It shall be unlawful for any person or firm to engage in the business or occupation of pruning, treating or removing street or park trees within the city without first applying for and procuring a city business license. The business license fee shall be paid in advance; provided, however, that no license shall be required of any public service company including electric utilities and their agents and contractors or city employees doing such work in the pursuit of their public service endeavors. Before any business license shall be issued, each applicant shall first file evidence of possession of liability insurance in the minimum amounts of one million dollars ($1,000,000.00) for bodily injury and one hundred thousand dollars ($100,000.00) property damage indemnifying the city or any person injured or damaged resulting from the pursuit of such endeavors as herein described.
