Overview
The Tappan Zee Bridge/I-287 Environmental Review is being conducted in accordance with all applicable federal and state requirements, including the
- National Environmental Policy Act (NEPA) (This is an external link and will open in a new browser window)
- State Environmental Quality Review Act (SEQRA) (This is an external link and will open in a new browser window)
The study process includes:
Alternatives Analysis (AA): The Alternatives Analysis, completed in January 2006, identified more than 150 suggestions on how to improve conditions in the Tappan Zee Bridge/I-287 Corridor. After further investigation, those 150 suggestions were combined into 16 different scenarios that were analyzed for their environmental impact, constructability, cost and ability to improve mobility in the I-287 Corridor. The six alternatives that remained at the end of that screening process are detailed in the Alternatives Analysis report.
Environmental Impact Statement (EIS): The Tappan Zee Bridge/I-287 Environmental Review will be conducted as a two-tiered process. An initial EIS will evaluate plans for improving the I-287 corridor (including the Tappan Zee Bridge) and assess transit options for the corridor, identifying a transit mode for the corridor, its general route and its termini. A second EIS will focus on the details of integrating that transit mode into the communities it will serve, including route specifics and transit station locations and designs. A final decision on the first EIS document will initiate work on the second.
The project is soliciting comments, through March 31, 2008, as part of our scoping update process. Comments will be addressed in the Scoping Summary Report to be issued this spring. Also this spring, we expect to select a transit mode(s), whether commuter rail, bus rapid transit, light rail, or a combination. The transit mode(s) selection will determine which alternatives undergo a rigorous and comprehensive analysis as part of the DEIS.
Your feedback on the environmental review process is welcomed. The Project Team looks forward to meeting with you throughout this phase.
Look Ahead:
- Seek input from the public
- Issue Scoping Update Summary report
- Select transit mode or modes
- Develop detailed contents of the DEIS
- Prepare and circulate DEIS for comment
- Public hearings on DEIS
- Prepare Final Impact Statement (FEIS)
- Issue a Record of Decision (ROD)
Each step in the EIS process includes efforts and activities to gain public input. Learn how to:
