However, previous <br />sections have indicated that the on-site soil consists of expansive soil and that expansive clay should <br />not be placed within the upper 3 feet of building pads. Consideration should be given to clarifying what <br />on-site soil and rock is acceptable as fill material or clarifying where it can be used. In addition, this <br />section indicated that fill material should have a plasticity index of less than 12. Clarification should be <br />given to whether this refers to on-site soil or imported fill. <br /> <br />ENGEO Response to Comment 14 <br />We will clarify this in the Reference 2 update. Note that the building pads will be cut pads, so limited <br />if any fill would be placed in the building pads. The clarification will be as per Response to <br />Comment 13. <br /> <br />Comment 15 Geotechnical Report, Section 6.6.2.2 (Structural Areas) Note 2: <br />It appears that the second sentence in this note is incomplete. Please provide clarification if <br />appropriate. <br /> <br />ENGEO Response to Comment 15 <br />We will address this in the Reference 2 update. <br /> <br />Comment 16 Geotechnical Report, Section 6.6.2.2 (Structural Areas): <br />Consideration should be given to eliminating the option to use native clay soils for pipe bedding and <br />backfill where utility trenches cross perimeter building foundations. Consideration should be given to <br />only recommending sand cement slurry for this purpose because it is very difficult to properly compact <br />clayey soils under the pipe haunches. <br /> <br />ENGEO Response to Comment 16 <br />We have success with this recommendation; we will leave this portion of the report as is.
