, a plat ( or ) (plan) is a
cadastral map, drawn to scale, showing the divisions of a piece of land. United States
General Land Office surveyors drafted township plats of
Public Lands Surveys to show the distance and bearing between section corners, sometimes including topographic or vegetation information. City, town or village plats show subdivisions broken into
blocks with streets and alleys. Further refinement often splits blocks into individual
lots, usually for the purpose of selling the described lots; this has become known as
subdivision.
After the filing of a plat,
legal descriptions can refer to block and lot-numbers rather than portions of
sections
Section, Sectioning or Sectioned may refer to:

. In order for plats to become legally valid, a local governing body, such as a
public works department,
urban planning commission, or
zoning board must normally review and approve them.
In gardening history, in both varieties of English (and in French etc), a "plat" means a section of a formal
parterre planted only with grass, and perhaps a central feature such as a statue.
History
The creation of a plat map marks an important step in the process of
incorporating a

Types
A plat of consolidation or plan of consolidation originates when a
landowner takes over several adjacent
parcels of land and consolidates them into a single parcel. In order to do this, the landowner will usually need to make a
survey of the parcels and submit the survey to the governing body that would have to approve the consolidation.
A plat of subdivision or plan of subdivision appears when a landowner or municipality divides land into smaller parcels. If a landowner owns an
acre of land, for instance, and wants to divide it into three pieces, a surveyor would have to take precise measurements of the land and submit the survey to the governing body, which would then have to approve it. A plat of subdivision also applies when a landowner/building owner divides a multi-family building into multiple units. This can apply for the intention of selling off the individual units as condominiums to individual owners.
A correction plat or amending plat records minor corrections to an existing plat, such as correcting a
surveying mistake or a
scrivener's error. Such plats can sometimes serve to relocate lot-lines or other features, but laws usually tightly restrict such use.
A vacating plat functions to legally void a prior plat or portion of a plat. The rules normally allow such plats only when all the platted lots remain unsold and no construction of buildings or public improvements has taken place.
Other names associated with parcel maps are: land maps, tax maps, real estate maps, landowner maps, lot and block survey system and land survey maps. Parcel maps, unlike any other public real estate record, have no federal, state or municipal oversight with their development.
Reasons
* Subdivision of a property into multiple smaller lots, as described above.
* Designation of
road
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation.

s or other
rights of way.
* Ensuring that all property has access to a public right of way. Without such access, a property owner may be unable to use his or her property without having to
trespass to reach it. The platting process restricts the
fraudulent practice of knowingly selling lots with no access to public right of way without revealing that such access does not exist. (Property that does not have access to public right of way may be sold, provided that the buyer is aware of the lack of a public means of access by water or land.)
* Creation or vacation of
easements.
* Dedication of land for other public uses, such as
parks or areas needed for

A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrol ...

* Ensuring compliance with
zoning. Zoning regulations frequently contain restrictions that govern lot sizes and lot geometry. The platting process allows the governing authorities to ensure that all lots comply with these regulations.
* Ensuring compliance with a
land use plan established to control the development of a
city

Reading
Plats contain a number of informational elements:
* The property boundaries are indicated by bearing and distance. The bearing is in the format of
degrees, minutes, seconds with compass point letters before and afterward to indicate the compass quadrant. For example, N 38 00 00 E is 38 degrees into the northeast quadrant or 38 degrees east of

North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography.

National Flood Insurance Act of 1968.

land use plan
