East Bay Regional Park District Commits $3.2M to Trail and Culvert Stabilization Across Lamorinda

The East Bay Regional Park District Board of Directors authorized a $3.2 million emergency infrastructure and erosion control allocation on Sunday, funding vital geotechnical repairs and drainage restorations across popular open-space parklands in Lafayette, Moraga, and Orinda. The preventative stabilization project targets hillside trail segments vulnerable to storm runoff along the Lafayette-Moraga Regional Trail and Briones Regional Park.

Park district engineers detailed that consecutive wet winters severely compromised drainage culverts and earth embankments, triggering localized slope slippage near St. Mary’s Road and Moraga Way. The approved capital plan deploys heavy rock rip-rap, bio-engineered willow mattresses, and upgraded galvanized steel culverts to redirect storm torrents away from steep trail embankments, preventing catastrophic trail washouts.

Park District Director Dennis Waespi highlighted that safeguarding Lamorinda’s cherished regional trails is critical for public safety, wildfire access, and ecological preservation. Waespi noted that these unpaved pathways serve not only thousands of hikers and equestrians weekly but also function as designated emergency evacuation routes and firebreak access points for the Moraga-Orinda Fire District.

Construction contractors will commence initial grading operations on Monday, October 26, focusing first on the upper ridge trails in Briones before moving into the valley corridors. Park officials affirmed that trail closures will be clearly posted at all trailheads and on the district’s digital mapping portal, with detour signage directing recreationists around active heavy equipment zones.

Environmental conservationists in Lamorinda praised the district's reliance on bio-engineered willow plantings alongside traditional rock revetments, noting that native vegetation establishes deep root matrices that naturally bind fragile hillside soils while preserving creekside wildlife habitats along Las Trampas and Moraga creeks.

Regional hiking clubs and school outdoor education coordinators commended the park district's proactive scheduling, noting that early intervention prevents permanent trail closures during severe atmospheric river seasons. Park staff will inspect all culvert outflows weekly throughout the winter rainy months.

The public can track real-time trail condition updates and construction milestones through the East Bay Parks online advisory map. The district will host an open community briefing on Saturday, November 7, at 10:00 AM at the Lafayette Community Center to explain the long-term watershed protection benefits of the infrastructure upgrades.
