Snow stakes and markers: why and where

What are snow stakes actually for?

They show edges and hazards that disappear under snow. Carroll County, Maryland, whose road crews place stakes along county roads, describes the purpose plainly: to help snowplow drivers identify the edge of the roadway and to reduce property damage to residents' yards, and also to mark storm drain pipes. A private property has the same needs on a smaller scale.

The Town of Orange, Connecticut, makes the same point in its winter advisory: in heavy snowfall it is difficult to tell the edge of the pavement from the edge of a lawn, and stakes along property edges help homeowners avoid lawn damage, especially where there are underground sprinklers or invisible pet fencing. Western Montana properties add gravel drives, which have no hard edge for a blade to find even in daylight.

How tall should snow stakes be?

Tall enough to stand above the snow and the banks that build up beside a cleared surface. The Town of Orange's guidance is stakes 30 to 36 inches high, with the top 3 inches of wooden stakes painted red for visibility against snow. That is a reasonable starting point for most valley-floor drives here.

Use taller stakes where banks grow tall: along a long drive where snow is stored at the edges, on exposed ground that drifts, and on higher properties that get more snow than the valley floor. The Western Regional Climate Center's summary for the Missoula airport station shows mean annual snowfall of 45.3 inches; banks beside a drive collect far more than a single storm's depth over a season. A stake that is buried by February is not doing its job when it matters most.

When should stakes go in?

Before the ground freezes. The Town of Orange advises installing them early, before the freeze, and anyone who has tried to drive a stake into frozen ground in December knows why. In the Missoula and Bitterroot valleys, the hard freeze often comes before the first lasting snow, so the practical window is fall, alongside the other jobs that need the ground visible: irrigation winterization, fall cleanup and leaf removal.

Putting them in early also means you can see what you are marking. An irrigation head, a light fixture or a culvert end that is plain in October can be impossible to find once leaves and the first snow cover it.

Where should stakes go along a driveway?

Along both edges, set just outside the surface so they mark the edge without being in the path of the blade or a vehicle. Orange's guidance is to place them as close to the pavement as possible without interfering with traffic. Spacing depends on the drive: closer together on curves, at the bottom of slopes, at the entrance and wherever the edge drops into a ditch, further apart on a straight run with an obvious line.

Gravel drives need them most, because a blade that wanders off a gravel edge peels turf and drops stone into it. Our guide to plowing a gravel driveway explains why the edge matters so much. Paved drives still benefit, especially where the lawn is at the same level as the pavement or where landscape lighting runs along the edge.

What else on the property needs a marker?

Anything that will be hidden and could be struck or buried. On most properties that list includes irrigation heads and valve boxes near surfaces that get cleared, low-voltage landscape lighting, bed edging and borders, young shrubs and trees close to the drive, culvert ends and drain grates, curbs and parking blocks, well heads, septic risers and the edge of the septic drainfield, propane tank lines, and the corners of retaining walls.

The Minnesota Pollution Control Agency's snow storage guidance adds one more: mark the edges of both the plowing area and the snow storage area so equipment does not damage them. If you have agreed where snow should be piled, mark that too. Our guide to where to pile snow explains why septic areas, drains and beds should stay clear.

What about fire hydrants and mailboxes?

Hydrants near a drive or lot should be marked if there is any chance of burying them, and many already carry a flag or marker from the water utility. The City of Missoula tells residents not to cover hydrants with snow because firefighters and Missoula Water crews need quick access.

Mailboxes are visible, but the post and the approach are not. Our guide to mailboxes, hydrants and snow clearing covers clearance around both and what the Postal Service asks of customers.

Should you move the county's stakes to your driveway?

No. Where a road agency places its own stakes along a road, they are there for the road plow. Carroll County specifically asks residents to keep county-placed stakes in their original placement and not to remove them or transplant them to private driveways. If you think a road stake is missing or damaged, contact the road department that placed it.

Your own stakes should be on your own property and should not stick into the road or the travel lane. If your drive meets a county road, keep entrance stakes back from the road edge so the county plow does not take them out.

How is marking a parking lot or private road different?

The list gets longer and the stakes matter more, because more people use the surface and more equipment works it. On a commercial lot, curbs, islands, parking blocks, light pole bases, drain inlets and the edges of landscaped beds all disappear under snow, and a plow that finds a curb the hard way damages both the curb and the blade. Mark islands at their ends and corners, not just along their length, because the corners are what get clipped. Our parking lot snow plan guide covers the rest of a lot's winter layout.

A shared private road needs its edges marked along its whole length, plus every culvert, cattle guard, gate post and drop-off. Because several households and sometimes several contractors use the same road, agree once on where the stakes go and who maintains them. Our guide to private road snow plowing responsibility explains how neighbors usually share the work.

Why do stakes matter more in a western Montana winter?

Because the snow rarely leaves quickly. On the valley floor, monthly mean snowfall at the Missoula airport station peaks in December and January, with more in February and March, and every storm that is cleared adds to the banks beside the surface. The edge you could see in November is under a growing ridge by midwinter, and drifting on open benches moves that ridge around.

Freeze and thaw also make mistakes more expensive. A blade that drops off a gravel edge onto soft ground in a midwinter thaw tears up turf that cannot recover until spring, and a buried irrigation head that is hit while frozen cracks rather than bends. Stakes that are visible all winter are what stop those small errors from adding up.

What kind of stakes work best?

Most hardware and farm stores sell fiberglass driveway markers with reflective tops, and plain wooden stakes work if their tops are painted. What matters is that they are visible against snow and at night, flexible or cheap enough that a glancing hit does not cause damage, and firmly set so wind and passing snow do not knock them flat. Reflective tops help most at the times snow is actually cleared: early mornings and during storms.

Avoid metal rods or rebar near a drive. They are hard to see, they damage equipment and tires, and they become a hazard to anyone walking when they are knocked flat and buried.

What should you do with stakes in spring?

Pull them once the snow is gone and the ground has thawed, before mowing starts. Note any that were hit or buried, because those are the spots where the edge needs more markers or where storage should change next winter. Store them in one place and the next fall's job takes a fraction of the time. A spring snowmelt yard cleanup is a good time to check the lawn edges and beds along the drive.

The NWS snow measurement guidelines mention that snow depth is sometimes read at a permanently mounted snow stake. A single marked depth stake in an open part of the yard, away from drifts and trees, is also a handy way to see whether a storm reached your trigger depth.

Do we mark properties on our route?

Marking is part of setting a property up for the season. The walk-around before winter is when we settle trigger depth, snow storage and what is under the snow, and on managed properties the crew that blows out the irrigation and does the fall cleanup is the one that marks the heads, curbs and drain grates the plow needs to avoid. See our residential snow removal and HOA snow removal pages, and the full range of snow and 24-hour storm services. Snow plow damage prevention covers what gets hit most often. This guide is part of our Montana Winter Property Guide.
