The intent of the Johnson Run Portals project is to fill and cap two open portals and a vertical shaft with polyurethane foam and native soil. Temporary stream crossings will be utilized to access the Salem Hollow site. The Combo Perry Co. Reclamation 2024 project is located on U.S. Forest Service land. Site access shall be from existing Township & County roads. Major work items in this project include, but are not limited to: * Clearing and Grubbing, including chipping, removal and windrowing of stumps and stacking of logs. * Installing Tied Concrete Block Channels. * Backfilling open portals with Polyurethane Foam (PUF) and native soils. * Earthwork required to backfill two highwalls. * PUF and native soils to backfill shaft on USFS. * Seeding and mulching of sites Engineer's Estimate: $605,490.00 Project Location: Starting at the intersection of S.R. 93 and S.R. 155 in Shawnee, Ohio travel East on S.R. 155 for 0.4 miles and turn left onto East Street/Iron Point Road (C.R. 44).
