Accordingly,the post-development scenarlo will not adversely affect wildlife habitat or population resources and may Improve wildlife habitat through site cleanup,additional landscaping, and stormwater ponding. The ultimate development is expected to decrease Impervious surface area by approximately four acres and Increase landscape green space by 0.6 acres. 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?O Yes 0 No 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. Upon written request,the Minnesota DNA Natural Heritage Program conducted a database search to determine If any rare or endangered plants,animals,or communities are located on or within one mile of the site. The search found no known occurrences of rare species or natural features on or within a one-mile radius of the site. Because the site has been developed since 1961 and lacks any significant habitat resources,the DNR's findings confirmed expectations based on site reviews. The DNR Natural Heritage database search results are-attached(Appendix C). 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)?0 Yes Lf No 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 mitigationmeasures to minimize impacts. No surface waters exist on or adjacent to the site Therefore there will be no direct physical or hydrological alteration of any surface water.: 13. Water Use a. Will the project involve the installation or abandonment of any wells?0 Yes RI No 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). The site does not Include any registered active or abandoned water wells according to Minnesota Geological Survey well records.'Three groundwater monitoring wells located west of the New Market building used to observe petroleum product groundwater flow from the Don's Apache Autowash Leakslte(MPCA Leakslte 0000246)..The Phase 1 ESA indicates that no other wells were observed on-site. When MPCA requirements ere satisfied,the monitoring wells will be abandoned In accordance with all applicable local,state,*and.federal regulations. If circumstances require,the monitoring wells may be abandoned and relocated in order to accommodate building demolition and site redevelopment. b. Will the project require an appropriation of ground or surface water(including dewatering)?0 Yes 0 No 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. Based on the depth to static water recorded In borings, on-site monitoring wells,and off-site wells, It is not anticipated that any dewatering will be necessary for site redevelopment. If water appropriation for utility installatlori becomeb necessary,a DNR Water Appropriation Permit will be obtained. Westwood Professional Services, Inc. ��'
