Along with this, the Council also assumed the role of local government unit (LGU) for making WCA determinations for landowners. The purpose of WCA is as follows: 1, Achieve a no net loss in the quantity, quality, and biological diversity of Minnesota's existing wetlands; 2. Increase the quantity, quality, and biological diversity of Minnesota's wetlands by restoring or enhancing diminished or drained wetlands; 3. Avoid direct or indirect impacts from activities that destroy or diminish the quantity, quality, and biological diversity of wetlands; and 4. Replace wetland values where avoidance of activity is not feasible or prudent. Current Circumstances As part of the Mystic Lake Golf Course conditional use permit, the SMSC (Shakopee Mdewakanton Sioux Community) has requested approval of a wetland replacement plan for the project. The reason a replacement plan is required is that to reshape, fill, and/or move existing water hazards and wet fairways, These water hazards and wetland fairways have steep slopes, minimal vegetation, or are maintained fairway areas. As such these areas provide minimal wetland function and value. The final design calls for 6.8 acres of existing wetland impacts. Mitigation is proposed through the following combination: . 1.45 acres of new wetland credit (NWC) from a wetland banking site that is held by the SMSC and is within the same major watershed as required by WCA. . 5.35 acres of NWC from an off-site restoration that is located within the same major watershed. 162eQAgeOOit\\l;_~~ci.JOOcLake, Minnesota 55372-1714 / Ph.

Memorandum To: Sue McDermott, P.E., City of Prior Lake From: Andi Moffatt, Biologist John Mackiewicz, Water Resource Specialist Date: August 27, 2003 Re: Mystic Lake Golf Course Water Resources Plan Review WSB Project No. 1430-36 As requested, we have reviewed the Mystic Lake Golfplans and Wetland Replacement Application dated August 8, 2003, Our review covered the areas ofthe Golf Course within the Fee Land. The portion of the project that is on the Trust Land was not reviewed as local and State rules do not apply to this area, Based on the review, we offer the following comments: Wetland Conservation Act Review Attached, please find the draft Notice of Wetland Conservation Act Decision and Wetland Conservation Act Determination Findings and Conclusions for the Mystic Lake Golf Course project for City Council consideration at their upcoming meeting, Outlined below, please find our review and summary of the Wetland Replacement Plan: 1. The Wetland Replacement Plan application was received from the applicant on August 8, 2003, The application was initially determined to be incomplete with the additional information required being provided on August 26, 2003, The application was submitted for a 30-day agency comment period, The 30-day comment period ended on September 29, 2003, The wetland delineation was field checked by WSB in May 2002, 2. The Mystic Lake Golf Course project includes a total of6,8 acres of wetland impact, Of this amount, 3.43 acres of wetland impact is subject to the Wetland Conservation Act. 3. This impact is primarily in the form of reshaping, filling, and/or moving existing water hazards and wet fairways, Theses water hazard and wetland fairways have steep slopes, minimal vegetation, or are maintained fairways areas, As such, these areas provide minimal wetland function and value, 4. Mitigation is proposed through the following combination: . 1.45 acres ofNWC from a wetland banking site, This is Bank Account #1090 that is held by the Mdewakanton Sioux Community. . 5,35- acres ofNWC from an off-site restoration . 4.46 acres of on-site Public Value Credit from the creation of water hazards, Stormwater will not be directed to these water hazards. September 29, 2003 Page 2 of2 5. Both the wetland impact, banking site, and off-site restoration are within the Minnesota River-Shakopee (#33) major watershed, The Wetland Conservation Act (WCA) requires that wetland replacement be on-site if possible. If this is not possible, the replacement site needs to be in the same major watershed as the impacted wetland, Some on-site replacement is proposed for this project, The remaining mitigation is within the same watershed as the impacted site (Minnesota River-Shakopee),\ We recommend that the Replacement Plan Application be approved. The attached documents have been provided to you for review as part of the Mystic Lake Golf Course review and approval. Once the Council has approved the wetland replacement plan, these documents will be sent to the appropriate agencies for their information and processing. Hvdrolol!icIHvdraulic.

This area is outside of the city's jurisdiction but because of the areas proximity to the Eagle Creek Sub Station the water should be treated prior to discharging into the protected wetland, This issue has been discussed with the project engineer and it is anticipated that this will be changed on the next plan. 6. The emergency overflow from pond GC12 should be illustrated on the plan, This issue has been discussed with the project engineer and it is anticipated that this will be changed on the next plan, If you have any questions, please feel free to call us at (763) 541-4800. c, Dave Hutton, P,E., WSB /....~iir'.~ /oy".J!.t" I~r '\.(\ f:::f \~'\ (U(~~ \f,~s~...;J Wetland Conservation Aet Notice LGU : City of Prior Lake 16200 Eagle Creek Avenue SE Prior Lake, MN 55372-1714 WETLAND CONSERV A nON ACT DETERMINA nON FINDINGS AND CONCLUSIONS Name of Applicant: William Rudnicki.
