piepaiaiion process because of tritium levels in the bedrock aquifer. Maintaining clean water infiltration is essential. Issue addressed in Items 13,17 and 19. - The clean-up of all possible contamination on the site must be assured, including the BNSF railroad and the derelict farm. Issue addressed in Items 19 and 20. - Coordination between infiltration practices and wellhead/groundwater protection is essential and should be a key design factor; that is, pre -filter pollutants prior to infiltration through such means as use of native vegetation swales and small-scale detention near parking lots, minimized pavement, or possible clay sealing of ponds that drain pollutant sources that could degrade groundwater (if any such sources are even allowed in the RTC). Issue addressed in Items 17 and 19. - An assessment of the potential for the increased demand from the municipal system to impact local wells should be done. Issue addressed in Items 13 and 19. Planning - The site should be consistent with the local comprehensive plan, including the Critical Area component, and also consistent with 1VINRRA and gild and Scenic River" status of the River across Highway 10. Issue addressed in Items 8, 11, 14 and 27. Natural Resources - The existing wetlands should be incorporated into the surface water system as an amenity that adds to the environmental benefits of the site. Any alteration of wetlands must be mitigated according to the WCA process. Issue addressed in Items 11, 12 and 17, - The few mature trees there are on the site should be preserved. Issue addressed in Item 11. - The project should relate the natural features of the site to the Regional Park, featuring native vegetation types typical of the Anoka Sandplain. Issue addressed in item 11. Hazardous Material Transport - There are many trains per day on the BNSF tracks. Some surely contain hazardous material that could pose a risk if spilled. Issue addressed in Item 20, 31-4
