Prevention & Treatment: Do not plant beans in low-lying, poorly drained areas. Plant beans on raised beds. Plant after the soil has warmed to 69 Â°F at a 4-inch depth. Reduce disease buildup in the soil by rotating locations in the garden where you plant bean or pea with other vegetables.
These collapses can be small, or, as this picture shows, or they can be huge and can occur where a house or road is on top. The most damage from sinkholes tends to occur in Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania. The picture to the left shows a sinkhole that quickly opened up in Florida, apparently eating a swimming pool, some roadway, and buildings.
Causes of Sinkholes Around Drainage Structures. The most common cause of sinkholes around stormwater drains is leaks in the structure. Usually the leaks develop over time as a result of deterioration of the materials used to seal the joints between pipes coming in and out of the structure and the structure itself. This is usually called parging. Some other causes of leaks in the drain structures that cause sinkholes is settlement of the adjacent soils. If the ground the drain was built on sinks, it can cause the drain structure to shift. This shifting can cause joints to break and cracks to form.
