There's a quiet war being fought across southern Denton County right now. The weapons aren't guns or courtrooms — they're site plans, parking variances, and land acquisitions. The combatants are some of the biggest names in grocery retail in America. And the prize is the loyalty of tens of thousands of families flooding into one of the fastest-growing corridors in Texas.
Tom Thumb just fired the opening shot. But H-E-B and Costco are loading up.
Here's everything you need to know about the grocery store wars — and why it matters far beyond where you shop on Saturday morning.
The Battleground: Why Southern Denton County?
To understand why major grocers are converging on this corridor, you have to understand the scale of residential growth happening here.
On the Argyle and Northlake side of I-35W alone:
- Harvest by Hillwood — 4,000+ homes at full build-out (~11,000–12,000 residents)
- Pecan Square by Hillwood — 3,100 homes, projected 9,000–10,000 residents at full build-out
- Landmark by Hillwood — 6,000 homes and 3,000 multifamily units in Denton, projected 20,000 residents at full build-out
- Harvest House — 349 luxury apartments and townhomes now leasing adjacent to Harvest Town Center
- Treeline by Hillwood — 2,700 homes at full build-out (~7,500–8,000 residents) in Justin
On the Flower Mound side:
- Furst Ranch — 2,300 acres, 3,000 single-family homes and 6,000 multifamily units at full build-out, projected 20,000+ residents
Add it all up and you're looking at 50,000 to 60,000 new residents flooding into this single corridor over the next two to three decades — before you factor in AllianceTexas's 66,000+ direct jobs drawing workers from across the region. That is the trade area these grocers are betting on.
These aren't speculative projections. The rooftops are here, more are coming, and grocery retailers have taken notice. "There's definitely a demand," said Christy Lara, Director of Communications and Public Relations for Albertsons, when Tom Thumb broke ground in Argyle. "We've heard from so many residents in this area: 'We really need a grocery store.'"
That demand is now being answered — from multiple directions at once.
The Players
Tom Thumb — Opens Friday March 6, 2026
Tom Thumb made the first move and won the race to the Harvest and Pecan Square trade area. Their 63,000-square-foot store at 1046 Market Way in Argyle opened March 6, 2026 — a full-service flagship with an in-store Starbucks, drive-thru pharmacy, DriveUp & Go curbside pickup, full bakery, deli, meat and seafood counter, produce, and floral.
The $12.6 million investment — built by Ridgemont Construction with financing from Frost Bank — planted a flag at the northwest corner of I-35W and FM 407. For Harvest and Pecan Square residents, years of driving 20+ minutes to Denton, Flower Mound, or Trophy Club for groceries are over.
Tom Thumb's parent company Albertsons didn't make this bet casually. Major grocers conduct extensive demographic and traffic analysis before committing to a $12 million-plus build. Their presence at Harvest Town Center is effectively a vote of confidence in the long-term trajectory of this corridor.
H-E-B — Coming to Denton (Twice) and Flower Mound
H-E-B is playing a longer game — and playing it on three fronts simultaneously.
Denton, Store 1 — Robson Ranch Road (Landmark by Hillwood): Denton's first H-E-B is currently under construction at the northwest corner of I-35W and Robson Ranch Road, inside Hillwood's massive Landmark development. Construction broke ground in fall 2025 and the store is scheduled to open in spring 2027. This location was originally a contested site — there was a real possibility it could have landed on the Argyle side of I-35W. Argyle lost that round. Denton won. (Tom Thumb arrived in Argyle first anyway.)
Denton, Store 2 — University & Bonnie Brae: H-E-B is also building a second Denton store at the northeast corner of University Drive and N. Bonnie Brae Street, near the University of North Texas campus. This 119,000-square-foot store is set to begin construction in spring 2026 with an opening expected in fall 2027. H-E-B purchased this property back in 2015 and held it for nearly a decade before moving forward.
Flower Mound — Furst Ranch: H-E-B purchased 22.8 acres at the northeast corner of Highway 377 and FM 1171 within the Furst Ranch development in July 2025. Flower Mound Town Council unanimously approved the grocer's parking ratio for a 110,000-square-foot store with 733 parking spaces. No construction timeline has been announced, but H-E-B has confirmed they are actively moving forward. "We have been having great communication with them and it is moving forward," said Becca Wang, H-E-B's predevelopment services manager, at the May 2025 council meeting.
H-E-B's Furst Ranch location sits on the western edge of the corridor — serving a different trade area than Tom Thumb's Harvest Town Center location. These aren't competing head-to-head. They're dividing the territory.
