The permit holder will be responsible for the safeguarding of all excavations and obstructions in the street, sidewalk, curb, gutter, or area between the sidewalk and curb. He shall place around the same a substantial rail or guard to prevent accidents, and conspicuously place and maintain one or more red or amber lights. The permit holder shall take appropriate measures to assume that during the performance of the excavation work, traffic conditions as near normal as possible shall be maintained at all times so as to minimize inconvenience to the occupants of the adjoining property and to the general public.
(a) When traffic conditions permit, the Mayor may, by written approval, permit the closing of streets and alleys to all traffic for a period of time prescribed by him, if in the Mayor’s opinion it is either reasonably necessary for the protection of public safety or it will substantially decrease the time or cost of performance without unreasonable inconvenience to the general public. The written approval may require that the permit holder give notification to various public agencies and to the general public. In such cases, such written approval shall not be valid until such notice is given.
(b) Warning signs shall be placed far enough in advance of the construction operation to alert traffic within a public street and cones or other approved devices shall be placed to channel traffic, in accordance with the instructions of the Mayor.
