Vision 4 Goal
The City continues to address Hurricane Sandy’s impacts on our infrastructure, protecting our power, transportation, and water systems, while also addressing emerging risks, like extreme rainfall, through resilient design.

Invested or leveraged over $11.6 billion with partners to strengthen and adapt the region’s infrastructure
Across the five boroughs the City and its partners have upgraded and hardened infrastructure systems—including transportation, water, waste, sewer, energy, and telecommunications. These investments ensure that vital public services will continue during and after emergencies. In 2017, the City and its partners focused on testing strategies to manage precipitation and extreme rainfall events, refining new standards for the design of climate-ready capital projects, and addressing climate risk factors for power generation and the energy distribution system.
Improved the City’s ability to manage and treat stormwater, including during extreme weather
In October 2013, DEP completed the NYCDEP Wastewater Resiliency Plan, which evaluated flood vulnerabilities, likelihoods and impacts of failures, and appropriate adaptation strategies for much of the City’s wastewater infrastructure. Eight projects from DEP’s Wastewater Resiliency Plan have been initiated as part of a $161 million portfolio to floodproof critical equipment at treatment facilities by implementing a combination of the following adaptation strategies: installing permanent and/or temporary barriers, sealing buildings, elevating or floodproofing critical equipment, and installing backup power systems.
DEP has been working with partners at the Department of Transportation, the Department of Design and Construction, and the New York City Housing Authority to initiate design of two pilot cloudburst resiliency projects leveraging a partnership with the City of Copenhagen. These projects will help manage extreme rainfall events in St. Albans and the South Jamaica Houses by capturing 2.3 inches of rainfall per hour. The project provides a proof-of-concept for using green infrastructure to mitigate the effects of cloudbursts and will help reduce nuisance flooding in Southeast Queens while enhancing the local landscape.
Approximately one third of Staten Island’s land area is served by its Bluebelts, which are composed of networks of streams, wetlands, and other natural features to filter and help manage storm water before it reaches the harbor. In 2017, DEP completed the largest ever expansion of the Bluebelt system with the addition of the Sweet Brook Bluebelt, serving the Woodrow area. This project added more than three miles of storm sewers, installed hundreds of catch basins, and replaced existing water mains, which will help better manage precipitation and reduce localized flooding.
Released Climate Resiliency Design Guidelines to provide a new standard for the design of City capital projects
In April 2017, the City released Preliminary Climate Resiliency Design Guidelines (CRDG) to ensure that future capital investments, both new construction and retrofits, are designed to withstand hazards in a changing climate. Since then, the City has embarked on a rigorous testing period to vet the CRDG and determine how the design of buildings and infrastructure can best reflect projected data on extreme heat, intense precipitation, sea level rise, and storm surge. In April 2018, the City will release version 2.0 of the CRDG, updated to reflect lessons learned from this assessment period. The updated version will also include a methodology for how to conduct a benefit-cost analysis that accounts for climate-related hazards and resilient design investments. The guidelines reflect the City’s commitment to developing a strong, safe, and durable built environment able to withstand extreme weather and reliably serve New Yorkers, now and into the future.
Protected the city’s utility infrastructure from storms
As part of the 2016 National Grid rate case proceedings, the City successfully advocated for a storm hardening collaborative, which began work in 2017. The collaborative’s final recommendations focus on three main asset types—the LNG plant, distribution mains, and regulator and transfer stations—and include changes to siting and risk assessment procedures, prioritizing the replacement of leak-prone pipe in the floodplain, and flood design guidance to elevate critical components of priority regulator stations located in the current and future floodplain. By January 2019, the Collaborative will reconvene to review final analyses and mitigation strategies, as well as cost estimates to make a final determination regarding necessary capital investments.
Since 2013, Con Edison has invested over $1 billion in storm hardening measures for its electric, gas, and steam systems. As part of this effort, through 2017 over 140,000 overhead system outages have been avoided in New York City.
Moving forward, Con Edison will continue to design and construct equipment in flood-prone areas to meet or exceed the standard of FEMA’s 100-year flood level, plus three feet to account for sea level rise. All new underground equipment installations and replacements of existing equipment will be of the flood-ready submersible type, where possible.
