   D.   Written Authorization: Construction and repair work may be conducted at different times and at higher noise levels than otherwise permitted herein if written authorization is obtained beforehand from the city manager or his authorized representative. In granting such authorization, the city manager or his authorized representative shall consider: if construction noise in the vicinity of the proposed work site would be less objectionable at night than during the daytime because of different population levels or different neighboring activities; if obstruction and interference with traffic, particularly on streets of major importance, would be less objectionable at night than during the daytime; if the kind of work to be performed emits noises at such a low level as to not cause significant disturbance in the vicinity of the work site; if the neighborhood of the proposed work site is primarily residential in character wherein sleep could be disturbed; if great economic hardship would occur if the work were spread over a longer time; if the work will abate or prevent hazard to life or property; if the proposed early morning or night work is in the general public interest, and he shall prescribe such conditions, working times, types of construction equipment to be used and permissible noise emissions as he deems to be required in the public interest. No written authorization shall be required to perform "emergency work" as defined in section 13-15.2 of this chapter.
   E.   Revocation Of Written Authorization; Appeal: The city manager or his authorized representative may revoke any written authorization granted hereunder upon complaints based upon substantial evidence that the construction activity causes significant disturbance in the vicinity of the work site. Any person aggrieved by the granting of written authorization or the refusal to grant written authorization by the city manager or his authorized representative may appeal the decision to the city council who shall hear such appeal at the next regularly scheduled meeting of the city council.
   F.   Stop Orders: Whenever any work on a construction project is in violation of the provisions of this section, the development services director or his authorized representative, or, in the case of public works projects, the public works director or his authorized representative, may order the construction project stopped by notice in writing served on any persons responsible for the project, and any such persons shall forthwith stop work on the project until authorized by the development services director or the public works director to proceed with such work.
