<br />3.0 TECHNIQUE SPECIFlCATIONS <br />3.1 General <br /> <br />Areas outside the limits of the sites to be excavated, graded, and/or planted will not be disturbed by <br />removal and restoration activities, excepting those areas specifically set aside for staging. Flagging will <br />be used to visually delineate areas to be affected versus areas considered to be °out-of-bounds°. <br />On slopes accessible to common agricultural machinery, all operations will be conducted along the <br />contour as governed by safety considerations. On such slopes accessible to construction equipment, but <br />Inaccessible to agricultural machinery, all operations will be conducted so as to avoid creating conditions <br />which Increase or enhance downslope surface or subsurface flow patterns. On level or nearly level sites, <br />as areal condkions permit, all equipment operations and manual ske preparation activities will be <br />conducted perpendicular to the prevailing wind directlon. <br />3.2 Ripping <br />Ripping will be accomplished by a dozer equipped with a single or twin set of ripper shanks. Ripping <br />will be completed to a depth of at least 1. foot, as specified, on approximately 4-6-toot centers. Ripping <br />will be completed at a speed which maximizes the action of the ripper shanks and promotes material <br />disruption to the required depth. Material type and compaction levels will be maJor factors In determining <br />Vactor speed. <br />3.3 Seedbed Material Application <br />Seedbed material will be applied as soon as possible after grading and/or ripping. Seedbed material <br />to be applied will be that previously identified as sukable for reapplication or that selected In the field for <br />use by the revegetation supeMsor, Equipment utilized will be capable of applying this material in the <br />prescribed manner given slope, application depth, end areal extent as well as material characteristics. <br />Seedbed material will be spread to an even depth es per resolling specifications. The number of <br />equipment passes over the site will be kept to the minimum necessary to properly complete material <br />application and avoid unnecessary wmpaction. Seedbed materials will not be handled when such <br />materials contain a moisture content which would Inhibit proper application or contribute to excessive <br />compaction. The surface of reapplied materials will be left In a roughened condkion to Inhibit erosion <br />while providing a proper surface for the application of subsequent revegetation techniques. <br />5 <br />
