Project Description

Port Angeles Washington – Municipal Solid Waste Landfill Closure

  • Project: Port Angeles Landfill
  • Project Type: Municipal Solid Waste Landfill Closure
  • Location: Port Angeles WA
  • Owner: Port Angeles
  • Engineer: Herrera
  • Size: 19 acres

Preferred Cover System Alternative – Synthetic ClosureTurf®

  • Less refuse removal from the 304 Area due to steeper final cover slope (2.5:1) than compared to the traditional covers (3:1)
  • More refuse volumen that can be placed within the permitted boundary of Area 351, again based on steeper final cover slopes.
  • Cost savings associated with removing and discarding the cover system if additional refuse is required to be removed from 304 in the future
  • Cost savings associated with the lower maintenance required compared to the existing cover system and the traditional covers
  • Lower installation cost as compared to a traditional cover system
