Foundry Square is a complex of four architecturally-linked, 10-story mid-rise buildings located at Howard and First Streets near the Salesforce Transit Center in the South of Market neighborhood of San Francisco , California . Each of the four buildings stands on a different corner of the street.
90-401: Each building is a mixed-use structure. The four structures combined provide a total interior area of 1,200,000 square feet (110,000 m). The design team included STUDIOS Architecture, Jim Jennings Architecture, Page & Turnbull, Webcor Builders , and landscape architect SWA Group. The developer was Wilson Equity Office (now Wilson Meany). The Glazing Contractor used on these buildings
180-592: A block or neighborhood, or in zoning policy across an entire city or other administrative unit. These projects may be completed by a private developer, (quasi-)governmental agency, or a combination thereof. A mixed-use development may be a new construction, reuse of an existing building or brownfield site , or a combination. Traditionally, human settlements have developed in mixed-use patterns. However, with industrialization , governmental zoning regulations were introduced to separate different functions, such as manufacturing, from residential areas. Public health concerns and
270-542: A catalyst for economic growth, may not serve their intended purpose if they simply shift economic activity, rather than create it. A study done by Jones Lang LaSalle Incorporated (JLL) found that "90 percent of Hudson Yards' new office tenants relocated from Midtown." Some of the more frequent mixed-use scenarios in the United States are: The first large-scale attempt to create mixed-use development in Australia
360-716: A city can be impacted by mixed-use development. With the EPA putting models in the spreadsheet, it makes it much easier for municipalities, and developers to estimate the traffic, with Mixed-use spaces. The linking models also used as a resource tool measures the geography, demographics, and land use characteristics in a city. The Environmental Protection Agency has conducted an analysis on six major metropolitan areas using land usage, household surveys, and GIS databases. States such as California, Washington, New Mexico, and Virginia have adopted this standard as statewide policy when assessing how urban developments can impact traffic. Preconditions for
450-579: A combination of public and private interests, do not show a decrease in carbon emissions in comparison to metropolitan areas that have a low, dense configuration. This is possibly because hybrid metropolises are prone to attract car traffic from visitors. Due to the speculative nature of large scale real estate developments, mega-mixed-use projects often fall short on meeting equity and affordability goals. High-end residential, upscale retail, and Class A office spaces appealing to high-profile tenants are often prioritized due to their speculative potential. There
540-442: A destructive pattern of growth in an endless quest to move away from the sprawl that only results in creating more of it. Urban sprawl is associated with a number of negative environmental outcomes. One of the major environmental problems associated with sprawl is land consumption , habitat loss and subsequent reduction in biodiversity . A review by Brian Czech and colleagues finds that urbanization endangers more species and
630-664: A growing trend in America's metropolitan areas. The Brookings Institution has published multiple articles on the topic. In 2005, author Michael Stoll defined job sprawl simply as jobs located more than 5-mile (8.0 km) radius from the CBD, and measured the concept based on year 2000 U.S. Census data. Other ways of measuring the concept with more detailed rings around the CBD include a 2001 article by Edward Glaeser and Elizabeth Kneebone's 2009 article, which show that sprawling urban peripheries are gaining employment while areas closer to
720-627: A pejorative way. According to the National Resources Inventory (NRI), about 44 million acres (69,000 sq mi; 180,000 km ) of land in the United States was developed between 1982 and 2017. Presently, the NRI classifies approximately 100,000 more square kilometres (40,000 square miles) (an area approximately the size of Kentucky ) as developed than the Census Bureau classifies as urban. The difference in
810-408: A planning approach and those advocating the efficiency of the market". Those who criticize sprawl tend to argue that sprawl creates more problems than it solves and should be more heavily regulated, while proponents argue that markets are producing the economically most efficient settlements possible in most situations, even if problems may exist. However, some market-oriented commentators believe that
900-446: A result, the places where people live, work, shop, and recreate are far from one another, usually to the extent that walking, transit use and bicycling are impractical, so all these activities generally require a car. The degree to which different land uses are mixed together is often used as an indicator of sprawl in studies of the subject. According to this criterion, China's urbanization can be classified as "high-density sprawl",
990-417: A role in 1986 with a zoning bylaw that allowed for commercial and residential units to be mixed. At the time, Toronto was in the beginning stages of planning a focus on developing mixed-use development due to the growing popularity of more social housing. The law has since been updated as recently as 2013, shifting much of its focus outside the downtown area which has been a part of the main city since 1998. With

