From repairing pesky potholes to taking on a top-ten snowstorm, Mayor Mamdani's administration has made one thing clear in its first 100 days: there is no problem too big or too small for City government to solve.
Under Mayor Mamdani, the City's operational agencies - including the Department of Transportation, Department of Design and Construction and Department of Sanitation - have accelerated both rapid-response fixes and transformational projects. The focus is simple: faster, safer commutes; stronger emergency response; and a public realm that works for every New Yorker.
"There is no pothole too far, no trash pile too high and no problem too big or too small for City government to address. In our first hundred days, we've shown what it looks like when government delivers: cleaner streets, repaired roads and public spaces that every New Yorker can enjoy," said Mayor Mamdani. "The best part is the work has just begun. We are building a city where rest, movement, play and love are not luxuries but guarantees."
"This work is anchored in execution," said Deputy Mayor for Operations Julia Kerson. "Whether addressing everyday frustrations like slow buses or rising to meet extraordinary challenges like a historic snowstorm, our agencies will move deftly to keep our city running and make it better every day."
FASTER, SAFER COMMUTES
Mayor Mamdani wasted no time delivering safer streets, faster buses and more reliable commutes for New Yorkers.
At times, he took matters into his own hands.
In his first week in office, Mayor Mamdani was boots on the ground with Department of Transportation (NYC DOT) crews delivering a small-but-mighty fix for cyclists everywhere: repairing the dangerous Williamsburg Bridge bump.
Today, the Mayor picked up a shovel again - this time on Staten Island - to fill the City's 100,000th pothole, the highest number of potholes filled in the first 100 days of the calendar year in 11 years, as part of an aggressive repair campaign that has deployed 80 crews across multiple citywide blitzes, each filling a week's worth of potholes in a single day.
Since day one, the administration has restarted major projects that had stalled for years, including:
- McGuinness Boulevard redesign in Greenpoint, Brooklyn.
- 31st Street redesign in Astoria, Queens, one of the borough's most dangerous corridors.
- Madison Avenue double bus lane extension in Manhattan.
- Fordham Road Bus Lane in the Bronx's busiest bus corridor.
- Ashland Place Bike Lane on a Brooklyn block known as 'Crashland.'
- Midwood, Flatbush, and East Flatbush Bike Lanes.
- Brooklyn and Kingston Ave Bike Lanes.
The administration is also advancing new streets projects by:
- Launching engagement on the next phase of Manhattan's famously successful 14th Street.
- Breaking ground on improved Bronx crosstown bus service near Yankee Stadium.
- Preparing for the World Cup with major street upgrades, including:
- Ninth Avenue redesign in Hell's Kitchen.
- Expanded bike lanes and pedestrian spaces from SoHo and the East Village to Union Square.
- A new, dedicated bike connection to the Brooklyn Bridge's Manhattan entrance.
To tackle street safety head on, Mayor Mamdani:
- Announced the largest Sammy's Law expansion in City history, committing to 15 mph Slow Zones at every eligible school.
- Activated red light cameras - which reduce red-light running by 73%, T-bone crashes by 65% and rear-end collisions by 49% - at 250 intersections, with plans to reach all 600 intersections by year's end.
- Ended criminal enforcement for minor traffic offenses for cyclists and e-bike riders, ensuring these violations are addressed through the same civil summons process as motorists, while launching comprehensive safety training for deliver workers.
STRONGER EMERGENCY RESPONSE
Mayor Mamdani's first 100 days included the coldest feels-like temperature in two decades and a top-ten snowstorm.
During January's cold snap, Mayor Mamdani released a video PSA urging New Yorkers to sign up for Notify NYC. The response was immediate: 51,000 new subscribers joined in just one week, with more than 142,000 new subscribers so far this year - surpassing nearly all of 2025's growth in under 100 days.
Through the winter emergencies, Mayor Mamdani mobilized the City at every level:
- Coordinated dozens of agencies during the first-ever 24-hour Enhanced Code Blue.
