Excavated material shall be deposited so as to interfere as little as possible with the execution of the whole work or its several parts, and in such a manner that for each purpose the most suitable material may be placed in its final position, but not in a manner to interfere with the satisfactory carrying out of the work. Such material as cannot be placed in its final position in fills and embankments shall be removed to a temporary soil bank, from which it shall later be taken and placed in embankments or fills. Unsuitable and surplus excavated material not incorporated in the improvement shall be disposed of by the contractor at his or her own expense. (Ord. 352. Passed 10-22-62.)
