The City of Troy identified a property containing an abandoned, unlined landfill for development of a golf course and driving range facility. The project attracted significant public participation because a rare lake prairie wetland is immediately adjacent to the proposed development. The wetland is home for the Eastern Box Turtle, rare orchids and other endangered species.
Project Scope The city retained NTH to perform an initial environmental investigation and to prepare a Baseline Environmental Assessment (BEA). NTH’s role expanded as the project continued. We performed additional environmental, geotechnical, design, and construction services throughout the development and construction phases until the project was completed.
Project Approach NTH first completed a full scale evaluation of environmental conditions at the site including an analysis of the impact of leachate on groundwater and adjacent wetlands and ponds.
NTH then prepared a closure plan for the landfill, in compliance with PART 201 “Due Care” requirements, that included:
Placing a clay cover over the landfill
Installing passive methane vents
Instead of capping the entire site, NTH performed a detailed investigation that carefully delineated areas that may need additional capping. This saved over $400,000 in closure costs.
The NTH project team helped the city address public concerns and attended several public meetings to answer questions about the proposed development and its impact on wildlife. Our team also supported the city during preparation of construction plans and bidding, and provided construction quality assurance and certification.