- Opened new warming shelters, deployed warming buses and launched the City's first in-person activation of the Strengthening Communities partner network.
- Sent community partners out across all five boroughs to distribute more than 1,300 flyers in bodegas, delis, fast food restaurants and small businesses encouraging New Yorkers to call 311 for those in need.
- Deployed 6,600 sanitation workers for 41 days of 12-hour shifts clearing snow and salting streets and sidewalks.
- Expanded the Emergency Snow Shoveler program from 1,500 to more than 7,800 participants and activated Emergency Snow Shovelers earlier than ever before, clearing out snow even before snowfall ended.
The administration also introduced new tools to improve response, including a geotagged dashboard to track snow clearance at unsheltered bus stops.
The Fire Department of the City of New York (FDNY) complemented these efforts by engaging more than 53,000 New Yorkers in fire safety education and installing 4,600 smoke alarms in more than 1,300 homes.
By the end of the winter, the City had:
- Melted 783 million pounds of snow.
- Spread 1 billion pounds of salt.
- Cleared 135,000 crosswalks, 34,000 bus stops and 29,000 fire hydrants.
- Removed hundreds of downed trees.
New York City now heads into the rainy season. To begin to prepare the city, the Mamdani administration is investing $108 million to replace and upgrade more than 6,700 catch basins over the next decade and has already completed more than 350 catch basin upgrades to improve drainage and street safety.
A PUBLIC REALM THAT WORKS FOR EVERY NEW YORKER
The Mamdani administration is reimagining public spaces as essential infrastructure - expanding access, investing in long-neglected neighborhoods and opening civic assets to all.
In his first 100 days, the Mayor:
- Launched a new effort to install public bathrooms at a lower cost and on a faster timeline, beginning with a new public restroom in West Harlem.
- Announced $50 million in new capital investments to reconstruct 10 parks serving more than 116,500 New Yorkers.
- Announced the David N. Dinkins Municipal Building's tallest tower would open this June to New Yorkers and tourists after $6 million worth of renovations and repairs. Nearly 10,000 people a year will soon be able to take in views from the top of the cupola at 1 Centre Street.
- Made renting 13 iconic civic spaces more accessible through the 'Halls of the City' interactive story map.
- Opened the $141 million Shirley Chisholm Recreation Center in Flatbush, Brooklyn's largest recreation center, the first in Central Brooklyn and New York City's first completely public building to be constructed using the design-build method of contracting - which enabled the City to complete the project at least three years faster than would have been possible under the traditional system.
- Announced that five projects will proceed with similar faster Alternative Delivery methods.
- Completed the $4 million restoration of the historic Hunterfly Road Houses at Weeksville Heritage Center in Brooklyn ahead of schedule.
- Launched the City's first undergraduate scholarship program for municipal employees.
And in the final stretch of these first 100 days, Mayor Mamdani launched the first-ever Mayor's Municipal Madness - a bracket-style competition of city fixes - to spotlight and solve everyday issues raised by New Yorkers. While every problem will be solved, only one will be fixed by the Mayor on Day 100 of the administration.
New Yorkers cast more than 21,000 votes on 16 local fixes ranging from new windscreens at Staten Island tennis courts to bench repairs in Brooklyn.
On April 10, the winner will be revealed, and on April 11, the administration won't slow down tackling the problems big and small because the work doesn't stop at 100 days.
"In just 100 days, we have taken many meaningful steps to make city government more responsive for New Yorkers; whether that's through opening civic spaces to the public, delivering critical resources during extreme weather, investing in childcare and education or reaching major sustainability milestones. These 100 days are only the beginning, and we will continue building a more effective government for all New Yorkers," said Department of Citywide Administrative Services (DCAS) Commissioner Yume Kitasei.
"In the first 100 days of the new administration, DDC completed the amazing Shirley Chisholm Recreation Center three years faster than a typical project and also celebrated a unique renovation at Weeksville Heritage Center. We plan to keep delivering for New Yorkers over the next four years and beyond," said NYC Department of Design and Construction (DDC) Acting Commissioner Eduardo del Valle.
