Road Condition Information Definitions Road designated level and Maintenance:

Level 2. Assigned to roads open for use by high clearance vehicles. Passenger car traffic, user comfort, and user convenience are not considerations. Warning signs and traffic control devices are not provided with the exception that some signing, such as W-18-1 “No Traffic Signs,” may be posted at intersections. Motorists should have no expectations of being alerted to potential hazards while driving these roads. Traffic is normally minor, usually consisting of one or a combination of administrative, permitted, dispersed recreation, or other specialized uses.

Log haul may occur at this level. Appropriate traffic management strategies are either to:

a. Discourage or prohibit passenger cars, or

b. Accept or discourage high clearance vehicles.

Definition of Road Maintenance Level 2

Road maintenance level 2 is defined in the FSH 7709.59, sec. 62.32 as:

“Assigned to roads open for use by high-clearance vehicles. Passenger car traffic, user comfort, and user convenience are not considerations. Warning signs and traffic control devices are not provided with the exception that some signing, such as W-18-1 “No Traffic Signs” may be posted at intersections. Motorists should have no expectations of being alerted to potential hazards while driving these roads. Traffic normally is minor, usually consisting of one or a combination of administrative, permitted, dispersed recreation, or other specialized uses.

Log haul may occur at this level.”

Appropriate traffic management strategies are encouraged, accept, discourage, and prohibit.

Maintenance level 2 roads have the following attributes:

• Are maintained for use by high-clearance vehicles and not suitable for passenger cars.

• Do not consider passenger car traffic, user comfort, and user convenience.

• Have low traffic volume and low speed.

• Typically, are local roads that connect to collectors and other local roads.

• Have dips or cross drains as the preferred drainage treatments.

• Avoid the use of culverts, arches, and bridges when possible.

• Typically, have very few, if any, signs or other traffic control devices.

• Are subject to the requirements of EM-7100-15 and MUTCD for all signs.

• Do not consider surface smoothness.

• Do not always provide motorists with alerts to potential hazards.

• May not be passable during periods of inclement weather.

Maintenance level 2 prescription guidelines:

Traveled way. Log out and brush only as necessary to provide passage for high-clearance vehicles.

Maintain road prism for drainage and to provide for passage of high-clearance vehicles. Traveled way should only be bladed to maintain drainage functionality and not to provide a smooth surface for passenger cars.

Shoulder. Shoulder is usually not defined and maintenance is not required unless necessary to maintain structural integrity of the roadway, drainage functionality, or access by high-clearance vehicles.

Drainage. Drain as necessary to keep drainage facilities functional and prevent unacceptable environmental damage while maintaining passage for high-clearance vehicles.

Roadway. Remove or rampover slides and repair slumps as needed to provide access for highclearance vehicles and to control resource damage.

Roadside. Generally no work is required unless necessary to provide clearance for existing traffic.

Fallen trees may be left in place if not an obstacle to safe passage of intended traffic.

Structure. Maintain all structures to provide for the passage of high-clearance vehicles and to protect natural resources.

Traffic service. Install and maintain route markers. Maintain warning, regulatory, and guide signs, and other traffic control devices as warranted in the sign plan to provide for existing traffic and the appropriate traffic management strategy. Generally, few, if any, signs or other traffic control devices are required.

Example only:

Figure A—Maintenance level 2 single-lane road with pit-run surface. This road is currently passable by high-clearance vehicles at low speeds and there is no evidence of significant erosion. No immediate maintenance is needed and future surface and shoulder maintenance activities should be limited to maintaining passage by high-clearance vehicles and to keep drainage features functional.

Figure B—Maintenance level 2 single-lane road with pit-run surface. The surface on this road is maintained adequately for high-clearance vehicles at low speed, and there is no evidence of erosion. However, the vegetation on the shoulder is beginning to encroach onto the traveled way and should be maintained to allow for access by high-clearance vehicles and maintenance equipment. The grass growing on the road surface is acceptable since it is not affecting passage.

Figure C—Maintenance level 2 single-lane road with native surface. While the surface on this road is extremely rough, it is still passable by high-clearance vehicles at low speeds. Generally, no additional surface maintenance is required unless unacceptable environmental damage due to erosion or widening occurs.

Figure D—Maintenance level 2 single-lane road with native surfacing that has motor vehicle use restricted by a gate. The surface and shoulders of this maintenance level 2 road are adequate for access by high- clearance vehicles at low speeds, and there is no evidence of significant environmental damage. A gate is an appropriate closure devise for maintenance level 2 roads that temporarily restrict all motor vehicle use or that are managed as administrative use only roads. If motorized or nonmotorized use, such as bicycles, occurs behind a gate, the back side may require signing also.
