Title
Intergovernmental Agreement Between City of Buckeye and City of Phoenix for City of Phoenix Municipal Solid Waste Landfill Located in Buckeye - Amendment (Ordinance S-47904)
Description
Request to authorize the City Manager, or his designee, to amend Intergovernmental Agreement 100744 between the City of Buckeye and the City of Phoenix, for the City of Phoenix Municipal Solid Waste Landfill located in Buckeye, to allow for Phoenix to raise the height of the landfill to 225 feet above the existing grade from the previous maximum of 150 feet above the existing grade.
Report
Summary
In August of 2002, the City of Buckeye annexed the property where SR85 Landfill is now located. The purpose of the original Intergovernmental Agreement (IGA) between the City of Buckeye and the City of Phoenix was to clarify responsibilities related to the operation and management of the SR85 landfill, operated by the City of Phoenix, but located in the City of Buckeye.
The IGA includes 12 site design and operational conditions. A modification to the first condition is proposed. This condition currently limits the height of the landfill to a maximum of 150 feet above the existing grade. The requested change of this design stipulation would allow for Phoenix to raise the height of the landfill to 225 feet above the existing grade.
The reason for this request is to address the current levels of excess soil stockpiled, while maintaining landfill volume after waste settlement. As currently designed and permitted, construction of the landfill will generate approximately 17,000,000 cubic yards of excess soil, which has a capital requirement to excavate and stockpile and would ultimately lead to an expense to haul off the site. Amending this design requirement allows the landfill to balance the soil surplus generated and maintain the airspace volume required for disposal.
Some of the benefits of this modification include reduction of the depth below ground surface for excavation, to bring soil surplus into balance and ensure the landfill capacity is not reduced. This agreement with the City of Buckeye will result in better management of the soil surplus at SR85.
On July 6, 2021, the City of Buckeye City Council approved the request to amend the IGA with the City of Phoenix to raise the maximum height of the landfill to 225 feet above the existing grade.
Financial Impact
There is no cost associated with this amendment.
