Title: Boundary Surveys Introduction
1Boundary Surveys Introduction
- Importance of boundary surveys
- Locate property boundaries corners and lines
- Principal reason surveying is a licensed
profession - As property values rise
- Accurate parcel delineation and description ?
more important - Land rights disputes ? more numerous
- Needed accuracy varies minimum accepted
guidelines exist
2Methods of Property Description
- Metes and bounds system
- Common throughout eastern US
- Block and lot system
- Common for e.g. subdivisions
- Description by coordinates
- Often used in US as supplement to e.g. metes and
bounds - Issues with datum specifications
- Public Land Survey System (PLSS)
- Common throughout west, midwest and southern US
3Metes and Bounds
- Concept
- Start with point of beginning (POB)
- Describe lines by directions and lengths
- Ultimately describe closed loop around parcel
- Components
- Metes
- Size and shape e.g. lengths/directions and area
- Bounds
- Intent e.g. name of adjacent owner
4Metes and Bounds Example
- Commencing at the intersection of the center
lines of Hunky-dory Road and Latitude Lane
thence N 45 00' E, 301.00' along a line to a 1"
iron pipe in concrete at the SW corner of Joe
Surveyors property thence N 10 30' W, 420.45'
to a 1" iron pipe in concrete thence N 88 45'
E, 618.27' to a 1" pipe in concrete said pipe
being located S 45 00' W, 30 feet, more or less,
from the waters edge of Triangulation Pond
thence S 12 50' E, 505.90' to a 1" pipe in
concrete at the edge of the right-of-way for
Departure Drive thence S 22 10' W, 310.60'
along the edge of the right-of-way of Departure
Drive to a 1" pipe in concrete thence N 79 20'
W, 762.70' to the point of beginning, containing
11 acres, more or less.
5Metes and Bounds Example
- Beginning at an apple tree at about 5 minutes
walk from Trefethens Landing, thence easterly to
an apple tree, thence southerly to a rock, thence
westerly to an apply tree, thence northerly to
the point of beginning.
6Metes and Bounds (contd)
- Metes and bounds descriptions should include
- Point of commencement
- Point of beginning
- Definite corners
- Lengths and directions of all property sides
- Names of adjoining property owners
- Areas
7Public Land Survey System
- Purpose
- Describe and dispose of public domain
- Without need to survey complex boundaries
- Application and history
- Applied to all areas subject to administration,
survey, and transfer of title under USA public
land laws since 1785 - In 30 states (midwest, south, and west)
- Similar systems in other areas
- Laws changed numerous times must know when
original survey was performed (follow correct
rules) - Distances in Gunter chains
8General Procedure of PLSS
- Divisions
- Divide area into tracts (24 miles)2
- Divide tracts into 16 townships, each (6
miles)2 - Divide townships into 36 sections, each (1
mile)2 - Surveying
- Set monuments to split sections while surveying
section lines - Further subdivision occurred locally
9Establishing Tracts (Step 1)
- Establish primary axis system (37 systems)
- Establish initial point
- Survey principal meridian (PM) as a true meridian
- Survey baseline as true parallel of latitude
- Establish secondary axes
- Survey standard parallels
- True parallels of latitude
- Spaced 24 miles along principal meridian (PM)
- Survey guide meridians
- Run true north between parallels
- Space standard corners at 24 mile intervals
- Mark closing corner next standard parallel
(spacing lt 24 miles)

13Establishing Township Exteriors (Step 2)
- Establish townships within each tract
- Survey meridians at 6 mile intervals from
standard corners - Survey parallels at 6 mile intervals
- Each township is nominally 6 miles square (36 sq.
miles) - Designation of townships
- East-west rows
- Called tiers
- Numbered north or south from baseline
- North-south columns
- Called ranges
- Numbered east or west from PM
14Principal meridian

Each tract is divided into 16 Townships each
nominally 6 miles ? 6 miles
15Establishing Sections (Step 3)
- Subdivide townships into 36 sections
- Section lines at 1 mile intervals
- Section nominally 1 mile square (640 acres)
- East-west section lines are parallels of latitude
- North-south section lines are parallel to
township boundary moving out from PM - Effects of meridian convergence
- Placed in northernmost row and western most
column - Sections numbered from 1 to 36 starting in NE
corner (end in SE corner)

Tier 1 North, Range 1 West

Each township is divided into 36 sections each

17Subdivision of Sections
- Quarter section corners
- Surveyed by federal surveyors while setting
section boundaries - Last step taken by federal government
- Smaller parcels of land established locally
- Connect quarter-section corners to form quarter
sections (160 acres) - Further subdivision e.g. 40 acres quarter-quarter
sections

NW ¼ NW ¼
NE ¼ NW ¼
Northeast quarter NE ¼
SW ¼ NW ¼
SE ¼ NW ¼
N ½ SW ¼
West half of Southeast quarter
E ½ SE ¼
Lot 1
Lot 2
Sections are divided into quarters and
quarter-quarters
19Example of PLSS Description
- Examples
- The SE ¼, NW ¼, Section 14, Township 1 N, Range 1
W, 1st PM - E 80 acres of NE ¼ of Sec. 20, T 5 N, R 3 E,
Michigan Prin. Mer.
20Lost and Obliterated Corners
- Issue
- Often need to deal with missing or obliterated
corners - Witness points are often also missing
- Evidence (in order)
- Evidence of corner itself
- Witness points
- Fences, walls, etc. evidence of property
occupation - Testimony
21Errors and Mistakes in Property Surveys
- Errors
- Distance/direction measurement
- Using indistinct corners
- Judgment in evaluating evidence
- Mistakes
- Not closing survey around parcel
- Not checking or performing adjustment of closure
- Using wrong corners
- Not checking deeds etc. for adjacent parcels
