The Tracks at Brea is a four-mile linear park and trail that repurposes an old railway corridor through the city. Opened in segments by 2017, it features separate bike and pedestrian paths connecting neighborhoods to schools and sports parks. Organic-Lock Stabilized Aggregate was utilized for the soft-surface pedestrian trail running alongside the paved bike lane. This OLSA pathway provides a jogger- and walker-friendly experience and meets accessibility standards.
