Two buyers can look at the same twenty acres south of Green River and walk away with two different plans. One assumes the trona boom means the parcel will be worth more in three years. The other assumes she can start building a shop and a house by next spring because the mine down the road means growth is already underway. Neither assumption is wrong exactly. It is just running on the wrong clock.
There are two separate timelines at play in land deals near Green River right now, and they move at very different speeds. One is the development timeline for the soda ash projects that have generated years of headlines. The other is the paperwork timeline: the disclosures, the title questions, and the access rules that determine what you can actually do with a parcel once you own it. Buyers who confuse the two tend to either overpay for growth that is still years out or skip questions that matter more than the mine ever will.
The clock everyone is watching
The excitement is real. Southwest Wyoming has two major soda ash projects working through permitting: Pacific Soda's Dry Creek Trona Project, about 20 miles southwest of Green River, and WE Soda's Project West, sited near Granger. Both would tap the trona beds that make the Green River Basin one of the largest natural soda ash deposits in the world.
But the timeline has moved since the earliest coverage. Here's the sequence as it actually stands:
- Early reporting on the Dry Creek project pointed to construction beginning in the first quarter of 2025.
- The Bureau of Land Management's Rock Springs and Kemmerer field offices issued a final environmental impact statement in February 2025, then a Record of Decision approving the project that May.
- In July 2026, the BLM issued right-of-way grant offers authorizing infrastructure construction, a real step forward but one that still depends on Wyoming Department of Environmental Quality permit approval and a reclamation bond before it takes effect.
- Sisecam, which now owns the Dry Creek project outright after acquiring its partner's stake in December 2024, has disclosed a revised timeline: construction is anticipated to begin in 2027, with commercial production targeted for 2030.
- Project West, the second major project, is currently expected to begin production even later, in 2032.
So the mine that has been "coming" since 2023 or 2024 is now, by the most recent disclosure available, still a year from breaking ground and four years from shipping product. That is not a reason to write off the projects. It is a reason to stop pricing land near Green River as if the boom already happened. Permitting milestones are genuine progress. They are not the same thing as trucks on site.
The clock nobody mentions until the closing table
While the development clock runs slow, a different clock starts the moment you make an offer on vacant land in Wyoming, and it has nothing to do with soda ash.
Wyoming law requires every seller of vacant land to give a prospective buyer a property disclosure statement, and one specific line item on that form asks whether the mineral estate has ever been severed from the surface estate in the chain of title. In plain terms: does the person selling you the surface also own what's underneath it, or did some previous owner sell or reserve the minerals separately, leaving you with a surface-only deed?
That disclosure line exists for a reason. Once minerals are severed, whoever holds them (or whoever they later lease to) generally has the legal right to access the surface to develop what's below it, with notice but not necessarily your permission. If you're buying twenty acres to build a home and a shop, that is worth knowing before you sign, not after.
A buyer can waive this disclosure. Plenty do, especially in a market where sellers and agents want to move quickly. Waiving it doesn't make the underlying question go away. It just means you find out the answer later, possibly from a landman knocking on your door instead of from a form you read at your own pace.
Split estate. But how split, really?
Here is where the advice gets murkier than most guides let on. Some sources describe mineral severance as close to universal in Wyoming, tracing it back to the Stock Raising Homestead Act of 1916, which allowed settlers to patent surface rights on stock-raising land while the federal government retained the minerals. Other sources describe severance as the exception rather than the rule, noting that a significant share of private land in the state remains unsevered, meaning the same owner holds both surface and minerals.
Both can't be fully right, and the honest answer is that it depends entirely on the specific parcel's chain of title. That is not something you can assume your way into, in either direction. It is something a title company can actually trace, back to the original land patent and forward through every conveyance since. If you're seriously comparing parcels near Green River, ask the title company directly whether the mineral estate is intact or severed on that specific tract, and don't accept a general statement about "how Wyoming usually works" as an answer.
The other line item that has nothing to do with minerals
Mineral status isn't the only thing that can quietly determine whether a parcel does what you want it to do. In the unincorporated parts of Sweetwater County, a residential construction project requires an approved zoning permit, and getting one depends on legal access. Land use officials will not approve a building permit unless the parcel abuts an approved county road or has a documented easement from a neighboring property owner who does have that access.
This matters more, not less, in exactly the acreage that trona-adjacent buyers tend to look at. The land drawing interest because it sits near the Dry Creek project or Project West is often farther from town, on private roads or shared access that were never surveyed with a homesite in mind. A parcel can look buildable on a map and still fail this test. Sweetwater County's Land Use Department handles zoning permits, and the county also issues a separate driveway and access permit for anything connecting to a county road. Confirming access before you're under contract costs you a phone call. Confirming it after closing can cost you the ability to build at all.
What this means before you write an offer
Three questions are worth asking on any acreage parcel near Green River, before price ever enters the conversation:
- Ask the title company directly whether the mineral estate has been severed on this specific tract, and get it in writing rather than relying on a general statement about how common severance is in Wyoming.
- Read the property disclosure statement line by line, and if mineral severance disclosure was waived, ask why, and consider ordering a mineral title search yourself before closing.
- Confirm legal access to an approved county road, or a recorded easement, with the Sweetwater County Land Use Department before assuming the parcel is buildable, especially on acreage that sits well outside town.
The trona projects near Green River are real, well-documented, and moving through federal permitting on a public record anyone can check. But the most current disclosures put construction in 2027 and commercial production in 2030 for Dry Creek, with Project West further out still. Plan your purchase around what the title company and the county can confirm today, not around a headline that was accurate two years ago.
Does buying land near Green River always mean the mineral estate is severed? Not necessarily. Sources disagree on how common severance actually is across Wyoming, which is exactly why a parcel-specific title search matters more than a general rule.
Can I still buy land if the minerals were severed long ago? Yes. Many Wyoming landowners live comfortably on surface-only deeds. The point isn't to avoid severed land, it's to know before closing so you understand what access rights the mineral owner may have.
If the trona projects are years away, does that mean land near Green River isn't a good buy right now? That's a separate question from disclosure and access, and one that depends on your goals and timeline, not a press release.
Land near Green River asks more of a buyer than most listings let on, and that's exactly the kind of groundwork Forever West Land & Home walks clients through before an offer ever goes in. If you're comparing acreage in this part of Sweetwater County, let's connect and talk through what a specific parcel's title and access actually look like.
