City of Orinda and Friends of Orinda Creeks Dedicate Redwood Riparian Boardwalk and Fern Sanctuary at Orinda Oaks Park

Park planners with the City of Orinda Parks and Recreation Department and watershed restoration volunteers from the Friends of Orinda Creeks dedicated a 140-foot elevated heart-redwood riparian boardwalk, native woodland fern restoration, and hand-set basalt trail steps on Sunday afternoon at Orinda Oaks Park accessed from 70 Orinda Way and Moraga Way in central Orinda. Preserving twenty-six acres of coast live oak woodland, bay laurel ravines, and panoramic hilltop meadows overlooking downtown Orinda, the open-space park links neighborhood footpaths directly toward the East Bay Municipal Utility District watershed trail network.

In the shaded northern ravine where a spring-fed seasonal tributary flows toward San Pablo Creek, winter runoff had previously undercut the narrow dirt footpath and exposed ancient bay laurel roots. Trail engineers installed fourteen hand-driven helical steel micropiles—placed without heavy excavators to protect tree root zones—supporting a five-foot-wide deck of sustainably harvested Mendocino heart redwood with kick-rails and non-slip diamond mesh treads.

Beneath and alongside the elevated boardwalk, Friends of Orinda Creeks volunteers removed invasive French broom and English ivy across 0.8 acres of creek bank. Restoration crews then replanted the shaded understory with 950 native western sword ferns, California buckeyes, snowberry shrubs, and woodland strawberries that filter hillside sediment before water reaches San Pablo Creek's rainbow trout habitat.

At the upper meadow junction, crews also set two engraved Sonoma stone contemplation benches and a bronze watershed trail map funded by a $178,000 City of Orinda park grant. Hikers can view trail routes and volunteer workdays on the City of Orinda Parks and Recreation Portal.
