Fire Island Inlet to Montauk Point Reformulation Study
The shoreline along the south shore of Long Island, NY between Fire Island Inlet and Montauk Point has a long history of damages due to beach erosion and coastal storms, notably from Hurricane Sandy in 2012. This report is considered a General Reevaluation Report (GRR) because there is an existing, authorized project for the area, formulated in the 1950s, that was partially constructed in the 1960s and 1970s, based upon the 1960 authorization. A Reformulation effort to revisit the authorized plan and identify a long-term solution to manage the risk of coastal storm damages was initiated in 1980, subsequently suspended, and then resumed in 1994. A Final Environmental Impact Statement and GRR was drafted and released in February 2020. A Report of the Chief of Engineers was submitted to the Secretary of the Army for transmittal to Congress in July 2020; a final record of decision was signed in September 2020. The recommended plan includes sand bypassing and dredging, renourishment, breach response plans, mainland nonstructural measures, removal of Ocean Beach groins, and coastal process features for 12 barrier island and two mainland locations.
