She said the first-grade boys bathroom is "constantly plugged up. It's smelly. It's dirty."
"Our facilities can't handle the overcrowding as some of the other schools can," Mah said.
Mah also said that the school has lunch periods over two hours throughout the school day. She fears what will happen should the school become more crowded.
"Kids are having lunch from 10:45 (a.m.) to 1:30 (p.m.)," Mah said. "Next year, when you have another group of kids, that's probably going to be even earlier and even later."
Mah said teachers are having to become more creative to maintain learning standards for students.
"Our staff and administration is incredible and they bend over backwards and do everything they possibly can to make sure our kids are still doing everything they possibly need," Mah said.
However, Mah said that short term solutions such adding more portable classrooms or more teachers are becoming less of an option as the years go by.
"If we got more teachers, we wouldn't know where to put them," she said. "Getting trailers is something we definitely have to do in the short terms. It is not a long term goal."
First District Councilman Tom Quirk has a personal interest in the overcrowding at Hillcrest. His daughter is a student at the school and his son, now at Catonsville Middle School, previously attended.
"I'm very intimately familiar with the overcrowding problems there," Quirk said.
He said he is doing everything he can, as a parent and an elected official, to get Hillcrest, and Catonsville's other overcrowded elementary schools, help.
"I couldn't agree more with the parents' concerns," he said. "I'm doing everything I can to advocate for them."
