Traffic, including bicycle lane, to be squeezed by Dean Street excavation between Flatbush and Sixth; new removable fencing to be installed to hasten work

According to a Supplemental Report (below) to the two-week Atlantic Yards look-ahead dated August 15, prepared by developer Forest City Ratner and distributed by Empire State Development, some 40' to 60' of the 16’ high fence on Dean Street between Flatbush and Sixth avenues will be removed, and replaced by "temporary 8 foot tall barrier consisting of plywood on Jersey barrier."

The reason? A safer and more portable fence is needed, over 30 to 45 days, to be moved daily to accommodate excavation for water and sewer piping.

Given that the excavation for the water and sewer piping will require a 25-foot trench from the face of the foundation to Dean Street centerline, traffic will be squeezed.

The upshot: part of the bicycle lane will be displaced:

Temporary traffic controls signage will be provided to alert bicycles and vehicles to “share the road”. Some parking on the south side of Dean Street will be removed for the duration of the work.

The 16’ high fence will be reinstalled after the piping is installed.
