The work to install a fourth geotextile container and returns on the original installation is well underway below Sankaty Bluff. A trench has been dug on the south end to provide a pool for the high-pressure pump that forces seawater into the hopper some 900′ to the north. The hopper mixes the water with sand to produce the slurry that fills the tubes.
The returns were actually required for each tier in the original project, but only one bag was put in on this north end.

The first two return bags are filled and a crewman signals the men manning the pump to shut it down.
Not just standing around, the crew walks and bounces on the geotextile containers to distribute the slurry evenly.

The first two returns. These are angled toward the Northeast, the source of the most damaging storm waves. When storms uncover the geotextile containers, it’s the second geotextile container on this end that shows first. Given that these return bags are considerably seaward of that geotextile container, it’s reasonable to anticipate that a nor’easter will uncover most of the first bag. It’s notable that these bags lack the scour aprons that were deemed necessary between each of the tiers of geotextile containers.
[Addendum] Project manager Jamie Feeley contacted us to inform us that there is one scour apron under the first below grade return bag, and provided a photo. He added that additional scour aprons are not on the current permit plans.
