In the event that materials, appliances or other equipment placed upon the streets or sidewalks in connection with work done under a building permit or public works permit or work for which a building permit or public works permit is required become a hazard to public safety or constitute a public nuisance, the Director of Public Works shall immediately, upon discovery of such hazard or public nuisance, commence to correct or cause to be corrected the condition or conditions causing the hazard or public nuisance, or cause the permittee or other responsible party to correct the condition causing the hazard or public nuisance if able to correct immediately and to the satisfaction of the Director of Public Works. Such correction may be undertaken by the Director of Public Works, without notice, if they reasonably consider it to be in the public interest so to do. The cost of such correction shall be paid by the permittee or other responsible party upon demand of the director of public works, and if not paid upon demand, shall be deducted from the moneys which have been deposited, or paid by the surety company on its bond, if a surety bond has been filed in lieu of the required deposit. The costs for which payment shall be made shall include labor, equipment, overhead, supervision, engineering, inspection, and the cost of any public work delayed by reason of the existence of such hazard or public nuisance.
