There are several considerations that apply to nearly all stream and crossings. Do not cross unless absolutely necessary. If it is necessary to cross a or wetland, the number of should be limited to as few as possible and the location should be carefully selected. Existing crossings should be used whenever possible, unless their and use would be more damaging than establishing a new one.
The crossing should be as as possible. Stream crossings should be to the direction of water to the degree practical. Wetland crossings should be to the direction of water flow to the degree practical. Approaches to crossings should be direct and have a low grade. Water diversion , such as a broad-based dip or water bars, should be constructed to direct water flowing down the road or skid into a vegetated area before it reaches the crossing. This will help minimize the movement of into the water body.
Stream crossings should be located on a straight of the stream channel that has banks. This will minimize the need to disturb the bank or to alter the natural of the channel. It will also reduce the impact of water action against the crossing structure itself or against any portions of the bank that need to be disturbed to permit installation of the structure. Where there is a risk of , structures should be anchored at one end to allow them to swing out of the main channel without washing downstream or water flow.
Proper installation, , and site rehabilitation are essential for any crossing option to be fully effective. All necessary should be obtained in advance and terms communicated clearly to the employees or working on the crossing.
