(Description of Minimization of Water Minimization Efforts:The project has been designed to minimize wetland and stream impacts.Drainage has been designed so that outlets discharging into wetlands have non-
Quality Impacts) erosive velocities to minimize disturbance to the wetlands.The proposed design ties into the existing roadway shoulder minimizing impacts to the wetlands.The existing outfalls
consisted of buried pipe ends with little to no rip rap at pipe outlets.When the project is complete the outfalls will be upgraded to have rip rap outlet pads and improved outfall
channels. The project is not expected to have a significant impact on water quality or quantity downstream of the project.
