About this file

The document is an Exhibit A Landfill Fact Sheet for the City of Phoenix, detailing information about seven landfill sites located in Arizona: SR 85, Skunk Creek, 27th Avenue, 19th Avenue (Cells A and A-1), Del Rio, and Deer Valley. The landfills vary in size from 14 to 2,654 acres, with opening years ranging from 1946 to 2006, and all are currently closed. The sites have different historical uses and future plans, including potential park areas, radio towers, and a golf course.

Each landfill has unique characteristics regarding refuse buried (ranging from 2.5 to 19.5 million tons), landfill gas collection systems (primarily flare systems with one using activated carbon capture), and groundwater monitoring frequencies (from none to quarterly). The landfills are situated in different council districts and have varying numbers of landfill gas (LFG) wells, probes, and sumps. Most sites have implemented environmental monitoring systems, with end-use plans that include future recreational developments or repurposing of the land. The fact sheet provides a comprehensive overview of the City of Phoenix's landfill infrastructure, highlighting the city's approach to waste management and environmental stewardship.
