What Nowthen's roads cost, and why

What Nowthen's roads cost

When the city asked residents what to fix, roads were the top answer. In the recent resident survey, road maintenance and infrastructure was the number-one service respondents said needed the most improvement. 129 named it, more than the next two answers (public safety, 64; community events, 49) combined. Asked which transportation improvement mattered most, road repairs and upgrades came first again, 96 responses to 30 for bike lanes and trails and 12 for “none, keep taxes low.” The written comments asked, often in the same breath, to keep the roads up and the gravel down. So: what does that actually cost?

What every city in the county spends on streets

Compared with every other city in Anoka County, Nowthen has a lot of road for the tax base behind it, and it already spends less to keep that road up than anyone else in the county.

Nowthen owns about 59 miles of road (MnDOT's count; the city's public-works page lists 61 miles, 25 gravel and 36 blacktop). Behind each mile stands only about $152,000 of tax capacity (the taxable value the city rate is charged on), the 4th lowest of 20. And across the last three audited years the city spent about $15,000 per mile on streets, the lowest of all 20, against a county median near $48,000 and Anoka at about $312,000 a mile. Some of that gap is fair: a rural gravel network is genuinely cheaper to keep up than curbed, lit, storm-sewered city blocks. But it also means there is very little slack. (Spending: MN State Auditor city finances, latest three audited years, operating plus capital. Tax base: DOR payable-2025 taxable net tax capacity. Miles: MnDOT.)

Reading the two columns: tax capacity per mile is how much taxable base stands behind each mile of city road. Lower means each mile has fewer tax dollars supporting it. Spending per mile is audited street spending divided by city-owned road miles; it isn't a road-quality score, but it shows the scale of the annual effort next to peer cities.

What a mile of road actually costs

A road mile is expensive to keep up because the cheap fixes only stay cheap if they happen on schedule: a timely crack seal is a fraction of an overlay, and an overlay is a fraction of a full reconstruction. Let a road slide past its window and the bill multiplies. MnDOT's own pavement-preservation guidance puts representative numbers on each treatment, per lane-mile:

A $3,700 crack seal or a thin overlay done on schedule can hold a street in good condition for decades; skip that upkeep and the same lane-mile eventually needs a reclamation or reconstruction costing roughly 15 to 150 times as much. That is the whole case for a road budget. (MnDOT representative costs, per lane-mile, from its Pavement Preservation Manual and Transportation Asset Management life-cycle guide; actual bids vary with width, traffic, and year. The full discussion is on the main roads page.)

Nowthen's 2026 road operating budget is $537,725 (public works plus the engineering line), about $9,114 a mile across its ~59 miles, every year. The city's half of the 2026 overlay project adds roughly $3,624 a mile spread over the network, for about $12,738 a mile, all in. There should be capital road projects every single year if the city is keeping up with maintenance of its roads, so this varying yearly amount is unavoidable if good roads is the goal.

For scale, a rural home pays about $1,135 a year in city tax (the average homestead at the certified 2026 city rate, the same figure the tax page uses). That one payment covers everything the city does (sheriff, fire, city hall, parks, and roads), and roads are only about 21% of the budget, so only roughly $244 of it does road work. At that rate it takes around 37 homes along a mile of street just to cover its yearly upkeep, and about 52 once the city's share of overlays is folded in. This low tax base per mile of road makes maintaining our road system more painful and more expensive to the average Nowthen taxpayer than in a place like Anoka, where housing is much denser, commercial is far more built out, and the tax base behind each road mile is much higher: about $315,000 a mile in Anoka against Nowthen's ~$152,000, roughly 2.1× as much. (What different kinds of new development do to that tax base is the subject of the cost of saying no.)

The projects, and how they're paid for

Most years the work is an overlay rotation: a handful of streets get a fresh surface before they fail, while others get crack-sealed to buy time and a few head toward full reconstruction. The streets on the list are nearly all past subdivisions. These are roads the city took on when those neighborhoods were platted, and now plows and repaves on its own dime:

On overlay and reconstruction projects Nowthen's practice, like most cities', is to assess 50% of the cost to the benefitting property owners and cover the other half itself, typically by issuing improvement bonds that are paid back over time through the levy and the assessments, not out of a single year's budget. Using the Pinnaker Lake Estates overlay as an example: that project ran 4,456 feet (about 0.8 of a mile) and assessed each of the 25 homes roughly $2,980, paid over about 10 years, with the city paying the rest. So homeowners do pay directly toward their own street's rebuild, but the split only covers those big one-time projects. The year-in, year-out maintenance, plowing, and gravel-road dust control still come straight out of the levy the whole town pays.

