Winter service in Bismarck

Same snow as Fargo. Different ground entirely.

The expectation about Bismarck is that it is the drier, colder, windier end of North Dakota — the western half, where the plains harden. The normals do not support any of that.

On the 1991–2020 normals Bismarck Municipal Airport records 50.5 inches of snow a season. Fargo, 300 kilometres east on the same table, records 51.4. Nine tenths of an inch apart — and Bismarck has more days with measurable snow, 44.6 to 41.8. Nor is it colder: Bismarck’s January daily mean is 12.8 °F against Fargo’s 8.6 °F, more than two degrees Celsius warmer. On wind, Fargo leads in every month of the same national table.

What is genuinely different is the ground under the snow.

Bismarck sits on the east bank of the Missouri at 1,745 feet. Fargo sits at 906. That is 839 feet — 256 metres — between two cities in one state. Fargo lies on the bed of glacial Lake Agassiz, which is why its page is about flatness and wind. Bismarck lies in the Missouri trench on the Coteau Slope, where the land rolls and the streets run up and down it.

You do not have to take that from a map. It is in the City’s own operating document. Bismarck’s Snow and Ice Control Plan opens its priorities with a category that a flat-country plan has no use for:

PRETREATMENT OF EMERGENCY ROUTES AND MAJOR ROUTES, BRIDGES, AND STEEP GRADE STREETS WITH LIQUID ANTI-ICING SOLUTION

Bridges, steep grades and intersections, treated before the storm. Fargo’s winter plan has no steep-grade category, because Fargo has no steep grades.

The pre-treatment decision is made from a forecast rather than from snow on the ground: staff analyze the National Weather Service predicted air temperature, dew point, relative humidity, predicted snow volume, wind speed, rain and freezing rain potential, and go out if conditions favour ice bonding to the road. That is anti-icing in the proper sense — getting a barrier down before the bond forms, rather than breaking it afterwards.

The season has its weight at the edges

The second real difference is distribution. The same seasonal total lands across more days, and it does not peak where you would expect.

On the monthly normals: December 10.1 inches, January 8.9, March 8.5, November 8.0, February 7.5. Read that order again — November and March both out-snow February. Bismarck’s winter is heaviest at its ends.

The storm record says the same thing more forcefully. The three best-documented events are 2–4 March 1966 (43 consecutive hours of blizzard conditions, gusting to 64 mph at the airport), 4–7 April 1997 (a further 17.5 inches with winds to 65 mph, pushing that season to 101.4 inches and setting the seasonal record that still stands) and 12–14 April 2022. All three are spring storms by the calendar.

And an average season is a poor description of any given one. Across 140 years of record the range runs from 13.6 inches to 101.6. The snowiest three seasons on the list are 1996–97, 2022–23 and 2008–09 — two of the three within living memory of anyone now running a route.

What matters more than the total: it does not thaw

Here is the number that shapes the work. Across a normal December, January and February, the daytime maximum fails to rise above freezing on about 57 of the 90 days.

Nothing melts off in between. What falls stays where it is put until a machine moves it, and what refreezes stays frozen. January’s mean high is 23.2 °F; the NWS record low for both January and February is −45 °F.

That is why Bismarck’s spreader is a sand truck. The City keeps a sand stockpile and states it strives

to obtain an eight percent (8%) salt content in this sand. The salt will keep the sand from freezing so it can be loaded and spread more efficiently.

Read what that says: the salt’s stated job in the mix is to keep the pile workable, not to melt the road. Rock salt is stockpiled separately, “for application as conditions warrant its use”. For much of a Bismarck winter the realistic goal is traction, not melting — the same physics that puts beet juice on the trucks in Rockford, answered with a different tool.

The sanding operation is staffed for it: 14 truck sanders, a two-person crew reporting at midnight through the winter, and someone reachable around the clock with authority to call in whatever help is needed.

How the city gets plowed

Bismarck is divided into seven plowing sections, each worked by a motor grader, a loader and a sander truck — the grader being another quiet sign of the terrain.

The priorities are ordered, and each has a number attached:

• Priority 1 — snow emergency routes. The signed grid that keeps police, fire and ambulance able to reach every part of town. Plowing here generally starts once about 2 inches have accumulated.
• Priority 2 — school routes and major routes, plus the streets around fire stations, hospitals and other emergency services.
• Priority 3 — residential and downtown streets. Residential streets are generally plowed if four or more inches have fallen, and under most conditions cleared within 24 to 36 hours of the storm ending.
• Priority 4 — the sidewalks Public Works owns.

