Tier 1, US 8 Environmental Impact Statement (EIS) - Environmental information

Wetland area near US 8.


Environmental Impact Statement (EIS)

An EIS is the decision document for a major highway project like US 8 . The EIS pulls together community and agency interests and recommends a future course of action.

An EIS is required by the National and Wisconsin Environmental Policy Acts for projects with potentially significant social, economic, natural resource and other impacts. The Federal Highway Administration (FHWA) is the lead agency for the EIS which is prepared in accordance with their guidelines.

The following document(s) are in Adobe PDF PDF format.

Final Environmental Impact Statement (FEIS)

The Wisconsin Department of Transportation (WisDOT) completed the FEIS on 40 miles of US 8 between WIS 35 (North) and US 53 in Polk and Barron Counties. The FEIS identifies the selected preferred alternative for the corridor.

An important aspect of the FEIS is its designation as a “Tier 1” environmental document. The Tier 1 document is used to outline the basic location and design vision for the 40-mile US 8 corridor between WIS 35 (N) and US 53. Future phases, called Tier 2 and Tier 3, will be used to provide detailed engineering for corridor preservation efforts and eventual design and construction. Additional environmental documentation will also be required. While it could take decades to complete the entire corridor, the preferred alternative for US 8 forms the foundation for WisDOT’s approach to funding and scheduling the highest-need sections of improvements for this corridor.

The FEIS has been published and is available below. Hard copies are available for viewing at the Northwest Region Transportation office, 1701 North 4th Street, Superior, WI.

Draft Environmental Impact Statement (DEIS)

Public input on the DEIS document, alternatives, and impacts was solicited during the summer of 2006 following its publication in early June 2006.

Selection of a preferred alternative for US 8 was made by WisDOT and is identified in the FEIS after evaluating engineering and environmental factors for the various alternatives, and careful consideration of comments from various agencies, affected communities and property owners.

WisDOT environmental information

WisDOT projects and construction sometimes change the natural environment around a project area. To minimize the effects of road construction and development WisDOT works to reduce change to the natural environment and leads several efforts to restore project areas.
