Public Land Survey Issues

• Original monuments were oftenwood posts, mounds, charcoal, stones, etc.

• More often than not, these corners were not very well perpetuated over time.

Section Corners

Out of the +/-100,000 original corners in Indiana, how many are existent (i.e. properly perpetuated and referenced)?

15-20%?How many of those have state plane coordinates associated with their locations?

30% (5% of the total)?

Survey Control

There is NO inherent relationship between the land fabric and “GPS.”

Survey-grade accuracies cannot be achieved with the typical Wal-Mart purchased GPS. (Survey-grade accuracies require >$20,000 investment in equipment)

Section Corners

Average cost to perpetuate a lost or obliterated corner in Indiana:

$1000-2000 per corner

What impact does this lack of documented

corners have?

• Uncertain reference monuments

• Conflicting reference monuments

• Indeterminate reference monuments

= Higher Cost Surveys that take more time

“Sufficiency”

A legal description is considered sufficient if a competent surveyor can locate it on the ground.

Why might a description be insufficient?

Problems with Record Documents

• Descriptions that do not close• Ambiguous or missing words• Multiple possible interpretations• Plats and deeds with errors• Descriptions that follow ill-defined or

undefined rights of way• Deed gaps and overlaps with

adjoiners

Examples

• Description miscloses by over 900 feet

• “…Beginning at a stone near the corner of Kent’s barn (now gone)…”

• Bounds descriptions that call for each other

• “thence in the shape of a half-moon…”

Examples

• Description miscloses by over 900 feet

• “…Beginning at a stone near the corner of Kent’s barn (now gone)…”

• Bounds descriptions that call for each other

• “thence in the shape of a half-moon…”

• “…Also, being described by survey, as follows:…”

• An easement, 10 feet in width, adjoining and lying west of the right of way line…”
