Buying Sky: The Market for Transferable Development Rights in New York City
The Furman Center for Real Estate & Urban Policy
New York City’s zoning code (known as the “Zoning Resolution”) regulates land use in part by limiting the square footage of the building that landowners can develop on their property. Some buildings are built below the applicable limit—because they are constrained by other regulations such as historic preservation rules, they were built subject to earlier, more-restrictive zoning rules, or the owner chose to develop the property less intensely than the zoning allows because of market conditions or other considerations applicable when the building was built. The Zoning Resolution provides limited opportunities for an owner of land that is less than fully developed to transfer her unused development rights to other properties. This enables the recipients of those development rights (known at that point as “transferrable development rights,” “TDRs,” or “air rights”) to develop larger buildings than the Zoning Resolution otherwise permits, while the seller loses the right to ever use those rights on her own property.

Curb Parking Pricing for Local Residents: An Exploration in New York City Based on Willingness to Pay
Guo, Zhan and S Mcdonnell
This paper investigates the feasibility of charging residents for on-street parking in dense urban neighborhoods as a way to clear parking supply and demand. We elicited residents’ willingness to pay (WTP) for a hypothetical parking permit program in New York City using a payment card approach, and estimate the key determinants through a Double Hurdle model. A little more than half of respondents (52.5%) are willing to pay for an average $408 per year, even though the revenue is not specified to be return back to the neighborhoods. Pricing becomes more acceptable in neighborhoods where the major parking problem is shortage and crowding caused mainly by local residents instead of parking intrusion by non-residents. The WTP value varies by resident car ownership and home parking types. The results suggest that curb parking pricing for local residents might be both economically and politically feasible in certain dense urban neighborhoods.
Street standards as parking policy: rethinking the provision of residential street parking in American suburbs
Journal of Planning Education and Research
Guo, Zhan and L Schloeter
This paper examines the parking mandate in residential street standards in the U.S. Based on literature review and a national survey of 97 principal cities in the top 52 metro areas, it reveals two unjustified assumptions behind the mandate: traffic lanes must maintain the continuous alignment even with limited, slow traffic and parking demand must be satisfied with dedicated parking lanes in absence of price. The mandate is likely to force market to over-supply parking and under-supply housing. The paper calls for the removal of the parking mandate from street standards, and the deregulation of the residential street parking market.
Residential Street Parking and Car Ownership
Journal of the American Planning Association 79.1 (2013): 32-48.
Problem, research strategy, and findings: Local governments’ minimum street-width standards may force developers to oversupply, and residents to pay excessively for, on-street parking in residential neighborhoods. Such oversupply is often presumed to both encourage car ownership and reduce housing affordability, although little useful evidence exists either way. This article examines the impact of street-parking supply on the car ownership of households with off-street parking in the New York City area.
The off- and on-street parking supply for each household was measured through Google Street View and Bing Maps. The impact of on-street parking on car ownership levels was then estimated in an innovative multivariate model. The unique set-up of the case study ensures 1) the weak endogeneity between parking supply and car ownership and 2) the low correlation between off-street and on-street parking supply, two major methodological challenges of the study. Results show that free residential street parking increases private car ownership by nearly 9%; that is, the availability of free street parking explains 1 out of 11 cars owned by households with off-street parking.
Takeaway for practice: These results offer support for community street standards that make on-street parking supply optional. They also suggest the merits of leaving the decisions of whether, and how many, on-street parking spaces to provide in new residential developments to private markets rather than regulations.

With population aging and increasing urbanization, it is important to examine the quality of life of older people living in cities, in particular world cities. However, few comparative studies of world cities examine their health, long-term care systems, or the characteristics of their older populations. To assess how well world cities are addressing the challenges associated with aging populations, it is helpful to review comparable data on the economic and health status of older persons, as well as the availability and use of health, social, and long-term care services. By extending the work of the “CADENZA: A Jockey Club Initiative for Seniors” Project and the World Cities Project, this chapter compares three world cities—Hong Kong, New York City, and London. The three world cities are similar in the size and proportion of their older populations, but the characteristics of older people and the health and long-term care systems available to them differ in signiﬁcant ways. These comparisons reveal how Hong Kong, New York City, and London are responding to a rapidly aging population. They should be valuable to other cities that face the challenges of population aging.