That four-inch figure is worth keeping separate from Fargo’s. In Fargo, four inches in a forecast is what legally defines a snow emergency. In Bismarck it is an operational trigger for sending plows down residential streets. Same number, entirely different function.

Downtown is handled by hauling rather than pushing. A front-end loader moves snow into the parking lanes, and — this is the part worth knowing if you have a business there — the City then encourages downtowners to clean their sidewalks at this time and move that snow into the parking lanes, where it sits until it is blown into trucks and hauled away. A timed, deliberate exception to the general rule against putting snow in the street.

The ordinance the citizens wrote

Every plow city has the same argument about the ridge of snow left across the end of a driveway. Bismarck settled it, and the settlement is in the code.

At the end of § 10-02-05:

The City of Bismarck shall use snow gates or other devices to prevent snow, in an amount that prevents usual access, from being plowed or placed into driveways or their openings to public streets. This section shall cover City employees and contract employees. Any additional costs caused by this ordinance shall be paid by the City Sales Tax of the City of Bismarck.

The amending note reads Ord. 5294, 06-13-00, Initiated Ordinance — the residents put it there themselves, and specified how to pay for it in the same breath.

The contrast with Rockford is exact. There the city answers the same complaint by pointing to more than 60,000 curb cuts and calling individual clearing cost prohibitive. Same problem, opposite resolution, both defensible — and a good illustration of why a local page has to be researched rather than templated.

There is one carve-out, and it is the one that catches people:

This ordinance shall not apply in the event of a snowfall of such magnitude that a snow emergency is declared.

Which is why the City states flatly, in its winter FAQ, that during an emergency snow gates will not be used. When the declaration comes, speed replaces courtesy.

The sidewalk rule, and the unusual thing in it

§ 10-03-04 puts the duty on the abutting owner:

1. The owner of any lot or parcel of land abutting any sidewalk shall: a. Keep the sidewalk clean and unobstructed at all times. b. Remove snow and ice within 24 hours after the snow falls or ice forms, and keep the sidewalk free of ice and snow. Sand may be used to make the area safe for pedestrian travel if removal of ice is impracticable.

Two things stand out.

First, the code and the City say the same thing. That sounds unremarkable until you have read a few of these: in Fargo the ordinance sets a daily 9 p.m. deadline while the City’s own guidance describes a 24-hour clock, and in Bangor the City has announced a winter parking policy the code has not caught up with. Bismarck’s two surfaces agree.

Second, and more interesting: the code permits sanding instead of clearing where removing ice is impracticable. For a city with 57 days of continuous frost in a normal winter, that is realism written into law rather than a loophole. It also creates a small documentation problem for anyone doing this commercially — “we sanded because the ice would not come off” is a defensible position, but only if somebody wrote down the conditions at the time.

The City adds one point the code text leaves implicit: the duty covers the crosswalk of corner lots. A corner property has the crossing to clear too.

Snow may not go the other way either. § 10-03-04(3): A person may not move, dump or deposit by any means any snow or ice accumulated on private property onto any public street, alley, or public right-of-way — with the narrow exception for posted street-cleaning areas that makes the downtown practice above lawful.

What happens if it does not get cleared: a lien, not a ticket

Bismarck’s answer to “and what if I don’t?” is unusual, and worth setting out because almost nowhere explains it.

The ordinance sends the consequence to state law: costs are assessed to the abutting property pursuant to Chapter 40-29, N.D.C.C. That chapter runs an annual cycle:

• § 40-29-18 — if snow and ice are not removed as the municipality’s ordinances require, they may be removed under the street commissioner’s direction and the expense charged against the abutting property. Annually, on or before May first, the commissioner files a list showing the amount charged against each lot.

• § 40-29-19 / § 40-29-20 — notice is published once a week for two consecutive weeks, the last not less than eight days before the hearing, and the governing body considers and confirms the list at its regular June meeting.

• § 40-29-21 — once confirmed, the assessment with interest and penalties

  shall be and remain a permanent lien upon the property upon which the assessment is levied until the assessment is paid in full, and it shall have precedence over all other liens except general taxes.