#17327808099981080-429: A seemingly self-contradictory term coined by New Urbanist Peter Calthorpe . He explains that despite the high-rise buildings, China's superblocks (huge residential blocks) are largely single-use and surrounded by giant arterial roads, which detach different functions of a city and create an environment unfriendly to pedestrians. Job sprawl is another land use symptom of urban sprawl and car-dependent communities. It
1170-509: A significant focus on affordable housing provisions in these plans. Mixed-use buildings can be risky given that there are multiple tenants residing in one development. Mega-mixed-use projects, like Hudson Yards , are also extremely expensive. This development has cost the City of New York over 2.2 billion dollars. Critics argue that taxpayer dollars could better serve the general public if spent elsewhere. Additionally, mixed-use developments, as
1260-618: A significant intersection in Toronto, portions of the Mirvish Village project site are zoned as "commercial residential" and others as "mixed commercial residential". Within the City of Toronto's zoning by-laws, commercial residential includes "a range of commercial, residential and institutional uses, as well as parks." Mirvish Village's programmatic uses include rental apartments, a public market, and small-unit retail, while also preserving 23 of 27 heritage houses on site. The project
1350-569: A strong ability to adapt to changing social and economic environments. When the COVID-19 pandemic hit, New York retailers located on long, commercially oriented blocks suffered severely as they were no longer attracting an audience of passersby. By combining multiple functions into one building or development, mixed-use districts can build resiliency through their ability to attract and maintain visitors. More sustainable transportation practices are also fostered. A study of Guangzhou, China , done by
1440-417: Is a natural product of population increases, higher wages, and therefore better access to housing. Improvement in transportation also means that individuals are able to live further from large cities and industrial hubs, thus increasing demand for better housing further from the noise of cities. This leads to the creation of sprawling residential land development surrounding densely packed urban areas. Despite
1530-405: Is a type of urban development , urban design , urban planning and/or a zoning classification that blends multiple uses , such as residential, commercial, cultural, institutional, or entertainment, into one space, where those functions are to some degree physically and functionally integrated, and that provides pedestrian connections. Mixed-use development may be applied to a single building,
1620-618: Is also a trend towards making residential spaces in mixed-use developments to be condominiums, rather than rental spaces. A study done by the Journal of the American Planning Association found that a focus on homeownership predominantly excludes individuals working in public services, trades, cultural, sales and service, and manufacturing occupations from living in amenity-rich city centers. Despite incentives like density bonuses, municipalities and developers rarely put
1710-462: Is also absent in Germany and Russia where zoning codes make no distinction between different types of housing. America's attachment to private property and the traditional 1950s suburban home, as well as deep racial and class divides, have marked the divergence in mixed-use zoning between the continents. As a result, much of Europe's central cities are mixed use "by default" and the term "mixed-use"
1800-535: Is also found in these districts. This development pattern is centered around the idea of "live, work, play," transforming buildings and neighborhoods into multi-use entities. Efficiency, productivity, and quality of life are also increased with regards to workplaces holding a plethora of amenities. Examples include gyms, restaurants, bars, and shopping. Mixed-use neighborhoods promote community and socialization through their bringing together of employees, visitors, and residents. A distinctive character and sense-of-place
1890-479: Is argued that human beings, while social animals, need significant amounts of social space or they become agitated and aggressive. However, the relationship between higher densities and increased social pathology has been largely discredited. According to Nancy Chin, a large number of effects of sprawl have been discussed in the academic literature in some detail; however, the most contentious issues can be reduced "to an older set of arguments, between those advocating
SECTION 20
#17327808099981980-576: Is commonly linked to increased dependency on cars. In 2003, a British newspaper calculated that urban sprawl would cause an economic loss of £3,905 per year, per person through cars alone, based on data from the RAC estimating that the average cost of operating a car in the UK at that time was £5,000 a year, while train travel (assuming a citizen commutes every day of the year, with a ticket cost of 3 pounds) would be only £1,095. Additionally, increased density increases
2070-399: Is created by transforming single use districts that may run for eight hours a day (ex. commercial office buildings running 9am - 5pm) into communities that can run eighteen hours a day through the addition of cafes, restaurants, bars, and nightclubs. Safety of neighborhoods in turn may be increased as people stay out on the streets for longer hours. Mixed-use neighborhoods and buildings have
2160-431: Is defined as "the spreading of urban developments (such as houses, dense multi–family apartments, office buildings and shopping centers) on undeveloped land near a more or less densely populated city". Urban sprawl has been described as the unrestricted growth in many urban areas of housing, commercial development, and roads over large expanses of land, with little concern for very dense urban planning . Sometimes
2250-571: Is defined as low-density, geographically spread-out patterns of employment, where the majority of jobs in a given metropolitan area are located outside of the main city's central business district (CBD), and increasingly in the suburban periphery. It is often the result of urban disinvestment , the geographic freedom of employment location allowed by predominantly car-dependent commuting patterns of many American suburbs, and many companies' desire to locate in low-density areas that are often more affordable and offer potential for expansion. Spatial mismatch
2340-414: Is defined by negative characteristics. What constitutes sprawl may be considered a matter of degree and will always be somewhat subjective under many definitions of the term. Ewing has also argued that suburban development does not, per se , constitute sprawl depending on the form it takes, although Gordon & Richardson have argued that the term is sometimes used synonymously with suburbanization in
2430-511: Is due. Thus urban sprawl is subsidized by the tax code. In China, land has been converted from rural to urban use in advance of demand, leading to vacant rural land intended for future development, and eventual urban sprawl. Housing subdivisions are large tracts of land consisting entirely of newly built residences. New Urbanist architectural firm Duany Plater-Zyberk & Company state that housing subdivisions "are sometimes called villages, towns, and neighbourhoods by their developers, which
2520-684: Is in contrast to New York, San Francisco or Chicago which have compact, high-density cores surrounded by areas of very low-density suburban periphery, such as eastern Suffolk County in the New York metro area and Marin County in the San Francisco Bay Area . Some cases of sprawl challenge the definition of the term and what conditions are necessary for urban growth to be considered sprawl. Metropolitan regions such as Greater Mexico City , Delhi National Capital Region Beijing , and
2610-422: Is incentivized in these regions. By taking undervalued and underutilized land, often former heavy industrial, developers can repurpose it to increase land and property values. These projects also increase housing variety, density, and oftentimes affordability through their focus on multifamily, rather than single-family housing compounds. A more equal balance between the supply and demand of jobs and housing
2700-422: Is misleading since those terms denote places that are not exclusively residential". They are also referred to as developments. Subdivisions often incorporate curved roads and cul-de-sacs . These subdivisions may offer only a few places to enter and exit the development, causing traffic to use high volume collector streets. All trips, no matter how short, must enter the collector road in a suburban system. After

