The Vanderzyl Abandoned Mine Land (AML) Reclamation Project in Marion County, Iowa, encompasses approximately 61 acres of land requiring extensive earthwork and drainage improvements. The project includes site clearing and preparation, excavation of approximately 570,000 cubic yards of material, and implementation of sediment and erosion control measures such as wattles and temporary earth diversions. The reclamation design incorporates a traditional approach utilizing terraces (over 11,000 linear feet) and a comprehensive drainage system consisting of various sizes of HDPE pipes, concrete risers, and pipe outlets. The project also involves subgrade preparation with agricultural lime application, mulching, and specialized seeding for both upland (57.2 acres) and wetland fringe (3.9 acres) areas. Contractors should be prepared to handle diverse tasks including grading, pipe installation, erosion control, and vegetation establishment to restore the site to a stable, environmentally sound condition. The anticipated cost of construction to reclaim the site is expected to range from $1,650,000 to $1,850,000.

The Plans and Construction Specifications governing the construction of the proposed improvements have been prepared by Trihydro Corporation and are hereby made a part of this notice by reference and the proposed Contract shall be executed in compliance therewith.
