Work crews repairing a water main break at Mount Daniel Elementary accidentally ruptured an adjacent gas main.
City of Falls Church police and Fairfax County Fire and Rescue are at the scene.
At about 1 p.m., crews cut through the gas line while restoring the broken water main, said Susan Finarelli, spokeswoman for the City of Falls Church. Students were dismissed from the school at 10:30 a.m. because of the water main break and were not at the school.
John W. Brett, spokesman for Falls Church City Public Schools, said the remaining FCCPS staff members in the school have been evacuated.
“The water main runs close to the gas main,” Finarelli said. “At this time, we are waiting for Washington Gas to arrive and repair the break. There are no other evacuations at this time.”
