The court rejected the applicability of the ongoing-storm rule, which arbitrarily relieves commercial landowners from any obligation to try to render their property safe while sleet or snow is falling. The court held a commercial landowner has a duty to take reasonable steps to render a public walkway abutting its property—covered by snow or ice—reasonably safe. The court imposed a duty of ordinary care and identified factors to consider when determining whether the landowner breached that duty, emphasizing that reasonableness is the polestar.
