Marine Corps Reserve Center (MCRC) Floyd Bennett Field

The Challenge

Our team provided coastal revetment design services for Marine Corps Reserve Center (MCRC) Floyd Bennett Field. The facility shoreline along the northern edge of Jamaica Bay was comprised of steel sheet piling which was severely corroded. Significant erosion and destabilization of the fill material located behind the sheet pile wall occurred due to wave action and scouring through wall breaches and corrosion holes.

The Solution

TN & Associates contracted with us to prepare the geotechnical investigation and sheet pile structural evaluation, gather the required oceanographic/meteorological data, and to perform the design calculations for rock revetment construction. We prepared construction drawings depicting existing conditions, proposed grading, cross-sections and stormwater management controls; prepared design calculations for stormwater management controls; completed revetment slope stability and construction geotextile evaluations; prepared civil discipline technical specifications; and provided assistance with the New York State Department of Conservation Joint Application for Permit.

Our team also provided construction support including assessment of potential armor rock sources, field QA/QC methods, and review of constructed components for conformance with the design.
