As a part of the educational activities of the Lincoln Institute’s Latin America Program, a course on “Large Urban Projects,” held in Cambridge last June, focused on the most important and challenging aspects of this land planning issue. Academics, public officials and representatives from private enterprises in 17 cities participated in the presentations and discussions. This article presents a synthesis of the principal points, questions and challenges raised in carrying out these complex projects.
Large urban redevelopment projects have become an important issue in many Latin American countries recently, due in part to changes motivated by the processes of globalization, deregulation and the introduction of new approaches in urban planning. These projects include varied types of interventions, but they are characterized primarily by their large size and scale, which challenge traditional instruments of urban management and financing.
Urban projects on a grand scale are not considered a novelty in Latin America. The diverse elements of existing developments include the revitalization of historic centers; conversion of abandoned industrial facilities, military areas, airports or train stations; large slum rehabilitation projects; and construction of innovative public transportation models. However, at least four important features characterize this new type of intervention:
The last feature is reinforced by the influence of different planning strategies and the impacts of large urban projects in various cities around the world (Powell 2000). One project that has influenced many city planners and officials in Latin America was the transformation of Barcelona in preparation for the Olympic Games in 1992 (Borja 1995). Several projects in Latin America have been inspired by, if not directly emulated, this approach (Carmona and Burgess 2001), but it also has faced serious criticism (Arantes, Vainer and Maricato 2000). It has been seen as a convenient process through which a group of decision makers or private interest stakeholders manage to bypass official planning and policy channels that are seen to be too dependent on the public (democratic) debate. As a result most such projects tend to be either elitist, because they displace low-income neighborhoods with gentrified and segregated upper-class land uses, or are socially exclusionary, because they develop single-class projects, either low-income settlements or high-income enclaves, in peripheral locations.
Large-scale projects raise new questions, make inherent contradictions more transparent, and challenge those responsible for urban land analysis and policy formulation. Of special importance are the new forms of management, regulation, financing and taxation that are required for or result from the execution of these projects, and in general the consequences for the functioning of land markets.
Size, Scale and Timeframe
The first issue that emerges from a discussion of large-scale projects has to do with the ambiguity of the term and the necessity of defining its validity. Size is a quantitative dimension, but scale suggests complex interrelations involving socioeconomic and political impacts. The wide variety of feelings evoked by large projects shows the limitations in being able to restore a vision of the urban whole and at the same time its global character (Ingallina 2001). This issue has just begun to be discussed in Latin America, and it is framed in the transition to a new approach in urban planning, which is related to the possibility and even the necessity of constructing a typology and indicators for its analysis. Issues such as the emblematic character of these projects, their role in stimulating other urban processes, the involvement of many actors, and the significance of the impacts on the life and development of the city are all part of the discussions. Nevertheless, it is the scale, understood as being more than just simple physical dimensions, that is the central core of this theme.
Since the scale of these projects is associated with complex urban processes that combine continuity and changes over the medium and long terms, the timeframe of their execution must be conceived accordingly. Many of the failures in the implementation of such projects have to do with the lack of a managing authority that would be free or protected from the political volatility of local administrations over time.
The cases of Puerto Madero in Buenos Aires and Fenix in Montevideo, the first completed and the second in process, offer examples of the difficulties in managing the scale and timing of development in the context of economic situations and policies that can change drastically. Twelve years after its construction, Puerto Madero has not yet stimulated other large-scale projects, such as the renovation of nearby Avenida de Mayo, nor appreciable transformations in urban norms.
The scale and timeframe are particularly important for the project in Montevideo, raising doubts about the feasibility of executing a project of this scale in relation to the character of the city, its economy, and other priorities and policies of the country. Its goal was to generate a “work of urban impact,” in this case promotion of public, private and mixed investments in a neighborhood that lost 18.4 percent of its population between 1985 and 1996, and focusing on an emblematic building, the old General Artigas train station. Most of this work has been executed, with a loan of $28 million from the Inter-American Development Bank, however the percentage of public and private investments are minimal and the Fenix project is having to compete with another large-scale corporate-commercial development located east of the city that is already attracting important firms and enterprises.
Land Policy Issues
The issue of scale relates intrinsically to the role of urban land, which makes one ask if land (including its value, uses, ownership and other factors) should be considered a key variable in the design and management of large-scale urban operations, since the feasibility and success of these projects are often associated with the internalization of formidable externalities often reflected in the cost and management of the land.
Projects to restore historic centers offer important lessons to be considered here. We can compare the cases of Old Havana, where land ownership is completely in the hands of the state, which has permitted certain activities to expand, and Lima, where land ownership is divided among many private owners and public sector agencies, adding to the difficulties in completing an ongoing restoration project. Even though Old Havana has received important financial cooperation from Europe and Lima has a $37 million loan from the Inter-American Development Bank, the main challenge is to promote private investment while also maintaining programs of social and economic assistance for the local residents. Both cities have created special units for the management of these projects, which constitutes an interesting commentary on institutional modernization.
