About this file
This document is a bathymetric map and survey clearance plan for the Fire Island Inlet Contract 1 dredging project. The map depicts the Fire Island Borrow Area with detailed contour lines, monitoring areas, deposition basins, and dredge zones. The project involves Great Lakes Dredge & Dock Company (GLDD) performing dredging operations under federal contract W912DS-21-C-0018. The survey was completed on March 21, 2023, and uses State Plane NAD-83 (New York Long Island 3104) as the horizontal datum with MLW (Mean Low Water) as the vertical datum, measured in US Survey Feet at a scale of 1:400.
The map identifies critical features including navigation channels, three primary deposition basins (A, B, and C), an Eastern Deposition Basin, and an EBB Shoal Dredge Area. Required monitoring areas are marked as G#1, G#3, G#5, G#7, G#9 and R#2, R#4, R#6, R#6A. The contours indicate a design grade depth of 14 feet MLLW with overdepth allowances to 16 feet MLLW. Additional markings show US Coast Guard obstructions (indicated by red circles) and locations where GLDD encountered hard material during survey work. The document includes station markers along the dredge area alignment ranging from STA 0+00 to STA 91+88.71, providing precise positioning for dredging operations and environmental monitoring compliance.
