A sinkhole recently appeared at the end of Elm Drive in St. Albans, opposite Oakwood Drive, in May. As is typical with sinkholes, it appeared suddenly without warning. The hole was reported to be approximately 2 meters in diameter and 2 meters deep. Thames Water was notified of the damage, but the exact cause was never confirmed. However, it is assumed that the hole was created by a leaking water main, which caused the chalk bedrock to dissolve and led to the liquefaction of the clay. It took two weeks for Thames Water to address the situation, repair the damage, and resurface the road.
