Port Authority seeks revocable consent for flood‑barrier anchors near Holland Tunnel; Community Board 2 reviews plan

Representatives from the Port Authority of New York and New Jersey briefed Community Board 2’s Traffic and Transportation Committee on a revocable consent application to install recessed anchor sleeves in roadway and sidewalk pavement that would receive removable AquaFence flood‑barrier panels at locations near the Holland Tunnel.

What was proposed: Chris Lee and Ricky Ramirez of the Port Authority described anchor sleeves already installed near the Broome Street entrance to the Holland Tunnel and a pending revocable consent application with the New York City Department of Transportation to install additional anchors along the southern sidewalk of Canal Street between Hudson Street and Barrack Street (adjacent to the tunnel approach). Ramirez said the sleeves are installed flush with the sidewalk and roadway surface, capped to avoid trip hazards, and are intended to receive removable panels only when the Port Authority deploys the AquaFence system in advance of high‑water events.

Why it matters: The removable barriers are a storm‑surge mitigation component of a broader Holland Tunnel Superstorm Sandy repair and resiliency program. Port Authority staff said the barriers are designed to protect tunnel portals from surge events; crews will transport and install pre‑fabricated panels stored in crates and expect the phased deployment to begin roughly 72 hours ahead of a forecasted surge, with final portal closures dependent on intergovernmental decisions and forecasts.

Construction and schedule details provided - Scope: The committee was shown drawings of the Canal Street southern sidewalk segment (Hudson to Barrack) that remains pending DOT revocable consent; Port Authority representatives said roughly 95% of the anchors across both New Jersey and New York sides of the facility are already installed. - Installation depth and method: Representatives described drilling holes approximately 12 inches deep, installing sleeves, grouting and capping flush to the existing surface; work on the Canal Street section was estimated to take approximately five to seven nights of overnight work and require a right‑lane eastbound closure on Canal Street during those overnights with a pedestrian detour in place. - Barrier height and design standard: Port Authority staff said the panels are designed to a flood standard they identified as the 500‑year flood level (presentation slide); committee members asked for the exact numeric elevation and staff said they would provide the specification. - Maintenance/inspection: Port Authority staff said the portal barriers require annual inspection and maintenance; the agency will plan nighttime closures for inspections once construction concludes and will communicate closures in advance.

Committee questions and follow‑up Committee members asked how quickly barriers can be deployed once a severe‑weather forecast arrives; Port Authority staff said the standard deployment timeline begins about 72 hours before an anticipated surge and that full portal closures depend on timing and gubernatorial direction. Members asked about lifespan and durability of buried sleeves; Port Authority staff said sleeves have performed well in New Jersey installations and will be inspected annually and repaired or replaced as necessary. The Port Authority said the broader Holland Tunnel Sandy resiliency program cost about $364 million, with roughly 84% federal reimbursement; staff agreed to provide the committee a breakdown of the anchor‑installation cost and the numeric elevation used for the 500‑year design.

No formal board vote was taken on the revocable consent application at the committee meeting; Port Authority representatives said they are awaiting DOT action and that the application will proceed through the required municipal permit reviews and then to the Community Board full board as needed.

Quotations (selected) - Ricky Ramirez, General Manager, Holland Tunnel (Port Authority): “The finished surface is flush — the anchor gets installed, it gets capped, and there's no trip hazards.” - Port Authority presentation: “This AquaFence system is part of our Holland Tunnel Sandy repair and resiliency project…designed to protect the Holland Tunnel from a storm surge like we saw during Sandy.”

Ending note Port Authority staff said they will provide the committee the requested numeric flood‑elevation standard, installation cost figures for the anchor sleeves and scheduling details; Community Board 2 will include its review in the record and the Port Authority will pursue the DOT revocable consent and municipal permits before proceeding with overnight installation work.
