Lateral travel distance to an exit laddbr or steps shall not be greater than 25 feet in trenches 4 feet or deeper. C. Perform excavation as indicated for specified depths. During excavation, stockpile materials suitable for bacdilling in orderly manner far enough from bank of trench to avoid overloading, slides, or cave -Ins. D. Remove excavated materials rat required or not suitable for bacldill or embankments and waste as specified. Any structures discovered during excavation(s) shall be disposed of as specified. E. Prevent surface water from flowing into trenches or other excavations by temporary grading or other methods, as required.
