How do you vacate a plat in Fremont County?

What vacation actually erases

A plat is a recorded map that creates lots, streets and easements; vacation is the procedure that erases it. Un-platting is the plain word for it: the recorded subdivision goes back to being un-platted ground, all of it or a named part of it. In Fremont County the procedure has two sources that move together, and the county’s code names both in its first sentence:

“Vacation of any plat, or any portion of a plat, may be proposed, following the procedure provided here and in I.C. 50-1306A”

— Fremont County Development Code, 2011 Edition (Ordinance 2011-04), section 3.39. Retrieved 5 October 2026

Why anyone files it is usually one of three stories: a decades-old paper subdivision that never built, whose lot lines now obstruct a sensible use; two platted lots an owner wants to make into one; or a platted street or easement that exists on the record and nowhere else. The starting document is the recorded plat itself — the subdivisions page explains how to find yours and what else the recording carries. One boundary fact first, because it decides the front door: under the statute, a petition to vacate goes to the city council if the plat sits inside a city, and to the county commissioners only in unincorporated county — which matters here more than most places, because a ribbon of US-20 through the middle of this caldera is itself an incorporated city, and platted ground inside that ribbon answers to the city, not to the county desk this page describes.

The county’s three findings, all mandatory

The Board of County Commissioners may accept a vacation only on findings, and the code lists them flatly. Three tests, each quoted from section 3.39.060:

Finding (c) is the one that ends most petitions. It is not a majority of owners and not the owners of the lots being merged — it is every owner of record of any property or property interest inside the plat, each consenting in writing. A single hold-out lienholder or an heir who never signed keeps the plat exactly where it is. And (a) and (b) extend past the plat’s own boundary — the protected access and utilities belong to separately owned land that was in, or is adjacent to, the plat, so the neighbours’ paper rights are findings, not courtesies.

The one-mile city gate

Inside a mile of an incorporated city, the city goes first. The county code states it as a hard stop on its own authority:

“…the County may take no action on a proposed vacation within one mile of an incorporated city until the vacation has been approved by the city”

— Fremont County Development Code, 2011 Edition (Ordinance 2011-04), section 3.39. Retrieved 5 October 2026

The statute works the same gate from the notice side — and adds the calendar:

“…the county commissioners shall cause written notice of the public hearing on the petition to be given to the mayor or chief administrative officer of the city by regular mail at least thirty (30) days prior to the date of public hearing.”

— Idaho Code §50-1306A(4), Idaho Legislature. Retrieved 5 October 2026

For Island Park ground this is not a technicality — the county’s unincorporated cabin country sits hard against a city that is itself a 34.8-mile strip along the highway. A vacation petition for ground near the ribbon can spend a month in the city’s inbox before the county’s clock even starts, and the city’s answer is a precondition, not a courtesy.

The procedure, meeting by meeting

Two bodies, two meetings, and one attendance rule. The county’s track, in the code’s own order:

1. Petition and fee filed with the Administrator, who places it on the agenda of the next regular commission meeting whose calendar allows proper review (3.39.010).
2. The Commission reviews and recommends acceptance or denial to the Board (3.39.020) — a recommendation, not the decision.
3. The recommendation travels: the Administrator notifies the Board and the petitioner within 10 business days, and unless the petition is withdrawn, sets the hearing for the next regular board meeting where notice can be met (3.39.030).
4. Notice goes out under section 3.29 — the same machinery the hearings page walks through, with the statute’s own mathematics underneath it (below).
5. The Board hears the petition, under a rule the variance page will recognise:

“No petition shall be reviewed if the petitioner or a representative is not present.”

— Fremont County Development Code, 2011 Edition (Ordinance 2011-04), section 3.39.050. Retrieved 5 October 2026

Then the decision on the findings above, and the Administrator notifies the petitioner and interested parties of it — again within 10 business days (3.39.060, 3.39.070).

