IESI – Seneca Meadows, Inc. – Site and Civil Design for Dove Wetland Mitigation, Wetland Remediation
Stream relocation accommodates facility development
Cornerstone personnel worked with Seneca Meadows Landfill, Inc. (SMI) on the development of a 540-acre wetland mitigation site required by the U.S. Army Corps of Engineers and the New York State Department of Environmental Conservation (NYSDEC) to mitigate the impact to 70 acres of low quality wetlands associated with the expansion of the Seneca Meadows Landfill. Cornerstone personnel worked with the client and specialty wetland consultants to select the mitigation site and develop appropriate supporting documentation for the permitting and approval of the wetland mitigation project.
Supporting documentation included natural resources studies, wetland delineation, flood mapping, and brook relocation plans. Cornerstone personnel also developed grading plans for the 540-acre site to create appropriate topography and grading that would support multiple wetland vegetative zones. Our work included development of a Stormwater Pollution Prevention Plan that included establishment of erosion and sediment control measures for earthwork operations covering 195 acres, and involved the cut/fill of more than 600,000 cubic yards of subsoil and topsoil material.
The wetlands mitigation project has been completed and Cornerstone prepared final construction certification documents for submittal to the regulatory agencies. The project’s success has been demonstrated by the return of a diverse population of flora and fauna.
