National Program of Inspection of Non-Federal Dams, Tennessee. 8th Avenue Reservoir (Inventory Number TN 03719), Cumberland River Basin, Nashville, Davidson County, Tennessee. Phase I Investigation Report

摘要

8th Avenue Reservoir is in the high hazard and small size classification and according to OCE guidelines must pass the 1/2 to full PMF. Because the only inflow would be the rainfall itself, the reservoir, with its three feet of freeboard, would be able to contain the full PMP of 29.3 inches. The reservoir appeared to be in good condition and structurally stable. No significant seepage, wet areas, sinkholes or cracks were found on or near the reservoir. Seepage was occuring in the dry well of the gate house and calcium carbonate deposits were observed on the exterior stone of the reservoir wall; however, neither considered serious at this time. Structure is given a condition classification of 'deficient' because of the seepage in the gate house well and the minor concrete spalling on the walkway of the reservoir.
