If not incorporated <br /> during the soil preparation process,add pH modifier and fertilizers at the <br /> rate specified in the soil test report. <br /> • Re-compact the area utilizing a cultipacker roller.The finished grade shall <br /> be a smooth even soil surface with a loose, uniformly fine texture. All <br /> ridges and depressions shall be removed and filled to provide the approved <br /> surface drainage. Seeding of graded areas is to be done immediately after <br /> finished grades are obtained and seedbed preparation is completed. <br /> Areas to be Sprigged,Sodded,and/or Planted: <br /> • At the time of planting till or disc the prepared areas to a depth of four(4) <br /> to six(6) inches below the approved finished grade. Remove all stones <br /> larger than three(3)inches on any side,sticks,roots and other extraneous <br /> materials that surface. If not incorporated in the ripping process,add pH <br /> modifier,fertilizer,and other recommended soil amendments. <br /> • Re-compact the area utilizing a cultipacker roller and prepare final grades <br /> as described above. Install sprigs,sod and plants as directed immediately <br /> after fine grading is complete. Mulch,mat and/or tack as specified. <br /> VEGETATION <br /> Availability of seed and plant materials is an important consideration of <br /> any construction stabilization effort. Throughout North Carolina, climate, <br /> economics, construction schedule delays and accelerations, and other factors <br /> present difficult challenges in specifying the different vegetation needed for <br /> site stabilization. To help resolve this issue,vegetative stabilization requires <br /> consideration in three categories: <br /> ■ Immediate Stabilization—nurse crop varieties(Note: temporary mulching <br /> may be utilized for immediate stabilization if outlined on the approved <br /> plans and construction sequence.) <br /> ■ Primary Stabilization—plant varieties providing cover up to 3 years with <br /> a specified maintenance program <br /> ■ Long Term Stabilization—plant varieties providing protective cover with <br /> maintenance levels selected by the owner <br /> An adequate job in one of these areas does not guarantee success in the later <br /> phases. Horticultural maintenance must be included in the plans. <br /> Immediate vegetative cover will always require additional fertilization, soil <br /> amendments, soil tests, overseeding and/or other horticultural maintenance <br /> until primary vegetative cover is established. <br /> 6.11.4 Rev.5/08 <br />
