Mayor Martin J. Walsh is planning to jack up parking fines to pay for $5 million in traffic projects — with $1.4 million going to pay 19 new employees — and city officials say residents are demanding the increase in enforcement for residential parking violators and other scofflaws.

Walsh’s plan would hike fines in numerous areas — “no parking” zone tickets would jump from $55 to $90 and “double parking” tickets from $45 to $75 downtown, while no-parking violations in the rest of the city would increase from $25 to $55 and double-parking tickets from $30 to $55.

Residential parking violations would increase from $40 to $60, and all parking meter tickets would rise from $25 to $40. The city would also stop towing for overnight street cleaning, but increase that ticket from $40 to $90.

Officials expect to collect an additional $5 million from the new fines, which Walsh wants to use for projects including $2 million in road and sidewalk repairs and $300,000 in bike lanes. The money will also go to 19 new employees, including a new parking enforcement supervisor, a number of signal maintenance workers and planners, and a five-member “Transit Team” working with the MBTA to improve service.

But city Chief of Streets Chris Osgood said the city’s parking enforcement plan is not directly tied to the projected $5 million in new revenue and officials would not issue more tickets if funds were falling short. He said residents are demanding more enforcement, with 311 calls about resident-sticker zone violations “skyrocketing” from 4,100 in 2014 to more than 35,000 last year.

“We wanted to re-look at parking fines to address the chronic challenges residents are asking us to address. … We expect a positive change on our streets,” Osgood said.

Transportation Commissioner Gina Fiandaca said the new parking supervisors help increase enforcement, particularly in residential neighborhoods.

“We do get calls for enforcement out in our neighborhoods that we don’t have the capacity to respond to in a very efficient manner at this time, having that additional capacity will certainly serve the community well,” Fiandaca said.

The City Council has to approve any parking fine changes, but At-Large Councilor Michelle Wu, a longtime transportation advocate, said the increases were fair and would help pay for other improvements.

“People don’t believe enforcement is at the level it needs to be, residential parking is being taken up by folks who don’t have the appropriate permits,” Wu said. “People want the rules to be followed — you’re not required to pay an increased fine, you just have to follow the rules.”
