Document Description
The primary purpose of the project is to improve the existing roadway and wet stream crossing to provide reliable access to the Applicant's residential parcel during all seasons. The project will eliminate the existing wet ford crossing so vehicles will no longer be driving directly through the muddy streambed. Road improvements include installation of two culverts. A 24-inch diameter and 30-foot long corrugated plastic culvert will be installed where the road crosses an intermittent stream channel and an 18-inch diameter and 20-foot long culvert will be installed at a location where water will flow during storm events. The 30-foot long culvert will be embedded six inches into the road bed and the 20-foot long culvert will be installed at the existing grade. Excavated soil will be incorporated into the 75-foot long roadway and a 75-foot long section of the roadway will be elevated approximately three feet with clean imported quarry rock. The inlets and outlets will be armored with rock. All work will occur within the existing 17-foot wide roadway.
