Campus Policy 3018 restricts noise levels, the installation of temporary structures, and the deposit of unattended literature. It also imposes many common-sense safety measures, for example, any activity many not unreasonably disrupt traffic, either vehicular or pedestrian, or interfere with the ingress or egress to or from a building. Additionally, scheduled events in outdoor spaces may require approvals to ensure sanitation and safety and the orderly operation of university business.
