Restoration of a Construction-Scarred Duneby Jay Sturgill, US Army Corps of Engineers, Portland, OR, USA,
Abstract: The rehabilitation and extension of the north and south jetties at the entrance to Siuslaw River required the contractor to stockpile jetty stone in nearby surge piles in order to maintain a high placement rate. The plan called for stone fragments to be removed, original contours of the beach and dune areas to be reestablished, and for vegetation similar to that in adjacent undisturbed areas to be established over the entire disturbed area. A critical element of this plan was the erosion control afforded to the foredune area of the beach by quick reestablishment of beach grass in the dune. Other key elements of the plan are the retention of the upland dune area in its natural state and the acceleration of the successional process in the reestablishment of beach and dune vegetation. An artificial environment was created by fertilizing and mulching, and by irrigating.
