<strong>Boggs</strong> <strong>Mountain</strong> <strong>Demonstration</strong> <strong>State</strong> <strong>Forest</strong> <strong>Draft</strong> Management Plan, June 2008<br />
3. Install rolling dips between ditch relief culverts<br />
4. Maintain CMP culverts<br />
5. Armor outfalls from culverts and rolling dips<br />
6. Rock surface<br />
Site 3: Mile 0.35 to 0.55 (1056 ft.)<br />
Priority: Medium<br />
This section of road is insloped with an outside berm and an inboard ditch. The berm on the<br />
outside road edge channels surface runoff back onto the roadbed. There are several waterbars<br />
that drain surface runoff. Ditch relief culverts and waterbars have not been functioning properly in<br />
this section of road. The road grade on this section is 9-10%. The road prism can be outsloped<br />
but waterbars will still need to be retained and improved. Exposed rock throughout.<br />
Remedial treatments include:<br />
1. Outslope road surface<br />
2. Excavate outside berm and use spoil to fill inboard ditch<br />
3. Rock surface<br />
4. Armor drainage outlets Maintain CMP culverts<br />
5. Armor outfalls from culverts and rolling dips<br />
Site 4: Mile 0.55 (Jct. Rd. 210) to 1.05 (2112 ft.)<br />
Priority: Medium<br />
This section of road is insloped with an outside berm. There is minimal or no inboard ditch in this<br />
section. Existing drainage structures are spaced too far apart to be effective. Roadbed has<br />
developed rills and ruts from surface erosion. Exposed rock at .75, .95 miles.<br />
Remedial treatments include:<br />
1. Outslope road surface<br />
2. Install rocked rolling dips<br />
3. Excavate outside berm and smooth over roadway<br />
4. Armor drainage outlets<br />
Site 5: Mile 1.05 to 1.25 (Jct. Rd. 500) (1056 ft.)<br />
Priority: High<br />
This section of road is insloped with an outside berm. The Inboard ditch is practically nonexistent.<br />
Existing drainage structures are spaced too far apart to be effective. Roadbed has<br />
developed rills and ruts from surface erosion. Rolling dip at the junction of Road 200-500 needs<br />
to be recontoured in order to accommodate large vehicles such as log trucks, transports and fire<br />
engines. Junction Road 220 at 1.0 miles. Lots of exposed rock.<br />
1. Remedial treatments include:<br />
2. Outslope road surface<br />
3. Install rolling dips or rocked fords<br />
4. Excavate outside berm and smooth over roadway<br />
5. Armor drainage outlets<br />
6. Recontour and rock existing rolling dip<br />
