Areas to be <br />reclaimed must be prepared by grading and shaping to achieve smooth surfaces •Nhich will not <br />concentrate or pond storm runoff and create long-term erosion concerns. <br />Topsoil shall be placed over subsoils which have been ripped to a depth of six inches <br />immediately prior to topsoil placement to promote mixing and adhesion of the topsoil to the <br />subsoils. In the case of ameliorated subsoils, topsoil shall be placed shortly aft~;r the subsoils <br />have been amended. Loose faces of slopes shall be "walked" with a dozer to partially compact <br />the surfaces prior to placing topsoil. <br />Seedbed prepazation for areas to be revegetated will take place after grading, stabilization, and <br />topsoil placement will include: <br />1. Compacted surfaces will be loosened and left in rough condition by ripping, disking, <br />or other mechanical means. Loose erodible surfaces may need to be "dozer-tracked" <br />to prevent sloughing before amendments, seed, and mulch are applied. <br />2. The soils will be tested at the time of reclamation for fertilizer. If nece:~sary, fertilizer <br />will be applied in the amount and rate specified by the tests. The fertilizer will be <br />evenly spread using a minimum of equipment passes to prevent compaction. <br />3. The prepared surfaces will then be seeded using the mixtures and seeding rates <br />recommended in the following section. Seeding will either be by ran.~eland drill or <br />broadcasting, depending on working area and steepness of slope. <br />4. Hay or other protective mulch will be applied, if necessary, and crirrlped. Erosion <br />control practices and BMP's will be implemented as necessary during on-going <br />reclamation activities. <br />Reclamation activities will occur [o take advantage of optimal climactic conditions. Following <br />are general scheduling procedures to be followed: <br />1. Grading and drainage control establishment and maintenance will be conducted in <br />mid to late summer; <br />N:\DNALLMAN\SANLUIS~SANLUIS.DOC 10-I SRK Project No. 147J2 <br />
