          "The Town's Highway Department, headquartered on the Smithtown Bypass, describes its own responsibility as maintaining \"more than 470 miles of roads, drainage systems, recharge basins, driveway aprons, and curbs\" — the town-owned local street network that is legally distinct from the state-owned NY 25, 25A and 347 corridors that cross the Town.[6]"

Town of Smithtown, a 2017 decision arising from a woman's fall on ice on a sidewalk or walkway in the Town's Charles Toner Park: the court held that \"[w]here, as here, a municipality has enacted a prior written notice law, it may not be subjected to liability for injuries caused by a defect\" absent written notice or a recognized exception, and affirmed summary judgment for the Town.[10]",
          "In a separate 2017 decision, Izzo v. Town of Smithtown, the Second Department revived a nuisance and trespass claim by the owners of commercial property in the Town's Kings Park hamlet, who alleged \"the Town wrongfully buried leaves and lawn debris under the surface of their property\" in the 1970s and 1980s; the court held that the continued presence of the buried material could give rise to successive causes of action under the continuing-wrong doctrine, rejecting the Town's argument that the claim was time-barred.[9]"
