5. Water Quality. Compliance with multiple stormwater requirements will minimize and mitigate potential adverse effects on receiving waters. Project construction will add about 36.32 acres of impervious surface to the site, consisting of streets,homes, and driveways. Stormwater rate and volume controls will limit increases in runoff volume and associated pollutant transport. Stormwater and infiltration basins are expected to mitigate potential adverse effects on water quality. 6. Wetlands and Surface Waters. The project area contains several wetlands and contains a portion of Trott Book on the south side. The project is estimated to include less than 2 acres of wetland impacts. Impacts to wetlands will be required to be reviewed in compliance with the Wetland Conservation Act and mitigation will be required at an appropriate ratio. A pedestrian bridge is proposed over Trott Brook but will not impede watercraft usage within Trott Brook. 7. Wastewater. The project is expected to produce normal domestic wastewater that will be typical of residential developments. The proposed project does not raise wastewater conveyance or treatment capacity concerns. 8. Hazardous Materials. About 47%of the project area has been in agricultural use since at least the 1930s and the remaining area is comprised of wetlands,woodland, and grassland. The site is not known to include environmental hazards. The agricultural land use history suggests low potential for environmental contamination. 9. Ecological Resources. Project development will convert about 93.57 acres of cropland and 25.29 acres of woodland to streets,homes, lawns, landscaping, and stormwater features. The balance of the site will include about 7.37 acres of tree preservation, creation of 17.03 acres of stormwater basins, dedicated wetland buffers adjacent to wetlands, and 21.9 acres of land for a public park. The project may affect the number and type of wildlife species in the area,but changes in wildlife abundance are not expected to be regionally significant. 10. Historic Resources. An archaeological field survey results did not recommend the site eligible for the National Register of Historic Places and did not recommend any further archeological work. 11. Visual Resources. There are no scenic views or vistas on or adjacent to the project area. Substantial effects on visual resources are not anticipated in conjunction with project development. 12. Air. The Minnesota Environmental Quality Board is working on integrating greenhouse gas (GHG) assessment into environmental review. GHG are expected to result from home heating, travel, and other activities. Mitigation and adaption measures can help reduce GHG and climate change impacts. 13. Noise. The project is expected to minimize disturbances caused by construction noise and conform to Minnesota noise rules and standards. 14. Transportation. The Traffic Impact Study recommended measures to reduce traffic delay,but it did not raise safety concerns. B. Cumulative Potential Effects Minnesota Rules 4410.1700 Subp. 7 (B)indicates the second factor the City must consider is"whether the cumulative potential effect is significant; whether the contribution from the project is significant when 8
