PURPOSE & DESCRIPTION

The Filtrexx ® Bank stabilization vegetated soft armoring system is designed to stabilize banks, and prevent erosion of waterway and shoreline banks . The Bank stabilization system is composed of a heavy duty tubular mesh netting matrix used to contain and reinforce growing media and vegetation. The Bank stabilization technology provides structural protection, erosion control, vegetation growth, and vegetation reinforcement in one system. The Bank stabilization weight and anchoring system can withstand storm runoff velocities and hydraulic shear stresses similar to traditional soft armoring devices, while the injected GrowingMedia tm and optional drip tape irrigational system ensure establishment and sustainability of both seeded and live stake plantings. The Bank stabilization system will provide: structural stability/protection from toe-cutting and sloughing of waterway bank; structural stability/protection from mass wasting and sloughing of shoreline from wave action; control of erosion from overland runoff, wave action, and shear stress from concentrated fows; control of runoff velocity fowing to receiving water; dissipation of runoff energy fowing to receiving water; sustained vegetation health; sediment, soluble pollutant, and pathogen removal of runoff fowing to receiving water.

APPLICATION

The Bank stabilization armoring system is used where waterway and shoreline banks are eroding, are unstable, or cannot sustain vegetation. Bank stabilization is used to establish and reinforce

vegetation where fows and intense hydraulic pressures typically undermine vegetation. Applications include: creek, stream, riparian bank stabilization; pond, lake shoreline stabilization; sediment, storm water retention/detention pond bank stabilization; riparian, stream bank, tidal creek, salt marsh restoration, habitat/ecological restoration, aesthetic revitalization.

INSTALLATION

1. Filtrexx ® Bank stabilization shall meet Filtrexx ® Bank stabilization Specifcations and use Filtrexx ® GrowingMedia tm .

2. Contractor is required tobe aFiltrexx ® Certifed tm Installer as determined by Filtrexx ® International, LLC (440-926-2607; www.fltrexx.com). Certifcation shall be considered current if appropriate identifcation is shown during time of bid or at time of application (list found at www.fltrexx.com). Look for Filtrexx ® Certifed tm Installer Seal.

3. Bank stabilization will be placed at locations indicatedonplans as directedby theEngineer and will be fabricated on-site.

4. Bank stabilization shall be placed in amanner that protects the entire bank or shoreline from erosion and destabilization.

5. Bank stabilization must be installed and stabilized before concentrated fow is allowed to contact bank or slope area.

6. Sediment control devices (such as Filtrexx ® Sediment control) shall be installed if construction requires land disturbance or earth moving.
