LABORATORY TESTING PROGRAMS <br />Samples of the in -situ soils recovered from the borings were used for our visual <br />material and further laboratory testing to obtain data for foundation design and <br />recommendations. <br />The laboratory testing consisted of performing classification, strength (shear), di <br />density and moisture content; and determining the moisture -density relationship <br />CITY OF SANTA ANA <br />PlannirA� Bpil� g Agency <br />�antaAna CA 92170; <br />Approved <br />FOR PERMIT ISSUANCE <br />ssification of the <br />preparation <br />Master ID: <br />Date: <br />mining in -situ dry <br />Descriptions of test procedures are included in the Appendix of this report. <br />The results of the testing are the basis for the conclusions and recommendations in the report. <br />SUMMARY OF SOIL AND DESIGN PROPERTIES <br />The following subsections and sections will present our detailed conclusions and recommendations for <br />the development of the site. <br />Basic Soil Properties <br />Maximum Density <br />The Maximum Density for the olive brown silty sand per (ASTM D1557) <br />Boring #1 117.8 pcf @ 13.2% MC <br />Boring #2 118.6 pcf @ 13.1 % MC <br />For compaction control during excavation and recompaction of the on -site soils use: <br />Boring #1 116.02 pcf (q�, Optimum moisture <br />Boring #2 106.74 pcf @ Optimum moisture <br />Direct Shear <br />The Shear values for the olive brown silty sand per (ASTM D3080) <br />Bearing Value <br />Peak <br />Boring #1 330 <br />Boring #2 250 <br />For design purposes 2700 psf <br />Ultimate <br />Angle <br />140 <br />280 <br />140 <br />270 <br />2 <br />
