Unique Problems

Unique problems are present when there are unusual factors, or when the costs or community disruption reach extraordinary magnitude.

Use

Generally, "use" occurs with a U.S. DOT approved project or program (1) when land from a Section 4(f) site is permanently incorporated into a transportation facility; (2) when there is a temporary occupancy of land that is adverse in terms of the statute's preservationist purposes, or (3) when the proximity impact of the transportation project on the Section 4(f) site, without acquisition of land, are so great that the purposes for which the Section 4(f) site exists are substantially impaired.
