Roudybush East Mine Reclamation, Marion, Iowa
PSBA conducted design and construction observation services for the State of Iowa, Department of Agriculture & Land Stewardship, Division of Soil Conservation for the Roudybush East Mine Reclamation Project in Marion County, Iowa. This abandoned coal strip mine had collapsing high walls, acidic impoundments, clogged stream channels and threatened wetlands. The final design reclaimed 12 acres of this site. Work included re-grading the site to stabilized slopes, installing terraces, relocating wetlands, creating a 2 acre pond and stabilizing the high wall adjacent to a private residence. The mine spoil was treated with neutralizing lime and re-vegetated with warm season prairie grasses.
Bids were opened on March 1, 2013. Eleven bidders competed and the contract was awarded to the low bidder, K&N Excavating of Carthage, IL for $156,373. During construction, the Contractor encountered unknown underground mine rooms requiring shaft/room sealing and sub-surface drainage tiling.
The final project was completed in the Spring of 2014 at a final price of $159,319.
Roudybush East is the 7th abandoned mine land reclamation project designed and constructed by PSBA for the Iowa Division of Soil Conservation.
