4. Material sites within the active f I oodp I a i n should: 



• Not disturb the edge of the active channel (s); 



• Maintain a high-water channel shape, within the material site, 

 similar to that which enters and leaves the site; 



• Not increase the bed slope of active or high-water channels 

 local ly to more than that of natural ly occurring slopes; 



• Form new high-water channels through the site if flow is expected 

 through the site; 



• Be shaped and contoured to provide proper drainage; 



• Have material stockpiles, overburden piles, and dikes removed 

 from near active channels unless they have a specific purpose for 

 being there and are designed to withstand the hydraulic forces; 

 and 



• Be protected from low flow channels until the occurrence of the 

 first flood after the site is completed.
