Land use planning is the process of regulating the use of land in an effort to promote more desirable social and environmental outcomes as well as a more efficient use of resources. Goals of land use planning may include environmental conservation, restraint of urban sprawl, minimization of transport costs, prevention of land use conflicts, and a reduction in exposure to pollutants. By and large, the uses of land determine the diverse socioeconomic activities that occur in a specific area, the patterns of human behavior they produce, and their impact on the environment.
Land use involves the management and modification of natural environment or wilderness into built environment such as settlements and semi-natural habitats such as arable fields, pastures, and managed woods. It also has been defined as "the total of arrangements, activities, and inputs that people undertake in a certain land cover type."
Environmental protection is the practice of protecting the natural environment by individuals, organizations and governments. Its objectives are to conserve natural resources and the existing natural environment and, where possible, to repair damage and reverse trends.
Urban sprawl or suburban sprawl mainly refers to the unrestricted growth in many urban areas of housing, commercial development, and roads over large expanses of land, with little concern for urban planning. In addition to describing a particular form of urbanization, the term also relates to the social and environmental consequences associated with this development. In Continental Europe the term "peri-urbanisation" is often used to denote similar dynamics and phenomena, although 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 only with the average number of residential units per acre in a given area. But others associate it with decentralization, discontinuity, segregation of uses, and so forth.
In urban planning, land use planning seeks to order and regulate land use in an efficient and ethical way, thus preventing land use conflicts. Governments use land use planning to manage the development of land within their jurisdictions. In doing so, the governmental unit can plan for the needs of the community while safeguarding natural resources. To this end, it is the systematic assessment of land and water potential, alternatives for land use, and economic and social conditions in order to select and adopt the best land use options.Often one element of a comprehensive plan, a land use plan provides a vision for the future possibilities of development in neighborhoods, districts, cities, or any defined planning area.
Urban planning is a technical and political process concerned with the development and design of land use and the built environment, including air, water, and the infrastructure passing into and out of urban areas, such as transportation, communications, and distribution networks. Urban planning deals with physical layout of human settlements. The primary concern is the public welfare, which includes considerations of efficiency, sanitation, protection and use of the environment, as well as effects on social and economic activities. Urban planning is considered an interdisciplinary field that includes social engineering and design sciences. It is closely related to the field of urban design and some urban planners provide designs for streets, parks, buildings and other urban areas. Urban planning is also referred to as urban and regional planning, regional planning, town planning, city planning, rural planning, urban development or some combination in various areas worldwide.
In the United States, the terms land use planning, regional planning, urban planning, and urban design are often used interchangeably, and will depend on the state, county, and/or project in question. Despite confusing nomenclature, the essential function of land use planning remains the same whatever term is applied. The Canadian Institute of Planners offers a definition that land use planning means the scientific, aesthetic, and orderly disposition of land, resources, facilities and services with a view to securing the physical, economic and social efficiency, health and well-being of urban and rural communities.The American Planning Association states that the goal of land use planning is to further the welfare of people and their communities by creating convenient, equitable, healthful, efficient, and attractive environments for present and future generations.
Regional planning deals with the efficient placement of land-use activities, infrastructure, and settlement growth across a larger area of land than an individual city or town. Regional planning is a sub-field of urban planning as it relates land use practices on a broader scale. It also includes formulating laws that will guide the efficient planning and management of such said regions.
Urban design is the process of designing and shaping the physical features of cities, towns and villages and planning for the provision of municipal services to residents and visitors. In contrast to architecture, which focuses on the design of individual buildings, urban design deals with the larger scale of groups of buildings, streets and public spaces, whole neighbourhoods and districts, and entire cities, with the goal of making urban areas functional, attractive, and sustainable.
The Canadian Institute of Planners (CIP) is a professional organization in Canada for those involved in land use planning. The Institute has over 7,000 members from across Canada.
Land use planning often leads to land use regulation, which typically encompasses zoning. Zoning regulates the types of activities that can be accommodated on a given piece of land, as well as the amount of space devoted to those activities, and the ways that buildings may be situated and shaped.
