As a condition of a Surface-Mounted Facility Site Permit, each Permittee agrees on behalf of itself and any agents, successors, or assigns to be wholly responsible for the construction, installation, and maintenance of any permitted Surface-Mounted Facility and the installation of any required street trees. Each Permittee and its agents are jointly and severally liable for all consequences of such construction, installation, and maintenance of a permitted Surface-Mounted Facility and the installation of any required street trees. The issuance of any Permit, inspection, repair suggestion, approval, or acquiescence of any Person affiliated with the City shall not excuse any Permittee or its agents from such responsibility or liability.
