When one walks the streets, sidewalks, and parking lots of New York and Long Island, they may be walking on property owned by the city or town. Like any other property owner, municipalities are responsible for keeping their property reasonably clear of hazards, including snow, ice, water, oil or other slippery substances, and cracks, depressions, and potholes. If any property owner knew or should have known about a hazardous condition, they can be held responsible for damages based on negligence. Municipalities are no different.
