The Project goal is to restore the existing ponds at the Bailey Arboretum to their historic condition. A considerable amount of fine grained organic sediments have accumulated over time in the 2 ponds. This sediment accumulation has reduced the pond's ability to: act as stormwater buffers; provide suitable habitat for aquatic wildlife; and provide high aesthetic quality integral to the Arboretum. A maximum of 5,000 cubic yards will be removed from the ponds. The removal of sediments shall be conducted via hydraulic dredging and dewatering on site using geotubes (to be located adjacent to the ponds in the Bailey Arboretum parking area) and disposal of the dredged materials offsite at an approved disposal facility. Dewatering from the geotubes shall be directed back into the ponds. The existing pond weirs can be utilized to provide flow control in the ponds and to allow suspended solids to settle in the ponds and to not discharge downstream and to the receiving waters.
