Lincoln County's Community Plan Area Zoning System, Explained

Born in 2005, explicitly to slow down rural subdivision

Lincoln County's Community Plan Area system dates to 2005, and it wasn't adopted as a routine planning update -- it was a direct response to a rush of rural land subdivision in Star Valley that county officials and residents wanted to slow down. Rather than writing one countywide zoning map, the county organized Star Valley's individual unincorporated communities into separate Community Plan Areas, each with its own plan and overlay zoning, aimed at directing new development toward the existing town centers (Etna, Bedford, Alpine, and others) instead of letting it spread across open agricultural land. That history matters for a buyer: the system exists specifically to preserve open rural land outside the community cores, which is part of why its rules can feel more restrictive on undeveloped acreage than a typical single-map county zoning code.

Roughly seven named areas -- and the rules genuinely differ between them

Lincoln County's own planning materials identify Community Plan Areas covering Alpine, Etna, Freedom, Thayne, Upper Valley, a Multiple Use area, and the Star Valley Ranch Community Plan Area Overlay Zone (centered on the incorporated Town of Star Valley Ranch). Each area carries its own Rural Zone and, in some areas, Mixed Use designations -- and critically, the specific uses prohibited in a Rural Zone are not identical from one Community Plan Area to the next. Documented examples: both Thayne and Upper Valley prohibit truck stops in their Rural Zones, but Thayne additionally prohibits man camps outright, while Etna's plan separately restricts heavier industrial uses in its own Rural Zone alongside its own truck-stop and man-camp prohibitions. That means a Rural Zone designation by itself doesn't tell you what's actually banned on a specific parcel -- you have to know which Community Plan Area governs it and read that area's own use list.

The Star Valley Ranch Community Plan Area Overlay Zone carries its own specific dimensional standard worth knowing if you're looking at undeveloped acreage there: the minimum size for a new buildable parcel under that overlay is 35 acres, a meaningfully larger threshold than county's baseline rural residential expectations elsewhere, and one more piece of evidence for how directly the system tries to steer new building toward already-developed community cores rather than further subdividing surrounding open land.

Kemmerer doesn't use this system at all

It's worth being precise about geography here: the Community Plan Area system described above governs Star Valley communities in the northern part of Lincoln County. The Kemmerer area in the south -- served by the county's separate Kemmerer Planning and Engineering office rather than the Afton office that handles Star Valley -- runs on a more conventional zoning structure, and the City of Kemmerer itself maintains its own separate municipal zoning map for land inside city limits. If your parcel is anywhere near Kemmerer rather than in Star Valley, don't look for a Community Plan Area designation at all -- confirm the applicable zoning district directly with the Kemmerer office instead.

What to actually check for a specific Star Valley parcel

1. Identify which specific Community Plan Area governs the parcel (Alpine, Etna, Freedom, Thayne, Upper Valley, Star Valley Ranch, or Multiple Use) -- don't assume "Star Valley zoning" is one uniform rulebook.
2. Ask for that specific area's Rural Zone (or Mixed Use, where applicable) prohibited- and permitted-use list, since it genuinely varies by area -- a use banned in Thayne's Rural Zone may not be banned in a neighboring area's.
3. If the parcel falls under the Star Valley Ranch overlay, confirm the current minimum buildable-parcel size (35 acres as of this writing) before assuming a smaller lot can be built on.
4. Confirm which of Lincoln County's two Planning and Engineering offices (Afton for Star Valley, Kemmerer for the south) actually serves the parcel, and whether it's a Community Plan Area at all or Kemmerer's more conventional zoning.
