The Railroad Safety Trail generally follows the alignment of the Union Pacific Railroad right-of-way in San Luis Obispo, CA. The most recent segment was constructed between the right-of-way and California Boulevard near the Cal-Poly University campus.

Earth Systems provided geotechnical engineering, initial site assessment, and geotechnical testing services for several segments of this trail, which has been constructed in phases within the City of San Luis Obispo. Earth Systems conducted:

  • subsurface exploration
  • laboratory testing, and
  • developed geotechnical recommendations for site preparation, grading, pavement sections, and retaining walls.

During construction, Earth Systems provided grading certification of earthwork and observation of foundations for retaining walls.
