Legacy Parkway Supplemental Environmental Impact Statement (SEIS)

Categorized Under: Environment, Transportation



This project envisioned a 14-mile, four-lane, divided highway, roughly parallel to Interstate 15 northward from Salt Lake City, Utah. ICF designed and oversaw implementation of a public outreach and participation plan to comply with National Environmental Policy Act (NEPA) and ICF’s development of the project’s Supplemental Environmental Impact Statement (SEIS).

The environmental documentation for the Legacy Parkway alignment was the subject of litigation, resulting in the need for the joint federal lead agencies (Federal Highway Administration and Army Corps of Engineers) to re-evaluate the Environmental Impact Statement (EIS) and prepare a supplemental EIS. ICF provided independent review for the re-evaluation process and oversaw the development of additional information needed to complete a legally sufficient supplemental EIS. Our technical work included review of the hydrogeomorphic modeling, analyses of impacts to the Great Salt Lake's ecosystems, and geographic information system modeling of future conditions that included lake level and noise effects.

ICF facilitated partnering sessions and coordinated with UDOT public information staff on media strategies. ICF was responsible for all coordination and logistical efforts associated with a large public scoping workshop and several associated topical breakout sessions. ICF also assisted with the planning and coordination of the public hearing for the SEIS, which was attended by several hundred people. All public outreach activities were coordinated with the U.S. Army Corps of Engineers and Federal Highway Administration. Public controversy surrounding this complex transportation project was minimized due to involvement of ICF. In 2006, the project received an award for NEPA excellence from the National Association of Environmental Professionals.
