The upper one foot of existing subgrade was then scarified, moisture conditioned, and compacted. Areas of soft, pumping soils were mitigated by removing additional soils that were soft and wet to exposed firm sub-grade. Soils were then moisture conditioned, placed, and compacted to a minimum of 90 percent relative compaction. Utilities for the Event Garden included area drains and storm drains. For utility construction trenches were excavated, utilities were installed, and the excavations were backfilled with on-site soils. Fill Materials Fill soils used during consh·uction consisted of on-site and impmted silty sand. Representative soil samples were collected and laboratory testing consisting of maximum dry density and optimum moi~ture content was performed in general accordance with the test procedures outlined in ASTM D1557. The results of the laboratory testing are presented on Table 1. Field Density/Moisture Testing In-place moisture and density tests were performed in general accordance with ASTM D 6938 for soils. The results of these tests are tabulated in Tables 2.1 and 2.2. Field density testing was performed at random locations and elevations. The approximate locations of the field density test are shown on Test Location Plan (Figure 1 ). Foundation Excavations Foundation excavations were observed for the site walls and retaining walls on February 16, March 1, and March 2, 2017. The walls were designed and constructed using the San Diego Regional Standard Drawings. The conditions exposed in the foundation excavations are consistent with the anticipated soil conditions outlined in the Regional Standard Drawings and are considered suitable for the support of the proposed structures.
