Work consists of replacing two existing 13' metal arch culverts carrying an Unnamed Tributary (UNT) to Willow Creek under Cornerstone Drive with a 20'-7” Contech Aluminum Arch Culvert and wingwalls. The project also includes removing a gravel bar from the stream, restoring downstream embankments, relocating a waterline, installing a concrete utility duct bank across the stream, reprofiling the roadway to accommodate the new culvert, installing new stormwater inlets, and constructing a swale.
