Vision 4 Goal

Coastal Defense

Artboard 4

Since 2015, the City has advanced numerous coastal defense projects from initial feasibility analysis, through conceptual design, and toward final design and construction. In coordination with community stakeholders, the City has sought to deliver cutting-edge flood risk mitigation solutions that are integrated into the urban fabric of our neighborhoods and provide co-benefits such as recreational space wherever possible.

Invested or leveraged over $3.7 billion for coastal protection since 2015

 

The City is advancing a portfolio of unprecedented projects citywide to mitigate the risk of coastal storms and sea level rise. Major project milestones continue to be met, including the completion of the Rockaway Boardwalk and interim flood protection measures. Throughout this process, the City is engaging New Yorkers to identify and implement locally tailored resiliency solutions.

 

Committed $145 million for new and upgraded parks and facilities to protect the Rockaways from coastal storms and flooding

 

On the fifth anniversary of Hurricane Sandy, the City announced $145 million in funding for seven resiliency projects that will help protect communities in the Rockaways from future flooding and coastal storms. This funding was made available through FEMA’s 428 Program, which will capture and repurpose the City’s cost savings from the $480 million Rockaway Boardwalk reconstruction. Identified through extensive consultation with Rockaway residents, the seven projects are Bayswater Park, Shore Front Parkway Recreation Zone, Rockaway Community Park, Beach 88th Street Park, Thursby Basin Park, NYC Parks Operations Headquarters for the Rockaways and Broad Channel, and Edgemere Drainage Infrastructure.

 


Achieved major milestones on coastal resiliency projects in Lower Manhattan

 

Over the past three years, the City has made significant strides toward the implementation of the first phase of its coastal protection plan for Lower Manhattan. This has been possible due to the strong degree of cooperation and interagency coordination at all levels of government, as well as the continued focus on and investment in these projects by community stakeholders.

East Side Coastal Resiliency (ESCR)
ESCR will benefit thousands of public housing and other residents of a particularly vulnerable part of Manhattan, and will demonstrate a new model for integrating coastal flood damage mitigation into neighborhoods. In 2017, the City committed additional funding to the project, increasing the budget from $335 million to $760 million. In 2018, the project received an Action Plan Amendment approval from the U.S. Department of Housing and Urban Development (HUD) and completed preliminary design.

Lower Manhattan Coastal Resiliency (LMCR)—Two Bridges
In 2016, HUD awarded the City $176 million for the Lower Manhattan area that extends from Montgomery Street to the Brooklyn Bridge. To support this work, the City added $27 million in funding for a total project budget of $203 million. The City is currently advancing the conceptual design and feasibility analysis for the project.

Lower Manhattan Coastal Resiliency (LMCR)—Manhattan Tip
In 2015, the City allocated $108 million in funding to protect the Manhattan tip, with $8 million set aside specifically for the Battery. Work has progressed on concept designs for risk reduction projects in this area. A long-term study of climate risks in the 2100s has also been initiated, which looks comprehensively at the impact of storm surge, sea-level rise, groundwater table rise, increased precipitation, and extreme heat. Most recently, the City has engaged New York City Emergency Management (NYCEM) to assess the viability of an Interim Flood Protection Measures project (IFPM) in the Seaport district.


Reduced flood risk at 40 facilities and in Red Hook

 

Since the summer of 2015, NYCEM and the Mayor’s Office of Recovery and Resiliency (ORR) have led a program called Interim Flood Protection Measures that aims to protect, on an interim basis, neighborhoods and critical facilities from low-level, high frequency coastal flooding until larger, more permanent flood mitigation projects are completed. Working with an interagency team, NYCEM has identified, designed, permitted, and operationalized flood risk reduction solutions at over 40 City facilities and in one neighborhood. Solutions are composed of off-the-shelf flood control products, including HESCO barriers (large, sand-filled geotextile containers), Tiger Dams (long tubes filled with water), and flood panels (stackable barriers that can be used to close doorways and other openings in the event of a flood).

The City has made significant progress in advancing the reduction of flood risk in Red Hook, Brooklyn, while also maintaining the unique waterfront character of this historic neighborhood. The Red Hook Integrated Flood Protection System (IFPS) is a $104 million coastal flood mitigation initiative that reduces flood risk from lower intensity, higher frequency storm surges. The proposed project is completely passive, fully integrates into the urban fabric of Red Hook, and allows for future adaptation to higher flood elevations. The City has submitted the project concept and feasibility analysis to FEMA for approval and will advance design and construction upon approval.

The American Council of Engineering Companies of New York has awarded the Red Hook Integrated Flood Protection System Feasibility Study a 2018 Engineering Excellence Platinum Award.
