From April 16 - October 2018, a portion of the Oursan Trail by Briones Reservoir will be rerouted for a construction project. Trucks will remove accumulated soils from our Briones storage site, cross a portion of the Oursan Trail, exit off Bear Creek Road then travel westbound toward Camino Pablo.
For details about the construction, visit the Trench Soils Removal Project.

On July 16, 2018, two trail segments of EBMUD trails in the East Bay were opened to bicycles. The multi-use segments on established service roads are open from sunrise to sunset (subject to seasonal closure) and connect to the trail system in Wildcat Canyon Regional Park and within the Pinole Valley. The Pinole Valley and Eagle's Nest Multi-Use trails offer 7.5 miles of new access in the East Bay watershed, now available for cyclists as well as hikers and equestrians.
Permits are required

Trail segment locations and characteristics
- Pinole Valley Multi-Use Trail: This 6.7-mile trail segment consists of service roads, some sections newly open for public use, and provides a continuous stretch of trail spanning from the trailhead at the intersection of Pinole Valley and Pereira Roads up to Pinole Ridge, then terminating at Alhambra Valley Road near the intersection with Pinole Valley Road. On this segment, expect to see rolling terrain through grasslands and oak woodlands with some challenging slopes coming off the ridge.
