How Long Does It Take to Plow a Parking Lot? Per Acre Math

How long does it take to plow a parking lot? With a pickup and a 98-inch blade, about 36 minutes for an open 1-acre lot in 2 inches of snow and about an hour in 6 inches, turns and stacking included; a 3-acre lot runs 70 minutes and 2 hours. No published rate says so; the number comes from blade width, speed by depth and the lot's shape.

How long does it take to plow a parking lot? It depends on the lot

Nobody publishes a plowing rate per acre, because the same acre takes a different time in 2 inches than in 8, and on an open lot than on one cut up by islands. BOSS Snowplow's productivity guide says commercial contractors typically target 1 to 2 acres per hour per truck on mixed lots; a target is not a quote.

Public bids show the spread: on a 2013 Missouri DOT tabulation for a state office lot, two bidders priced plowing plus melting agent applications for the 0.5 to 5 inch band at $2,200 and $600 per occasion. The bidder who knows the truck hours behind the number can defend it.

Step 1: Get the lot's square footage

Divide the square feet of pavement you will actually push by 43,560 to get acres. Trace the paved area only, leave out islands and curbed beds, and note the long dimension: passes and turns depend on which way you plow.

The free satellite measurement tool returns a lot's square footage from a traced outline, no account needed, and Cut out removes islands; in MakeHay the saved measurement fills a Per square foot line through Use in line (measuring help).

Step 2: Effective blade width at an angle

A blade loses width as soon as it is angled. BOSS Snowplow's guide puts a 98-inch V-plow (its DXT series, measured with the wings straight) at around 85 inches of effective width at a 30-degree angle, 7 ft per pass after rounding down; a straight blade or an expandable plow has its own figure. Then take off your own overlap: 6 inches of overlap on every pass leaves 6.5 ft, and that is the width that goes into Step 4 (the worked example keeps the round 7 ft).

Step 3: Speed by snow depth and lot clutter

Speed moves the answer most, and it drops with depth. Open lots with long runs sit at the top of a BOSS Snowplow band; lots with islands, light poles and curbs sit at the bottom.

Plan for the depth the weather record gives. NOAA's 1991 to 2020 normals list, per station, the average days a year with 1 inch or more of snow and with 3 inches or more (codes GE010TI and GE030TI): 11.4 and 3.9 days at Chicago O'Hare, and 1.4 days with 5 inches or more (GE050TI), so most snow days there stay under 3 inches, and a 2-inch trigger puts most pushes under 5 inches, in the 2 to 4 inch band at 8 to 12 mph or the 4 to 6 inch band at 5 to 10 mph (see the seasonal contract post).

In MakeHay, every scheduled visit carries the National Weather Service forecast for the lot's own coordinates, and the snow plowing setup suggests a rule named "Plow night", or "Snow event" for snow removal: max rain 50 percent and max temp 34°F (US addresses only; see the weather help article).

Step 4: Plow time per acre with passes, turns, stacking and a buffer

Plowing time is acres divided by real acres per hour, plus the turns, the piles and a buffer the formula does not see.

Snow plow productivity acres per hour, from the field capacity formula

The field capacity formula is acres per hour equals width in feet times speed in mph times field efficiency, divided by 8.25, and Iowa State's Ag Decision Maker derives 8.25 from 43,560 sq ft per acre and 5,280 ft per mile. BOSS Snowplow says to start at 60 to 80 percent efficiency until your own records say otherwise; 7 ft at 10 mph gives about 8.5 acres per hour before efficiency and roughly 6 after it.

Then add what the formula leaves out. BOSS counts 15 to 30 seconds per turn, 5 to 15 minutes per lot for stacking piles at the perimeter, and a 20 to 25 percent buffer. Passes are the lot's short side divided by the effective width, rounded up; turns are one fewer.

On the 1-acre lot at 2 inches the 28 turns (14 minutes) take longer than the straight runs (10 minutes), so a small cut-up lot can cost more per acre than a 3-acre open one; and 6 inches takes about 70 percent longer than 2, so price per push in depth bands.

Step 5: From truck hours to a per push price

A per push price is truck hours times a loaded hourly rate plus margin, with salt on its own line. O*NET's wages page for landscaping and groundskeeping workers, from 2025 Bureau of Labor Statistics data, gives a US median of $18.82 per hour ($14.98 at the 10th percentile, $27.28 at the 90th). The US Energy Information Administration prices on-highway diesel weekly: $6.199 per gallon for the week of October 5, 2026. The salt post prices the salt line.

Loaders, pushers and haul-off: when hourly beats per push

Per push pricing assumes the snow fits on the lot. When the piles have nowhere to go, or the depth sits in the bottom band at 1 to 5 mph, a loader takes over and the price goes hourly. A pusher box on a skid steer or loader clears a wider swath than a truck blade and bills by the hour the same way. The same 2013 Missouri DOT tabulation shows the shape: a loader with operator at $150 and $100 per hour, a loader and dump truck at $240 and $200 per hour, and a dump fee of $80 and $50 per load. Those are one US state's bids from 2013: use the structure, not the prices.

Sanity check against market ranges and your own logs

Consumer cost guides for homeowners quote driveways, not lots: Bob Vila's snow removal cost guide, updated January 2024, puts a plow visit at $30 to $50 for a driveway, with no per-acre figure for a lot. The 2013 Missouri DOT bids ran $600 and $2,200 per occasion for plowing plus melting agents in the 0.5 to 5 inch band and $100 and $150 per hour for an extra plowing trip, so the example's $89 per truck hour sits below both bidders: its truck and margin figures are lean, not generous.

Your own logs beat any table: for every push this winter, write down the lot, the depth, the minutes from first pass to last pile and the drive time; after a dozen storms you have an efficiency factor and a stacking time per lot.

Putting it on the quote

In MakeHay, the snow plowing starter list under Settings › Services carries "Commercial lot, per push" and "Driveway plow, per push" as Each items, "Sidewalk and walkway" as Per linear foot and "Pre-season stake and mark" as a Flat price. A request form with the "Job site address" question lets a property manager submit the lot, and a repeating job with Bill after each visit makes one invoice per push, each visit marked Done or Skip (repeating service help); the snow plowing software page shows the quote these lines make.
