Smart growth is an urban urban planning and transportation theory that concentrates growth in compact walkable urban centers to avoid urban sprawl. It also advocates compact, transit-oriented, walkable, bicycle-friendly land use, including neighborhood schools, complete streets, and mixed-use development with a range of housing choices. The term "smart growth" is particularly used in North America. In Europe and particularly the UK, the terms "compact city", "urban densification"Varma, G. An Analysis on the Concept of Urban Densification and its Implications on Transportation. Linkedin, 2016. link. or "urban intensification" have often been used to describe similar concepts, which have influenced government planning policies in the UK, the Netherlands and several other European countries.
Smart growth values long-range, regional considerations of sustainability over a short-term focus. Its sustainable development goals are to achieve a unique sense of community and Placemaking; expand the range of transportation, employment, and housing choices; equitably distribute the costs and benefits of development; preserve and enhance natural and cultural resources; and promote public health.
Smart growth "principles" describe the elements of community that are envisioned and smart growth "regulations" describe the various approaches to implementation, that is, how federal, state, and municipal governments choose to fulfill smart growth principles. Some of these regulatory approaches such as urban growth boundaries predate the use of the term "smart growth". One of the earliest efforts to establish smart growth forward as an explicit regulatory framework were put forth by the American Planning Association (APA). In 1997, the APA introduced a project called Growing Smart and published the "Growing Smart Legislative Guidebook: Model Statutes for Planning and the Management of Change." The U.S. Environmental Protection Agency (EPA) defines smart growth as “a range of development and conservation strategies that help protect our health and natural environment and make our communities more attractive, economically stronger, and more socially diverse." Smart growth agenda is comprehensive and ambitious, however, its implementation is problematic as control of outward movement means limiting availability of single-family homes and reliance on the automobile, the mainstay of the traditional American lifestyle.
Smart growth is related to, or may be used in combination with, the following concepts:
The smart growth approach to development is multifaceted and can encompass a variety of techniques. For example, in the state of Massachusetts smart growth is enacted by a combination of techniques including increasing housing density along transit nodes, conserving farm land, and mixing residential and commercial use areas. Perhaps the most descriptive term to characterize this concept is Traditional Neighborhood Development, which recognizes that smart growth and related concepts are not necessarily new, but are a response to car culture and sprawl. Many favor the term New Urbanism, which invokes a new, but traditional way of looking at urban planning.
There are a range of best practices associated with smart growth. These include supporting existing communities, redeveloping underutilized sites, enhancing economic competitiveness, providing more transportation choices, developing livability measures and tools, promoting equitable and affordable housing, providing a vision for sustainable growth, enhancing integrated planning and investment, aligning, coordinating, and leveraging government policies, redefining housing affordability and making the development process transparent.
Related, but somewhat different, are the overarching goals of smart growth, and they include: making the community more competitive for new businesses, providing alternative places to shop, work, and play, creating a better "Sense of Place," providing jobs for residents, increasing property values, improving quality of life, expanding the tax base, preserving open space, controlling growth, and improving safety.
The Congress for the New Urbanism, with architect Peter Calthorpe, promoted and popularized the idea of that relied on public transportation, bicycling, and walking instead of automobile use. Architect Andrés Duany promoted changing design codes to promote a sense of community, and to discourage driving. Colin Buchanan and Stephen Plowden helped to lead the debate in the United Kingdom.
The Local Government Commission which presents the annual New Partners for Smart Growth conference adopted the original Ahwahnee Principles in 1991 which articulates many of the major principles now generally accepted as part of the smart growth movement such as transit oriented development, a focus on walking distance, greenbelts and wildlife corridors, and infill and redevelopment. The document was co-authored by several of the founders of the New Urbanist movement. The Local Government Commission has been co-sponsoring smart growth-related conferences since 1997. The New Partners for Smart Growth Conference started under that name circa 2002.
Smart Growth America, an organization devoted to promoting smart growth in the United States, was founded in 2002. This organization leads an evolving coalition of national and regional organizations most of which predated its founding such as 1000 Friends of Oregon, founded in 1975, and the Congress for the New Urbanism, founded in 1993. The EPA launched its smart growth program in 1995.
New Jersey, for example, has implemented a plan that divides the state into five planning areas, some of which are designated for growth, while others are protected. The state is developing a series of incentives to coax local governments into changing zoning laws that will be compatible with the state plan. The New Jersey Board of Public Utilities recently proposed a revised rule that presents a tiered approach to utility financing. In areas not designated for growth, utilities and their ratepayers are forbidden to cover the costs of extending utility lines to new developments—and developers will be required to pay the full cost of public utility infrastructure. In designated growth areas that have local smart plans endorsed by the State Planning Commission, developers will be refunded the cost of extending utility lines to new developments at two times the rate of the revenue received by developers in smart growth areas that do not have approved plans.
