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 obtain 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 CCES 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 presence of rare species onsite is largely a function annual soil disturbance/farming practices. Once farming practices on the site cease (with or without development), rare species occurrence on the site is predicted to drop. Per Kjolhaug Environmental Services. • Geotechnical A geotechnical evaluation was completed in response to the concerns over draining the adjacent Pin Oak wetland and impacts to adjacent wells. 1. The introductory paragraph and overall report shall provide recommendations for not only “dewatering” but also reference the” large borrow areas (Ponds 200 & 300) adjacent to existing wetlands”. To be provided with updated Geo report. 2. The applicant shall provide a map of identifying the location and quantity of piezometers and another map of auger probes. To be provided with updated Geo report. 3. The applicant shall provide an evaluation of subsurface geologic feature mapping that can suspend water, or drain with the ground water flow in the absence of geologic “lens”. The Minnesota Geologic survey would be a good reference and soil augerings, mentioned above, to verify lens or no lens.
