LA CRESCENTA — Los Angeles County officials on Tuesday assured foothill residents that several measures were being taken to ensure the controversial sediment pile would remain stable as the winter rain season kicks into full swing.
The county Department of Public Works and the Flood Control District have been working with a geologist to examine the so-called Dunsmuir sediment placement site by taking dirt samples and using a massive processor that sifts out debris to make sure the dome is properly constructed, Mike Miranda, a public works associate civil engineer, told residents on Tuesday.
Crews also installed a 42-inch concrete pipe to ensure the site drains properly, he added.
County officials are not expecting the Markridge Road site to reach its 2-million-cubic-yard capacity for the next few years, he added, although just 472,000 cubic yards of space remains.
"It is very hard to predict when it will actually get to capacity," Miranda said.
