Hidden Falls Regional Park

Auburn, California

Hidden Falls Regional Park is an 1180-acre open space park in Placer County with many opportunities for passive recreation and multi-use trails. Coon and Deadman Creeks flow through the park along with waterfalls. The park’s expansion allowed for additional planned multi-use trails for hikers, bikers, and equestrians and passive recreational use. Foothill Associates provided trail planning, site design and evaluation, cost estimating, and schematic design of the park access roads and hiking and equestrian staging areas; aesthetic design of three new bridges and an overlook; and park/visitor center site facility rehab. We met with forums of trail users and cultural/educational professionals to develop the thematic design standards. We provided environmental consulting support through impact analysis, mitigation planning, and restoration design. As part of the trail alignment process, our biologists mapped habitats on aerial photographs which our landscape architects then used to help identify significant resources, propose the most scenic locations and most logical access points.