Urban sprawl is disruptive to native flora & fauna and introduces invasive plants into their environments. Although the effects can be mitigated through careful maintenance of native vegetation, the process of ecological succession and public education, sprawl represents one of the primary threats to biodiversity. Regions with high birth rates and immigration are therefore faced with environmental problems due to unplanned urban growth and emerging megacities such as Kolkata. Other problems include: At

2880-717: Is much more relevant regarding new areas of the city where an effort is made to mix residential and commercial activities – such as in Amsterdam's Eastern Docklands . Expanded use of mixed-use zoning and mixed-use developments may be found in a variety of contexts, such as the following (multiple such contexts might apply to one particular project or situation): Any of the above contexts may also include parallel contexts such as: Mixed-use developments are home to significant employment and housing opportunities. Many of these projects are already located in established downtown districts, meaning that development of public transit systems

Architect Henriquez and the developer had previously collaborated on mixed-use projects in Vancouver , British Columbia , including the successful Woodward's Redevelopment . In the United States, the Environmental Protection Agency (EPA) collaborates with local governments by providing researchers developing new data that estimates how

Bhatta et al. wrote in 2010 that despite a dispute over the precise definition of sprawl, there is a "general consensus that urban sprawl is characterized by [an] unplanned and uneven pattern of growth, driven by a multitude of processes and leading to inefficient resource utilization". Reid Ewing has shown that sprawl has typically been characterized as urban developments exhibiting at least one of

Spatial mismatch is defined as the situation where poor urban, predominantly minority citizens are left without easy access to entry-level jobs, as a result of increasing job sprawl and limited transportation options to facilitate a reverse commute to the suburbs. Job sprawl has been documented and measured in various ways. It has been shown to be

Unlike the strip mall, this is usually composed of a single building surrounded by a parking lot that contains multiple shops, usually "anchored" by one or more department stores . The function and size is also distinct from the strip mall. The focus is almost exclusively on recreational shopping rather than daily goods. Shopping malls also tend to serve a wider (regional) public and require higher-order infrastructure such as highway access and can have floorspaces in excess of 1 million sq ft (93,000 m ). Shopping malls are often detrimental to downtown shopping centres of nearby cities since
3330-621: Is the US's largest project to ever be financed by TIF ( tax increment financing ) subsidies. It did not require voter approval, nor did it have to go through the city's traditional budgeting process. Rather, the project is financed by future property taxes and the EB-5 Visa Program. This program provides VISAs to overseas investors in exchange for placing a minimum of $ 500,000 into US real estate. Urban sprawl Urban sprawl (also known as suburban sprawl or urban encroachment )
3420-826: The Cato Institute , a libertarian think tank , has argued that sprawl, thanks to the automobile, gave rise to affordable suburban neighborhoods for middle class and lower class individuals, including non-whites. He notes that efforts to combat sprawl often result in subsidizing development in wealthier and whiter neighborhoods while condemning and demolishing poorer minority neighborhoods. The American Institute of Architects , American Planning Association , and Smart Growth America recommend against sprawl and instead endorses smart , mixed-use development , including buildings in close proximity to one another that cut down on automobile use, save energy, and promote walkable, healthy, well-designed neighborhoods. The Sierra Club ,
3510-716: The Greater Tokyo Area are often regarded as sprawling despite being relatively dense and mixed use. Many theories speculate as to the reason for the creation of urban sprawl. The theory of "flight from blight" explains that aspects of living in urban areas, such as high taxes, crime rates, poor infrastructure and school qualities lead to many people moving out of urban areas and into surrounding suburban areas. According to The Limits to Growth , reasons why wealthier people move to suburbs include noise, pollution, crime, drug addiction, poverty, labor strikes, and breakdown of social services. Others suggest that Urban Sprawl
3600-485: The San Francisco Chronicle described as "Downtown San Francisco['s] worst office vacancy crisis on record," Foundry Square IV (500 Howard Street) had a vacancy rate of 95.4% and Foundry Square III (505 Howard Street) had a vacancy rate of 97.6%, compared to 1.6% for Foundry Square II (405 Howard Street) and 36.9 % for Foundry Square I (400 Howard Street). Mixed-use development Mixed use

The development of country clubs and golf courses in the early 20th century further promoted lawn culture in the United States. Lawns now take up a significant amount of land in suburban developments, contributing to sprawl. In areas of sprawl, commercial use is generally segregated from other uses. In

3780-415: The urban areas described as the most "sprawling" are the most densely populated. In addition to describing a special form of urbanization , the term also relates to the social and environmental consequences associated with this development. In modern times some suburban areas described as "sprawl" have less detached housing and higher density than the nearby core city . Medieval suburbs suffered from
3870-532: The 10–35 mile ring. This compares to the year 1998 – 23.3%, 34.2%, and 42.5% in those respective rings. The study shows CBD employment share shrinking, and job growth focused in the suburban and exurban outer metropolitan rings. Sprawl often refers to low- density development . There is no precise definition of "low density", but it might commonly mean Single-family homes on large lots. Such buildings usually have fewer stories and are spaced farther apart, separated by lawns , landscaping , roads or parking lots. In
3960-472: The 1960s. Since the 1990s, mixed-use zoning has once again become desirable as it works to combat urban sprawl and increase economic vitality. In most of Europe, government policy has encouraged the continuation of the city center's role as a main location for business, retail, restaurant, and entertainment activity, unlike in the United States where zoning actively discouraged such mixed use for many decades. In England, for example, hotels are included under

