This pad was initially graded as part of mass grading operations for the La Costa Commercial Development between December 1, 2012 and February 28, 2014. A summary of the results of the field observations and testing performed during the mass grading operations is referenced above. Additional remedial grading was performed on Pad 12 between September 10 and September 17, 2014. This grading consisted of excavating the pad 5 feet below existing grade. Horizontally the excavation extended at least 5 feet beyond the new planned building perimeter. In our opinion, grading was performed in general accordance with the project requirements and local grading ordinances.