Costco — Proposed for Flower Mound (Unconfirmed)
The newest and most intriguing development is a proposed Costco Wholesale at the Cottonwood Retail Development in Flower Mound — an 86.6-acre site east of FM 2499, stretching from Dixon Lane to FM 407, adjacent to the Marcus High School athletic complex. As of February 2026, the project listing in Flower Mound's development tracker added "(COSTCO)" to the project description. No formal announcement has been made by Costco or the developer, and this remains unconfirmed. Treat it as a strong signal, not a done deal.
If confirmed, this would be a different kind of grocery play than Tom Thumb or H-E-B. Costco warehouses aren't full-service grocery stores in the traditional sense — they're bulk wholesale destinations with pharmacy, optical, gas, and food court amenities. But they draw significant traffic and signal serious long-term retail commitment to a trade area.
What This Means for Home Values
Here's where it gets interesting for homeowners and buyers. The arrival of major grocery retailers isn't just a convenience story — it's a home value story.
Multiple data sources confirm that proximity to quality grocery stores has a measurable positive impact on home values and appreciation rates:
- Research from ATTOM Data Solutions found that homes near major grocery brands appreciated significantly faster than the national average over five-year periods — in many cases between 33% and 58% depending on the chain.
- A study cited in "Zillow Talk" found that homes within a mile of a Starbucks (like the one inside the Argyle Tom Thumb) appreciated roughly 30% faster than homes farther away.
- Research from real estate consulting firm RCLCO found that multifamily buildings with a grocery store component brought in 5.8% more in initial rent than comparable properties without one — which is directly relevant to Harvest House, sitting steps from Tom Thumb.
- The National Bureau of Economic Research concluded that grocery store openings encourage surrounding property prices to rise, reinforcing the long-held real estate principle that amenity access drives demand.
The mechanism is straightforward. When a major grocer commits to a location, it signals to the broader retail market that the trade area is viable. Other retailers follow. Restaurants follow. Services follow. The area becomes more complete — and more complete areas command higher prices.
The Tom Thumb opening at Harvest Town Center, with Chuy's already under construction and 16+ additional retail spaces still available, is exactly this cycle playing out in real time.
The Argyle Angle: What Argyle Didn't Get (and Why It Doesn't Matter)
Argyle made a well-publicized run at attracting H-E-B to their side of I-35W. The city was actively courting the San Antonio-based grocer for a site along Robson Ranch Road. H-E-B ultimately chose Denton.
At the time, some read this as a loss for Argyle. In hindsight, it may have been a push. Tom Thumb arrived instead — and arrived first. Argyle's residents got their full-service grocer at Harvest Town Center before any neighboring corridor did. And the H-E-B that went to Denton and the one proposed for Furst Ranch in Flower Mound will serve the broader region without directly threatening Tom Thumb's trade area at I-35W and FM 407.
The net result: southern Denton County is becoming one of the most grocery-rich suburban corridors in North Texas. Residents of Harvest, Pecan Square, Treeline, and the broader Alliance corridor will soon have access to multiple major grocers within a reasonable drive — a marker of a truly mature suburban market.
What This Means If You're Buying or Selling
If you're buying in Harvest, Pecan Square, or Treeline: The grocery infrastructure is here. Tom Thumb is open. Chuy's is under construction. More retail is coming to Harvest Town Center. The "I have to drive 20 minutes for groceries" objection that may have given you pause a year ago? It's gone. This is exactly the moment to buy — when the amenities have arrived but prices haven't yet fully reflected the corridor's maturity.
If you're buying in Flower Mound near Furst Ranch: You're buying ahead of a $29 million infrastructure investment, a potential H-E-B, 1,400+ homes, and 500,000 square feet of retail. The playbook is identical to what Harvest and Pecan Square residents experienced five years ago — and look at those communities now.
If you're selling in this corridor: The story you can tell a buyer is getting stronger every month. Tom Thumb open. Chuy's coming. Harvest House leasing. Phase 2 of Harvest Town Center still filling out. H-E-B and Costco nearby. Use it.
The Bottom Line
Grocery retailers don't make $12 to $30 million land commitments based on hope. They commit based on data — traffic counts, household incomes, rooftop projections, and demographic profiles. When Tom Thumb, H-E-B, and a potential Costco all converge on the same 15-mile stretch of southern Denton County within a 24-month window, that's the market speaking.
What it's saying is: this corridor is real, it's growing, and it's not slowing down.
We've been saying that to our clients for years. It's nice when the grocery stores agree.
