c. When vegetated areas cannot be avoided, it is usually desir- 

 able to locate material sites in large stands of homogeneous 

 mature vegetated areas 



d. The site should be located on the same side of the floodplain 

 as the material use point. This will minimize the need for 

 crossing of active channels. 



3. All work scheduling should attempt to avoid conflicts with sensi- 

 tive biological events and extreme hydrological events.

 locations and configurations. 



a. In general, work should be scheduled to avoid peak biological 

 events, such as local fish migration and spawning, and bird 

 and mammal breeding, nesting, and rear i ng-of-young. For ex- 

 ample, site clearing of vegetation should occur in fall to 

 avoid the sensitive spring and early summer avian nesting 

 season. Occasions may occur when gravel removal operations 

 should be suspended to avoid disturbance to an essential 

 b io I og i ca I event .
