April 6, 2018  Closed Portion of Santa Ana River Trail to Reopen April 7

A portion of the Santa Ana River Trail from Memory Lane in Santa Ana to Taft Avenue in Orange was closed on January 22, 2018, to the public for an environmental remediation project. It was anticipated to remain closed for up to three months.

The County has made significant progress on the project, and a modified public access route will be restored April 7, 2018.

While environmental remediation work is ongoing in some areas, the work zones will be secured by temporary construction fencing. A slightly modified trail route will allow public use of a trail for hiking, bicycling, and equestrian activity only while being separated from continuing project and maintenance activities.
