The map of Flower Mound could change slightly if the town council approves a boundary adjustment and 70-acre land swap with Argyle at Monday’s meeting.

The redrawn lines are proposed to accommodate Monarch, a 187-acre mixed-use development near Denton Creek Boulevard and Interstate 35 West. The developer, Schmitz Realty Group of Denton, has also asked for a few new modifications and exceptions to its planned development that was approved by town council in January 2025.

These changes come soon after TXDOT released its annual Unified Transportation Program, which details projects that are likely to be funded in the next two years. Frontage roads for I-35W and an overpass at Denton Creek Boulevard were on the new list.

“That's obviously been a huge catalyst for this development. Specifically, for the retail portion of this development,” said Jonathan Kerby with the engineering firm Kimley Horn.

Schmitz Realty Group is asking the town to amend its planned development to increase the number of big box retailers from four to five. In order to make room for those retailers on the property, Kerby said, they had to figure out a space to collect stormwater runoff.

With the land swap, the Town of Flower Mound would receive 8.6 acres from Argyle to build a dry detention pond where there is a natural low point on the property. It would support the Monarch development and increase the amount of retail space the developer could put in along I-35W, according to the staff report.

The Town of Argyle would get 62.2 acres, of which 59.3 would be deed-restricted to only be used for development of park and open space. The public does not currently have access to this piece of land because of “floodplain constraints near Denton Tap Boulevard,” the staff report said. There is public access from the Argyle side through Avalon at Argyle, a mixed-use development.

That tract of land would be dedicated by Centurion American to the Town of Argyle for a park to be used by residents of Monarch, Canyon Falls, and Avalon at Argyle, according to a letter of intent.

The other 2.9 acres given to Argyle could be developed without restrictions.

In all, the amount of land switching between municipalities would total 70.5 acres.

The change is not considered annexation, Lexin Murphy, director of development services said. That occurs when a piece of land that is not currently part of any municipality and within the town’s extra-territorial jurisdiction, is brought into one. Flower Mound does not have any of those ETJs left, so future annexation is unlikely.

If the Flower Mound Town Council approves the land swap and boundary adjustments, Argyle Town Council still needs to vote on it as well. That council is expected to consider the items at its Sept. 21 meeting.

The developer of Monarch will also be asking on Monday night to increase the number of allowed gas stations from two to three. Two would be attached to big box retailers and the third, which would require special use permit, would be standalone.

The changes, if approved, would include decreasing the amount of townhomes from 290 to 250. Those will be priced between $550,000 and $800,000, depending on the design.

“It seems like a lot of this proposal is better in some ways, particularly what caught my eye was the max density being decreased,” said chairman Gregory Schultz. “I think a lot people will appreciate that.”

Still, the number of gas stations concerned a few commissioners. Commissioner Scott Langley pointed out that gas stations do not contribute much to sales tax revenue.

In addition, there is a request to allow outdoor displays, sales and storage for two Home Improvement Centers in Monarch. In June, the town council approved those types of displays for Lowe’s at the corner of Long Prairie Road and Justin Road after the store was found to not be in compliance with town ordinances. The Home Depot on the south side of town near Lakeside Parkway currently has an application in with the town to allow those uses as well.

“We were watching with bated breath earlier this summer to see what would happen,” Kerby said.

An earlier version of this story misstated the developer’s name. It is Schmitz Realty Group.
