In Kokomo, Indiana, State Highway 931 faced an unusual infrastructure challenge as erosion threatened the creek bank at the base of a high-tension power line tower situated in a retention pond. imi Aggregates provided a solution to prevent continued erosion.
In Kokomo, State Highway 931 passes over Kokomo Creek at the same point where two banks of high-tension power lines cross. The two lines are supported by a tower in the middle of a retention pond that overlooks the creek. In time, the moving water in the creek began to erode the bank. The erosion was threatening to wear away the bank that held the retention pond in place as well as potentially compromising the base of the tower.
imi Aggregates was asked to develop an erosion control solution. It was suggested that the creek’s edge be lined with concrete barriers and the bank be covered with revetment rip rap. imi supplied 6’x2’x2′ concrete blocks that were placed along the creek. imi also supplied 650 tons of stone rip rap on the bank and surrounding the retention pond. The stone helped keep the soil in place when the creek flooded and also created a barrier to keep large objects from floating into the retention pond.
