Bellevue gets described the same way in almost every regional market writeup: flatter land, more of it privately held, and a lower price point than Ketchum or Sun Valley to the north. All of that is true. What the land story leaves out is that the reason new-construction lots in Bellevue city limits are hard to find right now has less to do with zoning maps than with a wastewater treatment plant.
Three separate development proposals covering more than 530 acres are currently working through Bellevue's approval process. Local reporting on the city's own council packets puts the spare sewer capacity at roughly enough for one of them, and that capacity is already earmarked for an existing subdivision.
What's Actually in the Pipeline
Here's what's on the table south of Main Street right now, according to Idaho Mountain Express coverage of recent Planning and Zoning hearings:
| Project | Acreage | What's proposed |
|---|---|---|
| Gannett Ranch | 191 acres | Annexation into Bellevue city limits, with early plans discussed at up to roughly 400 units |
| Moonlight Meadows | 148.93 acres | 26 lots on the west side of Gannett Road, with 30 percent of total acreage set aside as open space |
| Cove Springs North | 191 acres | Directly south of the existing Griffin Ranch subdivision, with the developer offering $179,115 toward community housing and $100,000 toward extending the Wood River Trail |
Combined, that's more than 530 acres and, if Gannett Ranch's own early figures hold, several hundred housing units trying to reach the market from a single stretch of land south of town. None of that acreage is hypothetical. All three are far enough along to have generated actual hearing dates, actual developer commitments, and actual pushback from Blaine County's Planning and Zoning Commission.
The Land Story Everyone Repeats
The regional framing is grounded in something real. In its March 2026 luxury housing report, Realtor.com placed Hailey among just 13 U.S. markets designated "pure luxury," a label reserved for places where more than half of active listings carry seven-figure price tags. As Yahoo Finance's coverage of that report laid out, the north end of the valley, where Ketchum and Sun Valley sit pressed against the Sawtooth National Recreation Area, has little room left for new construction, which keeps pushing prices on existing homes upward. The south end, where Bellevue and Hailey sit on flatter, more privately held ground, has more room to build.
The numbers from that same report back it up. As of March 2026, Hailey's median sat at $1.43 million with a 90th percentile of $5.2 million. Bellevue's median was lower, at $1.33 million with a 90th percentile of $3.13 million, and its median days on market, 73, was the fastest of the four Wood River Valley communities the report measured. More land, more building potential, faster sales at a relatively lower price point. That's the story, and it's accurate as a description of topography.
What the Land Story Leaves Out
Topography isn't the only thing that decides how fast entitled acreage turns into a house someone can close on. Coverage on Bellevue's own local news pages notes that the city's sewer system has capacity for roughly 400 more single-dwelling hookups, and that number is already tied to the Strahorn subdivision. The city has been pursuing a grant to expand capacity at the existing treatment facility.
The upgrade meant to solve that problem, a $9.5 million membrane bioreactor plant, was reportedly nearing completion when it ran into what local reporting described as a major setback. Until that gets resolved, the math is simple: three subdivisions representing 530-plus acres are competing for hookup capacity that's already spoken for.
That tension showed up directly in the Planning and Zoning hearings for Moonlight Meadows and Cove Springs North this past January, where commissioners pushed for water conservation conditions on top of the usual density and open-space questions. As Blaine County Recreation District Director Mark Davidson put it during one of those hearings, "as we grow as a community, demand for services grows."
Why Three Projects Can't All Clear at Once
Even setting the sewer question aside for a moment, the hearings themselves show how contested the terms of new supply have become. Blaine County declared an emergency water condition in summer 2025, and by the time the Moonlight Meadows hearing resumed this past January, low snowfall had already put 2026 on track for another shortage. That context shaped every negotiation at the table.
Cove Springs North's developer, Blackburn Farming, offered $179,115 toward community housing and $100,000 toward the Wood River Trail extension during hearings, a concession made without any impact fee ordinance requiring it. Moonlight Meadows' team argued the project already delivers a public benefit by building 26 units instead of the 29 allowed under an existing development agreement, while preserving 30 percent of its acreage as open space. Neither negotiation touches the sewer constraint directly. What they decide is who pays, and how much, if the county eventually adopts a formal development impact fee ordinance, something P&Z commissioners have pushed for and developers have resisted.
What This Means If You're Evaluating a Bellevue Lot
If you're looking at land or a new-construction lot in or around Bellevue, the acreage story and the utility story need to be checked separately.
- Ask whether the specific lot already has an allocated sewer hookup, the way Strahorn does, or whether it depends on capacity tied to a plant upgrade that hasn't been completed
- Ask where the Gannett Ranch annexation currently stands with city council before treating any marketing material about future neighborhood amenities as settled
- Ask whether a future development impact fee ordinance could apply to a project already under contract, since that question was still unresolved as of this year's hearings
- For parcels south of town, confirm water rights and irrigation district status independently of municipal sewer capacity, since Blaine County's 2025 emergency declaration targeted new permits for high-consumption uses separately from hookup availability
This is why Bellevue's price stability and its 73-day median time to sale, as measured in the March 2026 Realtor.com data, can coexist with more than 530 acres of proposed subdivisions sitting in city files. Entitled acreage and a certificate of occupancy are not the same thing. The number that decides how fast that gap closes is the one already sitting in the city's own reporting: roughly 400 hookups, one plant, three subdivisions asking for a share of it.
If you're weighing a lot in one of these Bellevue subdivisions or planning a development proposal of your own, the entitlement status and utility capacity questions are worth answering before the acreage story becomes the whole story.
