Alternatives History

Alternative 1 was dropped from further consideration prior to the draft Environmental Impact Statement (EIS).

In fall 2005, MDOT circulated a preliminary draft EIS to federal agencies that analyzed the City East Alternative  and the Township Alternative.  Analysis of a no-build alternative also was included. After reviewing the draft document, in June 2006 CBP officials requested a new alternative (City West) be considered providing the following:

• Approximately 70-acre plaza
• More than 100,000 square feet of office space, encompassing up to four floors
• At grade plaza
• Pine Grove Avenue relocated west of the plaza
• Include land between Pine Grove and 10th north of the plaza, to Hancock Street
• 100 truck and 40 car parking spaces
• 20 multi-level booths, expandable to 30
• Up to 3 VACIS units
• Outbound inspection mirroring small land border port
• Space for Food and Drug Administration, U.S. Department of Agriculture and others   

Accordingly, MDOT added  Alternative 4, known as the "Customs Hybrid."   This is a modification to Alternative 2, which keeps the plaza in the City of Port Huron and brings most of the plaza down to street level.
