If the City vacates any right of way, or portion thereof, that user uses, user shall remove its facilities from the right of way at its own expense unless the City reserves a public utility easement, which the City shall make a reasonable effort to do. User shall be notified of proposed vacation at least 90 days before user is required to relocate or remove its facilities. If user fails to remove its facilities within 30 days, or as otherwise necessary to complete removal, after a right of way is vacated, the City may remove the facilities at user’s own expense. Upon receipt of a detailed invoice from the City, user shall reimburse the City for the costs the City incurred within 60 days, including all labor and material costs and an administrative overhead fee of 20% plus interest after 30 days.
