<strong>Boggs</strong> <strong>Mountain</strong> <strong>Demonstration</strong> <strong>State</strong> <strong>Forest</strong> <strong>Draft</strong> Management Plan, June 2008<br />
Road 210<br />
Mileage begins at top of ridge and proceeds south and east to junction of Road 200.<br />
Site 1: Mile 0.0 to 0.3 (1584 ft.)<br />
This section of road is insloped with an outside berm. There is no inboard ditch nor ditch relief<br />
culverts in this section. Existing drainage structures (waterbars) have failed due to winter use.<br />
Roadbed has developed rills and ruts from surface erosion. Some waterbars will need to be<br />
retained and repaired to adequately drain this stretch of road.<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 2: Mile 0.3 to 0.5 (1056 ft.)<br />
This section of road is insloped with an outside berm with no inboard ditch. Existing waterbars are<br />
responsible for all road surface drainage. The road grade on this section is relatively flat, @ 0%<br />
slope. Exposed rock at .3 miles, major rill erosion at .5 miles, below landing. Ruts from vehicle<br />
tracks. Waterbars need to be installed and/or maintained.<br />
Remedial treatments include:<br />
1. Outslope road surface<br />
2. Excavate outside berm and smooth over roadway<br />
3. Armor drainage outlets<br />
4. Retain and improve existing drainage structures<br />
Site 3: Mile 0.55 to 0.8 (1320 ft.)<br />
This section of road is insloped with an outside berm with no inboard ditch. Existing waterbars are<br />
responsible for all road surface drainage. Road grade on this section is –17% going downhill from<br />
landing, and –10% below the rocky section. Major mud bog at mile .85 where road grade is flat.<br />
Numerous rocky sections and areas of exposed parent material at 0.7 mi. Waterbars need to be<br />
installed and/or maintained to provide adequate drainage.<br />
Remedial treatments include:<br />
1. Outslope road surface<br />
2. Replace existing waterbars with rolling dips<br />
3. Excavate outside berm and smooth over roadway<br />
4. Armor drainage outlets<br />
Site 4: Mile 0.9 to 1.0 (528 ft.)<br />
Priority: High<br />
This section of road is insloped with an outside berm with no inboard ditch. Existing waterbars are<br />
responsible for all road surface drainage. The road grade on this section is approximately 9%.<br />
No drainage outlets present.<br />
Remedial treatments include:<br />
1. Outslope road surface<br />
