Location Study Details
Study Process
The National Environmental Policy Act (NEPA) is an important component of the Route 460 Location Study process. This process includes:
- Scoping: As the first phase in the location study process,
this is an early and open process for determining the scope of issues
to be
addressed, and for identifying the significant issues related to
the proposed
improvements.
Scoping helps identify the sensitive resources in the study area. It also serves as the basis for identifying and selecting alternatives.
- Purpose and Need: Provides the screening criteria and
reason for the study.

- Alternatives Development: This consists of two components,
Preliminary Alternatives and Candidate Build Alternatives (CBA).
During this stage, the team does the following:
- Develops Conceptual Alternatives to address the project needs
- Screens the Conceptual Alternatives to produce a set of Candidate Build
Alternatives
- Defines a No-Build, Transportation System Management and Mass Transit
Alternatives
Since the February 2004 citizen information meetings, public and agency comments have been used to screen the Conceptual Alternatives. The CBAs have resulted from this screening process.
- Develops Conceptual Alternatives to address the project needs
- Evaluation of Impacts: After the CBA’s have been
identified, the study team will conduct a more detailed evaluation of
environmental impacts. The resources analyzed for each CBA include, but
are not
limited to:
- Air quality
- Historic properties
- Hazardous materials
- Indirect impacts
- Quality of wetlands and streams
- Threatened and endangered species
- Noise
- Park, recreation and open space
- Social and economic impacts
- Draft Environmental Impact Statement (DEIS): Once the
environmental impacts have been analyzed for each alternative, they are
documented in a preliminary report, the DEIS, and circulated for public
and
agency review and comment prior to the public hearings.
- Location public hearings: The location public hearings are
conducted once ample time has been given for the public and agencies to
review
the DEIS.
After the public hearings are held and the comments are received on the DEIS, the CTB selects the preferred alternative.
- Final Environmental Impact Statement (FEIS): After the CTB
selects their preferred alternative, the FEIS is prepared. The FEIS
documents
the action of the CTB, responds to substantive comments
received from interested
parties on the DEIS and is presented to the
Federal Highway Administration
(FHWA) for their final
decision.
- Record of Decision (ROD): The ROD is a public document that reflects FHWA’s decision. It includes the rationale behind that decision and commitment to monitoring and mitigation.
