The San Bernardino County Solid Waste Management Division has completed a special project at the Colton Sanitary Landfill (CSL). This landfill, located in Colton, covers 113 acres, with 88 acres used for waste disposal from 1964 to Dec. 31, 2014.

Originally, the plan to close the CSL in 2014 required covering the 88 acres with a 4-foot-thick layer of soil. Since there wasn’t enough suitable soil on-site, about 600,000 cubic yards of soil would have needed to be brought in. Instead, the county chose Agru’s Closure Turf, a material with a synthetic grass top layer, for the final cover. This product is more cost-effective than hauling in dirt, environmentally friendly, and prevents soil erosion, reducing future maintenance and costs.

The project, designed by SWT Engineering and built by Sukut Construction, took 21 months to complete. It included installing the Closure Turf and improving onsite roads and stormwater drainage. This is the first project of its kind for the county and one of the few in California.
