How often should a parking lot be plowed during a snowstorm?

It depends on accumulation rate, operating hours, and property type. Many lots use a 1 to 2 inch trigger for the first plow pass, then continue service during the storm if snow is falling fast enough to affect access or visibility. High-traffic facilities may need near-continuous clearing to keep entrances, ADA areas, and pedestrian routes safe.

What is the best de-icer for a parking lot?

There is no single best product for every site. Rock salt works well in many conditions but loses effectiveness at lower pavement temperatures, while liquid brines and chloride blends can perform better when timed correctly. The right choice depends on temperature, pavement type, traffic, corrosion concerns, and budget.

Who is liable if someone slips in a snowy parking lot?

Liability can involve the property owner, parking operator, management company, snow contractor, or a combination of parties depending on the contracts and the facts of the incident. Courts and insurers typically look at whether the hazard was foreseeable, whether reasonable inspections were performed, and whether service records show prompt action.

How do you keep a parking lot from icing over again after plowing?

The key is to manage refreeze, not just remove visible snow. That means treating problem areas after plowing, monitoring meltwater from snow piles, keeping drains open, and reinspecting shaded or low-lying spots as temperatures drop. A follow-up check later the same day often prevents black ice overnight.

Should snow be piled on-site or hauled away?

On-site storage is usually less expensive, but it only works if piles do not block sight lines, reduce too many spaces, cover drains, or create runoff that refreezes. Hauling becomes the better option when storage areas are limited, storms are frequent, or pile placement starts affecting safety and revenue.
