Howard R. Green Company <br />Project No. 822530-0030 <br /> <br /> Feasibility Study <br />Yankton Street Road Improvements <br /> Elk River, MN <br /> <br />VI. Implementation Considerations <br /> <br />Implementation of any construction project will have an impact on the <br />environment of the area. Using appropriate erosion control methods and careful <br />monitoring of construction activities can minimize the temporary, shod-term <br />negative effects of construction. <br /> <br />The primary environmental impacts associated with this construction would be <br />potential erosion and loss of trees and vegetation. The potential erosion <br />problems can be avoided through proper planning in the design phase of the <br />project. Construction plans for the project would include an erosion and <br />sediment control plan. During construction, it will be vital that sufficient <br />observation of the contractor be maintained to identify and ensure correction to <br />any potential erosion problems. <br /> <br />VII.
