In areas where soil is not available for <br />replacement or where surface materials are suitable, areas will not be ripped to a depth that exposes <br />any undesirable underlying materials. If this depth is less than six inches, then soil will be added to <br />attain a minimum depth of six inches. In areas where broadcast seeding or hydromulching is to be <br />employed, the soil surfaces will be left somewhat roughened condition. Dozers or other tracked <br />equipment may be used to prepare the surface for hydromulching or broadcast seeding. If the <br />seedbed surface is hard and crusty, then tracked equipment will be used to roughen the surface prior <br />to hydroseeding or broadcast seeding. <br />TR -77 H-2 Revised March 2019 <br />
