HELIX Environmental Planning (HELIX) prepared an Environmental Impact Report (EIR), as well as the federal Environmental Assessment (EA) necessary to secure a Presidential Permit from the Department of State, which was the NEPA lead agency for this high-profile project at the U.S./Mexico border. The Cross Border Xpress project included the construction and operation of a 95,000-square-foot facility capable of processing 17,000 passengers daily with an above-grade pedestrian bridge linking the facility in the U.S. with a commercial passenger airport terminal in Tijuana, Mexico. Other project components include on- and off-site roadway improvements, a multi-deck parking structure, and ancillary parking areas. An amendment to the Otay Mesa Community Plan was required to modify the site’s land use and off-site roadway classifications, with the City of San Diego serving as the CEQA lead agency. In addition to managing the NEPA and CEQA documentation, HELIX prepared the noise, community impacts, and air quality/greenhouse gases (GHG) technical studies. The EIR was certified by the City of San Diego and the Cross Border Xpress opened in December 2015. This project won ENR California Best Project for Airport/Transit in 2016.
