About this file
This is a bathymetric survey map prepared by Great Lakes Dredge and Dock Company for the Fire Island Inlet project (GLDD Job No. 15771). The map displays depth contours and survey data for a borrow area divided into four contract zones: Channel Contract Area, Contract Area A, Contract Area B, and Contract Area C. The survey was conducted on March 3, 2019, using US Survey Feet as the unit of measurement with vertical datum referenced to Mean Lower Low Water (MLLW) and horizontal datum based on NAD-83 State Plane coordinates for New York Long Island (NY-3104 Zone).
The map indicates depths relative to MLLW, with areas shallower than 14 feet marked in red and designated as potential obstructions. Magnetic survey targets are identified as both high and low priority areas, with given US Coast Guard obstruction locations marked with circular symbols. The document serves as a submittal survey for dredging operations, providing essential bathymetric data for project planning and execution in the Fire Island Inlet area.