Zoning is the process of dividing land in a municipality into zones in which certain land uses are permitted or prohibited. In addition, the sizes, bulk, and placement of buildings may be regulated. The type of zone determines whether planning permission for a given development is granted. Zoning may specify a variety of outright and conditional uses of land. It may also indicate the size and dimensions of land area as well as the form and scale of buildings. These guidelines are set in order to guide urban growth and development.
The ambiguous nature of the term “planning”, as it relates to land use, is historically tied to the practice of zoning. Zoning in the US came about in the late 19th and early 20th centuries to protect the interests of property owners. The practice was found to be constitutionally sound by the Supreme Court decision of Village of Euclid v. Ambler Realty Co. in 1926.Soon after, the Standard State Zoning Enabling Act gave authority to the states to regulate land use. Even so, the practice remains controversial today.
Village of Euclid, Ohio v. Ambler Realty Co., 272 U.S. 365 (1926), more commonly Euclid v. Ambler, was a United States Supreme Court landmark case argued in 1926. It was the first significant case regarding the relatively new practice of zoning, and served to substantially bolster zoning ordinances in towns nationwide in the United States and in other countries of the world including Canada.
The “taking clause” of the Fifth Amendment to the United States Constitution prohibits the government from taking private property for public use without just compensation. The case of Dolan v. City of Tigard demonstrated the criteria that determine the threshold of what is considered taking.One interpretation of the taking clause is that any restriction on the development potential of land through zoning regulation is a “taking”. A deep-rooted anti-zoning sentiment exists in America, that no one has the right to tell another what he can or cannot do with his land. Ironically, although people are often averse to being told how to develop their own land, they tend to expect the government to intervene when a proposed land use is undesirable.
The Fifth Amendment to the United States Constitution addresses criminal procedure and other aspects of the Constitution. It was ratified in 1791 as part of the Bill of Rights. The Fifth Amendment applies to every level of the government, including the federal, state, and local levels, as well as any corporation, private enterprise, group, or individual, or any foreign government in regard to a US citizen or resident of the US. The Supreme Court furthered the protections of this amendment through the Due Process Clause of the Fourteenth Amendment.
Dolan v. City of Tigard, 512 U.S. 374 (1994), more commonly Dolan v. Tigard, was a United States Supreme Court case. It was a landmark case regarding the practice of zoning and property rights, and served to establish limits on the ability of cities and other government agencies, to use zoning and land-use regulations to compel property owners to make unrelated public improvements.
Conventional zoning has not typically regarded the manner in which buildings relate to one another or the public spaces around them, but rather has provided a pragmatic system for mapping jurisdictions according to permitted land use. This system, combined with the interstate highway system, widespread availability of mortgage loans, growth in the automobile industry, and the over-all post-World War II economic expansion, destroyed most of the character that gave distinctiveness to American cities. The urban sprawl that most US cities began to experience in the mid-twentieth century was, in part, created by a flat approach to land use regulations. Zoning without planning created unnecessarily exclusive zones. Thoughtless mapping of these zones over large areas was a big part of the recipe for suburban sprawl.It was from the deficiencies of this practice that land use planning developed, to envision the changes that development would cause and mitigate the negative effects of such change.
As America grew and sprawl was rampant, the much-loved America of the older towns, cities, or streetcar suburbs essentially became illegal through zoning.Unparalleled growth and unregulated development changed the look and feel of landscapes and communities. They strained commercial corridors and affected housing prices, causing citizens to fear a decline in the social, economic and environmental attributes that defined their quality of life. Zoning regulations became politically contentious as developers, legislators, and citizens struggled over altering zoning maps in a way that was acceptable to all parties. Land use planning practices evolved as an attempt to overcome these challenges. It engages citizens and policy-makers to plan for development with more intention, foresight, and community focus than had been previously used.