These two authors used three geographic rings limited to a 35-mile (56 km) radius around the CBD: 3 miles (4.8 km) or less, 3 to 10 miles (16 km), and 10 to 35 miles (56 km). Kneebone's study showed the following nationwide breakdown for the largest metropolitan areas in 2006: 21.3% of jobs located in the inner ring, 33.6% of jobs in the 3–10 mile ring, and 45.1% in
4140-790: The Journal of Geographical Information Science, found that taxis located in regions where buildings housed a greater variety of functions had greatly reduced traveling distances. Shorter traveling distances, in turn, support the use of micro-mobility . Pedestrian and bike-friendly infrastructure are fostered due to increased density and reduced distances between housing, workplaces, retail businesses, and other amenities and destinations. Additionally, mixed-use projects promote health and wellness, as these developments often provide better access (whether it be by foot, bicycle, or transit) to farmer's markets and grocery stores. However, hybrid metropolises, areas that have large and tall buildings which accommodate
4230-546: The NRI classification is that it includes rural development, which by definition cannot be considered to be "urban" sprawl. Currently, according to the 2000 Census , approximately 2.6 percent of the U.S. land area is urban. Approximately 0.8 percent of the nation's land is in the 37 urbanized areas with more than 1,000,000 population. In 2002, these 37 urbanized areas supported around 40% of the total American population. Nonetheless, some urban areas like Detroit have expanded geographically even while losing population. But it

NumbersUSA , a national organization advocating immigration reduction , also opposes urban sprawl, and its founder, Roy Beck , specializes in the study of this issue. One of
4410-513: The U.S. and Canada, these often take the form of strip malls , which refer to collections of buildings sharing a common parking lot, usually built on a high-capacity roadway with commercial functions (i.e., a "strip"). Similar developments in the United Kingdom are called Retail Parks. Strip malls consisting mostly of big box stores or category killers are sometimes called "power centers" (U.S.). These developments tend to be low-density;
4500-457: The United States came after World War II when planner and New York City Parks Commissioner , Robert Moses , championed superhighways to break up functions and neighborhoods of the city. The antithesis to these practices came from activist and writer, Jane Jacobs , who was a major proponent of mixed-use zoning, believing it played a key role in creating an organic, diverse, and vibrant streetscape. These two figures went head-to-head during much of
4590-450: The United States 2–4 houses per acre (5–10 per hectare) might be considered low-density while in the UK 8–12 per acre (or 20–30 per hectare) would still be considered low-density. Because more automobiles are used in the USA, much more land is designated for parking. The impact of low density development in many communities is that developed or "urbanized" land is increasing at a faster rate than

