Tisbury Seeks USACE Permit to Dredge in Vineyard Sound

The Town of Tisbury Harbormaster is seeking a permit from USACE’s New England District to dredge in Vineyard Sound and Lake Tashmoo Inlet Channel and use the sand for beach nourishment.

The town is proposing maintenance dredging of approximately 25,000 cubic yards of mostly sandy material over 10 years from approximately 5.1 acres (221,156 square feet) of subtidal habitat in the Lake Tashmoo Channel to a depth of -7 feet mean low water by hydraulic and mechanical means.

Approximately 5,000 cubic yards will be removed every other year, USACE said in its release.

The dredged material is to be placed as beach nourishment above and below the high tide line of Vineyard Sound on a 4.74 acre (206,600 square feet) area of town beach located adjacent to the Channel, with the exception of sediment removed from station 26+50 to 30+00. This sediment, approximately 3,210 cubic yards of silty sand, is not suitable for beach nourishment and will be transported to an upland location.

The location will be approved by the Corps of Engineers prior to disposal.

In addition, the town is proposing to dredge approximately 500 cubic yards of mostly sandy material from approximately 5,600 square feet of subtidal habitat at the Town Landing adjacent to Lake Street in Tisbury to a depth of -6 feet mean low water by mechanical means.

Approximately 100 cubic yards of material will be removed every other year for 10 years and used as beach nourishment at the Vineyard Sound location.

According to the official announcement, public comments on this dredging scheme should be forwarded no later than August 17, 2017 to the U.S. Army Corps of Engineers, New England District.
