  19. Bioengin eering Strategies M a terials fo r S tabilizi n g C o as tal B ank s • 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.

  20. Bioengin eering Strategies M a terials fo r S tabilizi n g C o as tal B ank s • Robust anchoring systems.

  21. Bioengin eering Strategies M a terials fo r S tabilizi n g C o as tal B ank s • 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.

  22. Bioengin eering Strategies M a terials fo r S tabilizi n g C o as tal B ank s • Resists degradation from the marine environment. • Absorbs some of the force of wave energy unlike many hard solutions that defmect the energy of wave action to surrounding areas. • Materials life-expectancy to stabilize sediments matches the time required to establish native plants.

  27. Install ation & Case Studies I mp ortance o f Establ is h in g a S t ab le S lo pe • 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. (MA CZM Storm Smart Properties Fact Sheet 4) 1 2

  28. Install ation & Case Studies 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. 1 2 3

  29. Install ation & Case Studies St abilizing toe o f bank - P r e-veget a t ed fiber r ol l s • Use of pre-vegetated fjber rolls along top of array. • Added vegetation to the root matrix. • Full season of plant growth prior to installation. 1 2 3

  30. Install ation & Case Studies 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. 1 2 3 4 LITTLEBLUE SWITCH- SIDEOATS STEM GRASS GRAMA
