Apply <br />appropriate seed mixture. <br />2. Install TRMs after application of seed, mulches (if applicable) and other soil amendments, <br />unless soil in- filling is required. If soil in- filling is needed, install TRM, apply seed and <br />other amendments and brush or rake topsoil into TRM matrix. <br />3. Anchor top of blanket at end of channel section using trench and/or staples /stakes. <br />4. Unroll center blanket in direct of water flow on bottom of channel. Securely fasten blanket <br />to soil surface with staples /stakes in accordance with manufacturer's staple pattern guide. If <br />available, use colored dot pattern corresponding to the manufacturer's recommended staple <br />pattern. If applicable, overlap adjacent blankets and staple. <br />5. Anchor full - length margin of blankets at top of side slopes with a row of staples /stakes. <br />Backfill soil material over final 12- inches of blanket margin and compact. <br />• <br />2.05.3 -E2.20 <br />