IESP Brief: Public Funding for After-School Programs 1998-2008
Weinstein, M., Calabrese, T.
The authors of this policy brief document that in the decade since the Open Society Institute awarded a challenge grant to TASC to encourage the creation of sustainable public funding streams for after-school programs, every level of government has dramatically increased public funding for comprehensive after-school programs in New York City.
The authors note that the City of New York has contributed an increasingly larger share of public support since the city launched its Out-of-School Time Initiative to provide kids with academic, cultural and recreational activities after school and during summers. The authors estimate that eight times more kids in kindergarten through high school attend after-school programs today than in 1998. "Over the past ten years in New York City," they conclude, "public support for after-school programs has become one of the foundations of service for children and youth."
The Greatest Grid: The Master Plan of Manhattan, 1811-2011
Laying out Manhattan's street grid and providing a rationale for the growth of New York was the city's first great civic enterprise, not to mention a brazenly ambitious project and major milestone in the history of city planning. The grid created the physical conditions for business and society to flourish and embodied the drive and discipline for which the city would come to be known. Published to coincide with an exhibition at the Museum of the City of New York celebrating the bicentennial of the Commissioners' 1811 Plan of Manhattan, this volume does more than memorialize such a visionary effort, it serves as an enduring reference full of rare images and information.
The Greatest Grid shares the history of the Commissioners' plan, incorporating archival photos and illustrations, primary documents and testimony, and magnificent maps with essential analysis. The text, written by leading historians of New York City, follows the grid's initial design, implementation, and evolution, and then speaks to its enduring influence. A foldout map, accompanied by explanatory notes, reproduces the Commissioners' original plan, and additional maps and prints chart the city's pre-1811 irregular growth patterns and local precedent for the grid's design. Constituting the first sustained examination of this subject, this text describes the social, political, and intellectual figures who were instrumental in remaking early New York, not in the image of old Europe but as a reflection of other American cities and a distinct New World sensibility. The grid reaffirmed old hierarchies while creating new opportunities for power and advancement, giving rise to the multicultural, highly networked landscape New Yorkers thrive in today.
Assessing the cost of transfer inconvenience in public transport systems: A case study of the London Underground
Transportation Research Part A: Policy and Practice, Vol. 45, 2, 91-104
Guo, Zhan and Nigel H.M. Wilson
Few studies have adequately assessed the cost of transfers in public transport systems, or provided useful guidance on transfer improvements, such as where to invest (which facility), how to invest (which aspect), and how much to invest (quantitative justification of the investment). This paper proposes a new method based on path choice,3 taking into account both the operator's service supply and the customers' subjective perceptions to assess transfer cost and to identify ways to reduce it. This method evaluates different transfer components (e.g., transfer walking, waiting, and penalty) with distinct policy solutions and differentiates between transfer stations and movements.
The method is applied to one of the largest and most complex public transport systems in the world, the London Underground (LUL), with a focus on 17 major transfer stations and 303 transfer movements. This study confirms that transfers pose a significant cost to LUL, and that cost is distributed unevenly across stations and across platforms at a station.
Transfer stations are perceived very differently by passengers in terms of their overall cost and composition. The case study suggests that a better understanding of transfer behavior and improvements to the transfer experience could significantly benefit public transport systems.
