and smothering of bottom organisms. Any accompanying shoreline, tidelands 

 or estuarine excavation should be minimized. Turbidity curtains (silt 

 curtains or diapers) should be placed so as to minimize siltation in 

 adjacent waters. Appropriate scheduling of bulkhead construction 

 activities can reduce any potential interference to aquatic organisms 

 during migration, spawning, and other important life phases.
