4. Road Construction and Maintenance - continued

Some general principles to consider constructing stream crossings are :

• Design crossing to allow for fish passage and to protect water quality.
• Time construction to protect fish habitat and water quality.
• Design crossing to handle peak runoff and flood waters.
• Stream crossings should be at right angles to the stream channel and should include erosion protection measures.
• Crossings should be designed to protect the approach to the stream at the stream banks and stream bottom.

Note that federal, state or local agencies may require permits for construction of stream crossings.
