The plans, presented Oct. 7 at the Los Angeles County Arboretum and Botanic Garden in Arcadia, remain conceptual. More than 160 people attended the session, viewed design displays and offered feedback, the county Department of Parks and Recreation said in an October news announcement.
The proposals seek to make the canyon more resilient to wildfire, flooding and a changing climate while restoring opportunities for nature education. They follow months of planning with residents, tribal representatives, educators and volunteer docents, according to the county’s Oct. 14 public information newsletter.
One proposed feature, called the Discovery Terrace, would replace a damaged outdoor learning area with places for school groups, families and new visitors. County descriptions of the renderings include stepping logs, a dry streambed, boulders, picnic tables and a sensory trail.
Another concept would turn the site of the destroyed nature center into an outdoor Nature Forum. Plans describe space for small gatherings or quiet reflection, a study area, restrooms, picnic areas and a bridge across dry streambeds. A replacement nature center building is proposed north of the existing parking lot, separate from the old building site.
County Parks described those features in an Oct. 9 announcement as early concepts that remain open to public feedback.
The landscape approach also draws on a 2025 resource management plan. It distinguishes places where visitors could return from remote habitat that would receive stronger protection.
Under that framework, a Preservation Zone would accommodate regular visitors, education areas and interpretive signs. It would include plants able to withstand moderate foot traffic and locations where restoration crews could intervene directly.
A Core Habitat Zone would remain rugged and without trails. The county describes it as a place for sensitive plants and wildlife, with restoration generally left to natural processes rather than routine active work.
Megan Horn, a landscape architect with Studio-MLA who presented the concepts, said the designs respond to Eaton Canyon’s biology, geology and cycles of fire and heavy rain. In the county’s account of the meeting, Horn said, “Nature is bouncing back.” She also stressed the need for people to care for the recovering landscape.
The concepts come as Altadena’s access to the canyon remains restricted. Los Angeles County’s current trail notice says Eaton Canyon and several nearby trails will stay closed at least through Dec. 31, 2027. The county has not established a reopening date.
The fire removed vegetation that had stabilized steep slopes. Subsequent storms brought debris flows and landslides, damaging trails and leaving hazardous ground, according to the county’s trail information. Officials say reopening depends on resolving safety risks, ecological recovery and repairs to trails and bridges.
Restoration work has already begun elsewhere on the property. A four-acre Landscape Recovery Center grows and stages native plants for replanting, helps volunteers and county staff coordinate projects, and supports efforts to reduce erosion and invasive species.
The county also unveiled a separate design for the replacement nature center building in September. That building proposal emphasizes fire-resistant materials and other protections. County officials said $16 million in state funding had been secured for the building, about half its projected cost.
For the landscape plan, the Oct. 7 session was an opportunity for residents to influence what happens before designs are finalized. County Parks Director Norma E. García-González described public feedback as central to the process, telling those gathered, “Your input, your questions, your feedback are exactly what we want to see happen today.”
