(A) The permittee shall maintain safe crossings for two lanes of vehicle traffic at all street intersections where possible, and safe crossings for pedestrians at intervals of not more than 300 feet. The contractor is also restricted to open-cutting half the roadway surface at any one time.
(B) The permittee shall take appropriate measures to assure that during the performance of the excavation work, traffic conditions as nearly 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. When traffic conditions permit, the Mayor and/or the Public Works Director may, by written approval, permit the closing of streets and alleys to all traffic for a period of time prescribed by him if, in his opinion, it is necessary. Such written approval may require that the permittee 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.
