MRE_Chapter9 Flashcards
Metes-and-bonds
- Must have a specific point of beginning (POB) 2. Must have measurement (metes = to measure) 3. Must have linear boundaries (bounds = linear directions) 4.Must completely enclose the area (return to the POB) 5. Fixed objects called monuments are used to identify the PBO, all corners of the parcel or ends of boundary segments
Rectangular Survey System
- Established by Congress in 1785 2. Based on two intersection lines 3. Range 4. Township tiers 5. Township Squares 6. Sections
Principal Meridian and Base Lines
a. Principal Meridians that runs north and south b. Base lines that run east and west C. Both Principal meridians and base lines are located in reference to degrees of longitude and latitude d. Each Principal meridian is named and is crossed by its own base line e. The rectangular survey system affects specific land areas within the boundaries
Range
- Range lines are 6 miles apart and run north and south parallel to the principal meridian 2. Range strips (ranges) are six-mile-wide strips of townships that are numbered east and west of the principal meridian
Townships Tiers
1.Township Lines are 6 miles apart and run east and west parallel to the base line 2.Township strips(tiers) are six-mile-wide strips of townships that are numbered north and south of the base line
Township Squares
- Townships are formed by intersecting pairs of township lines and range lines (the intersection of a township strip and a range strip) 2. Each township is six miles square and contains 36 square miles (36 sections) or 23,040 acres
Sections
- There are 36 sections in a township 2. They are numbered 1 thru 36, starting in the top right corner and moving east to west and then west to east 3. Each section is one square mile or 640 acres 4. Section 16 commonly is referred to as the school section
Reading a Govt Survey legal description
- Start at the end of description and work backward to the beginning 2. Begin size calculation from right hand side with section containing 640 acres,then divide by each fraction given as you move to the left of the principal meridian
Metes-and-bonds descriptions in rectangular system
- Tract is irregular 2. Tract is too small to be described by quarter sections 3. Tract does not follow the lot or block lines of recorded subdivision or section, quarter-section lines or other fractional section lines
Lot and block (recorded plat) system
- This system uses a recorded subdivision plat map 2. It requires a survey plat by a licensed surveyor or land engineer
Preparing a Survey
1.Used to locate a given parcel of land; can also amend a legal description 2. Requires the use of licensed surveyor or land engineer 3. In practice: Professional surveyor prepare a legal description
Measuring Elevations
- Condominium laws require a legal definition of the horizontal property rights included with each unit (air lots) 2. The plat map references an official datum for elevation measurement 3. Subsurface rights are also defined using a datum; subsurface rights are measured below the datum rather than above 4. Datum-a Point of reference for measuring elevations
Datum
A point of reference for measuring elevation 1. The United States Geological Survey (USGS) uses mean (avg) seal level in New York Harbor 2. Many large cities use official local datum rather than USGS datum 3. Benchmarks- Permanent reference points used primarily to mark datums; monuments are traditionally used to mark only surface measurements between points
