About this file

Written by GovTribe AI · Sep 24, 2025

The document is a staging and stockpiling map for the Los Reales Landfill project in Tucson, Arizona, prepared by SCS Engineers and issued for bid in January 2023. The map details two primary soil stockpile areas with specific capacity and configuration guidelines: Soil Stockpile #1 has approximately 70,000 cubic yards of available storage capacity with 1:1 side slopes and a maximum pile height of 40 feet, while Soil Stockpile #2 offers around 410,000 cubic yards of available storage capacity with 3:1 maximum side slopes and a maximum pile height of 60 feet.

The map illustrates the landfill's existing infrastructure, including active and future cell locations, maintenance buildings, and administrative facilities. The document provides detailed notes on topographic survey information, stockpile area specifications, and potential haul routing considerations. The staging area includes designated zones for construction soil stockpiling, contractor storage, green waste disposal, and existing asphalt millings. The map is part of the Cell 4B 2022 Construction project and includes existing grade contours, fence lines, buildings, roads, and permitted waste limits to provide a comprehensive site overview for potential contractors.