The Role of the State
The scale, the time dimension and the role of land in large urban projects lead us to consider the role of the state and public investment. While urban operations on a large scale are not new in Latin American cities, their present conditions have been affected radically by economic changes, political crises and substantial modifications in the role of the state in general. These conditions make the execution of urban projects, as part of the process of long-term urban development, a source of contradictions with the generally short tenure of municipal governments and the limits of their territorial claims. We must also consider the differences in regulatory competencies between central governments and local municipalities, and the differences between public entities and private institutions or local community organizations, which often reflect conflicting interests due the decentralization and privatization processes being promoted simultaneously in many countries.
Two large projects related to transportation infrastructure are examples of local situations that led to very different results. One was the transformation of the old abandoned Cerrillos airport in Santiago, Chile, and the other was a project for a new airport for Mexico City in Texcoco, an area known as ejido land occupied by peasants and their descendants. In the first case, the active participation of interested groups is expanding the recuperation process of a zone of the city that does not have quality urban facilities. A total investment of $36 million from the public sector and $975 million from the private sector is supporting the construction of malls, facilities for education, health and recreation, and housing for the neighborhood. In Mexico serious conflicts between state interests and community rights to the land had caused social unrest and even the kidnapping of public officials. As a result, the federal government has recently withdrawn from the Texcoco project, assuming huge political and economic costs for this decision.
Segregation and Exclusion
Many planners and practitioners have doubts about the feasibility of large projects in poor countries and cities because of the distortions that their execution could cause on future development, in particular the reinforcing tendencies of segregation and social exclusiveness. The diminishing capacity of the state to look for new alternatives for financing socially beneficial projects through private capital, principally from international sources, adds to the doubts about their success. Many large-scale projects are seen as the only alternative or the unavoidable cost that the city or society has to pay to generate an attractive environment in a context of growing competition among cities for a limited number of external investors.
A key matter with respect to the use of public space generated by these projects is to avoid segregation of space and people. Special attention must be given to protect the inhabitants of the zones where the large urban projects are developed from the negative consequences of gentrification. This is without a doubt one of the most difficult aspects of large urban projects. Table 1 shows the most important aspects and the principal challenges that arise from an analysis of the large urban projects. Effectively, the integration of projects of this scope calls for a vision of the city that avoids the creation of islands of modernity isolated in the middle of poor areas, which would contribute to the process called the dualism of the city, or the generation of new exclusive urban centers.
Table 1: Aspects and Challenges of Large Urban Projects
| Aspects | Challenges |
|---|---|
| Urban grid | Integrate the project into the existing city fabric |
| Planning process | Design the project to be compatible with the established approach to city planning strategies |
| Urbanistic norms and regulations | Avoid the creation of norms giving privileges of exclusiveness to the project |
| Stakeholders | Incorporate all participants involved directly, in particular the not so easily identifiable groups indirectly affected by these projects |
| Financing | Establish innovative public and private partnerships |
| Social, economic and urban impacts | Develop effective ways to measure and assess various types of impacts and ways to mitigate the negative effects |
Two cases in different political-economic contexts help us reflect about this matter. One is the El Recreo project, planned by Metrovivienda, in Bogotá. Although presenting innovative proposals about the use and management of the land in a large project for popular housing, the project has not been able to guarantee the integration of social groups with different income levels. In the Corredor Sur area of Panama City large zones are being planned for the construction of residences, but the result again serves primarily medium- and high-income sectors. Thus in both a decentralized and a centralized country the general norms that provoke residential segregation cannot seem to prevent negative consequences for the poorest sectors of society.
In view of all this, large urban projects should not be seen as an alternative approach to obsolete plans or rigid norms like zoning. They could instead be presented as a kind of intermediate-scale planning, as an integrated approach that addresses the needs of the whole city and avoids physical and social separations and the creation of norms that permit exclusive privileges. Only in this way can large-scale projects take their place as new instruments for urban planning. The positive effects of specific elements such as the quality of architecture and urban design are valuable in these projects if they operate as a benchmark and are distributed with equity throughout the city.
Public Benefits
Large-scale projects are public projects by the nature of their importance and impact, but that does not mean they are the total property of the state. Nevertheless, the complexity of the participant networks involved directly or indirectly, the variety of interests and the innumerable contradictions inherent in large projects require a leading management role by the public sector. The territorial scale of these operations especially depends on the support of the municipal governments, which in Latin America often lack the technical resources to manage such projects. Local support can guarantee a reduction of negative externalities and the involvement of weaker participants, generally local actors, through a more just distribution of the benefits, where the regulation of the use and taxation of the land is a key issue. Such is the intention of the Municipality of Santo Andre in Sao Paulo in the design of the extraordinarily complex Tamanduatehy project. It involves the reuse of an enormous tract of land previously occupied by railroad facilities and neighboring industrial plants that fled this once vigorous industrial belt of Sao Paulo to relocate in the hinterland. The project involves establishing a viable locus of new activities, mostly services and high-tech industries, capable of replacing the economic base of that region.
