about the neighborhood
A city block, urban block or simply block is a central element of urban
planning and urban design.
A city block is the smallest area that is surrounded by streets. City blocks are
the space for buildings within the street pattern of a city, and form the basic
unit of a city's urban fabric. City blocks may be subdivided into any number of
smaller land lots usually in private ownership, though in some cases, it may be
other forms of tenure. City blocks are usually built-up to varying degrees and
thus form the physical containers or 'streetwalls' of public space. Most cities
课
are composed of a greater or lesser variety of sizes and shapes of urban block.

For example, many pre-industrial cores of cities in Europe, Asia and the

究
Middle-east tend to have irregularly shaped street patterns and urban blocks,
while cities based on grids have much more regular arrangements.
In most cities of the world that were planned, rather than developing gradually
over a long period of time, streets are typically laid out on a grid plan, so that
city blocks are square or rectangular. Using the perimeter block development
principle, city blocks are developed so that buildings are located along the
perimeter of the block, with entrances facing the street, and semi-private
courtyards in the rear of the buildings.[1] This arrangement is intended to
provide good social interaction among people.
Since the spacing of streets in grid plans varies so widely among cities, or even
within cities, it is difficult to generalize about the size of a city block. However,
as reference points, the standard square blocks of Portland, Houston, and
Sacramento are 260 by 260 feet (79 × 79 m), 330 by 330 feet (100 × 100 m),
and 410 by 410 feet (120 × 120 m) respectively (to the street center line).
Oblong blocks range considerably in width and length. The standard block in
Manhattan is about 264 by 900 feet (80 × 270 m); and in some U.S. cities
standard blocks are as wide as 660 feet (200 m). The blocks in Edmonton,
Canada are 560 by 330 feet (170 × 100 m).[2] The blocks in central Melbourne,
Australia, are 660 by 330 feet (200 × 100 m), formed by splitting the square
blocks in an original grid with a narrow street down the middle.
Many world cities have grown by accretion over time rather than being planned
思
from the outset. For this reason, a regular pattern of even, square or
维
rectangular city blocks is not so common among European cities, for example.
训
Following the example of Philadelphia, New York City adopted the
练
Commissioners' Plan of 1811 for a more extensive grid plan. By the middle of
the 20th century, the adoption of the uniform, rectilinear block, subsides almost
completely and more picturesque layouts prevailed, with random sized and
either curvilinear or non-orthogonal blocks and corresponding street patterns.
In much of the United States and Canada, the addressing systems follow a block
and lot number system, in which each block of a street is allotted 100 building
numbers. In North American English the term block is used as an informal unit
of distance; for example, when giving directions (e.g. "It's three blocks from
here.").
In British English the term is scarcely used to convey a measure of distance due
to the lack of 'blocks' in most cities; it is, however, used when making short
trips around a nearby road of an estate (e.g. "I'm taking the dog out for a walk
around the block").
