Cultural Resources Review Results #7, February 12, 2021


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 Cultural Resource Monitoring Plan. Items of potential interest (possible artifacts or objects of local interests) are placed in a separate stockpile and photographed daily 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 2/12/21 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.

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 (Photograph 1). Any item of potential interest was separated, rinsed and assessed. The reviewed material consisted of a relatively small amount of debris comprised of concrete fragments, rocks and small pieces of wood (Photograph 2) and several large concrete blocks (Photograph 3). No items were recommended for retention.

The archaeologist did not encounter any items to retain for further analysis.


The archeologist concludes that no items observed during the sediment screening retain possible historic/archaeological significance. Per the draft Cultural Resource Monitoring Plan, the archeologist further recommends that all the non-historically/archaeologically significant debris reviewed as of 2/12/2021 may be disposed of.
