The site was located <br />in Section 6, Township 28N, Range 20W, City of Afton, Washington County, Minnesota. <br />Generally, the site was located south of Interstate 94 and east of Neal Avenue South. The site <br />boundaries corresponded to Washington County PID: 0602820410002 (Figure 1). <br />The 40.76-acre site was comprised of open fields, wetlands, existing structures, and <br />approximately 22.36 acres of trees grouped into three large continuous areas of planted <br />woodland. The purpose of this memo is to explain the tree survey results. The woodland was <br />divided into two tree areas, Tree Area 1 ('17.25-ac) and Tree Area 2 (5.17-ac), based on aerial <br />canopy similarities. The division of the woodland into similar canopy groupings allowed the <br />subsampling method to more accurately projected tree Basal Area (BA) for each grouping. For <br />the proposed survey methods see attached Tree Survey Methods Memo in Appendix A. <br />Tree Survey Results Overview <br />• 22.36 acres of woodland onsite. <br />• All significant trees impacted by primary and secondary construction zones were sampled <br />(Figure 2A-2F).

Data located in Appendix B. <br />• The site had a sampled diversity of 24 different species, of which —91 % of the trees <br />sampled were either red pine, white pine, or white spruce (Table 1, on following page). <br />• Sample plots projected a site total tree BA of 3790.78 sqft (Table 2, on the following <br />page) and the total tree BA impacted equaled 889.66 sqft, or 23.47% of total projected <br />BA on -site. <br />2500 Shadywood Road, Suite 130, Orono, MN Phone: 952-401-8757 <br />
