is located on the SE corner of the project, and bisects the SE area Natural Resources Conservation Area. The buffering requirements for wetland preservation corridor apply to the wetlands on the site in this area. A 50 foot buffer is required around all wetlands in the corridor. A conservation easement must be placed over the wetlands and buffer; and signage identifying the location of the buffer location along all property lines must be installed. An educational brochure should be developed to give to property owners along all conservation easement properties describing the conservation area and what can, and cannot be done in the easement. The developer is proposing (detail sheet 19) to perform restoration work in the wetlands by removing 18 inches of wetland soil. It is doubtful that the Rice Creek Watershed District would allow this and Lino Lakes Environmental recommends against this action. The corps of Engineers considers this an impact. The seed banks in our wetlands are viable and cannot be purchased in a store. Removing reed canary grass is best done by removing the thatch layer (shoots and stems that have laid down over the wetland soil layer over time) and then starting a program to control reed canary regeneration. This can be done with chemicals and/or burning. There is an incidental Wetland in the center of the project. An incidental wetland is an area excavated where there was no wetland and now is functioning as a wetland. The Corps of Engineers does not differentiate incidental wetlands. • The road proposed on the south side of the development that dead -ends under a "future road" scenario should be relocated so that it does not run into a wetland. • Alternative Urban Areawide Review (AUAR) The proposed development exceeds the mandatory threshold for preparation of an EAW; however, the City completed an Alternative Urban Area -wide Review (AUAR) of the I -I- 35 W in 2005. Because of this, the site is subject to the AUAR mitigation plan, and no additional Environmental Assessment Worksheet (EAW) is required. Tree Preservation and New Tree Requirements The Developer Submitted a Tree Inventory with tree removals indicated. The plan must be revised in accordance to Section 3, Sub.4.Q.10 -Tree Preservation and Mitigation Standards which requires identification of `Environmentally Sensitive Areas" and "Basic Use Areas ". Surface Water Management Surface water from this site flows to Clearwater Creek. Clearwater Creek is in the Rice Creek Watershed District. Rule C of the Rice Creek Watershed District Rules, went into effect on July 1, 2013. The rule sets standards to:
