A Terra Associates, Inc. representative was on-site from 9:30 AM to 10.30 AM, as requested by the
contactor, to test previously placed utility backfill. We observed the following:
® Contractor had placed storm line along Water St. from Ocean Ave. eastward 80'; contactor had
also placed a storm crossing at intersection of Mater St. and Ocean Ave. Contractor indicated
that utility trench backfill consisted of import sand with gravel capped with 1' to 2' of import
5/8`h crushed rock. Utility trench depths ranged from 1' in the west to ---4' to the East. Backfill
had been compacted using a hoe pac. We obtained a. sample of the backfill material for
laboratory analysis. All density tests taken, as indicated below, incet compaction requirements.