Mind the Map! The Impact of Transit Maps on Path Choice in Public Transit
Transportation Research Part A: Policy and Practice, Vol. 45, 7, 625–639
This paper investigates the impact of schematic transit maps on passengers' travel decisions. It does two things: First, it proposes an analysis framework that defines four types of information delivered from a transit map: distortion, restoration, codification, and cognition. It then considers the potential impact of this information on three types of travel decisions: location, mode, and path choices.1 Second, it conducts an empirical analysis to explore the impact of the famous London tube map on passengers' path choice in the London Underground (LUL). Using data collected by LUL from 1998 to 2005, the paper develops a path choice model and compares the influence between the distorted tube map (map distance) and reality (travel time) on passengers' path choice behavior. Results show that the elasticity of the map distance is twice that of the travel time, which suggests that passengers often trust the tube map more than their own travel experience on deciding the ‘‘best'' travel path. This is true even for the most experienced passengers using the system. The codification of transfer connections on the tube map, either as a simple dot or as an extended link, could affect passengers' transfer decisions. The implications to transit operation and planning, such as trip assignments, overcrowding mitigation, and the deployment of Advanced Transit Information System (ATIS), are also discussed.
Fine particulate matter pollution linked to respiratory illness in infants and increased hospital costs
Health Aff (Millwood). 2011 May;30(5):871-8.
Sheffield P, Roy A, Wong K, Trasande L.
There has been little research to date on the linkages between air pollution and infectious respiratory illness in children, and the resulting health care costs. In this study we used data on air pollutants and national hospitalizations to study the relationship between fine particulate air pollution and health care charges and costs for the treatment of bronchiolitis, an acute viral infection of the lungs. We found that as the average exposure to fine particulate matter over the lifetime of an infant increased, so did costs for the child's health care. If the United States were to reduce levels of fine particulate matter to 7 percent below the current annual standard, the nation could save $15 million annually in reduced health care costs from hospitalizations of children with bronchiolitis living in urban areas. These findings reinforce the need for ongoing efforts to reduce levels of air pollutants. They should trigger additional investigation to determine if the current standards for fine-particulate matter are sufficiently protective of children's health.

While current rates of sea level rise and associated coastal flooding in the New York City region appear to be manageable by stakeholders responsible for communications, energy, transportation, and water infrastructure, projections for sea level rise and associated flooding in the future, especially those associated with rapid icemelt of the Greenland and West Antarctic Icesheets, may be outside the range of current capacity because extreme events might cause flooding beyond today's planning and preparedness regimes. This paper describes the comprehensive process, approach, and tools for adaptation developed by the New York City Panel on Climate Change (NPCC) in conjunction with the region's stakeholders who manage its critical infrastructure, much of which lies near the coast. It presents the adaptation framework and the sea-level rise and storm projections related to coastal risks developed through the stakeholder process. Climate change adaptation planning in New York City is characterized by a multi-jurisdictional stakeholder-scientist process, state-of-the-art scientific projections and mapping, and development of adaptation strategies based on a risk-management approach.
Climate Change Mitigation and Adaptation in North American Cities
Available on line January 7, 2011, Current Opinion in Environmental Sustainability, Vol. 3, 2011, pp. 181-187 doi:10.1016/j.cosust.2010.12.004

Climate change mitigation and adaptation action plans are developing at a rapid pace, being driven by both local initiatives and emerging alliances and support organizations that cut across multiple jurisdictions. These plans include a broad range of approaches, many of which are evolving into best or leading practices and which will be increasingly used as a model for the plans of other locales. This paper draws attention to several best practices in both mitigation and adaptation for North American cities, and also highlights many of the supporting alliances and groups that disseminate key practices and drive potential synergies. Additionally, it is noted that despite the increasing rate of plan development, a continuing need exists for increased attention to adaptation at the local level.
