Mayor Zohran Mamdani signed two executive orders at City Hall on September 4, pairing a new annual September 11 remembrance initiative with a substantial rewrite of New York City’s continuity-of-government and emergency preparedness framework.
The first order, Executive Order 21, formally designates September 11 each year as a Citywide Day of Remembrance and Service. The second, Executive Order 22, replaces the city’s 2007 Continuity of Operations framework and creates a new senior-level interagency body responsible for keeping essential city services functioning during emergencies.
The video released by the Mayor’s Office shows Mamdani presenting the measures alongside senior officials from FDNY, NYPD, NYC Emergency Management, DCAS, OMB and the Office of Technology and Innovation. The machine-generated transcript supplied with the video accurately captured the substance of the event, although it contained recognition errors in several names and acronyms; those details were checked against the official City Hall transcript.
September 11 Becomes an Annual Citywide Day of Remembrance and Service
Executive Order 21 directs the Mayor’s Office to coordinate an official city observance every September 11.
The order calls for remembrance of those killed in the 2001 terrorist attacks, first responders, rescue and recovery workers who later died from 9/11-related illnesses, survivors, families and city employees involved in the response and recovery. It also encourages city agencies to hold memorial ceremonies, moments of silence, educational programs and other commemorative activities.
The Mayor’s Office is also directed to work with NYC Service to promote volunteer and community-service opportunities.
According to the order, nearly 60,000 New York City employees participated in rescue, recovery, cleanup, medical, public health, infrastructure and related operations following the attacks.
This is not a new city holiday or paid day off. The practical effect is the creation of a permanent citywide framework for annual remembrance and service activities.
Mamdani: “Never Forget” Should Be Reflected in Action
At the signing ceremony, Mamdani linked the remembrance order to the way New Yorkers responded immediately after the attacks.
He described residents donating blood, bringing supplies, helping strangers and participating in recovery efforts. He said the city would use the annual observance to preserve that tradition of service for future generations.
The remarks are significant primarily as an explanation of the administration’s policy rationale. The legally operative provisions are contained in the executive orders themselves.
A Much Larger Administrative Change Is Contained in Executive Order 22
The second order is more consequential for the day-to-day operation of city government.
Executive Order 22, titled “Safeguarding New York City’s Essential Services,” revokes Executive Order 107 of October 2, 2007 and establishes an updated framework for Continuity of Operations, Continuity of Government and what the administration calls “Mission Assurance.”
The order identifies essential services that include public safety, health, transportation, water, education, social services, administration of justice and public communications.
The stated objective is straightforward: those services should continue, or be restored rapidly, when normal city operations are disrupted.
New Continuity and Mission Assurance Team
The order creates a Continuity and Mission Assurance Team, or CMAT, chaired by the Deputy Mayor for Operations.
The team includes senior representatives from:
- NYC Emergency Management;
- Department of Citywide Administrative Services;
- Office of Management and Budget;
- Office of Technology and Innovation.
It is required to meet at least quarterly. NYC Emergency Management will serve as the lead coordinating agency for the program.
This moves continuity planning from an agency-by-agency technical exercise toward a more centralized system involving operations, technology, cybersecurity, facilities, personnel and budget planning.
Every Mayoral Agency Must Update and Test Its Plan Annually
One of the most concrete provisions of Executive Order 22 is the new compliance requirement for mayoral agencies.
Each agency must identify its essential services, maintain a Continuity of Operations plan, update that plan by December 31 every year and conduct at least one exercise annually to test it. Agencies must also designate a senior official responsible for continuity planning.
The CMAT, acting through NYC Emergency Management, is tasked with enforcing compliance with both the annual plan update and annual exercise requirement.
That creates a measurable benchmark by which the administration’s implementation can later be judged.
NYC Says It Already Maintains More Than 60 Major Continuity Plans
At the ceremony, NYC Emergency Management Commissioner Christina Farrell said the city currently maintains and exercises more than 60 major continuity plans each year.
She also said more than 140 continuity planners are working across city agencies, and that NYC Emergency Management had already supported 20 real-world continuity incidents in 2026, including snowstorms, fires and technology failures.
Those numbers come from an official statement by the commissioner during the event. They demonstrate the scale of the existing program, but they are not, by themselves, an independent performance audit.
For Midtown Tribune readers, that distinction matters: the city has documented the existence of a continuity system, while the effectiveness of the newly expanded structure will need to be evaluated over time.
The 2007 Framework Was Still Being Used
The administration’s description of the earlier system is consistent with other city records.
Before the new order, city agencies were still operating under Continuity of Operations requirements tied to Executive Order 107. A recent city job posting, for example, explicitly described responsibility for maintaining COOP plans in compliance with that order. A city cybersecurity policy likewise cited Executive Order 107 as an authority underlying continuity requirements.
That confirms that the 2007 framework was not merely historical; it remained part of current city administrative practice before Mamdani revoked and replaced it.
What Changes for New Yorkers — and What Does Not
For residents, the September 11 remembrance order creates a more visible annual civic observance, including volunteer opportunities and city-sponsored commemorative programming.
Executive Order 22 has a less visible but potentially more important effect. It changes how city government prepares to maintain essential services during disruptions such as severe weather, power failures, technology outages, building emergencies or other crises.
However, the signing of an executive order is not evidence that emergency services have already improved.
What has been established is a new governance and compliance framework. Whether it produces faster recovery, fewer interruptions or better coordination will depend on implementation, exercises and performance during actual emergencies.
A Clear Test for the Administration
The administration can therefore be evaluated against several specific promises contained in the order.
By the end of each year, mayoral agencies should have updated continuity plans. Each should conduct an annual exercise. CMAT should meet at least quarterly. NYC Emergency Management should oversee compliance.
Those requirements make Executive Order 22 unusually testable.
The question for the coming year will not simply be whether City Hall created another task force, but whether the agencies actually complete their plans, conduct the required exercises and demonstrate that essential services can continue during a real disruption.

Questions and Answers
Is September 11 now a New York City holiday?
No. Executive Order 21 establishes a Citywide Day of Remembrance and Service. It does not create a new paid municipal holiday.
What is the most significant change in Executive Order 22?
It replaces the 2007 continuity framework, creates CMAT and requires mayoral agencies to update and exercise their continuity plans every year.
What services are covered?
The order specifically references public safety, health, transportation, water, education, social services, justice administration and critical public communications.
Does the order prove New York is now better prepared for an emergency?
No. It establishes new procedures, responsibilities and oversight. Actual improvement will have to be measured through compliance, exercises and performance during real emergencies.
Why was the old system replaced?
The previous citywide continuity framework dated to 2007. The administration argues that changes in technology, cybersecurity, infrastructure and the broader threat environment require a more comprehensive system. That rationale is reflected both in the new order and the official signing remarks.
