Necanicum Riparian Restoration & Tree Release

Coho Creek is a tributary of the Neawanna Creek in the Lower Necanicum River watershed.  The project site is a fish passage barrier culvert under a 20 foot tall road fill on Spruce Loop Road leading to Seaside Heights Elementary School.  The barrier culvert is upstream from beaver pond rearing habitat and blocks access to potential coho salmon, cutthroat trout, and possibly winter steelhead, spawning habitat.  The 5 foot diameter round culvert will be replaced with a 19 foot span open bottom arch built at a minimum of 1.5 times bankfull width with a natural stream bottom.  The new culvert will provide fish access to 0.4 miles of stream habitat.
