Summary of Status Updates Presented by EPA at the September General Meeting of the Gowanus Canal Community Advisory Group

RH-034 (CSO retention tank at the head of the canal along Nevins Street)

  • Micropile installation has been completed on the northern half of the tank. Concrete pouring for the base of the tank has begun in this area.
  • Micropile installation is ongoing for the southern half of the tank and is expected to be completed by the end of November, followed by concrete pouring for the base of the tank in this area. 
  • Waterproofing of the tank base and sidewalls is ongoing.
  • A new, larger crane was mobilized to the site last week. It will be used to lower forms into the tank footprint for concrete pouring of the side walls.
  • Construction of the tank (i.e., below-ground construction) is expected to be fully complete by September 2026.
  • New York City Department of Environmental Protection (NYC DEP) staff and their contractors are currently working one shift per day, approximately 8 to 10 hours per shift depending on the length of concrete pouring on any given day.

OH-007 (CSO retention tank at the Owl’s Head Peninsula near 2nd Avenue and 6th Street)

  • Construction of the new composting facility has been completed.
  • Construction of the new salt shed is ongoing, including painting and installation of the wall and roof panels. This is expected to be complete by the end of October. 
  • Perimeter wall construction is ongoing. As of September 30, 132 of 138 perimeter wall panels have been completed. This work is expected to be completed in the next two weeks. 
  • The next phase of work will consist of jet grouting of the panels down to the bedrock layer beneath the site. This is expected to be completed in late winter followed by soil excavation of the tank itself. 
  • NYC DEP staff and their contractors are currently working 24 hours per day Monday through early Saturday morning. This schedule will continue through December before shifting to a two-shift-per-day, eight-hour-per-shift schedule. 

Bulkheads

  • Bulkheads installation along RTA2 (middle section of the canal) is currently in progress. For the properties that the Gowanus Remediation Trust is leading, sheet are 89% done and tiebacks are 49% done. When the Trust finishes their bulkheads, they will move on to the Turning Basin 1 project and the other property owners will complete their bulkhead reconstructions.

Carroll Street Bridge

  • The Carroll Street Bridge construction started in April and is currently underway.
  • Expect the reopening of the bridge in early 2026.

Canal Design

  • The design for RTA2 has been finalized (9/17). Will post on the Site Profile Page in a few days. Natalie Loney will announce when it’s up.

Sheens at Head of the Canal

  • We are still working closely with the Trust to determine the source of the sheens and find a plan to mitigate the issue.
