fines passing #200 sieve. This minimizes long term soil movement due to soil creep and freeze- thaw action. Backfill must be capped with compacted cohesive backfill as shown in Appendix C to - minimize surface water infiltration into backfill. Backfill must meet recommendations in the EXCAVATION AND EARTHWORK section of this report. The area between this triangular prism and sloping excavated surface can be backfilled with either cohesive or granular soil meeting structural fill recommendations in this report. Granular backfill must be free-draining and well- drained permanently into perimeter wall drain lines, installed according to recommendations in the WATERPROOFING section of this report. GENERAL If any changes in the nature, design or locations of structures are planned, then the conclusions and recommendations in this report are not valid. However; if we are provided an opportunity to review these changes, the conclusions and recommendations in this report can be modified and verified in-writing. Analyses, recommendations and conclusions in this report are based, in part, on subsurface conditions encountered in the exploratory soil borings. The nature and extent of variation of subsurface conditions across the site may not become apparent until the construction _._ stage of the project. If variation in subsurface conditions becomes apparent, our analyses, recommendations and conclusions in this report must be reviewed and reevaluated. - We recommend that the Geotechnical Engineer be provided the opportunity to generally review designs and specifications for the construction project. By making this review, the recommendations in this report can be properly interpreted and implemented with regard to the project designs and specifications. Finally, we recommend retaining the Geotechnical Engineer to provide continuous engineering service during the construction stage of the project, with emphasis on excavation, earthwork and foundation construction. This construction stage on-site presence by the Engineer will be to observe compliance with design concepts, specifications and recommendations in this report. This presence also provides an opportunity to modify these - design concepts, specifications and recommendations in the event subsurface conditions differ from the anticipated conditions. _ Respectfully Submitted, JIED TEST DRILLING COMPANY Reviewer es M.
