Back in January of this year, I posted about two new developments on Gully Branch south of Splendora Junior High School on FM2090. At the time, two companies (Townsend Reserve, Ltd. and Forestar USA had begun to clear approximately 600 acres. Six months later, the trees are gone and the companies are installing infrastructure, such as roads and drainage. This area eventually drains into the the East Fork San Jacinto and Lake Houston.
Ultimately, the cleared area shown in the pictures below will almost double. The two companies combined own 1209 acres.

The first three shots below form a series as I panned right from east to west while looking south.

The next two shots look west from farther west. The first shows Gully Branch (center) as it moves from Townsend property (top of frame) to Forestar property (bottom).

If you look closely at the photo above, you can see excavators and dump trucks already working on additional detention ponds near the top of the frame. See map below.
WGA developed the drainage impact analyses for both developments using 2014 flood maps (see Townsend’s below). In fairness, WGA did attempt to calculate new flood elevations using its own measurements. But illustrations showing the old floodplain outlines, without mention of coming map changes, may mislead potential buyers.

Elevation Land Solutions developed the construction plans for Townsend. It disclosed flood risk more fully.
Disclaimer for Townsend Reserve in Elevation Land Solutions Plans found on virtually every page.
In fairness to developers, they can’t put their plans on hold indefinitely while new flood maps are drawn and approved. However, in fairness to buyers, you would think the engineering documents would at least disclose the potential of new maps based on Atlas-14 data. I’ve read fuller disclosures on an aspirin bottle.

The Signorelli Company (TSC) of The Woodlands, which developed Valley Ranch, has purchased another 3,000 acres of land near Splendora. The tract will become a master-planned community with more than 7,000 single-family homes in East Montgomery County. Located north of FM 2090 and west of Daw Collins Rd., the new development will be 15 minutes from Valley Ranch and five minutes west of Interstate 69.
Senior VP Mike Miller said, “We planned the community to provide a unique lifestyle for residents – outside with nature. We are confident the amenities will attract a variety of homebuyers.”
Amenities will include hundreds of acres of open space, numerous parks, miles of meandering trails, and various recreation areas.
TSC will break ground this fall, with the first phase of single-family homesites delivered by the end of 2023. Upon completion, the community will also have one million square feet of multi-family, office, medical, retail and hospitality space.
Maps of Area
According to Signorelli, new homes will range from the $250s to $700s. Signorelli did not announce a name for the development. Planning is still underway.

Google Earth (above) shows that dense forests cover most of the area, with a few small, scattered farms and ranches. I drove there today to get a closer look. My initial impressions were correct. Gorgeous, secluded country homes on large acreage dot the areas surrounding Signorelli’s land. See below.

Virtually all of this forest is in some kind of floodplain. See FEMA map below.
Much of Land in Floodplains
FEMA’s National Flood Hazard Layer View shows that large parts of the Signorelli site are in the floodway (striped), 100-year floodplain (aqua) or 500-year floodplain (brown).Photo above this map was taken looking north from red dotted circle.
Keep in mind that the flood map above is based on 2014, pre-Atlas 14 data. The floodplains will expand even further when FEMA updates the flood map.
Current Residents Worry About Development’s Impact on Flooding
I talked to one lady today who lived near the clearing (shown in the first drone photo above) for 55 years. She said she never flooded in all that time. But she worries that she will now. She understood intuitively how the acceleration of runoff from developments, if not properly mitigated, can result in higher flood peaks. She also worried that changes to the slope of the land around her might funnel water toward her property, just as Valley Ranch did to some surrounding homes and businesses.
Only time will tell if her fears are founded. Based on the FEMA flood map above, it appears that Signorelli will need to move a significant amount of earth to elevate homes above floodplains. Signorelli will also likely need to create many detention ponds for an area this large.
Say Goodbye to the Era of Country Retreats
One thing is certain, however. The era of country retreats in this area is history.

The Texas Water Development Board (TWDB) has compiled an amazing list of resources for those concerned about flooding. Among them: a new Community Official Flood-Resource Guide.
New Community Official Flood-Resource Guide
The Flood-Resource Guide contains information to aid community officials such as floodplain managers, city officials, emergency personnel, and others. While TWDB is targeting community leaders with this particular information, it can benefit anyone concerned about flooding. This guide also makes a great resource for teachers. So why wait for third-parties to convey information to you?
The information includes best-practice guides, links to beneficial websites, videos, and toolkits.
Among the eye-openers for me were results of a statewide survey conducted by TWDB in 2020. One of the questions was, “What are your primary concerns related to flooding?” Amazingly, financial damages fell near the bottom the list. Insufficient infrastructure, preparedness, and poor policy and management topped the list…even above human life!
From page 62 of the 68-page Community Official Flood Resource Guide: Volume One.Based on 300 respondents.
This 68-page Community Official Flood-Resource Guide is packed with useful information that will help you reduce flood risk and talk about it with your relatives, neighbors and friends.
Other Useful Links
The TWDB page where you can download the new Flood-Resource Guide also provides dozens of other links with information that directly targets residents as well as flood professionals.

One thing is certain, however. The era of country retreats in this area is history.
The Houston Business Journal published an article on the Signorelli development last week. It listed seven new master-planned developments going in nearby. But the list didn’t even include the closest two, Townsend Reserve and Splendora Crossing on FM2090, about a mile to the southeast and immediately south of Splendora High School. Those have already consumed at least another thousand acres of forest. More on those tomorrow.