Land use planning is defined as: the process by which optimum forms of land use and management are indicated, considering the biophysical, technological, social, economic and political conditions of a particular territory. The objective of planning land use is to influence, control or direct changes in the use of land, so that it is dedicated to the most beneficial use, while maintaining the quality of the environment and promoting conservation of the land resources. The territorial diagnosis and the generation of alternatives of management and environmental protection for the planning of the use of the land produces the indispensable knowledge necessary for the formulation of the policies of use, contributing to the search of competitive and sustainable productive and extractive activities and systems. The methodological process of land use planning contributes to: orienting the location of economic and social activities regarding the aptitude of the land and providing solutions to conflicts of use; indicate the base of natural resources that should remain and protected areas; point out the areas exposed to natural hazards and their management; identify sustainable productive and extractive activities and systems; guide the planning of land uses and indicate the areas that require land adaptation or recovery projects
In most countries, the local municipal council/local government, the body responsible of the Environment and oftentimes the national government assume all the functions of land use planning; among them the corresponding function to territorial ordering (OT). For this reason, the highlighted bodies have among other responsibilities the promotion of the conservation and sustainable use of natural resources, establishing policies, criteria, tools and procedures of the most appropriate efficient and sustainable territorial order in coordination with any other relevant corresponding entities such as construction companies and the public.
In view of sustainable development, land use planning is seen as a political and technical-administrative decision-making process agreed with social, economic, political and technical factors, for orderly occupation and sustainable use of the land under development. On the other hand, it seeks regulation and promotion of the location and sustainable development of human settlements, economic and social activities, and spatial physical development, based on the identification of potentialities and limitations that consider environmental, economic, sociocultural, institutional and geopolitical criteria.By and large, these parameters are put in place in order to make sure that the environment is protected during land use or land development. Indeed, based on the recommendations of the United Nations in its Habitat conference, land is assigned a high importance for the development of human life as it is the fundamental support for its permanence and development, this being the most important objective of the policy of human settlements. That is, the land resource is recognized as an essential element, which supports the social, political and economic formation of society. As mentioned earlier, the use of land refers to the occupation of a certain area according to its agrological capacity and therefore its development potential, it is classified according to its location as urban or rural, it represents a fundamental element for the development of the city and its inhabitants since it is from these that its urban structure is formed and therefore its functionality is defined. For this reason, there is a need to ensure sustainability in order to ensure the we continue to enjoy the benefits that come from urban planning and to ensure that future generations will continue enjoying these benefits.
To guarantee this, land use planning come into the fold. In a broader sense, this is a tool through which State defines the type of use land will have within a settlement, e.g. a city, while also determining the guidelines for its use in order to ensure effectiveness and sustainability. Land use, in this case, is assigned on the basis on its physical and functional characteristics that they have in the urban structure, and with the aim of occupying the space in an orderly manner and according to their physical capacity (occupation of areas suitable for urban development and environmental sustainability), which finally it translates into a harmonious growth of the city. This tool is structured through a planning system at the national and local level, which establishes the general guidelines that should be taken into account for the development of urban development. Here, the authorities involved might formulate a number of restrictions to guarantee sustainability, for example, banning land development in riparian zones or in national parks. Basically, the goal here is to protect the environment.
Various types of planning have emerged over the course of the 20th century. Below are the six main typologies of planning, as defined by David Walters in his book, Designing Communities (2007):
Today, successful planning involves a balanced mix of analysis of the existing conditions and constraints; extensive public engagement; practical planning and design; and financially and politically feasible strategies for implementation.
Current processes include a combination of strategic and environmental planning. It is becoming more widely understood that any sector of land has a certain capacity for supporting human, animal, and vegetative life in harmony, and that upsetting this balance has dire consequences on the environment. Planners and citizens often take on an advocacy role during the planning process in an attempt to influence public policy.Due to a host of political and economic factors, governments are slow to adopt land use policies that are congruent with scientific data supporting more environmentally sensitive regulations.
Since the 1990s, the activist/environmentalist approach to planning has grown into the Smart Growth movement, characterized by the focus on more sustainable and less environmentally damaging forms of development.Moreover, there is changes on the requirements of land use planning overtime. For example, whilst most of the urban planners suggest the distance from the landfill that a housing estate should be built, they must also take wind direction into consideration
Smart growth supports the integration of mixed land uses into communities as a critical component of achieving better places to live. Putting uses in close proximity to one another has benefits for transportation alternatives to driving, security, community cohesiveness, local economies, and general quality of life issues. Smart growth strives to provide a means for communities to alter the planning context which currently renders mixed land uses illegal in most of the country.
