Buying Land in LaMoure County, North Dakota

No countywide zoning: 18 of 32 townships have adopted their own

LaMoure County does not regulate land use through a single countywide zoning ordinance. Instead, zoning authority sits with the county's 32 individual townships, and as of a late-2024 count published by the county, 18 of them had adopted their own zoning ordinances -- leaving the remaining 14 townships unzoned. This is structurally similar to how Cass County operates (covered elsewhere on this site), but the specific split is different: roughly 56% of LaMoure's townships have zoning rather than the more comprehensive township coverage seen in some other township-zoning counties, and this site did not identify a countywide subdivision ordinance or floodplain ordinance for LaMoure comparable to what Cass County runs directly.

For a buyer, this means there's no single "LaMoure County zoning code" to check. The applicable rule for an unincorporated parcel depends entirely on which township it sits in and whether that specific township is one of the 18 with an adopted ordinance -- and for a parcel inside any of the county's incorporated cities (LaMoure, Edgeley, Kulm, and others), zoning and building permits are a city matter entirely separate from county or township government. Confirm the township first, then check directly whether it has zoning and what that zoning permits.

The James River at LaMoure: an unusually flat, slow-draining river with a documented flood history

The James River, which runs through the center of LaMoure County, is genuinely unusual hydrology: it drops roughly 5 inches per mile of length, making it one of the flattest-gradient rivers in North America. That flatness means water moves through it very slowly, which can enrich floodplain soils over time but also means floodwaters recede gradually rather than rushing through -- and under high-inflow conditions, sections of the river have been documented to reverse flow for several miles. The City of LaMoure sits at a specific pinch point in the basin that local reporting has flagged as uniquely exposed to unregulated tributary inflow from smaller streams feeding the river south of Jamestown.

That exposure produced a documented, significant flood event in 2019: the James River at LaMoure crested at a record 15.95 feet in April, breaking the previous record of 15.80 feet set in 2010, then crested again at 15.12 feet that October following the wettest September in 125 years and an early blizzard that dropped over a foot of snow. Both LaMoure County and the City of LaMoure formally declared flood emergencies in mid-October 2019, driven in part by concern over increasing water releases from the Jamestown and Pipestem dams upstream in Stutsman County -- meaning river levels at LaMoure are shaped not just by local weather but by reservoir management decisions made elsewhere in the basin. Anyone buying property near the James River in LaMoure County should check current FEMA flood-zone maps and the river's gauge history directly rather than relying on a general sense of "it's a small, slow river."

Septic and environmental health: routed through the Central Valley Health District in Jamestown

LaMoure County does not run its own septic-permitting or environmental health department. It's one of eight counties -- alongside Barnes, Dickey, Foster, Logan, McIntosh, Stutsman, and Wells -- served by the Central Valley Health District, headquartered about 30 miles north in Jamestown. Septic (onsite wastewater) permits, inspections, and environmental health questions for a LaMoure County parcel go through that regional district, layered on top of the state-level licensing framework the state hub already covers.
