Woodland Roads
Roads, skid trails and landings are all part of a woodland transportation
system. Skid-trail and landing BMPs are covered in Timber
Harvesting. Properly constructed roads can provide woodland
access for such activities as managing timber, improving fish and
wildlife habitat, fighting fires and recreation.
Woodland roads that are poorly located, constructed or maintained
are the largest source of nonpoint source pollution from woodland
management activities. Roads over steep slopes, erodible soils
or stream crossings hold the greatest potential for degrading water
quality.
Planning, Location and Design
Decisions at the planning stage will affect a road’s construction
cost, long-term maintenance needs, service life and the amount of
nonpoint source pollution it causes. Landowners, managers
and operators should plan, locate and design the road system together.
I. Plan an overall road system that minimizes the number, width
and length of roads to limit the disturbance of the site.
Remember to:
A. use temporary roads where practical,
B. consider future uses of the road system,
C. coordinate development with adjoining landowners
II. Use existing roads when they provide the best long-term access.
A.
Do not disturb stable road surfaces.
B.
Reconstruct existing roads to the extent necessary to provide adequate
drainage and safety.
C.
Consider relocating existing roads if doing so improves access and
reduces
environmental impacts.
III. Locate roads outside streamside management areas except at
stream crossings.
IV. Identify optimum stream-crossing locations before locating the
rest of the road.
Optimum locations include
straight and narrow stream channels with low banks
and firm rocky soil.
Roads should approach streams at the least gradient possible.
V. Minimize the number of stream crossings.
VI. Locate roads on well-drained soils, where possible.
VII. Locate roads to follow natural contours and to minimize cut
and fills.
Balance cut and fills
to minimize the need for fill or removing excess materials.
VIII. Select road locations that allow for drainage away from the
road.
IX. Road grades should not exceed 5%. If road grades greater
than 5% are necessary,
limit grade length to
minimize erosion, or break the grade using drainage structures.
Refer to the Drainage
Structures section. Graveling the road surface on steep grades
can also help maintain
stability.
