Summary:
Since 1950 land development patterns in the United States have been dominated
by urban flight, suburban consumption of agricultural and natural areas,
auto dependency, and growing transportation gridlock from congestion.
In the last 10 years, architects and planners have responded with new,
more sustainable models of development intended to protect natural areas,
relieve auto dependency, and at the same time create more livable neighborhoods
and communities. These models are land-conserving, compact, walkable,
and often transit oriented; have mixed-income residential and commercial
uses; and set aside greenspace for recreation and environmental protection.
They also focus on revitalization of existing communities through infill,
brownfield, greyfield, and downtown redevelopment to create more livable
neighborhoods and town and city centers and relieve development pressure
on greenfield working landscapes and natural areas.
These sustainable models have grabbed the attention of government officials,
builders, and consumers alike. Government officials call it Smart Growth.
Builders and realtors call it green building and development. Designers
call it New Urbanism. Consumers call it livable communities.
The movement appears poised to take off. Projects carrying these various
labels are increasing exponentially. New Urbanism development projects
have grown from a handful five years ago to more than 400 according to
the inventory kept by the CNU. People are returning to live in center
cities and towns. Studies show a growing market for compact and walkable
neighborhoods as many empty nesters and young families are choosing the
walkable community and cultural life of cities and towns over the car-dependent
private isolation of the suburbs. The key elements of this movement include:
regional integration, conservation design of rural and greenfield development,
suburban revitalization, village and small-town development, and urban
infill and brownfield redevelopment.
Regional integration (think regional): The many new urbanism projects
are site specific, but solutions to sprawl require a regional perspective.
The region is the scale at which large metropolitan economic, ecological,
and social systems operate. Although the task of coordinating many, often
competing jurisdictions is a daunting one, it is critical for metropolitan
areas to achieve a regional identity and develop a regional growth plan
that includes growth centers and protection of environmental and working
landscapes. Calthorpes experience in the Twin Cities; Utahs
Wasatch Basin; Portland, Oregon; and other areas shows that not only is
such a plan possible, but it can be formulated through a participatory
planning process.
Neighborhood features (act local): Calthorpe and Fulton see the region
as the superstructure of human communities and neighborhoods as the substructure.
Neighborhoods are a regions ground-level social fabric and community
identity. The focus on the neighborhood scale is perhaps the greatest
contribution of the new design orientationcompactness, walkability,
mixed use, open space, natural drainage, community space.
Urban infill and brownfield redevelopment: A key to Smart Growth is taking
advantage of development opportunities in existing urban areas through
infill and brownfield redevelopment. The EPA estimates that development
of an acre of brownfields prevents development of 21 acres of greenfields.
In addition, the contamination and aesthetic blight of brownfields and
other vacant properties detract from the integrity of communities, preventing
other investments. Redevelopment not only heals the sores of the city
but also acts to cure other social and economic ailments by spurring medicinal
investment in surrounding properties.
Village and small-town development and revitalization: A regions
villages and small towns serve as critical nodes for revitalization and
development, building on existing culture and physical infrastructure.
Like urban infill, small-town revitalization relieves development pressure
on greenfields.
Suburban revitalization: Suburbs can become more livable communities through
revitalization projects, such as shopping center greyfield redevelopment,
infill with traditional neighborhoods, mixed use, and transit connections.
Rural and greenfield development: Despite existing community revitalization,
development of some greenfield areas is necessary. Arendt and others have
shown that rural development can occur while protecting working and natural
landscapes. This requires cluster housing and permanent protection and
management of agricultural, forestry, wetlands, and other sensitive lands.
Chapter 6 Discussion Questions:
1. "New Urbanism" is a label attached to a current movement
in land development design that aims to incorporate traditional compact
and walkable neighborhood features to create more community oriented developments.
Characterize New Urbanism and its variations in your own words and critique
it from the perspective of the elements of environmentally and community
sensitive design and development given in Table 6.2. Use information in
Chapter 6 and related links and references as needed.
2. Chapter 6 reviews the recent environmental land development design
work and concepts of Michael Corbett, Peter Calthorpe, Andres Duany, and
Randall Arendt among others. List three design concepts from their collective
work and briefly describe how these concepts contribute to "environmentally
and community sensitive development design."
3. While there are many advocates of the New urbanism movement, there
are critics as well. Critique is important for social movements in an
effort to make them more responsive to the needs of society. Some of the
criticisms of New Urbanism were raised in this chapter but not explored
in depth: affordability, rigid design standards that do not foster innovation,
location, access to transit and jobs. The critical literature on New Urbanism
is growing, often with accompanying debate among critics and advocates.
Find three sources of critical assessment of New Urbanism on the Internet
and write a one-page review of the critique and response.
Chapter 6 Exercises:
1. Explore the Congress for New Urbanism and New Urbanism News websites
(www.cnu.com and www.newurbannews.com) and select three to five examples
of New Urbanism developments. Describe the projects in terms of land area,
number of units, amount of open space, mixed income housing, mixed use
development, walkability, transit orientation, and others indicators of
livable communities.
2. Explore websites of Calthorpe Associates; Duany, Plater-Zyberk and
Company; and other related design firms and select one project each that
exemplifies their work. Compare the projects to the elements of environmentally
and sensitive community design given in Table 6.2 and to each other.
3.
Explore the photo simulation library of Steve Price at Urban Advantage (www.urban-advantage.com),
select some images and download them to a short powerpoint presentation
showing community design possibilities that incorporate the elements of
environmentally and sensitive community design given in Table 6.2.
4. For your state, describe the operable state programs for Brownfields
redevelopment. Idnetify three Brownfields projects and compare them in a
table showing prior use, future/present use, partners involved, level of
investment, government financial incentives, environmental remediation necessary,
economic, social and environmental benefits.
5. How do you distinguish between "green building" and "green
development"? Explore green building and green development sites on
the Internet and
6. Identify two different housing designs characterized as "green"
and in a table compare their specific features for energy and water conservation,
use of renewable energy, use of environmentally friendly materials, control
of indoor air quality, and construction and maintenance cost.
7. Identify two local government or trade association green building programs
and in a table compare them in terms of their approach, methods, design
criteria, and market penetration.
8. Identify two "green development" projects that have been built
and compare them in terms of the criteria for environmentally and community-sensitive
design, development, and land use practices given on page 111 of chapter
6.
9. The figures below describe a hypothetical conventional "yield"
plan showing a layout of the number of development units allowed for 70-acre,
mostly wooded site. Also shown is an environmental inventory showing sensitive
areas of the site. Using Randall Arendts approach, describe graphically
on the figure (or in a new one) and in words, the "buildable area"
and an improved "conservation design" for the site which provides
the same number of development units. (add graphics)
