impervious land cover and increase the amount of traff c and number of buildings. Environntental effects could include increased surface runoff into the lakes with a resulting loss ojwater quality. Al! rules of the Rice Creek Watershed District will be met and potential impacts mitigated through best management practices when development occurs to minimize potential impacts to the lakes. Potentia! environmental hazards due to past site uses, such as soil contamination or abandoned storage tanks, or proximity to nearby Tzazardous liquid or gas pipelines are not anticipated. 10. Cover types. Estimate the acreage of the site with each of the following cover types before and after development: Before After Types 1-8 wetlands 17.75 17.75 Lawn/landscaping Wooded/forest 27.75 26.54 Impervious surfaces Brush/Grassland 2.30 230 Other Cropland 0.00 0.00 TOTAL If Before and After totals are not equal, explain why: Before After 25.00 24.75 21.84 26.65 0.00 0.00 94.64 94.64 11. Fish, wildlife and ecologically sensitive resources a. Identify fish and wildlife resources and habitats on or near the site and describe how they would be affected by the project. Describe any measures to be taken to minimize or avoid impacts. A review of the Minnesota Department of Natural Resources web site was completed for endangered and threatened species. Minnesota's Federally Listed Threatened, Endangered, Proposed, and Candidate Species County Distribution list (see Attachment 13) showed that Ramsey County is within the known or historic range of the Bald Eagle, but no known nesting sites are in the immediate area. Temparary impacts on wildlife will include the disruptive effects of construction, including excavation, stockpiling of soils and materials, noise, potential erosion and sedimentation, and vehicle movement. Habitat may be altered by the actual e.rcavation or placement ofstockpiled earth or bedding. Some small species may be forced to leave their territories within the proposed project area and compete with established species in nearby areas. Larger species may be forced to relocate to portions of their territories that are not impacted. Seasonal activities, such as nesting or mating, may be disrupted or curtailed, depending upon the season of construction and the species. Habitat altered during construction wi/l be restored to pre-existing contours and re-vegetated. A review was completed by the U.S. Fish and Wildlife offce for the site. Its comments are included in Attachment 12. According to the review, foresPed habitat surrounding both Lake Johanna and Little Lake Johanna provide important nesting habitat for migratory birds such as warblers and other songbirds. In order to avoid impacts to these habitats, these will be preserved as recommended by the U.S. Fish and Wildlife review. If it is necessary to remove individual trees, native trees will be planted following any development and as much buffer as possible will be maintained to enhance_ fish and wildlife habitat, as recommended by the U.S. Fish and Wildlife review. b. Are any state-listed (endangered, threatened or special concern) species, rare plant communities or other sensitive ecological resources such as native prairie habitat, colonial waterbird nesting colonies or regionally rare plant communities on or near the site? Yes X No If yes, describe the resource and how it would be affected by the project. Indicate if a site survey of the resources has been conducted and describe the results. If the DNR Natural Heritage and Nongame Research program has been contacted give the correspondence reference number: _. Descnbe measures to minimize or avoid adverse impacts. 12. Physical impacts on water resources. Will the project involve the physical or hydrologic alteration - dredging, filling, stream diversion, outfall structure, diking, and impoundment - of any surface waters such as a lake, pond, wetland, stream or drainage ditch? X Yes _ No Pnge 5
