Spring Hill Golf Club Wetland Replacement Plan Application ' Revised December 5, 2012 Page 2of8 ' with GES and Spring Hill staff in the fall of 2011. GES extended the wetland delineation on the rest of the basin based on the observations and documentation reviewed by the Watershed District and reported in the ' delineation report attached in Appendix A. PROJECT NEED AND PURPOSE The purpose of the project is to improve playability and safety of the golf course in the vicinity of the 13th hole. ' The need for the project involves creating landing areas for golf shots that commonly land at the two locations where fill is proposed in the wetland. These issues are addressed in greater detail in the "Sequencing" section below. ' CUMULATIVE IMPACTS The original project resulted in a total wetland fill of 1.45 acres for which 7.27 acres of wetland mitigation credit were provided. The impacts now proposed would add 0.42 (18,249 square feet) additional acres of wetland fill (about one-third the amount of wetland originally filled). The proposed ' project is not intended as a "piecemeal" impact to the wetland; in retrospect, the proposed fill should have been a part of the original permit application and approvals in the late 1990's. PROPOSED WETLAND IMPACTS The proposed fill areas would result in a total wetland impact of 0.42 acres consisting of 0.30 acre (12,950 square feet) in the northern fill area and 0.12 acre (5,299 square feet) in the southern fill area (see Figures 3, 4 and 5). The wetland areas to be impacted are primarily Type 3 inland shallow fresh marsh dominated by narrow-leaved and hybrid cattail. Both wetland impact areas are above the Ordinary High Water (OHW) elevation ' so the impacts are not regulated by the DNR protected waters program. Both fill areas also have an insignificant quantity of fringe Type 2 inland fresh meadow wetland dominated by reed canary grass. All of the ' wetland impacts are considered to be in Type 3 wetlands. ' The project proposed would require approximately 2,200 cubic yards of fill material for the north fill area and approximately 2,500 cubic yards for the south fill area. In the north fill area, a 24-inch diameter pipe would be ' installed beneath the fill in order to maintain the normal hydrologic connection within the wetland. This north fill area will divide the wetland into two areas, west and east. The east wetland area will be connected to the west wetland area via the aforementioned 24-inch diameter pipe. This
