The Expansion Proposal: What you need to know


Coffin Butte Landfill’s 2024 expansion application is the culmination of more than two years of active listening and understanding, dialogue and consideration, and planning that incorporates feedback from various community stakeholders whenever possible.

Highlights of this proposal include:

  • An expansion that is 50 percent smaller than the 2021 proposal;
  • Protecting and improving Coffin Butte Road;
  • Increased transparency, communication and community responsiveness;
  • Improved vegetative screening along major travel corridors;
  • Containing the Landfill’s working face and disposal area to the Landfill Site (LS) zone; and
  • Continuous, reliable and affordable disposal capacity while the County aligns on a solid materials management plan (SMMP).
