Item 402-PC Agenda- *02/21/2012 <br /> File#11-3531[Total Pages 148] <br /> 1111 <br /> Appendix C <br /> Native Grassland Establishment and Management Plan <br /> For 4550 Wolferton Place <br /> Orono, MN <br /> February 4. 2012 <br /> I.Overview: This project is For the establishment of 189,834 sf of native grassland buffer. The created <br /> buffer will depend primarily upon surface water from adjacent land to establish the necessary hydrology. <br /> 111/ Therefore it is important that the grading is done carefully and planned in accordance with the grading <br /> 10 plan, <br /> i[. General Project Goals: 'l'he primary goal of this project is to create high quality buffer areas that will <br /> greatly exceed the functions and values of the disturbed grassland. One seed mix will he installed at <br /> appropriate locations following the latest standards and guidelines of the BWSR entitled "Guidelines for <br /> Restoring and Managing Native Wetland Vegetation." There may he some variation from these <br /> guidelines where timing and site conditions warrant modification. Five years ofaficrcare are planned to <br /> 1110 control invasive species such as smooth hrome,canada thistle, stinging nettle, and reed canary grass. <br /> III. Specific Buffer Goals: The goal of this project is to establish: <br /> - 189,834 slot'Buller establishment <br /> Below is u summary of the specific areas of restoration a.'shown on the 4550 Wolferton Establishment <br /> Plan Figures: <br /> Buffer Size Size <br /> Area (11.2) (acres) Type <br /> North 10,485 0.24 Buffer <br /> South 179,349 4.12 13uffer <br /> r Total = 189.834 4.36 Buffer <br /> 110 <br /> p <br /> IV, Grading Considerations: <br /> Prior to establishing the contours on the mitigation areas careful removal and sorting of the sod and native <br /> soils must take place to minimize contamination by seed and roots of'invasive species. This grading must <br /> he done while in the presence of the project manager, who preferably is a natural resource scientist or <br /> other qualified individual.