"We are strengthening our City - neighborhood by neighborhood, block by block. Our infrastructure has to work harder and smarter in the face of climate change, and DEP is committed to preparing New Yorkers for whatever storm comes next," said Department of Environmental Protection (DEP) Commissioner Lisa F. Garcia.
"The Department of Records & Information Services launched an online exhibit NYC's Story: The City on Record, illustrating 400 years of city history, introduced a new research services platform to handle more than 30,000 annual requests to the Municipal Archives and Library and welcomed 1,500 people to our public programs and facilities," said Department of Records and Information Services (DORIS) Commissioner Pauline Toole.
"In just 100 days, thanks to the talent and dedication of 6,000 NYC DOT employees, we are thinking big, aiming high and delivering real results - making buses faster, streets safer and communities more vibrant for all New Yorkers," said NYC DOT Commissioner Mike Flynn.
"The Mamdani administration has spent its first 100 days making one thing abundantly clear: New Yorkers can rely on their City to get the job done, every time. New York's Strongest are proud to be delivering on that commitment, from removing snow to cleaning up illegal dumping to just collecting the trash on time," said Department of Sanitation (DSNY) Commissioner Gregory Anderson.
"In our first 100 days, our focus has been on supporting FDNY members, strengthening our operations and continuing to protect the people of New York City. I am proud of what we have accomplished so far, and we will continue this work to build a stronger FDNY," said FDNY Commissioner Lillian Bonsignore.
"We want all New Yorkers to participate in the city's clean energy future. We are making good on that vision by deploying heat pumps to NYCHA residents, launching a challenge to develop clean-powered street vendor carts and opening new electric vehicle charging docks. This administration is taking bold steps to cut fossil fuel use and make our city cleaner and healthier. I am excited about the upcoming initiatives this administration will unveil to tackle the interconnected issues of climate and affordability," said New York City Chief Climate Officer Louise Yeung.
"Procurement should not be a barrier to delivering services - it should be an enabler, and that's the shift we're driving across the City's contracting system. In the first 100 days, we've taken meaningful steps to make that system clearer, more accessible and easier to navigate," said Mayor's Office of Contract Services (MOCS) Director and City Chief Procurement Officer Kim Yu.
"We know how small issues can become major challenges for nonprofits serving New Yorkers. That's why for the first time we're proud to include human service metrics in the Preliminary Mayor's Management Report to show the Administration's commitment to transparency. Our team has also resolved over 300 nonprofit issues in partnership with our agency Chief Nonprofit Officers to ensure providers are paid on time and can continue services without delay," said Mayor's Office of Nonprofit Services (MONS) Executive Director Michael Sedillo.
"The accomplishments of the Mamdani Administration's first 100 days show what is possible when agencies work together efficiently and effects to cut red tape and deliver for New Yorkers," said Mayor's Office of Operations Director Dan Steinberg.
"In its first 100 days, this administration has begun building a new era for emergency management, and New Yorkers are showing up to be part of it. With Notify NYC now surpassing 1.5 million subscribers, this administration is proving that no problem is too big and no problem is too small when we prepare together," said NYC Emergency Management (NYCEM) Commissioner Christina Farrell.
"Over this administration's first 100 days, OTI demonstrated its steadfast commitment to using technology to better serve New Yorkers: from providing trusted information to 800,000 NYC 311 users during the blizzard, to helping working-class families find affordable child care in their communities more easily. We look forward to building upon this early success with Mayor Mamdani's support and guidance," said New York City Chief Technology Officer and Office of Technology and Innovation (OTI) Commissioner Lisa Gelobter.
"Whether it's opening new recreation centers, quickly clearing downed trees after a major blizzard or fixing drinking fountains ahead of our busy summer season, Parks is tackling issues big and small to improve quality of life for New Yorkers. We're committed to ensuring that our parks are free, welcoming and vibrant spaces that every New Yorker can be proud of," said Department of Parks and Recreation (NYC Parks) Commissioner Tricia Shimamura.
