Pasadena is quitting its plan to put Orange Grove Boulevard on a so-called “road diet.”

The plan would have converted a 1.8-mile stretch between Allen and Sierra Madre Villa avenues from its current four-lane, vehicle-oriented layout to a “complete street” — removing two lanes to slow vehicle traffic to more equitably consider the safety and movement of pedestrians, bicyclists and motor vehicles. It also called for enhancing crosswalks and adding a bike lane.

The City Council on Monday voted unanimously to ax the plan in a victory for the 500 residents who formed a group they call Keep Pasadena Moving to fight the project and a loss for groups like Pasadena Complete Streets Coalition. A lack of consensus driven by the vocal pushback from Keep Pasadena Moving were among the reasons elected officials decided to end the plan.

“It’s not a matter of winning or losing, though clearly you’ve won,” Mayor Terry Tornek said to residents who gathered with signs that matched the ones planted in their Orange Grove Boulevard front yards at the Monday meeting.

But a win for those neighbors is a loss for those who don’t rely on a car to travel and a loss of safety for all, said David Azevedo of the Complete Streets Coalition.

“The fact the council shot down fact-based, evidence-based road diets — safety plans that are being used across the country to make roads safer — we’re disappointed,” he said.

During the last 10 years, the city estimates there have been 418 traffic collisions on Orange Grove Boulevard east of Lake Avenue, resulting in 309 injuries and three deaths.

A 2010 traffic study the city commissioned found that vehicle flow would worsen by an “insignificant amount” with a lane reduction while improving pedestrian and bike movement. But neighbors still stood firm in their concern that the road diet would cause significant delays on Orange Grove and lead to motorists taking side streets to avoid the thoroughfare.

More recently, a feasibility study conducted this year found motor vehicle travel time between Lake and Sierra Madre Villa avenues would increase between 1 minute, 5 seconds and 1 minute, 45 seconds, depending on time of day and which direction the vehicle is traveling.

The report also said officials expected “minimal” amount of drivers would use side streets to avoid Orange Grove Boulevard — especially because alternative routes along those streets would take longer.

The road diet plan would have reduced crashes between 11 and 59 percent at key intersections, according to the report.

Frank Duerr of Keep Pasadena Moving lauded the council for listening to the residents’ concerns, which he says just make sense in a city where many people travel by car. “KPM is for common-sense solutions to transportation safety issues in Pasadena,” he said.

City staffers recommended ditching the plan because of their perception the community would be unable to find a compromise, a lack of funding for options other than the road diet and the fact that the city would be better served by focusing on more pressing projects.

“We’re unlikely to achieve consensus,” City Manager Steve Mermell said. “This is not to say reconfiguration of our streets is something we shouldn’t do.”

Azevedo said the city missed out on the chance to find common ground — there were a series of community forums planned in the coming months to workshop this matter.

The road diet plan has been in Pasadena’s plans since 2012 and only moved forward earlier this year after the state’s gas tax hike provided money. Nearly everyone, including city officials, agree that means the process was too rushed given the short timeline.

Pasadena’s 2015 general plan, its blueprint for growth and development, called upon officials to encourage walking, biking, transit and other nonmotor vehicle modes of transit and to design streets so that those modes of transportation are safer and more accessible — meaning the topic of road diets may reappear in Pasadena.

“We have tons of residents who don’t use a car day-to-day,” said Councilman Tyron Hampton, who represents Northwest Pasadena. “I do want to make sure those voices are being heard and there is some sort of agreement that we can come to where our city is more walkable or a more bike-friendly city, just as a whole.”
