Remove debris, rocks, clods, etc.. Ground surface should be smooth prior to installation to ensure log remains in contact with slope. Step 2 - Staple Selection At a minimum, 1" long by 1" by 24", stakes are to be used to secure the log to the ground surface. Installation in rocky, sandy or other loose soil may require longer stakes. Place RECP along slope to provide upstream apron for log. Secure RECP according to standard slope installation instructions including upstream anchor trench. Secure log to blanket, ensuring log remains in intimate contact with the RECP over the length of the installation. A minimum of one foot upstream apron and two foot downstream apron are required for installation. Subsequent, downslope rows of logs should be spaced appropriately for site conditions to minimize acceleration of flow. Further, log seams are to be offset to ensure continuous filtration. Figure A presents a schematic of a slope installation in profile view. Slope Installation Place RECP along channel to provide upstream and downstream apron for log identically to slope installation.
