Written by GovTribe AI · Aug 31, 2026

This is a set of engineering plans and bid specifications for an Abandoned Mine Land (AML) reclamation project prepared by the Iowa Department of Agriculture and Land Stewardship, Division of Soil Conservation and Water Quality, in partnership with the U.S. Department of the Interior Office of Surface Mining Reclamation and Enforcement. The project encompasses two sites—Noah AML and Wilcox East AML—located in Marion County, Iowa, within sections 4, 5, 8, and 9 of Township 74 North, Range 18 West. The scope of work includes site clearing and preparation (106.5 acres), excavation (1,347,611 cubic yards), installation of terraces (16,734 linear feet total), installation of drainage infrastructure including PPHP, HDPE, and PVC pipes, riprap placement (2,538 tons), wetland creation and restoration (5.0 acres undercut and replacement), seeding with native and wetland plant mixes (103.2 acres), field fencing (4,734 linear feet), and sediment control measures. The project was designed by Shive-Hattery, Inc. and issued on August 18, 2026, with bid number IA-113-363. The engineer's contact is listed as Shive-Hattery, Inc. at 4125 Westown Parkway, Suite 100, West Des Moines, Iowa 50266, phone (515) 223-8104.

The contractor is responsible for all survey layout, control, mobilization, construction dewatering, utility verification, and compliance with the Storm Water Pollution Prevention Plan (SWPPP) requirements and Department of Natural Resources NPDES permit conditions. A Section 404 Nationwide Permit has been obtained by the Division. The project includes five surveyed control points established by Shive-Hattery, Inc., with elevations based on NAVD 1988 datum. Contractors must provide at least 48 hours notice to the engineer prior to commencing construction and are required to complete detailed grading within specified tolerances. The contract includes incidental costs for property monument replacement, construction debris disposal, all disturbed area restoration, tree protection, and grade adjustments for shrinkage factor variations. Specific restrictions include no tree clearing between April 1 and September 30, no ponding of water except at proposed impoundments, and coordination with Marion County regarding right-of-way work. The project is funded through grant number S25AF00167 from the U.S. Department of the Interior.
