Dear Mr. Anderson: Representatives from EnGEN Corporation have performed observations and conducted in-place density tests during the grading operations of the building pad as shown on the above-referenced plans for the subject site. The grading antl compaction operations were performed in accordance with the recommentlations presented in the Referance No. 1 Report and meet the minimum stantlards and requirements of the City of Temecula Grading Ordinance. Materials placed within the building pad on the subject site have been compacted to a minimum of 90 percent relative compaction. A formal report of all rough grading observations and testing will be submitted after completion of the Rough Grading Report for the subject site. The final grading report will include all in-place tlensity test results and their locations, as well as laboratory test results.

Robert Bein, William Frost & Associates, July 12, 1996, Grading Plan, Lot 1, Parcel Map 28317, City of Temecula, County of Riverside, California, Sheet 1 of 1. Dear Mr. Oftedai: In accordance with your request, EnGEN Corporation has conducted R-Value testing of the subgrade soils proposed for pavement parking lot and access road at the referenced site. The recommended pavement design is based on R-Value test results from a sample of subgrade material obtained by a representative of EnGEN Corporation on May 26, 1997, from a location designated during field observations and review of the referenced grading plan in proposed pavement areas. - Los Mgeles Omlce Orange County Ottke Post ORice Box 1 a9J 2615 Oronge Avenue Lancasie�, CA 93534 Santa Arta.

The R-Value test was performed by G.E.E. in generai accordance with California Test Method 301 procedures. The test results are attached. The following pavement recommendation is based on the sub-grade soii having a minimum R-Value of 52. Tra�c Indexes (TI) of 4.5 and 5.0 were assumed for the pavement design in the parking lot and access road areas, considered to be representative of light to moderate automobile traffic. The recommended pavement sections are as follows: Area Traffic Index Recommended Section Parking Lot 4.5 3.0" Asphaff Concrefe over * 4.0" Class 2 Aggregate Base over properly prepared Subgrade. Access Road 5.0 3.0" Asphalt Concrete over * 4.0" Class 2 Aggregate Base over properly prepared Subgrade. * City of Temecula minimum standard. Asphalt concrete pavement materials should be as specified in Sections 39-2.01 and 39- 2.02 of the current Caltrans Standard Specifications or a suitable equivalent. Aggregate base should conform to 3/4-inch Class 2 material as specified in Section 26-1.02B of the current Caltrans Standard Specifications or a suitable equivalent. To properly prepare the subgrade, the soil should be recompacted to a minimum 90 percent relative compaction, to a minimum depth of 12-inches below finish subgrade elevation. The aggregate base material should be compacted to at least 95 percent relative compaction. Maximum dry density and optimum moisture content for subgrade and aggregate base materials should be determined according to ASTM D1557-91 procedures. If pavement subgrade soils are prepared and aggregate base material is not placed immediately, or the aggregate base material is placed and the area is not paved immediately, additional observations and testing will be required prior to placing aggregate base material or asphaltic concrete to locate areas that may have been damaged by construction traffic, EnGEN Corporation - � � Doctor's Medical Park Project No. T1077-C June 1997 Page 3 construction activities, and/or seasonal wetting and drying.
