The Back Bay is getting a long-awaited update to its parking distribution, adding over a hundred residential spaces and removing just as many meters.

City workers have begun uprooting outdated parking infrastructure across the neighborhood, altering almost 300 spaces to reflect changes in the streetscape. It marks the culmination of years of effort from residents and civic groups trying to get more residential parking in the Back Bay.

The Boston Guardian first reported on preliminary drafts of city plans almost a year ago in April, but parking studies and blueprints weren’t finalized and presented to the Streets Cabinet until January.

By that point the construction season had passed, forcing city workers to delay implementation until there was “appropriate seasonal weather” according to a spokesperson for the Boston Transportation Department (BTD).

By early March things had warmed up enough for crews to start their work. They’re now going block by block and replacing selected parking infrastructure with the goal of finishing by April.

That timeline could still be delayed by the weather. Even after the plan is implemented, the BTD says it will keep fielding comments from residents and potentially making alterations.

“The BTD will work with the community to address any questions or concerns and make adjustments if needed over the coming months,” said a spokesperson.

A total of 281 parking spots are being changed, with 125 meters removed and the largest portion being converted to residential parking. The 123 spots reserved

for residential permits are mostly on Beacon Street, with some on Commonwealth Avenue and a few on Marlborough Street.

Residential permits will also grant access to overnight parking in 25 spaces from 6pm to 8 am. Another 78 existing meters will have their hours extended from 8am to 8pm Monday-Saturday.

Businesses and deliveries also get a nod with 60 spaces of 30-minute metered parking. Beacon Street and Commonwealth Avenue are both getting a smattering of those, though Marlborough Street will have only 3 around Berkeley and Clarendon Streets.

The changes aim to update the parking map so that residential parking is plentiful on residential streets and commercial parking follows suit.

Changes to parking maps come slowly, and in the Back Bay there are plenty of metered spaces that were created years ago for businesses and civil organizations that no longer exist, replaced today by residences.

The gap between city government and changing real estate trends exacerbates the disparity between the number of residential parking permits and actual residential spaces, which was estimated by the Neighborhood Association of the Back Bay to be around 3:1 in 2021.
