Maintenance Dredging of Fire Island Inlet and Shores Westerly to Jones Inlet, New York Beach Erosion Control and Navigation Project

Background Information:

The U.S. Army Corps of Engineers, New York District (the Corps) proposes to perform maintenance dredging of the Federal Navigation Channel and deposition basin in Fire Island Inlet with placement of the dredged material as beach nourishment along the feeder beach (Gilgo) west of the Fire Island Inlet. The channel was last dredged in 2024, with the removal of approximately 1,510,000 cubic yards (CY) of sand, which was used in a beneficial manner as beach erosion control and hurricane protection placed along Gilgo Beach, Overlook Beach, and Tobay Beach. The proposed maintenance dredging and beach nourishment would involve the removal of approximately 3,000,000 CY of sand, which would be used in a beneficial manner as beach erosion control and hurricane protection placed along the feeder beach (Gilgo).

The channel and deposition basins will be dredged to a depth of 14 feet below mean lower low water (MLLW) plus 2 feet allowable over depth (see Figure 1). The proposed dredging for this cycle is anticipated to occur in the fall/winter of the dredging year, subject to the availability of funds.

The purpose of the proposed work is to alleviate the efects of shoaling and maintain the authorized project dimensions, thereby providing safe and economical use of the Fire Island Inlet by commercial and recreational boating interests while providing beneficial use of the dredged material. Between maintenance operations, the physically bypassed sand placed at the feeder beach would be carried by littoral drift to feed down drift beaches. This maintenance operation would thus serve to place sand trapped in the channel back into the normal littoral movement that naturally replenishes the western beaches and protect Ocean Parkway, while also restoring a safe channel for navigation.

Maintenance dredging of the channel and deposition basin at Fire Island Inlet is usually accomplished by pipeline dredge (cutterhead). The entire channel will generally not require maintenance dredging; only areas where shoaling has reduced the depth of the channel will require dredging.

Once the contract is awarded, the contractor will be required to commence work within five (5) calendar days after the date of receipt by him of the notice to proceed and maintain an integrated production rate of at least 13,500 cubic yards per calendar day for the dredging and placement of the dredged sand. The presence of dredging equipment in the channel will impact ship trafic, and it is necessary to maintain this production rate while minimizing the duration of this impact.

The proposed work is anticipated to take place in the fall/winter of 2026/2027. The work is estimated to cost between $25,000,000.00 and $100,000,000.00.
