Except as otherwise permitted in agreements between the city and a public utility operating within the city limits, no person shall excavate, oil, grade, surface, repair, construct, reconstruct or do any work upon a public sidewalk, street, alley, curbing, or within any other portion of public right-of-way, or within an easement granted to the City, unless a permit for the work has been issued by the manager. The person applying for the permit shall pay the appropriate permit fee provided for in the most recent schedule approved by resolution of the City Council. Fees shall not exceed the average or actual cost of providing the service covered by the permit. This fee schedule shall be amended periodically by resolution of the City Council and kept on file in the Engineering Division and the City Recorder’s office.
