this alignment is approximateiy .80 acres. A permit to alter the wetlands will be obtained from the DNR prior to the construction of the prqiect. This will be in addition to the permits listed in item B that wilt be acquired. As p~t of thc pc~it, thc City will have to ~figa~c the loss of thc `*,efi~ds. The contractor will ~ r~uired to comp}y with an erosion and sedimen~ control plan tominimize disturbance of the adjoimn~ wetland areas. Also, thc contractor `*,ill be required to adhere to a least damage schedule minimizJn~ .impacts on witdlif¢ du~ng thc nesting sgason. Surface Water Qu',dity Surface water runoff from the projec~ `*'ill rio,.,,' into the wetlands through the storm sewer system. The outlets of this drainage system will include skimmers in retention basins to allow for the removai of silt and suspended sol_ids. The wetlands that do not haw a natural outle.'s `*,il] allow the runoff to percolate into the ~ound water. Erosion control measures will be adhered to dunng construction and all disturbed ar:as will be landscaped and vegebative cover `*,ill b: maintained to prevent subsequent erosion. Air Pol}ution, Dust and Noise Dust, air and noise impacts will occur during consu-uction. Dust control measures ',,,,ill be used when needed and hours of construction operation ',,itl be limited through contract requirements to minimize noise impacts. The long term impacts on air quality should be positive since the road alignmem wilt reduce wave} time on City streets. Noise levels associated with 40 m.p.h, traffic are within acceptable levels. Fish and Wildlife Approximately 3.5 acres of wooded cover will be removed for the construction of the roadway. Additional).,,,, another 6.75 acres of grassland will be disrupted. The road project will also impact an addinonat .80 acres of b,peJII wetland. With the completion of the project, the CiU' will see a loss of 6.3 acres of various habitats. This `*,ill be somewhat offset by the ruff restoration within the right-of-way. Archaeological and ,Historical Resources The proposed project has a probability of containing prehistoric archaeological sites. Therefore, an archaeological survey has been completed with a negative finding of archaeological sites. Parks and Speci~ Resource Areas Construction of this project veil] not create any adverse impacts on parks or special resource areas. Approximately .80 acres of wetland `*,ill be filled. The impact of the action will be mi fig ate& Roads and Traffic The average daily n-affic (ADT) flows for the area affected bv the proposed extension of Sunwood Drive N.\\.'. are estimated ~o be in excess of 5,0(50 at the completion of the connection by the yea: 2010.
