5. Seed from mid- August thru mid- September after finish grading is complete. Either drill the seed or drag or light disc the soil to prepare a nice, fine, unpacked seed bed. Then broadcast on the seed mix and fertilizer. Light drag the soil once to promote good seed to soil contact and helps incorporate the seed into the soil. Apply straw on the dike with a straw blower or by hand.

The contractor is encouraged to utilize tracked-machines and/or low-ground-pressure equipment to minimize rutting on existing travel-ways and embankments. All ruts resulting from the completion of this project shall be backfilled, compacted, and seeded with an approved seed mix.
