southwest portion of the property and has a total area of 29.73 acres. It is a complex of wetland types that lies within the floodplain of Trott Brook. A series of ditches has been excavated through the area in an attempt to make the land suitable to agriculture. Haying activity appears to still transpire in the area. The fourth basin is along the western property boundary in Section 25 and is a Type 1 wetland. At the time of the delineation the area was denuded of vegetation, apparently as a result of the crop being flooded out. It is identified as west and totals 0.63 acres. The fifth basin is behind the current house. It is identified as Basin north and is a Type 2 wetland totaling 0.39 acres. All of these basins have experienced a diminishment of functions and values as a result of associated land uses. In addition, none of these basins have a buffer area and several of the areas are currently being drained via ditches. The development will require the mitigation of 52,008 square feet of wetland for the purpose of drainage and road improvements, especially the new County Road 40 alignment. The wetland mitigation is more defined later iri the narrative. IV. WETLAND ALTERATION The preliminary grading plans show approximately 52,008 square feet of wetland alteration. However, 38,681 square feet of this total would be impacts to the ditch. These impacts would be largely unavoidable with the proposed reconstruction of County Road 40. These linear ditches are unavoidable with the site development. The proposed storm sewer is replacing the function of the ditches. Another 5,832 square feet of the northeast basin will be impacted for the proposed realignment of County Road 40. The 7,495 square foot balance of alteration occurs in six areas, each relatively small, in the southern portion of the site. No DNR Public Waters will be altered by this development. The plans also show 64,475 square feet of new wetland creation. These are created adjacent to existing wetlands. Several of the existing wetlands have degraded significantly due to land use activities in the area. It is proposed that these basins be hydrologically and vegetatively restored. The preliminary plan indicates approximately 31.4 acres of wetlands, which have been degraded due to adjacent land use, suitable for restoration. V. TREE PRESERVATION A significant portion of the woodland located westerly on the property is of high F:\ENG163300\264\REPORTS\River Park Narrative.426.doc 9
