The list includes a variety of native species and varieties or cultivars of native species of shrubs, grasses and forbs. • The landscape plan does not include a scale, so it is difficult to determine the proposed spacing of the plant material. Inclusion of a scale is a standazd requirement on landscape plans. The plans should be resubmitted, � including a scale so that spacing of plants and adequacy given the site conditions can be determined. This is important given the slopes on the site. • The slopes on the site are relatively steep—including 3:1 and 2.5:1 slope axeas. Given the proximity to the lake, erosion may occur while the plantings are becoming established—particularly if they are widely spaced. � � On the 3:1 slopes,fabric(straw blanket or coconut fiber)or several inches of mulch should be used to stabilize the �„ soil and help to hold moisture. The fabric may be placed on the slope and staked according to the manufacturer's � specifications,and then cut to place the plants. Shredded hardwood mulch should be used rather than woodchips to minimize movement during rain events, if this is selected rather than the fabric. • On the 2.5:1 slopes, fabric should be used to stabilize the soil. This meets MnDOT specs for plantings on slopes. The fabric should be placed with the contours,and staked in place according to the manufacturer's directions. Please call me at(651) 604-4758 if you have questions regarding these comments.
