Low Impact Stream Crossings
What is it?
Stream crossings should be limited in number and cafefully designed to minimize damage to riparian areas, streambanks, stream hydrology, and stream habitats.
Conservation Benefits
- Minimizes impacts to stream habitats (like substrate and vegetation)
- Minimizes stream flow alteration
What does it include?
Stream crossings should consider these best management practices:
- avoid areas with imperiled species or sensitive habitats
- build at a right angle to the stream
- avoid altering streamflow
- use appropriately sized drainage structures to prevent changes in stream hydrology and promote fish passage
- minimize the use of equipment in streams and riparian areas during construction (reduction in sedimentation)
- stabilize banks and soils around the crossing after construction
- remove stream crossings once they are no longer needed