So an uncleared sidewalk in January is not a citation. It is an entry on a list filed in May, confirmed in June, attaching to the property ahead of every other lien but the tax bill. This is a description of the published statute, not legal advice.

Snow emergencies: no threshold, 50 routes

Bismarck’s snow emergency is a judgement call written as one. § 10-02-03:

When the director of public works or designate determines on the basis of existing weather conditions or a forecast by the U.S. Weather Bureau that a snow emergency declaration is necessary it must be broadcast by local radio and television stations and announced in the official newspaper when feasible.

No number anywhere in it. The City describes the decision in practice as taken by the City Administrator with the Director of Public Works and the Chief of Police. And it ends the same way it begins — until terminated or modified by the director of public works by public announcement.

The prohibition is also narrower than Fargo’s city-wide sweep. It applies to designated snow emergency routes, of which § 10-02-01 names exactly 50, each required by § 10-02-02 to be signed at one sign per block or at least every 1,000 feet. The declaration lists the affected routes, or states that it covers all of them.

Once declared, it is illegal to stop or park on any affected route. A stalled vehicle buys its driver half an hour to arrange removal; a vehicle left in violation may be impounded by the police department. The code also carries an evidence rule that is rarer than it should be: proof that the vehicle was parked in violation and that the defendant was the registered owner gives rise to a rebuttable presumption that the owner parked it.

Beyond that, § 10-02-05 lets the director post streets for no parking and tow to clear them, buy goods and services outside the normal procurement rules, and hire temporary snow removal staff — each reportable to the City Commission afterwards.

When the city’s snow closes the state

One consequence Bismarck carries that no other North Dakota city does: it is the capital, and the North Dakota State Capitol — a 19-storey Art Deco tower, the tallest building in the state — sits on the rise north of downtown.

When the city declares a snow emergency, state government stops. After Bismarck declared one effective 7 p.m. on 12 April 2022, the Capitol and other state facilities in the Bismarck area stayed closed until 8 a.m. on the Thursday. The same happened on 10 November 2022 as travel conditions deteriorated across almost the whole state.

The river in winter

Bismarck’s river problem arrives in the middle of winter rather than after it.

On 29 February 2024 an ice jam near Fox Island and the mouth of the Heart River, just south of the city, pushed the Missouri to 14.92 feet, over the minor flood stage of 14.5. The Army Corps of Engineers cut releases from Garrison Dam from 25,000 to 22,000 cubic feet per second with a further reduction to 19,000 planned; the Governor issued an emergency order covering both Burleigh and Morton counties and activated the State Emergency Operations Plan; and the North Dakota National Guard flew a Blackhawk with a Bambi Bucket to drop 660 gallons of river water — around 5,000 pounds — onto the jam’s leading edge.

A regulated river, two counties, a helicopter, in February. Fargo’s river event is a spring melt; this is not the same problem at all.

Across the river, and around it

Mandan sits directly opposite on the west bank — a separate city in a different county, Morton rather than Burleigh, with its own public works and its own ordinances. Lincoln lies to the south-east in Burleigh County. The crossings between Bismarck and Mandan, including the Grant Marsh Bridge carrying I-94, are exactly the exposed decks the City’s plan pre-treats.

Everything on this page describes Bismarck. Cross the Missouri and the rules, the priorities and the phone number all change.

Recording a winter measured in judgement calls

What is distinctive about Bismarck’s rules, taken together, is how much of the winter runs on a decision rather than a number. Whether to pre-treat is a forecast call. Whether to declare a snow emergency is explicitly a call by named officials, with no inch threshold. Whether an owner may sand rather than clear turns on whether removal was impracticable — a judgement, made on a specific morning, about specific ice.

Judgement calls are exactly what nobody can reconstruct three months later, and in Bismarck the consequences do arrive three months later: the assessment list in May, the hearing in June.

Wintertrace is self-hosted software for recording winter service work — what was cleared or treated, when, by whom, with which material, with the weather conditions of the shift attached, producing a service record afterwards. It runs on your own hosting, without a subscription, and the data stays with you. For a contractor working sanded routes under a 24-hour rule on ground that includes graded streets and river bridges, the useful artefact is a timestamped record of the call that was made and the conditions it was made in.

A note on all of the above

This page is general information about winter service in Bismarck, North Dakota, drawn from the City’s published Snow and Ice Control Plan, its Code of Ordinances and the North Dakota Century Code as of August 2026.
