WEST HOLLYWOOD, LOS ANGELES (KABC) -- Some parents at a local charter school are concerned that a cellphone tower may be going up near the campus despite limits on where those towers can be installed.Concerned parents of Larchmont Charter School contacted Eyewitness New using #abc7eyewitness. They said they recently found out about the plan to install a cell tower inside a bell tower at St. Ambrose Church, which is directly next to the school.Parents said radiation from the cell tower will have harmful effects on their children."I have a Ph. D and a Masters in medical sciences from Harvard Medical School. I know there are many, many studies about the increased chances of cancer and the increased risks, and I don't know why we would take any risks with our children," Valerie Weiss said.The Los Angeles Unified School District has a ban on cell towers near schools, which gave many parents hope until they contacted the district for help.Daisy Gardner said there was nothing the LAUSD could do because it is a charter school.In a statement, the Archdiocese of Los Angeles said, "The proposal is in preliminary stages and has yet to be finalized or approved. The public hearing process will start soon and provide a forum for community members to share their opinion."A public hearing is scheduled with the city of West Hollywood on Dec. 3 at 6 p.m. at the West Hollywood Library, 625 N. San Vincente Blvd.
