Replace the crossing with a bridge or trestle to enable transport of sediment and wood downstream, and to improve fish passage. The U.S. Navy railroad crossing at Dickerson Creek is constructed on artificial fill that rises 40 ft. above the valley floor. Two metal culverts pass through the railroad embankment. The culvert outlets are perched due channel incision downstream. A fish ladder maintains passage to one of the culverts; however, the culverts are assumed to be velocity barriers during high flows and also pose passage problems during low flows. The crossing restricts conveyance of sediment and wood from upstream reaches. Sediment and wood accumulate on the upstream side of the railroad grade during floods and are removed from the channel by the Navy's routine maintenance.
