4g. Comments:
Dam elevation is being raised to a consistent 169.5 and dam face will be constructed to a 3:1 slope. Footprint expansion will be
on the downstream side where possible, but will be on the upstream side along the southern end of the dam where existing
buildings and Terry Sanford Drive prohibit any expansion. The lake is currently drained in preparation for this work.
