The permit applicant, Suffolk County Department of Public Works (SCDPW), has requested
Department of the Army (DA) authorization to conduct dredging, with ten-years maintenance with
placement of all resultant dredged material upland with return flow to the waterway. The project is
located at Police Marina in Nicoll Bay in the Town of Islip, Suffolk County, New York.
The proposed work would involve the following:
Maintenance dredge with ten-years maintenance, by hydraulic dredge, approximately 6,000 cubic
yards (CY) from a 56,917 square foot area consisting of an approximately 130-foot-wide by 900-footlong
channel to a depth of seven feet below the plane of Mean Low Water (MLW). The approximate
slope of the channel would be 1 to 3. The dredged material would be placed at an upland dike
disposal area at Heckscher Park, with a return pipe to the waterway.
The applicant plans to conduct three (3) additional dredging events within the ten-year maintenance
dredging period removing a maximum of approximately 6,000 CY per event from within the same
dredging area with the same disposal area.
The applicant has stated that they have avoided, minimized, and mitigated for potential impacts
proposed to the maximum extent practicable by limiting the dredged area to the minimum area
required for safe and reasonable navigation of Police Marina in Nicoll Bay. Any potential impacts
would be temporary and would be offset by implementing best management practices associated
with the proposed use of a hydraulic dredge. The use of a hydraulic dredge would provide the
cleanest and least obtrusive method for sediment removal and transport, minimizing to the greatest
extent possible any potential adverse effects to the aquatic environment.
The stated purpose of this project is to maintain safe navigable depths for vessel use in the waterway.
