II. A, SUMMARY OF ISSUES Wetlands and Wildlife Habitat The permanent loss of at least 6.72 acres of wildlife habitat to road construction cannot be avoided. As a part of the developing metropolitan region, loss of wildlife habitat is virtually unavoidable. The effort, thus, will be to mitigate to the extent practicable by creating a new wetland basin and/or enhancement of existing wetlands on a "no net loss" indicates that a potential project would be creation of a wetland area south of the right-of- way adjacent to wetland 111P. As previously indicated, the City will coordinate efforts with DNR, the Corps of Engineers, and the U.S. Fish and Wildlife service to identify an appropriate mitigation project. Dust, Noise The project will be designed and administered with sufficient controls placed on the contractor to avoid significant impacts during the construction period. Noise impacts from construction activity will be limited by requiring that the contractor use equipment in good operational condition and that they comply with OSHA, State and local requirements. Long term impacts from noise associated with traffic are expected to be well within acceptable levels. No significant impacts are expected and no special measures are anticipated. Storm Water Runoff Increased. impervious surface will increase the rate of runoff over existing conditions. Approximately one half of the right-of-way will be paved. No significant alteration of the existing drainage pattern is proposed.. Runoff will be.-collected in the road ditches and discharged to wetlands in the vicinity of the project. No significant/mpacts are anticipated as a result. Alternate Alignments Alternate 1: The City reviewed both of the alternate alignments as shown on Figure 3 of the original EAW. The more northerly alignment along 156th Avenue N.W. would route the MSA street down a currently developed residential street. This would create an MSA collector street with 22 private driveway accesses which may contribute to additional traffic accidents as these residents attempt to leave their homes. With the additional fight- of-way, several of the existing homes would have only one-half the required setbacks from the MSA road. At the connection with County Road #83, the vehicles traveling west would be required to stop, then turn left onto County Road #83 and make an additional right turn in approximately 2,200 feet. The additional turns required by this alignment would lead to a possible increase in the number of accidents as vehicles accelerate and slow for these turns. These acceleration and deceleration zones would also contribute greatly to the amount of noise caused by the traffic. Alternate 2: Constructing the new roadway in a straight east/west connection. This alignment would generally direct traffic to 154th Lane N.W. which, similar to 156th Avenue N.W., was constructed as a residential street. By recons~cfing this street to MSA standards, 39 single faraily homes and accesses would be direcfly affected. This alignment may be designed to encourage traffic to mm left onto County Road #83 and then right onto 153rd Avenue N.W. The distance for this maneuver would be approximately 1,10t3 feet.
