C~ 3.0 TECHNIQUE SPECIFlCATIONS 3.1 General • Areas outside the limits of the sites to be excavated, graded, end/or planted will not be disturbed by removal and restoration activities, excepting those areas specifically set aside for staging. Flagging will be used to Nsually delineate areas to be affected versus areas considered to be 'out-of-bounds'. On slopes accessible to common agricultural machinery, all operations will be conducted along the contour as governed by safety consideratlons. On such slopes accessible to construction equipment, but Inaccessible to agrtcultural machinery, all operations will be conducted so as to avoid creating conditions which Increase or enhance downslope surface or subsurtace flow patterns. On level or nearly level sites, as areal conditions permit, ell equipment operations and manual site preparation activities will be conducted perpendicular to the prevailing wind direction. 3.2 Rlpping Rlpping will be accomplished by a dozer equipped wish a single or twin set of ripper shanks. Ripping will be completed to a depth of ai least 1 toot, as specified, oh approximately 4-6-foot centers. Ripping will be completed at a speed which maximizes the action o} the ripper shanks end promotes material disruption to the required depth. Material type and compaction levels will be maJor factors in determining Vactor speed. 3.8 Seedbed Material Application Seedbed material will be applied es soon as possible after grading and/or ripping. Seedbed material to be applied will be that previously Identified as suitable for reapplication or that selected In the field for use by the revegetatlon supervisor. Equipment utilized will be capable of applying this material In the prescribed manner given slope, application depth, and areal extent as well as material characteristics. Seedbed material will be spread to an even depth as per resolling specifications. The number o} equipment passes over the site will be kept to the minimum necessary to properly complete material application and avoid unnecessary compaction. Seedbed materials will not be handled when such materials contain a moisture content which would Inhibit proper application or contribute fo excessive compaction. The surface of reapplied materials will be left In a roughened condition to Inhibit erosion while providing a proper surface for the application of subsequent revegetation techniques. 5
