City planning embraces the organisation, or conscious influencing, of land-use distribution in an area already built-up or intended to become built-up.
In ancient times, Romans used a consolidated scheme for city planning, developed for military defense and civil convenience. Effectively, many European towns still preserve the essence of these schemes, as in Turin. The basic plan is a central plazaPlaza is a Spanish word related to "field" which describes an open public space, such as a town square. More recently it has been used to describe a shopping complex, similar to a shopping mall, borrowing its connotations of a center of cultural life. with city services, surrounded by a compact grid of streets and wrapped in a wall for defense. To reduce travel times, two diagonal streets cross the square grid corner-to-corner, passing through the central square. A river usually flows through the city, to provide water and transport, and carry away sewage, even in sieges.
In developed countries there has been a backlash against excessive man-made clutter in the environment, such as bollards (signposts), signs, and hoardings (temporary fences around construction sites). Other issues that generate strong debate amongst urban designers are tensions between peripheral growth, increased housing density and planned new settlements. There are also unending debates about the benefits of mixing tenures and land uses, versus the benefits of distinguishing geographic zones where different uses predominate.
Successful urban planning considers character, of "home" and "sense of place", local identity, respect for natural, artistic and historic heritage, an understanding of the "urban grain" or "townscape," pedestrians and other modes of traffic, utilities and natural hazards, such as flood zones.
Some say that the medieval piazzaA piazza is an open square in a city, often used as a marketplace, found in Italy. It is roughly equivalent to the Spanish plaza. Piazza has taken some slightly different meanings in Britain and the US. In Ethiopia, it is used to refer to a pary of a city and arcade are the most widely appreciated elements of successful urban design, as demonstrated by the Italian cities of SienaThis page is not about the form of limonite clay called sienna. Siena is a city in Tuscany, Italy. Siena was an Etruscan settlement and a small Roman town, the seat of a Christian bishop by the 5th century, but its importance began in the early 12th centu and BolognaBologna (from Latin Bononia Bulaggna in the local dialect) is the capital city of Emilia-Romagna in northern Italy, between the Po River and the Apennines.

While it is rare that cities are planned from scratch (and, in case, with some risk of unsuccessful examples like for BrasíliaBrasilia is the capital city of Brazil and is located in the center of the country in a federal district created in the state of Goias. It is between 15°30' and 16°03' South latitude, limited by the Preto River on the East and by the Descoberto River on t), planners are important in managing the growth of cities, applying tools like zoning to manage the uses of land, and growth managementGrowth management is a set of techniques used by government to ensure that as the population grows that there are services available to meet their demands. These are not necessarily only government services. Other demands such as the protection of natural to manage the pace of development. When examined historically, many of the cities now thought to be most beautiful are the result of dense, long lasting systems of prohibitions and guidance about building sizes, uses and features. These allowed substantial freedoms, yet enforce styles, safety, and often materials in practical ways. Many conventional planning techniques are being repackaged as smart growthSmart growth development policies aim to prevent urban sprawl and pollution, and reduce the profligate use of non-renewable fuels, particularly an excessive dependency on private cars in industrialised countries. Such policies emphasize sustainability, de.
There are some cities that have been planned from conception, and while the plans often don't turn out quite as planned, evidence of the initial plan often remains. See List of planned citiesThis is a list of planned cities (sometimes known as planned communities or new towns) by country. Additions to this list should be cities whose overall form (as opposed to individual neighborhoods or expansions) has been determined in large part in advan. Some of the most successful planned cities consist of cells that include park-space, commerce and housing, and then repeat the cell. Usually cells are separated by streets. Often each cell has unique monuments and gardening in the park, and unique gates or boundary-markers for the edges of the cell. The commercial areas naturally become diverse. These differences help instill a sense of place, while the similarities of the cells make each place in the city familiar.
