“I’m looking out for the safety and well-being of our employees on that rough terrain to clean it up as best as we can,” Norwin School District’s Director of Facilities and Property Services P.J. Petrarco said in a release. “Clearing the hillside is also beneficial for the safety of our students and staff.”

The district said the goats are fenced in — allowing them to focus on the assigned area — and being cared for during the stay.
