12. Page 20, Other Surface Waters. Please note that it is possible that a DNR Water Appropriation Permit could be necessary for the re-routing or pumping of water during the construction of the pedestrian bridge over Trott Brook. 13. Page 20, Other Surface Waters. There should be a 100 foot setback from the Ordinary High Water (OHW) level of Trott Brook. No clear cutting is allowed in that area, but it is difficult to see in the proposed site plan where the setback is located. Additionally, on Concept Plan (Appendix A) of the EAW under Site Data, it notes, "a portion of the site falls within 300' shoreland overlay from the top of bank of Trott Brook." This should be clearly shown on the map. Shoreland Overlay Limit is identified as a symbol in the legend however the boundary should also be shown on the Concept Plan. 14. Page 23, Rare Species, State. The DNR concurs that there is habitat for the state-threatened Blanding's turtle within the project area. Please coordinate with Regional Nongame Wildlife Specialist, Erica Hoaglund (Erica.Hoa lund state.mn.us) on the need for an avoidance plan to limit impacts to this protected species. We appreciate that the development will use surmountable curbs. In addition to the BMP's mentioned in the EAW, the following mitigation measures are required: • Type 3 wetlands occur in the project area and could provide habitat for the threatened Blanding's turtle. In order to avoid potential impacts, these wetlands should not be dredged, deepened, filled, or converted. Avoid working in these wetlands during the winter because of their potential as overwintering habitat for the Blanding's turtle. • New roads should not be installed where they bisect wetlands or between closely spaced wetland features if possible. MN DNR and partner Data has shown these are the areas with the greatest concentration of road mortality for wildlife species including turtles. If impossible to avoid, contact Erica Hoaglund (Nongame Wildlife Specialist) for BMPs. • Distribute the attached Blanding's flyer to contractors working in the area and report any sightings to Erica Hoaglund. • Due to entanglement issues with small animals, use of erosion control blankets shall be limited to 'bio-netting' or 'natural netting' types, and specifically not products containing plastic mesh netting or other plastic components. These are Category 3N or 4N in the 2016 & 2018 MnDOT Standards Specifications for Construction. Also be aware that hydro-mulch products may contain small synthetic (plastic) fibers to aid in its matrix strength. These loose fibers could potentially re-suspend and make their way into Public Waters. As such, please review mulch products and do not allow any materials with synthetic (plastic) fiber additives in areas that drain to Public Waters. 15. Page 23, Rare Species, State; Appendix E. The DNR has reviewed the Rare Plant Survey Report included in Appendix E and verified the identification of plant specimens for the St. Lawrence grapefern (Sceptridium rugulosum, state listed as a species of special concern). We agree with surveyor recommendations that a follow up survey in spring of 2022 should be conducted to further document the presence of protected state-listed species within the area highlighted in the survey report. Based on the survey and habitat assessment, it appears that there may be DNR Native Plant Communities (NPC) present that may qualify as Rare Natural Communities (RNQ under WCA. If
