Document Description
Replace a failed culvert on Park Spur Road within the Mill Creek watershed of Del Norte Coast Redwoods State Park to repair the flood-damaged road and provide access to maintain power supply lines. Work will:
Remove up to 9 alder and conifer trees, ranging in size from 6 to 16 inches DBH, which have fallen onto adjacent banks and into the stream channel;
Use an excavator and bulldozer to remove 300 cubic yards of crossing fill and the failed culvert (excavation dimensions at the stream crossing will be approx. 60 feet wide, 15 feet deep, and 120 feet long);
Excavate the channel down to pre-disturbance gradient and install a new 8-foot diameter by 120 foot length corrugated steel pipe;
Use an excavator and/or bulldozer to backfill the new pipe in one-foot lifts and use a gas powered vibratory plate to compact the soil in succession until the culvert is buried and the road is built back up to grade;
Use an excavator to stack rip rap along the inlet and outlet of culvert to a minimum of 2 feet above the top of the pipe to protect and buttress the backfill;
Use an excavator to gather native mulch generated during tree removal and spread evenly over disturbed areas; and
Use dump trucks to import bas rock, a grader or bulldozer to spread base rock, and a vibratory roller to compact the final road surface.
