Originally, Wetland I on the site was given a protection classification of Preserve by the Minnehaha Creek Watershed District (MCWD) inventory. In January 2013 KES completed a MNRAM functional analysis for Wetland 1. Based on the analysis results, a revised protection classification of Manage 2 was determined. MCWD approved the management classification change on January 17 , 2013 (Appendix D). Minnehaha Creek Water District (MCWD) revised their Wetland Protection Rule in September 2010. Similar to City of Orono rules, buffers widths are based on the management class of the wetland as determined by a functional analysis. However, MCWD base buffer widths are generally wider than City designated widths. The more restrictive of the widths must be represented on the grading plan. Wetland Buffer Protection, Augmentation, and Enhancement -Existing wetland buffers on the site have a continuous dense layer of perennial grasses that have been unbroken for at least I 0 consecutive years. Buffer adjacent to Wetland 1 will not be disturbed by construction activities; therefore, no buffer augmentation or enhancement is needed. Ecological Management Category Review -The site was assessed for City of Orono Ecological Management Category (EMC) ratings (City Code Sec. 78-1635(9)( 4)), and Figure 6 illustrates observed category areas. Level I EMC areas are associated with wetlands and their buffers. Level 3 E M C areas are suitable for stormwater manage ment. No Level 2 E MC areas (ecological opportunity areas) were observed on the s ite. Invasive Species and Diseased Tree Removal Plan Invasive Species Removal and Management Plan -Areas with invas ive species observed on the site are illustrated in Figure 7. The primary invasive s pecies identified on the s ite was common buckthorn. A detailed common buckthorn management plan is included in Appendix E. Trace amounts of other non-native, invas ive species were observed (common mullein, motherwot1 , garlic mustard). Future seeding of inva s ive s pecies management areas (outside of the graded home lots) is not anticipated because cut stump treatment and foliar spray ing of buckthorn and other trace invas ive s pecies should not result in bare soil or un-vegetated areas. As invas ive species comprise le ss a nd le ss cover over time, native species are 'released'. Native species that have been dormant under the canopy of invas ives are expected to naturall y come back on their own. Although not preci se ly measured , buckthorn trees observed on the s ite represented approximately 99% of the total invasive cover. Buckthorn shrubs less than 1.5 inches in diameter will likel y b e foliar treated. Buckthorn trees greater than 1.5 inches in diameter should be stump cut, and their trunks and branches should be chipped or hauled off the s ite. Diseased and Dying Tree Removal Plan -Tree ID number, diameter breast hei g ht (DBH), and species and for all trees tagged during the field tree survey are induced in Appendix C.
