These structures are generally proposed to be installed above the OHW and <br />100-year flood elevation. No impacts are therefore expected within these public waters. <br />The proposed stormwater outfall to the Mississippi River could impact the river bluff <br />zone through alteration of shoreline vegetation, increased susceptibility to erosion, <br />aesthetic views and water quality impacts (discussed in Item 17). <br />Mitigation element. <br />Wetland Sequencing - Minnesota Rules 8420, also known as the Wetland Conservation <br />Act (WCA), requires specific steps (—sequencing") be taken when evaluating mitigation <br />for unavoidable wetland impacts. The WCA requires that wetland impacts be avoided, if <br />possible. If wetland avoidance cannot be accomplished, impacts to wetlands need to be <br />minimized. Finally, any wetland impacts that can not either be avoided or minimized to <br />the extent possible, must be mitigated though wetland replacement. The wetland <br />replacement must mitigate all wetland functions and values lost as part of the wetland <br />impact. <br />The degradation present on site allows the applicant to evaluate sequencing flexibility in <br />their mitigation plan. It also allows the Technical Evaluation Panel (TEP) the <br />opportunity to be flexible on the sequencing provisions of the WCA rule. This process <br />may only be applied in the event the wetlands on -site are degraded to the point where <br />replacement of the wetland would result in a gain in functions and values. This is an item <br />that will be considered by the TEP during the permitting process. <br />Wetlands located on site are described in the Wetland Delineation Report (Appendix A), <br />and are discussed in Item 10. With a few exceptions, wetlands located within the <br />boundaries of the RTC are either cropped or are of low quality. These wetlands have <br />12-5 <br />
