DEP1700000006 Lyburn (Maynard) Drainage PLANS.pdf

This is a technical plans document prepared by the West Virginia Department of Environmental Protection's Abandoned Mine Lands and Reclamation program for the Lyburn (Maynard) Drainage project. The document contains engineering drawings and cross-sectional details for a drainage infrastructure system designed to address abandoned mine land reclamation. The plans include typical wall sections, open-graded crushed stone leveling pad specifications, and structural details for the drainage system components. Key design elements shown in the drawings include underdrain pipe cross-sections, pipe trench configurations with both vegetated and aggregate surface options, pipe clean-out details, and Type "G" inlet specifications positioned at multiple locations throughout the system.

The technical specifications and construction details outlined in the plans establish the standards for materials, installation methods, and system configuration for the drainage project. The drawings indicate the use of structural backfill (SB) materials at specific depths, aggregate materials for select trenches, and standardized inlet designs throughout the system. No pricing information, contract timelines, bid response dates, or award details are contained within this technical document, as it serves primarily as the engineering specification resource for potential contractors undertaking the drainage construction work associated with the Lyburn (Maynard) project.
