Appendix A Buffer Establishment and Management Plan For 3245 Wayzata Boulevard 'Nest Orono, MN April 30, 2016 IL Overview: This project is for the establishment of several bluff buffer areas and for Area A., Area B, and Area C as shown in they attached plan to effectively buffer adjacent wetlands as shov,m on the attached Figure 7 Site Detail Conservation Plan and the Figure 8 Top of B1ufl'Buffe:r plan. The maintained buffers will depend primarily upon surface water from adjacent land to maintain the necessary hydrology, I1. General Project Goals: The primary goal of this project is to maintain buffer areas that will ]')reserve and enhance the functions and values of the current buffer. An ongoing buffer maintenance plan ,viilll be employed in this case. There may be some variation from these guidelines where timinh2 and site conditions warrant modification. Five years of aftercare are planned to control invasive species such as canada thistle, stinging nettle, garlic mustard, bull thistle, purple loo sestrife, common buckthorn, and spotted knapweed in the buffer or managed. areas. III. Specific Buffer Type Goals: The goal of this project is to maintain or establish the follo)h,ing: Grassed bluff buffers as shown -on the attached Figure 8 from the 986 contour or the black :line to the tree line which is to the west, south, or east of the black: line to the tree edge which is principally box elder (Acer negundo). Common Buckthorn (Rhamnus cathar•tica) of over 1" dbh cut off at the ground in Area lB as shown in Figure. 7 and stumps sprayed with glysophosphate as recommended in the Al-Tendix. A native grass buffer established in Area C on Figure 7. Below is a summary of the specific areas of buffer maintenance as shown on. the Centum% Farm VVMC Declaration Plan: Buffer Size Size Area (ft.2) (acres) Buffer Type Bluff TBD TBD Preserved Grassed Buffer of 30 -- 50 feet on the south B TBD TBD Preserved Wooded Buffer, Buckthorn Controlled C TBD TBD Preserved Grassed Bufter Total = TBD TBD W. Planting Considerations if' areas are disturbed and not: ,just rnaintained: Prior to establishing the contours on the buffer areas careful removal and sorting of the sod and native soils must take place to minimize contamination by seed and roots of invasive species.
