City of Concord and Markham Arboretum Dedicate Galindo Creek Canopy Deck and Sensory Trail at Markham Nature Park

Parks planners with the City of Concord Parks & Recreation Department and volunteer horticulturists from the Markham Regional Arboretum Society dedicated an elevated redwood Galindo Creek Canopy Observation Deck, a half-mile Braille-and-tactile botanical loop, and an outdoor stone ecology classroom on Sunday morning at Markham Nature Park and Arboretum at 1202 La Vista Avenue (off Cowell Road) in Concord. Encompassing 16 acres of riparian woodland, international tree collections, and demonstration gardens gifted to the city in 1966 by Ira and Bea Markham, the park serves as a living botanical laboratory for Mount Diablo Unified School District classes and Diablo Valley walkers.

Cantilevered above the shaded bend of Galindo Creek, the new 450-square-foot redwood-and-steel observation platform features clear-tempered glass toe panels so children and wheelchair users can peer directly down into the perennial stream channel and canopy layer of mature California buckeyes, black walnuts, and dawn redwoods. A gently sloped 1:20 decomposed-granite ramp links the deck to the La Vista Avenue entrance gate.

Along the adjacent half-mile International Tree Trail, docents mounted forty-two anodized-aluminum botanical plaques embossed in Grade 2 English Braille, raised tactile leaf-vein reliefs, and QR audio guides recorded in English and Spanish. Beside the demonstration orchard, masons built a semicircular Sonoma fieldstone amphitheater seating thirty-five students for hands-on soil and watershed lessons.

The $240,000 arboretum education project was funded through a California Natural Resources Agency Urban Greening grant and Markham Regional Arboretum Society donations approved by the Concord City Council.
