Planning and Road Placement
This website should be consulted before putting in a road to see the properties of soils.
Web Soil Survey
Roads with steep grades should not lead directly towards what?
Stream Crossings
This structure should be utilized when necessary to allow drainage and water movement through the road.
Culvert
These temporary structures may be considered when a winter road will cross a definite drainage and be used for several years
What are temporary culverts or bridges?
This type of road is kept for long-term access and usually remains in the landscape after harvesting is complete
What is a permanent road
Name 3 factors that affect where roads should be placed?
Soil characteristics, distance from streams, grades of slopes, obstacles, and the function of the road, etc.
Portions of roads that have steep grades should be checked often while possibly adding what to the road to avoid erosion and rutting
Gravel (3 inches minimum)
If road construction must be completed through a wetland area, fill dirt should be taken from this higher elevation area.
What is an upland
This temporary winter stream crossing is made by pushing and packing snow into the stream and applying water so it freezes
What is an ice bridge?
These roads are built for short-term timber sale access and are typically retired once operations are completed
What is a temporary road
Check dams are generally constructed of rock and may be necessary to reduce the velocity of flow where?
In ditches and concentrated flow areas
What should be done when creating roads in low topography areas?
Road should be crowned
This material should be used underneath the fill material in wet areas with thick organic layers to prevent damage.
Fabric and or stone.
These conditions are required for ice bridges to remain usable, limiting them strictly to winter operations
What are continuous freezing conditions?
What are pre-seeded erosion control products at the toe slope of a road and at the outlets of culverts to regulate water flow? (General Term)
Erosion Barriers
What is the desired grade percentage for roads?
Answer: 2-10%
What types of logging equipment should be utilized when accessing or harvesting in a wetland?
Harvester/Processor
Ice bridges may not be appropriate on large water bodies or locations prone to these seasonal events.
What are high spring flows?
How far away from a wetland should equipment staging areas be located?
100 ft
Ice bridges are generally best used on streams with these characteristics: low flow rates, thick ice, or this type of channel in winter.
What is a dry channel?
