City parks officials are planning a $3.5 million restoration for a swath of the Boston Common where the sidewalk is buckling, bricks are missing, and an aging trio of bronze statues have not had any TLC for years.
Parks Commissioner Christopher Cook promised a top-to-bottom redo of the Parkman Plaza, a dreary patch of the nation’s oldest public park. It includes the paved semicircle that is home to the visitor information center, where at least 500,000 tourists stop by each year seeking guidance to the city’s popular sites.
Cook said the department expects to start work this year, beginning midway down Tremont Street. Next year, the focus will be on the Boylston Street side, nearest to Tremont — a short walk from the Park Street station entrance on the Red Line down to AMC Loews theater near the edge of Boylston Street.
“The Common has suffered from a lack of investment in infrastructure,’’ Cook said. “Certain conditions that we take for granted in other public spaces have been left by the wayside for a long time. This will help the park function better and change people’s perception of it.”
Over the past two years, city officials conducted a study, interviewed people, and consulted with various groups — including the Greater Boston Convention & Visitors Bureau, Freedom Trail Foundation, and the city’s Landmarks and Art commissions — to gain a better understanding of how the space was being used. They wanted to know what was working well, and what wasn’t.
The city is planning $3.5 million in repairs to a stretch of the Tremont Street side of Boston Common, from the area in front of the visitor information center to Boylston Street.
They determined that while the space was frequently used by tour groups and tourists, it was in poor condition.
“The paving, the benches, the flagpoles suffered through the years,’’ said Margaret Dyson, Boston’s director of historic parks.
Dyson said that when completed, the newly renovated section of the park will be outfitted with new seating, a new entrance to the visitor’s center, and improved space for tour groups.
“It will feel like an entirely refreshed space,’’ she said, “and it will feel like it makes sense for Boston Common.’’
Cook outlined the improvements in his department’s five-year capital plan, which was included in Mayor Martin J. Walsh’s proposed budget. The City Council’s Ways and Means Committee is combing through the budget before bringing it to the full legislative body for a final vote in June. The Boston Landmarks and Art commissions must also approve.
The planned improvements are part of the city’s long-term strategy to revitalize the aging Common, which spans nearly 50 acres. The city is also targeting other treasured open spaces, including Franklin Park.
The capital plan calls for spending $1.51 million on pathways and other improvements in Franklin Park, which borders Jamaica Plain, Roxbury, and Dorchester. Cook is also seeking more accessibility for the disabled at the city’s other parks.
Other efforts to boost Boston Common were undertaken by developer Millennium Partners, which is building in Downtown Crossing. Around 2000, the developer spent $1 million to erect a fence and restore the side of the park along Boylston and Avery streets, said Joe Larkin, a principal at the company.
Back then, Larkin said the company also promised to donate $50,000 annually to the Parks Department for 20 years and has kept its pledge.
The latest planned renovations of the Common follow work completed in recent years closer to the Park Street side.
In the past five years, the city spent $783,000 on improvements on Boston Common. The costs include $133,000 for repairs at the Soldiers and Sailors Monument, and $600,000 to restore the deteriorating Brewer Fountain, a one-of-a-kind bronze sculpture created for the 1855 World’s Fair in Paris and donated to Boston by Beacon Hill merchant Gardner Brewer, according to Friends of the Public Garden.
Another $600,000 targeted repairs on the Common, the Public Garden, and the Commonwealth Avenue Mall, parks officials said.
Initially installed near the Beacon Street side of the Common in 1868, Brewer Fountain was moved in 1917 to its current location, near Tremont and Park streets.
To complement the fountain’s renewal, Friends of the Public Garden, which raises money and works to preserve the city’s first parks, launched a $4 million privately funded effort, beginning in 2011, to revitalize the area around it, up to the State House.
That section of the park now boasts cafe-style tables shaded with linen-colored umbrellas, a rolling reading room stocked with magazines and books, and summer jazz concerts.
New trees, restored turf, pathways, and curbing were installed, along with a historic iron fence.
Elizabeth Vizza, executive director of Friends of the Public Garden, said the Boston Common improvements have been a long time coming.
“This next piece is critical to keep that momentum going and keep construction going,’’ Vizza said. “It’s our front door to the world. Many people come here to visit. And it’s really important to have a good-looking front door.”
Dyson, the director of historic parks, said the planned Common project is costly because the area sits atop the subway, and special care is needed to ensure a smooth reconstruction.
“That part of the park appears to date to 1959, in terms of the furnishing and the surfacing of the park,’’ Dyson said. “They are beyond their useful life and need to be replaced.”
Parkman Plaza, dedicated in the 1960s, is adorned with bronze statues by sculptor Adio diBiccari and his brother-in-law Arcangelo Cascieri. The near life-sized statues represent Boston’s intellectual, spiritual, and industrial life, according to the Boston Art Commission. One clutches a book, another a jackhammer, and a third kneels with palms outspread as if in prayer.
