The contractor will guarantee delivery of the asphalt to the Black Rock Campground in Yucca Valley California 92284 and Indian Cove Campground located in Twentynine Palms CA, 92277.

The bulk cold mix will be delivered by dump truck and can be of any type of non-recycled slow cure cold mix asphalt. This material can be delivered by any type of dump truck except for belly dump. The cold mix must be bulk delivered by dump and not bagged.

2.2 The park will require 1,400 tons of 4 inch washed rock to be delivered to the Queen Valley Administration site. This site is located 13 miles into the park from the Twentynine Palms Entrance. This material will be stockpiled and can be delivered by any type of dump truck except belly dump.

2.5 The park requires 10 tons of granite boulders 2-3 foot in diameter. These boulders will be required to be hand picked after a supplying quarry is located. Upon awarding of the contract, the contractor will set up a time for the Trails Supervisor to meet at the rock quarry to identify the boulders that will make up the 10 tons that are required. This is due to the boulders being used in dry stone masonry and the shapes needing to be of a certain type due to specific rock cutting methods being used. After the 10 tons of boulders are identified the contractor will have the boulders delivered to Pinto Wye storage yard which is located 5 miles into the park from the North Entrance in Twentynine Palms.
