Examples

Programmatic Section 4(f)

  • Ohio – This is a link to the Nation’s first 4(f) Programmatic Agreement. Section 4(f) Programmatic Agreements are allowed for under the Section 4(f) law and can help to streamline the transportation development process.
  • North Dakota Programmatic 4(f). This programmatic agreement between North Dakota Department of Transportation, FHWA, and the U.S. Fish and Wildlife Service allows for minor wetland and/or grassland easements in areas adjacent to Section 4(f) Resources. The programmatic agreement provides that with written concurrence from the referenced agencies minor impacts to easement wetlands and grasslands may occur to avoid greater impacts to non-easement wetlands if the Section 4(f) property is avoided.
  • Pennsylvania DOT Programmatic Section 4(f) Checklists –These checklists streamline the Section 4(f) process for PennDOT by providing programmatic checklists for minor impacts to bridges, historic sites, and parks. There are also checklists for de minimis use, Net Benefit, and temporary use.
