Mulch will be provided by CONTRACTOR, and will conform to Section 20.2 of the Revegetation <br />Specifications, attached. All mulch must be certified as noxious weed free or noxious weed <br />seed free by any authorized State or County Officer. Documentation of certification shall be <br />provided to the PROJECT MANAGER prior to application of mulch. <br />The mulch must be evenly distributed over the surface of dirt placed following excavation, and <br />at the working surface east of Ditch 8. <br />Severe surface roughening will occur simultaneously with distribution of the weed free mulch in <br />order to prevent loss of the mulch due to wind. <br />In order to accomplish the degree of severity of roughening required, the following will be <br />accomplished by CONTRACTOR: <br />Apply two (2) tons per acre weed free mulch per above; <br />Scarify the surface by using a track excavator bucket to gouge or pull the dirt and <br />mulch toward the machine in a manner so that no less than twelve inches (12") of <br />vertical relief is created. These gouges must be sufficiently close so that no more <br />than twelve inches (12") exists between the crest of one gouge and the crest of an <br />adjacent gouge, in any direction. <br />Roughening in this manner will occur at all fill generated by excavation during this Project, and <br />at the working surface immediately east of Ditch 8. <br />Following surface roughening, the Project Area will be revegetated. In addition to the <br />revegetation specifications outlined in Section 20.0 of the General Bid Specifications, the <br />following requirements will be adhered to: <br />Seed <br />Seed will be provided by the OWNER. <br />Fertilizers <br />Commercial fertilizer is required for this project. Fertilizer shall be provided by CONTRACTOR <br />and shall conform to Section 20.2 (commercial fertilizer) of the Revegetation Specifications, <br />attached. <br />Mulch <br />An additional two (2) tons per acre certified weed free wheat straw mulch will be supplied by <br />Contractor. <br />Seedbed Preparation <br />Seedbed preparation was accomplished as a result of the surface roughening. <br />Seed, Fertilizer and Mulch Distribution <br />CONTRACTOR will hand broadcast the seed, fertilizer and mulch in order to achieve an even <br />distribution of each material over the roughened slopes. Seed and fertilizer application rates will <br />be specified in the field by Project Manager. The mulch will be hand crimped. <br />Revegetation efforts will occur on approximately one (1) acre. <br />
