C. Penney Company, Inc. <br />p. 0. Box 997 <br />New York, New York 10001 (Our Job No. A-71009) <br />Attention: Mr. Robert Keller, A.I.A. <br />Gentlemen: <br />Supplementary Grading and Paving Recommendations <br />Proposed Department Store <br />Sunflower Avenue and Bristol Street <br />Santa Ana, Cali fornia <br />This letter confi rms our discussions with Maxwell Starkman & Associ - <br />ates and with other interested parties concerning grading and paving at the <br />subject site. We previously investigated.the soil conditions beneath the <br />site and submitted our report of foundation investigation on February 8, 1971. <br />A prior supplementary letter was submitted on July 8, 1971. <br />Recommendations· for grading and paving design were presented in our <br />report, and these recommendations are still applicable.It has now been de- <br />termined that the floor will*be established at Elevdtion 34, requiring the <br />placing of abbut 2-& feet of fill beneath the building area. Imported fill <br />material will be requi red in grading the site. We understand the imported <br />fill material will be obtained from the Fashion Island Shopping Center area <br />in Newport Beach. The imported material will, be relatively non-expansive, <br />predominantly granular silty sand material. The on-site soils are expansive <br />clay materials. <br />As stated above, the gradi'ng recommendations of our report are still <br />applicable. The existing soils within the building area and beneath adjacent <br />walks and slabs should be excavated to a depth of at least two feet below <br />the existing grade to remove soft, wet material, and the building area brought <br />to grade by placing properly compacted fill. At least the upper two feet of <br />required fill should consist of relatively non-expansive, predominantly granu- <br />lar soils. <br />RICEN:-'id <br />.DEC 1 1971 <br />L. LeROY CRANDALL. C.
