Existing vegetation within the desib ated wetland buffer on the site has a continuous dense layer <br /> of perennial grasses that have been unbroken for at least 10 consecutive years. Buffer adjacent to <br /> Wetland 1 should not be disturbed by construction activities. Buffer augmentation or vegetative <br /> restoration within the buffer i"s not proposed as this type of physical disturbance often increases <br /> the amount of invasive/noxious weeds in this location and throughout the site. The on-site <br /> wetland and adjacent buffer must be protected under an easement. <br /> Steeply sloping soils in the northeast portion of the property should be place under conservation <br /> easement to protect them from potential vegetation alteration (conversion to lawn) and erosion. <br /> Sec 78-1635 Basic Conservation Desi�n Master Plan requirements and evaluation criteria <br /> As stated in the code—"The developer sl�all prepare a Conservation Design Master Plan for <br /> development of the property, consisting of written and visual documentation including maps in <br /> an acceptable electronic format, addressing the following topics: <br /> (1) Consideration of the existing drainage system; <br /> Pre and post development topoDraphy is not significantly different; therefore, surface <br /> runoff on and from the site will not sigr►ificantly change. <br /> (2) Establishment of a stormwater management system, using multi-cell treatment <br /> principles,and defining proposed methods of stormwater phosphorus reduction; <br /> Oi�e stonnwater pond to treat inlpervious surface runoff is proposed. <br /> (3) Removal of invasive species and diseased trees; <br /> That majority of invasive species (i.e. common bucl:thorn) and diseased trees (i.e. <br /> diseased American elm) are only present in t11e southeast portion of the site (Figure 7 <br /> KCS Natural Resources Inventory — Bayside Meadows (W1chm�n Parcel), Orono, <br /> MN). Removal of i��vasive species in the southeast portion of the site will be <br /> accomplished by the landowner that purchases that lot. M�ny diseased/dying/invasive <br /> t�ees will likely be removed with tl�e construction of the home—as that is where many <br /> of those trees are located. 'I'he methods for common buckthorn removal were included <br /> in Appendix � of the previous subinitted KCS memo. Common bucl:thorn located. <br /> within the north portion of the site will be removed for roadway consiruction. Trace <br /> amounts of common invasive/noaious weeds are present in the east third of the site and <br /> include: garlic mustard, Canada thistle, mothei-wort, and common burdocic. <br /> (4) Protection of significant tree stands and woodlands that support scenic and/or <br /> ecological goals, including mitigation of any such stands to be impacted by <br /> development activities. <br /> The very southeast corner of the site contains a sib ificant tree stand, of which a portion <br /> would be beneficial to preserve. Only that portian of the tree stand that does not <br /> include invasive common bucl:thorn and diseased elms should be preserved (area <br /> outside of the identifed Diseased Tree area shown on Fi�ure 7 of the previous <br />
