b. Where site work is occurring in the active or inactive flood- 

 plain, scheduling should allow for work suspension and removal 

 of equipment, materials, and stockpiles from the floodplain 

 during spring breakup or other predictable flood events 



4. After incorporating the conclusions from the four levels of deci- 

 sions from Section I into a final site selection, a site investi- 

 gation (described in Appendix B) should be conducted to: 



a. Verify that the candidate site can produce the quantity and 

 quality of desired gravel 



b. Collect hydraulic measurements such as discharge, channel 

 cross sections, and bed material size distribution whenever 

 possible to assess the hydraulic conditions of the natural 

 channel (see Appendix B). 



c. Determine the presence or absence of limiting fish and wild- 

 life habitat within the project site. Analysis should be based 

 on annual biological requirements (i.e., fish spawning and 

 overwintering habitat). 



d. Flag site boundaries and buffer locations in preparation for 

 an agency site inspection. Flagging should be highly visible, 

 of weather resistant material, and maintained through site 

 operation and closure. 



• Mark site boundaries on mature trees in timbered areas with 

 some highly visible material (such as paint or cloth 

 mater i a I ) . 



• For flagging in the open-water season use l-m metal stakes 

 or rods driven approximately 0.5 m into the ground with 



a red flag of approximately 15 x 15 cm attached
