Vulcan begins Azusa Rock reclamation, says ‘Mayan steps’ removal is 20% completed
Since beginning operations at its Azusa Rock Quarry in September, Vulcan Materials has spent some time on reclamation of the site in California.
The company has installed 30- to 50-foot high conventional benches and will convert them to 1- to 2-foot “microbenches” by August 2015, the San Gabriel Valley Tribune reports.
The benches will be hydroseeded — a process of adding native vegetation — every 25 feet, removing the current “Mayan steps” at the site, Azusa Rock Project Manager Mike Radford told the San Gabriel Valley Tribune.
The reclamation is part of an agreement between Vulcan and the city of Azusa. The two spent years in legal battles before reaching an agreement in May.
Jeff Cameron, Vulcan manager of permitting and compliance, told the San Gabriel Valley Tribune that habitat restoration company Nature’s Image is creating the “bright green” hillside, which is now about 20-percent finished.
The steps should hide any visible evidence of previous mining, Radford said.
In addition to the Mayan steps, Vulcan is taking other efforts to reclaim portions of the Azusa site, including adding a 9-mile trail around the western side of the property to the Fish Canyon Falls. The trail, which is also part of Vulcan’s agreement with the city, must be completed by Aug. 20.
Radford said no blasting has taken place yet this year and Vulcan intends to use heavy-duty vehicles that should help the operation keep its number of blasts under its limit of 100 per year.
