An erosion project in Lower Buck Gully is well underway as crews continue to place metal cages on the ground, filling them with rocks brought from a Corona quarry.
The project began last month and should be complete sometime next summer, city officials have said.
The work began with crews constructing a temporary road from the Little Corona beach path to the bottom of the gully. Then crews began to place the multi-layered cages, filling them with rocks that will divert water flow and protect the hills on Evening Canyon and Hazel Drive from collapse.
The project also will remove invasive plants and wildlife.
"Right now, it's like a total jungle," said Robert Stein, an assistant city engineer.
Some invasive plants have been removed, he said, including all but one clump of arundo.
"That's the most invasive plant in Buck Gully, and that's the last of it," Stein said, pointing to a patch near where a pile of rocks is stored.
