The pad of compacted soil must extend at <br />least 3 feet beyond the footprint of the proposed structures. <br /> <br />Any and all surficial soft dry soil must be removed and replaced in order to minimize the <br />potential differential settlement. <br /> <br />It is recommended that all surface which is loose that will support patio, sidewalk slabs, <br />or asphalt concrete paving, and all surface which will receive fill or backfill, be scarified <br />to a depth of 8 inches, dried to near Optimum Moisture Content and re-compacted to a <br />minimum of 90%. <br /> <br />Where fill or backfill is required, it should be placed in a maximum of 6-inch loose layers <br />and each layer compacted at near Optimum Moisture Content to at least 90% <br />compaction. Clean on-site soils may be utilized as fill material. <br /> <br />Imported fill soil should be predominantly granular, non-expansive and capable of <br />developing the bearing strength required for the project. <br /> <br />All import soil must be approved by this office prior to bringing to the site. <br /> <br />All retaining walls and utility trenches backfilled should be tested at a maximum of 2 feet <br />in vertical height. Compaction Standard: A.S.T.M. D-1557. <br /> <br />Water-soluble sulphate content will be determined at the conclusion of the grading if <br />requested by the client or required by the approving agencies. <br /> <br />As per the City’s requirement the final grading and foundation plan should be submitted <br />to this office prior to starting the grading/construction. <br /> <br />A pre-grade meeting is required in accordance with the City of Santa Ana grading <br />code. <br /> <br />Geo-Etka, Inc. should be retained to observe all grading operations and the required <br />testing for implementing the recommendations of this report. <br /> <br />If a change in the consultants occur Geo-Etka, Inc., must be notified in writing and all <br />liability will shift to the client and his consultants of record. <br /> <br />2010 & 2012 N Bush Ave, <br />#100 and #1012/21/2025
