About this file

This document is an engineering drawing depicting the existing conditions of the South Cell at the Tomoka Farms Road Landfill for Volusia County Solid Waste and Recycling Division, prepared by SCS Engineers in July 2025. The drawing provides a detailed site plan showing the landfill's current Gas Collection and Control System (GCCS) infrastructure, including existing gas extraction wells, horizontal collectors, air supply pipes, condensate discharge pipes, and leachate sumps. The contours are based on an aerial survey from June 28, 2023, and the landfill gas collection system as-built drawings from previous years (August 2021, August 2023, and January 2025).

The drawing includes a comprehensive legend detailing various infrastructure components such as existing wells (gas extraction, horizontal), access risers, leachate cleanouts, and cell boundaries. The site map is drawn at a scale of 1" = 125' with a north-oriented layout, showing the topographical variations of the landfill site. The document is digitally sealed by a Professional Engineer and is part of a 2024 GCCS Expansion project for the Volusia County Public Works Department, indicating ongoing infrastructure development and environmental management of the landfill site.
