Population in the U.S. Floodplains
In conjunction with the launch of FloodzoneData.us, the NYU Furman Center released a series of data briefs to illustrate the housing and population located in the U.S. floodplains. The second brief in the series, Population in the U.S. Floodplains, explores the characteristics of the population located in the 100-year floodplain and the combined floodplain (100-year and 500-year floodplain), nationwide. In 2015, more than 30 million people (10% of the U.S. population) lived in the combined floodplain.

Selling the Debt: Properties Affected by the Sale of New York City Tax Liens
This data brief sheds light on the process of tax lien sales in New York City, which affected over 15,000 properties and roughly 43,600 residential units between 2010 and 2015.
It finds that most tax liens in New York City eligible for sale are sold and generate substantial revenue for the city; between 1997 and 2015, the city raised more than $1.3 billion from the sale of tax liens. However, the city also has the power to remove liens eligible for sale from the lien sale list. The report also describes the characteristics of properties with liens sold in New York City between 2010 and 2015, including the property type, their location, and the outcome following the lien sale.

Shifting the Burden
Some of New York City’s most valuable properties in its highest-cost neighborhoods are significantly and persistently undervalued, according to Shifting the Burden. The report identifies 50 individual co-ops in 46 buildings that were sold in 2012 for more than the New York City Department of Finance’s estimate of the market value of the entire building. This undervaluation has significant consequences for the distribution of tax burdens in New York City.

The Challenge of Rising Rents: Exploring Whether a New Tax Benefit Could Help Keep Unsubsidized Rental Units Affordable
The bulk of New York City’s housing stock that is affordable to low-income households is in multifamily buildings that receive no government subsidy to maintain low rents. Therefore, rising rents threaten the future affordability of this critical source of low-rent housing. The report considers whether the city could offer a benefit to protect affordability in this stock, and examines the feasibility of such a program for building owners and the city. The policy brief is third in the five-part series, Housing for an Inclusive New York: Affordable Housing Strategies for a High-Cost City. See the press release or read the key findings.

The Price of Resilience: Can Multifamily Housing Afford to Adapt?
This report explores the challenges of retrofitting New York City’s existing multifamily rental buildings to be more resilient to future storms. After summarizing our key findings, we provide background about the current regulatory requirements existing building owners who wish to retrofit must navigate. We then discuss the results of a design workshop the Furman Center convened in January 2014 with the help of our partners at the New York Chapter of the American Institute of Architects (AIANY) and Enterprise Community Partners.

Unlocking the Right to Build: Designing a More Flexible System for Transferring Development Rights
This report details the untapped potential for NYC’s transferable air rights program, a critical tool for high-density housing development in New York City. Using case study examples, the report outlines limitations to the city’s current TDR policies and suggests a policy approach that could unlock millions of square feet of unused air rights to help produce more affordable housing.

Zoning for Affordability: Using the Case of New York to Explore Whether Zoning can be Used to Achieve Income-Diverse Neighborhoods
This article considers the legal limitations on a locality’s ability to regulate land use, in order to evaluate whether mandatory inclusionary zoning can withstand legal challenge. It uses New York City’s recently adopted, ambitious, mandatory inclusionary zoning policy as a case study, and considers how the city might justify the policy in the face of both constitutional and state law challenges. The article concludes that New York City’s policy is likely to survive, but there are open legal questions that make it hard to predict with certainty how the policy will ultimately fare. Inclusionary zoning policies in other jurisdictions are likely to face similar challenges, and the experience of New York City will hold important lessons for other high-cost cities interested in using land use r egulation to foster economically diverse neighborhoods.
