Bioengin eering Strategies

  • Coir fjber roll and reinforced fjber roll lifts add

stability and protection to the toe of a bank and provides a window of opportunity to establish vegetation.

  • Erosion control blanketing composed of natural fjbers are

used to stabilize soils above the fjber rolls allowing time for native salt tolerant plants become established.

Bioengin eering Strategies

  • Resists degradation from the marine environment.
  • Absorbs some of the force of wave energy unlike many hard solutions that defmect the energy
  • f wave action to surrounding areas.
  • Materials life-expectancy to stabilize sediments matches the time required to establish

native plants.

  • Utilizing a portion of the upper bank can create a more stable slope angle.
  • Adds increased stability and storm damage prevention to the bank.
  • Without this step, an investment in bioengeneering can be lost due to bank collapses.

St abilizing toe o f bank - Fib er r o lls

  • Installation begins at the base of the array and proceeds up bank.
  • Proper anchoring strategy to hold toe protection in place.
  • Synthetic fjlter fabrics DO NOT ENHANCE success of a bioengineering project.

  • Use of pre-vegetated fjber rolls along top of array.
  • Added vegetation to the root matrix.
  • Full season of plant growth prior to installation.

St abilizing soi ls abo ve t o e pr o t ec t io n

  • Native salt tolerant grasses are seeded into the bank prior to installation of erosion

control blankets.

  • The erosion control blankets protect soils from erosion and helps to retain moisture

to promote seed germination.
