Standing in High Bridge Park in the Bronx, against a backdrop of the city’s oldest bridge and the bare trees of a neighborhood long neglected by City Hall, Mayor Zohran Mamdani on Saturday appointed Tricia Shimamura as the city’s next Parks Commissioner.
The selection of Ms. Shimamura, a veteran social worker and the former Manhattan Borough Commissioner for the Parks Department, marks a significant step in Mr. Mamdani’s efforts to transform his insurgent, democratic-socialist campaign promises into the granular reality of municipal governance. For a mayor who campaigned on the idea that the “urban commons” are as vital as housing and transit, the appointment is a signal that his administration intends to treat the city’s 30,000 acres of parkland as a cornerstone of his affordability agenda.
“In a city where almost everything costs something, our parks are the rare corner that are truly accessible and affordable to each and every person,” Mr. Mamdani said, quoting both Frederick Law Olmsted and the rapper MC Shan to illustrate the role of public space in New York life. “And yet, for too long, they have been the first victims of cuts—the public infrastructure most eagerly sacrificed.”
A Test of the ‘1 Percent’ Promise
The appointment puts Ms. Shimamura at the center of one of Mr. Mamdani’s most specific and closely watched campaign pledges: earmarking 1 percent of the total city budget for the Parks Department.
During the 2025 race, Mr. Mamdani frequently attacked the previous administration for failing to reach that threshold, a goal long sought by advocacy groups like New Yorkers for Parks. Currently, the department receives approximately 0.6 percent of the city’s budget. Reaching 1 percent would mean an infusion of hundreds of millions of dollars, which Mr. Mamdani has said would be used to end hiring freezes, repair crumbling bathrooms, and prioritize “environmental justice” in neighborhoods with high heat indexes and low canopy cover.
Ms. Shimamura, 38, seemed to embrace this mandate on Saturday, calling Parks the “agency of affordability.”
“We will hold every park to the same level of significance as we would our own backyard,” she said, “because we know that for millions of New Yorkers, that’s exactly what they are.”
Identity and the Progressive Pipeline
The choice of Ms. Shimamura also reflects the Mayor’s penchant for appointees whose personal biographies mirror his administration’s focus on marginalized histories. Mr. Mamdani noted that Ms. Shimamura is the granddaughter of Japanese Americans who were interned during World War II and of Puerto Rican grandparents who worked in Brooklyn garment factories.
Her background as a social worker, a profession she shared with the Mayor’s new Chief Equity Officer, Afua Atta-Mensah, is no coincidence. The Mamdani administration has moved away from the traditional “managerial” class of commissioners, favoring leaders with experience in community organizing and direct service. Before joining the Parks Department in 2024, Ms. Shimamura served as a deputy chief of staff to former Representative Carolyn Maloney and as a director for the current Comptroller, Mark Levine.
The Challenges Ahead
While the appointment was met with praise from park advocates, Ms. Shimamura faces an immediate test of her political and administrative mettle. The Mayor’s broader fiscal strategy involves significant tax increases on high earners to fund fare-free buses and rent freezes which are proposals that have already met resistance from the state legislature and business leaders.
If the city faces a budget shortfall, the “1 percent for parks” pledge could become a target for more traditional fiscal hawks. Furthermore, some of Mr. Mamdani’s other campaign ideas including building 100 percent affordable housing on underutilized public land, could potentially put the Parks Department in the middle of heated “green vs. gray” land-use battles.
In his first few weeks, Mr. Mamdani has moved with a speed that has startled both his supporters and his critics. From creating a task force to identify city land for housing to installing the tenant advocate Cea Weaver as the city’s “tenant-in-chief,” the new Mayor is clearly in a hurry.
On Saturday, as the wind whipped through the Bronx, he made it clear that he views the state of the city’s grass and playgrounds as a barometer for his success.
“We are pursuing a city where a dignified life is available to every New Yorker,” the Mayor said. “And we will find that purpose in the places where everyday people go to find peace of mind.”
