Unit 5 Land Description Flashcards
3 methods of legal description
-metes and bounds
-rectangular survey system
-lot and block system
National Integrated Land System
developed by federal gov to coordinate land descriptions found in public records, making use of the accuracy in determining and recording property boundaries that is possible with current technology
Metes and Bounds method
measures distances (metes), starting from a Point of Beginning (POB), and following compass directions or angles (bounds) to arrive back at the point of beginning. Monuments (markers) identify the POB and corners or places where the boundary line changes direction
Rectangular (gov) Survey System
Divides land into rectangles called townships, measured from the intersection of a principal meridian and base line, and referenced by degrees of longitude and latitude.
Township lines
Run east to west, parallel to baseline, 6 miles apart
Range Lines
Run north to south, parallel to and counted from the principal meridian, 6 miles apart
Tiers
rows of townships
Ranges
Columns of townships
Townships
36 sections of one square mile (640 acres) each fun from right to left, then left to right, starting at section 1 at northeast corner of the township and ending at section 36 at the southeast corner
Lot and Block (recorded plat) method
Divides subdivision into individual parcel numbers and references all data in a subdivision plat map, noting lot sizes, street names, and other info that is approved by the governing body, and filed in public records of the county
