What is the purpose of this Project?

The purpose of the I-93 Exit 4-A Project is to reduce congestion and improve safety along NH 102, from I-93 easterly through downtown Derry and to promote economic vitality in the Derry/Londonderry area. Because current traffic congestion along NH 102 affects the vitality of local businesses and community character, the Project will be designed to alleviate peak period congestion along NH Route 102 through downtown Derry by separating through-traffic on NH 102 headed for the Interstate system from local, destination-oriented traffic. The Project will also be designed to improve interstate access to the east of I-93 for commercial and industrially zoned lands in both Derry and Londonderry. This coordination will allow for their planned and orderly development and will promote economic growth in the Derry and Londonderry area.

Who is involved?

Because this Project extends over multiple jurisdictions and intersects with the Interstate system, a collaborative approach is critical on this project. The New Hampshire Department of Transportation (NHDOT) is therefore working in partnership with the Federal Highway Administration (FHWA) and closely with the consultant team led by Fuss & O'Neill, Inc., as well as the public and representatives from an Environmental Impact Statement Review Team (EISRT). The EISRT includes representatives from NHDOT, FHWA, Londonderry, Derry, and the consultant team. NHDOT is also working with other cooperating agencies including the U.S. Army Corps of Engineers (USACE), U.S. Environmental Protection Agency (USEPA), New Hampshire Division of Historical Resources (NHDHR), and the New Hampshire Department of Environmental Services (NHDES). Cooperating and participating agencies for the SDEIS will confirmed and a Coordination Plan prepared pursuant to FHWA's 23 USC 139 environmental review process (as amended by the FAST Act in 2015). The Coordination Plan will identify the roles and responsibilities for each agency and will include a detailed project schedule.

What is an environmental impact statement (EIS)?

The National Environmental Protection Act (NEPA) “requires Federal agencies to prepare environmental impact statements (EISs) for major Federal actions that significantly affect the quality of the human environment. An EIS is a full disclosure document that details the process through which a transportation project was developed, includes consideration of a range of reasonable alternatives, analyzes the potential impacts resulting from the alternatives, and demonstrates compliance with other applicable environmental laws and executive orders. The EIS process is completed in the following ordered steps: Notice of Intent (NOI), draft EIS, final EIS, and Record of Decision (ROD).” Consistent with the FAST Act, a single document combining the FEIS and ROD was utilized.

For more information on the EIS process, please see: https://www.environment.fhwa.dot.gov/projdev/docueis.asp.

What is a supplemental Draft EIS?

A supplemental EIS is required under NEPA when changes in the proposed action or new circumstances would result in significant environmental impacts not evaluated in the previous DEIS or FEIS (23 Code of Federal Regulations [CFR] 771.13). The purpose of this SDEIS is to provide an up-to-date assessment of the I-93 Exit 4A Project that considers changes in the design of the alternatives (through updated preliminary engineering studies), changes in the existing environment, changes in environmental regulations, and other “significant new circumstances or information relevant to environmental concerns have a bearing on the proposed action or its impacts” (40 CFR 1502.9 (c)(1)). New circumstances affecting the Project include, but are not limited to: the final design for the widening of the I-93 mainline in the Project area, approved developer plans for new mixed-use development on both the east and west sides of I-93 (Woodmont Commons), the chloride total maximum daily load (TMDL) for the Beaver Brook watershed, and updated demographic projections affecting future travel demand, among other changes.

Pursuant to Council on Environmental Quality (CEQ) and FHWA regulations, the SDEIS is subject to the same distribution and public review requirements as the previously published DEIS, except that scoping is not required (23 CFR 771.130(d)).