Others associate it with decentralization (spread of population without a well-defined centre), discontinuity ( leapfrogging development, as defined below ), segregation of uses, and so forth. The term urban sprawl is highly politicized and almost always has negative connotations. It is criticized for causing environmental degradation , intensifying segregation , and undermining
4770-526: The buildings are single-story and there is ample space for parking and access for delivery vehicles. This character is reflected in the spacious landscaping of the parking lots and walkways and clear signage of the retail establishments. Some strip malls are undergoing a transformation into Lifestyle centers ; entailing investments in common areas and facilities (plazas, cafes) and shifting tenancy from daily goods to recreational shopping. Another prominent form of retail development in areas characterized by sprawl
4860-478: The chance that people will take the bicycle for their commute which would be better for their health. Bicycles are a common mode of transportation for those living in urban centers due to many factors. One major factor many people consider relates to how, when one rides a bike to, say, their workplace, they are exercising as they do so. This multi-tasking is better for one's health than automatic transport. A heavy reliance on automobiles increases traffic throughout
4950-491: The city as well as automobile crashes, pedestrian injuries, and air pollution. Motor vehicle crashes are the leading cause of death for Americans between the ages of five and twenty-four and is the leading accident-related cause for all age groups. Residents of more sprawling areas are generally at greater risk of dying in a car crash due to increased exposure to driving. Evidence indicates that pedestrians in sprawling areas are at higher risk than those in denser areas, although
5040-454: The conversion of agricultural land to urban use is not a problem due to the increasing efficiency of agricultural production; they argue that aggregate agricultural production is still more than sufficient to meet global food needs despite the expansion of urban land use. Sprawl leads to increased driving, which in turn leads to vehicle emissions that contribute to air pollution and its attendant negative impacts on human health . In addition,
5130-611: The current custom of requiring a developer to provide subdivision infrastructure as a condition of development. Usually, the developer is required to set aside a certain percentage of the developed land for public use, including roads, parks and schools. In the past, when a local government built all the streets in a given location, the town could expand without interruption and with a coherent circulation system, because it had condemnation power . Private developers generally do not have such power (although they can sometimes find local governments willing to help), and often choose to develop on
5220-703: The current patterns of sprawl are in fact the result of distortions of the free market. Chin cautions that there is a lack of "reliable empirical evidence to support the arguments made either for or against sprawl". She mentions that the lack of a common definition, the need for more quantitative measures "a broader view both in time and space, and greater comparison with alternative urban forms" would be necessary to draw firmer conclusions and conduct more fruitful debates. Arguments opposing urban sprawl include concrete effects such as health and environmental issues as well as abstract consequences including neighborhood vitality. American public policy analyst Randal O'Toole of
5310-492: The desirability of the area adjacent to such structures. Providing services such as water , sewers , road maintenance, and electricity is also more expensive per household in less dense areas, given that sprawl increases lengths of power lines, roads, and pipes, necessitating higher maintenance costs. Residents of low-density areas spend a higher proportion of their income on transportation than residents of high density areas. The unplanned nature of outward urban development
5400-484: The dismantling of infrastructure that occurred in the United States. Despite its sprawl, Metropolitan Los Angeles is the densest major urban area (over 1,000,000 population) in the US, being denser than the New York urban area and the San Francisco urban area. Most of metropolitan Los Angeles is built at more uniform low to moderate density, leading to a much higher overall density for the entire region. This

The Metropolitan Area Express , Portland's light rail system, encourages the mixing of residential, commercial, and work spaces into one zone. With this one-zoning-type planning system, the use of land at increased densities provides a return in public investments throughout the city. Main street corridors provide flexible building heights and high density uses to enable "gathering places". Hudson Yards project

In the United States the seller may avoid tax on profit by using a tax break exempting like-kind exchanges from capital gains tax ; proceeds from the sale are used to purchase agricultural land elsewhere and the transaction is treated as a "swap" or trade of like assets and no tax
5670-496: The following characteristics: low-density or single-use development, strip development, scattered development, and/or leapfrog development (areas of development interspersed with vacant land). He argued that a better way to identify sprawl was to use indicators rather than characteristics because this was a more flexible and less arbitrary method. He proposed using " accessibility " and "functional open space" as indicators. Ewing's approach has been criticized for assuming that sprawl

In particular, the 1988 Plan was designed in collaboration with a transport strategy and was the first to recommend higher development densities. Since then, Australian planning authorities have given greater priority to mixed-use development of inner-city industrial land as a way of revitalising areas neglected by the decline in manufacturing, consolidating and densifying
5850-426: The lack of a clear agreed upon description of what defines sprawl most definitions often associate the following characteristics with sprawl. This refers to a situation where commercial, residential , institutional and industrial areas are separated from one another. Consequently, large tracts of land are devoted to a single use and are segregated from one another by open space, infrastructure, or other barriers. As
5940-593: The larger area consumed by sprawling suburbs compared to urban neighborhoods, more farmland and wildlife habitats are displaced per resident. As forest cover is cleared and covered with impervious surfaces ( concrete and asphalt ) in the suburbs, rainfall is less effectively absorbed into the groundwater aquifers . This threatens both the quality and quantity of water supplies. Sprawl increases water pollution as rain water picks up gasoline , motor oil , heavy metals , and other pollutants in runoff from parking lots and roads. Gordon & Richardson have argued that

Modern disadvantages and costs include increased travel time, transport costs, pollution, and destruction of the countryside. The revenue for building and maintaining urban infrastructure in these areas are gained mostly through property and sales taxes. Most jobs in the US are now located in suburbs generating much of

