Albany, N.Y. — New York homeowners face a generally low risk of sinkholes compared with many other parts of the country, but experts say subtle ground changes should not be ignored when they do appear.
According to the U.S. Geological Survey, most of New York does not sit atop widespread limestone or other highly soluble rock formations that commonly lead to sinkhole development. As a result, large-scale sinkhole activity is far less common than in states with extensive karst geology.
Geologists note, however, that low risk does not mean no risk. Isolated sinkholes can still occur, particularly in areas with localized limestone deposits, abandoned underground infrastructure, or where groundwater conditions change due to heavy rainfall, construction, or aging drainage systems.
Sinkholes typically develop slowly, even in low-risk regions. Experts emphasize that surface changes often provide early indicators of underground erosion or soil movement long before a collapse occurs.
Homeowners who encounter shallow depressions in yards, soil that feels soft or spongy, or unexpected areas of standing water are encouraged to take note. Cracks forming in sidewalks, driveways, patios, or foundation walls can also reflect subtle ground movement rather than routine settling.
Other signs may be easy to dismiss. Leaning fences, separating steps, tilting trees, or gaps opening between soil and concrete surfaces can sometimes point to localized ground instability rather than normal wear.
In New York, sinkhole-related concerns are more likely to be highly localized rather than widespread. Experts say risk can vary by neighborhood depending on soil composition, drainage patterns, and past land use.
The USGS cautions that when surface changes persist or worsen, homeowners should avoid filling depressions and seek evaluation from local officials or qualified professionals. Covering changes can hide developing issues and delay proper assessment.
Experts stress that awareness — not alarm — remains the best approach. Even in low-risk states, early attention to subtle ground changes can help prevent property damage and improve safety.
