The future of city streets is being decided as Angelenos vote on the HLA measure on Tuesday.

A citizen-led ballot initiative aims to force the city of Los Angeles to add hundreds of miles of bike lanes and bus lanes to make streets safer for pedestrians and cyclists.

If passed, it would require 338 miles of protected bike lanes and add hundreds of unprotected lanes, transforming some of the region's most historic thoroughfares. Ventura Boulevard in the San Fernando Valley Dozens of streets, including Soto Street on the East Side, will have new bike lanes. Supporters say the measure would add another 300 miles of bus improvements, including bus lanes and prioritization of transit signals.

“There's a lot at stake here, and it's not just about this measure. It's about what kind of city Angelenos want to live in,” he said, leading the HLA campaign and calling for this measure. said Michael Schneider, executive director of the advocacy group Streets for All, which created the idea.

The campaign has spent more than $3 million and has the support of six city councilors, business groups and trade unions. There was little financially supported opposition until the city's fire union mounted a counterattack a month ago.

Los Angeles Fire Department Local 112, which represents about 3,400 firefighters, announced it has spent $250,000 to defeat the measure.

“These street diets are delaying the response times when Los Angeles residents call 911,” said union president Freddy Escobar.

City Administrator Matt Szabo released the report a day after the fire department opposed the plan, saying the Countermeasure HLA project would cost the city $3.1 billion and force difficult budget choices in the coming years. I warned you that it would be.

Szabo estimates that bike improvements under the HLA would cost $1.1 billion, while sidewalk improvements would add $2 billion. His report said community aid could increase the bill by $80 million.

Mr. Schneider and his supporters argue that Mr. Szabo's estimates are inflated.

“I really hope voters see through this and recognize the reality of our streets,” Schneider said.

Schneider said the HLA campaign arrived at different cost estimates after obtaining records from the city's Department of Transportation and the Department of Engineering. He estimates that the ballot measure would cost $28.6 million a year if all projects were completed within 10 years. But he points out that the measure does not force that schedule.

The HLA is based on the city's 2015 Mobility Plan, but it is not yet fully realized.

Escobar said HLA designers made no attempt to meet with firefighters during development.

The measure could open the door for residents to sue if the city of Los Angeles fails to implement the plan. Authorities will need to create a website where residents can track progress and make the process more transparent.

However, even if this measure were to become widespread, there is no indication of how it would be implemented. Szabo said the financial burden could cause the city to delay other paving projects. Some transportation advocates also worry that the plan doesn't take into account the needs of local communities.