Furthermore, they state that the closeness of the workplace to homes also gives people the option of walking or riding a bicycle to work or school and that without this kind of interaction between the different components of life
6210-435: The population is growing. Overall density is often lowered by " leapfrog development". This term refers to the relationship, or lack of it, between subdivisions. Such developments are typically separated by large green belts , i.e. tracts of undeveloped land, resulting in an overall density far lower even than the low density indicated by localized per-acre measurements. This is a 20th and 21st century phenomenon generated by

This new urban planning approach has had a significant impact on the use of land parcels in major Australian cities: according to 2021 data from Australian Bureau of Statistics , mixed zoning already suppose more than 9% of new housing approvals. One of the first cities to adopt a policy on mixed-use development is Toronto . The local government first played
6390-441: The protection of property values stood as the motivation behind this separation. In the United States, the practice of zoning for single-family residential use was instigated to safeguard communities from negative externalities , including air, noise, and light pollution, associated with heavier industrial practices. These zones were also constructed to alleviate racial and class tensions. The heyday of separate-use zoning in

Sprawl significantly predicts chronic medical conditions and health-related quality of life, but not mental health disorders. The American Journal of Public Health and the American Journal of Health Promotion, have both stated that there is a significant connection between sprawl, obesity , and hypertension . Loud vehicles can cause stress, prevent sleep, and minimize social interactions in public for people living in cities (especially homeless people). In

