Report Examines the Challenges and Costs of Building Resilience Against Climate Threats in New York
July 16th 2014
Barriers to implementing retrofits could threaten city's supply of affordable housing;
Building owners face difficult choice between up-front costs of retrofit investments or escalating flood insurance costs.
New York, NY: A new report released today by the NYU Furman Center examines the challenges of retrofitting New York City’s multifamily housing stock against future climate threats, including the potential effect on the city’s limited stock of affordable housing.
The report, The Price of Resilience: Can Multifamily Housing Afford to Adapt? (PDF), was released today after months of collaboration with government officials, architects, engineers, and housing policy experts. Focused on the challenges facing multifamily buildings, the report details design solutions and offers policy recommendations for city officials and the Federal Emergency Management Agency (FEMA) that may help remove barriers to achieving long-term resilience in this stock. The project was conducted in partnership with Enterprise Community Partners and the New York Chapter of the American Institute of Architects.
“Storm-proofing a dense, older city like New York poses unique challenges,” said Jessica Yager, Policy Director at the NYU Furman Center and co-author of the study. “Over 90% of the multifamily buildings in areas vulnerable to flooding were built prior to 1983 when flood-resistant construction standards were added into the building code, so we are faced with the challenge of retrofitting older buildings, rather than only tightening standards for new construction.”
The Price of Resilience (PDF) report details how much of the national guidance on retrofitting residential properties is geared towards 1-4 family buildings, reflecting the national housing stock. But FEMA’s new flood insurance maps place nearly 5,000 multifamily buildings—housing 170,000 units—in New York City’s 100-year floodplain.
New York City’s extreme shortage of affordable housing may also make the direct and indirect costs of retrofitting particularly hard to bear. According to the report, the majority of units in flood-prone areas are either rent-stabilized or receive a government subsidy to provide affordable housing.
“The majority of privately-owned, multifamily rental buildings in the floodplain have rents that are regulated through a subsidy program or through New York’s rent stabilization law,” said Yager. “Thus, some resiliency measures, such as eliminating units below the predicted flood level, could result in the loss of thousands of units of affordable housing.”
Even without the potential for a loss of units, a building’s location in the flood zone could also serve as a threat to affordability because of recent changes in flood insurance rules. Property owners in the 100-year floodplain face the difficult decision of bearing the burden of making costly retrofit improvements, or facing skyrocketing flood insurance premiums in the coming years if their properties do not meet certain design standards.
“Buildings with regulated rents will have a particularly hard time implementing resilience measures to protect themselves from future storms,” said Yager. “But if they do not take protective measures, they may face dramatically rising insurance premiums and potentially unsafe conditions, situations that could lead to unsustainable operating costs or, in some cases, pressure to convert to market-rate.”
The Price of Resilience (PDF) report concludes by suggesting local and national policy reforms that may help multifamily buildings achieve long-term resilience, including:
FEMA should modify the guidelines for its National Flood Insurance Program to provide more guidance to multifamily buildings, and it should explore providing partial insurance rate reductions for partial mitigation efforts.
New York City should consider expanding the zoning changes it passed after Superstorm Sandy in the 100-year floodplain to cover buildings in the 500-year floodplain.
New York City should revisit its existing rehabilitation subsidy programs to ensure that resilience measures can be readily funded; and it should require that buildings in the 100- and 500-year floodplains that it assists have adequate emergency and resilience plans.
“As New York City adapts to the growing risks it faces from climate change, FEMA must also adapt to better address the risks and needs of multifamily buildings in urban areas. Policy makers must ensure that vulnerable multifamily buildings do not get left behind,” said Yager.
In conjunction with the release of the report, the NYU Furman Center is hosting an exhibition presented in partnership with AIANY and Enterprise Community Partners. Affording Resilience: Housing Retrofits for Climate Threats will be on exhibition at the Center for Architecture through August 7, 2014. Learn more at cfa.aiany.org.
