Zoning: The method
used by cities to promote the compatibility of land uses by dividing tracts of
land within the city into different districts or zones. Zoning ensures that a
factory is not located in the middle of a residential neighborhood or that a
bar is not located next to an elementary school.

Principles of Smart Growth
Mix Land Uses
Smart growth supports the
integration of mixed land uses into communities as a critical component of achieving
better places to live. By putting uses in close proximity to one another,
alternatives to driving, such as walking or biking, once again become viable.
Mixed land uses also provides a more diverse and sizable population and
commercial base for supporting viable public transit. It can enhance the
vitality and perceived security of an area by increasing the number and
attitude of people on the street. It helps streets, public spaces and
pedestrian-oriented retail again become places where people meet, attracting
pedestrians back onto the street and helping to revitalize community life.
Mixed land uses can convey substantial fiscal and economic benefits. Commercial
uses in close proximity to residential areas are often reflected in higher
property values, and therefore help raise local tax receipts. Businesses
recognize the benefits associated with areas able to attract more people, as
there is increased economic activity when there are more people in an area to
shop. In today's service economy, communities find that by mixing land uses,
they make their neighborhoods attractive to workers who increasingly balance
quality of life criteria with salary to determine where they will settle. Smart
growth provides a means for communities to alter the planning context which
currently renders mixed land uses illegal in most of the country.
Take Advantage of Compact Building Design
Smart growth provides a means for communities to
incorporate more compact building design as an alternative to conventional,
land consumptive development. Compact building design suggests that communities
be designed in a way which permits more open space to preserved, and that
buildings can be constructed which make more efficient use of land and
resources. By encouraging buildings to grow vertically rather than
horizontally, and by incorporating structured rather than surface parking, for
example, communities can reduce the footprint of new construction, and preserve
more greenspace. Not only is this approach more efficient by requiring less
land for construction. It also provides and protects more open, undeveloped
land that would exist otherwise to absorb and filter rain water, reduce
flooding and stormwater drainage needs, and lower the amount of pollution washing
into our streams, rivers and lakes.
Compact building design is necessary to support wider transportation choices,
and provides cost savings for localities. Communities seeking to encourage
transit use to reduce air pollution and congestion recognize that minimum
levels of density are required to make public transit networks viable. Local
governments find that on a per-unit basis, it is cheaper to provide and
maintain services like water, sewer, electricity, phone service and other
utilities in more compact neighborhoods than in dispersed communities.
Research based on these developments has shown, for example, that
well-designed, compact New Urbanist communities that include a variety of house
sizes and types command a higher market value on a per square foot basis than
do those in adjacent conventional suburban developments. Perhaps this is why
increasing numbers of the development industry have been able to successfully
integrate compact design into community building efforts. This despite current zoning
practices – such as those that require minimum lot sizes, or prohibit
multi-family or attached housing – and other barriers - community perceptions
of “higher density” development, often preclude compact design.
Create Range of Housing Opportunities and Choices
Providing quality housing for people of all income levels is
an integral component in any smart growth strategy. Housing is a critical part
of the way communities grow, as it is constitutes a significant share of new
construction and development. More importantly, however, is also a key factor
in determining households’ access to transportation, commuting patterns, access
to services and education, and consumption of energy and other natural
resources. By using smart growth approaches to create a wider range of housing
choices, communities can mitigate the environmental costs of auto-dependent
development, use their infrastructure resources more efficiently, ensure a
better jobs-housing balance, and generate a strong foundation of support for
neighborhood transit stops, commercial centers, and other services.
No single type of housing can serve the varied needs of today’s diverse
households. Smart growth represents an opportunity for local communities to
increase housing choice not only by modifying their land use patterns on
newly-developed land, but also by increasing housing supply in existing
neighborhoods and on land served by existing infrastructure. Integrating
single- and multi-family structures in new housing developments can support a
more diverse population and allow more equitable distribution of households of
all income levels across the region. The addition of units -- through attached
housing, accessory units, or conversion to multi-family dwellings -- to
existing neighborhoods creates opportunities for communities to slowly increase
density without radically changing the landscape. New housing construction can
be an economic stimulus for existing commercial centers that are currently
vibrant during the work day, but suffer from a lack of foot traffic and
consumers in evenings or weekends. Most importantly, providing a range of
housing choices allow all households to find their niche in a smart growth
community – whether it is a garden apartment, a rowhouse, or a traditional
suburban home – and accommodate growth at the same time.
