Rules 8420.0520 Subp. 7a) for the wetland impacts proposed as part of improvements to the 13�' hole at Spring Hill Golf Club. Specifically, we have completed MnRAM analyses for the entire wetland complex on the site (referenced as Wetland 15 in old permit documents), the proposed north impact site, the proposed south impact site, and the proposed on-site mitigation wetland. The consultant for the wetland bank proposed to be used for the remaining mitigation requirement has completed a MnRAM analysis for the wetland bank. Based upon the MCWD's policy of desiring wetland mitigation within the watershed district, Spring Hill has proposed to provide what mitigation it can on the site which would be adjacent to the proposed south wetland fill area. Space within the golf course is limited and, as this would be a wetland "creation", only up to seventy-five percent of the new wetland area on the site would be eligible for wetland credit and the required finrenty-five foot average upland buffer(per WCA) would likely qualify for up to twenty- five percent credit. For these reasons, Spring Hill proposes to purchase approximately one-half of the required mitigation credit from a wetland bank (see below). Revised Wetland Imqact Since our June 4 meeting, Spring Hill has modified its plans which would reduce the amount of proposed wetland impact in both the north and south fill areas. In the north fill area, the proposed earthen bridge has been deleted from the plan and the existing span bridge will be reconstructed or replaced to address the maintenance and safety issues discussed in GES, Inc.'s March 30, 2012 Sequencing Application document. Based on preliminary grading plans, the north wetland fill area would cover 15,568 square feet (0.36 acres) as opposed to the 20,600 square feet (0.47 acres) originally proposed. . . .
