About this file
The document is an engineering site plan for the Tomoka Farms Road Landfill 2024 GCCS (Gas Collection and Control System) Expansion project, prepared for the Volusia County Solid Waste and Recycling Division Public Works Department. The site plan, dated July 2025, depicts the existing North Cell of the landfill, showing detailed infrastructure including gas extraction wells (EW series), horizontal wells (HC series), leachate cleanout risers, condensate sumps, and various pipe networks. The drawing includes contour lines, existing cell boundaries, and a comprehensive legend detailing the types and locations of infrastructure elements.
The site plan is based on an aerial survey from June 28, 2023, and incorporates as-built drawings from previous landfill gas collection system implementations by HDR and Peavey & Associates. The plan highlights the complex underground infrastructure, including air supply pipes, condensate discharge pipes, landfill gas headers and laterals, and horizontal collector pipes. The detailed mapping suggests a comprehensive approach to landfill gas management, with multiple access points, extraction wells, and monitoring systems strategically placed throughout the North Cell of the facility.
