Key Terms

Temporary Occupancy

A temporary occupancy of land is so minimal that it does not constitute a use within the meaning of section 4(f) when the duration is temporary, the scope of work is minor, there are no anticipated permanent adverse physical impacts, and the when land will be fully restored. There must be documented agreement of the appropriate Federal, State, or local officials having jurisdiction over the resource regarding the above conditions.

Trails

For the purposes of this training, “trails” refers to any shared use path such as sidewalks, bike baths, hiking trails, pedestrian paths, equestrian facilities, or other facilities intended for use by off-road vehicles such as all-terrain vehicles or snowmobiles.

Transportation Enhancement Activities (TEAs)

Transportation enhancement activities are projects that improve communities' cultural, aesthetic and environmental qualities. Eligible activities include bicycle and pedestrian pathways, historic preservation, acquisition of conservation or scenic easements, rails-to-trails projects, and the mitigation of water pollution due to highway runoff.

Tribal Historic Preservation Officer (THPO)

The THPO represents the interests of a tribe on tribal lands in the Section 106 and Section 4(f) processes. When recognized by the Department of Interior (DOI), a THPO acts in lieu of the SHPO and is an official with jurisdiction in the course of the Section 4(f) process for impacts on tribal lands. When a THPO has not been formally recognized by the DOI, he or she fills that function in tandem with the SHPO.
