REVERSE GRADE NOTES:

I. CREATE A ROLLING TRAIL THAT DIPS AND RISES

FREQUENTLY.

2. LOCATE REVERSE GRADE AT LOCATIONS PER

WORK DESCRIPTION AND/OR WHENEVER THE

GROUND WILL ALLOW.

3. THE TRAIL GRADE MUST ALWAYS REMAIN LE55

THAN 15% (NO FINISHED GRADES ABOVE 15% WILL

BE ALLOWED WITHOUT PRIOR WRITTEN APPROVAL

FROM COR).

4. ROUTE THE TRAIL ON THE UPHILL SIDE OF

ESTABLISHED TREES TO UTILIZE THE BENCH AND

AVOID THEIR ROOTS.

5. USE NATURAL OBSTACLES TO PROVIDE

BARRIERS TO SURF AROUND.

� Design Parameters Design Parameters are technical guidelines for the survey, design, construction, maintenance, and assessment of Nationaf Forest System trails, based on their Designed Use and Trail Class and consistent with their management intent1

• Local deviations from any Design Parameter may be established based on trail-specific conditions, topography, or other factors, provided that the deviations are consistent with the general intent of the applicable Trail Class.

1 For definitions of Design Parameter attributes (e.g., Design Tread Width and Short Pitch Maximum) see FSH 2309.18, section 05.

2 The determination of trail-specific grades, surface, and other Design Parameters should be based upon soils, hydrological conditions, use levels, erosion potential, and other factors contributing to surface stability and overall sustainability of the trail.
