Plat

From Wikipedia, the free encyclopedia

A plat consists of a map, drawn to scale, showing the divisions of a piece of land. U.S. General Land Office surveyors drew township plats to show the distance and bearing between survey corners, and sometimes included topographic or vegetation information. City, town or village plats show subdivisions 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.

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.

[edit] Types of plats

A Plat 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 which would have to approve the consolidation.

A Plat 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 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.

[edit] Reasons for platting

• Designation of roads 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 utilize 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.

• Creation or vacation of easements.

• Dedication of land for other public uses, such as parks or areas needed for flood-protection.

• 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.

• Ensuring that all property has access to public utilities.

[edit] History

The word "plat" in medieval English (and ever since) refers to a piece (or "plot") of land.

The creation of a plat map marks an important step in the process of incorporating a town or city according to United States law. Because the process of incorporation must occur at a courthouse, the incorporation papers for many American cities may be stored hundreds of miles away in another state.

For example, to view the original plat for the city of San Francisco, California, filed in 1849, one must visit the Clackamas County courthouse in Oregon City, Oregon, then the capital of the Oregon Territory and the site of the closest federal land office. This happened because California did not gain statehood until 1850.
