PlaNYC – Climate Resiliency Design Guidelines
New York City Panel on Climate Change, Mayor’s Office of Recovery and Resiliency
A successful resiliency strategy is one that provides co-beneficial outcomes, reduces costs over the life of the asset wherever possible and avoids negative indirect impacts to other systems. Resilient design should not exist in a silo, but rather be a well-integrated part of existing processes and address other goals of the city.
The city is working to reduce its contribution to climate change by following the PlaNYC goal of cutting back greenhouse-gas emissions by 30 percent by 2030. In 2017, Mayor Bill de Blasio announced the release of the preliminary Climate Resiliency Design Guidelines, which for the first time established city-wide guidance on incorporating projected impacts of climate change into the planning, engineering, construction, and renovation of city facilities (infrastructure, landscapes, and buildings). The guidelines were developed based on the New York City Panel on Climate Change’s regional climate projections that inform the city’s resiliency policy. The primary goal of the guidelines is to incorporate forward-looking climate change data into the design of all city capital projects and thereby create a resilient facility design. Therefore, facilities have to be designed in a way to withstand or recover quickly from natural hazards as well as to perform to their design standard throughout their useful life in a changing climate. To support the development and selection of climate-resilient designs, the Guidelines recommend design adjustments or interventions in response to increasing heat, increasing precipitation, and sea level rise.
