OneNYC 2018 Progress Report

One New York: The Plan for a Strong and Just City (OneNYC), is the City’s strategic plan for population growth, sustainability, equity, and climate resilience. In 2015, New York City committed to becoming the most sustainable big city in the world, and a global leader in mitigating and adapting to climate change with this plan. The 2018 Progress Report details many achievements across all categories of OneNYC in the last three years, including a number of projects and strategies aimed at climate resilience. 

Since 2015, New York City is becoming more resilient, citing some indicators of success related to city assets, such as:

  • Updated building and zoning codes have been implemented for resilience.
  • Infrastructure “is stronger, including upgraded traffic infrastructure, hardened telecommunications systems, and fortified wastewater treatment plants, all of which ensure that critical services continue during and after emergencies.”

The OneNYC Resiliency chapter is, in part, focused on climate change impacts including sea level rise, increased temperatures and precipitation, and a growing likelihood of more intense storms. Progress has been made to address these impacts, including:

  • Coastal protections were integrated in the construction of a new Rockaway Boardwalk, and nearly ten miles of new dunes across the Rockaway Peninsula and in Staten Island have been implemented for coastal resiliency.
  • The NYC Department of Environmental Protection (DEP) is investing billions of dollars to upgrade the wastewater collection system to ensure that the maximum amount of wastewater receives treatment during storms.
  • The city launched a comprehensive $106 million heat mitigation and adaptation program for managing extreme heat events.

Additionally, New York’s green infrastructure program is expanding:

  • Over 620,000 trees were planted in New York City, transforming the landscape with new street trees, new trees in parks and natural areas, and through the installation of green infrastructure projects citywide.
  • The report states that by the end of 2017, nearly 4,000 green infrastructure assets were constructed or are in construction across the city, in addition to other forms of green infrastructure located in City parks, playgrounds, schools, and housing developments.
  • In 2017, DEP also completed the installation of 40,000 oysters in Jamaica Bay - to help filter pollutants from water, help protect wetlands and shoreline from erosion and storm surge, and provide habitats for communities of fish and other aquatic organisms.
