Page 5 <br /> <br /> <br />Slope Stability <br /> <br />The site is a flat area; therefore, slope instability is not a concern for the proposed <br />development. <br /> <br />CONCLUSIONS AND RECOMMENDATIONS <br /> <br />General Conclusions <br /> <br />Construction of the proposed structure at the subject site is considered geotechnically <br />feasible, provided the recommendations outlined in this report are implemented. <br /> <br />Note: The conclusions and recommendations of this report are based on information as <br />interpreted from our limited subsurface investigation. It is not anticipated but they should <br />be revised accordingly if geotechnical conditions to be exposed during site preparation/ <br />grading and construction significantly differ from our findings and interpretations. <br /> <br />In general, a conventional shallow foundation can be used for support of the proposed <br />structure. <br /> <br />The following recommendations are considered minimum and may be superseded by <br />more restrictive requirements of the architect, civil/structural engineer, building codes, or <br />governing agencies. <br /> <br />Geotechnical Impact on Neighboring Properties <br /> <br />Adverse geotechnical impact of the proposed development on the neighboring properties <br />is not anticipated, provided the recommendations outlined in this report are properly <br />implemented. <br /> <br />Site Preparation/Grading <br /> <br />To create a relatively uniform new engineered compacted fill layer for a proposed new <br />structural slab-on-grade area, over-excavation and re-compaction of 3 ft. deep (measured <br />from the existing ground surface) of the existing on-site soils should be performed. The <br />lateral limits of the over-excavation should be minimum equal to depth of removal (3 ft. <br />in this case) beyond the outside perimeter of the proposed new structure. For the <br />proposed new exterior concrete slabs including new driveway, if any, the over-excavation <br />and re-compaction should be minimum 1 ft deep and 1 ft. outside of the new slab areas. <br />Deeper remedial removal is not anticipated; however, this will be determined in the field <br />by the project geotechnical engineer, based on the actual conditions to be exposed at the <br />time of the site grading/preparation. The new fill/backfill materials should be free of <br />organic matter and oversized materials, 4 inches or greater in diameter, placed in near- <br />horizontal loose lifts not to exceed eight inches in thickness, and moisture conditioned to <br />slightly over optimum moisture content prior to compaction.
