The Jeffrey Open Space Trail, the product of extensive community input and consensus, is a unique resource for the residents of the City of Irvine. This open space corridor constitutes an important element in the City's overall open space system, linking the conservation and open space lands within the City. The trail will travel approximately 5 miles through Irvine, from just past Portola Parkway in the north to the Quail Hill open space in the south. Currently, the one-and-a-half mile section between Interstate 5 freeway and Barranca Parkway is in design.
The Jeffrey Open Space Trail provides a key linkage extending from the Pacific Ocean to the Santa Ana Mountains and Cleveland National Forest. The Jeffrey Open Space Trail Community Consensus Plan focuses specifically on the portion of the Spine extending from Interstate 5 to the Natural Communities Conservation Plan Lands north of Portola Parkway.