Gravel roads, and why they stay gravel

About 26 of Nowthen's ~61 miles are gravel (the city has counted them at 25–26 over the past year), not paved. Paving them all would be enormously expensive to build and then to maintain. A paved road will always require sealing, overlay, or other work, so a paved road is a guaranteed future capital expense for the city. For a low-traffic rural network of roads that primarily serve a few houses and carry little through traffic, gravel is usually the cheaper long-run choice.

Gravel is not free, though, and it does not stay put. The fine, clay-rich material that binds a gravel surface together is constantly lost: at the May 2026 budget work session, public works staff told the council that a vehicle traveling a gravel road at highway speed can strip about 1 ton of binding material per mile in a single season, and that progressive loss of clay content is what produces washboarding and loose, rutted surfaces. That is why the city has moved toward buying better gravel with a higher clay content that holds together longer. Placed Class 5 aggregate (the surfacing gravel the city buys) runs about $40–$52 a ton in recent city bids, and a gravel road needs that surface replenished again and again.

Hauling new gravel is where the cost really shows. With two trucks and a short summer season, city crews cannot keep pace, so the city increasingly hires it out. On a recent Basalt Street project, contractor Hass Trucking did in 3 days what would have taken city crews about 9 days, at a cost of nearly $20,000 for 3 days of hauling at $135 an hour plus materials. The council has discussed a phased gravel-road program on roughly a 3-year cycle, pairing contractor hauling with city grading.

On top of regraveling, the city grades the gravel roads and treats them sparingly with calcium chloride for dust control, concentrated on the worst or most heavily used stretches rather than blanketed across the whole network. The chloride pulls moisture from the air to hold the surface together and keep the dust down. It is also expensive: the 2025 dust-control program budgeted about $50,000 to treat just 9 segments, about 10 miles of the ~26 gravel miles, with bids of $50,560 (Northern Salt) and $69,700 (Envirotech), roughly $5,056 a mile. Applying it to every gravel road every year is simply not possible on the current budget, which is why most gravel miles go untreated in any given year. The year-by-year dust-control record is on the main roads page.

What spending more on roads would cost

Suppose the city wanted a clean $1,000,000 a year for roads (overlays and reconstruction). That money has to come from the levy, so paying for it means adding $1,000,000 to the levy, and that is true whether or not the tax base grows. A bigger tax base does not shrink the levy; it spreads the same levy over more property, which changes the rate and each owner's share, not how much the city has to raise. Run it through rate = levy ÷ tax base:

• $1,000,000 ÷ $9,197,371 of tax base = about 10.9 points added to the city tax rate.
• On the average Nowthen home that is roughly $521 more a year, about 46% on top of the ~$1,135 city share.
• Smaller steps scale the same way: every $100,000 of road work funded from the levy is about $52 a year on the average home.

This is not just a thought experiment. At the May 2026 budget work session the city's financial advisor laid out a plan to grow total street-improvement spending toward roughly $1,000,000 a year by about 2029, with improvement bonds issued every other year for the larger projects, the same order of magnitude as the figure above. That is the whole bind. The road budget is already the leanest in the county, so there is no slack to cut your way toward better roads. Which leaves two honest options: raise the levy and watch the average bill climb, or grow the tax base so more properties share the cost. Which kinds of growth actually help, and which just add more road to maintain, is the question the two companion pieces work through: pick two of three and the cost of saying no.

My take

Almost all the debate about how to keep Nowthen rural could be put to bed if the levy were raised enough for the city to catch up on roads. That is a tough sell. I would personally be willing to pay even $1,000 more a year in taxes if it meant Nowthen stayed exactly the way it is, but not everyone places that high a value on keeping it rural. The honest “cost” of not raising the levy significantly is one of two things: either development keeps being necessary to expand the tax base and the character of the city changes, or we keep living with underfunded, rough roads. There is no third door where the roads get better, the levy stays flat, and nothing gets built.
