About this file

Written by GovTribe AI ·

This document is a civil engineering drawing for the Tomoka Farms Road Landfill 2024 Gas Collection and Control System (GCCS) Expansion, prepared by SCS Engineers for the Volusia County Solid Waste and Recycling Division Public Works Department. The drawing represents the existing conditions of the South Cell, detailing the current landfill gas infrastructure including extraction wells (EW), horizontal collectors (HC), air supply pipes, condensate discharge pipes, leachate sumps, and cell boundaries. The drawing is dated July 2025 and uses an aerial survey from June 28, 2023, with previous landfill gas collection system as-built drawings referenced from HDR (August 24, 2021) and Peavey & Associates (August 11, 2023, and January 24, 2025).

The technical drawing provides a comprehensive site plan with topographical contours, showing a detailed network of gas collection pipes ranging from 4" to 12" in diameter, multiple extraction wells, and associated infrastructure. The drawing includes a legend identifying various components such as existing wells, horizontal collectors, access risers, leachate sumps, and cell boundaries. The scale is 1" = 125' with north orientation, and the document is professionally sealed by a Professional Engineer named Stephanie M. Liptak, indicating compliance with engineering standards and regulatory requirements for landfill gas management and infrastructure planning.
