Plans > Landfill Development Plan (2020)

Plan Overview

There are three major development phases in the conceptual cell layout for the Plan. Each phase includes multiple individual landfill cells. Phase 1 includes the developed landfill area (Cells 2A, 2B, 3, and 4) and future Cell 5. Phases 2 and 3 are divided into corridors, which may contain two or three landfill cells each, depending on operational preferences as phasing progresses (e.g., cell life). Phase 2 is located south of Phase 1 and includes seven corridors. Phase 3 is located east of Phases 1 and 2 and includes eight corridors. This corridor orientation throughout the Landfill development takes advantage of piggybacking airspace over existing waste.

Plan Justification

This is an update of the current landfill development plan and any recommended changes, incorporating conceptual design of leachate and landfill gas (LFG) management systems, and the feasibility of select leachate treatment and LFG reuse options. The Plan provides a summary of the data, assumptions, and approaches that were used in the conceptual layout and cell sequencing for the Central Landfill (CLF).
