New Kingwood-Sized Development Upstream from Kingwood

4/4/25 – A Kingwood-sized development just upstream from the I-69 Bridge over the San Jacinto West Fork is half built out and growing quickly thanks to the construction of Townsen Blvd. which began recently in Montgomery County.

The area is bounded by the Grand Parkway, Spring Creek, and the San Jacinto West Fork. It lies almost entirely within floodways and floodplains. And it’s pockmarked by wetlands. A respected hydrologist told me that further development in that area would be “like aiming a fire hose at Kingwood and Humble.”

Townsen construction will open up many thousands of acres to new development. That has the potential to increase flood risk if newly developing areas receive insufficient mitigation. And that has many people asking questions.

Location and Size

Let’s begin by looking at maps that put the area and plans for it in perspective.

Construction of a major new thoroughfare in the area on the left will open up thousands of remaining acres to development. It’s called Townsen Blvd and will be four divided lanes.

Construction on the first segment began recently. And Montgomery County voters will decide whether to fund the next segment in a bond election on Saturday, May 3, 2025.

The green section is a major link in bigger plans that could eventually take the road across Spring Creek to hook up with Townsen Boulevard in Humble. Right now, plans show that section terminating at Rayford Road. But what about plans beyond that? The map below from MoCo’s 2021 transportation plan shows Townsen eventually pushing through to Spring Creek.

In 2022, I wrote about a related proposal to build a bridge across Spring Creek that would connect to Townsen Blvd. in Humble on the Harris County side of the creek.

Construction Already Starting at North End

Recently, work on the first portion of MoCo’s Townsen Boulevard started near SH99 (Grand Parkway). Photos below show contractors have only finished small segments of the first section so far. But new subdivisions and schools are already springing up adjacent to those sections and creating a stir that has area residents buzzing. See representative photos below.

Wetlands and Floodplains in Abundance

FEMA’s National Flood Hazard Layer Viewer shows that floodplains cover almost all of the area where the first two legs of Townsen Blvd. will be built. The map below is so busy that for reference, I had to superimpose a bright red line where Townsen will go.

This map will likely get worse. It is based on data acquired after Tropical Storm Allison in 2001. Experts say the floodplains and floodway will expand 50-100% when FEMA updates the map with new Atlas-14 data developed after Harvey.

But the quantity of wetlands in this area represent an even bigger problem. See the map below from the U.S. Fish and Wildlife Service National Wetlands Inventory.

Wetlands are nature’s sponges. Paving them over increases runoff and the risk of downstream flooding. The developers seem to be constructing a series of “lakes” around which they’re building homes. Such lakes are really detention basins in disguise. But because of the old flood maps, uncertainty remains. Will they offer sufficient mitigation?

Is Bridge a Real Possibility?

Neighbors want to know more about impacts of the road. That will depend on how far south Townsen Blvd. goes and whether a bridge across Spring Creek is a real possibility.

I asked several officials what the probability of such a bridge is.

Jason Stuebe, Humble City Manager, said, “Honestly, I don’t have much information to share. The developer completed the portion of the roadway within Humble, stopped at the city limits and that’s about the last we heard from them.”

Eric Heppen, Harris County Precinct 3’s head engineer, said, “We heard a few … rumors but nothing formally.  To be fair, I hear rumors about it once a year at this point. Harris County has not been contacted about it and we have at least some of the jurisdictional rights over the creek. We reminded Montgomery County recently that we cannot do a joint project with them unless they adopt current Harris County Drainage Criteria.”

More impact data to follow as I learn more details.
