Former Gladsky Marine Site

This site remediation is the second to the last brownfield in the city’s 52-acre Waterfront Revitalization Area (WRA). Under the current land development agreement (LDA), the redeveloper’s plans for the WRA include 860 residential units, a 250 suite luxury hotel including banquet and meeting facilities, a luxury spa and restaurant; 50,000 square feet of office space, 25,000 square feet of retail space, 85 new boat slips, trolleys servicing nearby bus and rail stations, and nearly 20 acres of public-accessible open space along the waterfront and adjacent to the Garvies Point Preserve.

Open Space

The open space network provides for a continuous esplanade and open space ribbon along the entire length of the north side of Glen Cove Creek, connecting the project site to Glen Cove’s Downtown. The Gladsky site is now suitable to become part of the planned green space and pedestrian park.

Site Contractor

After completing the necessary Phase I and Phase II environmental evaluations, the City of Glen Cove Community Development Agency (CDA) completed the competitive bidding process and selected the lowest responsible bidder, EnviroTrac, Ltd,. as the prime contractor to commence remedial construction of the Former Gladksy Marine Site, located at 51 Garvies Point Road in Glen Cove, New York. The site, which is currently vacant, was previously home to the Gladsky Marine business, a marina and marine repair facility from the early 1970s until 1999.

Investigation Results

Results of investigations performed at the site identified the presence of semi-volatile organic compounds and metals exceeding allowable standards, criteria, and guidelines (SCGs) within surface and subsurface soils throughout the site. Additionally, a portion of the site along the existing bulkhead was found to contain asbestos containing materials (ACM) within surface and subsurface soils.


Construction efforts were partially funded through grants obtained under the United States Environmental Protection Agency (USEPA) Brownfield Cleanup Grant Program and the New York State Department of Environmental Conservation (NYSDEC) Environmental Restoration Program. Additional funding was provided through an agreement between Nassau County and the CDA utilizing USEPA Brownfield Revolving Loan Funds. These programs are designed to provide assistance to municipalities for the reimbursement of investigation and remediation costs to promote redevelopment of blighted areas for commercial, industrial, residential, or public reuse.

Remedial Activities

Substantial completion of remedial construction activities was achieved on November 19, 2010, consistent with the approved project schedule. As part of post-remediation efforts, CDA will have its consulting engineer prepare a Final Engineering Report for submission to the NYSDEC, which will describe the cleanup activities completed and certify that cleanup requirements have been achieved. Additionally, as part of these efforts, a  Site Management Plan (SMP) shall be prepared to address residual contaminated soils that may be excavated from the site during future redevelopment,evaluate the potential for vapor intrusion for any building that may be erected during future redevelopment, and identify any use restrictions.  An environmental easement will also be imposed on the site as part of post-construction efforts to enforce the Site Management Plan (SMP).
Remedial construction activities included:
  • Demolition of onsite wood-frame structure, including disconnection of existing utilities
  • Closure of existing on-site sanitary Underground Injection Control (UIC) structure
  • Excavation and proper offsite disposal of semi-volatile organic compounds (SVOCs) and metal contaminated soil exceeding site-specific SCGs, with a minimum of two feet of soil removed across the site
  • Excavation and proper offsite disposal of asbestos-containing soils located along the existing bulkhead, with a minimum of two feet of soil removed from this area
  • Excavation, removal, and proper offsite disposal of a buried underground gasoline storage tank encountered during excavation activities
  • Removal and proper disposal of above-ground and buried miscellaneous debris
  • Collection of confirmation soil samples to determine final excavation depths, as well as confirm achievement of site-specific cleanup goals (NYSDEC Part 375, Restricted Residential Criteria)
  • Placement of backfill materials obtained from an offsite, certified clean source to achieve proper grading heights (All backfill materials must be tested to confirm that did not contain contaminants.)
  • Final site restoration consisting of the placement of six inches of topsoil and grass seed across the entire area of the site                      

Special Thanks

The CDA would not have been able to accomplish this project without the collaborated efforts and assistance of the USEPA, NYSDEC, the County of Nassau, Glen Cove Department of Public Works, and our environmental consultant Dvirka and Bartilucci Consulting Engineers.
