A mountain of garbage has been growing outside a Morrisania school all summer long. With classes back in session, school staff says its time the Department of Sanitation does something about it.

Students at Mott Hall Charter School returned to school with an unwelcome sight, and the school's principal has already had enough of it.

"Yesterday we had the entire school came back and there was the issue of parents not being able to stand ... kids being dropped off can't come near because the garbage is everywhere," says principal Connie Lobdell.

The school was a summer school site and offered meals to the community. Lobdell says the mountains of trash are filled with food and milk and have piled up due to inconsistent trash pickups.

Lobdell says that this isn't a new problem -- it has been ongoing for at least a year.

"The neighbors come out, they ask for help, the parents complain ... it's just not something you'd see anywhere else," says Lobdell.

The campus is shared with P.S. 63, which returns to school Thursday.

News 12 reached out to the Department of Sanitation, which says it would look into the situation.
