C4d_Attachment D Dam Repair Map.pdf

This document is a technical specification drawing for the Pounds Hollow Dam Seep Repair project located in the Shawnee National Forest. The drawing illustrates the downstream face of the dam and provides detailed construction specifications for repairing seepage issues at the dam.

The repair work involves constructing a seep cutoff at the downstream face of the dam with specific material requirements and dimensions. The design includes a 6-foot-high by 10-foot-wide section using 12-inch compacted IL CA-05 aggregate as the primary layer, with 12-inch compacted IL CA-06 aggregate as the base layer, sloped at a 2½:1 ratio. Key construction notes specify that dimensions are for estimating purposes only, with the Forest Service to stake the actual work location in the field before work begins. Excavation must begin 2 feet above the seep elevation, and all excavated material shall be reserved and used as fill. All disturbed areas must be raked smooth, seeded, and mulched upon completion. This technical specification document supports the Pounds Hollow Dam Repair project and was drawn on 7/2026.
