Top layer of stone will be removed from red areas. The US section of the left bank will then be sloped & all areas planted.

Removed stone will be then placed in the brown areas using the trenchfill technology to provide a “funnel” effect to prevent the stream from flanking the existing project.

Take the last scoop of soil dug from the trench & place
it back into the trench.
Mini-Case study: 4 of 8

TWO-STAGE SLIT TRENCH TECHNIQUE
Place willows & other water-loving species into
loose soil at bottom of trench. They are then less
likely to fall over when trench is backfilled.

Square stones (3 ft by 3 ft by 3 ft) placed with a sharp edge facing upstream, designed to “kick” flow off the bank, must be keyed into the bed & bank, spaced 6 to 8 ft apart, every 4th one should be keyed into
the bank. Every 4th stone has a Single Stone Bendway Weir.
