This Powerline Interim Dam project was constructed to help protect an existing earthen dam structure and the citizens living downstream of the structure. The large earthmoving project included 1.3 million CY of excavation, material processing, and placement. The detailed specifications included specific parameters for embankment fill as well as a central sand filter that was constructed in the center of the earthen dam structure on a 1.5:1 slope. The project required working in conjunction with multiple agencies to realize the goals of meeting the project schedule, budget, and strict specifications to ensure public safety.
