Los Angeles County Supervisors Zev Yaroslavsky and Mark Ridley-Thomas, Santa Monica Mayor Richard Bloom, Culver City Councilman Micheal O’Leary were among those on hand warning voters of the potential impact of a motion filed in California Supreme Court.

Ridley-Thomas warned that ongoing legal efforts by opposition group Neighbors for Smart Rail could cost the region $90 million dollars and as many as 4,000 jobs – a goal his colleague said the group has had from the start.

“What they’ve wanted to do from Day One is kill this project,” said Yaroslavsky.

The Expo Line – which began running trains between Exposition Park and Culver City in June – is expected to host 64,000 riders a day by 2030 along the $930 million railway.

But Terri Tippit, president of Neighbors for Smart Rail, said running 240 trains a day at street level will greatly interfere with traffic and pose a potential threat to nearby schoolkids.

Tippit has proposed lawmakers instead focus their efforts on the “Subway To The Sea”, a project the group believes “has 100 percent community support throughout” and “will make Expo redundant the day it opens.”
