LANCASTER — Months of explosive blasting are expected to begin at the site of Center Hill Dam next week as the U.S. Army Corps of Engineers prepares to begin construction work at the aging dam in Lancaster.
"The blasting will be to excavate a platform for construction, about 40 feet wide and will look similar to a road cut through a hill," [Corps Project Manager Linda Adcock] said. "Just the nature of how we grout, and moving equipment back and forth on the current slopes, which are as much as 40 percent and greater, is just really difficult. So for these reasons, for safety, quality, the accuracy and the consistency of the drill holes are much better done from a platform, they proposed this road cut type of a platform."
