Inability to Completely Backfill Single-Sided Flashboard Structures

Backfilled Soil will slump as the angle of the bank exceeds the angle of repose for the soil type.

On taller structures, excess backfill will slide into the water and in front of the box blocking the entrance of the riser.

It’s completely normal and expected that the top of taller single-sided structures will be out in the water, away from the bank. This makes it more difficult to access the flashboards.
