Buying Land in Morton County, North Dakota
Home to Mandan, just across the Missouri River from Bismarck, Morton County carries two genuinely distinct, still-live land-use stories: it was the epicenter of the 2016-2017 Dakota Access Pipeline protests, whose legal and regulatory aftermath was only reaching resolution points as late as 2026, and it's currently in the middle of a contested data center zoning fight -- one that has already exposed a real gap between county and city zoning authority a buyer needs to understand.
The Dakota Access Pipeline protests: recent history, not settled history
The 2016-2017 protests against the Dakota Access Pipeline (DAPL), organized substantially around the Standing Rock Sioux Tribe's opposition to the pipeline's crossing under the Missouri River at Lake Oahe, were centered in Morton County, near Cannon Ball and along North Dakota Highway 1806. Law enforcement closed Highway 1806 for a stretch reported at roughly five months, and by mid-November 2016 more than 470 people had been arrested; a clash near the Oceti Sakowin encampment that November left hundreds treated for injuries. This was one of the most nationally and internationally covered land-use and Indigenous-rights conflicts in recent US history, and it played out substantially on Morton County ground.
What makes this directly relevant to a Morton County land buyer in 2026, rather than purely historical: the legal and regulatory fallout was still actively unresolved as recently as this page's writing. A Morton County jury found Greenpeace liable for hundreds of millions of dollars in damages to pipeline developer Energy Transfer in March 2025; the presiding judge finalized a reduced $345 million judgment in February 2026, which Greenpeace has said it will appeal to the North Dakota Supreme Court. Separately, on the pipeline's actual regulatory status, the US Army Corps of Engineers only signed a final Record of Decision granting the Lake Oahe easement in May 2026 -- nine years after the pipeline began operating under a more provisional status -- with added safety conditions, and the Standing Rock Sioux Tribe has said it will continue pursuing legal challenges. None of this points to a specific, identifiable land-use restriction on any given Morton County parcel, but a buyer should understand this history is current, not archival, and should ask directly about any pipeline right-of-way, easement, or protest-related land history if a parcel is anywhere near the Missouri River crossing area or Highway 1806 corridor.
Data centers: a pending ordinance, a moratorium, and a jurisdictional gap worth understanding
Morton County has been actively working through a data-center zoning question since imposing a moratorium on new data center and cryptocurrency mining facilities in September 2024, which barred such facilities from being permitted until the county developed formal siting and performance standards. As of August 2026, the county's Planning and Zoning Commission voted unanimously to recommend approval of a draft ordinance addressing noise limits, setback distances, water and power consumption, road impacts, and emergency planning for future data centers, with a county commission vote scheduled for consideration soon after -- meaning as of this page's September 2026 writing, the ordinance's final terms and adoption status should be confirmed directly with the county rather than assumed settled.
A specific, concrete illustration of why jurisdiction matters here: a data-center developer (reported as Sagebrush Infrastructure Partners) has already signed purchase-option agreements with three Morton County landowners for parcels that lie within the City of Mandan's extraterritorial zoning jurisdiction -- land that is physically in the county but zoned by the city, not the county. County officials have said directly that the county's pending data-center ordinance would have no effect on that specific land precisely because of this jurisdictional split. For any Morton County parcel a buyer is evaluating -- whether concerned about large industrial development nearby or considering such development themselves -- the first diligence step is confirming whether the parcel falls under county zoning or a city's extraterritorial zoning authority, since the applicable rulebook (and which government body to contact) genuinely differs.
Zoning and floodplain: a county-run Land Use Code with a Missouri River-specific overlay
For unincorporated Morton County land, the Department of Planning and Zoning directly administers the county's Land Use Code, covering zoning districts, subdivision regulations, setbacks and road approaches, and floodplain/stormwater management -- a single county-run system rather than a township-based patchwork. Notably, the Land Use Code includes a specific Missouri River Overlay District alongside its general Floodplain Overlay District, reflecting the county's substantial Missouri River frontage (the Heart River also flows into the Missouri at Mandan). The Planning and Zoning Commission meets monthly to review proposed changes and hear public comment, most recently working through both the floodplain rules and the pending data-center ordinance in the same cycle of meetings.
A buyer evaluating a specific unincorporated Morton County parcel should confirm its zoning district and, if it is anywhere near the Missouri or Heart rivers, whether the Missouri River Overlay District or the Floodplain Overlay District applies -- these are separate, specifically-named regulatory layers in the county's own code, not a generic "check for floodplain" caveat.
Who to Call Before Buying Land in Morton County
A verified direct phone number for the Morton County Department of Planning and Zoning specifically was not confirmed beyond a general courthouse line at the time of writing -- use the department website's contact form or the general courthouse number, (701) 667-3358, to reach the correct staff. Mandan and other incorporated cities in Morton County run their own separate planning, zoning, and building-permit departments -- and, as the data-center land-option situation shows, a city's extraterritorial jurisdiction can extend zoning authority onto county land beyond its formal limits, so always confirm which government body actually governs a specific parcel before relying on county contacts alone.