Toronto's policies of mixed-use development have inspired other North American cities in Canada and the United States to bring about similar changes. One example of a Toronto mixed-use development is Mirvish Village by architect Gregory Henriquez . Located at Bloor and Bathurst Street ,
6660-603: The relationship is less clear than for drivers and passengers in vehicles. Research covered in the Journal of Economic Issues and State and Local Government Review shows a link between sprawl and emergency medical services response and fire department response delays. Living in larger, more spread out spaces generally makes public services more expensive. Since car usage becomes endemic and public transport often becomes significantly more expensive, city planners are forced to build highway and parking infrastructure , which in turn decreases taxable land and revenue, and decreases
6750-509: The revenue, although a lack of growth will require higher tax rates. In Europe , the term peri-urbanisation is often used to denote similar dynamics and phenomena, but the term urban sprawl is currently being used by the European Environment Agency . There is widespread disagreement about what constitutes sprawl and how to quantify it. For example, some commentators measure sprawl by residential density , using
6840-477: The same time, the urban cores of these and nearly all other major cities in the United States , Western Europe , and Japan that did not annex new territory experienced the related phenomena of falling household size and, particularly in the U.S., " white flight ", sustaining population losses. This trend has slowed somewhat in recent years, as more people have regained an interest in urban living. Due to
6930-405: The same umbrella as "residential," rather than commercial as they are classified under in the US. France similarly gravitates towards mixed-use as much of Paris is simply zoned to be "General Urban," allowing for a variety of uses. Even zones that house the mansions and villas of the aristocrats focus on historical and architectural preservation rather than single family zoning. Single family zoning
7020-628: The shopping malls act as a surrogate for the city centre . Some downtowns have responded to this challenge by building shopping centres of their own. Fast food chains are often built early in areas with low property values where the population is expected to boom and where large traffic is predicted, and set a precedent for future development. Eric Schlosser , in his book Fast Food Nation , argues that fast food chains accelerate suburban sprawl and help set its tone with their expansive parking lots, flashy signs, and plastic architecture (65). Duany Plater Zyberk & Company believe that this reinforces
7110-566: The square, establishing an arcade that defines the transition between interior building space and public exterior spaces. The four corners of the intersection are integrated by the use of public art and sculpture (such as Richard Deutsch 's "Time Signature" stainless steel sculpture), tree bosques , ground-floor cafes, and over-scaled pots. The project earned SWA Group the ASLA Northern California Chapter Merit Award in 2006. As of May 2023, during what
7200-463: The success of mixed-use developments are employment, population, and consumer spending . The three preconditions ensure that a development can attract quality tenants and financial success. Other factors determining the success of the mixed-use development is the proximity of production time, and the costs from the surrounding market. Mixed-use zoning has been implemented in Portland, Oregon , since
7290-573: The supply of housing in desirable areas, and thus, it also decreases housing prices in those areas (by the logic of supply and demand ). Urban sprawl may be partly responsible for the decline in social capital in the United States. Compact neighborhoods can foster casual social interactions among neighbors, while sprawl creates barriers. Sprawl tends to replace public spaces with private spaces such as fenced-in backyards. Critics of sprawl maintain that sprawl erodes quality of life . Duany and Plater-Zyberk believe that in traditional neighborhoods
