Project Experience

Lizard Rock Designs, LLC – Los Reales Landfill Entrance Facilities Design and Permitting Services

Helping to establish an extensive waste management campus at existing landfill

Lizard Rock Designs, LLC Los Reales LandfillCornerstone has provided design and permitting services for development of a new entrance facilities campus at the Los Reales Landfill in Tucson, Arizona. The extensive campus includes scale house facilities, a public drop-off/transfer facility, recycling facilities, an administrative building, a Materials Recovery Facility (MRF), and associated roadways and infrastructure.

The landfill entry reconfiguration project is designed to increase safety on the site and working face, separate commercial from self-haulers, encourage recycling and reuse of materials, and encourage development of “cottage industries” to divert waste from the landfill. The project will be LEED Certified at a Silver level. As a part of this effort, Lizard Rock Designs (LRD) led a series of design workshops with city staff, commercial haulers, and self-haulers to study traffic flow at the entry and onto the working face of the landfill itself.

More than 48 options were studied, and consensus was reached on one that allowed commercial haulers to proceed directly to the landfill, while keeping self-haulers below at a convenience center and recycling facility.
