These guidelines make New York the first city in the country to integrate multiple climate risks into its capital program, the largest in the country
NEW YORK––Today, Mayor Bill de Blasio announced the release of preliminary Climate Resiliency Design Guidelines, which for the first time establish citywide guidance on incorporating projected impacts from climate change into the planning, engineering, construction, and renovation of City facilities. Building on New York City’s national leadership on climate action, the Guidelines are the first of their kind to comprehensively address multiple climate risks across its capital program, the largest in the country. The Guidelines are a critical step towards integrating resiliency as a core principle in the design of City buildings and infrastructure by providing standard policy framework for incorporating forward-looking climate data into design, ultimately saving money by planning for future risks.
“New York is meeting the challenge of climate change head-on, and in the process we are building a better city,” said Mayor Bill de Blasio. “These guidelines are another national first, and will make the city’s buildings and infrastructure more resilient in the face of rising seas, extreme heat and storms. Our forward-looking approach will help us prepare for the effects of climate change, so the next generation can continue to call New York home.”
Led by the Mayor’s Office of Recovery and Resiliency, the Guidelines provide architects, engineers, planners, and other professionals with step-by-step instructions on how to incorporate anticipated changes in temperature, precipitation, and sea levels into the design of City facilities, based on the best available science provided by the New York City Panel on Climate Change. The Guidelines are to be used throughout the design process—from the conceptual phase to final design—for all new construction and substantial improvements of City buildings and infrastructure. Utilization of the Guidelines will result in enhanced standards that will make our built environment more resilient to extreme weather and climate change while promoting the health, safety, and prosperity of all New Yorkers.
Current building codes and standards incorporate historic weather data without accounting for changing climate conditions, such as the frequency of future floods, heat waves, and precipitation. These Guidelines provide a standard methodology for choosing design parameters from among the range of climate projections when designing resilient facilities.
Highlights of the Guidelines include:
The Guidelines were developed based on the New York City Panel on Climate Change’s regional climate projections that inform City resiliency policy. Composed of leading scientists, the NPCC prepares projections for the City and metropolitan region which have shown that extreme weather will increase in frequency and severity, and that the climate will become more variable. Climate projections encompass a wide range of possible outcomes, for example:
The NPCC continues to study and refine climate projections for the metropolitan region, and these Guidelines will be updated as new reports are released by the NPCC.
ORR worked in partnership with the NPCC and a working group of City agencies to develop the Guidelines. The City will review and pilot the Guidelines on projects throughout the rest of 2017. The results will be used to refine the preliminary draft and a final version will be released in December 2017.
These NYC Climate Resilience Design Guidelines are aligned with the Department of Design and Construction’s Guiding Principles and are meant to be utilized by agencies within their own work, such as those developed by the Department of Parks and Recreation’s Design and Planning for Flood Resiliency: Guidelines for NYC Parks. The NYC Parks guidelines are in development and will be released in 2017.
“In our OneNYC plan, we sought new ways to make our neighborhoods, economy and public services ready to withstand and emerge stronger from the impacts from climate change,” said First Deputy Mayor Anthony Shorris. “To do this, we need to integrate climate-smart thinking across the work of all City agencies. The release of these design guidelines brings us closer to building a more just and resilient New York City for all."
“Climate change is an existential threat to our city and our planet. As we continue to invest in climate adaptation across our entire $20 billion resiliency program, we are finding ways to make our investments stretch further to buy down risk for the benefit of all New Yorkers,” said Daniel Zarrilli, Senior Director for Climate Policy & Programs and the Chief Resilience Officer in the Mayor’s Office. “These design guidelines are a critical way that New York City will institutionalize the work of resiliency into the ways we design and build our infrastructure, leveraging our existing spending to ensure that we are continuing to build a more resilient city.”
“New York can no longer look to the past for how we build for the future. Extreme weather and a changing climate threaten the City buildings and infrastructure that provide critical services that New Yorkers depend on,” said Jainey Bavishi, Director of the Mayor’s Office of Recovery and Resiliency. “The Climate Resiliency Design Guidelines provide clear, accessible guidance on how to incorporate forward-looking climate data into the design of City facilities to ensure they are prepared to withstand the impacts of climate change and can continue to keep our city safe and strong into the future.”
“As a nation-wide leader in planning and development, New York City is preparing for the effects of climate change by establishing a strategy to build stronger and smarter,” said NYC Parks Commissioner Mitchell Silver. “As we face rising sea levels, unpredictable weather patterns, and more severe storms, our City – and in particular our 160 miles of shorefront parkland -- will be built to last, and to protect our communities.”
“As a coastal city, New York must be prepared for a changing climate and these new guidelines offer a roadmap as we plan for the coming decades,” said DEP Acting Commissioner Vincent Sapienza. “New York City already has the largest and most aggressive green infrastructure program in the nation, we are expanding our award-winning Bluebelt program and are engaged in a comprehensive upgrade to the City’s vital wastewater systems to ensure they are resilient against rising sea levels. All of this work will help ensure that we leave a strong and just city to the next generation.”
“The Department of Design and Construction (DDC) previously made resiliency one of the Guiding Principles it follows when designing and building public structures of all types, and we were very pleased to share our experience with resilient design as part of the working group that developed these new strategies,” said DDC Commissioner Feniosky Peña-Mora. “It’s critical that the City prepare for climate change now by ensuring that the capital projects we invest in are built to manage rising sea levels and more frequent storms.”
“Climate change poses risks to people and infrastructure in the New York metropolitan region. The Climate Resiliency Design Guidelines are a great example of how New York City is leading the charge on climate by using science-informed policies to manage those risks,” said Cynthia Rosenzweig, Co-Chair of the NPCC and Senior Research Scientist at the NASA Goddard Institute for Space Studies and Columbia University’s Earth Institute, Center for Climate Systems Research.
“Climate change requires a flexible adaptation approach to increasing climate risk. The Climate Resiliency Design Guidelines help create the managerial and operational protocols needed to better respond to these emerging shifts in the city's environmental baseline,” said William Solecki, Co-Chair of the New York City Panel on Climate Change and Professor, Department of Geography.
