4.0 Conclusions and Recommendations <br /> The results of this supplemental investigation supports the findings documented in the <br /> April 2"d report: the existing road cut-fill road section appears to be cut into bedrock with fill <br /> placed on the resulting bench. Furthermore, it confirms that the planned MSE wall will be <br /> underlain by bedrock as assumed in the preparation of the design drawings. <br /> Because the depth to and configuration of the bedrock surface beneath the existing <br /> roadway in some instances varies from what was assumed in the design, we recommend that the <br /> retaining wall be checked and the design be revised as necessary. <br /> Figures 3, 4, and 5 show the proposed finish grade of the new access road. The estimated <br /> top of bedrock elevation coupled with the planned new roadway grades indicates that MSE wall <br /> heights could be reduced by as much as 50 percent. <br /> 5.0 References <br /> Carroll & Lange-Manhard, 2013: Construction Plans, Mayday Idaho Mine Complex, Wildcat <br /> Road, La Plata County, Colorado.
