CenterLine LRT

Orange County, CA

IBI Group has a long history of working for the Orange County Transportation Authority (OCTA) to advance the CenterLine light rail transit project in Orange County. This history began in 1994, when IBI Group collaborated as a subconsultant on the Corridor Major Investment Study (MIS), which evaluated a full range of high capacity transportation options for the identified urban transit priority corridor in Orange County. In 1998, IBI Group as prime consultant led the Urban Rail Detailed Conceptual Engineering and Environmental Study, to further advance the project by fully defining a 28-mile urban rail system for central Orange County. The project included planning, engineering and environmental study phases, culminating in the preparation of a Draft Environmental Impact Statement/Draft Environmental Impact Report. In 2001, the cities of Santa Ana, Irvine and Costa Mesa passed resolutions in support of a light rail alignment in those cities and requested that OCTA proceed into Preliminary Engineering (PE) and Environmental Study. IBI Group is now a major subconsultant to Parsons Brinckerhoff in conducting PE – assisting OCTA and the three cities in accelerating the CenterLine from planning to design. IBI Group has primary responsibility for station architecture, rail base architecture, transit oriented development and station area planning, traffic engineering, and civil engineering of streets and utilities for the 9-mile starter segment. The PE phase will be complete by August 2004.
