Frattalone was hired by Waste Management to build a 20 ft high levee along the north side of the landfill to act as a break from river flood between the Minnesota river and the landfill. The west side of the levee will also act as the north wall of a future cell.
The material underneath the area of levee construction will have to be excavated down to bedrock or competent soils, hauled to the top of the landfill for future trash cover, and nearby stockpiles of compactible common will be hauled
back down and placed/compacted for a strong foundation for the levee to sit on. When the bottom is soil corrected, we will build a 3:1, 20-foot-high levee with a 14’ class 5 road on top along the length of it for access around the site. This will be a fast-paced excavation with material moving out and in at 660 yards per hour or 6,600 yards per day. The schedule has been a struggle from starting in the winter of 2023, shutting down due to frost. A wet 2024 spring
followed by an early summer flood from the Minnesota River having our site under 10 feet of water till late summer. Dan Sebesta and Lee Gass have been making progress this fall and are over halfway complete. Time will tell if we
are able to finish this winter or will this go into the Spring of 2025.
Some fun facts:
Levee soil correction – 186,500 yards
Levee one way haul build – 210,000 yards
Future cell floor soil correction – 43,500 yards
Future cell floor one way haul build – 8,000 yards
Build road on top of levee – 7,000 ton of rock import
