Minnehaha Creek Watershed District Response <br />WETLAND IMPACT <br />Comment: “It is not clear on page 6 of the EAW what wetland acreage will be filled. <br />One section of the text states that 1.41 acres are proposed to be. filed. A 2:1 mitigation in <br />combination with the existing 23.6 acres would yield 25.01 acres of wetland after <br />mitigation, yet the text states 24.6 acres will be present after mitigation, “(letter April 9, <br />1997, page 1) <br />Response: The golf course is proposing to fill 1.41 acres of wetland. The proposed mitigation <br />ratio is actually 5.01:1. The break down is as follows: <br />Upland Buffer: <br />NURP Credits: <br />PVC Credits: <br />Created Wetlands: <br />Total: <br />0.64 ac. <br />0.61 ac. <br />3.51 ac. <br />2.51 ac. <br />7.27 ac. <br />Comment: “The Minnehaha Creek Watershed District (MCWD) is the LGU for wetlands <br />located in Orono; projects impacting these wetlands must comply withe MCWD rules <br />and will require a permit from the MCWD. Once the design has been finalized, the <br />MCWD will review the design and accompanying materials to determine if it meets the <br />District’s rules before issuing a permit.” (letter April 9, 1997) <br />Response: A complete set of grading plans, as well as the wetland permit application, has been <br />submitted to the MCWD. <br />STORMWATER TREATMENT <br />Comment: “Treatment of stormwater runoff from the project will be treated by three <br />NURP ponds to be constructed o,i site. The depth of the ponds constructed by wetland <br />excavation will affect the amount of wetland mitigation required.” (letter April 9, 1997) <br />Response: Wetland excavation area has been included in the mitigation. <br />Comment: “There was some indication that one of the ponds will be used as a holding <br />area for irrigation water and will be refilled by pumping from a nearby well. The proper <br />functioning of the treatment pond will depend in part on the withdrawal and refill rates. <br />When the design is finalized, the MCWD will review the project for compliance with <br />MCWD rules and BMP before issuing a permit.” (letter April 9, 1997) <br />Response: The irrigation system w'ill use BMP’s and will comply with MCWD rules. <br />t
