Perform temporary seeding promptly at the locations and under any of the following conditions when directed by the Engineer :
that permanent seeding and mulching operations can be performed without subsequent serious disturbance by additional grading;
roadbed where construction operations are temporarily suspended or where the grading of the road bed has been completed substantially in advance of the paving construction;
contract;
on any area. The actual conditions that occur during the construction of the project will determine the quantity of seed or fertilizer to be used. The quantity of seed or fertilizer may be increased, decreased or eliminated entirely as directed by the Engineer . Such variations in quantity will not be considered as alterations in the details of construction or a change in the character of the work. -2 MATERIALS Refer to Division 10. Item Section Fertilizer 1060 -2 Mulch for erosion control 1060 -5 Seed 1060 -4 See the contract for analysis of fertilizer and the kinds of seed. -3 CONSTRUCTION METHODS
Scarify areas to be seeded to a depth of not less than 5 inches unless directed by the Engineer otherwise. The soil conditions and topography will determine the required depth of the seedbed. Prepare the surface to be seeded with adequate furrows, ridges, terraces, trenches or other irregularities in which seeding materials can lodge with reasonable assurance that the materials will not be easily displaced by wind, rain or surface runoff.
The analysis of fertilizer, the kinds of seed and the rates of application of fertilizer and seed shall be as stated in the contract. Apply no fertilizer or seed when the Engineer determines that conditions are unfavorable
