Maintenance Methods <br /> Bluff Area <br /> In the Bluff buffer area the buffer area will initially have buffer monumentation placed approximately <br /> every 200 feet along buffer edges. <br /> Area B <br /> In buffer area B the buffer area will initially have buffer monumentation placed approximately every 200 <br /> feet along buffer edges. <br /> Area C <br /> In buffer area C the buffer area will initially have buffer monumentation placed approximately every 200 <br /> feet along buffer edges. <br /> Next year vegetative management will occur with spot spraying and weed whipping of areas, followed by <br /> Escort or Glysophosphate application to weed areas needing control. Seed will be spread if necessary per <br /> the below seed specifications if needed. <br /> V. Seeding Specifications if Planted: <br /> a. Timing of Seeding: Due to the small size of most buffer seed varieties, all seed will be broadcast. <br /> To maximize success, the planting of seed can only occur within two small windows, April 1 to <br /> June 30 or September 1 to December 1. <br /> b. Seed Mix and Installation Specifications*: The grassy buffer maintained areas will be seeded <br /> with Mix 35-541 at 12.0 pounds of pure live seed per acre. Cover crops specified for each mix will <br /> be seeded with each mix in accordance with BWSR mix specifications. The Appendix contains the <br /> specifications for the seed mixes specified. Below is a table and summary of seed mixes. <br /> Rate Est. Total Amt. <br /> Seed Mix (lb./ac..)

Site Preparation and Seeding Technique: The upland buffer areas will be dragged after the seed <br /> is broadcast as needed to achieve proper seed to soil contact. Straw mulch will be applied at 1.5 <br /> tons per acre and disk anchored where possible. On any slopes in the buffer area exceeding a 10 <br /> percent slope, straw erosion blanket will be installed after seeding. <br /> VI. Prevention of Introduction of Invasive Species: It is important that any topsoil that is placed on <br /> the site be free of any rhizomes and seed from vegetation that is undesirable in a buffer. Therefore it is <br /> imperative that the coordination between the grading contractor and the environmental consultant is <br />
