FOUNDATIONS This section is not applicable to this construction project. 3. EMBANKMENTS The embankment construction included returning the eroded berm to its original geometry. Native soil was excavated with a mini excavator upstream of the project location. The Responsible Engineer was onsite during all construction activities and ensured that backfill and compaction was performed per the FERC-authorized Work Plan. The adhered-to specifications are shown below: • Prior to backfill placement the subgrade was free of debris and loose soils. Backfill was benched to help create good bonding and reduce the likelihood of a slip surface. • The bottom of the excavation was scarified, moisture conditioned and recompacted prior to backfill placement. • The backfill was free of roots, rocks, trash, organics, or other deleterious materials. • Backfill was placed in lifts no greater than 6-inch of uncompacted thickness. The material was moisture conditioned and compacted using jumping jack style compactor with a minimum of two passes. • Each lift of backfill was compacted until firm and unyielding and approved by the onsite engineer prior to placing subsequent lifts. 4.
