SEPTEMBER 2016: PUBLIC INFORMATION MEETING

The purpose of the public information meeting is to provide an update on the status of the project and environmental review process.

OCTOBER 2016: NOTICE OF INTENT

The environmental review process formally begins with publication of a Notice of Intent (NOI) in the Federal Register. The NOI explains the role of the agencies and their intent to prepare the EIS, gives a basic description of the project, and invites the public and other government agencies to participate in the process.

JUNE 2016 THROUGH OCTOBER 2018: SUPPLEMENTAL DEIS

An SDEIS will be prepared to comprehensively document the potential environmental effects, both beneficial and adverse, of each alternative. The document will describe the purpose of and need for the project; public participant and agency coordination; and the project alternatives and how they affect land uses, socioeconomic conditions, community character, virtual and aesthetic resources, historic and cultural resources, parklands and recreational resources, transportation, air quality, noise, water and ecological resources, hazardous waste and contaminated materials, greenhouse gases, energy, topography, geology, and soils, construction impacts, environmental justice, and indirect and cumulative effects.

FROM END OF PUBLIC REVIEW TO MARCH 2019: FINAL ENVIRONMENTAL IMPACT STATEMENT/RECORD OF DECISION

After the public comment period on the SDEIS closes, a combined FEIS/ROD is anticipated. The FEIS/ROD will include responses to the public's comments on the SDEIS, as well as any necessary revisions to the SDEIS to address the comments. In addition, the FEIS/ROD will identify the alternative selected for implementation by NHDOT, the Towns and FHWA; present the basis for the decision; identify the alternatives that were considered; and provide information on the adopted means to avoid; minimize, or otherwise mitigate environmental impacts. The FEIS/ROD will be posted online, and a Notice of Availability will be printed in the Federal Register.

2019: FINAL DESIGN & PERMITTING

Following completion of the NEPA review, final design of the Preferred Alternative will be undertaken, along with work to obtain all required environmental permits, as well as initiate acquisition of right-of-way. The product of this stage is a complete set of plans, specifications, and estimates (PS&Es) of required quantities of materials ready for the solicitation of constructions bids and subsequent construction.

2019 THROUGH 2022: CONSTRUCTION PHASE

The construction phase includes all the physical work needed to complete the project, including site clearing, earthwork, paving traffic signals, utility relocations, stormwater treatment areas etc.
