ALTAMONTE SPRINGS, Fla. — Crews continue to try to determine the cause of a sinkhole that opened beneath an Altamonte Springs condominium building Tuesday, forcing 13 residents to evacuate, the Altamonte Springs Police Department said Monday.
The hole, which grew to 20 feet wide and 20 feet deep, opened at about 6 p.m. Tuesday at the Royal Arms Condominiums near East Altamonte and Palm Springs drives.
Police had originally said Friday that the sinkhole was caused by testing done by a geology firm, but then they said Monday that the official cause is unknown.
"Any cause determination will be made by the professional engineers conducting the investigation," said Michelle Sosa, a police spokeswoman.
She said the hole was filled and that residents were allowed to return to their homes Monday after crews conducted structural evaluations.
