Trinity Mills TOD Corridor

The 26-acre Trinity Mills Urban Village is reshaping the area where the DART Green Line, DCTA A-Train, I-35E, and the President George Bush Turnpike converge. Here's what the redevelopment means for nearby home values.

Boundaries: Centered on the Trinity Mills DART Green Line / DCTA A-Train station, bounded roughly by Trinity Mills Road, Old Denton Road, and the President George Bush Turnpike.

The single most consequential redevelopment in Carrollton right now is happening at the Trinity Mills station. A 26-acre transit-oriented development called the Trinity Mills Urban Village is taking shape at the convergence of the DART Green Line, the DCTA A-Train commuter rail, Interstate 35E, and the President George Bush Turnpike — and the homes within a one-mile radius will feel the value shift before most owners realize what’s happening.

What’s actually being built

The 2022 Master Plan, exhaustively documented on CarrolltonTXDevelopment.com, calls for a mix of Class A office space, luxury multifamily housing, a name-brand hotel, and a three-acre public esplanade connected to the Nob Hill Greenbelt. The Trinity Mills station is one of the few points in Dallas-Fort Worth where two separate rail lines meet two major highways, which makes the location structurally unusual — it’s not just a station, it’s a regional transit interchange.

The financial machinery behind it is the Tax Increment Reinvestment Zone (TIRZ), with the City of Carrollton and Dallas County participating at a 65% rate. Revised plans project roughly $19 million in TIRZ revenue over the life of the zone, captured strictly for localized infrastructure improvements. The Carrollton-Farmers Branch ISD and Dallas County Community College District elected not to participate, which is worth noting because it constrained the financing model and forced a 2012 re-evaluation by Stein Planning, LLC after the 2008 recession derailed the original timeline.

Why this matters for home values

Three forces are now working on residential prices in this corridor:

First, transit accessibility premium. Properties within a 10-15 minute walk of an active rail station consistently outperform comparable inventory at greater distances. The combination of two rail systems and two highways at a single point amplifies this effect. As the Urban Village fills in, that walkability premium grows.

Second, employment density. Class A office space at the station brings a daily population of professionals who want to live near where they work. That demand is pre-loaded into the housing market the moment the office space opens, not when it gradually fills over years.

Third, surrounding amenity uplift. The three-acre esplanade, hotel, and ground-floor retail create the kind of mixed-use density that converts a transit-adjacent neighborhood from “convenient” to “destination.” That conversion is visible in price comparables from similar TOD projects elsewhere in DFW — Las Colinas, Mockingbird Station, the Cypress Waters development.

What it doesn’t mean

A TOD project doesn’t lift every house in the radius uniformly. The properties that benefit most have specific characteristics: smaller lot sizes (because higher density users don’t want sprawling yards), proximity within ¾ of a mile, decent existing condition that doesn’t require major capital before sale, and zoning that allows for the kind of buyer demographics moving in.

Older homes on larger lots in the broader Trinity Mills area may actually underperform the city average because their buyer pool — typically empty-nesters or move-down sellers — is the wrong fit for the changing demographic mix.

Practical implications for current homeowners

If you own in this corridor, the next 18-36 months are the window where the Urban Village transitions from “announced” to “obvious.” The pricing signal typically arrives just before the visible build-out completes, because professional buyers and investors price in the future state.

Two property profiles to watch closely:

1. Three-to-five-bedroom homes built between 1985-2005 on lots under 0.25 acre within ¾ mile of the station. These will be the most competitive listings during the lift period.
2. Smaller older homes (under 1,800 sqft) on similar-sized lots within ½ mile. These may attract teardown interest from developers, particularly if zoning shifts to allow attached or stacked units.

Where this is in the public record

The 2022 Master Plan, the TIRZ Project and Finance Plans (revised by Stein Planning, LLC in 2012), and the current TIRZ Board of Directors (chaired with members James Golf, Elif Cakir, Randal Mcclanahan, and Tina Hernandez) are all documented at CarrolltonTXDevelopment.com. The DART Green Line and DCTA A-Train schedules and ridership data are public. Anyone telling you specifics that aren’t traceable to one of these sources is making them up.

The most valuable thing a Carrollton homeowner can do right now is read the actual Master Plan. It’s 80 pages, plain language, and explains what’s coming with the kind of specificity that the marketing materials don’t capture.
