This first phase of the Bob Jones Trail and Bike Path, approximately 1 mile in length and 8 feet wide, begins at Ontario Road and terminates at San Luis Bay Drive. Based on site reconnaissance and field and laboratory investigation, Earth Systems provided geotechnical recommendations for site preparation, grading, foundations, abutment walls, asphalt pavement, and site drainage. During construction, the Earth Systems team provided compaction testing of bikeway subgrade and base.
