to native trees, shrubs, and ferns. Nonnative shrubs will be removed along the fenceline. <br /> Bulrush will be retained where present in and along the channel. <br /> Native vegetation will be planted within the approximately 5,660 square feet of retained buffer so <br /> that overtime, it will function with increased vegetative diversity, structure, and stream bank/slope <br /> stability. Native plantings will provide infiltration and filtration of overland flow and reduce use <br /> on lawn chemicals near the stream. Overtime,planting shrubs and trees in this area would <br /> improve stream habitat conditions through shading and reduction of nonnative plants (lawn <br /> grasses, buttercup, and ornamentals). Habitat components for some species such as birds will be <br /> improved. The small size of the planting area combined with the dense residential development in <br /> the area limits improvement to habitat associated with the buffer enhancement planting. Planting <br /> specifics are provided below in the Planting Plan. <br /> H . f:1',-,17/;IP, . <br /> '^ v' � <br /> �y +z <br /> ' ��,,,y '. . . ,-`10.:'V..-.

Where materials were removed,the channel will be restored and <br /> enhanced. <br /> The large rock will not be replaced to line the channel walls. Some of the large rocks will be <br /> used within the stream channel to provide a series of"cascade"feature designed to reduce <br /> velocity and capture silt during high flows. Vegetative plantings will provide bank stabilization <br /> and reduce siltation to the channel. Plant species are discussed in the Planting Plan below. <br /> At the edge of the existing driveway,the retention walls are constructed with what appears to be <br /> creosote treated lumber. On the property,the treated timbers will be replaced with natural <br /> materials such as stone. <br /> Fencing will be built along the south property line within buffer. The fencing will be truncated to <br /> allow an approximately 20 feet opening for the stream channel. <br /> 4 <br />
