Existing vegetation within the designated wetland buffer on the site has a continuous dense layer of perennial grasses that have been unbroken for at least l O consecutive years. Buffer adjacent to Wetland I should not be disturbed by construction activities. Buffer augmentation or vegetative restoration within the buffer is not proposed as this type of physical disturbance often increases the amount of invasive/noxious weeds in this location and throughout the site. The on-site wetland and adjacent buffer must be protected under an easement. Steeply sloping soils in the northeast p011ion of the property should be place under conservation easement to protect them from potential vegetation alteration (conversion to lawn) and erosion.
