Task 3 – National Environmental Policy Act (NEPA) Documentation  
Given the nature of the proposed project and the assumptions that: 1) federal funding will not be involved 
in the development of the proposed project and 2) minimal right -of-way and/or easements (permanent or 
temporary) will be required and will not total at or above one (1) acre and will not warrant any relocations 
or displacements, the project is a likely candidate for classification as a Tennessee Environmental 
Evaluation Report (TEER), which conforms to TDOT’s state -funded environmental review process. This 
determination can only be made, however, by TDOT. If a different level/type of environmental document is 
required by TDOT other than the preparation of a TEER, this effort will be considered Additional Services 
beyond this scope of services. 
One Build Alternative and the No-Build Alternative will be studied. The TEER document will be based on 
functional plans or on preliminary plans (20-30 percent complete) as defined on Page 4-5 of the TDOT’s 
Local Government Guidelines for the Management of Federal and State-Funded Transportation Projects 
(June 2023). 
Task 3.1 – TEER Project Management and Coordination 
The purpose of this task is to plan, organize, and implement the tasks associated with the delivery of the 
TEER review and documentation in a timely manner.  In this task, Kimley-Horn (hereinafter, the Consultant) 
will: 
▪ Maintain direct contact and function as a liaison with the designated representative of the TDOT 
Environmental Division’s NEPA Programs Office, Local Programs Representatives 
▪ Provide periodic (up to bi-weekly) updates to the Consultant’s Project Manager 
 
Task 3.2 – Environmental Technical Studies  
As part of the preparation of the TEER, the Consultant will complete the applicable environmental 
technical studies as outlined below. 
Ecology 
As warranted, based on coordination with TDOT, the Consultant’s subconsultant, Terracon, will provide an 
Environmental Boundaries Report (EBR) in accordance with TDOT standards.  As part of the preparation 
of the EBR, Terracon will perform a jurisdictional waters determination as outlined below:  
Jurisdictional Waters Determination 
 
As part of the preparation of the EBR, if warranted, the Consultant’s subconsultant will provide a Waters of 
the U.S. Determination (i.e., streams and wetlands) for the project area. In performing the jurisdictional 
determinations, the 1987 Corps of Engineers Wetlands Delineation Manual and the 2012 Regional 
Supplement: Eastern Mountains and Piedmont Region, will be closely followed to establish a description of 
the soils, plants and hydrologic conditions of the project area. The Consultant’s subconsultant will perform 
the following tasks: 
 
▪ The Consultant’s subconsultant will perform a desktop and field review of the Project area in order 
to locate potentially jurisdictional waters (wetlands, streams or conveyances) of the US / State. 
▪ The proposed alignments will be assessed including up to 50 feet of width beyond the right-of-way. 
▪ Onsite channels will be assessed using the State of Tennessee’s hydrologic determination criteria 
to establish whether each channel is considered a stream or wet weather conveyance. Potential 
wetland areas will be evaluated using the U.S. Army Corps of Engineers (USACE) criteria, specific 
to the Corps’ Atlantic and Gulf Coast regional supplement. 
▪ Approximate locations of any identified jurisdictional features will be field mapped using GAAS -
enabled Global Positioning System (GPS) handheld units with approximate 1-meter accuracy.
