Checklist
for Success |
|
|
|
| |
The following is a partial list of practices
that may be applicable to road construction during your forest management
project. Implement the appropriate practices to protect water quality before,
during and after the project is completed. Refer to the Forest Water Qualilty
Guidelines for a more complete list of practices. |
|
 |
| |
Planning |
|
| |
- Use the minimum number of roads to meet transportation needs.
- Design roads for safety, the intended purpose and the specific site.
- Avoid wetlands unless impractical. Keep wetland constraints in mind.
- Design roads to fit the natural terrain.
- Locate and construct road surfaces to drain naturally.
- Don't make roads too steep.
- Plan enough drainage features at suitable locations.
- Place excavated materials in stable areas.
- Use stream crossings only when necessary, and when used, be sure
they will accommodate peak water flows.
|
|
| |
During
construction |
|
| |
- Start work timely to avoid wet and winter seasons, if possible.
- Install drainage features at time of road construction.
- Compact all fill material.
- Allow adequate drainage from road surface.
- Use live vegetation or slash to prevent erosion of fill material
and to prevent surface runoff from entering live streams.
- Stablize disturbed areas as soon as practical.
- Consider surfacing to prevent road surface erosion or excessive maintenance.
|
|
| |
Road
Maintenance |
|
| |
- Maintain drainage of road surface. Avoid leaving a berm which might
cause standing water or channel surface runoff down the road.
- Grade roads only when necessary. Avoid cutting toe slopes and creating
excess material.
- Surface road if appropriate to reduce erosion and rutting if road
is used in
all types of weather.
|
|
| |
Stream
Crossings |
|
| |
- I n stall crossings during appropriate season to minimize effects
on water quality.
- Consider low flow periods and impact to fish populations.
- Identify appropriate type of stream crossing.
- Install stream crossing appropriately whether ford, culvert or bridge.
Protect integrity of existing stream channel.
- Place rock, gravel, slash or other material along streamsides to
protect the fill material, culvert inlet and outlet and bridge abutments
from erosion.
|
|
| |
Skid
Trails |
|
| |
- Use fewest number of skid trails possible to limit soil disturbance.
- Use appropriate skidding systems for terrain, i.e. rubber-tired skidders,
tractors, cable, etc.
- Avoid skidding patterns that might concentrate or channel runoff.
- When skidding is terminated, consider water bars and seeding if erosion
might become a problem.
|
|
| |
Landings |
|
| |
- Avoid landings in Streamside Management Zones.
- Minimize number and size of landings.
- Locate landings away from natural drainages and divert runoff away
from streams.
- Construct landings to allow for natural drainage to occur.
- Locate landings to preclude skidding through drainages and streams.
- At the end of operations, restore landings and reseed if necessary.
|
|
| |
Winter
Operations
|
|
| |
- Use winter season for low-impact logging of sensitive areas.
- Construct roads during summer or fall months to insure compaction
of fill material.
- Provide adequate drainage for winter operations as well as other
seasons.
- Use cold weather to solidify roads and prevent damage to moist areas.
- Suspend operations during periods of alternate freezing and thawing.
|
|
| |
When roads, streams crossings, landings,skid
trails or winter operations have
ended, consider the closing of such facilities. Rehabilitation of the area
and
revegetation is strongly recommended to prevent erosion and subsequent
impact to water bodies in the area. |
