The contractor will be required to comply with an erosion and sediment control plan to minimize disturbance of the adjoining wetland areas. Also, the contractor will be required to adhere to a least damage schedule minimizing impacts on wildlife during the nesting season. (EAW and DNR) Surface Water Quality Surface water runoff from the project will flow into wetland 111P through an existing county ditch system. The outlets for these ditches would be to the wetlands, thus retaining the natural drainage patterns. This wetland does not have a natural outer, which allows the runoff to percolate into the ground water. Erosion control measures will be adhered to during construction and all disturbe21 areas will be landscaped and vegetative cover will be maintained to prevent subsequent erosion. (F. AW) Air Pollution, Dust and Noise Dust, air and noise impacts will occur during construction. Dust control measures will be used when needed and hours of construction operation will be limited through contract requirements to minimize noise impacts. The long term impacts on air quality should be positive since the road alignment will reduce travel time on City streets. Noise levels associated with 40 m.p.h, traffic are within acceptable levels. (EAW) Fish and Wildlife Approximately 1.39 acres of pine plantation wooded cover will be removed for the construction of the roadway. This pine stand is approximately 20 years of age and was planted as tree farm stock and windbreaks. Additionally, another 4.02 acres of brush/grassland will be removed. The road project will also impact an additional 1.31 acres of type IV wetland. With the completion of the project, the City will see a loss of 6.72 acres of various habitats. This will be somewhat offset by the turf restoration within the right-of-way which covers approximately 2.9 acres. Archaeological and Historical Resources The proposed project has a probability of containing prehistoric archaeological sites. Therefore, an archaeological survey will be completed. (Response from the Minnesota Historical Society) Parks and Special Resource Areas Construction of this project will not create any adverse impacts on parks or special resource areas. Approximately 1.31 acres of wetlands will be filled. The impact of the action will be mitigated. (F.,AW) Roads and Traffic -, The average daily traffic (ADT) flows for the area affected by the proposed extension of 153rd Avenue N.W. are estimated to be in excess of 600 at the completion of the connection. The ADT projections are based upon traffic studies completed during 1990- 1992 after the completion of previous links of 153rd Avenue N.W. directly to the east. The City estimates that the proposed connection would not greatly increase the number of Al)Ts. However, the new connection would allow for the reduction in the number of vehicles currently using 156th and 158th Avenues N.W. by approximately 540 ADTs. III
