Researchers from Cornell University's New York Sea Grant-funded 2017 Coastal Flooding Survey Project targeted New York waterfront properties from May 25th - August 31st. They collected qualitative data about parcel location, severity of inundation, flood insurance, severity of erosion, damage to shoreline protection, and overall impacts.
In addition, pictures of the waterline and the property damage were provided by the respondents. Here are those photos, organized by Lake Ontario's shoreline counties:
Niagara County
Orleans County
Monroe County
Wayne County
Cayuga County
Oswego County
Jefferson County
