Dredged material is processed according to the Level 1 Archaeological Monitoring protocol outlined in the draft Cultural Resource Monitoring Plan (revised September 2020). This protocol calls for dredged soft sediments to be placed directly into barges, floated to the processing facility, and screened over bars on a vibrating platform. Items removed during the vibratory screening process are then sorted by trained personnel as per the draft Cultural Resource Monitoring Plan. Items of potential interest (possible artifacts or objects of local interest) are placed in a separate stockpile and photographed for archaeologists to review. These items are then placed in a holding area for archaeologists to inspect. To date, the vast majority of the recovered items consisted of modern debris and timbers.
An archaeologist conducted a scheduled site visit on 4/23/21 to review items recovered as part of a probing activity at Turning Basin 1 (TB-1). The material under review consisted of a metal bollard and triangular mounting plate used on a pier or dock (Photographs 1, 2 & 3). It has been retained for further evaluation.
ITEMS SEPARATED FOR FURTHER REVIEW
The archaeologist retained one item for further analysis: a metal bollard and mounting plate.
CONCLUSIONS AND RECOMMENDATIONS
The archaeologist concludes that the item observed during the sediment screening retains possible historic/archaeological significance. Per the draft Cultural Resource Monitoring Plan, the archaeologist further recommends that all the non-historically/archaeologically significant debris at the dredge material processing facility has been reviewed by the archaeologist as of 4/23/2021 may be disposed of.
