P An evaluation of the site was performed by our firm in August 1987. Results of the investigation were presented in our Soil and Foundation Investigation Report, Project No. 87-l 68, dated August 13, 1987 . 2.1 2.2 Site Grading Site grading consisted of the excavation and recompaction of the upper 1 to 3 feet of the on-site soil. Gradina Period Grading operations commenced on May, 1988. Our final inspection of the utility .backfill was on March 27, 1989. 3.0 GRADING ORSFRVATION 3.1 Jurisdiction Grading activities for the development were under jurisdiction of the City of Carlsbad.

Field Testina Procedures Test Methods - Field density tests were performed with a 6-inch sand cone in accordance with the procedures outlined in A.S.T.M. Test Method D1556, and the Nuclear Test (A.S.T.M. D2922 and D3017). Number of Tests - The results of the 166 field density tests performed during this phase of grading are presented in the “Summary of Field Density Tests.” Field testing was used to determine the degree of compaction as fill materials were being compacted. ) ocation of Field Tests - The approximate location of each field density test is identified on the “Density Test Location Plan,“, Figure No. 1.

Utility trenches observed consisted of sewer, water, storm drains, electric, and gas. Footina Observation The building pad footing excavations were observed by a representative of our firm. The exposed footing trenches were found to be satisfactory and suitable for the placement of concrete. . mrsh Grading On-site drainage is provided by surface gradients sloping away from the structures to suitable discharge facilities The opportunity to be of service is sincerely appreciated.
