Wood Platform: Applicant should verify whether the existing wood platform shown in the survey is <br />to be removed or is to remain, or is seasonal for winter dock storage. If it is to remain or is <br />seasonal, the applicant should clarify how this impacts the planting plan. <br />2. Shrub Spacing: A number of the proposed shmbs are shown at 6' or 7 ’ on center. This includes the <br />dogwoods, viburnum, amur maple, and sumac. \Nhi\e this spacing reflects their mature size, it does <br />not provide sufficient root structure to stabilize the slope when the roots of the previously cut <br />vegetation decompose. The maximum spacing on new shrubs should be reduced to 4' on center, <br />with 3' on center preferred for smaller species. The honeysuckle at 2.5' on center is appropriately <br />spaced. Applicant should revise plant quantities as required to cover exposed slopes. <br />3. Perennial and Grass Spacing: To stabilize the slope, ali perennials and grasses should be spaced <br />at 1.5* on center, with the exception of the switch grass and little bluestem, which should be spaced <br />2' on center, and the sedum, which should be spaced at 1* on center. Applicant should revise plant <br />quantities as required to cover exposed slopes. <br />4. Plant Species: The Moonshadow and Winter Creeper Euonymous and the Wilton Carpet Juniper <br />are not proven performers for stabilizing south-facing slopes. Ash Leaf Falsespirea and Red or <br />White Snowberry are recommended alternatives. Also, amur maples have begun to show up in the <br />wild and are competing with native plants, so are not recommended. <br />5. Planting Practices/Temporary Erosion Control; Excess soil removed from planting holes will wash <br />into the lake if it is left uncovered on the slope. Therefore, cutting existing dead stumps off at the <br />ground, seeding the slope, placing type 2S straw erosion control blanket, and then planting through <br />the blanket, is recommended. No excess soil should be left on top of the blanket. <br />‘it <br />Bomatroo, Boautt, Andartlk and Aaaoetataa, Ine.WWW, bonestroo. com <br />om.PWkimmutWrnefM <br />aMiMiitii <br />nmmMU <br />01innucaipw*.mum <br />01 <br />lIJMMSiNf <br />.mum mmim <br />OftCMt <br />S73llf ItMift <br />9ICM.MNSU0I <br />OOUeaiK <br />nmne <br />ffdLSit k»