In sustainable architecture the recent movements of New Urbanism and New Classical Architecture promote a sustainable approach towards construction, that appreciates and develops smart growth, architectural tradition and classical design. This in contrast to modernist and globally uniform architecture, as well as leaning against solitary and Urban sprawl. Issue Brief: Smart-Growth: Building Livable Communities . American Institute of Architects. Retrieved on 2014-03-23. Both trends started in the 1980s.
In communities practicing these smart growth policies, developers comply with local codes and requirements. Consequently, developer compliance builds communal trust because it demonstrates a genuine interest in the environmental quality of the community.
The smart growth network has recognized these U.S. communities for implementing smart growth principles:
The European Union has recognized these cities and regions for implementing "smart specialization" which originated from smart growth principles:
In May 2011, The European Union released a Regional Policy report for smart growth policy for 2020. The Regional Policy report stated smart specialization was the strategy to focus Europe's resources and administer smart growth principles.
In July 2011, The Atlantic magazine called the BeltLine, a series of housing, trail, and transit projects along a 22-mile (35-km) long disused rail corridor surrounding the core of Atlanta, the United States' "most ambitious smart growth project".
In Savannah, Georgia (US) the historic Oglethorpe Plan has been shown to contain most of the elements of smart growth in its network of wards, each of which has a central civic square. The plan has demonstrated its resilience to changing conditions, and the city is using the plan as a model for growth in newer areas.Wilson, Thomas D. The Oglethorpe Plan: Enlightenment Design in Savannah and Beyond. University of Virginia Press, 2012. chapters 4 and 5.
In Melbourne, Australia, almost all new outer-suburban developments are master planned, guided by the principles of smart growth.
Within cities studies from across many countries (mainly in the developed world) have shown that denser urban areas with greater mixture of land use and better public transport tend to have lower car use than less dense suburban and ex-urban residential areas. This usually holds true even after controlling for socio-economic factors such as differences in household composition and income.e.g. FRANK, L. and PIVOT, G., 1994. Impact of Mixed Use and Density on Three Modes of Travel. Transportation Research Record, 1446, pp. 44-52. This does not necessarily imply that suburban sprawl causes high car use, however. One confounding factor, which has been the subject of many studies, is residential self-selection: people who prefer to drive tend to move towards low density suburbs, whereas people who prefer to walk, cycle or use transit tend to move towards higher density urban areas, better served by public transport. Some studies have found that, when self-selection is controlled for, the built environment has no significant effect on travel behaviour.e.g. Bagley, M.N. and Mokhtarian, P.L. (2002) The impact of residential neighborhood type on travel behavior: A structural equations modeling approach. Annals of Regional Science36 (2), 279. More recent studies using more sophisticated methodologies have generally refuted these findings: density, land use and public transport accessibility can influence travel behaviour, although social and economic factors, particularly household income, usually exert a stronger influence.e.g.Handy, S., Cao, X. and Mokhtarian, P.L. (2005) Correlation or causality between the built environment and travel behavior? Evidence from Northern California. Transportation Research Part D: Transport and Environment10 (6), 427-444.
For example, Portland, Oregon a U.S. city which has pursued smart growth policies, substantially increased its population density between 1990 and 2000 when other US cities of a similar size were reducing in density. As predicted by the paradox, traffic volumes and congestion both increased more rapidly than in the other cities, despite a substantial increase in transit use.
These findings led them to propose the paradox of intensification, which states "Ceteris paribus, urban intensification which increases population density will reduce per capita car use, with benefits to the global environment, but will also increase concentrations of motor traffic, worsening the local environment in those locations where it occurs".
At the citywide level it may be possible, through a range of positive measures to counteract the increases in traffic and congestion which would otherwise result from increasing population densities: Freiburg im Breisgau in Germany is one example of a city which has been more successful in this respect.
This study also reviewed evidence on the local effects of building at higher densities. At the level of the neighbourhood or individual development positive measures (e.g. improvements to public transport) will usually be insufficient to counteract the traffic effect of increasing population density. This leaves policy-makers with four choices: intensify and accept the local consequences, sprawl and accept the wider consequences, a compromise with some element of both, or intensify accompanied by more radical measures such as parking restrictions, closing roads to traffic and .
