The addition of the stormwater pond will help in � <br /> treating these contaminants prior to entering downslxeam waters. Because the proposed <br /> stormwater pond benefits the environment and users of downstream waters,the applicant <br /> ' believes the no-build alternative is not a feasible and prudent alternative. . <br /> Alternative Site <br /> . The nature of the project does not justify the use of an alternative site. The proposed project <br /> involves the ponding of stormwater on the applicant's property prior to entering Lake � <br /> Minnetonka and an amenity to the golf course.Although there are other potential locations to <br /> construct a storxnwater pond within the existing drainage ditch downstream,many of those <br /> locations aze either too small to accomplish the proposed project and involve multiple <br /> landowners,which would hamper a,feasible and efficient project. In addition, constructing <br /> t�ie stormwater pond at an alternative location would deny the applicant to construct the <br /> desired am.enity to the existing golf course. T'he proposed project provides wetland mitigation <br /> on-site and a MNR.AM of the proposed mitigation locations indicate that the proposed <br /> mitigation basins will exhibit wetland functions and values that are greater than the e�sting <br /> dra.inage ditch. <br /> Alternative Site Design <br /> ' Although an altemative site design�that avoids wetland impacts is possible,it would not serve <br /> ' the purpose of the proposed project. The applicant could construct a stormwater pond <br /> adjacent to the existing drainage ditch,however this may effect the current hydrology of the <br /> existing drainage ditch,interfere with the existi.ng fairways, and not be a sensible design. The <br /> . preferred site plan utilizes the existing grades to capture and treat stormwater that flows from <br /> . the fairways located north of the Luce Line Sta.te Trail. Placing the proposed stormwater <br /> pond outside of the existing drainage ditch would not provide the treatment of stormwater <br /> • from the northern portion of the subject property and negate the purpose of the project.• <br /> The applicant has demonstrated that the wetland functions and values of the existi.ng drainage <br /> ditch/Wetland 1 are low to medium. The applicant has identified two locations within the � <br /> golf course where wetland mitigation could be provided in place of the proposed impacts. <br /> Based on the 1��Il�1RAM,these mitigation basins will exhibit wetland functions and values of <br /> greater quality than the e�sting drainage ditch. <br /> Impact Minimization <br /> The project site has been designed to minimize the amount of wetland impacts while meeting <br /> the project purpose. Approximately 0.59 acre(25,704 SF) of wetland will be impacted as the <br />
