Land-use planning

Land use planning or land-use regulation is the process of regulating the use of land by a central authority. Usually, this is done to promote more desirable social and environmental outcomes as well as a more efficient use of resources. More specifically, the goals of modern land use planning often include environmental conservation, restraint of urban sprawl, minimization of transport costs, prevention of land use conflicts, and a reduction in exposure to pollutants. In the pursuit of these goals, planners assume that regulating the use of land will change the patterns of human behavior, and that these changes are beneficial. The first assumption, that regulating land use changes the patterns of human behavior is widely accepted. However, the second assumption – that these changes are beneficial – is contested, and depends on the location and regulations being discussed.
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.
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. Land-use planning in England and Wales is founded on the Town and Country Planning Act 1947, with comparable legislation applicable in Scotland and Northern Ireland.

History

Land use planning nearly always requires 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.
The ambiguous nature of the term "planning", as it relates to land use, is historically tied to the practice of zoning. Zoning in the United States 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 model law known as the Standard State Zoning Enabling Act was enacted by many state legislatures, which gave authority to the states and its subdivisions to regulate land use. Even so, the practice remains controversial today, particularly in its impact on economic and racial segregation, as some critics argue that zoning has often been used to exclude certain populations from particular neighborhoods.
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.
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 urban 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.

Description and application

Description

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 and maintains 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.

Planning process and parties involved

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. 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.

Application

"Developing cities and towns": land use planning is an important component of city planning. The nature of cities required to the most beneficial use in terms of maximization of economic factors and promoting convenience, while maintaining the quality of the environment and promoting conservation of the land. The only way to achieve this is the utilization of the elements of land use planning.
"The concept of Zoning": Zoning is the process by which areas of land are split into zones by appropriate establishments within which several users are assigned to each zone. Therefore, this makes zoning very important modus operandi in land use planning where it is used to design urban areas in many countries. The topic of zoning is considered within the context of land use planning and design as a systemic perception. Zoning is used as a fundamental component of territorial planning, which is incorporated in the stages of the logical model of regional development. In the process of zoning, the actor divides land into units of different sizes, shapes and locations, according to the characteristics of the terrain and the corporality of a culture. The actor who generates a multiplicity of spaces using zoning, based on global spatial unit and the preferences of user who uses these spaces in multiple use form, decomposes his vision of it into four different dimensions namely; deontic, cognitive, expressive and aesthetics functions. Each of these dimensions represents land in different forms, intensities, positions and areas, which may not coincide with each other. The deontic space is that of the transforming actions of the world, of the duty to be and to do. The cognitive space is apprehended by the faculties of knowledge from the senses to the reason, such as the ecological and technological spaces. The aesthetic space refers to the scopes of feel and beauty. The expressive or indexical space corresponds to the internal and cultural expression of the identity of the person who organizes the space. Often, a fifth space is included, that is, the administrative space, which concerns the positioning of the legal, authoritative and legislative base being planned. Zoning should not be considered as the end in itself, but only as a means of approximation in relation to geographical reality. Instead of imposing pre-established categories, it is about looking for landscape discontinuities. The category system must allow a deepening of the landscapes according to their scale. For each order of phenomena there are thresholds of manifestation and "extinction" that by themselves can justify the systematic differentiation of landscapes into hierarchical units. The study and zoning of the coverage and land use requires first defining the concepts of land, coverage and use in order to avoid the problems of interpretation associated with the management of these concepts. The concept of land is defined as an entity formed by the mutual interaction of living and non-living nature in a recognizable portion of the Earth's surface. It is a more geographical than edaphological definition. The earth is conceived as the result of the integration of biophysical and socioeconomic elements whose interrelation generates certain particular spatial units or landscapes, therefore, land and landscape are considered in this guide as synonyms. Land cover, on the other hand, is defined as the different features that cover the land, such as water, forest, other types of vegetation, bare rocks or sand, man-made structures, etc. In general, these are the traits that can be directly observed in aerial photographs and frequently in satellite images. The concept of use, applies to the employment that man gives to different types of coverage, cyclically or permanently to meet his material or spiritual needs. Basically, this is where the need for zoning arises.
