About 7,000 cars a day cross High School Road near its intersection with Highway 89 right now, on the edge of the two neighborhoods most people mean when they say South of Jackson. That number is about to become obsolete. Once Teton County finishes the final half mile of Tribal Trail Road and the Gill family's long-planned development on the northern edge of South Park gets built out, the county's own traffic study projects roughly 18,000 cars a day on that same stretch. The Gill land alone is projected to add about 2,070 of them.
If you're touring homes in Rafter J or Melody Ranch this fall, that number matters more than the median price you already found. It's the clearest evidence of something buyers here tend to miss: the quiet, family-scale character of South of Jackson was never a permanent feature of the land. It was the outcome of a specific zoning deal cut in 1978, and a second one cut in the late 1990s. A third deal is now working its way through county approvals on the parcel directly north of Rafter J, and on its own, one landowner's slice of that deal could out-produce every lot Rafter J has ever held.
What built the neighborhood you're touring
Rafter J exists because three developers, Floyd King, Jerry Wilson, and Chuck Luton, subdivided a 600-acre cattle operation called the Brown Ranch in 1978 and struck a bargain with Teton County: designate 60 percent of the land as permanent open space, and in exchange, get approval as the county's first Planned Unit Development. That trade produced 360 homesites clustered along Flat Creek, an owner-run HOA established in 1979 that still protects the open space and trails, and a separate water and sewer district that has nothing to do with the town's utilities.
Melody Ranch, platted a couple of miles further south on South Park Loop Road in the late 1990s, ran the same trade in reverse. Instead of holding density down to preserve open space, the developers preserved roughly 70 percent of the land as open space in exchange for permission to build at higher density on the remainder, producing the trout pond, parks, and playgrounds that now define the neighborhood's identity.
Neither subdivision is an accident of geography. Both are the physical record of a negotiation between a landowner and the county, and that negotiation is the actual mechanism that makes these two neighborhoods the most attainable year-round, family-scale streets left within a few miles of Town Square.
| Rafter J | Melody Ranch | |
|---|---|---|
| Established | 1978 | Late 1990s |
| Original land | 600-acre Brown Ranch | South Park Loop Road parcel |
| Land-use trade | 60% open space for PUD status | 70% open space for higher density |
| Governance | Owner-run HOA (since 1979) plus separate water and sewer district | HOA manages parks, pond, and open-space plan |
| Distance from Town Square | About 3 miles, 5 minutes by car | About 5 miles, 9 minutes by car |
The market is already telling you this is scarce
That scarcity shows up in the numbers. As of a March 2026 neighborhood report, homes in Rafter J were averaging 84 days on market, noticeably faster than the broader Jackson market, and several properties had traded off market entirely, a sign of demand that never shows up in public listing data. The buyer pool skews toward move-up families and condo owners stepping into their first detached home, not the vacation or ultra-luxury buyers who dominate elsewhere in the valley. Pricing in the neighborhood has also split: thoughtfully modernized homes are commanding a real premium, while untouched 1990s-era properties sit longer and require sharper pricing to move.
None of that is surprising once you understand the supply story. Rafter J and Melody Ranch aren't just popular. They're two of the only places in the valley where the 1978 and late-1990s zoning deals happened to produce a critical mass of detached, family-scale homes within a bike ride of Town Square. Everywhere else, land economics pushed toward larger estates or higher-end product. That's why the inventory here is tight and why it moves fast when it appears.
