• 7. Remove spoil piles when possible without damaging trees or existing natural plant communities. 8. Remove trash when encountered. II. Specific Approach and Strategy Areas proposed for similar treatment are grouped for this discussion. The area numbers refer to those indicated on the attached plan. A. Reve2etate With Wet or Mesic Prairie Seed Mixture. General activities within these areas will include removal (via chemical and mechanical treatment) of existing weedy communities, seeding of appropriate native prairie seed mixture, and short and long -term management. Management activities may include spot chemical treatment, mowing, and burning. Areas between lots and the trail will be seeded with a short - growing native prairie seed mixture to provide a suitable transition. This treatment will be used for areas A2, A3. A4, A5, A7, A8, All, B3, B6_ C2, DI, E6 Acreage proposed for this treatment is 10 acres. Costs are estimated to be $1250. per acre. Total cost for areas receiving this treatment is approximately $12,500. Revegetation activities will begin in April 2000. Seeding will be completed in June 2000. Management activities associated with the establishment of the community will be completed in 2003. The long -term viability of these areas is expected to be good, with low to moderate on- going maintenance requirements. B. Reve etate Storm Water Ponds with Wet or Mesic Prairie Seed Mixture General activities will include preparation of a suitable soil surface, seeding of an appropriate native prairie seed mixture, and short and long -term management. A wet mixture will be seeded near the NWL and a mesic mixture will be seeded throughout the remainder of the graded areas. This treatment is proposed for areas Al, A6, A9, B2, E3, and E5. Acreage proposed for this treatment is 3.5 acres. Costs are estimated to be S1250. per acre.