Resource Allocation, Emergency Response Capability and Infrastructure Concentration Around Vulnerable Sites
First published on: 14 April 2011, forthcoming 2011, Journal of Risk Research, 18pp. doi:10.1080/13669877.2010.547257

Public and private decision-makers continue to seek risk-based approaches to allocate funds to help communities respond to disasters, accidents, and terrorist attacks involving critical infrastructure facilities. The requirements for emergency response capability depend both upon risks within a region's jurisdiction and mutual aid agreements that have been made with other regions. In general, regions in close proximity to infrastructure would benefit more from resources to improve preparedness because there is a greater potential for an event requiring emergency response to occur if there are more facilities at which such events could occur. Thus, a potentially important input into decisions about allocating funds for security is the proximity of a community to high concentrations of infrastructure systems that potentially could be at risk to an industrial accident, natural disaster, or terrorist attack. In this paper, we describe a methodology for measuring a region's exposure to infrastructure-related risks that captures both a community's concentration of facilities or sites considered to be vulnerable and of the proximity of these facilities to surrounding infrastructure systems. These measures are based on smoothing-based nonparametric probability density estimators, which are then used to estimate the probability of the entire infrastructure occurring within any specified distance of facilities in a county. The set of facilities used in the paper to illustrate the use of this methodology consists of facilities identified as vulnerable through the California Buffer Zone Protection Program. For infrastructure in surrounding areas we use dams judged to be high hazards, and BART tracks. The results show that the methodology provides information about patterns of critical infrastructure in regions that is relevant for decisions about how to allocate terrorism security and emergency preparedness resources.
To Leave An Area After Disaster: How Evacuees from the WTC Buildings Left the WTC Area Following the Attacks.
Risk Analysis, Vol. 31, Issue 5, 2011, published on line December 8, 2010. doi:10.1111/j.1539-6924.2010.01537

How people leave a devastated area after a disaster is critical to understanding their ability to cope with risks they face while evacuating. Knowledge of their needs for communications about these risks is particularly crucial in planning for emergency responses. A convenience sample of 1,444 persons who survived the World Trade Center (WTC) attacks on September 11, 2001 were surveyed to ascertain their initial and ultimate destinations once they had left the buildings, how they arrived there, the role of types of obstacles they encountered, and the need for information and the seeking of other people as potential factors in influencing the process of leaving immediately. This survey was part of a larger, original survey. Results showed differences in how people traveled by mode to initial and ultimate destinations, how immediately they left the area, and factors associated with when they left. How they traveled and when they left were associated with where people lived, their tendency in times of stress to seek out other people including who they knew in the immediate area (e.g., co-workers or friends), the physical conditions surrounding them, and the importance to some of waiting for more information. Many people indicated they did not leave immediately because they had no information about where to go or what services would be available to them. Perceptions and communications about risks they were facing were reflected in the choices they considered in how and when to leave the area. These findings have numerous ramifications for understanding and guiding personal behavior in catastrophic situations.
New York City Quarterly Housing Update 2010: 3rd Quarter
Furman Center for Real Estate and Urban Policy.
After analyzing six key indicators of housing market performance for the third quarter of 2010, NYU's Furman Center finds that New York City home prices are stabilizing, but still remain 22% below peak. The report also finds that a decrease in third-quarter foreclosure filings compared to last year may point to a slowdown in the foreclosure crisis. The Quarterly Housing Update incorporates sales data, development indicators and foreclosures, and presents a repeat sales index for each borough to capture price appreciation while controlling for housing quality.
The Rise and Fall of a Micro-Learning Region: Mexican Immigrants and Construction in Center-South Philadelphia
2010. Environment and Planning A, Volume 42, Number 7
Iskander, Natasha, Nichola Lowe, and Christine Riordan
This paper documents the rise and fall of a micro-learning region in Philadelphia. The central actors in this region are undocumented Mexican immigrants who until recently were able to draw on the intensity of their workplace interactions and their heterodox knowledge to produce new and innovative building techniques in the city's residential construction. The new knowledge they developed was primarily tacit. More significantly, the learning practices through which immigrant workers developed skill and innovated new techniques were also heavily tacit. Because these practices were never made formal and were never made explicit, they remained invisible and difficult to defend. With the housing market collapse and subsequent decline in housing renovation in south-center region of Philadelphia, this tacit knowledge and the practices that gave it shape and significance, are no longer easily accessible. We draw on this case to demonstrate the importance of access to the political and economic resources to turn learning practices into visible structured institutions that protect knowledge and skill. Whether or not the practices that support knowledge development are themselves made explicit can determine whether the knowledge they produce becomes an innovation that is recognized and adopted or whether it remains confined to a set of ephemeral practices that exist only so long as they are being enacted.
