Attachment 3 - Clearing Limits Diagram (AUG 2026).pdf

This document is a technical specification sheet and project layout for the Chicago Trail Belt Railroad Project, issued by the USDA. The project involves clearing units at various locations along a trail system, with detailed specifications for vegetation management, erosion control, and habitat restoration work. The document includes comprehensive tables outlining clearing objectives, disposal methods, and success criteria for different units, along with technical drawings and cross-sections showing site conditions, slope treatments, and erosion control measures such as erosion control blankets, slope drains, and sediment barriers.

The specification emphasizes environmental compliance and sustainable practices, requiring contractors to implement measures that prevent sediment loss, protect water quality, and restore native vegetation. Key technical requirements include clearing specified units, removing debris according to disposal method designations, installing erosion control devices, and achieving vegetation establishment targets within defined timeframes. The drawings depict typical slope configurations, drainage patterns, and the placement of erosion control materials at various elevations. Success criteria are quantified by percentage vegetation cover requirements and survival rates for planted materials. This appears to be a design and specification document rather than a solicitation, providing contractors with technical guidance and performance standards for implementing the trail restoration project.
