• Embankment. Section 206.2(a)

• Sandbags. Provide sandbags as indicated, directed and approved by the Representative.

860.3CONSTRUCTION—As shown on the Standard Drawings, at the location indicated or directed, and

as follows:

downstream earthen or sandbag berm as indicated and directed. Inspect bag after each runoff event to ensure that the bag continues to function properly. Replace or remove and clean bag when sediment has accumulated to 1/3 full or when flow capacity has been reduced so as to cause flooding or bypassing of the inlet. Upon final stabil ization of tributary area , when directed, remove bag and downstream earthen or sandbag berm in a manner satisfactory to the Representative. Dispose of bag and sediment in a manner satisfactory to the Representative.

sandbag berm as indicated and directed. Inspect inlet protection after each runoff event to ensure that it continues to function properly. Remove and replace aggregate when it is contaminated with sediment, washed out, or as directed. Upon final stabilization of tributary area, when directed, remove inlet protection and downstream earthen or sandbag ber m in a manner satisfactory to the Representative . Dispose of sediment and materials in a manner satisfactory to the Representative.
