This project consisted of construction of a new trail in the City of Diamond Bar. The trail was set in very rough terrain. The length of the trail was approximately 3,000 lineal feet with several switchbacks. Along the trail cobble swales, diverters, lodge pole fencing and two pedestrian bridges were installed. The project also consisted of construction of two picnic shelters; a 12’ shelter and a 30’ shelter, installation of a bench and trash receptacle and an ADA walking trail. GBC performed successfully on this project without any incidents or problems.
