SEMINOLE COUNTY —
A sinkhole is causing problems Thursday in one Seminole County neighborhood.
Crews said the sinkhole is about 25-feet wide and is just inches behind a home on Lake Como Drive in Lake Mary. They have already started filling it.
The family who lived at the home left for safety reasons.
Neighbors said the home had a sinkhole in August. They said crews were fixing sinkhole problems associated with the first sinkhole when the second one opened up in the backyard.
The man who lives next door is hoping for the best.
“I’m hoping they are able to patch it and it stays right there and gets fixed. I hope it does not grow and is not under here as well,” said neighbor Vijay Mohan.
Sinkhole signs and causes
Sinkholes are depressions or a collapse of the land surface as the limestone below cracks and develops fractures. Acidic waters seeping through the soil lead to the breakdown over long periods of time.
While these types of events often occur after a high accumulation of rainfall in a brief period of time, they can also take place in extremely dry conditions, as the water table below the surface drops or dries out.
There are several signs you can watch for that may lead to the formation of a sinkhole:
- Fresh exposure on fence posts, foundations and trees that result when the ground sinks
- Slumping, sagging or slanting fence posts, trees or other objects
- Doors and windows that fail to close properly
- Ponding: Small ponds of rainfall forming where water has not collected before
- Wilting of small, circular areas of vegetation, because the moisture that normally supports vegetation in the area is draining into a developing sinkhole below the surface
- Turbidity in water in nearby wells
- Structural cracks in walls, floors and pavement
- Cracks in the ground surface.
