matches the limits of pre-, not post-, Atlas 14 100-year floodplains.

Net: developing in this area is more dangerous than it may look. 500-year floodplains could soon become 100-year floodplains.

For more detail, see the discussion of Atlas-14’s history and the sequence of maps below.

A Brief History of Atlas 14

FEMA’s current floodplain maps for this area date to 2014, four years BEFORE the start of Atlas 14 in Texas. And to my knowledge, FEMA has not yet released new flood maps based on Atlas 14 for this region.

From FEMA floodplain map of Scarborough/SJP property. Effective date: 8/18/2014. Screen captured today.

NOAA began updating rainfall precipitation frequency estimates in 2004; they called the effort “Atlas 14.” But NOAA didn’t update Texas statistics until 2018. Such rainfall estimates form the basis for flood maps.

In Montgomery County (MoCo), pre/post estimates for the standard 100-year/24-hour rainfall varied by more than a third. MoCo adopted Atlas 14 values of ~16.1 inches for the 24-hr, 1% storm (at Conroe), up from the previous standard of ~12 inches. That’s an increase of 4.1 inches or 34%.

Just as important, until earlier this year, MoCo drainage regulations often let developers avoid building stormwater detention basins that would offset that additional rainfall.

Also consider that Montgomery County has been one of the fastest growing counties in the region and in America. Its population has grown by almost a third (31%) since 2018. That population growth comes with a growth of impervious cover (roofs, driveways, streets, parking lots, etc.) that doesn’t soak up rainfall.

I’m not aware of any recent studies that show the cumulative impact of additional rainfall and impervious cover together with a deficit of detention.

Given those issues, common sense says flood elevations would increase. And in fact, preliminary guidance from Harris County indicates that floodplains will expand by 50% to 100% when FEMA releases updated flood maps based on Atlas 14.

New Plans Show Development Extending to Old 100-Year Floodplain

When I first saw the developer’s new plans, the plans didn’t seem to match the claim that they would only develop land “at or above the Atlas 14 100-year floodplain.” That made me suspicious. So, I performed an experiment.

I superimposed the developer’s plans over FEMA’s current (pre-Atlas 14) map dated 2014. I then varied the opacity of the layers in Adobe Photoshop so I could see how the two matched up. Long story short, they matched perfectly. See the sequence of images below.

Layer 1: From FEMA’s Flood Hazard Layer Viewer. Scarborough property is in center between Spring Creek (diagonal) and West Fork (right). Brown areas = 500-year floodplain. Aqua = 100-year. Striped = floodway.

Next, I superimposed the development plan that Scarborough presented to City of Houston and Harris County.

Layer 2: Gray areas with waffle pattern represent claimed “net developable area.” Red = property boundary.

Then, I varied the opacity of the development plan until you could see the floodplains behind it.

Composite with partial transparency of overlay

Enlargement clearly shows that development stops at the old, pre-Atlas-14, 100-year floodplain.

White lines from 2014 FEMA map form boundary between 100- and 500-year floodplains. And waffle patterns from developer’s plans stop at white lines.

New maps reflecting higher rainfall rates and more impervious cover will likely show those white lines cutting well into the brown so-called developable areas, if not eliminating some altogether.

Where Did Developer’s Claim Come From?

So, where did the developer’s Atlas 14 claim come from? I have talked to three people who were in the meeting. Not one could tell me with certainty. They all expressed reservations and doubts about it.

I have also reached out to Scarborough several times to understand their position, but they have yet to return phone calls or emails.

So, I’m going to remain skeptical until I see proof of their claim and FEMA’s new Atlas 14 maps. FEMA may release them in 2026. But the proposed maps will then go through public comment and revision cycles. That could mean they won’t become official for at least another three years.

Make This An Election Issue

In my opinion, the best use for this property would be to turn it into a state park. That would help protect areas both up and downstream. With an election coming up next year, our representatives will have their ears to the ground. The time to start a letter-writing campaign is now. Contact all candidates.

Turn this into an election issue.

Make sure we elect someone who is more interested in protecting public safety than private profits.

How Could Hurricane Melissa Get So Strong So Late in the Season?

11/2/25 – Hurricane Melissa disappeared off the tracking charts yesterday. And when it did, one of the most powerful storms in recorded history went into the history books.

Many things made Melissa unusual and stunned meteorologists. They included the storm’s deep pressure, high winds, rapid intensification, death toll, destruction, and its timing within the hurricane season.

And all of that happened in a season that has, so far, spared the U.S. mainland from any landfalling hurricanes.

A Normal Season

Usually, the Atlantic Hurricane season is largely over by the end of October.

But this season was different.

This Season

Melissa was the 13th named storm of the season.

One tropical storm, but no hurricanes have hit the US mainland so far this year.

In May this year, NOAA predicted an above average season with 13-19 named storms, of which 6-10 would become hurricanes, including 3-5 major hurricanes.

So far, we’ve had 13 named storms. Five became hurricanes, four of which reached major hurricane strength. See below.

Why So Strong, So Late?

First, we had very warm waters in the Caribbean – 1.9ºC to 2.8ºC above average for the region and season. That’s up to 5º F warmer than average.

More importantly: the warm layer extended to depth — meaning the storm could churn up deeper water without encountering cooler up-welled water that normally weakens storms.

Second, reduced wind sheer and steering currents caused it to meander slowly. This helped it sit over very warm waters while enhancing its strength. 

Melissa underwent two rounds of rapid intensification, including a gain of ~70 mph in 24 hours — an “extreme rapid intensification” event. Because water was abnormally warm for that late in the season, and other inhibiting factors were low, the conditions aligned for a major hurricane even though the calendar was later.

Sea surface temperatures ordinarily decline and atmospheric conditions become less favorable this late in the season. But not this year. So, Melissa could reach peak strength even in late October. Some scientists hypothesize that climate change may have played a role. Others believe it was just the random confluence of favorable factors.

Warm water is necessary but not sufficient to create a major hurricane. In this case, the atmosphere cooperated, which is part of why Melissa could intensify so late and so rapidly.

Typically by late October, conditions become less favorable for hurricane formation (cooler oceans, increasing shear, etc.). 

One For the Record Books

One study estimated that the extra warming of the ocean helped boost Melissa’s maximum wind speed by about 10 mph and increased its damage potential by ~50%.

ABC News reported that at least two hurricane-hunter aircraft had to turn back from Hurricane Melissa due to extreme turbulence: one from the U.S. Air Force Reserve 53rd Weather Reconnaissance Squadron and another from NOAA.

Melissa made landfall in Jamaica with sustained winds of 185 mph, tying it for the strongest Atlantic hurricane landfall by wind speed. (Wikipedia+4AP News+4CBS News+4).

A scientist from the University of Miami onboard the Hurricane Hunter recorded a spot wind gust of 252 MPH. If verified, it will be the highest speed ever recorded in a tropical cyclone by a dropsonde. That rivals winds in EF5 tornadoes!

Melissa also recorded a central pressure of 892 mb, tying the record for third‐lowest minimum central pressure in the Atlantic basin. (CT Insider+1).

So far, Melissa is the strongest tropical cyclone of any kind worldwide in 2025.

USA Today reported today that the storm left more than 60 people dead in Haiti, Jamaica and the Dominican Republic.
