Backfilling shall be completed by placing the backfill material well up over the top of the trench. For dry backfilling, the material shall be compacted with a roller of an approved type or with the rear of a truck carrying at least five tons until the surface is unyielding. Care shall be taken that material being compacted has proper moisture content for maximum compactibility. The surface shall then be graded as required. (Ord. 530 § 2, 2018)
