Unit 8 Flashcards
Identify the three methods used to describe real estate.
The three main methods used to describe real estate are metes and bounds, the rectangular (government) survey system, and the lot-and-block (recorded plat) system. These methods provide precise, legally sufficient descriptions that are essential for property transactions.
Explain how to read a metes-and-bounds survey description, how to divide a section of land, and how to calculate the acreage in a tract of land.
A metes-and-bounds description starts from a point of beginning (POB) and follows boundaries using directions and distances. Dividing a section involves subdividing the 640-acre sections of a township, and acreage is calculated by multiplying the fractions of these sections.
Describe how a survey is prepared and how a datum and a benchmark relate to that process.
Surveys are prepared by licensed surveyors to determine the boundaries of a property using legal descriptions. A datum is a reference point used to measure vertical heights or depths, and a benchmark is a permanent marker used to help surveyors with accurate elevation data.
Distinguish the various units of land measurement.
Common land measurement units include acres (43,560 square feet), sections (640 acres), townships (36 square miles), and varas (33 ⅓ inches). These units are used to describe the size and location of parcels in legal descriptions.
Air lot
A designated parcel of airspace located above a piece of land, often used in multi-story developments like condominiums. Ownership of an air lot does not include the surface land beneath it.
Base line
An east-west line in the rectangular (government) survey system used to establish a grid for measuring land. Base lines intersect with principal meridians to create a reference system for land descriptions.
Benchmark
A permanent reference point set by surveyors, often marked in a durable material, used to measure elevations relative to a datum. Benchmarks provide critical accuracy for surveys involving vertical measurements.
Datum
A horizontal plane used as a reference point from which land elevations are measured. The most commonly used datum is sea level, and it is essential for measuring heights and depths on a property.
Improvement survey
A type of survey that shows the location, size, and shape of buildings and other structures on a property, in addition to the legal description of the land. This survey is used to assess property boundaries and the placement of improvements.
Legal description
A detailed, legally sufficient description of a parcel of land, used to identify property in deeds and contracts. Common methods include metes and bounds, rectangular survey, and lot-and-block systems.
Legally sufficient
A term used to indicate that a property description is complete enough to identify the parcel being referenced for legal purposes. It must be clear and accurate enough for surveyors and courts to rely on.
Lot and block
A method of describing property based on a recorded subdivision plat. The property is identified by referencing lot and block numbers on the recorded map, often used in residential subdivisions.
Metes and bounds
A system of describing land by measuring distances (metes) and using natural or man-made boundaries (bounds). This system typically starts from a point of beginning (POB) and traces the property’s perimeter.
Monument
A physical object, either natural or man-made, used to mark the boundaries of a property in a metes-and-bounds description. Monuments provide reference points for surveyors and property owners.
Point (place) of beginning
The starting point in a metes-and-bounds description, from which the property boundaries are measured. The description follows a path back to the POB to enclose the property.
Principal meridian
A north-south line in the rectangular (government) survey system that serves as the primary reference point for land descriptions. It intersects with base lines to create a grid for organizing land into sections and townships.
Range
A strip of land six miles wide, running north and south, in the rectangular (government) survey system. Ranges are numbered east or west from a principal meridian and are used to describe the location of townships.
Recorded subdivision plat
A map of a subdivision that shows the layout of lots, blocks, streets, and public areas. The plat is recorded with local authorities and is used to legally describe properties in a subdivision.
Rectangular survey system
Also known as the government survey system, this method divides land into townships and sections using principal meridians and base lines. It is primarily used in western and midwestern states.
