Whenever slope areas to be topsoiled are steeper than 3:1 these slopes shall be disked or scarified to the depths indicated on the plans prior to placing topsoil. After the Engineer has approved the graded areas, topsoil shall be spread to a depth which, after settlement, will provide the nominal depth shown on the plans. Spreading shall not be done when the ground or topsoil is frozen, excessively wet, or otherwise in a condition detrimental to the work. The roadway surfaces shall be kept clean during hauling and spreading operations. After spreading has been completed, large clods, stones larger than 2 inches (50.8 mm) and any roots, stumps, and other litter shall be raked up and removed and disposed of at an approved location. Method of Measurement 624.05 The quantities to be paid for will be the number of cubic yards of topsoil complete in place and accepted.

(a) Soil preparation.-All areas to be seeded shall be cultivated to provide a reasonably firm, but friable seedbed. Depth of cultivation shall be as shown on the plans unless otherwise directed by the Engineer. On slopes steeper than 3.1, depth of cultivation may be reduced as directed. All areas to be seeded shall meet the specified finish grades, be free of any weed or plant growth, stones of at least two inches (50.8 mm) in diameter or larger, or other debris. Limestone, if required, shall be applied uniformly either prior to or during soil preparation, and shall be incorporated into the soil surface to the depth shown on the plans.