The next version of that deal is already approved
What most listings won't tell you is that the same trade is happening again, directly adjacent to Rafter J, at a scale the valley has never seen. The parcel is called Northern South Park, roughly 200 acres owned by two families, the Gills and the Lockharts, sitting between the southern edge of Jackson's town limits and Rafter J itself. Teton County commissioners approved a Neighborhood Plan for the site in March 2024, and the framework governing it won a 2026 Charter Award from the Congress for the New Urbanism, recognized in April 2026 for a detail that says everything about the incentive at work: the site was previously zoned for just 118 sprawling estate homes. Under the new plan, the Gill family's portion alone could produce up to 600 residential units, 420 of them deed-restricted and built by Teton Habitat for Humanity and the Jackson Hole Community Housing Trust, with 180 unrestricted units built for the free market. That's more units than Rafter J holds today in its entire 360-lot footprint, from one family's parcel alone. Add the neighboring Lockhart land, and county reporting has described the combined project as something that could become, over decades, Teton County's largest development ever.
This is the same mechanism that created Rafter J and Melody Ranch: a landowner trades open space or affordability commitments for the right to build more than the existing zoning allows. What's different this time is the scale, and the fact that it's landing on the doorstep of a neighborhood whose entire identity was built on the last two versions of that trade.
The unresolved friction: a road that depends on a neighbor who hasn't agreed to anything
Here's the part that should matter most to anyone evaluating South of Jackson today. The Gill family's traffic mitigation plan for their portion of Northern South Park includes bike lanes, sidewalks, and pathway connections built inside the new neighborhood, along with managed parking and transit access. What it doesn't guarantee is an east-west connector road that planners have wanted for at least 30 years, one that would give both future residents and construction vehicles an alternate route instead of funneling everything onto High School Road. That connector would need to cross land owned by the Lockhart family, the Gills' neighbors to the east, and the Lockharts have not submitted development plans of their own. Without their cooperation, county officials and conservation advocates have warned the new road segment could become a dead end serving only the Gill parcel, leaving High School Road and South Park Loop Road to absorb the bulk of the new traffic regardless.
That's a real friction point for anyone touring Rafter J or Melody Ranch this year. The neighborhood's two main access corridors are the same roads a Colorado traffic consulting firm projects will carry more than double their current volume, and the piece of infrastructure most likely to relieve that pressure depends on a second ranching family who has given no indication they intend to develop.
What this actually means for your timeline
None of this means change is imminent. In spring 2025, an attorney for the Gill family told county commissioners that the best-case scenario for breaking ground on the first phase was spring 2027, and that's only the opening phase of a project expected to unfold over decades. As of February 2026, a local housing advocacy group tracking the project reported that a formal development plan was still not yet public, and the Lockhart family, whose land borders the Gill parcel to the east, has submitted no development application of its own and has said it intends to keep ranching.
If you're buying in South of Jackson for the next five to ten years of ownership, you're most likely to experience this as a background hum: incremental construction traffic, a gradually changing mix of housing types to the north, and periodic public meetings about road funding. If your ownership horizon runs closer to twenty years, you're buying into a neighborhood that is scheduled to roughly double in scale next door, with the character of that growth still being negotiated block by block.
A few questions worth asking before you tour
Will Northern South Park change home values in Rafter J or Melody Ranch? Nobody can say that with confidence this early in a multi-decade build-out, but new deed-restricted and workforce housing supply immediately adjacent to an established, attainable neighborhood is not the same demand pressure as new luxury construction, and it's worth asking your agent how comparable additions have historically affected nearby resale patterns.
Does this affect Melody Ranch the same way it affects Rafter J? Melody Ranch sits further south on South Park Loop Road, so it's somewhat more insulated from Northern South Park's direct traffic impact, but it shares the same access corridor and would still feel any county-wide changes to how High School Road and South Park Loop Road are managed.
Is Rafter J's HOA involved in any of this? No. Rafter J's owner-run HOA and its separate water and sewer district govern only Rafter J's original 360 homesites. Northern South Park is a distinct parcel under its own county-approved plan, with its own future governance structure still being worked out.
If you're weighing South of Jackson against another part of the valley, the honest version of that conversation includes what's approved next door, not just what's for sale today. That's the kind of context Colby Murphy brings to a buyer or seller evaluating this corner of Jackson Hole, drawing on transaction history and local land-use tracking that goes well beyond what shows up in a listing description.
