PURPOSE & DESCRIPTION

The Filtrexx ® Channel protection soft armoring system is designed to stabilize and prevent erosion of channel beds and banks used for storm water conveyance and concentrated fow situations. The Channel protection technology provides structural protection, erosion control, vegetation growth, and vegetation reinforcement in the same system. The Channel protection weight and anchoring system can withstand storm water velocities and hydraulic shear stresses similar to traditional soft armoring devices (turf reinforcement mats, rip rap, cellular confnement systems). The Vegetated Channel protection system is specifcally designed to reinforce vegetation against intense hydraulic pressure. Once vegetation is established in the Channel protection, the following storm water management parameters are increased:

• structural stability of the channel and protection system,

• reduction of bed and bank erosion, • protection from scour erosion, • control of runoff velocity, • dissipation of runoff energy,

• sediment, soluble pollutant, and pathogen removal effciency

APPLICATION

Filtrexx ® Channel protection is used where storm water is conveyed/channeled and soil erosion and/or vegetation stability is an issue. Channel protection is used to establish & reinforce vegetation in areas of concentrated fow and intense hydraulic pressure that typically undermine vegetation growth. Applications

include:

• storm water diversion channels and ditches, • storm water conveyance channels and ditches, • channel/ditch bed and bank protection,

• outlet protection for storm drains, paved channels, and culverts.

INSTALLATION

1. Channel protection shall meet Filtrexx ® Channel protection Specifcations and use Filtrexx ® GrowingMedia tm .

2. Contractor is required tobe a Filtrexx ® 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. Channel protection will be placed at locations indicated on plans as directed by the Engineer.

4. Channel protection must be installed and stabilized before fow is allowed from culverts and storm outlets.

5. Land surface shall be cleared of debris, including rocks, roots, large clods, and sticks prior to Channel protection installation.

6. Channel bed soil shall be compacted, graded, and made smooth prior to installation of Channel protection.

7. Upslope end of Channel protection shall be installed under culvert lip or outlet drain to ensure initial water contact is on top of Channel
