Footing excavations should be cleaned of loose debris and thoroughly moistened just prior to placing the concrete. 2.

We note that clayey soils may take an extended period of time and the contractor should schedule accordingly. 3. In the event of a site change subsequent to our footing observation and prior to concrete placement (i.e. heavy rain, a construction/placement delay, etc.), we should be contacted to perform additional site observations, as necessary. tion test results, including depth of fill, relative compaction, bearing values, and soil expansion index test results are in the As-Graded Geotechnical Report provided at the completion of grading. ,~}11/>s For Date ' FOOTING OBSERVATION SUMMARY Received by: Print: White -File Copy Yellow -Client Copy Pink -Field Copy LGC VALLEY, INC.

Project No. 15-6428, dated August 3, 2015 Delta I Revision dated October 8, 2015 In accordance with your request, LGC Valley, Inc., (LGC) has prepared this letter to provide an update of the presaturation recommendations for the single-family residential foundations of The Vistas Development (i.e. Lots I through 23 of Planning Area PA-13 and Lots 158 through 244 of Planning Area PA-6) part of the Robertson Ranch project located in the City of Carlsbad, California. The updated presaturation criteria presented herein are based on expansion potential testing of representative finish grade soils, geotechnical analysis, and our review of the referenced letter and foundation plans. Addendum and/or final geotechnical recommendations, if applicable, will be presented in our as-graded report that will be prepared upon completion of the rough and fine grading operations. Single-Family Residential Foundations Presaturation Recommendations The slab subgrade soils underlying the single-family residential foundations should be presoaked in accordance with the recommendations presented in Table 1 prior to the placement of the sand, moisture barrier, and concrete slab. The expansion potentials of the lots are also presented on the attached Figure 1. The subgrade soil moisture content should be checked by a representative of LGC prior to slab construction. 2420 Grand Avenue, Suite F2 •Vista• CA 92081 • (760) 599-7000 • Fax (760) 599-7007 Presoaking or moisture conditioning may be achieved in a number of ways, but based on our professional experience, we have found that minimizing the moisture loss of pads that have been completed (by periodic wetting to keep the upper portion of the pad from drying out) and/or berming the lot and flooding for a short period of time (a few days to a week) are some of the more efficient ways to meet the presoaking requirements. If flooding is performed, a couple of days to let the upper portion of the pad dry out and form a crust so equipment can be utilized should be anticipated.
