The on -site location may need to be adjusted to meet field conditions in order to utilize the most suitable outlet . Concentrated flows should spread over the widest possible area after release . Flows with .. high sediment concentrations should pass througha sediment trapping measure . (See Plate 4 . 17b ) Construction Specifications 1 . The diversion shall be installed as soon as the right-of-way has been cleared • and/or graded . 2 . All earthen diversions shall be machine- or hand -compacted in 8-inch (20 cm) lifts . +� 3 . The outlet of the diversion shall be located on an undisturbed and stabilized area when at all possible . The field location should be adjusted as needed to utilize a stabilized outlet . Sediment laden flows shall be conveyed to a sediment trapping device . 4 . Earthen diversions which will not be subject to construction traffic should be slibkmd in accordance with TEMPORARY SEEDING - Section 6 . 65 ( ES BMP 1 .65) . .r Maintenance The practice shall be inspected after every rainfall and repairs made if necessary . .r Approximately once every week, whether a storm has occurred or not, the measure shall be inspected and repairs made if needed .
