The major draa.nage ditch, which is located within the central portion of the <br /> property, drains into Peavey Lake and evenivally Lake Minnetonka via ditches,pipes,and culverts. <br /> The applicant is proposing to construct a stormwater pond within the central drainage ditch by <br /> widening and deepeni.ng and installing a weir structure at the southern end to manage water levels <br /> during the yeaz. The drainage ditch of the proposed project exhibits fairly steep sideslopes and a <br /> dominance of non-native, invasive vegetation such as reed canary grass. A 1��IlVR.AM assessment of <br /> the e�sting drainage ditch indicates that the ditch has low to medium wetland functions and values. <br /> - The proposed stormwater pond is the last opportu.nity to treat stormwater prior to reachi.ng Lake <br /> Minnetonka and consequently improve the water quality of Lake Minnetonka and downstream <br /> waters. � <br /> The proposed project involves three separate areas witbi.n the Wayzata Couniry Club golf course. <br /> The proposed impact area is located within the.central portion of the site and involves approxi.mately <br /> 1,1001inear feet of an existing drainage ditch. The wetland mitigation areas are located adjacent to <br /> � existing wetlands on the subject property. Mitigation Basin A is located adjacent to an existing <br /> stormwater pond within the northern portion of the site and includes a 25-foot average upland buffer. <br /> Mitigation Basin A,including the upland buffer, encompasses approximately 0.53 acres of the <br /> subject property. Mitigation Basin B is located adjacent to an existing drainage ditch within the <br /> western portion of the subject property. In addition to a wetland area,the applicant is proposing to <br /> create a 25-foot average upland buffer adjacent to the mitigation basin. Mitigation Basin B, <br /> including the upland buffer, encompasses approximately 1.32 acres of the subject property. <br /> MFRA delineated five wetland basins/drainage ditches in the fa11 of 2008.Minnehaha Creek <br /> Watershed District(MCWD)reviewed the wetland delineation duri.ng multiple site visits and <br /> approved the boundaries as staked in the field.A copy of the wetland delineation report is atta.ched <br /> to this permit application. - <br /> The project includes one wetland 'unpact,which includes approxi.mately 0.55 acres(24,041 SF) of <br /> the project site. The proposed impact is due to the proposed pond construction within the existing <br /> dra.inage ditch. The pond will exhibit water depths of 10 feet in the deepest portion, a fountain, and a <br /> _ rock rip-rap border. The proposed features of the pond result in a wetland impact,which requires <br /> replacement at a 2.25:1 ratio. In addition to the proposed impact,the applicant is responsible to <br /> replace 0.04 acres (1,663 SF) of a wetland area that has already been impacted due to construction <br /> activities that occurred during the 2008 growing season. Because this i.mpact was not permitted,the <br /> applicant is responsible to replace the impact at a 4:1 replacement ratio. The proposed and non- <br /> permitted wetland impacts will be replaced withi.n the golf course. Wetland mitigation will be <br />