7380-411: The tracts that happen to be for sale at the time they want to build, rather than pay extra or wait for a more appropriate location. Some research argues that religious ideas about how humans should live (and die) promote low-density development and may contribute to urban sprawl. Land for sprawl is often taken from fertile agricultural lands , which are often located immediately surrounding cities;
7470-603: The urban pattern quickly falls apart. James Howard Kunstler has argued that poor aesthetics in suburban environments make them "places not worth caring about", and that they lack a sense of history and identity. Urban sprawl has class and racial implications in many parts of the world; the relative homogeneity of many sprawl developments may reinforce class and racial divides through residential segregation . Numerous studies link increased population density with increased aggression. Some people believe that increased population density encourages crime and anti-social behavior. It
7560-419: The vitality of existing urban areas, and is attacked on aesthetic grounds. The pejorative meaning of the term means that few openly support urban sprawl as such. The term has become a rallying cry for managing urban growth. The term urban sprawl was often used in the letters between Lewis Mumford and Frederic J. Osborn, firstly by Osborn in his 1941 letter to Mumford and later by Mumford, generally condemning
7650-512: The waste of agricultural land and landscape due to suburban expansions. The term was used in an article in The Times in 1955 as a negative comment on the state of London 's outskirts. Definitions of sprawl vary; researchers in the field acknowledge that the term lacks precision. Batty et al. defined sprawl as "uncoordinated growth: the expansion of community without concern for its consequences, in short, unplanned, incremental urban growth which
7740-603: The years following World War II, when vehicle ownership was becoming widespread, public health officials recommended the health benefits of suburbs due to soot and industrial fumes in the city center. However, air in modern suburbs is not necessarily cleaner than air in urban neighborhoods. In fact, the most polluted air is on crowded highways, where people in suburbs tend to spend more time. On average, suburban residents generate more per capita pollution and carbon emissions than their urban counterparts because of their increased driving, as well as larger homes. Sprawl also reduces
7830-490: Was AGA (Architectural Glass and Aluminum) . Current tenants include the law firm of Orrick, Herrington & Sutcliffe , STUDIOS Architecture, the headquarters of Slack , and the NASDAQ Entrepreneurial Center. The project's first phase, Foundry Square II (405 Howard Street) and Foundry Square IV (500 Howard Street), was completed in 2003. The third building, Foundry Square I (400 Howard Street),
7920-562: Was completed in 2007. In April 2012, Tishman Speyer acquired the entitlements to the final building, Foundry Square III (505 Howard Street), from Wilson Meany Sullivan, and broke ground later that year. Foundry Square III was completed in April 2014. The 1,000 square feet (93 m) contained within Foundry Square's four open corners form a larger, unified public square. Each building's 200-foot (61 m) dual-glaze glass walls frame
8010-496: Was not just urbanized areas in the U.S. that lost population and sprawled substantially. According to data in "Cities and Automobile Dependence" by Kenworthy and Laube (1999), urbanized area population losses occurred while there was an expansion of sprawl between 1970 and 1990 in Amsterdam , Netherlands; Brussels , Belgium; Copenhagen , Denmark; Frankfurt , Hamburg and Munich , Germany; and Zürich , Switzerland, albeit without
8100-670: Was the Sydney Region Outline Plan , a plan that identified Sydney 's need to decentralise and organise its growth around the metropolitan area. Its main objective was to control the city's rapid post-war population growth by introducing growth corridors and economic centres that would help prevent uncontrolled sprawl and the overuse of the car as a means of transport Several city centres such as Parramatta or Campbelltown benefited from these policies, creating economic hubs with his own inner-city amenities along Sydney's main thoroughfares. Subsequent plans complemented
