11. Fish, Wildlife, and Ecologically Sensitive Resources a. Describe fish and wildlife resources on or near the site and discuss how they would be affected by the project. Describe any measures to be taken to minimize or avoid adverse impacts. Most of the site is covered with grasses and other low vegetation. Approximately two-thirds of the line of evergreen trees will remain after construction of this project. Some of the trees will be left.. Most of the wetland will be avoided. New wetland area (two times the impacted area) will be created on the site to mitigate for the wetland area impacted by this project. The conversion of the undeveloped area to a school with ballfields and other facilities will result in displacement of species not suited to the new habitat. This may result in an overall decline of those species as displaced wildlife competes with existing populations in nearby suitable habitat. Wildlife suited to the activities and landscape of the school grounds will adapt to the proposed changes. b. Are there any state -listed endangered, threatened, or special -concern species; rare plant communities; colonial waterbird nesting colonies; native prairie or other rare habitat; or other sensitive ecological resources on or near the site? EiYesEINo If yes, describe the resource and how it would be affected by the project. Indicate if a site survey of the resources was conducted. Describe measures to be taken to minimize or avoid adverse impacts. There are no known rare or endangered species or ecologically sensitive resources located in this area. The DNR Natural Heritage Program completed a database search which shows no record of rare or endangered species or ecologically sensitive resources. 12. Physical Impacts on Water Resources Will the project involve the physical or hydrologic alteration (dredging, filling, stream diversion, outfall structure, diking, impoundment) of any surface water(lake, pond, wetland, stream, drainage ditch)? DYesIENo If yes, identify the water resource to be affected and describe: the alteration, including the construction process; volumes of dredged or fill material; area affected; length of stream diversion; water surface area affected; timing and extent of fluctuations in water surface elevations; spoils disposal sites; and proposed mitigation measures to minimize impacts. There is a ditch /creek along the south side of I -35W. There is a culvert which conveys runoff under I -35W to the north. The ditch and the culvert are maintained by Minnesota Highway Department personnel. The wetland is adjacent to the ditch and the natural drainage flow is from the wetland to that ditch. No other existing waterways are located on the site. The grading plan includes the construction of a water quality pond according to MPCA rules and NPDES standards to handle runoff during and after construction. The existing storm sewer piping will continue to convey flow away from the site. No significant change in the quantity or water quality is anticipated as a result of this project. 13.Water Use a. Will the project involve the installation or abandonment of any wells?DYesEINo For abandoned wells, give the location and Unique well number. For new wells, or other previously unpermitted wells, give the location and purpose of the well and the Unique well number (if known). No individual wells have been identified. If any wells are found on the site, they will be properly abandoned according to guidelines and Minnesota Department of Health Rules. b. Will the project require an appropriation of ground or surface water (including dewatering)? DYesIENo If yes, indicate the source, quantity, duration, purpose of the appropriation, and DNR water appropriation permit number of any existing appropriation. Discuss the impact of the appropriation on ground water levels. Dewatering is not anticipated at this time. If it is necessary, the contractor will be responsible for obtaining a water appropriation permit from the MnDNR. c. Will the project require connection to a public water. supply? ®YesDNo If yes, identify the supply, the DNR water appropriation permit number of the supply, and the quantity to be used. ISD#12.EAW -
