OFF RIGHT–OF-WAY

WATER MANAGEMENT & Other Impacts

• Driveways• Logging Access• Farm field access• Pipe-lines• ATV trails• Field Outlets• Wet-weather channels• Drain tile• Other waterways (ag, natural, etc)

TYPES OF OFF-ROW INFLUENCES






• Brings excess water to road area–Saturates road base–Creates potholes– Increases erosion in road ditches

• Transports unwanted sediment to the road drainage system

• Lack of smooth vehicle transitions cause damage to roadway

IMPACTS OF OFF-ROW INFLUENCES




BANKS: PROBLEMS WITH COMMON PRACTICES

IGNORING OFF ROWCONCERNS













WHY IS IT IGNORED?• Legal issues• Landowner issues• Cost




PROBLEMSIncreased water on your road!– Saturation of road base (potholes, etc)– Excessive erosion of ditches and outlets– Water brings additional sediment

Prior to working off of the Right-of-Way:

• Talk with and gain approval of landowner

• Announce intentions and reasons at monthly public meeting

WHEN:

• Unwanted sheet flow is entering road area

• A safe and stable outlet is available for swale


PROS:– Improved drainage of surrounding land– Diverts water from road drainage system– Prevents water from eroding bank– Should not interfere with property use

CONS:– Concentrates surface water (need stable outlet)– Landowner issues
