Augustin Bernal Mountain Bike Trail Design

The City of Pleasanton wanted to create an engaging experience within Augustin Bernal Park that would encourage mountain bikers to use the designated trail and reduce the desire to build unauthorized trails and trail features. Dudek redesigned the trail to widen, stabilize, and improve existing sections while minimizing impacts to protected species on the project site.

Project Facts
  • City of Pleasanton
  • Alameda County, California
  • Trail connects to the East Bay Regional Park District’s Pleasanton Ridge Regional Park trail network
  • Jumps, drops, and berms were added to improve the experience
  • Snake habitat was improved by decommissioning ad hoc trails

The Challenge

Augustin Bernal Park experienced significant erosion and habitat degradation due to off-trail mountain bike use and unauthorized trail construction, so the City needed to create an engaging designated mountain bike trail to discourage off-trail use. The presence of Alameda Whipsnake habitat in the surrounding areas also presented permitting challenges.

The Solution

Dudek experts, including an avid mountain biker, walked the trail to determine optimal alignment and areas best suited for fun features. By undertaking “in-field” design using maps and GPS, our landscape architects designed the trail to fit the landscape with minimal habitat impacts. Our biologists also consulted with the United States Fish and Wildlife Service (USFWS) to determine which ad hoc trails needed to be decommissioned to protect Alameda Whipsnake habitat. To obtain final environmental clearance, Dudek’s CEQA team prepared a mitigated negative declaration (MND).

The Impact

With its improved design, the new trail is a focal point for off-road mountain bike use and serves as a model for additional mountain bike trails in the area.