Professional planners work in the public sector for governmental and non-profit agencies, and in the private sector for businesses related to land, community, and economic development. Through research, design, and analysis of data, a planner's work is to create a plan for some aspect of a community. This process typically involves gathering public input to develop the vision and goals for the community.
A charrette is a facilitated planning workshop often used by professional planners to gather information from their clients and the public about the project at hand. Charettes involve a diverse set of stakeholders in the planning process, to ensure that the final plan comprehensively addresses the study area.
Geographic Information Systems, or GIS, is a very useful and important tool in land use planning. It uses aerial photography to show land parcels, topography, street names, and other pertinent information. GIS systems contain layers of graphic information and their relational databases that may be projected into maps that allow the user to view a composite of a specific area, adding an array of graphically oriented decision making tools to the planning process.
A transect, as used in planning, is a hierarchical scale of environmental zones that define a land area by its character, ranging from rural, preserved land to urban centers. As a planning methodology, the transect is used as a tool for managing growth and sustainability by planning land use around the physical character of the land. This allows a community to plan for growth while preserving the natural and historical nature of their environment.
Natural ecology and historical identity of the city are matched to its topography in the Urban Landscape System approach that intends to mitigate effects of climate change and improve city branding through the ontology of place.
Police power is the basis for land use planning authority in the United States. This authority is usually delegated by state governments to local governments, including counties and cities. It is these local governments that most frequently exercise police power in land use planning matters. The regulation of land use based on police power is distinct from the taking of private property by the government through the power of eminent domain. If the regulation of land use is done under the authority of the police power, the private property owner isn't typically entitled to compensation as they would be if property was taken under the power of eminent domain. The court decision in the case Commonwealth v. Alger was related to land use planning and dealt with the construction of a wharf on privately owned tidelands around Boston Harbor.
Milan city is located in northern Italy. It is the second most populous city in the country after Rome with a population of over 4 million (The CBD and its metropolitan Boroughs).
Every area in Milan is a segment that starts from the center and reaches the city limits, so that central areas and peripheral areas are part of the same area. In Milan, zones are not identified by names but numbers. The city hall area 1 of Milan includes the entire historical center, starting from the geographical center of Milan in Piazza Duomo up to the Cerchia dei Bastioni. The town hall area 2 goes from Piazza della Repubblica to Crescenzago, Turro, Greco and Precotto. The town hall 3 goes from Porta Venezia to Lambrate, passing through Città Studi.
The town hall area 4 goes from Porta Vittoria to the Forlanini park, also including Porta Romana, Corvetto and Santa Giulia. The town hall 5 goes from Porta Ticinese to the Agricultural Park, passing through Chiesa Rossa and Gratosoglio. The town hall 6 goes from the Darsena, up to Barona, Lorenteggio and Giambellino. The city hall area 7 goes from Porta Magenta to Baggio and Figino passing through San Siro. The town hall zone 8 goes from Porta Volta to Quarto Oggiaro, passing through QT8 and Gallaratese. And lastly, the town hall area 9 goes from Porta Nuova to Niguarda and Bovisa. The idea here, is to allow members of the nine zones to get easy access to the CBD. Effective measures have been put in place to limit the impact of human activates on the many water bodies in this city such as restricting land development in riparian areas. In fact, the drive for the establishment of the city on the land where it stands was easy accessibility to water.
Due to the increasing discussions in the issues of climate change and global warming, the future of land use planning will be dominated by environmental sustainability themes more than economic convenience.
Smart growth is an urban planning and transportation theory that concentrates growth in compact walkable urban centers to avoid 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" 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.
Landscape planning is a branch of landscape architecture. According to Erv Zube (1931–2002) landscape planning is defined as an activity concerned with developing landscaping amongst competing land uses while protecting natural processes and significant cultural and natural resources. Park systems and greenways of the type designed by Frederick Law Olmsted are key examples of landscape planning. Landscape designers tend to work for clients who wish to commission construction work. Landscape planners analyze broad issues as well as project characteristics which constrain design projects.
(See also the Form-based section of the Zoning in the United States article.)
Environmental planning is the process of facilitating decision making to carry out land development with the consideration given to the natural environment, social, political, economic and governance factors and provides a holistic framework to achieve sustainable outcomes. A major goal of environmental planning is to create sustainable communities, which aim to conserve and protect undeveloped land.
