Chandler's Rio Santiago began operations in August of 2013. Chandler's, due to their reputation in the region for operating Inert Fill sites, was brought in to manage the import of inert fill for a large development site. With close to a million tons of import needed, Chandler's managed the stockpiling of inert materials and the site processing of recycled Crushed Miscellaneous Base and Screened Sands.

As of September 4th, 2015, Chandler's Rio Santiago will be temporarily closed while a possible development plan and site overlook will be undertaken.
