For years somebody has been scooping out massive amounts of earth at La Cienega and Jefferson. I heard that the digging was a huge unknown public works project to build a sewer tunnel from the Valley to the ocean.

Turns out there’s already a major sewer main underneath that intersection, but frankly it stinks. So the city has cracked open the land to install a giant air freshener of sorts. The new Air Treatment Facility will use carbon filters and ravenous bacteria to gobble up those fumes traveling downstream from Toluca Lake. As for all the dirt they’re digging out, you may notice another crew piling it high to build a stretch of the Metro Expo Line, the latest addition to our lightrail system.