Mixed-use development is a term used for two related concepts:
SmartCode is a unified land development ordinance template for planning and urban design. Originally developed by Duany Plater-Zyberk & Company, this open source program is a model form-based unified land development ordinance designed to create walkable neighborhoods across the full spectrum of human settlement, from the most rural to the most urban, incorporating a transect of character and intensity within each. It folds zoning, subdivision regulations, urban design, and basic architectural standards into one compact document. Because the SmartCode enables community vision by coding specific outcomes that are desired in particular places, it is meant to be locally calibrated by professional planners, architects, and attorneys.
Urban, city, or town planning is the discipline of planning which explores several aspects of the built and social environments of municipalities and communities:
Green infrastructure or blue-green infrastructure is a network providing the “ingredients” for solving urban and climatic challenges by building with nature. The main components of this approach include stormwater management, climate adaptation, less heat stress, more biodiversity, food production, better air quality, sustainable energy production, clean water and healthy soils, as well as the more anthropocentric functions such as increased quality of life through recreation and providing shade and shelter in and around towns and cities. Green infrastructure also serves to provide an ecological framework for social, economic and environmental health of the surroundings. Green Infrastructure is considered a subset of Sustainable and Resilient Infrastructure, which is defined in standards such as SuRe - the Standard for Sustainable and Resilient Infrastructure. However, green infrastructure can also mean "low-carbon infrastructure" such as renewable energy infrastructure and public transportation systems. Blue-green infrastructure can also be a component of "sustainable drainage systems" or "sustainable urban drainage systems" designed to manage water quantity and quality, while providing improvements to biodiversity and amenity.
Activity centre is a term used in urban planning and design for a mixed-use urban area where there is a concentration of commercial and other land uses. For example, the central business districts of cities (CBD) are also known as “Central Activities Districts” (CAD) (also known as Downtown in North America or "Central Activities Zone" in the United Kingdom in recognition of the fact that commercial functions are not the only things that occur there. The term activity centre can also be used to designate an area for mixed-use development, whatever its current land use happens to be.
Comprehensive planning is a process that determines community goals and aspirations in terms of community development. The result is called a comprehensive plan and both expresses and regulates public policies on transportation, utilities, land use, recreation, and housing. Comprehensive plans typically encompass large geographical areas, a broad range of topics, and cover a long-term time horizon. The term comprehensive planning is most often used by urban planners in the United States.
Joe A. Porter is a professional landscape architect and Fellow of the American Society of Landscape Architects. For the past thirty years, Mr. Porter has worked with new community, natural resource, and resort developers to advance the art of community development through design. In 1969 Mr. Porter co-founded Design Workshop. Design Workshop is an award-winning, international firm practising landscape architecture, land planning, urban design and tourism planning. He is currently an adjunct professor in the graduate program in landscape architecture at the University of Colorado and frequently speaks at conferences and universities on community development and sustainability issues.
A site plan is an architectural plan, landscape architecture document, and a detailed engineering drawing of proposed improvements to a given lot. A site plan usually shows a building footprint, travelways, parking, drainage facilities, sanitary sewer lines, water lines, trails, lighting, and landscaping and garden elements.
An urban planner is a professional who practices in the field of urban planning.
The compact city or city of short distances is an urban planning and urban design concept, which promotes relatively high residential density with mixed land uses. It is based on an efficient public transport system and has an urban layout which – according to its advocates – encourages walking and cycling, low energy consumption and reduced pollution. A large resident population provides opportunities for social interaction as well as a feeling of safety in numbers and "eyes on the street". It is also arguably a more sustainable urban settlement type than urban sprawl because it is less dependent on the car, requiring less infrastructure provision.
Technical aspects of urban planning involve the technical processes, considerations and features that are involved in planning for land use, urban design, natural resources, transportation, and infrastructure.
Complete communities is an urban and rural planning concept that aims to meet the basic needs of all residents in a community, regardless of income, culture, or political ideologies through integrated land use planning, transportation planning, and community design. While the concept is used by many communities as part of their community plan, each plan interprets what complete community means in their own way. The idea of the complete community has roots in early planning theory, beginning with The Garden City Movement, and is a component of contemporary planning methods including Smart Growth.