What the statute adds

Idaho Code 50-1306A — last amended in 2024 — sets the notice arithmetic and two exceptions worth knowing. The mailed notice:

“Written notice of public hearing on said petition shall be given by first class mail, certified mail, or certified mail with return receipt at least ten (10) days prior to the date of public hearing to all property owners within three hundred (300) feet of the boundaries of the area described in the petition”

— Idaho Code §50-1306A(2), Idaho Legislature. Retrieved 5 October 2026

…plus publication once a week for two successive weeks in the official newspaper, the last at least seven days before the hearing — with the publication costs sitting on the petitioner (subsection 7). Then the exception that surprises people. For easements of the utility kind — gas, sewer, water, telephone, cable television, power, drainage and slope — public notice of intent to vacate is not required at all; instead, “all affected easement holders have been notified…and have agreed to the same in writing”, and the vacation happens by recording the new or amended plat (subsection 5). Same unanimity principle as the county’s finding (c), different cast: instead of every owner in the plat, every holder of the pipe and wire. The statute also keeps a short exit for the merely clumsy: land that was properly platted “need not be vacated in order to be replatted” (subsection 9) — sometimes the right filing is a redraw, not an erasure.

Partial vacation: the Mylar redraw

Erasing part of a subdivision creates a new document, and the code names the material it must be drawn on. Finding (d):

“…the petitioner will prepare a new plat drawing on archival Mylar of the amended subdivision, clearly noting those portions or parts of the subdivision vacated.”

— Fremont County Development Code, 2011 Edition (Ordinance 2011-04), section 3.39.060.d. Retrieved 5 October 2026

That drawing is “recorded immediately in the office of the Fremont County Clerk after being signed by the Board of County Commissioners” — the erasure and the replacement map reach the record together, so the county’s books never show a gap. Archival Mylar is the drafting-film standard for permanent records; a cousin procedure, amending a recorded plat rather than vacating one, has its own county requirements — the amendment page on the St. Anthony site carries them for the same county desk.

Before you petition

1. Pull the recorded plat and read it for owners of record — every one of them signs finding (c)’s consent, so the signature hunt starts at the parcel records, not at the hearing.
2. Map the neighbours’ dependencies first: any separately owned lot that reaches its road or its utilities across the plat is findings (a) and (b), and the petition must respect both.
3. Check the distance to the nearest city limits — inside a mile, budget the city’s approval and its thirty-day notice before the county calendar begins.
4. Decide between erasure and redraw with the statute’s own alternative in mind: a replat may accomplish the goal without a vacation at all.
5. Line up the drafter for the archival Mylar early; a partial vacation cannot record without the redrawn plat, and the Board’s signature is the last step of a chain that starts with the surveyor.
6. Then plan attendance for every meeting — the presence rule bars review without the petitioner or a representative, exactly as the permit path expects a body in the room.

Vacation is the county’s most consensus-hungry procedure by design: nobody’s access, nobody’s utilities, and nobody’s signature can be waived. The plats that erase cleanly are the ones whose owners were already aligned; the ones that were not stay on the record, exactly as recorded.

Common questions

What does it mean to vacate a plat?

It erases a recorded subdivision — the whole plat or a named portion — from the county's records, returning the ground to un-platted status. In Fremont County the procedure follows Development Code section 3.39 together with Idaho Code 50-1306A, ending in a Board of County Commissioners decision on written findings.

Who has to consent to vacate a plat in Fremont County?

Every owner of record of property or property interests within the plat proposed to be vacated, and the consent must be in writing — the code's finding (c). It is a unanimity requirement: one hold-out owner or interest holder keeps the plat in place.

Can the county vacate a plat next to a city?

Not on its own. The county may take no action on a proposed vacation within one mile of an incorporated city until the city has approved it, and the statute requires written notice of the hearing to the city's mayor or chief administrative officer at least thirty days in advance.

Does vacating a plat wipe out utility easements?

Not where they serve separately owned land: the county must find the vacation will not eliminate easements or rights-of-way used for utilities serving any separately owned lot in or adjacent to the plat. Utility-type easements (gas, sewer, water, telephone, cable, power, drainage, slope) can be vacated without public notice under the statute — but only with every affected easement holder notified and agreeing in writing, and by recording the new or amended plat.

How is a plat-vacation hearing noticed?

Under the county code's section 3.29 machinery — the same notice battery this site's hearings page explains — on top of the statute's requirements: mailed notice at least ten days ahead to all property owners within 300 feet, and publication once a week for two successive weeks in the official newspaper, the last at least seven days before the hearing, at the petitioner's expense.

Can you replat land without vacating it first?

Yes — Idaho Code 50-1306A(9) says land (exclusive of public right-of-way) that was subdivided and platted need not be vacated in order to be replatted. For a partial vacation, though, the code requires a new plat drawing on archival Mylar, recorded immediately with the County Clerk once the Board signs.
