to have formed due to excavation that has occurred for a ditch. Future submittals should reflect <br /> the buffer and setback without this finger of wetland. Any proposed fill in this finger of <br /> wetland may still require a permit from the Watershed District. <br /> A site evaluation of wetland#2's buffer was also conducted on September 4,2007 to determine <br /> the condition of the vegetation in the existing upland buffer. Common buckthorn was again <br /> found to be a dominate species in wetland#2's buffer. As is stated above buckthorn is <br /> considered to be an undesirable plant species and should be removed from the upland buffer <br /> area. After buckthorn is removed,bare or disturbed areas in the understory should be seeded <br /> with a shade tolerant,approved native seed mix(see general comments below). <br /> General Comments: <br /> A management/landscape plan to remove the buckthorn and reseed or plant the bare areas as <br /> well as the turf area within the buffer should be provided. At a minimum it should include <br /> species to be seeded or planted and method,method of removal of buckthorn and schedule of <br /> activities. <br /> According to the ordinance Div.3 Sec.78-1605(3)the seed mix must contain at least 12 pounds <br /> (PLS)per acre of native prairie grass seed and 5 pounds(PLS)per acre of native wildflower seed. <br /> The grass mixture must contain a minimum of four species while the wildflower mixture must <br /> contain a minimum of five species. The seed mix used must be submitted to the city prior to <br /> planting for approval. Planting of native species is also an option to substitute for seed but <br /> planting should be space no more then 3-feet apart. <br /> Silt fences should be placed upslope of both wetlands upland buffers prior to construction. <br /> These fences should stay in place until all construction activities have been completed. Silt <br /> fences will make the upland buffer boundaries more obvious and help protect the wetland from <br /> moving sediment during construction. <br /> We recommend that the city take an escrow in the amount of$3,000 to ensure buckthorn and <br /> turfwithin the buffer are removed,bare areas are seeded,and for future compliance checks. <br /> Page 2 ovL <br />
