For these reasons, drainage effects to Wetland 4 from Pond 200 construction are not expected to occur. • The current and proposed ditch crossing culvert invert elevations and size are equal pre and post development. Therefore, drainage effects to upstream wetlands are not expected to occur. Per Kjolhaug Environmental Services Appli cant is submitting a geotechnical report addressing the existing wetland & soil conditions and present any proposals to protect the adjacent wetlands as needed. See attached Wetland permit application. Geotechnical report to be submitted when received. 4.A review of the DNR’s Natural Heritage Information System (NHIS) Database revealed that rare fea tures have been recorded in or near the wetlands on the property. In 2002, toothcup (Rotala ramosior), a state threatened species, was located within one wetland that is proposed to be filled. Autumn fimbry (Fimbristylis autumnalis) and Blanding’s turtle (Emydoidea blandingii) have also been recorded near the project site. The developer will need to coordinate with the DNR to obt ain a permit for the take (destroy, dig up, dispose of, possess, or transport) of threatened or endangered species. MnRAM guidance and the 2017 Native Plant Communities Assessment Final Report prepared by CCE S have been reviewed. Based on this review and for WCA/RCWD purposes, vegetation quality for all wetlands onsite was determined to be low, with an associated RCWD wetland degradation status of marginally to severely degraded. Specifically: (1) rare plants found onsite are not persistent and therefore item i of the special features tab in MnRAM does not apply and vegetation quality is Low, and (2) although the Native Plant Communities Assessment Final Report identified rare species onsite, the report also states that (paraphrasing) “these rare species were located within areas dominated by crops or agricultural weeds. While state-listed species do occur within cropland and farmed wetland areas, their presence alone is not enough to classify these areas as native plant communities or rare native plant communities.” Rare plants were primarily found in disturbed, annually farmed wetland fringe areas. Per Kjolhaug Environmental Services. 5.The ghost plat shown in Outlot B on the north end of the project (Sheet 10) appears to propose future wetland impacts. These impacts should be taken into account during the sequencing efforts discussed by the Wetland Conservation Act Technical Evaluation Panel. Road alignments should be considered that would minimize future wetland impacts. The ghost plat is now shown to be proposed and has been modified to prevent wetland impacts. A permit to take has been submitted to DNR by CCES for all rare species located in the development footprint (areas that will be physically altered/graded/converted to another use). It is important to note that the
