The Windrow: The Snow Ridge the City Plow Leaves at the End of Your Calgary Driveway

It might be the most frustrating moment of a Calgary winter: you finish shovelling the driveway, and an hour later the City plow rolls down your street and leaves a ridge of dense, chunky snow across the end of it. That ridge has a name — the windrow — and it is nobody's favourite chore, because it is the worst snow on the property to move.

What a windrow is and why it happens

When the City's road plows clear residential streets, the blade pushes snow to the curb — and across every driveway apron in its path. The result is a compacted berm, often mixed with sand and gravel from the road, sitting exactly where your car needs to exit. The City clears the roadway; it does not clear private driveways, so the windrow on your apron is yours to remove.

Windrow snow is heavier than fresh snow for two reasons: the plow compresses it as it passes, and it often sits through a freeze-thaw cycle before you touch it, turning the bottom layer into consolidated ice. A ridge you could kick apart in December can need real shovelling in January.

Who is responsible for windrow removal in Calgary

• The City clears roads, not driveways — snow pushed to the curb line stays there as part of road clearing.
• The property owner clears the apron. The driveway is private, so the windrow it inherits is the owner's job.
• The sidewalk is a separate obligation. The 24-hour rule with fines starting at $250 applies to the sidewalk bordering your property — here is exactly what the bylaw requires — and a plow event can refill it too.

How to remove a windrow without wrecking your back (or your car)

1. Get it early. Freshly plowed windrow snow breaks apart far more easily than windrow snow that has sat through a chinook and refrozen. Clear the same day if you can.
2. Push, do not lift. Windrow chunks are dense and loaded with grit. Pushing them onto the boulevard with a wide shovel spares your back; lifting repeated 10 kg chunks does not.
3. Watch for the ice layer. The bottom band is usually bonded to the pavement. Break it with the shovel edge before trying to lift it in slabs.
4. Do not throw it back into the street. Returning snow to the roadway creates a hazard and, after the plow's next pass, simply a bigger windrow.

How a snow removal contract handles windrows

This is one of the quiet differences between contracts. With seasonal service from Somerset Lawn and Snow, windrow removal is part of the visit: crews clear the driveway including the apron, so the ridge left by the plow is gone by the time the next vehicle needs to leave. With per-visit service — which starts at a $50 minimum (+GST) — the windrow is usually what pushes people to call, and during multi-day plowing events you can end up paying for it twice.

It is also a timing problem. City plows run their own schedule, so a driveway cleared at 7 am can be windrowed again by 9 am. Contract routes run through the season, and dense SW Calgary routing is what keeps repeat visits affordable — flat seasonal pricing starts at$90/month for sidewalk-and-walkway service, $145/month for a standard 2-car driveway.

Does the City of Calgary remove windrows from driveways?

No. City snow crews clear the roadway; the snow ridge they leave across a driveway apron sits on private property and is the owner's responsibility to remove.

Why is windrow snow so much heavier than regular snow?

The plow blade compacts it as it passes, and it usually contains road sand and gravel. After a freeze-thaw cycle the bottom layer consolidates into ice, which is why windrows get harder to move the longer they sit.

Do snow removal contracts include the driveway apron?

Somerset's seasonal service clears the full driveway including the apron, so plow windrows are removed as part of every visit. Always confirm apron coverage when comparing contracts — some companies clear the pad but stop short of the street edge.