Beyond creating and marketing the image of the project, it is important to achieve social legitimacy through a combination of public and private partners engaged in joint ventures, the sale or renting of urban land, compensation for direct private investment, regulation, or even public recovery (or recapture) of costs and/or of unearned land value increments. Active public management is also necessary, since the development of the city implies common properties and benefits, not only economic interests. Analysis of economic and financial costs, and opportunity costs, are also important to avoid the failure of these projects.
Conclusions
The basic components in the pre-operational stage of executing large urban projects can be summarized as follows:
An adequate analysis of the trade-offs (economic, political, social, environmental, and others) is indispensable, even if it is clear that the complex problems of the contemporary city cannot be solved with large interventions alone. It is important to reiterate that more importance must be given to the institutionalization and legitimacy of the final plans and agreements than simply the application of legal norms.
The presentations and discussions at the course on “Large Urban Projects” show that the matter of urban land strongly underlies all the aspects and challenges described above. Land in this type of project presents a huge complexity and offers a great opportunity; the challenge is how to navigate between the interests and conflicts when there are many owners and stakeholders of the land. It is necessary to combat the temptation to believe that modern urban planning is the sum of large projects. Nevertheless, these projects can contribute to building a shared image of the city between the inhabitants and the users. This topic clearly has facets that have not been completely explored yet and that need continued collaborative analysis and by academics, policy makers and citizens.

Gerrit-Jan Knaap is an economist, professor of urban studies and planning, and executive director of the National Center for Smart Growth Research and Education at the University of Maryland, in College Park. His research interests include the economics and politics of land use planning, the efficacy of economic development instruments, and the impacts of environmental policy. His research in Oregon, Maryland and elsewhere has made him a recognized expert on land use policy and planning. He is the coauthor or editor of several books, including two published by the Lincoln Institute: The Regulated Landscape: Lessons on State Land Use Planning from Oregon (1992); and Land Market Monitoring for Smart Urban Growth (2001).
Land Lines: As director of the National Center for Smart Growth Research and Education, what land policy issues are you addressing now?
Gerrit-Jan Knaap: This Center has been in existence for only three years, but this year it is finally getting established and recognized. In the past year we have been able to pull together a core group of national and international researchers who are now working in three key areas: land use and environment; transportation and public health; and international urban development. The Center is also recruiting a faculty researcher to concentrate on housing and community development.
LL: What are the Center’s most difficult challenges?
GK: Ironically, the Center’s name is a problem. While the phrase “smart growth” is helpful shorthand for describing an approach to land use planning and management, some people identify the term with liberal causes or with former Maryland Governor Parris Glendening or the Clinton-Gore administration. As a result, the phrase has been politicized in a way that causes confusion and polarized reactions. The Center does not support or oppose smart growth; it is just an adjective modifying what we do: research and education.
We have found, however, that it is more difficult to obtain funding for objective research on growth management and planning issues than it is to obtain funding for activities that advocate either for or against smart growth. The Lincoln Institute’s willingness to fund independent, objective, high-quality research in this field fills an important niche.
LL: What are some of the Center’s most significant projects?
GK: We are doing a lot of work to develop quantitative measures of urban form. We are not alone in this enterprise, but we think we’re still a step ahead of other research centers in applying such measures to policy issues. Reid Ewing, a nationally recognized expert on growth management, community development and traffic management, recently joined the staff. He and others, for example, have developed a sprawl index that they use to explore the relationship between sprawl and obesity, which is part of our public health focus.
Yan Song, a former post-doctoral fellow in the Center and now an assistant professor at the University of North Carolina, developed quantitative measures of urban form and used them to explore whether Portland, Oregon, was winning the battle against urban sprawl. She also used them to determine whether characteristics like street network connectivity, residential density, land use mix and pedestrian accessibility to commercial uses were capitalized into property values. Most recently, she has used the measures to classify neighborhoods into clusters with similar design characteristics as a means of classifying the types of neighborhood that are currently being built.
Another major focus of our work is land policy and growth management in the People’s Republic of China. As a result of recent economic growth and reforms, China’s 1.3 billion people are urbanizing at an astonishing rate, creating an unprecedented growth management challenge. The Chinese are struggling to find a way to accommodate urban growth and, at the same time, preserve their ability to feed their people. Though we certainly do not have all the answers, Chinese scholars and public officials are interested in learning from our experiences in confronting and balancing these challenges. Chengri Ding, another member of the Center’s faculty, is leading this work with support from the Lincoln Institute. He and Yan Song are editing a book on the evolution of land and housing markets in China that will be published by the Institute later this year.
