Paddy Creek Dam Seismic Upgrade

Morganton, North Carolina
Client: Devine Tarbell & Associates, Inc.
Owner: Duke Energy

The Paddy Creek Dam is one of three dams that make up Lake James in North Carolina, and was constructed utilizing the semi-hydraulic fill method. It was determined that the dam was subject to failure during an earthquake. The FERC-mandated rehabilitation project was designed by Devine Tarbell & Associates, Inc., and included a 3,000 ft dewatering system and 1.1 million cubic yards of excavation and embankment, 200,000 tons of aggregates, and 120 acres of reforestation.

Fall Line's senior-level engineering technicians performed construction related inspection and testing of the fill material and filter blanket materials. Laboratory tests were performed to verify that materials utilized met the project specifications. Field inspectors were also on site to inspect the placement of filter blanket materials and subsequent placement of fill materials, and also to perform density testing of compacted soils.
