Updates on the Fourth Street Basin
Work is being planned at the extension of Fourth Street Basin by Whole Foods and the other side of the Third Avenue Bridge (National Grid is conducting the work). The Record of Decision (ROD) calls for the restoration of the Fourth Street Basin on the Park Slope side of the bridge.
- When EPA conducted the initial investigation, they only installed one sampling point to help identify the presence of contamination.
- During the design phase, EPA goes back and collects confirmatory information that might be needed to help in the design. EPA has now added six or seven additional borings to see how far the contamination goes toward Fourth Avenue.
- The borings are 50 feet deep. EPA is collecting soil cores, making observations, and sending them to lab for testing. EPA will also install wells for testing.
- The work in the Fourth Street Basin will evaluate methods for removing debris, while also removing all debris in the basin. The work is planned to start August 15 but will move toward the end of August or beginning of September. EPA will notify the community and businesses around the basin before starting work.
- EPA has received several requests from property owners who need to upgrade their bulkheads. One of them is at the Fourth Street Basin, at a property that used to be a scrap metal facility. The new owners will build a storage facility and want to upgrade their bulkheads. The second request is from 450 Union Street on the bridge side of Carroll Gardens – EPA has received preliminary drawings.
- EPA met with the City this week under a new order for the retention tank. This was an engineers’ meeting. EPA submitted additional requests for explanations of the City’s design; between now and the next meeting (in September), the goal is to define the basis of the design and resolve differences over how tanks will be built.