Our third major focus area is land market monitoring, which grew out of my work in Oregon. Land market monitoring is based on the idea that urban growth management is partly an inventory problem: too much land can lead to urban sprawl, but too little land may create land and housing price inflation. Maintaining balance requires accurate and timely information about land supplies, development capacity, land and housing prices, natural resource constraints and urban development demands. We have conducted several workshops around the country on land market monitoring, and now we are working with the U.S. Department of Housing and Urban Development (HUD) and the Lincoln Institute to establish a national demonstration project.
LL: How did you develop this concept of land market monitoring?
GK: It started with my dissertation work on the price effects of the urban growth boundary (UGB) in Portland, Oregon. Later, at the University of Illinois, Lew Hopkins and I worked on a project we called, “Does Planning Matter?” We sought to develop planning support systems that not only helped to improve land use decision making, but also helped identify the effects of land use plans and regulations on urban development patterns (Ding, Hopkins and Knaap 1997). Building on this work, I organized a conference at the Lincoln Institute in Cambridge in 2000 and invited a group of leading scholars to present papers on this issue. These papers were published by the Institute in the book Land Market Monitoring for Smart Urban Growth, which was recently translated into Chinese. The idea of measuring development capacity and the need for housing is actually as old as planning itself, but recent advances in GIS technology and digital data bases makes it possible to monitor development capacity on a nearly continuous basis.
LL: How are these ideas being used by planners in the U.S.?
GK: Well, to a large extent, they are not. Typical planning practice in the U.S. still involves the formulation of a comprehensive plan—usually for a 10- to 20-year period—then implementing the plan, and then, after 5 to 10 years, formulating a new plan. With a land market monitoring system it is possible to shorten this cycle considerably. In the extreme, it is conceptually possible to monitor development capacity and urban development trends on a continuous basis and make adjustments as needed. Most planners, however, are not trained to think about growth management issues in this way.
LL: What are the obstacles to using land market monitoring in different locales?
GK: The major obstacles are: (1) the lack of quality data; (2) the lack of intergovernmental cooperation; and (3) the lack of political will to place this issue high on the agenda. The primary problem is not money. To do land market monitoring correctly requires a certain level of resource commitment, but since virtually every local government is developing GIS data and has the necessary technical capacity, it is not difficult to develop an operational monitoring system.
There are some positive examples, however. Monitoring of some kind has been required in Oregon for many years; for this reason, Metro, the regional government for the Portland metropolitan area, has developed an extensive monitoring system (Knaap, Bolen and Seltzer 2003). In its Growing Smart Guidebook, the American Planning Association recommends that any local government that adopts an urban growth boundary also should develop a land monitoring system. Most recently, Maryland Governor Robert L. Ehrlich Jr. signed an executive order that will initiate a pilot program of land market monitoring in five cities and five counties, and I will serve on the task force that oversees that demonstration project.
LL: What are your plans for the future?
GK: We have two demonstration projects under way. In the first, we are working with the Maryland Department of Planning to develop a series of indicators to assess the progress of the state’s Smart Growth program. These indicators will measure development capacity as well as housing starts and prices, acres of land protected from development, vehicle miles traveled, transit ridership and other trends that will help state officials and the public judge the effectiveness of smart growth policies.
Second, we have just completed phase one of a national demonstration project that was jointly funded by HUD, the Federal Highway Administration and the Lincoln Institute. We identified a generic protocol for conducting a development capacity analysis, applied this protocol to 15 counties in Maryland, and held workshops on monitoring in several metropolitan areas around the country. With Zorica Nedovic-Budic, we also conducted an assessment of the capacity of regional governments to use GIS for land use and transportation planning (see http://www.urban.uiuc.edu/faculty/budic/W-metroGIS.htm). We hope to begin the second phase of that project early in 2004 in five selected sites around the country. Phase two will focus first on residential development capacity, then on employment development capacity, then on how to tie together land use forecasting with transportation planning.
We’re also exploring the possibility of setting up a land market monitoring demonstration project in China, in conjunction with the Lincoln Institute’s new China program.
LL: So where does smart growth go next?
GK: What will happen to the expression “smart growth” is difficult to say. Governor Ehrlich has started calling his version of Maryland’s land use program “Priority Places,” but all of the newspapers still refer to his effort as smart growth. So, it remains to be seen whether the phrase becomes part of the national lexicon or fades like the Macarena. There is no doubt, however, that the issues associated with the term “smart growth” will not go away, in Maryland, around the country, or even overseas. We think this Center is now well-positioned to become an important and objective source of information and education on these issues well into the future.
