Section 600:10. Backfill. Backfilling of all street openings shall be thoroughly compacted. Compaction of materials placed within the pipe bedding and encasement zones shall be accomplished with portable or hand equipment methods, so as to achieve thorough consolidation under and around the pipe and avoid damage to the pipe. Above the cover zone material, the use of heavy roller type compaction equipment shall be limited to safe pipe loading.

The maximum loose thickness of each backfill layer shall be eight (8) inches, except that twelve (12) inches will be permitted for granular materials placed above an elevation one (1) foot above the top of pipe, and with the provision that, by authority of the Engineer in consideration of the demonstrated capability of special type vibratory compactors, these maximums may be increased at his discretion.

All excess material resulting from the excavation, if any, shall be removed by the party obtaining the opening permit. The Engineer shall be notified immediately in writing upon completion of the backfilling and the City of Owatonna shall replace the street surfacing. The applicant for the street opening permit shall be responsible to the City of Owatonna for any subsequent settling of streets for openings which have not been adequately backfilled and compacted, and any and all expenses incurred by the City of Owatonna as a result thereof to remedy such settling shall be charged against such applicant in the following manner: The Engineer shall maintain an accurate cost analysis of the cost to the City for backfilling ditches settlings, which analysis shall show the location of each ditch and the applicant of the opening permit therefor.
