The Director shall annually issue permits granting permission to public utilities to trim and keep trimmed all trees within the streets, alleys, parks, and public places of the city in such a manner as shall keep the overhead lines of the public utilities safe and accessible. Trimming shall be done in accordance with approved practices and under the general direction of the Director of the Department. A permit, as provided for in this section, shall require reasonable prior notice to the city before any work is commenced thereunder. However, in the event of an emergency requiring immediate maintenance work on the overhead lines of the public utilities, prior notice of commencing work under a permit shall not be required. EMERGENCY as used in this section shall mean the occurrence or happening of an event which could not be foreseen by the exercise of reasonable care and foresight, which might cause damage to the overhead lines of the public utilities.