Create Walkable Neighborhoods
Walkable communities are desirable places to live, work,
learn, worship and play, and therefore a key component of smart growth. Their
desirability comes from two factors. First, walkable communities locate within
an easy and safe walk goods (such as housing, offices, and retail) and services
(such as transportation, schools, libraries) that a community resident or
employee needs on a regular basis. Second, by definition, walkable communities
make pedestrian activity possible, thus expanding transportation options, and
creating a streetscape that better serves a range of users -- pedestrians,
bicyclists, transit riders, and automobiles. To foster walkability, communities
must mix land uses and build compactly, and ensure safe and inviting pedestrian
corridors.
Walkable communities are nothing new. Outside of the last half-century
communities worldwide have created neighborhoods, communities, towns and cities
premised on pedestrian access. Within the last fifty years public and private
actions often present created obstacles to walkable communities. Conventional
land use regulation often prohibits the mixing of land uses, thus lengthening
trips and making walking a less viable alternative to other forms of travel.
This regulatory bias against mixed-use development is reinforced by private
financing policies that view mixed-use development as riskier than single-use
development. Many communities -- particularly those that are dispersed and
largely auto-dependent -- employ street and development design practices that
reduce pedestrian activity.
As the personal and societal benefits of pedestrian friendly communities are
realized – benefits which include lower transportation costs, greater social
interaction, improved personal and environmental health, and expanded consumer
choice -- many are calling upon the public and private sector to facilitate the
development of walkable places. Land use and community design plays a pivotal
role in encouraging pedestrian environments. By building places with multiple
destinations within close proximity, where the streets and sidewalks balance
all forms of transportation, communities have the basic framework for
encouraging walkability.
Foster Distinctive, Attractive Communities with a Strong Sense of Place
Smart growth encourages communities to craft a vision and set
standards for development and construction which respond to community values of
architectural beauty and distinctiveness, as well as expanded choices in
housing and transportation. It seeks to create interesting, unique communities
which reflect the values and cultures of the people who reside there, and
foster the types of physical environments which support a more cohesive
community fabric. Smart growth promotes development which uses natural and
man-made boundaries and landmarks to create a sense of defined neighborhoods,
towns, and regions. It encourages the construction and preservation of
buildings which prove to be assets to a community over time, not only because
of the services provided within, but because of the unique contribution they
make on the outside to the look and feel of a city.
Guided by a vision of how and where to grow, communities are able to identify
and utilize opportunities to make new development conform to their standards of
distinctiveness and beauty. Contrary to the current mode of development, smart
growth ensures that the value of infill and greenfield development is
determined as much by their accessibility (by car or other means) as their
physical orientation to and relationship with other buildings and open space.
By creating high-quality communities with architectural and natural elements
that reflect the interests of all residents, there is a greater likelihood that
buildings (and therefore entire neighborhoods) will retain their economic
vitality and value over time. In so doing, the infrastructure and natural
resources used to create these areas will provide residents with a distinctive
and beautiful place that they can call “home” for generations to come.
Preserve Open Space, Farmland, Natural Beauty and Critical Environmental Areas
Smart growth uses the term “open space” broadly to mean
natural areas both in and surrounding localities that provide important
community space, habitat for plants and animals, recreational opportunities,
farm and ranch land (working lands), places of natural beauty and critical
environmental areas (e.g. wetlands). Open space preservation supports smart
growth goals by bolstering local economies, preserving critical environmental
areas, improving our communities quality of life, and guiding new growth into
existing communities.
There is growing political will to save the "open spaces" that
Americans treasure. Voters in 2000 overwhelmingly approved ballot measures to
fund open space protection efforts. The reasons for such support are varied and
attributable to the benefits associated with open space protection. Protection
of open space provides many fiscal benefits, including increasing local
property value (thereby increasing property tax bases), providing tourism
dollars, and decreases local tax increases (due to the savings of reducing the
construction of new infrastructure). Management of the quality and supply of
open space also ensures that prime farm and ranch lands are available, prevents
flood damage, and provides a less expensive and natural alternative for
providing clean drinking water.