In contrast, the city of Cambridge, Massachusetts reported that its Kendall Square neighborhood saw a 40% increase in commercial space attended by a traffic decrease of 14%."Car-free commuting push pays off in Kendall Square" Boston Globe, July 25, 2012. http://www.boston.com/news/local/massachusetts/articles/2012/07/25/in_kendall_square_car_traffic_falls_even_as_the_workforce_soars/
A report by CEOs for Cities, "Driven Apart," showed that while denser cities in the United States may have more congested commutes they are also shorter on average in both time and distance. This is in contrast to cities where commuters face less congestion but drive longer distances resulting in commutes that take as long or longer.Driven Apart, CEOs for Cities, 2010
Wendell Cox is a vocal opponent of smart growth policies. He argued before the United States Senate Committee on Environment and Public Works that, "smart growth strategies tend to intensify the very problems they are purported to solve."Wendell Cox, Testimony before the Senate Committee on Environment and Public Works, The Heritage Foundation, May 15, 2002 Cox and Joshua Utt analyzed smart growth and sprawl, and argued that:Wendell Cox and Joshua Utt, Heritage Foundation Backgrounder #1770, The Heritage Foundation, June 25, 2004
Our analysis indicates that the Current Urban Planning Assumptions are of virtually no value in predicting local government expenditures per capita. The lowest local government expenditures per capita are not in the higher density, slower growing, and older municipalities.On the contrary, the actual data indicate that the lowest expenditures per capita tend to be in medium- and lower-density municipalities (though not the lowest density); medium- and faster-growing municipalities; and newer municipalities. This is after 50 years of unprecedented urban decentralization, which seems to be more than enough time to have developed the purported urban sprawl-related higher local government expenditures. It seems unlikely that the higher expenditures that did not develop due to sprawl in the last 50 years will evolve in the next 20 - despite predictions to the contrary in The Costs of Sprawl 2000 research.
It seems much more likely that the differences in municipal expenditures per capita are the result of political, rather than economic factors, especially the influence of special interests.
The phrase "smart growth" implies that other growth and development theories are not "smart". There is debate about whether transit-proximate development constitutes smart growth when it is not transit-oriented. The National Motorists Association does not object to smart growth as a whole, but strongly objects to traffic calming, which is intended to reduce automobile accidents and fatalities,United States Department of Transportation - Federal Highway Administration, http://www.fhwa.dot.gov/environment/tcalm/part1.htm but may also reduce automobile usage and increase alternate forms of public transportation.San Mateo County Transport Authority: Alternative Congestion Relief Programs in San Mateo County, http://www.smcta.com/tatsm.asp
In 2002 the National Center for Public Policy Research, a self-described conservative think tank, published an economic study entitled "Smart Growth and Its Effects on Housing Markets: The New Segregation" which termed smart growth "restricted growth" and suggested that smart growth policies disfavor minorities and the poor by driving up housing prices.Randall J. Pozdena, Smart Growth and its Effects on Housing Markets: The New Segregation, QuantEcon, Inc., published by the National Center for Public Policy Research, November 2002
Some Libertarianism groups, such as the Cato Institute, criticize smart growth on the grounds that it leads to greatly increased land values, and people with average incomes can no longer afford to buy houses.Randal O'Toole, "The Folly of "Smart Growth"", Regulation, Fall 2001
A number of ecological economists claim that industrial civilization has already "overshot" the carrying capacity of the Earth, and "smart growth" is mostly an illusion. Instead, a steady state economy would be needed to bring human societies back into a necessary balance with the ability of the ecosystem to sustain humans (and other species).
A study released in November 2009 characterized the smart-growth policies in the U.S. state of Maryland as a failure, concluding that "there is no evidence after ten years that smart-growth have had any effect on development patterns."Lisa Rein, Study calls Md. smart growth a flop, The Washington Post, November 2, 2009Rebecca Lewis, Gerrit-Jan Knaap, and Jungyul Sohn, "Managing Growth With Priority Funding Areas: A Good Idea Whose Time Has Yet to Come," Journal of the American Planning Association, 75:4,457 — 478, Online Publication Date: September 1, 2009, Factors include a lack of incentives for builders to redevelop older neighborhoods and limits on the ability of state planners to force local jurisdictions to approve high-density developments in "smart-growth" areas. Buyers demand low-density development and voters tend to oppose high density developments near them.
Beginning in 2010, groups generally associated with the Tea Party movement began to identify Smart Growth as an outgrowth of the United Nations Agenda 21 which they viewed as an attempt by international interests to force a "sustainable" lifestyle on the United States. However planning groups and even some smart growth opponents counter that Smart Growth concepts and groups predate the 1992 Agenda 21 conference. In addition the word "sustainable development" as used in the Agenda 21 report is often misread to mean real estate development when it typically refers to the much broader concept of human development in the United Nations and foreign aid context which addresses a broader slate of economic, health, poverty, and education issues.
