Applicants must adequately explain and justify each individual contiguous wetland alteration area in terms of impact avoidance and minimization alternatives considered. To be eligible for New Wetland Credit (NWC), replacement wetland adjacent to upland must include upland buffer of native vegetation at least 25 feet in width adjacent to the entire NWC area except where contiguous with existing wetland. The buffer must meet WCA requirements for Public Value Credit (PVC). Replacement wetland must be designed to replicate at least 50 percent of each wetland community type (as defined in MnRAM 3.0 or subsequent revisions) being altered. Where the wetland alteration is proposed in the context of land subdivision, on- site replacement wetland cannot be located on a buildable lot and must be separated from buildable lots by a physical barrier such as a stormwater pond, infiltration basin, existing wetland or other permanent physical feature that protects against future encroachment into the replacement wetland. e) The upland edge of new wetland creation must have an irregular apd uneven slope The slope must be no steeper than 8:1 over the initial 25 feet upslope from the projected wetland elevation contour along at least 50 percent of the upland /wetland boundary and no steeper than 51 along the remaining 50 percent of the boundary. f) The District will not allow excess credits to be used for replacement on a different project unless the credits were designated for wetland banking purposes in the original application in accordance with WCA rules and have been deposited into the WCA wetland banking system The District may permit otherwise- conforming credits pot yet deposited into the wetland banking system to be so used if construction was completed within two nears of submittal of a complete application 20�osing to use them and on District consideration of the recommendation of the Technical Evaluation Panel. f, REQUIRED EXHIBITS.
