In the event the grantee’s performance of any of the terms and conditions or obligations required by this chapter is prevented by a cause or event not within the grantee’s control, such inability to perform shall be deemed excused and no penalties or sanctions shall be imposed as a result thereof; provided, however, that shall not relieve a grantee from its general obligations to provide pro rata credits or rebates for interruptions in service. For the purpose of this section, causes or events not within the control of the grantee shall include without limitation acts of God, strikes, sabotage, riots or civil disturbances, restraints imposed by order of a governmental agency or court, explosions, acts of public enemies, and natural disasters such as floods, earthquakes, landslides, and fires, but shall not include financial inability of the grantee to perform or failure of the grantee to obtain any necessary permits or licenses from other governmental agencies or the right to use the facilities of any public utility where such failure is due solely to the acts or omissions of the grantee, or the failure of the grantee to secure supplies, services or equipment necessary for the installation, operation, maintenance or repair of the cable communications system where the grantee has failed to exercise reasonable diligence to secure such supplies, services or equipment. (Ord. 5531 § 2, 2004.)
