A large amount of debris from construction going on at the former CSR Arts building was left piled on the on north side sidewalk of Chestnut Street. It takes up the entirety of the sidewalk and is a hazard to any pedestrians. No permits have been issued for blocking the sidewalk and no barricades were erected to indicate the hazard and is poorly lit. Someone is going to get hurt. This is just the latest hazard caused by the construction on this property. They have been parking large trucks on the sidewalk--prevents safe passage by pedestrians and potentially causing structural damage to the sidewalks.
