Seepage A A ,No evidence orhistoryof unrepaired seepage, saturated areas, orboils. No seepage was noted during inspection. M IEvidmee or history of minor unrepaired seepage or small saturated areas at or beyond the i lardside toe but not on the landward slope of levee. No evidence of soil fratsport. U Evidence or history of active seepage, extensive saturated areas, or boils. If there is significant growth on the levee that inhibits the inspection of animal bestows or other items, the inspection should be ended until this item is corrected. Detailed survey elevations are normally required during Periodic Inspections, and whenever there are obvious visual settlements. s The decision on whether or not USACE inspectors should enter a pipe to perform a detailed inspection must be made at the USACE District level. This decision should be made in conjunction with the District Safety Office, as pipes may be considered confined spaces. This decision should consider the age of the pipe, the diameter ofthe pipe, the apparent condition of the pipe, and the length of the pipe. if a pipe is entered for the purposes of inspection, the inspector should record observations with a video camera in order that the condition of the entire pipe, including all joints, can later be assessed. Additionally, the video record provides a baseline to which future inspections can be compatred. Key: A = Acceptable. M = Minimally Acceptable; Maintenance is required. U = Unacccptabic.
