Client: Regional Parks Division, Public Works Department, San Bernardino County
Location: Santa Ana River Bank from from Waterman Avenue to Alabama Street

Project Features:

  • WRC was commissioned to provide planning, design, and construction management assistance services. The project involved civil engineering, bridge structures, and wetlands establishment along the trail.
  • Trail was initially designed following the Caltrans engineering standards (to meet the TEA Funding requirements), however, potential enhancement features and linkage to adjacent wetlands were considered in the planning process.
  • The project involved complicated redesign of storm drain laterals and utilities in order to provide safe trail crossings. Unique safety cover was provided under the railroad crossings.
  • The trail crosses several lined and unlined tributaries; type selection for trail crossings were based on construction costs, maintenance requirements, environmental impacts, erosion resistance, and aesthetic compatibility.
  • Major challenges exist near the Mission Zanja Creek. A trail bridge is to be constructed at the creek crossing. Immediately following the crossing, it is the BNSF railroad. ADA compliance and speed control at the tight areas next to the railroad were successfully managed. The encroachment permit application has been complicated by the involvement of SANBAG, Metrolink, BNSF, and Public Utility.
  • Other challenges include building public trail next to an active landfill and modification of a low-lying bank used for discharge by Gage Canal Company. The environmental issue and public safety forced the team to reconsider alternate route.
