MKCs02 - Cass Highwall

MANDATORY PRE-BID MEETING ON SEPTEMBER 29, 2026, AT 10:00 AM. Project Name: Cass Highwall Project Description: The Cass Highwall Project is located in Cass Township, Muskingum, Ohio. Directions to the site are as follows: From Zanesville, take Northpoint Drive for 7.4 miles. Turn left on McGlade School Rd. Go 0.6 miles, Turn right onto Schneider Lane. The addresses are 9425 Schneider Lane Dresden, Ohio 43821 and 9417 Schneider Lane Dresden, Ohio 43821. The project’s latitude and longitude are 40.088942°, -82.03795°.
The Project includes a series of legacy, undrained highwall impoundments resulting from surface mining operations in the 1950’s and early 1960s. The intent of the reclamation project is to reduce the hazards associated with surface mine highwalls and impoundments, create positive drainage, and restore the mined areas to a more stable, functional land configuration. The highwall impoundments have been assessed and determined to pose a hazard on the public and the overall project goal is to mitigate those hazards.
The primary project work includes:
* Drain existing mine pits and backfill exposed highwalls using available mine spoils to establish stable, positive drainage. * Construct dedicated drainage channels within valley regions to control surface runoff. * Establish a permanent sediment pond at the drainage channel outlets, by constructing an engineered embankment dam and integrated emergency spillway on the western boundary.
Major work items: * Impoundment Dewatering – Approximately 2.7 Million Gallons (Mgal). * Site Preparation and Restoration - Clearing, grubbing, and subsequently revegetating approximately 32 acres.
* Earthwork - Approximately 155,000 Cubic Yards (CY) of earthwork to eliminate highwall impoundments and create positive drainage. * Channel Stabilization – Approximately 11,000 Square Yards (SY) of geotextile or protective channel lining * Embankment Construction – Approximately 4,200 Cubic Yards (CY)) of embankment fill for permanent sediment pond.
Other work items include installation of underdrains and aggregate drains (as needed), rock excavation, tree planting and revegetation of the site prior to completion of the project.
The project officer for this project is Laura Cross in the Cambridge Office (614) 230-3783, and the project engineer is Ron Warner, P.E. in the Cambridge Office (740) 740-255-1028.