The availability of open space also provides significant environmental quality
and health benefits. Open space protects animal and plant habitat, places of
natural beauty, and working lands by removing the development pressure and
redirecting new growth to existing communities. Additionally, preservation of
open space benefits the environment by combating air pollution, attenuating
noise, controlling wind, providing erosion control, and moderating
temperatures. Open space also protects surface and ground water resources by
filtering trash, debris, and chemical pollutants before they enter a water
system.
Strengthen and Direct Development Towards Existing Communities
Smart growth directs development towards existing communities
already served by infrastructure, seeking to utilize the resources that
existing neighborhoods offer, and conserve open space and irreplaceable natural
resources on the urban fringe. Development in existing neighborhoods also represents
an approach to growth that can be more cost-effective, and improves the quality
of life for its residents. By encouraging development in existing communities,
communities benefit from a stronger tax base, closer proximity of a range of
jobs and services, increased efficiency of already developed land and
infrastructure, reduced development pressure in edge areas thereby preserving
more open space, and, in some cases, strengthening rural communities.
The ease of greenfield development remains an obstacle to encouraging more
development in existing neighborhoods. Development on the fringe remains
attractive to developers for its ease of access and construction, lower land
costs, and potential for developers to assemble larger parcels. Typical zoning
requirements in fringe areas are often easier to comply with, as there are
often few existing building types that new construction must complement, and a
relative absence of residents who may object to the inconvenience or disruption
caused by new construction.
Nevertheless, developers and communities are recognizing the opportunities
presented by infill development, as suggested not only by demographic shifts,
but also in response to a growing awareness of the fiscal, environmental, and
social costs of development focused disproportionately on the urban fringe.
Journals that track real estate trends routinely cite the investment appeal of
the “24-hour city” for empty nesters, young professionals, and others, and
developers are beginning to respond. A 2001 report by Urban Land Institute on
urban infill housing states that, in 1999, the increase in housing permit
activity in cities relative to average annual figures from the preceding decade
exceeded that of the suburbs, indicating that infill development is possible
and profitable.
Provide a Variety of Transportation Choices
Providing people with more
choices in housing, shopping, communities, and transportation is a key aim of
smart growth. Communities are increasingly seeking these choices --
particularly a wider range of transportation options -- in an effort to improve
beleaguered transportation systems. Traffic congestion is worsening across the
country. Where in 1982 65 percent of travel occurred in uncongested conditions,
by 1997 only 36 percent of peak travel occurred did so. In fact, according to
the Texas Transportation Institute, congestion over the last several years has
worsened in nearly every major metropolitan area in the United States.
In response, communities are beginning to implement new approaches to
transportation planning, such as better coordinating land use and
transportation; increasing the availability of high quality transit service;
creating redundancy, resiliency and connectivity within their road networks;
and ensuring connectivity between pedestrian, bike, transit, and road
facilities. In short, they are coupling a multi-modal approach to
transportation with supportive development patterns, to create a variety of
transportation options.lopment Decisions Predictable, Fair and Cost Effective
Make Development Decisions Predictable, Fair and Cost Effective
For a community to be successful in implementing smart
growth, it must be embraced by the private sector. Only private capital markets
can supply the large amounts of money needed to meet the growing demand for
smart growth developments. If investors, bankers, developers, builders and
others do not earn a profit, few smart growth projects will be built.
Fortunately, government can help make smart growth profitable to private
investors and developers. Since the development industry is highly regulated,
the value of property and the desirability of a place is largely affected by
government investment in infrastructure and government regulation. Governments
that make the right infrastructure and regulatory decisions will create fair,
predictable and cost effective smart growth.
Despite regulatory and financial barriers, developers have been successful in
creating examples of smart growth. The process to do so, however, requires them
to get variances to the codes – often a time-consuming, and therefore costly,
requirement. Expediting the approval process is of particular importance for
developers, for whom the common mantra, “time is money” very aptly applies. The
longer it takes to get approval for building, the longer the developer’s
capital remains tied up in the land and not earning income. For smart growth to
flourish, state and local governments must make an effort to make development
decisions about smart growth more timely, cost-effective, and predictable for
developers. By creating a fertile environment for innovative,
pedestrian-oriented, mixed-use projects, government can provide leadership for
smart growth that the private sector is sure to support.

At present, land use is determined by the
zoning of a plat and must be developed in accordance with that zoning
classification.. Smart Growth instead
would have specific zoning required to enhance the neighborhood and exclude
zoning that is not compatible with the neighborhood.
