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 interests) 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 1/29/2021 to review the recovered items in person with the assistance of a dredge material processing facility machine and operator to sort through stockpiled items. Photographs were taken of stockpiled items at the dredge material processing facility.
Photographs of the latest material were reviewed prior to the site visit. The recovered items were spread by machine on a flat hard surface to allow for an archaeologist to clearly review them (Photographs 1 thru 5). Any item of potential interest was separated, rinsed and assessed. The reviewed material consisted of debris. The majority of the debris reviewed consisted of rocks and small pieces of wood (Photographs 1 and 2), a few larger timbers (Photograph 3), a large concrete piling (Photograph 4) and large concrete slabs (Photograph 5). No items were recommended for retention.
ITEMS SEPARATED FOR FURTHER REVIEW
The archaeologist did not encounter any items to retain for further analysis during the archaeological review on 1/29/2021.
CONCLUSIONS AND RECOMMENDATIONS
The archaeologist has concluded that no items observed during the January 29th sediment screening at the dredge material processing facility retain possible historic/archaeological significance. Per the draft Cultural Resource Monitoring Plan, the archaeologist further recommends that the non-historically/archaeologically significant debris (noted above) that has been reviewed as of 1/29/2021 may be disposed of.
